板式換熱器簡介：

板式換熱器是由(you)框架、傳熱板片組(zu)及夾緊螺栓(shuan)等主要(yao)部件組(zu)成。

框(kuang)架(jia)包括一個固(gu)定(ding)壓(ya)(ya)(ya)(ya)(ya)(ya)緊(jin)(jin)板(ban)(ban)(ban)和一個活(huo)動(dong)壓(ya)(ya)(ya)(ya)(ya)(ya)緊(jin)(jin)板(ban)(ban)(ban)，由上導(dao)(dao)桿與(yu)下導(dao)(dao)桿支承，在另‘端有一支柱。壓(ya)(ya)(ya)(ya)(ya)(ya)制成的(de)波紋板(ban)(ban)(ban)片(pian)懸掛在兩板(ban)(ban)(ban)之間(jian)的(de)上導(dao)(dao)桿上，移動(dong)活(huo)動(dong)壓(ya)(ya)(ya)(ya)(ya)(ya)緊(jin)(jin)板(ban)(ban)(ban)將板(ban)(ban)(ban)片(pian)組(zu)壓(ya)(ya)(ya)(ya)(ya)(ya)緊(jin)(jin)，再用一組(zu)夾(jia)(jia)緊(jin)(jin)螺柱將固(gu)定(ding)壓(ya)(ya)(ya)(ya)(ya)(ya)緊(jin)(jin)板(ban)(ban)(ban)和活(huo)動(dong)壓(ya)(ya)(ya)(ya)(ya)(ya)緊(jin)(jin)板(ban)(ban)(ban)夾(jia)(jia)緊(jin)(jin)至(zhi)一定(ding)尺(chi)寸(cun)。兩種介質經固(gu)定(ding)(或(huo)活(huo)動(dong))壓(ya)(ya)(ya)(ya)(ya)(ya)緊(jin)(jin)板(ban)(ban)(ban)上法蘭孔流入由波紋板(ban)(ban)(ban)片(pian)組(zu)成的(de)各自通道，熱(re)交換后介質再由固(gu)定(ding)(或(huo)活(huo)動(dong))壓(ya)(ya)(ya)(ya)(ya)(ya)緊(jin)(jin)板(ban)(ban)(ban)上的(de)法蘭孔流出。同定(ding)壓(ya)(ya)(ya)(ya)(ya)(ya)緊(jin)(jin)板(ban)(ban)(ban)、活(huo)動(dong)壓(ya)(ya)(ya)(ya)(ya)(ya)緊(jin)(jin)板(ban)(ban)(ban)、支柱及導(dao)(dao)桿均為低(di)碳(tan)鋼。考慮到用戶(hu)的(de)多種使用要(yao)求，框(kuang)架(jia)設計有多種型式(shi)，主要(yao)有雙支撐框(kuang)架(jia)式(shi)和常(chang)用的(de)落(luo)地式(shi)等，也(ye)可(ke)根據(ju)用戶(hu)的(de)要(yao)求更(geng)改框(kuang)架(jia)的(de)型式(shi)。

傳熱板(ban)(ban)(ban)片(pian)(pian)(pian)是板(ban)(ban)(ban)式(shi)換(huan)熱器的(de)(de)核心部件之一。波紋板(ban)(ban)(ban)片(pian)(pian)(pian)通(tong)過(guo)一次壓制成(cheng)型，合理(li)的(de)(de)波紋設計增加了(le)板(ban)(ban)(ban)片(pian)(pian)(pian)有(you)效傳熱面積，使(shi)流體(ti)順波紋通(tong)過(guo)時形成(cheng)湍流，強(qiang)化了(le)傳熱過(guo)程。裝配時波紋與波紋相交成(cheng)大(da)(da)量接(jie)觸抗點，大(da)(da)大(da)(da)提高了(le)板(ban)(ban)(ban)片(pian)(pian)(pian)組(zu)的(de)(de)剛度，因此能(neng)承受較高的(de)(de)壓力。每塊板(ban)(ban)(ban)片(pian)(pian)(pian)作為一個傳熱面，在(zai)密(mi)封墊(dian)的(de)(de)作用(yong)下(xia)，板(ban)(ban)(ban)片(pian)(pian)(pian)的(de)(de)兩側分(fen)別有(you)冷熱介質(zhi)通(tong)過(guo)，進行(xing)換(huan)熱。板(ban)(ban)(ban)片(pian)(pian)(pian)上有(you)四個分(fen)配液體(ti)的(de)(de)孑(jie)L，孑(jie)L及板(ban)(ban)(ban)片(pian)(pian)(pian)四周裝有(you)密(mi)封墊(dian)片(pian)(pian)(pian)，限制介質(zhi)在(zai)板(ban)(ban)(ban)片(pian)(pian)(pian)組(zu)內(nei)流動(dong)，各板(ban)(ban)(ban)片(pian)(pian)(pian)形成(cheng)平行(xing)的(de)(de)通(tong)道，流經(jing)里面的(de)(de)兩種介質(zhi)，作更佳(jia)換(huan)熱效果的(de)(de)方(fang)向流動(dong)，為適應多(duo)種腐(fu)(fu)蝕(shi)性(xing)較強(qiang)的(de)(de)介質(zhi)，波紋板(ban)(ban)(ban)片(pian)(pian)(pian)材(cai)料有(you)：工業(ye)純鈦TAl，用(yong)于海(hai)水(shui)或其它腐(fu)(fu)蝕(shi)性(xing)介質(zhi)；多(duo)種不銹鋼，用(yong)于淡水(shui)、飲用(yong)水(shui)、油(you)類及其它非腐(fu)(fu)蝕(shi)性(xing)介質(zhi)。

在波紋(wen)板片的(de)密(mi)(mi)封(feng)槽上裝有(you)密(mi)(mi)封(feng)墊(dian)片，密(mi)(mi)封(feng)墊(dian)片設(she)(she)計成(cheng)(cheng)雙(shuang)道(dao)密(mi)(mi)封(feng)結構，并(bing)且有(you)信號(hao)孔(kong)。當(dang)介質如從道(dao)密(mi)(mi)封(feng)泄(xie)露(lu)時，可從信號(hao)孑(jie)L泄(xie)出設(she)(she)備之外(wai)，便(bian)能(neng)及早發現問題加以解(jie)決，不(bu)會造成(cheng)(cheng)兩種介質的(de)混合(he)。密(mi)(mi)封(feng)墊(dian)片可根據不(bu)同(tong)的(de)流(liu)體和操(cao)作(zuo)溫度選用不(bu)同(tong)的(de)膠(jiao)種。

板(ban)式換(huan)熱器的技術優(you)勢和特點：

1、傳(chuan)熱(re)系(xi)數高：傳(chuan)熱(re)板(ban)片(pian)上(shang)的(de)特(te)殊波紋設計，可(ke)使流(liu)(liu)體在極低的(de)流(liu)(liu)速下產生(sheng)強烈的(de)湍流(liu)(liu)，湍流(liu)(liu)的(de)自凈效應又可(ke)防(fang)止(zhi)污垢的(de)產生(sheng)，使得板(ban)式換熱(re)器的(de)傳(chuan)熱(re)系(xi)數為(wei)管殼式換熱(re)器的(de)3-5倍。

2、經濟(ji)性：相同換熱量的(de)前(qian)提下，與管殼式比(bi)較：投資少、運行費用低、維修費用低。

3、可調整(zheng)性：只需(xu)增(zeng)加和減少板(ban)片(pian)即可滿足(zu)工(gong)藝過程改(gai)變的需(xu)求。

4、結構緊湊：在相同換熱量的前提下，占(zhan)用空間(jian)僅為管殼式的1／2一l／3。

5、易于潔洗維修。
