Description

一种碱性锅炉阻垢剂
技术领域
本发明涉及水处理技术领域，尤其涉及一种碱性锅炉阻垢剂。
背景技术
锅炉设备在长期使用后不可避免会出现结垢、锈蚀等现象，控制结垢是工业水处理的一大问题。阻垢剂是具有能分散水中的难溶性无机盐、阻止或干扰难溶性无机盐在金属表面的沉淀、结垢功能，并维持金属设备有良好的传热效果的一类药剂。冷换设备防腐阻垢剂以环氧树脂和特定氨基树脂为基料，加入适量的各种防锈、防腐等各种助剂配制而成，为单组分。它具有优异的屏蔽、抗渗、防锈性能、良好的阻垢、导热性，优良的耐弱酸、强碱、有机溶剂等性能，它的附着力强，且膜层光亮、柔韧、致密、坚硬。目前市场上的锅炉阻垢剂大多为酸性阻垢剂，虽然在一定程度上可以解决工业锅炉水处理的结构问题，但仍然存在很多缺点，酸性阻垢剂一般用于地下水、自来水、井水等；而对于原水为微生物较多的地表水、海水淡化、江河湖水等则不适合。
发明内容
针对上述问题，本发明的目的是提供一种适用于微生物较多的地表水、海水淡化、江河湖水的碱性锅炉阻垢剂，阻垢效果好，可延长锅炉的使用寿命，对环境友好。
本发明解决上述技术问题所采用的技术方案是：一种碱性锅炉阻垢剂，包括如下重量份的各组分：纯水：75-85％、强碱：3-10％、阻垢剂：5-15％、除氧剂：1-5％、金属缓蚀剂：0.2-1.0％。
优选地，所述强碱为氢氧化钠、氢氧化钾中的一种或它们的混合物。
优选地，所述阻垢剂为乙二胺四乙酸钠盐(EDTA-4Na)、氨基三叉二瞵酸(ATMP)、羟基乙叉二膦酸(HEDP)、乙二胺四亚甲基膦酸(EDTMPA)、多元醇磷酸酯(PAPE)、二亚乙基三胺五甲基膦酸(DTPMP)中的一种或多种。
优选地，所述除氧剂为碳酰肼、丙酮肟、联氨中的一种或多种。
优选地，所述金属缓蚀剂为苯骈三氮唑、甲基苯骈三氮唑中的一种或它们的混合物。
本发明的优点在于：
本发明的阻垢剂是由有机膦酸盐、有机缓蚀剂、除氧剂及分散剂等组成的复合物，具有优异的缓蚀阻垢性能，能够与炉内钙、镁盐类发生化学反应，使之变成水渣后排出炉外，并能在金属表面形成一层保护膜，使腐蚀速率大大降低。本品缓蚀阻垢主要成分为为有机系列，对设备安全，除垢彻底、腐蚀率低，且不含有毒有害物质，经简单的中和处理后就可以排放，安全环保。
