Introduction

The resistance of filter cartridge filter as the filter material increases with increasing the thickness of the surface dust, resistance to a specified value, the clear ash, pulse control meter control pulse valve open/close at this time, when the pulse valve opens, the gas bags of compressed air through the pulse valve through the holes on the spray torch, jet ejector flow out of a high speed and high pressure, thus forming a equivalent of ejector flow volume 1 to 2 times the airflow, together into the cartridge, cartridge makes a momentary positive pressure and ballooning and micro, the dust deposited on the filter material loss, falling into the hopper, the dust collected in the hopper through the discharge valve, the continuous eduction.
