在电解槽中使液体产生电解离子或电解基团的方法及装置 技术领域
本发明涉及产生电解离子或电解基团的电解方法及装置,更具体地说,涉及一种采 用适当电流密度并配合离子或基团注入介质如活化炭来增强电解离子或电解基团产生 的电解方法及装置。 发明背景
众所周知, 在隔膜电解槽中电解水, 阴、 阳电极两侧分别产生氢气和氧气。 由于电引力的结果, 溶液发生离子电泳现象。 其结果, 阳极侧生成酸性物质, 溶 液变成酸性溶液, 阴极侧的溶液则变成碱性溶液。
电解水溶液时产生的碱性电解水能够抑制异常的肠道发酵等, 也可供饮用。 另一方面, 酸性电解水被认为具有杀菌作用和收敛作用等等, 可用于清洁和医疗 领域。 因此, 无论是酸性电解水还是碱性电解水都可适用于保健方面, 在医疗、 电子工业和食品工业有广泛用途。
电解水的参数通常采用代表氢离子浓度的 pH值和氧化还原电位。
对于碱性电解水, 当氧化还原电位相对较低时, 多数情况下对健康能够产生 良好效果。 当氧化还原电位相对较高时, 多数情况下对健康的作用不大。 一般来 说, 当氧化还原电位在 -50至 -250mV的范围内, 碱性电解水对保健的效果较佳。 当氧化还原电位在 +100至 +250mV的范围内, 碱性电解水的保健效果较差。
对于酸性电解水, 当氧化还原电位相对较高时, 多数情况下具有较好的收敛 和杀菌作用。 当氧化还原电位和溶解的氧浓度相对较低时, 多数情况下其收敛和 杀菌作用较差。 一般来说, 当 pH值小于 4, 氧化还原电位大于 +800mV时, 酸性 电解水对皮肤有明显的收敛作用, 即使在水蒸发后, 皮肤仍然保持光滑, 并且收 敛作用持续时间长。 当 pH值小于 3.5, 氧化还原电位大于 +900mV时, 酸性电解 水具有很强的杀菌活性, 能够在很短时间杀死大部分细菌, 而又不会损害皮肤或 黏膜, 因此是有用的有效抗菌剂。
自来水等原水的质量随着季节、 水温、 地区等而变化。 水质会显著影响由电 解装置产生的电解水的氧化还原电位。 所以, 也会改变由此产生的碱性电解水和 酸性电解水的 pH值和氧化还原电位, 这样就无法保证所希望得到的效果。 另外, 相关的电解方法和装置仍然产生含有微量添加剂的各种稀水溶液, 极大地限制了
其电解水溶液的应用范围。
考虑到前述的情形, 希望能提供一种高效地使电解液产生电解离子或电解基 团, 以获得稳定的并具有所希望的电解度的酸性和碱性电解溶液的方法和装置。 发明内容

将待电解的液体加入到所述电解槽内; 以及
在所述阴极电极和阳极电极之间施加直流电流或脉冲电流, 使所述电解槽内 的液体电解, 以产生电解离子或基团。
较佳地, 所述的电解槽还包括用于分隔所述阴极室和所述阳极室的隔膜。 本发明优选的离子或基团注入介质是活化炭 (active carbon;), 其中活化炭是一 种经过特殊加工的炭粒, 其形式也可以为粉状, 根据电解液体的不同或实际需要选 用不同的粒度。
本发明的方法适用于电解如下液体: 酸性水溶液、 碱性水溶液或油, 其中水溶 液包括自来水、海水、井水、工业废水等等, 油包括重油和轻油。根据本发明的方法, 水溶液经过电解步骤之后, 所述阳极室流出的电解水溶液的 pH值在 1.4至 7.0之 间, 所述阴极室流出的电解水溶液的 pH值在 7.0至 12.5之间。
根据需要,本发明施加在阴极电极与阳极电极之间的电流的电流密度在 50A/m2 至 800A/m2范围之间, 优选在 200 A/m2至 800 A/m2范围之间。 所述电解的液体具有 +500mV以上和 -400mV以下的氧化还原电位。
根据本发明的方法, 所述电解步骤可以连续操作或者间歇操作, 采用连续、 脉冲 或圆形波形供电。
通过本发明方法电解之后的液体可用于以下至少一种用途: 石油化学工业、 杀菌、 保健饮品、 食品洗涤、 医疗处理、 化妆品、 喷雾、 除臭、 防锈、 植物生长、 消毒、 宠物 /动物护理、 池喷水、 贮水、 水族箱水、 和净化。
本发明另一方面涉及一种使液体产生电解离子或电解基团的装置, 所述装置 包括:

在本发明的电解装置中, 所述的电解槽可制成圆柱体或正方体, 所述的阴极电 极和阳极电极可以是圆形或平的网状电极或板状电极。

以下将结合附图对本发明的构思、具体结构及产生的技术效果作进一步说明, 以充分地了解本发明的目的、 特征和效果。 但这些附图只起举例说明作用, 不能 理解为对本发明的限制。 附图说明
图 1所示为本发明的一实施例的使液体产生电解离子或电解基团的装置的概 略剖视图。 具体实施方式
参照图 1所示,本发明的一种使液体产生电解离子或电解基团的装置 10包括 一电解槽 100, 用于储存待电解的液体 400, 例如各类水和油。 所述电解槽 100 包括一个阴极室 200和一个阳极室 300。 所述阴极室 200和阳极室 300由一隔膜 600分隔开。所述电解槽 100内大部分空间装满了离子或基团注入介质 500, 起着 注入离子或基团的作用。
电解槽 100可根据不同的要求制成各种不同的形状, 如圆柱体、 长方体或立
方体等。 电解槽 100的材料可以是钢材、 水泥或陶瓷等, 当用于腐蚀性强的电解 液时, 可在电解槽内加上耐腐蚀性的树脂或橡胶衬里。
电解槽 100内的液体 400可以是各类水溶液或油,其中水溶液包括但不限于: 自来水、 海水、 井水、 工业废水等等, 油包括但不限于: 燃油、 重油和轻油等等。
在所述阴极室 200配置一个阴极电极 210, 在所述阳极室配室一个阳极电极
310。 它们尽可能互相接近地垂直安装在各自的电解室内, 以减少电极间之间距, 从而减底电压损失, 这是本领域技术人员所公知的。 阴极电极 210和阳极电极 310 由导电性良好的材料制成。 阴极电极和阳极电极可选自由钛、 铂、 钯、 铁、 钴、 镍、 铜、 锌及其合金组成的组中的一种金属或其合金制成, 优选用钛或钛合金制成。 所述的阳极电极和阴极电极也可以用导电性非金属制成, 例如石墨。 当然, 所述 阳、 阴电极所采用的材料并不仅限于上述的这些材料。 阴极电极 210 和阳极电极 310可以做成圆形或平的网状电极或板状电极。 为了降低阳、 阴电极的自腐蚀速度及 提高其利用率, 所述的电极可涂有保护层。所述的保护层主要由金属氧化物构成, 例如对于电解液体是海水的情形, 所述金属氧化物可选用 RuO2-TiO2-IrO2-SnO2 或 IrO2-TaO5。
隔膜 600由可容许电离子或基团通过的导电良好的材料制成, 如阳离子交换膜、 阴离子交换膜、 或其它可使离子有选择地通过的膜, 如聚丙烯、 聚乙烯等聚合物 薄膜。
在阴极电极 210和阳极电极 310之间施加直流电流或脉冲电流进行电解, 可 采用连续、 脉冲或圆形波形供电。 根据不同电解液的种类、 所希望得到的电解溶液的 pH值等不同实际需要,施加阴、阳电极之间的电流密度在 50A/m2至 800A/m2范围之间, 优选在 200 A/m2至 800A/m2之间。
在本实施例中, 离子或基团介质 500是活化炭。 活化炭可以是活化炭粉或活 化炭粒, 视乎实际需要而定。 电解槽 100可以完全装满或部分装满活化炭, 只要 电解液 400在电解槽 100内可以充分地自由流动即可。 活化炭在本发明中作为催 化介质催化电解过程中液体分子的电化学反应, 因此可以在电解过程中使电解液 增加产生离子或基团。 具体地, 当在阴极电极 210和阳极电极 310之间施加直流 电流或脉冲电流时, 电解离子或基团被转移到活化炭表面上, 并与阴极室 200和 阳极室 300内或者隔膜 600上的离子或分子进行反应,例如 H+能够与电解液分子有 效地反应, 籍此在电解过程中催化电解反应, 从而增强电解离子或基团的产生。 如本领域技术人员所知, 活化炭的粒度越细, 其表面积越大, 越有利于电解反应
的催化, 得到的效果也越好。
根据本发明的方法, 阳极室 300发生阳极反应, 阴极室 200发生阴极反应。 例如, 若电解液是水, 则阳极反应得到氧气和氢离子, 流出的酸性电解水溶液的 pH值在 1.4至 7.0之间; 阴极反应得到氢气和氢氧根离子, 流出的碱性电解水溶 液的 pH值在 7.0至 12.5之间。 得到的酸性和碱性电解水溶液不含有任何其它电荷相 反的化合物离子, 因此具有保健作用, 并且不会破坏环境。
用本发明的方法电解得到的液体具有 +500mV 以上和 -400mV 以下的氧化还原电 位。
通过本发明方法电解之后的电解溶液具有上述的 pH值和氧化还原电位, 因 此可以用于以下的用途: 石油化学工业、 杀菌、 保健饮品、 食品洗涤、 医疗处理、 化妆品、 喷雾、 除臭、 防锈、 植物生长、 消毒、 宠物 /动物护理、 池喷水、 贮水、 水族箱水、 和净化。 实施例
使用如图 1所示的电解装置 10, 电解槽内装了占其容积约 3/4的活化炭, 电 解的液体为自来水。 电解的条件如下:
直流电流: 1.38A, 25v;
温度: 室温
电解时间: 10分钟
阴极材料: 不锈钢网状电极
阳极材料: 钛金属合金
隔膜: 聚合物离子交换膜
结果显示, 电解 10分钟之后, 阳极侧电解水溶液的 pH值从 7.2下降到 2.7, 氧化还原电位是 +230mV, 而阴极侧电解水溶液的 pH值从 7.2上升到 10.9, 氧化 还原电位是 -223mV。 与之相比, 采用常规电解方法进行电解, 即使电解 1小时之 后, 电解槽内水溶液的 pH值仍然没有发生明显的改变。 由此可见, 本发明的电 解方法不仅可以大大缩短电解时间, 而且可以明显地增强电解液产生电解离子或 基团的能力。
虽然上述对本发明的较佳实施例进行了详细地描述, 但是, 对于本领域技术 人员来说, 只要不脱离本发明的设计思想及构思是可以作出各样不同的变改或者 改型。 应当说, 这样一些变型或改型都属于本发明的保护范围。
