Description

一种自来水除氯剂 技术领域
本发明涉及水处理技术领域，具体涉及一种自来水除氯剂。
背景技术
自来水厂通常采用液氯或漂白粉对自来水进行灭菌消毒处理，造成自来水中含有一定量的游离氯。根据国家饮用水标准，自来水用户末端管道游离氯的含量不得低于0.05mg/升，然而该“余氯”能与水中的有机物质作用，产生对人体有害的含氯有机物，如氯仿、二氯乙烯、四氯化碳等。因此有必要对自来水进行除氯操作，以消除“余氯”带来的危害。
常用的自来水除氯材料包括活性炭、凯得菲(KDF)多金属滤料、硫基化合物等。
活性炭通过吸附作用，吸附过滤水中的有机化学物质和氯。但当水温较高时(例如沐浴用水)，吸附能力就会迅速失效。而且，受吸附容量的限制，活性炭过滤滤芯的有效使用寿命也十分短，且可能因污物的积累堵塞而失效。
凯得菲(KDF)多金属滤料为高纯度铜锌合金，也是一种广泛使用的除氯剂。其通过逆转氯与钠离子在溶液中的分离的电子化学过程，除去游离氯。但受作用机理的限制，该滤料不能去除氯胺。而且它也受水温影响，在冷水条件下除氯效果很差。此外，含KDF的滤芯会影响水压，当水压不够大时，水会绕过KDF而无法起作用。KDF最大的问题是使用寿命取决于水质。当水质较差时，KDF过滤出来的污物会覆盖在KDF表面，导致KDF迅速失效。
硫基化合物，如亚硫酸钙和亚硫酸钠(或硫酸基盐)作为除氯剂，通常用于处理工业用水。因这些硫基化合物对人体有毒，它们在日常生活用水中的使用仍有争议。
维生素C自身的酸性特性使其可被用作无毒安全的除氯剂。其目前可 在医药领域用于苛刻条件的水质除氯。但因存在计量困难的缺陷，导致难以在家庭使用中普及。
发明内容
本发明旨在解决现有技术的以上问题，提供一种安全无毒，且适于家庭普及使用的自来水除氯剂。
本发明采用以下技术方案：一种自来水除氯剂，其为固体并且包括：维生素C成分，10-35％(重量)；载体成分，10-65％(重量)；食用防腐剂，0.1-0.5％(重量)。
一些实施例中，所述维生素C成分可以包括：维生素C、维生素C的钠盐、维生素C的钙盐、异维生素C、异维生素C的钠盐、异维生素C的钙盐，或它们的任意组合。
一些实施例中，所述载体成分可以为淀粉、糊精、聚乙二醇，或它们的任意组合。
一些实施例中，所述自来水除氯剂还可以包括可溶性添加剂。
一些实施例中，所述可溶性添加剂可以为：香料、色素，或它们的任意组合。
一些实施例中，香料的用量可以为5-12％(重量)。
一些实施例中，色素的用量可以为0.001-0.1％(重量)。
一些实施例中，所述自来水除氯剂可以由以下组成：
Figure PCTCN2014092923-appb-000001
本发明利用维生素C成分的除氯净水功能，将其与适当配比的载体成分、防腐剂一起制成固体，从而可以在使用中逐渐溶出，解决了计量困难，难以在家庭应用中普及的问题。该除氯剂安全、无毒、使用方便，且不受水温影响，也不存在基于吸附的除氯材料吸附容量受限的缺陷。
具体实施方式
下面结合具体实施例对本发明作进一步详细说明。
本发明将适当配比的载体成分、食用防腐剂，与维生素C成分一起制成固体，其中各组分的配比为：维生素C成分10-35％(重量)；载体成分10-65％(重量)；食用防腐剂0.1-0.5％(重量)。其可以随着水流动，而逐渐溶解，并逐步释放适量的维生素C到自来水中，用于除氯。
该除氯剂的全部成分均安全无毒。例如，载体可以为淀粉、糊精、聚乙二醇或他们的混合，并且淀粉可以是大米、玉米、木薯、土豆等的淀粉；糊精可以是上述淀粉的糊精、麦芽糊精等；食用防腐剂可以为山梨酸钾、苯甲酸钠等。通过巧妙配比，使得维生素C成分的释放量既能起到除氯的效果，又不会导致维生素C过量。解决了现有技术中计量困难的缺陷，方便家庭的普及使用。
本发明的除氯剂还可以包括可溶性添加剂，例如香料、食用色素，等等，或是它们的任意组合。它们各自的重量配比分别可以为5-12％、0.001-0.1％。其中香料可以是日化香料、食用香料、植物提取精油等；色素可以是食用色素、化妆品色素或颜料。
本发明的除氯剂制作简便，例如可以通过先将其他成分混合之后，再加入维生素C成分混合均匀，最后利用挤出设备，挤出填充入容器固化即可。其在使用上也同样方便，只需将其置于自来水出口前端即可。
下表1提供根据本发明具体实施例得到的除氯剂的配方。
表1：

Figure PCTCN2014092923-appb-000003
除氯试验：
将本发明的除氯剂填充于盖上开有约0.3mm小孔的管状容器，并置于花洒管中，于三口之家使用。试验时间30天，分别于第1天、第15天、第30天取经过花洒的水于第三方检测机构(TUV)根据GB/T 5750.11-2006检测游离氯含量。结论示于下表2中。
表2：

结合以上表1和表2的结果可见，本发明的自来水除氯剂能够有效去除自来水中的余氯。在30天的实验周期内，除氯效果较为稳定、持续；有效解决了现有技术中使用维生素C除氯计量困难的缺陷，方便在家庭中普 及使用。
以上所述本发明的具体实施方式，并不构成对本发明保护范围的限定。任何根据本发明的技术构思所作出的各种其他相应的改变与变形，均应包含在本发明权利要求的保护范围内。
