软化(hua)器，软水(shui)处(chu)理设(she)备，软化(hua)水(shui)设(she)备1-4吨每小时软水设备工作原理： 采用钠型强酸性阳离子树脂将原水中的钙、镁离子置换出去，经软化除盐设备处理后的水可直接 做为蒸汽锅炉的补给水。其化学反应为：2RNa+Ca2+(Mg2)=R2Ca(Mg)+2Na+。当树脂吸附到一定量的钙、镁离子后必须进行再生.1、加(jia)树(shu)(shu)(shu)(shu)脂(zhi)(zhi)用(yong)(yong)树(shu)(shu)(shu)(shu)脂(zhi)(zhi)离(li)子(zi)交(jiao)换(huan)的(de)(de)原理置换(huan)出(chu)原水(shui)(shui)中(zhong)(zhong)的(de)(de)钙镁(mei)离(li)子(zi)，因此能(neng)显(xian)著减少水(shui)(shui)中(zhong)(zhong)钙镁(mei)离(li)子(zi)含量，从根本(ben)上软化(hua)水(shui)(shui)质，但需要(yao)(yao)加(jia)盐(yan)来让树(shu)(shu)(shu)(shu)脂(zhi)(zhi)置换(huan)能(neng)力再生。一(yi)般(ban)在机器(qi)上有(you)(you)相应描(miao)述。2、加(jia)盐(yan)根据(ju)不同的(de)(de)机型(xing)(xing)加(jia)盐(yan)的(de)(de)时间都不一(yi)样，一(yi)般(ban)看盐(yan)箱快没盐(yan)了(le)就(jiu)可以加(jia)了(le)，一(yi)般(ban)加(jia)到(dao)盐(yan)箱容积(ji)的(de)(de)1/3--2/3处(chu)。3、设备专用(yong)(yong)盐(yan)碘(dian)对树(shu)(shu)(shu)(shu)脂(zhi)(zhi)颗(ke)粒的(de)(de)表(biao)(biao)面有(you)(you)很强(qiang)(qiang)的(de)(de)穿(chuan)透力，长期使(shi)(shi)用(yong)(yong)碘(dian)盐(yan)，使(shi)(shi)树(shu)(shu)(shu)(shu)脂(zhi)(zhi)的(de)(de)表(biao)(biao)面强(qiang)(qiang)度(du)(du)、硬(ying)度(du)(du)、机械强(qiang)(qiang)度(du)(du)、体积(ji)膨(peng)胀强(qiang)(qiang)度(du)(du)、圆(yuan)曲率降(jiang)低，树(shu)(shu)(shu)(shu)脂(zhi)(zhi)容易(yi)破(po)碎，树(shu)(shu)(shu)(shu)脂(zhi)(zhi)的(de)(de)交(jiao)换(huan)能(neng)力下降(jiang)（指强(qiang)(qiang)酸(suan)型(xing)(xing)树(shu)(shu)(shu)(shu)脂(zhi)(zhi)）软化(hua)水(shui)(shui)设备再一(yi)个(ge)强(qiang)(qiang)酸(suan)型(xing)(xing)阳离(li)子(zi)交(jiao)换(huan)树(shu)(shu)(shu)(shu)脂(zhi)(zhi)对反离(li)子(zi)的(de)(de)选择如下：Fe+3＞Al+3＞Ba+2＞Sr+2＞Ca+2＞Mg+2＞K+1＞NH4+1＞Na+1＞H+1＞Li+1。所以碘(dian)具有(you)(you)还原性质，会起到(dao)破(po)坏作(zuo)用(yong)(yong),偶尔(er)使(shi)(shi)用(yong)(yong)问(wen)题也(ye)不是很大4、参(can)考计(ji)算方(fang)法：一(yi)个(ge)软化(hua)床设计(ji)简(jian)易(yi)方(fang)法，希望能(neng)帮助需要(yao)(yao)的(de)(de)网(wang)友：首先要(yao)(yao)得到(dao)4组必要(yao)(yao)数据(ju)a. 原水(shui)(shui)中(zhong)(zhong)硬(ying)度(du)(du)浓(nong)(nong)度(du)(du)： XX mg/L(以碳(tan)酸(suan)钙计(ji))b. 每小时水(shui)(shui)流量：XX m3/hc. 树(shu)(shu)(shu)(shu)脂(zhi)(zhi)线流速：≤20m/hd. 树(shu)(shu)(shu)(shu)脂(zhi)(zhi)工作(zuo)交(jiao)换(huan)容量：900mol/m3然后将碳(tan)酸(suan)钙硬(ying)度(du)(du)浓(nong)(nong)度(du)(du)换(huan)算成离(li)子(zi)摩尔(er)浓(nong)(nong)度(du)(du)，如：原水(shui)(shui)中(zhong)(zhong)硬(ying)度(du)(du)浓(nong)(nong)度(du)(du)300 mg/L / CaCO3的(de)(de)分子(zi)量50（1/2） = 6 mmol/L然后就(jiu)能(neng)得出(chu)1立方(fang)树(shu)(shu)(shu)(shu)脂(zhi)(zhi)能(neng)处(chu)理多(duo)少吨(dun)原水(shui)(shui)，如：树(shu)(shu)(shu)(shu)脂(zhi)(zhi)工作(zuo)交(jiao)换(huan)容量900 ÷ 原水(shui)(shui)硬(ying)度(du)(du)离(li)子(zi)摩尔(er)浓(nong)(nong)度(du)(du)6 = 150 m3。
