Chemical cleaning device of decomposing tank for aluminum oxide production

A decomposing tank chemical cleaning device for aluminum oxide production comprises a decomposing tank, the head portion of the decomposing tank is communicated with a chemical cleaning tank, a large circulating pump is further connected between the tail portion of the decomposing tank and the chemical cleaning tank, the chemical cleaning tank is connected with a plate heat exchanger, and a chemical cleaning pump is further connected between a liquid outlet of the chemical cleaning tank and the plate heat exchanger. The plate heat exchanger is connected with an air inlet pipe, and the other connector of the plate heat exchanger is further connected with a hot water tank corresponding to the air inlet pipe. The problems that in the prior art, scabs on the wall of the decomposing tank are difficult to clean, and the cleaning cost is high are effectively solved. 一种氧化铝生产用分解槽化学清洗装置，包括有分解槽，分解槽的首部连通有化清槽，分解槽的尾部和化清槽之间还连接有大循环泵，所述化清槽连接有板式换热器，化清槽的出液口和板式换热器之间还连接有化清泵，所述板式换热器连接有进气管，板式换热器的另一接口还连接有和进气管相对应的热水槽有效的解决了现有技术中的分解槽槽壁
