山西世同水處(chu)理為您分享(xiang)：EDI超純水設備(bei)具有如下優點： 

1、出(chu)水(shui)水(shui)質(zhi)具有佳(jia)的穩定度。

 2、能連(lian)續生(sheng)產出符合(he)用戶要求的超純水(shui)。

 3、模塊(kuai)化生產(chan)，并(bing)可實現PLC全自動(dong)控制。

 4、不需酸堿再生，無污水排放(fang)。降(jiang)低了勞動強(qiang)度，節省了酸堿和(he)大量清潔水，減(jian)少(shao)了環境污染。

 5、不會因再(zai)生而(er)停機。

 6、單一系(xi)統(tong)連續(xu)運轉，不需備用(yong)(yong)(yong)系(xi)統(tong)。 超純水(shui)流(liu)程(cheng) 近幾年EDI去(qu)離(li)子(zi)(zi)(zi)在各(ge)(ge)個(ge)工(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)領域(yu)都越來越受重(zhong)視，許多(duo)(duo)(duo)工(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)系(xi)統(tong)開(kai)始采用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)去(qu)離(li)子(zi)(zi)(zi)作為(wei)其水(shui)處(chu)(chu)(chu)(chu)理(li)系(xi)統(tong)的更新換代技術，如(ru)電(dian)(dian)(dian)(dian)(dian)(dian)力工(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)、制藥(yao)工(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)、微電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)工(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)、電(dian)(dian)(dian)(dian)(dian)(dian)鍍(du)與(yu)金屬(shu)表面(mian)處(chu)(chu)(chu)(chu)理(li)等。 (1)電(dian)(dian)(dian)(dian)(dian)(dian)力工(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye) 據(ju)推算電(dian)(dian)(dian)(dian)(dian)(dian)力行(xing)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)水(shui)處(chu)(chu)(chu)(chu)理(li)單元的操作費用(yong)(yong)(yong)約(yue)占電(dian)(dian)(dian)(dian)(dian)(dian)力成(cheng)本(ben)的10%，而用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)去(qu)離(li)子(zi)(zi)(zi)替代離(li)子(zi)(zi)(zi)交換樹脂可(ke)以(yi)使每(mei)處(chu)(chu)(chu)(chu)理(li)1000加侖水(shui)的成(cheng)本(ben)由11美(mei)元降(jiang)至1.75美(mei)元。 (2)制藥(yao)工(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye) 雖(sui)然藥(yao)用(yong)(yong)(yong)水(shui)的特(te)點是(shi)并不要(yao)求很高(gao)的去(qu)離(li)子(zi)(zi)(zi)程(cheng)度(du)，但(dan)電(dian)(dian)(dian)(dian)(dian)(dian)去(qu)離(li)子(zi)(zi)(zi)系(xi)統(tong)具有(you)同時(shi)去(qu)鹽和控(kong)制微生(sheng)物指標的特(te)點，因(yin)此(ci)已(yi)有(you)多(duo)(duo)(duo)家企業(ye)(ye)(ye)(ye)(ye)(ye)(ye)采用(yong)(yong)(yong)RO/EDI集成(cheng)系(xi)統(tong)。據(ju)稱該(gai)類系(xi)統(tong)性能穩定，全流(liu)程(cheng)計算機連續(xu)監控(kong)，全自(zi)動操作無(wu)人值守(shou)。 (3)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)工(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye) 電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)工(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)對水(shui)質的要(yao)求高(gao)，水(shui)電(dian)(dian)(dian)(dian)(dian)(dian)阻率要(yao)穩定的大(da)于18MΩ,而EDI出水(shui)一般(ban)在15-17 MΩ左右(you)，因(yin)此(ci)在電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)級水(shui)的生(sheng)產過(guo)程(cheng)多(duo)(duo)(duo)采用(yong)(yong)(yong)EDI+拋(pao)光樹脂系(xi)統(tong)，即在EDI之(zhi)(zhi)后加離(li)子(zi)(zi)(zi)交換，此(ci)工(gong)(gong)程(cheng)雖(sui)然仍需離(li)子(zi)(zi)(zi)交換，但(dan)由于EDI已(yi)除去(qu)了大(da)部(bu)分離(li)子(zi)(zi)(zi)，拋(pao)光樹脂幾乎不用(yong)(yong)(yong)再(zai)生(sheng)，因(yin)此(ci)水(shui)處(chu)(chu)(chu)(chu)理(li)費用(yong)(yong)(yong)仍然很低。 (4)電(dian)(dian)(dian)(dian)(dian)(dian)鍍(du)與(yu)金屬(shu)表面(mian)處(chu)(chu)(chu)(chu)理(li) 電(dian)(dian)(dian)(dian)(dian)(dian)去(qu)離(li)子(zi)(zi)(zi)可(ke)用(yong)(yong)(yong)于電(dian)(dian)(dian)(dian)(dian)(dian)鍍(du)廢水(shui)處(chu)(chu)(chu)(chu)理(li)可(ke)以(yi)使水(shui)重(zhong)復使用(yong)(yong)(yong)并回收重(zhong)金屬(shu)離(li)子(zi)(zi)(zi)。美(mei)國已(yi)有(you)該(gai)類型(xing)系(xi)統(tong)的實驗裝置。 (5)其他(ta)領域(yu) DI去(qu)離(li)子(zi)(zi)(zi)水(shui)設(she)(she)備在食品(pin)工(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)、化(hua)(hua)(hua)學工(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)等都有(you)很廣泛的應用(yong)(yong)(yong)：多(duo)(duo)(duo)室(shi)流(liu)化(hua)(hua)(hua)床(chuang)、設(she)(she)備的橫截面(mian)一般(ban)為(wei)矩形，用(yong)(yong)(yong)垂直擋(dang)(dang)板將設(she)(she)備沿(yan)長度(du)方向分成(cheng)多(duo)(duo)(duo)室(shi)(一般(ban)4～8室(shi))。擋(dang)(dang)板下沿(yan)與(yu)分布(bu)板面(mian)之(zhi)(zhi)間(jian)留有(you)幾十毫米的間(jian)隙，作為(wei)室(shi)間(jian)粉粒通(tong)道。后一室(shi)有(you)控(kong)制床(chuang)面(mian)的堰(yan)板。流(liu)體平(ping)行(xing)進入各(ge)(ge)室(shi)，顆(ke)粒則依次通(tong)過(guo)各(ge)(ge)室(shi)，因(yin)此(ci)多(duo)(duo)(duo)室(shi)流(liu)化(hua)(hua)(hua)床(chuang)不僅能抑制顆(ke)粒在整個(ge)床(chuang)層(ceng)內的返混，而且還能調節通(tong)入各(ge)(ge)室(shi)流(liu)體的流(liu)速和溫度(du)。多(duo)(duo)(duo)室(shi)流(liu)化(hua)(hua)(hua)床(chuang)比(bi)多(duo)(duo)(duo)層(ceng)流(liu)化(hua)(hua)(hua)床(chuang)設(she)(she)備容易控(kong)制，總壓降(jiang)也小(xiao);但(dan)傳熱、傳質推動力較(jiao)多(duo)(duo)(duo)層(ceng)床(chuang)小(xiao)，用(yong)(yong)(yong)于干(gan)燥(zao)時(shi)空氣熱量利(li)用(yong)(yong)(yong)效率較(jiao)差。 兩器流(liu)化(hua)(hua)(hua)床(chuang) 有(you)兩個(ge)流(liu)化(hua)(hua)(hua)床(chuang)，在左側流(liu)化(hua)(hua)(hua)。
