說起雙(shuang)管板換(huan)熱器很多(duo)人(ren)是(shi)見過的(de)(de)，但是(shi)卻不(bu)是(shi)經(jing)常使用。慢慢的(de)(de)隨著社(she)會經(jing)濟(ji)的(de)(de)發展，越來越多(duo)的(de)(de)設備(bei)方便化，而且(qie)人(ren)們(men)的(de)(de)見識也(ye)是(shi)越來越高(gao)，所以不(bu)知道雙(shuang)管板換(huan)熱器的(de)(de)，今天小(xiao)編就幫大家分析一下。
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)、雙管(guan)板(ban)換熱(re)器(qi)使(shi)用注意事(shi)項
1、當管程和殼程二介質相混合后(hou)會引(yin)起嚴重腐蝕(shi);
2、一側(ce)為極(ji)度或高(gao)度危害介質滲入到(dao)另一側(ce)會(hui)引起嚴重后果;
3、當管程和殼程介質(zhi)相(xiang)混(hun)合后(hou)兩(liang)種(zhong)介質(zhi)會引(yin)起燃燒或(huo)爆炸;
4、當(dang)一種介(jie)質混入另一種介(jie)質時(shi)，引起催化劑中毒;
5、管程和殼程介質相混合后會引(yin)起(qi)聚合或生成樹脂狀物質;
6、管程(cheng)和殼程(cheng)介質相(xiang)混合后會引起化學反應終止或限制;
7、管程和殼(ke)程介質(zhi)相混合后，引起產(chan)品(pin)污染或(huo)產(chan)品(pin)質(zhi)量下降。
二、雙管板換熱(re)器的(de)結構
