說起雙管(guan)板(ban)(ban)換熱器很多人是見過(guo)的，但是卻不是經(jing)常使用。慢(man)慢(man)的隨著社會經(jing)濟的發展，越(yue)來越(yue)多的設備方便化，而且人們的見識也(ye)是越(yue)來越(yue)高，所以不知(zhi)道雙管(guan)板(ban)(ban)換熱器的，今天小編(bian)就幫大(da)家分(fen)析一下(xia)。
雙管板換熱器作為主要用于高溫、高壓、易燃、易爆、有毒或較強腐蝕介質的換熱器的工況下，若要更好地推廣應用，必須掌握好設計、制造、運行、維護各個環節，其中很重要就是雙管板換器制造質量要好，要求較高的制造精度，同時換熱管質量要好，保證在使用中不出現換熱管壁破裂的情況。
一(yi)、雙(shuang)管板換熱器(qi)使用(yong)注意事項
1、當管程和(he)殼程二介質相混合后會引起嚴重腐蝕;
2、一側為極度(du)或高度(du)危害介質(zhi)滲入(ru)到另一側會引起嚴重后果;
3、當管程和殼程介質相混合后兩(liang)種介質會引起燃(ran)燒或(huo)爆(bao)炸;
4、當(dang)一種(zhong)介質混入另一種(zhong)介質時，引起催(cui)化(hua)劑中毒;
5、管(guan)程和殼程介質相混合后會引(yin)起(qi)聚合或生(sheng)成(cheng)樹脂狀物質;
6、管程和殼程介質相混(hun)合后(hou)會引起化學反應終止或(huo)限(xian)制;
7、管程和(he)殼程介質相混合(he)后(hou)，引起(qi)產品污染或產品質量下(xia)降。
二、雙管板換熱器的結構
雙(shuang)(shuang)管(guan)(guan)板(ban)換(huan)(huan)熱(re)器(qi)采(cai)用(yong)(yong)固定管(guan)(guan)板(ban)結構，管(guan)(guan)束(shu)不能抽(chou)(chou)出(chu)清洗(xi)(xi)，這(zhe)是與單(dan)管(guan)(guan)板(ban)換(huan)(huan)熱(re)器(qi)可(ke)(ke)采(cai)用(yong)(yong)多種結構型(xing)式(shi)、管(guan)(guan)束(shu)可(ke)(ke)以(yi)抽(chou)(chou)出(chu)清洗(xi)(xi)不同的(de)地方(fang)。對(dui)于(yu)溫差較大的(de)雙(shuang)(shuang)管(guan)(guan)板(ban)換(huan)(huan)熱(re)器(qi)，筒(tong)體上可(ke)(ke)加(jia)裝波(bo)紋膨脹(zhang)節;而單(dan)管(guan)(guan)板(ban)換(huan)(huan)熱(re)器(qi)除可(ke)(ke)考慮筒(tong)體上加(jia)裝波(bo)紋膨脹(zhang)節外(wai)，常(chang)(chang)采(cai)用(yong)(yong)浮頭或(huo)U型(xing)管(guan)(guan)型(xing)式(shi)來補償(chang)。對(dui)于(yu)雙(shuang)(shuang)管(guan)(guan)板(ban)換(huan)(huan)熱(re)器(qi)，存在兩種設(she)計理念的(de)認(ren)識：一種認(ren)為雙(shuang)(shuang)管(guan)(guan)板(ban)換(huan)(huan)熱(re)器(qi)用(yong)(yong)于(yu)絕對(dui)防止管(guan)(guan)殼程(cheng)間介(jie)質混串的(de)場合，設(she)計在內外(wai)管(guan)(guan)板(ban)之間空腔(qiang)上加(jia)裝排(pai)液倒淋閥，供(gong)日常(chang)(chang)觀(guan)察和內管(guan)(guan)板(ban)發生(sheng)泄漏時排(pai)放，使得管(guan)(guan)殼程(cheng)介(jie)質切實被內外(wai)二層(ceng)管(guan)(guan)板(ban)隔離。這(zhe)是采(cai)用(yong)(yong)雙(shuang)(shuang)管(guan)(guan)板(ban)結構型(xing)式(shi)的(de)主要(yao)目的(de)。
另(ling)一種認(ren)為雙(shuang)(shuang)管(guan)(guan)(guan)(guan)板(ban)(ban)(ban)換熱(re)器(qi)可用于管(guan)(guan)(guan)(guan)殼(ke)程(cheng)(cheng)間(jian)(jian)(jian)介質壓(ya)(ya)差(cha)很(hen)大(da)的(de)(de)場(chang)合，設(she)計在內外(wai)管(guan)(guan)(guan)(guan)板(ban)(ban)(ban)之(zhi)間(jian)(jian)(jian)的(de)(de)空腔(qiang)(qiang)中加入一種介質，來減小(xiao)管(guan)(guan)(guan)(guan)殼(ke)程(cheng)(cheng)間(jian)(jian)(jian)介質的(de)(de)壓(ya)(ya)差(cha)。這和(he)一般單管(guan)(guan)(guan)(guan)板(ban)(ban)(ban)換熱(re)器(qi)一樣(yang)，不(bu)(bu)能(neng)絕對保證外(wai)管(guan)(guan)(guan)(guan)板(ban)(ban)(ban)上管(guan)(guan)(guan)(guan)口不(bu)(bu)發生泄漏(lou)。雙(shuang)(shuang)管(guan)(guan)(guan)(guan)板(ban)(ban)(ban)之(zhi)間(jian)(jian)(jian)的(de)(de)隔(ge)離(li)(li)腔(qiang)(qiang)是與單管(guan)(guan)(guan)(guan)板(ban)(ban)(ban)換熱(re)器(qi)結構主要(yao)(yao)區別之(zhi)處(chu)，該隔(ge)離(li)(li)腔(qiang)(qiang)不(bu)(bu)與管(guan)(guan)(guan)(guan)程(cheng)(cheng)、殼(ke)程(cheng)(cheng)相連(lian)通(tong)，不(bu)(bu)承受(shou)(shou)介質壓(ya)(ya)力(li)，但承受(shou)(shou)設(she)備的(de)(de)機械載荷與熱(re)載荷。隔(ge)離(li)(li)腔(qiang)(qiang)的(de)(de)承載能(neng)力(li)主要(yao)(yao)取決(jue)于雙(shuang)(shuang)管(guan)(guan)(guan)(guan)板(ban)(ban)(ban)間(jian)(jian)(jian)距。對固定(ding)式雙(shuang)(shuang)管(guan)(guan)(guan)(guan)板(ban)(ban)(ban)進行殼(ke)程(cheng)(cheng)水壓(ya)(ya)試驗時，內側管(guan)(guan)(guan)(guan)板(ban)(ban)(ban)與換熱(re)管(guan)(guan)(guan)(guan)連(lian)接處(chu)可能(neng)存在泄漏(lou)，故在確定(ding)雙(shuang)(shuang)管(guan)(guan)(guan)(guan)板(ban)(ban)(ban)間(jian)(jian)(jian)距時必須考慮觀察、檢漏(lou)所需要(yao)(yao)的(de)(de)最小(xiao)空間(jian)(jian)(jian)。
以上就是對雙(shuang)管板(ban)換熱器的(de)注意(yi)事項(xiang)和使用(yong)范圍的(de)介紹，不(bu)知大家看(kan)完有沒(mei)有學到(dao)很(hen)多東西(xi)呢，這對不(bu)知道(dao)和不(bu)了(le)解的(de)人來說(shuo)(shuo)，可以說(shuo)(shuo)是有著很(hen)大的(de)幫助呢。還有工作(zuo)人員，對于這些注意(yi)事項(xiang)也(ye)一定要知道(dao)。
