Supply PH-II type modular dust filter

PH-II type modular filter dust collector is mainly composed of the box, in the box, hopper, cinder system, injection system and a control system consisting of several parts, can be a variety of intake sub-chamber structure. Flue dust from the air inlet through the lower portion of the box into the hopper; some of the larger dust particles due to inertia collision, natural subsidence and other effects directly into the hopper, the other with the air of dust rise into each bag house. After cartridge filter, the dust is retained on the outside of the filter, the filter purified gas from the interior into the box, and then through the poppet valve, the outlet into the atmosphere. Hopper dust regularly or continuously by a screw conveyor and rigid impeller unloader unloading. With the filtering process, the outside of the filter dust accompanying the increasing volume, causing the bag filter itself resistance is gradually increased. When the resistance reaches a preset value, cleaning the controller sends a signal, first make a filter chamber of the poppet valve is closed to cut off the gas flow to the chamber of the filter, and then open the electromagnetic pulse valve, compressed air from the air source order through the air bag, pulse valve nozzle on the injection tube in a very short time (0.065 to 0.085 seconds) is injected into the filter. Compressed air inside the fast-growing, so that deformation of the filter to generate high-frequency vibration, plus Shangni of a gas stream, so that deformation of the outer bag attached dust cake to fall off. After full consideration of the dust settling time (to ensure that the shedding of dust fall into the hopper effective), the poppet valve is opened, the bag house filter bag back to the state, and then enter the next room cleaning bag status, and so on until The last room is a bag cleaning cycle is completed. PH-II type modular dust filter is composed of a plurality of separate chambers, each chamber in order when cleaning separately without disturbing each other, to achieve long-term continuous operation. Said cleaning process by the cleaning timing controller or constant pressure automatic control.
