Abstract
The invention discloses a single-fan welding fume absorption and purification method, belonging to the technical field of welding fume processing. The single-fan welding fume absorption and purification method comprises the following steps: starting a fan in a single-fan welding fume absorption purifier, and idling the single-fan welding fume absorption purifier for five minutes; regulating an vertical transmission hand wheel and a fume hood screw rod to enable a fume absorbing hood to be close to a to-be-welded part, and regulating a frequency converter to control the transmission speed of a transverse transmission lead screw, so as to enable the transverse moving speed of the fume absorbing hood to be synchronous with the welding speed; absorbing the fume into an air inlet pipe of the fan through the fume absorbing hood under the pressure generated by the fan, and enabling the fume to enter a back-flush device through an air outlet pipe of the fan; enabling the welding fume entering the back-flush device to contact atomized water, steel wire balls and sponge blocks, and absorbing the fume in the welding fume by the water; enabling the welding fume after being subjected to fume absorption to pass through an exhaust pipe and penetrate through the filter. According to the single-fan welding fume absorption and purification method, the welding fume can be tracked and absorbed according to the welding speed and all-directional welding requirements, and the absorption and purification efficiencies of the welding fume are greatly improved.
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 a single blower. 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 hy...
