Scrubber are an efficient type of air pollution control equipment used to remove particulate matter, fume and gases (especially acid gases) from industrial processes. Scrubbing can be done either by wet or dry mechanism which then categorise the equipments into dry and wet scrubbers. Wet scrubbers are pollution control equipment that use water or other liquid solutions to scrub particulate matter and harmful gases from the gas stream. However, the dry scrubbers are that in which a dry reagent or slurry is injected into the dirty exhaust stream of gases to neutralise or eliminate gaseous components.


Wet scrubbers eliminate particulate matter from exhaust gas streams by capturing the particles in fine liquid mist droplets or in layers of scrubbing liquid and then separating the liquid droplets from the gas stream.

There are various process variables which affect the performance of particle removal or performance of the scrubber, being, particle size distribution, size of liquid mist droplets, and the relative velocity of the particles and the liquid mist droplets. The most important parameter is the particle size of the inlet dust content. The larger particles are easier to collect as compared to the finer ones. The key factor for effective particle removal in a wet scrubber is, to create a mist of tiny liquid droplets which acts as collection surfaces. Higher scrubbing efficiency for finer particles can be expected when scrubbing liquid is with the finer mist droplets and more densely available.

Efficiency of scrubber depends upon the following major parameters:

  • Formation of mist of tiny droplets
  • Higher resistance production by creation of suitable pressure drop
  • Selection of suitable scrubbing liquid for gaseous pollutants
  • Higher relative velocities between dust particles & liquid droplets
  • Uniform mixing between gas molecules and liquid phase
  • Treatment and reaction time between liquid droplets and gas molecule
  • Selection of appropriate liquid to gas ratio

Design of Wet Scrubber:
  • The configuration of wet scrubbers or some other air pollution control system is determined by the manufacturing process conditions and the type of air pollutants involved. The properties of the inlet gas and dust are of the utmost importance. Scrubbers may be engineered to collect particulate matter as well as gaseous emissions. Wet scrubbers' flexibility allows them to be installed in a variety of configurations, all of which are engineered to have good contact between the liquid and dirty gas stream.

Features:
  • High dust collection efficiency
  • Simple and trouble-free design

Electrostatic Precipitator  is a filtration device that removes fine particles, like dust and smoke, from a flowing gas by the force of an induced electrostatic charge minimally impeding the flow of gases through the unit. In contrast to wet scrubbers, which apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and therefore is very efficient in its consumption of energy.

Types of ESP:
  • Dry type Electrostatic Precipitator: Dry Electrostatic Precipitators (ESPs) can be used in many industries for various applications for cleaning of dust laden industrial gases. ESPs can handle any volume of gases and many types of dusts with high removal efficiencies. The continuous improvement in design & engineering of the ESPs reduce the operating costs by reducing the energy consumption, maintenance cost and lower downtime. The ESP components are well designed by using most advance technologies.
  • Wet Electrostatic Precipitator: Tar Precipitator also termed as Wet Electrostatic Precipitator. The Wet Electrostatic Precipitator compliments our product range with an extremely versatile de- dusting system that is perfect for any process in which special dust or gas characteristics make dry separation difficult or impossible.
  • The Wet ESPs are unbeatable since many years in view of operational safety, long life cycle and high collection efficiency. They are well suited for precipitation of finest dust with dust afflicted water drops of aerosols and emissions containing tar or oil. Another, positive effect is the additional bound of toxic elements (for example HCL, SO2, NaCL & HF)


Working Principle:

  • The dust laden gases are passed through the electrical field consisting of profiled collecting electrodes and discharge electrodes. The discharge electrodes are charged with negative high voltage and the collecting electrodes are earthed. The gas is equally distributed and made to pass through these gaps of electrodes across width and length.
  • The discharged electrodes emit electrons when charged with high negative voltage. These negative electrons accumulate on dust particles and thus dust particles are charged negatively. The charged dust particles are attracted towards the profiled collecting electrodes. When the dust particles touch the collecting electrodes, it loses its charge, but due to agglomeration, they still stick to the plate. These electrodes are cleaned with the use of robust tumbling hammer type rapping system. Independent rapping systems are used to clean the collecting as well as discharge electrodes.


Our ESPs are optimally designed, tailor-made to suit the customer operating conditions. The migration velocity is an extremely important parameter to decide the size of the ESP and helps to determine the efficiency. Apart from this, there are many parameters which affect the sizing of the ESP such as:

  • Electrical resistivity of the dust
  • Dust content at inlet & outlet of ESP/strong>
  • Chemical composition of dust & gas
  • Particle size of dust
  • Temperature of gas
  • Humidity in gas

Advantages:
  • Rigid Pipe & Spike type discharge electrodes.
  • Sturdy & durable collecting electrodes for longer life.
  • Separation of ultra-fine dust particles to meet the required lower emission norms.
  • Continuous dust collection process.
  • Low pressure drop (approx. 2.5 mbar) at high degree of separation.
  • Low maintenance due to few and slowly rotating components.
  • Low energy costs compared to Fabric Filter separators.
  • Can handle large volume of gas flow, virtually there is no upper limit.
  • Handling high gas temperatures.

In various applications of Bag filters in the industries height and/or footprint constraint is the most common issue and conventional type of bag filters cannot be accommodated easily. For such critical areas, cartridge type bag filters are the most suitable solution with less space requirement and without compromising on the guaranteed parameters. These bags are assembled in pleated type format and thus provides more filtration area than the conventional bags. They are available in different constructions i.e. difference number of pleats mainly 45 or 60, 60 with higher filtration area. They are also available in different lengths of upto 2.0 mtr.


The Cartridge Bag filters are mainly dry separation air pollution equipment for dust particles or for product recovery of useful products from air or any other gas flow of the manufacturing process. These filters vary from the lowest volume of 100 m3/hr to maximum volume depending on the process requirement.

Construction & Operation:

Cartridge Bag Filter is divided in three parts i.e. top part is called as Plenum (Clean air chamber), which is heart of the bag filter operation, middle one is called as Housing/casing (Dirty air chamber) and bottom part is called as Hopper. The plenum is separated from the housing by the bag plate/tube sheet where the cartridge filter bags. The Cartridge Bag Filter unit is a continuous self cleaning dust filter capable of removing dust particles as small as submicron size from gaseous and dust streams.

Cartridge Bag filter construction is simple and does not have any moving parts. Pulsejet cleaning mechanism with the help of compressed air results into high dust cleaning efficiency.

Dust laden air enters the cartridge Bag Filter at housing under suction or pressure. The air travels through the cartridge filters which retains the dust particles on the surface of the cartridge filters and the clean air passes through cartridge filters to the plenum leading to the outlet of Cartridge bag filter due to the suction effect created by centrifugal ID fan.

Dust collected on the outside of the Cartridge filter bags causes an increase in the pressure differential between the dirty and clean air sides of the filter. To control the pressure differential across the cartridge bag filter, a sequential timer actuates a series of normally closed pulse valves at preset intervals causing them to open. A momentary rush of high-pressure air (5-7 bar g) flows from the compressed air header to the blow tube and is expelled from the blow tube for the effective cleaning of cartridge bags.

Above cleaning cycle causes the dust particle to fall in the collection hopper. Collection hopper stores the collected dust temporarily. The dust is discharged from hopper bottom through RAL or Screw conveyor to the downstream process.

Fumes Extraction systems (FES) are air pollution control equipment installed to capture fugitive fume gases, smoke and dust emission generated from various heat processes which are hazardous and detrimental to human health and environment.

Typical Operation:
The Furnace comes with Smoke Collection Hood of Low Hood Design, which prevent any fugitive gas emissions. The gas emissions emanating from the furnaces are collected by the smoke collection hoods and passed on to a smoke chimney / stack by natural draft. The smoke chimney has a butterfly valve just a little above the top of the smoke hood with the help of which, the gas emissions are directed to the Air Pollution Control equipment. These gases from the point of Butterfly valve are sucked by means of a powerful I.D. (Induced Draft) fan into the Pollution Control Equipment.

Sparks if any in gas stream are extinguished in ductwork, bends & in Heat Exchanger (Forced Draft Cooler) due to changes of direction. First, gases are passed through a tubular forced draft cooler where they get cooled by atmospheric air being blow over the tubes with the help of axial cooling fans. The much heavier particles in the gases get settled at the bottom of the cooler. The gas with the remaining heavier particles goes to a multi-chamber Bag Filter System after which the I.D. fan is installed. When the gas passes through the filter bags, the dust present in the gases is trapped by these bags and only clean gas comes out of the Bag Filter. This clean gas is then released through the stack to atmosphere.


Bag House Cleaning:
  • During this process, the bags in the multi-chamber bag filter house collect fume dust and need to be cleaned. The Bag house cleaning is "OFF LINE" (with one compartment isolated) and "ON - DEMAND" on the basis of pressure drop across the bag house. When the pressure drop exceeds the set point, Master controller shall close the Poppet damper at the outlet of the compartment and start cleaning the bags till the pressure drop reaches lower set point. Cleaning is done by compressed air pulses so that the dust accumulated on the bags surface gets shrugged off and gets collected into a collection hopper provided at the bottom of the bag filter housing. After reaching lower set point, cleaning shall stop and Poppet 
  • Damper shall open. This cleaning operation shall be done in a sequential fashion as and when pressure drop exceeds preset limits. This loop shall ensure optimum cleaning of the filter bags to improve bag life and reduce emission levels. Accordingly, one chamber after another gets cleaned in a pre-determined cycle.

Tapping Fumes Fan (Booster Fan):
  • We consider the tapping fumes fan for each furnace, as it works on positive as well as negative pressure, it sucks the fumes from tap hole and pushes it towards the bag filter.

Isolation of Complete System:
  • Further, system isolation damper with actuator is provided which will isolate the complete system and furnace stack dampers are opened for venting the gases. This provision is useful in the event flue gas temperature is excessively high even after dilution damper is open. Moreover, if it is desired for purpose of maintenance, entire Gas cleaning plant can be isolated by operating these 2 numbers actuated dampers provided at the take off point near furnace hood.

Dust Extraction System is one of the mainly used method to reduce the work zone emissions and emissions through exhaust stacks and ducts. It is installed on material handling systems or at the vent of production process as a product collection system.


Construction of bag filter:
  • Bag Filter is divided in three parts i.e. top part is called as Plenum (Clean air chamber), which is heart of the bag filter operation; middle one is called as Housing/casing (Dirty air chamber) and bottom part is called as Hopper. The plenum is separated from the housing by the bag plate/tube sheet where the filter bags and cages i.e. the filtering elements are supported. The Bag Filter unit is a continuous self- cleaning dust filter, capable of removing dust particles as small as submicron size from gaseous and dust streams.
  • Bag filter construction is simple and doesn’t have any moving parts. Pulsejet cleaning mechanism with the help of compressed air results into high dust cleaning efficiency.
  • Refer to the diagram above white plate shown is called as Baffle plate which avoids the direct impact of dusty gases on the bags causing majority of heavy particles to settle down in the hopper. Remaining fine particles travel in upward direction and further filtration is done through filter bags. After filtration clean gases pass through specially designed clean air chamber called as plenum.

Working Principle for DE systems:
  • Dust generating points inside the plants like belt conveyor transfer points, crusher venting, screen venting etc. is connected to the bag filter inlet by duct work.
  • For Dust Extraction system applications, the no. of points from where the air borne dust is getting generated are provided with suction hoods and manual or motorized dampers in ducting depending upon the application. The dampers are provided for balancing so that optimum suction is obtained at each suction point. These hoods are connected by small duct network to the main duct header which is finally connected to the bag filter.

Operation:
  • Dust laden air enters the Bag Filter at housing under suction or pressure. The air travels through the filter bags which retains the dust particles on the surface of the bag and the clean air passes through the filter bags to the plenum leading to the outlet of Bag Filter due to the suction effect created by centrifugal ID (induced draft) fan.
  • Dust collected on the outside of the filter bags causes an increase in the pressure differential between the dirty and clean air sides of the bag filter. To control the pressure differential across the bag filter, a sequential timer actuates a series of normally closed pulse valves at preset intervals causing them to open.
  • A momentary rush of high-pressure air (5-7 bar g) flows from the compressed air header to the blow tube and is expelled from the blow tube through venturies at high velocity (primary air flow). Air from each venturi induces a secondary airflow. The combined effect of the primary and induced secondary air causes an instantaneous pressure to rise on the clean side of the filter bags, causing a reverse flow of air through the filter bags, thus dislodging the dust.
  • With our experience and expertise, we have solutioned various critical applications. We have the ability to design systems complying to work zone and outlet emissions norms established by pollution control board or client requirement. Emission parameters are achieved by designing the suction hoods, duct network, velocities and pressure at different points based on ACGIH guidelines.
  • Apart from Bag Filters, electrostatic precipitators or scrubbers can also be used. Our sales and application experts recommend the type of pollution control equipment to be used based on the application requirement.

Sparks in the fumes collected in the equipment are called as spark arrestor. The spark arrestor reduces the risk of fire or burns in the industrial dust collection system.


The spark arrestor is a passive fire protection device. The primary purpose is to break the heat envelope around the spark by creating turbulence. This is possible due to the fixed guided vanes inside the spark arrestor which breaks the laminar flow & spark within flow converts to dust/ash which then are collected in lower hopper. Spark arrestors also acts as a pre-separator/pre-dust collector and reduces the dust load in the bag house.


Spark arrestor is recommended as part of a complete fire prevention system. Spark arrestor is a vital protection device which saves the main equipment/system from getting damaged.


For some applications spark arrestors are a must. If not provided, the spark can travel through the ductwork and ignite combustible dust or other materials or will burn the bags of Bag filter.


A Spark Arrestor plays an instrumental part & it’s working to minimize risk by cooling and thus extinguishing sparks before they reach the filter surface. The spark arrestor fits within the full dust collection system as the first line of defence.

Features:

  • Reduce dust load of bag house.
  • Arrests sparks from the fumes.
  • Minimize risks by cooling before it reaches filter surface.

Usage/ApplicationCleaning Mini Blast Furnace Gases

Gas Cleaning Plants are used for cleaning the outlet gases of Mini Blast Furnace in the steel industries. These gases are hazardous in nature and contain high calorific value, hence cannot be let out in the atmosphere.


Liquid iron production process in the blast furnace (BF) generates gas at the furnace top which is an important by-product of the BF process. It contains certain calorific value. The top gas of the Blast Furnace is at the certain temperature and pressure exiting at the Blast Furnace top and usually contaminated with dust and water particles. This gas is also known as raw Blast Furnace gas or contaminated Blast Furnace gas. The composition and quantity of this top gas depends on the nature of the technological process in the blast furnace and the type and quality of the raw materials used for iron production in the blast furnace. In order to further use the contaminated Blast Furnace gas, it is necessary to clean it by using certain cleaning process systems which reduces outlet dust content of the solid particles and reduces the top pressure for further use in downstream process. Our Gas Cleaning Plant provides both the performance parameters i.e. reducing the dust content to less than 5 mg/Nm3 and killing the top pressure suitable for downstream process. The top gas contains carbon monoxide (CO) and is known as blast furnace gas after its cleaning. It is used as fuel gas for heating blast air in the hot blast stoves as well as supplemental fuel in the steel plant. For the BF gas to be used as fuel gas, it is necessary that the raw BF gas is cleaned with Gas Cleaning Plant and cooled to reduce gas volumes with reduction in moisture content.


Use of Gas cleaning plants for cleaning Blast Furnace gases results in substantial savings in delivery costs throughout the extensive distribution system of the steel plant.

Operation:
  • The dust-laden blast furnace gases after dust catcher are cleaned in the Gas cleaning plant. The unit is of latest design consisting of two-stage High Energy ventury Scrubbing system. The first stage ventury provides pre-cleaning of BF gases. The second stage ventury provides final cleaning of the BF gases. The system is highly efficient, and yields cleaned BF Gas. Coarse dust particles are removed in the scrubber removing 90 – 95% of the dust from the gases. Water is supplied to the scrubber through recirculation (clean) water pumps from Clarifier plant. Dust laden water is discharged through water sealing system to the launder for treatment and recycling.
  • The precleaned gases leaving after first stage ventury passes into the second stage of gas cleaning plant comprising of a high energy ventury scrubber of adjustable flaps. In the venturi throat, the gas moves against the water spray for separation of fine dust particles. The venturi throat is equipped with mechanism to adjust the throat area, which allows optimum adaptation to the gas volume generated in the blast furnace. Differential pressure across the GCP controls second stage venturi throat opening automatically. The gas leaving the second stage venturi enters the Centrifugal separator where the finest water droplets are flung against the scrubber shell and run down into the sump, and gas gets free from water particles leaving the gas cleaning plant for distribution through pipeline network to various downstream applications. In the separator, we provide highly efficient mist eliminator specially designed to reduce the outlet moisture content to less than 5%.

Construction & Operation:
  • Bag Filter is divided in three parts i.e. top part called as Plenum (Clean air chamber), which is heart of the bag filter operation; middle one is called as Housing/casing (Dirty air chamber) and bottom part is called as Hopper. The plenum is separated from the housing by the bag plate/tube sheet where the filter bags and cages (the filtering elements) are supported. The Bag Filter unit is a continuous self- cleaning dust filter, capable of removing dust particles as small as submicron size from gaseous and dust streams.
  • Bag filter construction is simple and does not have any moving parts, Pulsejet cleaning mechanism with the help of compressed air results into high dust cleaning efficiency.
  • Dust laden air enter the Bag Filter at housing under suction or pressure. The air travels through the filter bags which retains the dust particles on the surface of the bag and the clean air passes through filter bags to the plenum leading to the outlet of BF due to the suction effect created by centrifugal ID fan.
  • Dust collected on the outside of the filter bags causes an increase in the pressure differential between the dirty and clean air sides of the bag filter. To control the pressure differential across the bag filter, a sequential timer actuates a series of normally closed pulse valves at preset intervals causing them to open. A momentary rush of high-pressure air (5-7 bar g) flows from the compressed air header to the blow tube and is expelled from the blow tube through venturies at a high velocity (primary air flow). Air from each ventury induces a secondary airflow. The combined effect of the primary and induced secondary air causes an instantaneous pressure rise on the clean side of the filter bags, causing a reverse flow of air through the filter bags, thus dislodging the dust
  • Above cleaning cycle causes the dust particle to fall down in the collection hopper. Collection hopper store the collected dust temporarily. The dust is discharged from hopper bottom through RAL or Screw conveyor.

Offline Cleaning:
  • For very finer dust particles and material with lower bulk densities or with floating properties, online cleaning pulse jet bag filters are not suitable. For such type of material, offline cleaning principle is used. The Bag filter construction is compartment construction for the offline operation. Depending upon the flow rate it consists of number of chambers i.e. isolated completely with help of dampers at inlet gas line & at outlet gas line.
  • At time of the cleaning the one specific chamber is isolated i.e. Gas flow cut –off for the particular chamber with help of the damper at outlet gas line. The pulse air purging will take place at that instant in that chamber.
  • The disconnected row of filter bags is back-flushed by blow tubes located above the filter bags. For this purpose, compressed-air tanks with integrated diaphragm valves and fully enclosed solenoid valves are installed at the inlet of the blow tubes. Solenoid valves are operation in control by the timer.
  • After all the rows of filter bags are cleaned and a preset time lag. After air is pulsing done in the chamber this chamber again connected to the main gas line by opening the outlet damper, damper which is normally pneumatic operated. After that, next is compartment taken for the air pulsing & so on. Also depending on the requirement each chamber can be isolated for maintenance work by closing damper of inlet & outlet gas line.
  • Offline cleaning process beneficial for the specific applications like fine particles, low density dust, high dust load process applications etc.

For many years, the air pollution emission norms were lenient, and no major emphasis or attention was given to reduce the industrial pollution. The rising pollution levels were damaging the ecological system and human health in and around the plants. This pushed the government to enforce strict guidelines and regulations for emission limits on the industry. As a result, many industries have revamped /upgraded their existing air pollution control equipment for lower emissions.


For some of the industries, for instance cement, the pollution control equipment also acts as a product recovery system. Hence lower the emission norms, it is better for the industry as they will recover the products and increase the revenue.


Although ESP can provide lower emissions as low as < 10 mg/Nm3, but the cost to achieve the same is much higher for ESP as compared to some other solutions like a Bag Filter or a Hybrid Filter. Also, the space required to achieve the same is far more for ESP as compared to other solutions.


The existing plants (which were installed earlier with old emission norms) are also required to be upgraded / changed as per the new stricter emission norms. To do this, there are various constraints while re-designing the equipment. There are various solutions available to do so and match the current norms.

In older days, this following pollution control equipment’s were more commonly used:

  • Reverse Air Bag House (RABH)
  • Electrostatic Precipitator
  • These equipment’s have their own drawbacks and limitations.

Features:
  • Lower clean gas dust emissions compared to the ESP
  • Economical bag filter design using low pressure pulse jet cleaning in combination with bag length up to 8m can be used for ESP conversions, to decrease the pressure drop across the filter bags and can help increase the bag life time, which will lead to lower power consumption
  • Re-use of existing casing, duct work, steel support, dust transport and auxiliary equipment can help save a lot of cost.
  • Flexible and pre-assembled filter head module design reduces downtime to a minimum and enables the plant to execute ESP conversions during regular plant shutdown times
  • Since most of the dust load is taken out in the ESP Section, the cleaning requirements are reduced in the Bag Filter section leading to low compressed air consumption & longer bag life
  • Low cost solution in comparison to new installation cost.
  • This applies best for the cramped layouts where it is difficult to find space for new equipment. The plant / duct layout remains unchanged.

RTO works on the principle of thermal oxidation, decomposes hazardous gases at a high temperature and releases them into the atmosphere.


RTOs use a specially designed ceramic bed which is heated from a previous oxidation cycle to preheat the input gases to partially oxidize them. The preheated gases enter a combustion chamber that is heated by an external fuel source to reach the target oxidation temperature which is in the range of 760 °C. Temperature may be as high as 1,100 °C for applications that require maximum destruction.


RIECO-TECAM RTOs are versatile and extremely efficient – thermal efficiency can reach 95%. They are regularly used for abating solvent fumes, odors, etc. from a wide range of industries.
