山东水升华EDI产品详情简介

EDI产品简介 EDI Product Profile


EDI(Electrodeionization)是一种具有革命性意义的水处理技术,它巧妙地将电渗析与离子交换有机地结合在一起的膜分离脱盐工艺,属高科技绿色环保技术。EDI净水设备具有连续出水、无需酸碱再生和无人值守等优点,已在制备纯水的系统中逐步代替混床作为精处理设备使用。这种先进技术的环保特性好,操作使用简便,愈来愈多地被人们所认可,也愈来愈多广泛地在医药、电子、电力、化工等行业得到推广。它的出现是水处理技术的一次革命性的进步,标志着水处理工业最终全面跨入绿色产业的行业。


EDI is a revolutionary water treatment technology. It cleverly combines electrodialysis and ion exchange organically with membrane separation and desalination technology. It is a high-tech green technology. EDI water purification equipment has the advantages of continuous water production, no acid-base regeneration, and no human presence. It has gradually replaced the mixed bed as a precision treatment equipment in the system for preparing pure water. The Environmental Protection characteristics of this advanced technology are good, the operation is easy to use, and it is more and more recognized by people. It is also more and more widely promoted in the pharmaceutical, electronics, electric power, and chemical industries. Its appearance is a revolutionary progress of water treatment technology, marking the water treatment industry finally entered the green industry industry.


EDI原理 EDIprinciple

 

EDI两端分别设有正电极板和负电极板,通电后产生电场,电场使进水中的水分子在离子交换树脂界面离解成H+及OH-,并不断地再生淡水室中阴、阳离子交换树脂。离子交换树脂中的阴、阳离子在再生过程中受到相应正负电极的吸引,透过阳、阴离子交换树脂向所对应的离子膜的方向迁移。当这些离子透过交换膜进入浓室后,H+和OH-重新结合成水。这种H+和OH-的产生、结合及阴、阳离子迁移正是离子交换树脂得以实现连续再生的机理。这种H+和OH-的产生、结合及阴、阳离子迁移正是离子交换树脂得以实现连续再生的机理。


Both ends of EDI are provided with positive electrode plates and negative electrode plates. After electrification, electric fields are generated. The electric field causes the water molecules entering the water to dissociate into H + and OH-at the interface of the ion exchange resin, and continuously regenerates the cathode and cation in the freshwater chamber. Exchange resin. The cathode and cation in the ion exchange resin are attracted by the corresponding positive and negative electrodes during the regeneration process, and migrate through the Yang and anion exchange resins to the corresponding Ionic membranes. When these ions enter the dense chamber through the exchange membrane, H+ and OH- recombine into water. The generation, binding, and cation migration of this H + and OH-are the mechanisms by which ion exchange resins can achieve continuous regeneration.
