At present, two measures are adopted in many related industries: 1. the air valve connecting pipe is directly discharged to a dust removal bin through scattering; 2, filtering directly by using a cloth bag.

In the process of exhausting the air valve, the air pressure is not very difficult to blow dust into the closed dust removal bin, and the dust removal bin is very easy to block for a long time. Because the original dress of the air valve directly is used in succession with the dust removal storehouse for a long time and causes the jam later stage to demolish the connecting pipe and utilize the dust removal sack to filter the exhaust, sometimes the too big sack of pressure jumps and damages and cause the smoke and dust to spill and cause dust pollution, and is frequent to the sack change, and the dust is extremely easy in the sack to cause the influence to the air valve exhaust to influence the normal operating of air supply, because the air valve is extremely easy to appear the potential safety hazard about the personnel at the air supply tank top often.
