摘　　要：自贡鸿鹤化工股份有限公司离子膜烧碱工程氯氢处理过程中,氯气洗涤单元氯水低位密封槽多次出现筒体与封头连接处塑料焊接损坏的情况。经过理论计算,将氯气洗涤塔和低位密封槽相连接的溢流管高度由1600mm改为800mm,避免了塑料焊接的损坏,且保证氯水循环泵不会出现掉液。In the process of chlorine treatment process of ion-exchange membrane caustic soda project of Zigong Honghe Chemical Industry Co.,Ltd.,the low-position seal tank of chorine water from chlorine washing unit exhibits damage of plastic welding between the head and the shell for many times.Through the theoretical calculation,the height of the overflow pipe joined chlorine washing tower with the low-position seal tank is reduced from 1 600 mm to 800 mm so as to avoid the plastic welding portion from demaging and the chlorine water circulating pump from leaking.
