Aluminum electrolysis cell side furnace wall repairing system

Abstract

The invention discloses an aluminum electrolysis cell side furnace wall repairing system. A first water tank connecting pipe is arranged on the left side of the top of a water tank; a second water tank connecting pipe is arranged on the right side of the top of the water tank; the second water tank connecting pipe is connected with a third pipe fitting through a second insulating hose; the third pipe fitting is connected with the inlet end above a resin filter; the left side of the resin filter is connected with the right side of a pure water tank through a fourth pipe fitting; the left side of the pure water tank is fixedly connected with a water inlet of a pipeline water pump through a first pipe fitting; a water outlet of the pipeline water pump is connected with a second pipe fitting;the left end of the second pipe fitting is connected with the right end of a first insulating hose; and the upper end of the first insulating hose is connected with the lower end of the first water tank connecting pipe. According to the aluminum electrolysis cell side furnace wall repairing system, the temperature of a heat dissipation window is reduced through a water circulation cooling method,so that the purpose of repairing a furnace wall is achieved, the structure is simple, the operation is convenient, the safety risk is reduced, and a favorable guarantee is provided for long-term stable and efficient operation of an electrolysis cell.

Description

Technical field: [0001] The invention relates to a cooling device used when the temperature of a local heat dissipation window of an electrolytic cell is too high, in particular to a side furnace side repair system of an aluminum electrolytic cell. Background technique: [0002] In the early stage of the electrolyzer start-up, a relatively good inner row of the furnace and a thicker side were formed. In the later stage of management, due to long-term operation under high temperature, strong magnetic field and other reasons, coupled with electrolyte erosion, the side side side became thinner and thinner. Severe erosion of electrolyte in individual positions will cause side silicon carbonitride bricks to corrode, resulting in high temperature and redness of side heat dissipation windows, which will have an irrelevant impact on safety production. Invention content: [0003] The technical problem to be solved by the present invention is: to overcome the deficiencies of the pri...

Problems solved by technology

[0002] In the early stage of the electrolyzer start-up, a relatively good inner row of the furnace and a thicker side were formed. In the later stage of management, due to long-term operation under high temperature, strong magnetic field and other reasons, coupled with electrolyte erosion, the side side side became thinner and thinner. Severe erosion of electrolyte in individual positions will cause corrosion of silicon carbonitride bricks on the side, resulting in high temperature and redness of the side heat dissipation window, which will have an unreasonable impact on safety production
