Abnormal problems with sodium hypochlorite purification system and solutions
In response to the abnormal problems encountered during the operation of the sodium hypochlorite purification system in acetylene production,improvement measures were taken,including a two-stage preparation process for sodium hypochlorite solution,a closed circulation cooling process for waste sodium hypochlorite,and an enhancement in the recovery efficiency of waste sodium hypochlorite.After improvement,the concentration of the prepared sodium hypochlorite solution remained stable,which ensured the purification effect of acetylene.The stripping efficiency of waste sodium hypochlorite was improved.
