I. Introduction:

The mobile welding dust purifier is a kind of portable environmental protection equipment widely used for welding dust treatment in industrial welding, polishing, cutting and grinding processes. It is generally equipped with 2-3 meters long flexible suction arm, which can be flexibly fixed near the source of pollution to purify harmful dust and protect the health of staff. The backblowing system of the purifier can effectively remove the blockage of the suction arm and improve the purification efficiency. The air volume regulating valve can accurately adjust the air volume, reduce noise and save energy.

2. the working principle:

The welding waste gas is sucked into the equipment under the gravity of the fan, passes through the flame arrester of the intake vent to prevent sparks, and then enters the settling chamber. The coarse dust particles settle into the ash hopper by gravity and are collected regularly. The fine dust particles are absorbed by the filter element and further purified by the activated carbon filter layer to reach the standard and discharged into the outlet.

3. Process description:

Fan gravity suction - flame arrester stop spark - gravity settling coarse particles - filter element capture particles - activated carbon re-purification - standard gas discharge
