在初級除氧階段，凝結水經過高壓噴嘴構成發散的錐形水膜向下進入初級除氧區，水膜在這個區域內與上行的過熱蒸汽充沛觸摸，迅速將水加熱到除氧器智能管殼式換熱器壓力下的飽和溫度，大部分氧氣從水中析出，在每個噴嘴的周圍設有四個排氣口，以及時排出析出的氧氣,經過初步除氧的水落入水空間流向出水口；加熱蒸汽經過排管從水下送入，與水混合加熱，同時對管殼式換熱器廠家水流進行(xing)擾動，并將水中的溶解(jie)氧(yang)及其它不凝(ning)結(jie)氣體從水中帶出水面，達到對凝(ning)結(jie)水進行(xing)深度除氧(yang)的意圖。

智能管殼式換熱器可按用途、換熱方式、結構和材料進行分類。a.按用途可分為：(1)加熱器。把管殼式換熱器廠家流(liu)體(ti)加(jia)熱(re)(re)(re)到必要的(de)溫(wen)度，但加(jia)熱(re)(re)(re)流(liu)體(ti)沒有發(fa)生相(xiang)的(de)變(bian)化。(2)預(yu)熱(re)(re)(re)器。預(yu)先加(jia)熱(re)(re)(re)流(liu)體(ti)，為(wei)后工(gong)序操(cao)作(zuo)提供標準的(de)工(gong)藝參數(shu)。(3)過熱(re)(re)(re)器。用(yong)于(yu)把流(liu)體(ti)(工(gong)藝氣或蒸汽)加(jia)熱(re)(re)(re)到過熱(re)(re)(re)狀態(tai)。(4)蒸發(fa)器。用(yong)于(yu)加(jia)熱(re)(re)(re)流(liu)體(ti)，達到沸點以上溫(wen)度，使其液體(ti)蒸發(fa)，一般有相(xiang)的(de)變(bian)化。(5)再(zai)沸器。用(yong)于(yu)使裝置中冷凝了的(de)液體(ti)再(zai)度加(jia)熱(re)(re)(re)，使其蒸發(fa)。 　

二、處理方法：（1）在無壓狀態，按制造廠提供的夾緊尺寸重新夾緊設備，尺寸應均勻一樣，壓緊尺寸的偏差應不大于±0.2N（mm）（N.為板片總數），兩壓緊板間的平行度應保持在2mm以內。（2）在管殼式換熱器廠家外漏部位上做好標記，然后換熱器解體逐一排查解決，重新裝配或更換墊片和板片。（3）將開智能管殼式換熱器解體，對板(ban)片(pian)變形部(bu)位進行修理(li)或者更換板(ban)片(pian)。在沒有(you)板(ban)片(pian)備件(jian)時可將變形部(bu)位板(ban)片(pian)暫時拆除后重新組裝使用(yong)。 　　

按照管殼式換熱器的(de)工藝用途來(lai)(lai)分的(de)話(hua)主要就是(shi)分為(wei)：板(ban)(ban)(ban)(ban)(ban)(ban)式(shi)(shi)加(jia)熱(re)(re)(re)器(qi)(qi)(qi)(qi)、板(ban)(ban)(ban)(ban)(ban)(ban)式(shi)(shi)冷(leng)卻(que)器(qi)(qi)(qi)(qi)、板(ban)(ban)(ban)(ban)(ban)(ban)式(shi)(shi)冷(leng)凝器(qi)(qi)(qi)(qi)、板(ban)(ban)(ban)(ban)(ban)(ban)式(shi)(shi)預熱(re)(re)(re)器(qi)(qi)(qi)(qi)。根據組合流(liu)程(cheng)來(lai)(lai)看(kan)是(shi)分為(wei)：單程(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)(re)(re)器(qi)(qi)(qi)(qi)和多程(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)(re)(re)器(qi)(qi)(qi)(qi)。當然了我們還可以(yi)根據兩種介質的(de)流(liu)動方向可以(yi)分為(wei)：順流(liu)板(ban)(ban)(ban)(ban)(ban)(ban)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)(re)(re)器(qi)(qi)(qi)(qi)、逆流(liu)板(ban)(ban)(ban)(ban)(ban)(ban)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)(re)(re)器(qi)(qi)(qi)(qi)、交叉流(liu)板(ban)(ban)(ban)(ban)(ban)(ban)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)(re)(re)器(qi)(qi)(qi)(qi)。如果按(an)照流(liu)道的(de)堿(jian)洗的(de)大小來(lai)(lai)分的(de)話(hua)就可以(yi)分為(wei)常規間(jian)隙板(ban)(ban)(ban)(ban)(ban)(ban)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)(re)(re)器(qi)(qi)(qi)(qi)和寬間(jian)隙板(ban)(ban)(ban)(ban)(ban)(ban)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)(re)(re)器(qi)(qi)(qi)(qi)了。
