Technological process of 32% ionic membrane caustic soda
The invention discloses a technological process of 32% ionic membrane caustic soda. The technological process comprises the following steps: removing natural organic matter impurities from brine in abrine reservoir and denitrified low-awn brine through a salt dissolving procedure; feeding a refining agent to remove some impurity ions in the process that the chemical product without impurities automatically flows through a manger, and then feeding the chemical product to a DrM filter; conveying the filtered refined brine to an ionic membrane section, and performing electrolyzing through an ionexchange membrane electrolytic tank to generate 32% finished caustic soda, hydrogen, chlorine and light salt brine; and enabling the light salt brine to be subjected to a dechlorination reaction through the dechlorination tower, entering the denitration tower to react to generate mirabilite and low-awn brine after chlorine is removed, and enabling the light salt brine remained after electrolysisto be subjected to dechlorination and denitration to generate the low-awn brine which can be reused in the salt dissolving step. Waste generated after electrolysis of the ionic membrane electrolytic tank can be recycled, the utilization rate of salty mud is increased, the salty mud is adopted for manufacturing ecological cement, and the utilization rate is effectively increased.
本发明公开了一种百分之三十二离子膜烧碱的工艺流程,包括以下步骤:将卤水库卤水和脱硝处理过的低芒盐水经化盐工序去除天然有机物杂质;去除杂质的化工品自流经过马槽过程中投放精制剂去除一些杂质离子后送至DrM过滤器;过滤后的精盐水送至离子膜工段,经离子交换膜电槽电解产生32%成品烧碱、氢气、氯气和淡盐水;淡盐水经过脱氯塔进行脱氯反应,脱出氯气后再进入脱硝塔反应生成芒硝和低芒盐水,对电解后残存的淡盐水进行脱氯脱硝后生成低芒盐水可以再次用于化盐工步。本发明可以对离子膜电槽电解后产生的废料再利用,提高对盐泥的利用率,且采用盐泥制作生态水泥,有效提高利用率。
