Bag Filters Dealers in Howrah

The Pulse Jet Bag Filters are used to clean dust laden gases emitted from process equipment of material handling, grinding mills, etc. These Pulse Jet Bag Filters are widely used in utility boilers, cement, steel, sugar, chemical and pulp and paper industries. We manufacture Pulse Jet Bag Filters which act as an economic mode of a dust collection for various operations. These are simple in design with no internal moving part. They offer travel free operation with compress air jet cleaning. Their method of clinging operation at higher filter rates resulting in compact units occupies less floor space. Sizing Of Pulse Jet Bag Filters : The Pulse Jet Bag Filters are sized and designed to maintain a suitable air to cloth ratio depending on the application. Multi module Pulse Jet Bag Filters are manufactured with properly designed inlet and outlet plenums for even gas distribution across all the modules. Inlet Choice : Our collector design is offered either in top entry or hopper entry to meet the needs of your applications. For fine dust (such as talc) applications with low dust concentrations and with higher air-to-fabric ratios, top entry is more suitable. Top entry generates a down flow of air throughout the collector, due to which it aids the movement of particles towards the hopper. In case of course dust (such as sand, etc.) and high dust loads, hopper entry is preferred. Heavy particles naturally gravitate to the hopper. Pulse Jet Cleaning : The Pulse Jet Bag Filters in the collector are continuously cleaned with pulses of compressed air which are initiated by an electronic sequential timer. Small volumes of high pressure compressed air are directed from a reservoir tank through solenoid valves and nozzles. As the burst of air passes through the venturi at the top of each bag, it induces a larger volume of additional air into the clean face side of the bag, inflating the fabric bag and breaking the dust layer on the outer face of the bag. The fabric gets a secondary cleaning as the pulse bounces back up the bag. The cleaning provides an effective means of reconditioning the fabric without interrupting the normal airflow through the filter system. Since the pulse-jet collectors operate at higher filtering velocities than the corresponding fabric collectors which are cleaned either by mechanical shaking or low pressure reverse air. Convenient Bag Removal : In most of the conventional bag filter systems, filter bags are removed from the top side, which means first the top assembly, including venturies, etc., has to be opened or dismantled, and then each bag has to be lifted up. The operation requires several persons working for several days. Moreover, the user has to ensure that the height of the ceiling should be at least double the height of the bag filter system. Bag filters are designed in such a way that the bags can be removed from the side panels of the collector, without having to dismantle any part, which means that the bags can be removed by a single person in a matter of a few minutes. Pressure-Drop across the Collector : Since the bags are continuously cleaned, the pressure drop is very low and almost constant. Though the pressure drop will depend upon factors like air-to-fabric ratio, temperature of air, dust loading, fines of dust, etc., normally it will range between 75 to 150 mm WG. Compressed Air Requirement : Our Bag filter collectors are designed for optimal use of compressed air for bag cleaning. The actual air consumption will depend upon various parameters of the final applications, such as dust loading, air-to-fabric ratio, type of filter media used, etc. Material Used For Construction : The standard material used for the construction of our collectors is CRC mild steel treated for rust prevention, double coated with red oxide primer and painted in color of your choice. Special materials of construction, like, SS, PVC, FRP, etc. can be used to meet the application requirements. Support Structure : The system is built with self-supporting strong structure out of steel sections. The ground clearance under the hopper outlet flange, as a standard is kept at 1200 mm, though it can be designed to provide any clearance as per your requirements. Filter Media : For general applications heavyweight "Non-woven, needled, felt media" is used for high collection efficiency and long life. Felts with special surface finishes to suit physical and chemical nature of the dust to be handled and humidity and temperature of the air are also available.

Specifications: offers better & safe working conditions for employees reduces maintenance of other machinery maintains cleanliness helps in adhering to regulatory requirement for waste control high efficiency with effective waste control features: durability resistant against corrosion accurate dimensions.

RRK ENGINEERING PVT. LTD. Is a single window solution for your air pollution controlling needs. It means we can supply also all spares parts for your Air Pollution Control Equipment.Pulse Jet Bag Filter: Pulse Jet is a new era in the field of bag filter, pulse jet fabric filter is after improvement over various designs available in the market. The double bead snap band fitting arrangement ensures perfect sealing between raw gas and clean air chambers. Self supporting cages with best fit between bag and cage enhance filter life and reduce the pressure on the fabric. We use double diaphragm type pulse valves which give excellent performance and effective cleaning of filter bags. These are notable features of the generation fabric filter are as under:• A Compact assembled Unit• Shorter bag change out time due to unique design of bag and cage tops and manifold pipe fitting.• Lower operating pressure drop due to use of most suitable fabric media and best cage and bag fit.• Lower compressed air consumption.• Extensive field information used for selecting the best media for a given applications.• Low investments and maintenance cost is minimum.• Low compressed air consumption with high bag Cleaning efficiency.• Low power consumption combined with high filtration efficiency.• Minimum Pressure drop in the bag cleaning system.• Filter bag replacement is simple.
