Dual-fan welding smoke absorption and purification method

Abstract

The invention discloses a dual-fan welding smoke absorption and purification method, belonging to the technical field of welding smoke treatment. The dual-fan welding smoke absorption and purification method comprises the following steps of starting a first fan and a second fan in a dual-fan welding smoke absorption purifier to enable the first fan and the second fan to perform idle operation for 5min; enabling a smoke suction cover to approach a part to be welded by adjusting an upper transmission hand wheel, a lower transmission hand wheel and a screw rod of a smoke cover, and enabling the left-and-right movement speed of the smoke suction cover to be synchronous with the welding speed by adjusting a frequency converter to control a left transmission screw rod and a right transmission screw rod; absorbing welding smoke dust through the smoke suction cover, sucking the welding smoke dust into air inlet pipes of the fans, and enabling the welding smoke dust to respectively pass through an outlet air pipe of the first fan and an outlet air pipe of the second fan to enter a back flushing device; enabling the welding smoke dust entering the back flushing device to be in contact with water after atomization, a steel wire ball and a sponge block, and absorbing smoke dust in the welding smoke dust; and enabling the welding smoke dust after the absorption of the smoke dust to pass through a gas outlet pipe and penetrate through a filter. According to the dual-fan welding smoke absorption and purification method disclosed by the invention, the welding smoke absorption and purification efficiency is greatly improved, and the suction lift is increased from 300mm in the prior art to 470mm.

Description

technical field [0001] The invention belongs to the technical field of welding fume treatment, and more specifically, the invention relates to a method for absorbing and purifying welding fume with two blowers. Background technique [0002] In boiler manufacturing industry, heavy machinery, vehicle manufacturing, shipbuilding generator set manufacturing and other fields, there are large welding workshops. In these workshops, there are generally dozens or hundreds of electric welding machines or several large-scale automatic welding equipment. When these welding machines work at the same time, the welding fume content in the workshop is very high, which seriously pollutes the air and endangers welding personnel and workers. The health of those around you. The welding methods that generate welding fume are mainly manual arc welding and gas shielded welding. In manual arc welding, the main component of the smoke generated by titanium-calcium type acid electrode and low hydrog...
