EDI工作原理:
EDI裝置(zhi)將離子交換(huan)樹(shu)脂充夾(jia)在陰/陽離子交換(huan)膜之間形成EDI單元。EDI工作原(yuan)理如下圖所示(shi)。
EDI組件中將一定數量的(de)EDI單元(yuan)間(jian)用(yong)網狀物隔開，形成濃(nong)(nong)水(shui)(shui)(shui)(shui)室(shi)(shi)(shi)。又(you)在單元(yuan)組兩端(duan)設置(zhi)陰/陽(yang)電(dian)極。在直流電(dian)的(de)推動下(xia)，通(tong)過淡水(shui)(shui)(shui)(shui)室(shi)(shi)(shi)水(shui)(shui)(shui)(shui)流中的(de)陰陽(yang)離(li)(li)子分別(bie)穿過陰陽(yang)離(li)(li)子交換(huan)膜(mo)進入到濃(nong)(nong)水(shui)(shui)(shui)(shui)室(shi)(shi)(shi)而(er)在淡水(shui)(shui)(shui)(shui)室(shi)(shi)(shi)中去除。而(er)通(tong)過濃(nong)(nong)水(shui)(shui)(shui)(shui)室(shi)(shi)(shi)的(de)水(shui)(shui)(shui)(shui)將離(li)(li)子帶出系統(tong)(tong)，成為(wei)(wei)濃(nong)(nong)水(shui)(shui)(shui)(shui). EDI設備一般以反(fan)滲透（RO）純水(shui)(shui)(shui)(shui)作為(wei)(wei)EDI給水(shui)(shui)(shui)(shui)。RO純水(shui)(shui)(shui)(shui)電(dian)導率(lv)一般是40-2μS/cm（25℃）。EDI純水(shui)(shui)(shui)(shui)電(dian)阻(zu)率(lv)可以高達18 MΩ.cm(25℃)，但是根據(ju)去離(li)(li)子水(shui)(shui)(shui)(shui)用(yong)途和(he)系統(tong)(tong)配置(zhi)設置(zhi)，EDI純水(shui)(shui)(shui)(shui)適用(yong)于制(zhi)備電(dian)阻(zu)率(lv)要(yao)求在1-18.2MΩ.cm(25℃)的(de)純水(shui)(shui)(shui)(shui)。
