Sieve pore is will not pass through in the grain size object of slot size, the final screening for realizing fluid.It is more than 1 in certain industrial wastewater if you need to remove
μm particulate matter, the industrial wastewater that pressurizes enters screening plant, and the size that sieve pore is arranged is 1 μm, then is more than 1 μm of particulate matter not
It then can be screened out by sieve pore with water by sieve pore, particulate matter of the gained less than 1 μm.
s4:The sieve pore is flowed counterflow through using cleaning fluid, to remove or recycle the particle for being jammed in the sieve pore;Screening
After a certain period of time, fail to be blocked in by the grain size object of sieve pore being greater than the set value on the outside of sieve pore, at this moment can utilize cleaning stream
Body flows counterflow through sieve pore, and (forward direction herein refers to that fluid stream to be sieved crosses the direction of sieve pore, and direction in contrast is anti-
To), wherein cleaning fluid passes through special selection, is easy to detach with the grain size object less than setting value filtered, will not be made to it
At secondary pollution, as using cheap and chemically stable nitrogen to the particle for being more than 1 μm that is jammed in described in s3 on the outside of sieve pore
Object is then more than 1 μm of particulate matter and is flowed out from cleaning fluid outlet 2 together with nitrogen and a small amount of industrial wastewater into horizontal high voltage back scrubbing, and
