Abstract

本实用新型涉及一种盐电解槽，具体涉及一种零极距电解槽。提供一种降低能耗的零极距电解槽。其包括电解槽，电解槽包括离子膜(1)、阴极侧结构、阳极网(3)，阴极侧结构包括阴极网(2)，阴极网(2)做为骨架，在阴极网骨架上设有弹性构件，弹性构件为在阴极网(2)与阳极网(3)相对一侧设有的均匀分布的弹性支撑体(4)，弹性支撑体(4)为镍材质。采用上述结构以后，使得阴极网贴向阳极网，电极间的距离仅为离子膜的厚度，相应吨碱耗电降低150kwh。镍质弹性体与阴极网接触面大，压力均匀，可以将阴极网和离子膜、阳极网很好的压紧在一起。

Description

零极距电解槽
技术领域
本实用新型涉及一种盐电解槽，具体涉及一种零极距电解槽。
背景技术
食盐电解工艺高耗能，现装置为NCH即高电密自然循环复极式电解槽。电槽阴阳极间距影响着槽电压大小，间距越小，单元槽槽电压越低，相应的生产电耗就越低。长期以来电槽阴阳极之间存在着1.8～2.2mm较大的距离，这个距离从3有人考虑突破，因此长期以来就是以高耗能来实现食盐的电解。
发明内容
本实用新型的目的就是提供一种降低能耗的零极距电解槽。其技术方案是：零极距电解槽包括电解槽，电解槽包括离子膜、阴极侧结构，阴极侧结构包括阴极网、阳极网，所述的阴极网做为骨架，在阴极网骨架上设有弹性构件，弹性构件为在阴极网与阳极网相对一侧设有的均匀分布的弹性支撑体，弹性支撑体为镍材质。采用上述结构的零极距电解槽，通过以阴极网做骨架，在此基础上增加镍材质的弹性构件，使得阴极网贴向阳极网，电极间的距离仅为离子膜的厚度，与现有技术相比，电解槽阴阳极间的间距减小1.8～2.2mm，电压降为200mv，同等电流密度下零极距电解槽比普通电解槽槽电压降低180mv，相应吨碱耗电降低150kwh。镍质弹性体与阴极网接触面大，压力均匀，可以将阴极网和离子膜、阳极网很好的压紧在一起。以年产50万吨烧碱能力计算，每年可节约电能7500万度，减少二氧化碳排放量72000吨。此技术节能减排效果明显，符合目前国内氯碱行业生产的要求。
附图说明
附图为本实用新型的结构示意图；
具体实施方式
参照图零极距电解槽，包括电解槽，电解槽包括离子膜1、阴极侧结构，阴极侧结构包括阴极网2、阳极网3，阴极网做为骨架，在阴极网骨架2上设有弹性构件，弹性构件为在阴极网与阳极网相对一侧设有的均匀分布的弹性支撑体4，弹性支撑体4为镍材质。
