How it works: single bag filter dust and gas through the pipeline to introduce DMC type pulse bag filter plenum imports, due to the sudden expansion of the flow channel cross-sectional area, the flow rate decreases, the gas stream part of coarse particles, the density of large dust particles under gravity, First, settling down in the hopper, those finer dust particles by inertial impaction with the bag surface, the combined effect of sieving, etc., deposited on the outer surface of the bag, the purified gas flows into the net gas from the bag interior chamber . Single bag filter characteristics: (1) has a uniform temperature, sedimentation segment, which can greatly reduce the bag load; low (2) the structure of the resistance, so that dust and stable operation at around 1500Pa; (3) air cleaning process to eliminate gas supply of oil, water condensation; (4) Light bag cage, changing bag easily; (5) to facilitate the recovery of dust. (5) internal settings bypassed flue gas temperature is too high to go directly to bypass the protection of the bag will not be burned. Single bag filter cleaning principle: single bag filter resistance value increases with an increase in the thickness of the bag surface dust surface, when the resistance reaches a certain value (1200-1700Pa), under system control, first a filter chamber shut off the valve plate, when the flow is completely cut off, pulse valve open, the pulse jet cleaning flow. Its cleaning process is sprayed into the bag through the injection device by blowing compressed air manifold on the pulse valve inside the tank, because of the role of high-speed air ejector, the pocket will form a negative pressure zone, a lot of the surrounding Gas injection lure bag, making an instant positive pressure occur within the bag, the bag this time will be the rapid expansion of air from the bag through the bag outside, so that dust deposited on the outer surface of the bag off, fall within the hopper When this room cleaning is completed, the system will automatically turn off the valve plate, and close the pulse valve, make sure the bag is not bursting, and increase life expectancy. Another filter chamber and a valve plate to close. This cycle, until all the filter chamber cleaning is completed, to achieve the purpose of cleaning. Dust collected in the hopper through the cinder valve.
