第一,真空、電化學、化學除氧器概述
在鍋(guo)(guo)(guo)爐(lu)給水(shui)(shui)(shui)處理工藝過程(cheng)中(zhong),除氧(yang)(yang)(yang)是一個非常關鍵的(de)環節。氧(yang)(yang)(yang)是給水(shui)(shui)(shui)系統(tong)和(he)鍋(guo)(guo)(guo)爐(lu)的(de)主(zhu)要腐(fu)蝕性物(wu)(wu)質,給水(shui)(shui)(shui)中(zhong)的(de)氧(yang)(yang)(yang)應當迅速得到清(qing)除,否則它會(hui)(hui)腐(fu)蝕鍋(guo)(guo)(guo)爐(lu)的(de)給水(shui)(shui)(shui)系統(tong)和(he)部件,腐(fu)蝕物(wu)(wu)氧(yang)(yang)(yang)化(hua)鐵會(hui)(hui)進入鍋(guo)(guo)(guo)爐(lu)內,沉積或附(fu)在鍋(guo)(guo)(guo)爐(lu)管(guan)(guan)壁和(he)受熱面上,形成(cheng)(cheng)難溶而傳熱不良的(de)鐵垢,而且腐(fu)蝕會(hui)(hui)造成(cheng)(cheng)管(guan)(guan)道內壁出現點(dian)坑,阻(zu)力(li)系數增大(da)。管(guan)(guan)道腐(fu)蝕嚴(yan)重時,甚至(zhi)會(hui)(hui)發(fa)生管(guan)(guan)道爆炸事故。國家規(gui)定蒸(zheng)發(fa)量大(da)于(yu)(yu)等于(yu)(yu)2T/H的(de)蒸(zheng)汽鍋(guo)(guo)(guo)爐(lu),水(shui)(shui)(shui)溫(wen)大(da)于(yu)(yu)等于(yu)(yu)95℃的(de)熱水(shui)(shui)(shui)鍋(guo)(guo)(guo)爐(lu)都必需除氧(yang)(yang)(yang)。多年來眾多鍋(guo)(guo)(guo)爐(lu)給水(shui)(shui)(shui)處理工作者(zhe)一直(zhi)都在探(tan)索(suo)既高效又經濟的(de)除氧(yang)(yang)(yang)方法,兩級真空、電(dian)化(hua)學(xue)(xue)、化(hua)學(xue)(xue)三種除氧(yang)(yang)(yang)方法為一體的(de)除氧(yang)(yang)(yang)器。適用(yong)常溫(wen)水(shui)(shui)(shui)除氧(yang)(yang)(yang),具有其它除氧(yang)(yang)(yang)方法無法比(bi)擬的(de)優越性,適用(yong)性廣泛。
第(di)二,真空、電化學、化學除(chu)氧器原理
第(di)一步:兩級(ji)真空除(chu)氧(yang)
真空(kong)(kong)除(chu)氧器采用全密閉結構,運行(xing)期(qi)間(jian)自始至終(zhong)處(chu)于真空(kong)(kong)狀態。給水(shui)(shui)首先(xian)通過(guo)電解(jie)(jie)池進入強旋膜(mo)裝(zhuang)置,兩級真空(kong)(kong)除(chu)氧的(de)(de)工作(zuo)原理是應用亨利定(ding)律和道爾頓(dun)定(ding)律,根據亨利定(ding)律可知 ,在(zai)(zai)封閉容器中,任何氣體同(tong)時存在(zai)(zai)于水(shui)(shui)面(mian)上(shang) ,則氣體的(de)(de)溶(rong)解(jie)(jie)度(du)與其(qi)自己的(de)(de)分(fen)壓(ya)(ya)力(li)(li)(li)成正比(bi) ,而(er)且氣體的(de)(de)溶(rong)解(jie)(jie)度(du)僅與其(qi)本身的(de)(de)分(fen)壓(ya)(ya)力(li)(li)(li)有關。在(zai)(zai)一定(ding)壓(ya)(ya)力(li)(li)(li)下 ,隨著水(shui)(shui)溫(wen)升高(gao) ,水(shui)(shui)蒸汽(qi)的(de)(de)分(fen)壓(ya)(ya)力(li)(li)(li)增大(da) ,而(er)空(kong)(kong)氣和氧氣的(de)(de)分(fen)壓(ya)(ya)力(li)(li)(li)越(yue)來越(yue)小(xiao)。在(zai)(zai) 100℃時 ,氧氣的(de)(de)分(fen)壓(ya)(ya)力(li)(li)(li)降低到零(ling) ,水(shui)(shui)中的(de)(de)溶(rong)解(jie)(jie)氧也(ye)降低到零(ling)。當(dang)水(shui)(shui)面(mian)上(shang)壓(ya)(ya)力(li)(li)(li)小(xiao)于大(da)氣壓(ya)(ya)力(li)(li)(li)時 ,氧氣的(de)(de)溶(rong)解(jie)(jie)度(du)在(zai)(zai)較低水(shui)(shui)溫(wen)時也(ye)可達(da)到零(ling)。這樣(yang),水(shui)(shui)面(mian)上(shang)空(kong)(kong)間(jian)氧氣分(fen)子被析出 ,或轉變成其(qi)它氣體 ,從而(er)氧的(de)(de)分(fen)壓(ya)(ya)力(li)(li)(li)為零(ling) ,水(shui)(shui)中氧氣就(jiu)不(bu)斷地逸出,在(zai)(zai)負壓(ya)(ya)作(zuo)用下被除(chu)去90%的(de)(de)溶(rong)解(jie)(jie)氧。兩級真空(kong)(kong)除(chu)氧為滿足(zu)真空(kong)(kong)降低沸點(dian),達(da)到較好(hao)的(de)(de)效果(guo)。
