一方面，本公开提供制备不含金属离子的EOW的电解槽10，如图1至图3所示，制备不含金属离子的EOW的电解槽10包括槽体11、阴离子膜组件12、阴极13以及阳极14，槽体11内形成有腔体，且槽体11上还开设有用于注入电解液的注液口111、用于进入纯水的进水口112及用于流出EOW的出水口113，阴离子膜组件12位于腔体内，并将腔体分隔形成阴极腔114和阳极腔115，注液口111与阴极腔114连通，进水口112及出水口113均与阳极腔115连通，阴极13位于阴极腔114内，阳极14位于阳极腔115内。
在某些实施方案中，制备不含金属离子的EOW的装置的电解槽10，包括槽体11、阴离子膜组件12、阴极13以及阳极14，阴 离子膜组件12将槽体11内的腔体分隔形成阴极腔114和阳极腔115，且槽体11上开设有与阴极腔114连通的注液口111及与阳极腔115连通的进水口112，在制备EOW时，可将电解液注入至阴极腔114内，纯水注入至阳极腔115内，阴极腔114内的阴极13和阳极腔115内的阳极14发生电解反应，且在阳极腔115内生成EOW，然后阳极腔115内的EOW可由出水口113流出，实现EOW的制备。由于阴离子膜组件12只容许带负电荷的离子通过而限制带正电荷的离子通过，故阴极腔114内的阴离子可以通过阴离子膜组件12，并在阳极腔115内生成EOW，而阴极腔114内的金属阳离子无法通过阴离子膜组件12进入阳极腔115内，从而阳极腔115内生成的EOW中不会含有金属阳离子，保证制备的EOW良好的杀菌效果。
在某些实施方案中，阴离子膜组件12呈环形设置在腔体内。在某些实施方案中，槽体11是由顶板、底板及四个侧板围合形成的一长方体形状且内部中空的结构，阴离子膜组件12包括顺次连接的四个阴离子膜组，四个阴离子膜组分别平行于四个侧板，并分别与四个侧板之间留有间隙，其中，阴离子膜组包括离子膜支架及阴离子膜，离子膜支架由两个结构相同的长方体形状的支架装配连接形成，离子膜固定于其间，且离子膜支架上分布有多个使离子膜露出的窗口，还包括固定支架，固定支架垂直于阴离子膜组设置，且四个阴离子膜组通过固定支架固定在顶板上，另外，为形成一个相对封闭的腔体，槽体11还包括围设在四个侧板外并与底板抵接的围板。该制备不含金属离子的EOW的电解槽10，阴离子膜组件12与四个侧板之间的空间为阳极腔115，其余的空间为阴极腔114，由于电解液需要注入至阴极腔114内，阴极腔114的容积远大于阳极腔115的容积，整体结构设置合理，并且在电解时，一方面阴极腔114内的阴离子可以通过阴离子膜组件12均匀分散进入至阳极腔115内，并生成EOW由出水口113流出，另一方面便于多个阴离子顺利通过，提高EOW的制备效率。在某些实施方案中，顶板和底板上均开设有卡槽，四个侧板均卡固在 顶板和底板的卡槽内，固定支架上也开设有卡槽，四个离子膜支架均卡固在固定支架的卡槽内。当然，在其他实施方案中，对阴离子膜组件12的形状不作具体限定。
在某些实施方案中，阴极13呈环形设置在阴极腔114内，阳极14呈环形设置在阳极腔115内。在某些实施方案中，阴极13呈顶部与底部开口的长方体形状，阳极14与阴极13形状类似，且槽体11的底板上分别开设有供阴极13和阳极14的引线穿过的电极孔，并在电极孔处进行密封处理，而且，为便于离子在腔体内自由的移动，阴极13和阳极14可采用网状结构。采用上述结构的阴极13和阳极14，阴极13和阳极14面积相对较大，可以提高电解时的灵敏度，以分别在阴极腔114和阳极腔115内充分进行不同的化学反应，并且离子的移动速度较快，进一步提高EOW的制备效率和制备质量。当然，在其他实施方案中，阴极13和阳极14的形状不限于此，并且也可不采用网状电极，阴极13与槽体11的顶板和底板之间可留有一定间隙，即阴极13浸泡在电解液内，以便离子通过，阳极14与槽体11的顶板和底板之间也可留有一定间隙。
在某些实施方案中，进水口112与出水口113分别开设在槽体11上相对的两侧，注液口111的轴线方向垂直于进水口112和出水口113的轴线方向。在某些实施方案中，进水口112与出水口113分别开设在槽体11的两个相对设置的侧板上，且进水口112与出水口113的轴线方向不在同一直线上，注液口111开设在顶板上。如此，使得该制备不含金属离子的EOW的电解槽10整体结构设置上更加合理，便于进水口112、出水口113及注液口111的开设，而且，纯水由一侧板上的进水口112进入至阳极腔115内，在阳极腔115内的路径加长，电解反应的距离更远，可在经过充分电解后再由另一相对侧板上的出水口113流出，电解反应效果更好。当然，在其他实施方案中，注液口111、进水口112及出水口113的开设位置可根据实际需要。
在某些实施方案中，制备不含金属离子的EOW的电解槽10 还包括用于排出阴极腔114内废液的溢流管15。如此，电解后的阴极腔114内的废液可经溢流管15迅速排出，以便收集或集中清理，其中，废液为碱性电位水，可作清洁液。
另一方面，本公开提供制备不含金属离子的EOW的装置，如图4至图7所示，制备不含金属离子的EOW的装置包括电解槽10。
在某些实施方案中，制备不含金属离子的EOW的装置还包括循环箱20，进水口112通过进水管31连通循环箱20，出水口113通过出水管32连通循环箱20，且循环箱20上还开设有用于注入纯水的注水口21及用于排出EOW的排水口，排水口处设置有排水管22。制备EOW时，将纯水由注水口21注入至循环箱20内，电解由注液口111注入至阴极腔114内，循环箱20内的纯水可以经进水管31不断由进水口112进入至阳极腔115内进行电解，且电解后的EOW可以经出水管32不断由出水口113流回至循环箱20内，从而实现在循环箱20与电解槽10之间不断的循环电解，既可以保证EOW的制备质量，又可以保证EOW的制备效率，直至EOW制备完成，EOW可经排水管22由排水口排出，以用于杀菌消毒。在某些实施方案中，考虑到纯水在循环箱20与电解槽10之间顺利循环，还包括循环水泵23，循环水泵23设置在出水管32或进水管31上，并且考虑到EOW顺利排出，还包括排水泵，排水泵设置在排水管22上，以及考虑到阴极腔114内废液的顺利排出，还包括排液泵，排液泵设置在溢流管15上，循环水泵23、排水泵及排液泵分别起到提供输送能量的效果。在某些实施方案中，为进一步提高EOW的制备效率，电解槽10可设置有两个。
在某些实施方案中，制备不含金属离子的EOW的装置还包括PH检测件40，PH检测件40用于检测循环箱20内液体的PH值。在纯水通过循环水泵23在电解槽10的阳极腔115与循环箱20之间不断循环电解的过程中，PH检测件40实时对循环箱20内液体的PH值进行检测，当PH检测件40检测到循环箱20内液体的PH值在2至3之间时，说明EOW制备完成，电解槽10停止工作， 此时可将EOW由循环箱20内排出。通过设置PH检测件40，可以对循环箱20内液体的PH值进行实时检测，并反馈PH数据，且在PH检测合格后再排出EOW，实现通过PH控制EOW的制备，保证制备的EOW符合酸性要求，其中，PH检测件40可以为PH计等。
在某些实施方案中，制备不含金属离子的EOW的装置还包括液位传感器，液位传感器用于检测循环箱20内液体的液位。在某些实施方案中，液位传感器为接触式液位传感器，液位传感器包括高液位感应件51及低液位感应件52，当循环箱20内液体的液位达到最高液位要求时，高液位感应件51被触发，当循环箱20内液体的液位达到最低液位要求时，低液位感应件52被触发。制备EOW时，初始时，循环箱20内液体的液位低于最高液位，打开注水口21处的电磁阀开关，循环箱20内的纯水由注水口21注入至循环箱20内，直至触发高液位感应件51，电磁阀开关关闭停止注水，电解槽10开始工作，电解由注液口111注入至阴极腔114内，纯水不断由循环箱20进入电解槽10的阳极腔115内循环电解，当循环箱20内液体的PH值在2-3之间时，电解槽10停止工作，EOW经排水管22由排水口排出，直至触发低液位感应件52，重新回到初始进入反复制水的过程。通过设置高液位感应件51和低液位感应件52，可以分别进行最高液位和最低液位的检测，实现通过PH和液位传感器控制EOW的制备，保证整个循环制水过程的顺利进行。
在某些实施方案中，制备不含金属离子的EOW的装置还包括电源60及控制器70，电源60起到提供电能、实现整个装置供电的效果，控制器70与电源60、PH检测件40、高液位感应件51及低液位感应件52等各结构均电性连接，液位传感器或者PH检测件40可实时反馈液位数据或者PH数据到控制器70，然后通过控制器70进行自动化控制，实现对整个EOW制备过程的智能控制的效果，保证该制备不含金属离子的EOW的装置的各结构正常运转。在某些实施方案中，制备不含金属离子的EOW的装置还包 括交互器80，交互器80与控制器70电性连接，通过交互器80进行人机交互，实现控制整个装置或反馈整个装置工作信息的效果，其中，交互器80可以为PLC触控屏等具有交互功能的器件。
在某些实施方案中，制备不含金属离子的EOW的装置还包括机箱90，电解槽10、循环箱20、电源60、控制器70及交互器80等均安装在机箱90上，电解槽10、循环箱20、电源60及控制器70均位于机箱90内，使得整个装置外表看起来更加整洁、美观，而交互器80位于机箱90外，便于进行人机交互，机箱90分为上下两层，电解槽10和循环箱20位于下层且并列设置，电源60和控制器70位于上层，整体布局上非常合理简单。另外，在某些实施方案中，机箱90底端的四个角上还分别设有向下伸出的支脚，以起到对整个装置的支撑作用。
另一方面，本公开还涉及制备不含金属离子的EOW的方法，该方法用于上述制备不含金属离子的EOW的装置，包括：电解液由注液口111注入至阴极腔114内，纯水由进水口112进入至阳极腔115内；向阴极13和阳极14供电，阴极13和阳极14发生电解反应，且在阳极腔115内生成EOW；以及生成的EOW由出水口113流出。
该制备不含金属离子的EOW的方法简单，便于EOW的制备，并且制备的EOW中不含有金属阳离子，具有良好的杀菌效果。
需要说明的是，电解液为纯水盐溶液，制备EOW时，通过交互器80输入制备指令，电源60接通，控制器70控制注水口21处的电磁阀开关打开，纯水由注水口21注入至循环箱20内，直至触发高液位感应件51，高液位感应件51反馈数据到控制器70，电磁阀开关关闭停止注水，此时控制器70控制电解槽10开始工作，电解液由注液口111注入至阴极腔114内，循环箱20内的纯水经进水管31不断由进水口112进入至阳极腔115内，并在一定电流密度下进行电解，阴离子膜组件12只允许氯离子通过而阻止钠离子通过，阳极14主要发生析氯反应、析氧反应，进而在阳极腔115得到不含钠离子的EOW，其主要成分为氯气、次氯酸、次 氯酸根、盐酸、溶解氧和臭氧等，且电解后的EOW经出水管32不断由出水口113流回至循环箱20内，如此循环电解，PH检测件40在此过程中实时对循环箱20内液体的PH值进行检测，当PH检测件40检测到循环箱20内液体PH值在2-3之间时，PH检测件40反馈数据到控制器70，此时控制器70控制电解槽10停止工作，制备完成的EOW经排水管22由排水口排出至储存筒，直至触发低液位感应件52，低液位感应件52反馈数据到控制器70，EOW排放完成，该EOW可用于杀菌消毒，阴极腔114内废液经溢流管15迅速排出，回到初始重复上述操作进入反复制水的过程，整个制水过程自动化进行。
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。
