PULSE JET BAG FILTER

Dust Laden air enters the dust collector through the hopper or high –entry inlet housing section An internal baffle distributes the dirty air within, the housing ,so as to reduce air velocity and allow heavier particles drop into hopper, while lighter particle collects on the outside surface of the bags

For operation of bag filters, suction hoods shall be connected to suction take off points. These suction take off points shall be connected to the main ducting by branch ducting and the other end of main ducting shall culminate into bag filters. The outlet of bag filter to inlet duct of blower and the same will exhaust clean air to atmosphere vide a stack.

Cartridge dust collectors , cassette type bag filter

Cartridge collectors use perforated metal cartridges that contain a pleated, nonwoven filtering media. The pleated design allows for a greater total filtering surface area than in a conventional bag of the same diameter, The greater filtering area results in a reduced air to media ratio, pressure drop and also overall collector size. Cartridge collectors are available in single use or continuous duty designs. In single-use collectors, the dirty cartridges are changed and collected dirt is removed while the collector is off. In the continuous duty design, the cartridges are cleaned by the conventional pulse-jet cleaning system. In cassete type rectangular filter bags are used.

Insertable bag filter

Insertable Bag Filters are suitable for direct mounting for bin vent, belt transfer point, bag-dump, mixer ventilation applications etc. The dust laden air is drawn on to the rectangular filter pads where dust is retained on the outside of the fabric. The pad is cleaned by reverse compressed air pulse. The Insertable Bag Filter offered by us does not require any hoppers, ducting, structural supports, etc. The Insertable Bag Filter

Cyclonic bag filter

BAG FILTER FOR BOILERS
Bag Filter is offered for filtering the exhaust fumes from the boiler. Boiler fumes are normally at high temperature, therefore, complete system, bag filter, centrifugal fan etc are designed for high temperature application. The bag filter are specifically designed for the particular boiler,

As per temperature, gas composition and fuel used, bag filter and fan is specifically designed

For a particular project site separately. Bag Filter can operate at a temperature of 140 – 250 Deg C, we select the fabric of filter bags accordingly. We also analyze the fuel used in the boiler and subsequently decide on various specification of the bag filter. Fan is also designed specifically for high temperature applications and for the specific project.

If required, as per project site application, we also supply cyclone / multicylone to safeguard the Bag filter from getting unburned spark particle from the boiler and at the same time, it reduces the dust load on the bag filter.
Bag filter
Bag filter comprises of the dust collecting hoppers, casing , top plates, from which bags and cages will be put up, Heavy duty rotary Air locks, Discharge chute etc. Bag filter will be dully supported on foundation and adequate support structure shall be considered for the same, as per load datas.

The bag-filter shall be of pulse jet type having tubular sleeves and bags is arranged in a rectangular matrix. These bag sleeves contain cylinder cages inside to prevent them from collapsing. The dust laden air is drawn through sleeves by an externally connected centrifugal fan and during this process dust gets accumulated on the outside surface of the bag sleeves . These bag sleeves are periodically cleaned by short blast of compressed air ( Pulse- Jet ) directed downwards through venturies at the top of sleeves . These blast are in direction opposite to the flow of dust laden air. This reverse flow of compressed air flows the fabric bags away from the cages and loosens the dust collected on the bags . This process is initiated for each rows of bags.

Dust get collected on the surface of the filter media and eventually forms a thick cake. When a pulse of compressed air is injected into the filter element a shock wave is induced that causes the dust cake to break away. Some of this air will pass through the filter media in a reverse direction and further separate the dust cake from it. The name “Reverse Pulse Jet” is derived from this cleaning method. Separated dust falls into the hopper where it is removed through an airlock or other airtight device. The airlock has a very important function of preventing air from entering the hopper through its discharge. Leakage at the hopper’s discharge will cause re-entrainment of dust onto the filter elements. which could contribute to high differential pressures.

SIDE HOOD SUCTION BASED BAG FILTER FOR INDUCTION FURCACES
Fume extraction systems is provided to capture the dust from the fumes generated from induction furnace,

For capture of dust from the fumes generated, side/top suction hoods has to be installed at suitable locations at induction furnace.. The dusty air is being sucked and then cleaned in pulse jet type bag filters before discharging cleaned air to atmosphere through fan and chimney/ exhaust duct, etc.

The dust/fume extraction systems essentially comprise suction hoods, ducting, pulse jet type bag filter, centrifugal fan, MCC panel and chimney /stack
