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.

Electrostatic precipitator (ESP) 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:

1. 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..

2. 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
