山東水升華EDI產品詳情簡介

EDI產品簡介 EDI Product Profile


EDI(Electrodeionization)是一種具有革命性意義的水處理技術,它巧妙地將電滲析與離子交換有機地結合在一起的膜分離脫鹽工藝,屬高科技綠色環保技術。EDI凈水設備具有連續出水、無需酸堿再生和無人值守等優點,已在制備純水的系統中逐步代替混床作為精處理設備使用。這種先進技術的環保特性好,操作使用簡便,愈來愈多地被人們所認可,也愈來愈多廣泛地在醫藥、電子、電力、化工等行業得到推廣。它的出現是水處理技術的一次革命性的進步,標志著水處理工業最終全面跨入綠色產業的行業。


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兩端分別設有正電極板和負電極板,通電后產生電場,電場使進水中的水分子在離子交換樹脂界面離解成H+及OH-,并不斷地再生淡水室中陰、陽離子交換樹脂。離子交換樹脂中的陰、陽離子在再生過程中受到相應正負電極的吸引,透過陽、陰離子交換樹脂向所對應的離子膜的方向遷移。當這些離子透過交換膜進入濃室后,H+和OH-重新結合成水。這種H+和OH-的產生、結合及陰、陽離子遷移正是離子交換樹脂得以實現連續再生的機理。這種H+和OH-的產生、結合及陰、陽離子遷移正是離子交換樹脂得以實現連續再生的機理。


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.
