INTRODUCTION

The selfcleaning type air filter is fitted before air inlet pipe of air compressor completed for air separation plant. The domesticmade cartridge has low service life, and in case of highly wet air the filter paper is liable to stick, which lowers the filtering efficiency, results in frequent repair of air compressor repair, an seriously impairs prolonged stable run of air separation plant. The service life of cartridge of selfcleaning type air filter is extended and the filtering efficiency is improved through use of the nonwoven filtering carton blended with compound fiber. The cartridge made of compound fiber, and the imported filter paper, adjustment of its programmable controller and change of its backblowing pressure and air supply.

WORKING PRINCIPLE

Filtrating process: JKLQ can absorb ambient air of surrounding under the effect of compressor suction negative pressure. Dust will be block the outside surface of the filter cartridge as gravity, static, contact when air through the efficient filter cartridge. Purified air go in the clean room and out from out air hose.
Selfcleaning process: Solenoid valve stare and drive disk valve, when computer give orders. it can release stream pressure with 0. 40. 6 MPa pulse airflow at moment. The selfcleaning process is over , when the pulse airflow is rectifying erupt by dedicated shower nozzle.
There are three methods to control the process:

First , fixed position and time, The appropriative PTG can set the spacing interval and selfcleaning time at will.

Second , differential pressure and selfcleaning , the PTG can automatic continuous selfcleaning when the differential pressure overtake index .

Third: manually selfcleaning. when the PTG can not work or more dust , it can use manually selfcleaning.

FEATURE

1. filtration core—air filter element use special lining structure and doubledeck filtrating structure , it greatly increase filtrating area than old structure .
2. machinery mechanotronics , can come true selfcleaning to air filtration and filter element . can unmanned operation .
3. filter frame use module devise , can flexible combination according to the customers’ requirement . convenient handing and installation .
4. simple structure , the quality of equipment is light , is only for bag filter and other filters 1/31/2.
5. counter blowing system shutdown parts (pressure difference transmitter , pulse electromagnetic valve , PLC , etc ) are imported components .
6. counter blowing low gas consumption, generally equal to 0. 10. 3m3/min, pressure is 0. 40. 6 MPa
7. Low maintenance workload, except change regularly air filter canister outside, daily maintenance basic to zero, need not change filter canister , because will no stop operation , that would affect your work safeguard filter.
8. Based on user needs , increase dust recovery function.
