氯酸盐电解槽废气的处理

对氯酸盐电解槽废气的产生进行分析。介绍了电解槽废气处理的工艺：经过预处理，使气体中氯气含量降低50%，再经过以氢氧化钠溶液为氯气吸收剂的串联吸收塔，可使氯气体积分数达2×10^-5以下；将该气体通过以钯为催化剂、三氧化二铝为载体的除氧塔进行处理，经水环式真空泵及压缩机输送至下一工序予以利用。提出了废气处理过程中应注意的问题以及应采取的措施。

Waste gas treatment of chlorate electrolyzers

Based on the analysis about the waste gas produced from chlorate electrolyzers,waste gas treatment technology of chlorate electrolyzers was introduced as follows:firstly,content of chlorine in waste gas is reduced by 50% after pretreatment;then,volume fraction of chlorine is below 2×10-5 through the absorption columns in series,whose absorber is NaOH solution;finally,by the deoxygenization column with palladium as catalyst and Al2O3 as carrier,the gas is transported to the next procedure through water-ring vacuum pump and compressor.Some attentive problems and appropriate measures in the process of waste gas treatment were put forward.
