板式換熱器簡介：

板式(shi)換熱器是由框(kuang)架、傳熱板片組(zu)及夾緊螺(luo)栓等主要部件組(zu)成。

框架(jia)包括一(yi)個固(gu)定(ding)壓(ya)(ya)(ya)緊(jin)(jin)(jin)板(ban)(ban)(ban)(ban)(ban)和一(yi)個活(huo)(huo)(huo)動(dong)壓(ya)(ya)(ya)緊(jin)(jin)(jin)板(ban)(ban)(ban)(ban)(ban)，由(you)上(shang)(shang)(shang)導桿與下導桿支(zhi)承，在另‘端有一(yi)支(zhi)柱。壓(ya)(ya)(ya)制成(cheng)(cheng)的(de)波紋板(ban)(ban)(ban)(ban)(ban)片(pian)(pian)(pian)懸掛在兩(liang)板(ban)(ban)(ban)(ban)(ban)之間的(de)上(shang)(shang)(shang)導桿上(shang)(shang)(shang)，移(yi)動(dong)活(huo)(huo)(huo)動(dong)壓(ya)(ya)(ya)緊(jin)(jin)(jin)板(ban)(ban)(ban)(ban)(ban)將板(ban)(ban)(ban)(ban)(ban)片(pian)(pian)(pian)組(zu)壓(ya)(ya)(ya)緊(jin)(jin)(jin)，再用一(yi)組(zu)夾緊(jin)(jin)(jin)螺柱將固(gu)定(ding)壓(ya)(ya)(ya)緊(jin)(jin)(jin)板(ban)(ban)(ban)(ban)(ban)和活(huo)(huo)(huo)動(dong)壓(ya)(ya)(ya)緊(jin)(jin)(jin)板(ban)(ban)(ban)(ban)(ban)夾緊(jin)(jin)(jin)至一(yi)定(ding)尺寸。兩(liang)種(zhong)介質(zhi)經固(gu)定(ding)(或活(huo)(huo)(huo)動(dong))壓(ya)(ya)(ya)緊(jin)(jin)(jin)板(ban)(ban)(ban)(ban)(ban)上(shang)(shang)(shang)法(fa)蘭(lan)孔流入(ru)由(you)波紋板(ban)(ban)(ban)(ban)(ban)片(pian)(pian)(pian)組(zu)成(cheng)(cheng)的(de)各自(zi)通道(dao)，熱(re)交(jiao)換后介質(zhi)再由(you)固(gu)定(ding)(或活(huo)(huo)(huo)動(dong))壓(ya)(ya)(ya)緊(jin)(jin)(jin)板(ban)(ban)(ban)(ban)(ban)上(shang)(shang)(shang)的(de)法(fa)蘭(lan)孔流出(chu)。同定(ding)壓(ya)(ya)(ya)緊(jin)(jin)(jin)板(ban)(ban)(ban)(ban)(ban)、活(huo)(huo)(huo)動(dong)壓(ya)(ya)(ya)緊(jin)(jin)(jin)板(ban)(ban)(ban)(ban)(ban)、支(zhi)柱及導桿均(jun)為(wei)低碳鋼(gang)。考慮到(dao)用戶的(de)多(duo)(duo)種(zhong)使用要(yao)求(qiu)，框架(jia)設計有多(duo)(duo)種(zhong)型式，主要(yao)有雙支(zhi)撐(cheng)框架(jia)式和常用的(de)落地(di)式等，也可根據用戶的(de)要(yao)求(qiu)更改框架(jia)的(de)型式。

傳(chuan)熱(re)(re)(re)板(ban)(ban)(ban)片(pian)(pian)(pian)(pian)是板(ban)(ban)(ban)式換熱(re)(re)(re)器的(de)核心部件之一(yi)(yi)。波(bo)紋(wen)板(ban)(ban)(ban)片(pian)(pian)(pian)(pian)通(tong)過(guo)一(yi)(yi)次(ci)壓(ya)制(zhi)成(cheng)型，合(he)理的(de)波(bo)紋(wen)設計增加了(le)板(ban)(ban)(ban)片(pian)(pian)(pian)(pian)有(you)效(xiao)傳(chuan)熱(re)(re)(re)面(mian)積，使流(liu)體順波(bo)紋(wen)通(tong)過(guo)時形成(cheng)湍流(liu)，強化了(le)傳(chuan)熱(re)(re)(re)過(guo)程。裝配時波(bo)紋(wen)與波(bo)紋(wen)相交(jiao)成(cheng)大量接觸抗點，大大提高了(le)板(ban)(ban)(ban)片(pian)(pian)(pian)(pian)組(zu)的(de)剛度，因(yin)此(ci)能承受(shou)較(jiao)(jiao)高的(de)壓(ya)力。每塊板(ban)(ban)(ban)片(pian)(pian)(pian)(pian)作為(wei)(wei)一(yi)(yi)個傳(chuan)熱(re)(re)(re)面(mian)，在(zai)密(mi)封墊的(de)作用(yong)下，板(ban)(ban)(ban)片(pian)(pian)(pian)(pian)的(de)兩(liang)側分別有(you)冷熱(re)(re)(re)介(jie)質(zhi)(zhi)(zhi)通(tong)過(guo)，進行(xing)換熱(re)(re)(re)。板(ban)(ban)(ban)片(pian)(pian)(pian)(pian)上有(you)四(si)個分配液體的(de)孑L，孑L及板(ban)(ban)(ban)片(pian)(pian)(pian)(pian)四(si)周裝有(you)密(mi)封墊片(pian)(pian)(pian)(pian)，限制(zhi)介(jie)質(zhi)(zhi)(zhi)在(zai)板(ban)(ban)(ban)片(pian)(pian)(pian)(pian)組(zu)內流(liu)動，各板(ban)(ban)(ban)片(pian)(pian)(pian)(pian)形成(cheng)平行(xing)的(de)通(tong)道，流(liu)經里(li)面(mian)的(de)兩(liang)種介(jie)質(zhi)(zhi)(zhi)，作更佳換熱(re)(re)(re)效(xiao)果的(de)方向流(liu)動，為(wei)(wei)適應(ying)多(duo)種腐(fu)蝕(shi)性(xing)較(jiao)(jiao)強的(de)介(jie)質(zhi)(zhi)(zhi)，波(bo)紋(wen)板(ban)(ban)(ban)片(pian)(pian)(pian)(pian)材料有(you)：工業(ye)純鈦TAl，用(yong)于海水(shui)或其它(ta)腐(fu)蝕(shi)性(xing)介(jie)質(zhi)(zhi)(zhi)；多(duo)種不銹鋼，用(yong)于淡水(shui)、飲(yin)用(yong)水(shui)、油(you)類(lei)及其它(ta)非腐(fu)蝕(shi)性(xing)介(jie)質(zhi)(zhi)(zhi)。

在波紋板(ban)片的密(mi)(mi)封槽上裝(zhuang)有密(mi)(mi)封墊(dian)片，密(mi)(mi)封墊(dian)片設(she)(she)計成(cheng)雙道密(mi)(mi)封結構(gou)，并且有信號孔(kong)。當介(jie)質如從(cong)(cong)道密(mi)(mi)封泄露(lu)時，可(ke)(ke)從(cong)(cong)信號孑L泄出設(she)(she)備(bei)之外，便(bian)能(neng)及早發現(xian)問題(ti)加以解決，不會造成(cheng)兩(liang)種介(jie)質的混合。密(mi)(mi)封墊(dian)片可(ke)(ke)根據(ju)不同的流體和操作溫度選用不同的膠種。

板式換熱器的技術(shu)優勢和特(te)點(dian)：

1、傳熱(re)系數高：傳熱(re)板片上的(de)(de)(de)特殊波紋設計，可使流(liu)體(ti)在極低(di)的(de)(de)(de)流(liu)速下產生強烈的(de)(de)(de)湍流(liu)，湍流(liu)的(de)(de)(de)自(zi)凈效(xiao)應(ying)又(you)可防止污垢的(de)(de)(de)產生，使得板式(shi)換熱(re)器(qi)的(de)(de)(de)傳熱(re)系數為管殼式(shi)換熱(re)器(qi)的(de)(de)(de)3-5倍。

2、經濟性：相同換熱量的前(qian)提下，與管殼(ke)式比較(jiao)：投資少、運行費(fei)用低、維修費(fei)用低。

3、可調整性：只需增(zeng)加和(he)減少板片即可滿足(zu)工藝過(guo)程改(gai)變的(de)需求(qiu)。

4、結構緊湊：在相(xiang)同換熱量(liang)的(de)前提下，占用空間(jian)僅為管(guan)殼式的(de)1／2一l／3。

5、易(yi)于潔洗(xi)維修。
