Description
技术领域
本发明涉及清洗剂领域，具体是指一种反渗透膜清洗保护剂。
背景技术
反渗透膜能够有效脱盐，常作为水处理达标的把关工艺单元，已在海水淡化、纯水制备、锅炉给水、废水处理以及饮水、饮料和化工产品的浓缩等多种领域中得到了广泛的应用。反渗透装置在运行一段时间后，在反渗透膜浓水侧会积累胶体、金属氧化物、细菌、有机物或水垢等物质，导致反渗透膜污堵，从而引起系统脱盐率下降、产水量降低和压差增大等问题。及时有效的清洗反渗透膜表面的污堵物，对于缓解反渗透运行压力同时避免事态恶化，清洗剂的选择至关重要。一般而言，膜元件一旦过水工作后一段时间不用，停用期间要加保护剂，防止微生物生长破坏膜性能，现阶段虽然也有成品保护药剂，但价格很贵，后续机器重新启动时需特殊处理后才可正常使用，费时费力。
发明内容
本发明要解决的技术问题是克服上述技术的缺陷，提供一种反渗透膜清洗保护剂。
为解决上述技术问题，本发明提供的技术方案为一种反渗透膜清洗保护剂：包括以下质量份的原料：三聚磷酸钠3-36％、表面活性剂6-20％、磷酸氢二钠5-10％、以及余量的溶剂；
所述溶剂为去离子水。
本发明与现有技术相比的优点在于：本发明能够对反渗透膜进行清洗，清洗耗时少，清洗效果好，同时可以对反渗透膜进行保护，保护周期长，原料易得，造价较低，便于生产制造，后续机器重新启动时不需特殊处理，只需用清水冲洗即可，简单方便。
具体实施方式
实施例1，一种反渗透膜清洗保护剂，包括以下质量份的原料：三聚磷酸钠3％、表面活性剂6％、磷酸氢二钠5％、以及余量的溶剂，所述溶剂为去离子水。将三聚磷酸钠、表面活性剂、磷酸氢二钠加入去离子水中，搅拌充分混合即可。
实施例2，一种反渗透膜清洗保护剂，包括以下质量份的原料：三聚磷酸钠20％、表面活性剂13％、磷酸氢二钠8％、以及余量的溶剂，所述溶剂为去离子水。将三聚磷酸钠、表面活性剂、磷酸氢二钠加入去离子水中，搅拌充分混合即可。
实施例3，一种反渗透膜清洗保护剂，包括以下质量份的原料：三聚磷酸钠36％、表面活性剂20％、磷酸氢二钠10％、以及余量的溶剂，所述溶剂为去离子水。将三聚磷酸钠、表面活性剂、磷酸氢二钠加入去离子水中，搅拌充分混合即可。
以上对本发明及其实施方式进行了描述，这种描述没有限制性，如果本领域的普通技术人员受其启示，在不脱离本发明创造宗旨的情况下，不经创造性的设计出与该技术方案相似的实施方式及实施例，均应属于本发明的保护范围。
