Reverse pulse jet bag filter means opposite the filter bag after blowings net flow direction, net gas discharged from the upper part of the net gas tank. Depending on the injection pressure, reverse pulse jet bag filter can be divided into low-pressure reverse pulse jet bag filter (LNDM) two kinds. (A) construct an inverse pulse jet baghouse filter chamber consists of net gas chamber, pulse-jet device and ash hopper means. (B) works by dusty gas inlet into the hopper, large particles fall into the hopper, fine dust into the air filter chamber, after filtration through bag, venturi scrubber into the net scriptures have vented the gas chamber, with the filtering performed, resistance increases, when the time reaches 1.2 ~ 1.5kpa and began cleaning. When cleaning a regular order by the control device to trigger the solenoid valve, pulse valve open, so that the compressed air within the air bag is ejected from the injection tube perforations (primary air), scripture several times a venturi-induced wind ambient air (secondary wind) into the bag, so that the rapid expansion of the bag in an instant, and is accompanied by a reverse effect this flow, shake off the dust. (C) works blowing low pressure injection system principle is: Under normal circumstances, the corrugated diaphragm seal the outlet A pulse valve control device when no signal output, throttle pressure and the gas chamber has equal pressure package pulse valve is turned off: When the controller sends a signal, the control valve is open, the pulse valve back pressure chamber B with the same atmosphere (relief): corrugated diaphragm moves to the left, pulse valve is opened, the compressed air flow injection tube, subsonic jet nozzle, so as to achieve the purpose of cleaning. High-pressure injection system works is: a termination compressed air pulse valve bag, pipe the other end of the injection pulse valve back pressure chamber on pulse valve, pulse valve operation is completed by the control device. When no signal output control device, the solenoid valve of the movable core (porosity analyzer as baffles) to seal the exhaust port, the impulse valve is in the closed condition, when the control device sends a signal, the pulse solenoid valve and the back pressure chamber the atmosphere (relief), pulse valve is open, compressed air from the air bag through the pulse valve through the injection tube holes sprayed into the venturi tube, resulting in a positive pressure within the bag along to achieve cleaning. Impulse control instrument commonly used in China are: non-contact electric pulse controller, pneumatic and mechanical pulse controller pulse controller, the corresponding control valve: solenoid valves, pneumatic valves and machine control valve.
