Smoke exhaust and dust removal device for electrometallurgical furnace

Abstract

The invention relates to the technical field of electrometallurgical furnaces, and discloses a smoke exhaust and dust removal device for an electrometallurgical furnace. The device comprises a treatment cylinder with a cylindrical structure, a smoke suction pump is fixedly mounted on the outer cylinder wall of the treatment cylinder through a rack, the input end of the smoke suction pump is fixedly communicated with a smoke suction pipe, and the output end of the smoke suction pump is fixedly communicated with a smoke exhaust pipe; the smoke exhaust pipe penetrates through the side wall of thetreatment barrel and extends into an inner cavity of the treatment barrel, a matched first filter screen is fixedly installed in the treatment barrel and located above the smoke exhaust pipe, a second filter screen matched with the treatment barrel is arranged below the smoke exhaust pipe, and the second filter screen is obliquely arranged; a blow-off pipe is fixedly communicated with the position, corresponding to the lower end of the second filter screen, of the side wall of the treatment cylinder, and a matched sealing cover is in threaded connection with a pipe opening of the blow-off pipe. According to the smoke discharging and dust removing device for the electric metallurgical furnace, efficient dust removing can be conveniently conducted, smoke can be conveniently neutralized, andthe situation that the smoke is directly discharged and pollutes the environment is avoided.

Description

technical field [0001] The invention relates to the technical field of electric metallurgical furnaces, in particular to a smoke exhaust and dust removal device for electric metallurgical furnaces. Background technique [0002] Electrometallurgy refers to the metallurgical process of extracting, recycling and refining metals from ores or other raw materials using electrical energy. Including electric furnace smelting, molten salt electrolysis and aqueous solution electrolysis, etc. The prerequisite for electrometallurgy to become large-scale industrial production is the abundant supply of cheap electrical energy. The adoption of electrometallurgical methods, especially electric arc furnace steelmaking and molten salt electrolytic aluminum smelting, is a major advancement in modern metallurgical technology. [0003] A large amount of flue gas and dust are produced during the production of electrometallurgical furnaces. In the prior art, a fume hood is added to the furnace c...
