Series filter bag type ultrasonic water mist laminating welding fume purification equipment

A series filter bag type ultrasonic water mist laminating welding fume purification device comprises a shell, a plurality of dust removal and purification assemblies are arranged in the shell, an air inlet is formed in the lower portion of the shell, each dust removal and purification assembly comprises a plurality of cloth bags at the bottom, and an ultrasonic atomizer is arranged on the lower portion of the inner side of the shell; each dust removal and purification assembly comprises a pulse air generator capable of emitting pulse air, a suction fan used for sucking air and a control valve used for controlling the pulse air generator and the suction fan to be alternately connected with the cloth bag. The utility model effectively solves the problem that when the existing negative pressure suction equipment collects and purifies welding fume, finer solid particles such as iron oxide, silicon oxide, copper oxide and manganese oxide smaller than 2.5 microns in the welding fume are difficult to collect and pur
