EDI工作原理
首先是填充在模堆中的樹(shù)脂吸附原水中的離子而達(dá)到脫鹽的目的模堆兩端電極上的直流電使模堆內(nèi)部產(chǎn)生電位差,從而促使陽(yáng)離子向陰極移動(dòng),陰離子向陽(yáng)極移動(dòng),陰、陽(yáng)離子進(jìn)入濃縮室淡水室水電阻率升高到一定極限,水分子電離分散生成H+和OH-,以保持淡水室內(nèi)的樹(shù)脂經(jīng)常處于再生狀態(tài),實(shí)現(xiàn)連續(xù)脫鹽。
EDI的特點(diǎn)
1、脫鹽率高
2、水利用率高達(dá)95%
3、樹(shù)脂無(wú)需酸堿再生
4、運(yùn)行、操作、維護(hù)方便
5、視產(chǎn)水要求可將模塊不斷堆積,以適應(yīng)更大產(chǎn)水量的要求
6、流量范圍從1到450m3/h
7、運(yùn)行成本低,能耗少,每產(chǎn)水3.8m3/h,耗電IKW
