Low Pressure Pulse Cartridge Dust Collector

Low-pressure pulse cartridge dust collector for the international and domestic set of mature technology, very suitable for dust removal, is a low cost, stable operation, safe and feasible dust removal method, it is a kind of industry technology is mature, stable, high efficiency dust removal purification equipment, the use of pulse blowing cleaning method, has a good effect of dust removal, high purification efficiency (dust removal efficiency of ≥ 99% or more), processing gas volume, long service life of the cartridge, easy to dismantle, small maintenance workload, safe and reliable operation, covers an area of small and other advantages. Convenient, small maintenance workload, safe and reliable operation, small footprint and other advantages. Emission concentration is higher than the national emission standards, widely used in electric power coal-fired, metallurgical industry, steelmaking blast furnace raw material coal injection preparation and other factories, building materials industry, chemical industry, carbon black, asphalt concrete mixing flue gas dedusting and other industries, dust management and material recovery.

1、Working Principle

When the dust-containing air from the dust collector into the air inlet pipe into the ash hopper, and in the hopper under the action of the deflector device, large particles of dust is separated, falling directly into the ash hopper, and the finer dust uniformly into the central box and adsorption in the outer surface of the filter cartridge, filtered clean gas through the filter cartridge into the upper box, through the various off-line valve and exhaust pipe into the atmosphere. With the filtration, the dust on the filter cartridge more and more, open the electromagnetic pulse valve, blowing, blowing cleaning principle is: compressed air as the power to clear dust, the use of pulse blowing mechanism in the instantaneous release of compressed air, compressed air from the stabilized air package instantaneous through the pulse valve and the blowtorch, blowtorch holes aligned with the Venturi, close to the speed of sound to spray a primary airflow, and induced a few times the second air flow high-speed Shot into the filter cartridge, the pressure inside the bag increases, so that the filter cartridge expands sharply, relying on the impact vibration and reverse airflow will be shaken off the dust on the filter cartridge (even if the sticky fine dust can also be thoroughly cleaned) to the ash hopper, discharged by the ash discharge mechanism. When filtering high temperature flue gas, not only the dew point of the flue gas should be considered, but also the composition of the flue gas must be mastered.

2、Construction characteristics

2.1 The dust catcher mainly consists of upper box, middle box, lower box, bracket, air inlet equalization device, outlet duct cartridge and blowing device, ash discharge device and other components. The upper box is the clean gas chamber, dust collector in the upper box, when the controller opens the pulse valve, the compressed air in the gas bag will be in the 0.1 ~ 0.2s instantaneous gas into the filter cartridge, under the action of the airflow filter cartridge is subject to rapid impact and acceleration of the movement produced by the bulge and deformation, so as to remove the accumulation of dust with the surface of the filter cartridge. In the box for the dust box, equipped with filter cartridges, in the upper box and in the box between the plate separation. There are two roles of the flower plate, one is to separate the dust gas from the purified gas, and the other is to support the installation of the filter cartridge. The lower box is the ash hopper, and there is an ash unloading device under the ash hopper.
