Dust collection device of aluminium electrolysis multifunctional overhead travelling crane

Abstract

The invention particularly relates to a dust collection device of an aluminium electrolysis multifunctional overhead travelling crane. The dust collection device of the aluminium electrolysis multifunctional overhead travelling crane comprises a telescoping pipe, a bag-type dust remover and an injector assembly, wherein the telescoping pipe communicates with a vacuum inlet of the injector throughthe bag-type dust remover; the injector assembly is provided with a jet nozzle, compressed air enters the injector assembly from the jet nozzle, and causes negative pressure around a ball sleeve, under action of atmospheric pressure, dust and air near the telescoping pipe are sucked into the bag-type dust remover, the dust falls into a dust bin under action of gravity, and the air and the compressed air are injected into an silencer sleeve through a horn throat together, and then are discharged into the atmosphere through an exhausting sleeve. According to the dust collection device of the aluminium electrolysis multifunctional overhead travelling crane, a set of negative pressure dust collection device is arranged on the overhead travelling crane, so that the dust which is raised in crustbreaking and feeding processes is collected, and the level of unorganized discharging treatment of an aluminium electrolysis workshop is raised.

Description

technical field [0001] The invention belongs to the technical field of dust collection and reuse in aluminum electrolysis production, and more specifically relates to a dust collection device of a multifunctional crane for aluminum electrolysis. Background technique [0002] The national environmental protection requirements are getting higher and higher, which puts forward treatment requirements for fugitive emissions from aluminum electrolysis workshops. The flue gas produced during the aluminum electrolysis reaction process, alumina, cryolite and fluorine salts are the main raw materials for aluminum electrolysis production. It is collected by the flue gas purification system that comes with the electrolytic cell; generally speaking, the aluminum electrolysis multifunctional crane does not have the function of collecting dust, and the dust generated by the crane during the pole change process cannot be collected by the flue gas purification system because it is far away f...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problem in the prior art that the dust generated by the crane during the pole change process cannot be collected by the flue gas purification system because it is far away from the tuyere, the purpose of the present invention is to provide a dust collecting device for the aluminum electrolysis multifunctional crane , set up a negative pressure dust collection device on the crane to collect the dust raised during shelling and blanking, and improve the treatment level of fugitive emissions in the aluminum electrolysis workshop
