MS Dust Extraction System Bag Filter, For Industri:

Product Description

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.
