We used all spent acid minus acidolysis leaching to formulate 55% acid with 98% acid. The waste acid is subjected to heat exchange through the waste heat of the calcination tail gas to improve the concentration of the waste acid, the yield of the calcination tail gas is limited, the waste acid cannot be fully concentrated, the acid concentration is lower by about 24.5%, 98% of acid consumption is higher, the proportion of the waste acid in 55% of acid is small, the waste acid cannot be fully recycled, and part of the waste acid still needs to be sent to a sewage station for neutralization, so that a double-effect concentration device is adopted to further concentrate the waste acid, the acid unit consumption of 98% of acid prepared by acid after concentration is also reduced, the proportion of the waste acid in 55% of acid is increased, the utilization rate of the waste acid is increased, and the cost is reduced.
However, the waste acid after double-effect concentration is higher in temperature, and along with the increase of the concentration of the waste acid, the solubility of impurities represented by iron is reduced, the impurities are precipitated in a solid state, the main component is ferrous monohydrate (accounting for about 62% of the total solid content), which is called ferrous flavum, concentrated acid is pumped into the next working procedure through a pipeline, a valve on the pipeline is closed after the next working procedure does not need acid, and meanwhile, the concentrated acid is notified to stop pumping, and residual concentrated acid exists in the pipeline at the moment, so Huang Yatie in the pipeline can be deposited in the pipeline to influence the normal conveying of the pipeline.
