混合離子交換器使用說明書

1、混合離子交換器Mixed of ion exchange使用說明書Operating Instruction一、工藝原理 Technical principle本公司生產(chǎn)的混合離子交換器(簡稱混床)，在脫鹽水工程中，用于二級(jí)脫鹽水的制備， 被處理的水由上向下流經(jīng)按一定的比例配比裝填并混合形成的強(qiáng)酸、 堿樹脂層來制取成品水。 均勻混合的樹脂層中，陽樹脂與陰樹脂緊密地交錯(cuò)排列，每一對(duì)陽樹脂與陰樹脂顆粒似于一 組復(fù)床，混床就象無數(shù)組串聯(lián)運(yùn)行的復(fù)床。通過混合離子交換后進(jìn)入水中的氫離子與氫氧離 子會(huì)立即生成電離度很低的水分子(H20)，很少可能形成陽離子或陰離子交換時(shí)的反離子， 使交換反應(yīng)進(jìn)行的十分徹底

2、，因而能制取純度相當(dāng)高的成品水。0ur company produces the mixed ion exchanger (referred to as ) of the mixed bed, in desalted water engineering, preparation for secondary desalting water, treated water by the down flow of mixed in certain proportion ratio of loading and the formation of acid, alkali, resin layer to

3、manufacture the finished water. Evenly mixed resin layer, with Yin Yang resin resin tightly staggered, each pair of Yang Yin resin particles and resin on a set of double bed, mixed bed, like countless group of double bed series operation. After ion exchange in the water by mixing hydrogen ion and hy

4、droxide ion will immediately generate low degree of ionization of water molecules (H20), less likely to form the cation or anion exchange of ions, make the exchange reaction of very thoroughly, thereby making high purity of the finished water.混床的再生工藝較陽、陰床的再生工藝復(fù)雜，混床樹脂層失效后，需先對(duì)床中樹脂進(jìn)行 反洗分層，使陽樹脂與陰樹脂徹底分離，
