Description
技术领域
本发明涉及一种广泛应用于食品工业、日用化工行业、医药行业及各类工业污水、工业循环水、饮用水、医院污水、生活污水的杀菌消毒、灭藻、脱色、除味、降低COD、BOD指标以及造纸、纺织工业漂白等方面的电解法二氧化氯复合消毒剂发生器。
背景技术
CN200420069271.4公开了本公司的二氧化氯复合消毒剂发生器,包括浓盐水进口、过滤器、软化器、由阳极、阴极组成的电解槽、冷却水进出口、排液口，其在阳极和阴极之间设有石英微孔渗透膜。电解槽结构为单面单极式,其阳极、阴极之间采用的是石英隔膜。其冷却水进出口设在阳极中心管内。
这种结构的缺点是：(1)只有阳极和阴极且它们之间设有的是石英微孔渗透膜；这种结构的导电率、微孔径均仍不太理想；造成盐耗、电耗、产ClO2效率也还不太理想；(2)石英隔膜的极耐腐蚀性能不太理想，造成阳极的使用寿命不太长，有时会结垢、故障率仍较高。(3)该电解槽结构为单极单面管式结构,阳极电解面积相对较小,产生的ClO3 -的含量很低。(3)冷却水进出口设在阳极中心管内，造成冷却效果不太理想，温度难以控制。(4)阴极为普通的钛材不利于H2的生成。由于CN200420069271.4所述电解槽结构形式的局限造成了ClO2浓度低下，ClO2浓度只有8-12％。
发明内容
本发明的目的在于提供一种故障率低、使用寿命长、电解效率高、能同时产生ClO2、Cl2、O3、O2、H2O2的电解法二氧化氯复合消毒剂发生器。
本发明的技术方案是：包括化盐器、自动软化机、精密过滤器、由阳极和阴极组成的槽式电解槽、冷却水进口、浓盐水进口、二氧化氯复合消毒剂出口；其特征在于；所述电解槽为双面复极式结构，其阳极与阴极之间装有中间电极，在阳极与中间电极之间装有PTF网孔隔膜，在中间电极与阴极之间装有PTFE微孔渗透电解隔膜。
所述阴极是涂有催化作用材料镍、钴氧化物涂层的网状催化阴极，所述网状催化阴极为同电位夹层结构。具有良好的冷却效果。
所述阳极为钌、铱、钯多元氧化物涂层的网状活性阳极。
所述中间电极为铱钛电极。
所述活性阳极、催化阴极、中间电极、PTF网孔隔膜、和PTFE微孔渗透膜为矩形筒式安装。
在实际工作中可以根据不同的要求设计成不同的型号。
本发明的优点：(1)设计了带有中间电极的电解槽为双面复极式结构并采用了PTFE优质的微孔渗透电解隔膜，这种结构具有极高的导电率、微孔径和极耐腐蚀的特点。使得本设备在盐耗、电耗、产ClO2效率等方面有了很大的提高。(2)采用PTFE微孔渗透隔膜，相对于石棉隔膜或离子膜隔膜而言，使用长时间后几乎无腐蚀，经实实验明阳极的使用寿命可提高十倍以上，电解时不会结垢、故障低。且电极超薄、极间距很小、节能，使用条件易于控制、维护保养也方便，故很容易使产品产业化生产。(3)活性阳极、中间电极、催化阴极采用矩形筒式安装，冷却水进出口均设在阴极室内，冷却效果好、电解效率大大提高，电流效率可大于95％，由于碱液循环利用,所以盐利用率可达95％以上；ClO2含量提高到35％以上，氯气和其它消毒性气体占65％，大大提高了消毒、氧化效果，运行成本低。
附图说明
图1为实施例1电解槽结构原理图；
图2为实施例1电解槽装配图；
图3为实施例1的二氧化氯复合消毒剂发生器外部结构示意图。
具体实施方式
以下结合附图和实施例对本发明作进一步说明：
实施例：
参照附图1：
本实施例的电解槽是电解槽为双面复极式结构，其中间是钌、铱、钯等多元涂层的网状活性阳极1-1，两侧是涂有催化作用材料镍、钴氧化物涂层的网状催化阴极1-2，所述催化阴极为同电位夹层结构。在活性阳极1-1与催化阴极1-2之间装有中间电极1-3，在活性阳极1-1与中间电极1-3之间装有PTF网孔隔膜1-4，在中间电极1-3与两侧的催化阴极1-2之间装有PTFE微孔渗透电解隔膜1-5。
参照附图2：
电解槽装配时，其活性阳极1-1、催化阴极1-2、中间电极1-3、和PTFE微孔渗透膜1-5均为矩形筒式安装；在其上端设有电解槽上封盖1-6，其下端设有电解槽下封盖1-7。
参照附图3：
将电解槽1、化盐器2、自动软化机3、精密过滤器4、冷水进口5、浓盐水进口6、机架7，流量计8组装成二氧化氯复合消毒剂发生器。
使用时，通过直接电解食盐并自动催化循环制备二氧化氯复合消毒剂。食盐在水中电离形成Na﹢和Cl﹣及水分子电离成H﹢、OH﹣发生一系列的电化学反应，在电解槽中阳极室产生ClO2、Cl2、O2、O3、H2O2等多种强氧化剂形成了独特的协同作用(其中ClO235％左右，Cl260％左右，O2占3％左右，O3、H2O2占2％左右)，其消毒杀菌能力优于任何一种单组份的消毒剂。该混合气不仅具备ClO2消毒的优点，同时由于多种混合成分的协同作用，使混合气体的杀菌速度更快，杀菌更广谱，效果更佳。通过负压吸收管路投入到待处理水中达到消毒杀菌的目的。
各种不同型号的产品的工艺参数如表1所示
