The integral ventilation displacement dust removal is to use the characteristics of welding fume suspended above 4-8 meters due to thermal rise and gravity. The suction pipe is installed on the column about 4-5 meters high on one side of the workshop. Two layers of air suction outlets are set on the pipeline. The wind power of the dust collector is used to effectively collect the dust floating on the upper part of the workshop. The air outlet is set on the dust removal pipe on the other side of the workshop, and the qualified air discharged by the dust collector is used as the air supply to speed up the air flow and make the welding dust flow to the suction outlet.
