Pulse self cleaning air filter

Product Introduction

Pulse self cleaning air filter is a new type of high efficiency air filter with automatic dust cleaning function, especially suitable for long-term, continuous air purification of gas equipment in sandstorm prone conditions.

Automatic control, safe and reliable work. The equipment is suitable for supporting use with large and medium-sized gas turbines, high-power diesel engines, oxygen generators, large air conditioners, blower and other large air volume, especially suitable for supporting or technical transformation of gas equipment in the environment of high dust concentration and strict air purification index.

Principle of Operation

In the process of air filtration, due to the adsorption of dust, the internal and external pressure difference of the air flow through the high efficiency filter element will gradually increase. When the internal and external pressure difference of the filter element is greater than a certain value, the "pulse controller" is automatically started. It controls the "pulse valve" in a very short time to carry out the pulse backwashing program from inside to outside to each row filter element with compressed air. 

To remove the dust adsorbed on the filter element; When the filter element is washed clean (that is, the internal and external pressure difference is less than a certain set value or after several cycles of backwashing), the washing process and self-stop. Because the compressed air backwashing is ejected to the filter element through the "Venturi tube", it not only consumes little gas, but also has strong explosive power and good flushing effect. Pulse cleaning basically does not affect the normal operation of gas equipment.

Filtration process

Dusty air through the air compressor suction, from the primary coarse filter box (1) inhalation, through the high efficiency filter cylinder (2), due to gravity inertia, diffusion, contact retention and other comprehensive effects, the dust is adsorbed on the high efficiency filter cylinder, clean air through the seal gasket (3) into the Wenner tube (4), to the net gas chamber (5) to meet the air collection port (6), and then from the net gas outlet pipe (7) by air compressor inhalation.
