本公开一实施例提供低盐EOW电解槽100，如图1至图4所示，低盐EOW电解槽100包括槽体10、无极性隔膜40、阴极20以及阳极30，槽体10设有腔体，无极性隔膜40位于腔体内，并将腔体分隔形成阴极腔15和阳极腔16，槽体10上开设有与阴极腔15连通的第一进液口131及第一出液口132，且槽体10上还开设有与阳极腔16连通的第二进液口141及第二出液口142，第一 进液口131及第二进液口141用于注入电解液，第一出液口132及第二出液口142用于流出电解后的液体，阴极20位于阴极腔15内，阳极30位于阳极腔16内。
在某些实施方案中，低盐EOW电解装置的电解槽100，包括槽体10、无极性隔膜40、阴极20以及阳极30，无极性隔膜40将槽体10内的腔体分隔形成阴极腔15和阳极腔16，且槽体10上开设有与阴极腔15连通的第一进液口131及与阳极腔16连通的第二进液口141，在制备EOW时，可将电解液分别注入至阴极腔15内和阳极腔16内，阴极腔15内的阴极20和阳极腔16内的阳极30发生电解反应，且在阳极腔16内生成EOW，阴极腔15内生成碱性电位水，然后阳极腔16内的EOW可由第二出液口142流出，阴极腔15内的碱性电位水可由第一出液口132流出。通过设置无极性隔膜40，只有离子可以通过，而水和其它杂质无法通过，并且采用无极性隔膜40，电解时，在电场的作用下，阴极腔15内的阴离子通过无极性隔膜40向阳极腔16移动，并在阳极腔16内生成EOW，阳极腔16内的金属阳离子通过无极性隔膜40向阴极腔15移动，这样阳极腔16内的金属阳离子残留量较少，即生成的EOW中金属阳离子残留量较少，实现低盐EOW的制备，保证制备的EOW良好的杀菌效果。
在某些实施方案中，槽体10包括第一槽体11及第二槽体12，第一槽体11与第二槽体12装配连接，无极性隔膜40固定在第一槽体11与第二槽体12之间，第一槽体11具有第一镂空部，第二槽体12具有第二镂空部，第一镂空部及第二镂空部均分布有交错设置的多个阻挡条。通过设置第一槽体11和第二槽体12，可以通过第一槽体11和第二槽体12的装配连接实现无极性隔膜40的固定，固定方式简单。而且，该无极性隔膜40固定在第一镂空部与第二镂空部之间，通过纵横交错设置的多个阻挡条可以为无极性隔膜40提供一定的支撑，使得无极性隔膜40受力均匀，有效减小无极性隔膜40破裂的几率，延长无极性隔膜40的使用寿命，并且还使得无极性隔膜40露出，以便进行离子交换。另外，该结 构设置形式，可以装配面积相对较大的无极性隔膜40，使阴阳离子顺利通过，加快EOW的制备效率。当然，在其他实施方案中，无极性隔膜40也可以通过其他方式进行固定，或者也可以直接放置在槽体10内。
在某些实施方案中，槽体10还包括第三槽体13及第四槽体14，第三槽体13与第一槽体11装配连接，并形成阴极腔15，第四槽体14与第二槽体12装配连接，并形成阳极腔16。在某些实施方案中，第一槽体11还具有第一框体部，第一镂空部位于第一框体部的框内，第二槽体12还具有第二框体部，第二镂空部位于第二框体部的框内，且第一镂空部与第二镂空部固定无极性隔膜40的面分别与第一框体部及第二框体部平齐，与该面相对的面凹陷于第一框体部及第二框体部，第三槽体13及第四槽体14均在中部开设有凹槽，第一槽体11与第三槽体13装配连接后，第一槽体11的凹陷部分与第三槽体13的凹槽部分形成整个阴极腔15，同样地，第二槽体12的凹陷部分与第四槽体14的凹槽部分形成整个阳极腔16。这样，可以为电解液提供一可注入的空间，整体结构比较简单，易于装配。另外，还考虑到便于生产加工、装配及美观性的问题，第一槽体11和第二槽体12结构相同，第三槽体13和第四槽体14结构相同，且第一槽体11、第二槽体12、第三槽体13及第四槽体14均呈板状。当然，在其他实施方案中，也可以第三槽体13与第四槽体14围合形成腔体，第一槽体11、第二槽体12及无极性隔膜40整体位于腔体内，并将腔体分隔形成阴极腔15和阳极腔16。
在某些实施方案中，阴极20与无极性隔膜40分别设置在第一镂空部相对的两侧，并均与第一镂空部抵接，阳极30与无极性隔膜40分别设置在第二镂空部相对的两侧，并均与第二镂空部抵接。如此，阴极20和阳极30两级之间的间距为第一镂空部的厚度、第二镂空部的厚度及无极性隔膜40的厚度之和，两级间距较小，电解效率高。在某些实施方案中，第一槽体11及第三槽体13上分别开设有供阴极20和阳极30的阴线穿过的电极孔，以便与 电源电性连接，通过电源进行供电，保证整个电解反应的顺利进行，且两个电极孔处均进行密封处理，避免漏液。
在某些实施方案中，第三槽体13的内侧壁上具有第一凸起133，通过第一凸起133将阴极20压紧在第一槽体11上，第四槽体14的内壁上具有第二凸起143，通过第二凸起143将阳极30压紧在第二槽体12上。在某些实施方案中，第三槽体13朝向靠近阴极20的一侧均匀形成有多个第一凸起133，第四槽体14朝向靠近阳极30的一侧均匀形成有多个第二凸起143，且第一凸起133紧贴第三槽体13凹槽的侧壁，自第三槽体13凹槽的底壁延伸至阴极20所在位置，第二凸起143紧贴第四槽体14凹槽的侧壁，自第四槽体14凹槽的底壁延伸至阳极30所在位置，以实现压紧阴极20和阳极30。通过形成有第一凸起133及第二凸起143，进而可分别将阴极20及阳极30压住，从而阴极20和阳极30之间的两级间距固定为只有第一镂空部的厚度、第二镂空部的厚度及无极性隔膜40的厚度之和，两级间距很小，进一步提高了电解效率，其中，第一镂空部的厚度和第二镂空部的厚度均为0.5mm，阴极20和阳极30之间的两级间距固定为只有1mm加上无极性隔膜40的厚度，且无极性隔膜40的厚度也非常薄，使两级间距很小。另外，通过直接形成凸起的方式来压紧阴极20和阳极30，结构及方式均比较简单。当然，在其他实施方案中，压紧的结构不限于此方式，也可以通过直接在第一槽体11和第二槽体12上分别开设固定槽或者形成固定卡沿将阴极20和阳极30直接固定，或者也可以在阴极腔15或阳极腔16内分别设置第三压紧件，分别将阴极20和阳极30压紧在第一槽体11或者第二槽体12上。
在某些实施方案中，阴极20呈板状，且阴极20上分布有网孔，阳极30呈板状，且阳极30上分布有网孔。在某些实施方案中，阴极20及阳极30均呈长方体板状，并分别具有与电源电性连接的阴极20引线及阳极30引线，且阴极20和阳极30上均均匀分布有多个长方形网孔，阴极20和阳极30均采用钛材料制成。通过采用网状钛阴极20和网状钛阳极30，有利于阴阳离子在阴极 腔15和阳极腔16内快速的相对运动，实现提高EOW制备效率的效果。当然，在其他实施方案中，对阴极20和阳极30的形状不作具体限定，可根据实际需求进行选择，满足电解功能即可，并且阴极20和阳极30的材料也不限于为钛，另外网孔也可以为蜂窝状的六边形网孔等。
在某些实施方案中，无极性隔膜40为纳米陶瓷离子交换膜。使用纳米陶瓷离子交换膜，膜电阻低，电解效率高，进一步提高了EOW的制备效率，提升用户使用体验，并且，纳米陶瓷离子交换膜能耐强酸强碱性环境，避免在电解过程中被腐蚀，提高无极性隔膜40的使用寿命，节约生产成本。当然，在其他实施方案中，对无极性隔膜40的材料不作具体限定，为既可以通过阴离子又可以通过金属阳离子的无极性隔膜40即可，满足该低盐EOW电解槽100的电解需求。
在某些实施方案中，第一进液口131与第一出液口132交错设置，第二进液口141与第二出液口142交错设置。在某些实施方案中，第一进液口131与第一出液口132均开设在槽体10的外表面上，并均与阴极腔15连通，第一进液口131与第一出液口132设置在第三槽体13相对设置的两侧，且第一进液口131与第一出液口132的轴线方向不在同一直线上。同样地，第二进液口141与第二出液口142均开设在槽体10的外表面上，并均与阳极腔16连通，第二进液口141与第二出液口142设置在第四槽体14相对设置的两侧，且第二进液口141与第二出液口142的轴线方向不在同一直线上。如此，在制备EOW时，由第一进液口131和第二进液口141注入至阴极腔15和阳极腔16内的电解液，在阴极腔15或者阳极腔16内的路径加长，经过充分电解后，EOW可以由与第二进液口141错开的第二出液口142流出，碱性电位水可以由与第一进液口131错开的第一出液口132流出，从而使得整个电解反应过程充分进行，保证EOW的制备质量。当然，在其他实施方案中，也可以根据实际情况对各出液口及各进液口的情况进行相应调整。
在某些实施方案中，第一进液口131与第二进液口141开设在槽体10的同侧，第一出液口132与第二出液口142开设在槽体10的同侧。由于第一进液口131与第二进液口141开设在槽体10的同侧，便于分别从第一进液口131和第二进液口141注入电解液，并且，第一出液口132与第二出液口142开设在槽体10的同侧，便于分别对从第一出液口132和第二出液口142流出的EOW和碱性电位水进行收集与处理，整体结构设置上更加合理，制备过程更加容易，且在将该低盐EOW电解槽100安装后，也便于其他各结构的设置。
本公开另一实施例提供低盐EOW电解装置，如图5所示，低盐EOW电解装置除包括上述低盐EOW电解槽100外，还包括电源、控制器及交互器200，电源起到提供电能、实现整个装置供电的效果，控制器与电源电性连接，通过控制器智能控制整个EOW制备过程的自动化进行，交互器200为PLC触控屏，并与控制器电性连接，通过触控交互器200进行人机交互，进而控制整个低盐EOW电解装置或反馈整个低盐EOW电解装置工作信息。在某些实施方案中，为进一步提高EOW的制备效率，电解槽100可设置有两个。
在某些实施方案中，低盐EOW电解装置还包括机箱300，电解槽100、电源及控制器等均安装在机箱300内，使得整个低盐EOW电解装置外表看起来更加整洁、美观，并且机箱300上还开设有一开口，交互器200设置在该开口处，便于进行人机交互，整体布局上非常合理简单。另外，机箱300上还开设有与第一出液口132连通的第一排液口301及与第二出液口142连通的第二排液口302，以便将EOW和碱性电位水排出至机箱300外。
本公开又一实施例提供低盐EOW制备方法，低盐EOW制备方法用于上述低盐EOW电解装置，低盐EOW制备方法包括：电解液由第一进液口131和第二进液口141分别注入至阴极腔15和阳极腔16内；向阴极20和阳极30供电，阴极20和阳极30发生电解反应，且在阳极腔16内生成EOW，阴极腔15内生成碱性电 位水；以及生成的EOW由第二出液口142流出，生成的碱性电位水由第一出液口132流出。
该低盐EOW制备方法简单，便于EOW的制备，并且制备的EOW中含盐量较少，具有良好的杀菌效果。
需要说明的是，电解液为0.1％的氯化钠纯水盐溶液，制备EOW时，通过交互器200输入制备指令，电源接通，控制器控制电解液自动由第一进液口131和第二进液口141注入至阴极腔15和阳极腔16内，流量达到4L/min，并在一定电流密度下进行电解，在电场的作用下，阴极腔15内的氯离子在阳极30的吸引下通过无极性隔膜40迅速向阳极腔16移动，并在阳极30被还原成氯气，生产次氯酸，阳极腔16内的钠离子在阴极20的吸引下通过无极性隔膜40迅速向阴极腔15移动，阴极腔15内的钠离子残留量较少，从而在阳极腔16可产出低盐低PH的EOW，其中，EOW的PH值约为2-3，orp>1100mv，有效氯含量在50-70ppm，完全符合要求，而阴极腔15可产出碱性电位水，电解后的EOW由第二出液口142流出再经第二排液口302排出至机箱300外，可用于杀菌消毒，电解后的碱性电位水由第一出液口132流出再经第一排液口301排出至机箱300外。
以上所述仅为本公开的某些实施例，并不用以限制本公开，凡在本公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
