混合离子交换器 Mixed of ion exchange 使用说明书 Operating Instruction 一、工艺原理Technical principle 本公司生产的混合离子交换器（简称混床），在脱盐水工程中，用于二级脱盐水的制备，被处理的水由上向下流经按一定的比例配比装填并混合形成的强酸、碱树脂层来制取成品水。均匀混合的树脂层中，阳树脂与阴树脂紧密地交错排列，每一对阳树脂与阴树脂颗粒似于一组复床，混床就象无数组串联运行的复床。通过混合离子交换后进入水中的氢离子与氢氧离子会立即生成电离度很低的水分子（H2O），很少可能形成阳离子或阴离子交换时的反离子，使交换反应进行的十分彻底，因而能制取纯度相当高的成品水。 Our 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 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 hydroxide ion will immediately generate low degree of ionization of water molecules (H2O), 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. 混床的再生工艺较阳、阴床的再生工艺复杂，混床树脂层失效后，需先对床中树脂进行反洗分层，使阳树脂与阴树脂彻底分离，然后分别对阳、阴树脂进行再生、清洗、恢复交换能力并均匀混合，方可继续投入运行。 Mixed bed regeneration process is cation exchanger、anion exchanger regeneration process complex, mixed bed resin layer expires, should first to backwashing stratification of resin in the bed, make with cation resin and anion resin separation thoroughly, then respectively for cation resin、anion resin regeneration, cleaning, restore the exchange capacity and mixing, may continue to put into operation. 二、技术参数Technical parameters 进水Inlet water： 一级脱盐水或RO产水Level of desalted water or Reverse osmosis water 出水水质Effluent quality： 0.2μS/cm(25℃) SiO2泄漏20ug/l，PH接近中性 SiO2 leak 20 ug/l, the PH near neuter 工作压力Working pressure: 0.6MPa 工作温度Working temperature: 5-45℃ 运行流速Operating velocity: 40-60m/h 水反洗强度Water backwashing stre
