Abstract:In the flue gas purification system of aluminium electrolysis, the operation stability of the equipment is closely related to the electrolytic flue gas purification efficiency, and under the same conditions, the more stable the operation of the equipment, the higher the electrolytic flue gas purification efficiency will be. In this paper, a device that can effectively solve the problem of smoke pipe slag removal in aluminium electrolytic purification system is proposed, which has the characteristics of increasing flue gas flow, improving equipment operation stability, reducing equipment failure, reducing maintenance cost and prolonging the service life of equipment, so that the flue gas purification efficiency has been effectively guaranteed, the environmental protection technical indicators have been improved, and the energy consumption of system operation has been reduced. It provides a new idea and method for the slag removal of aluminium electrolytic smoke pipes.
