板式換熱(re)器簡介：

板式換熱器是(shi)由(you)框架、傳熱板片組(zu)及夾緊(jin)螺栓等主要(yao)部件組(zu)成。

框架(jia)包括一(yi)(yi)(yi)個固定(ding)壓(ya)(ya)緊(jin)(jin)板(ban)(ban)和(he)一(yi)(yi)(yi)個活動(dong)(dong)壓(ya)(ya)緊(jin)(jin)板(ban)(ban)，由上(shang)(shang)導桿(gan)與下導桿(gan)支(zhi)承，在另‘端有(you)一(yi)(yi)(yi)支(zhi)柱(zhu)。壓(ya)(ya)制成(cheng)的(de)(de)波紋(wen)板(ban)(ban)片(pian)懸掛在兩(liang)板(ban)(ban)之間的(de)(de)上(shang)(shang)導桿(gan)上(shang)(shang)，移動(dong)(dong)活動(dong)(dong)壓(ya)(ya)緊(jin)(jin)板(ban)(ban)將(jiang)板(ban)(ban)片(pian)組(zu)壓(ya)(ya)緊(jin)(jin)，再用(yong)一(yi)(yi)(yi)組(zu)夾(jia)緊(jin)(jin)螺柱(zhu)將(jiang)固定(ding)壓(ya)(ya)緊(jin)(jin)板(ban)(ban)和(he)活動(dong)(dong)壓(ya)(ya)緊(jin)(jin)板(ban)(ban)夾(jia)緊(jin)(jin)至一(yi)(yi)(yi)定(ding)尺寸。兩(liang)種介(jie)質經固定(ding)(或活動(dong)(dong))壓(ya)(ya)緊(jin)(jin)板(ban)(ban)上(shang)(shang)法蘭孔流入由波紋(wen)板(ban)(ban)片(pian)組(zu)成(cheng)的(de)(de)各(ge)自通道(dao)，熱交換后介(jie)質再由固定(ding)(或活動(dong)(dong))壓(ya)(ya)緊(jin)(jin)板(ban)(ban)上(shang)(shang)的(de)(de)法蘭孔流出。同定(ding)壓(ya)(ya)緊(jin)(jin)板(ban)(ban)、活動(dong)(dong)壓(ya)(ya)緊(jin)(jin)板(ban)(ban)、支(zhi)柱(zhu)及導桿(gan)均(jun)為低碳(tan)鋼。考慮到用(yong)戶的(de)(de)多種使用(yong)要(yao)求，框架(jia)設計有(you)多種型式(shi)(shi)，主(zhu)要(yao)有(you)雙支(zhi)撐框架(jia)式(shi)(shi)和(he)常用(yong)的(de)(de)落地式(shi)(shi)等，也可根據用(yong)戶的(de)(de)要(yao)求更改框架(jia)的(de)(de)型式(shi)(shi)。

傳(chuan)熱(re)板(ban)(ban)(ban)片(pian)(pian)(pian)是板(ban)(ban)(ban)式換熱(re)器的(de)(de)(de)核心(xin)部件之一(yi)。波紋(wen)(wen)板(ban)(ban)(ban)片(pian)(pian)(pian)通過(guo)一(yi)次壓制(zhi)(zhi)成(cheng)型，合理的(de)(de)(de)波紋(wen)(wen)設計增加了(le)板(ban)(ban)(ban)片(pian)(pian)(pian)有(you)效傳(chuan)熱(re)面積，使流(liu)體順波紋(wen)(wen)通過(guo)時(shi)形成(cheng)湍流(liu)，強化了(le)傳(chuan)熱(re)過(guo)程(cheng)。裝(zhuang)(zhuang)配時(shi)波紋(wen)(wen)與(yu)波紋(wen)(wen)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)(de)剛度，因此能承(cheng)受(shou)較高的(de)(de)(de)壓力。每塊板(ban)(ban)(ban)片(pian)(pian)(pian)作為一(yi)個(ge)傳(chuan)熱(re)面，在密封墊的(de)(de)(de)作用(yong)下(xia)，板(ban)(ban)(ban)片(pian)(pian)(pian)的(de)(de)(de)兩側分別有(you)冷熱(re)介(jie)質(zhi)(zhi)(zhi)通過(guo)，進行換熱(re)。板(ban)(ban)(ban)片(pian)(pian)(pian)上有(you)四個(ge)分配液體的(de)(de)(de)孑(jie)L，孑(jie)L及(ji)板(ban)(ban)(ban)片(pian)(pian)(pian)四周裝(zhuang)(zhuang)有(you)密封墊片(pian)(pian)(pian)，限制(zhi)(zhi)介(jie)質(zhi)(zhi)(zhi)在板(ban)(ban)(ban)片(pian)(pian)(pian)組(zu)內流(liu)動(dong)，各板(ban)(ban)(ban)片(pian)(pian)(pian)形成(cheng)平(ping)行的(de)(de)(de)通道，流(liu)經里面的(de)(de)(de)兩種介(jie)質(zhi)(zhi)(zhi)，作更佳換熱(re)效果(guo)的(de)(de)(de)方(fang)向(xiang)流(liu)動(dong)，為適(shi)應(ying)多種腐蝕性較強的(de)(de)(de)介(jie)質(zhi)(zhi)(zhi)，波紋(wen)(wen)板(ban)(ban)(ban)片(pian)(pian)(pian)材料有(you)：工業純(chun)鈦(tai)TAl，用(yong)于海水(shui)或其(qi)它腐蝕性介(jie)質(zhi)(zhi)(zhi)；多種不銹鋼，用(yong)于淡水(shui)、飲用(yong)水(shui)、油類(lei)及(ji)其(qi)它非腐蝕性介(jie)質(zhi)(zhi)(zhi)。

在波紋板片的(de)密(mi)(mi)(mi)封(feng)槽上裝有密(mi)(mi)(mi)封(feng)墊片，密(mi)(mi)(mi)封(feng)墊片設(she)計成(cheng)雙道(dao)密(mi)(mi)(mi)封(feng)結(jie)構，并且有信(xin)號(hao)孔。當(dang)介質如從(cong)道(dao)密(mi)(mi)(mi)封(feng)泄(xie)露時，可(ke)從(cong)信(xin)號(hao)孑L泄(xie)出設(she)備(bei)之外，便能及早發現問(wen)題加以解決，不(bu)會造成(cheng)兩種介質的(de)混合。密(mi)(mi)(mi)封(feng)墊片可(ke)根據不(bu)同的(de)流體和操作(zuo)溫(wen)度選用不(bu)同的(de)膠種。

板式換熱器的技術優勢(shi)和(he)特點(dian)：

1、傳(chuan)熱系(xi)(xi)數高：傳(chuan)熱板片上的(de)(de)特殊波(bo)紋(wen)設計，可使(shi)流(liu)體在極低的(de)(de)流(liu)速(su)下產(chan)(chan)生(sheng)強烈的(de)(de)湍(tuan)流(liu)，湍(tuan)流(liu)的(de)(de)自(zi)凈效(xiao)應(ying)又可防止污垢(gou)的(de)(de)產(chan)(chan)生(sheng)，使(shi)得(de)板式換熱器的(de)(de)傳(chuan)熱系(xi)(xi)數為管(guan)殼式換熱器的(de)(de)3-5倍。

2、經濟(ji)性：相(xiang)同(tong)換熱量的前提下，與管殼式比較：投資少(shao)、運行費用(yong)低、維修費用(yong)低。

3、可調(diao)整(zheng)性(xing)：只需(xu)增加(jia)和減(jian)少板片即可滿足工(gong)藝(yi)過(guo)程改變的需(xu)求。

4、結構緊湊(cou)：在相(xiang)同換熱量的前提下，占用(yong)空(kong)間僅為管(guan)殼式的1／2一l／3。

5、易于潔洗(xi)維修。
