水處理中什(shen)么是板式(shi)換熱器?

 與各(ge)種管(guan)式換(huan)熱(re)(re)(re)(re)(re)(re)器不(bu)(bu)同，板(ban)(ban)(ban)(ban)(ban)式換(huan)熱(re)(re)(re)(re)(re)(re)器是通過(guo)傳熱(re)(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban)片(pian)(pian)(pian)(pian)換(huan)熱(re)(re)(re)(re)(re)(re)的(de)(de)(de)。冷(leng)熱(re)(re)(re)(re)(re)(re)流(liu)(liu)(liu)體分別在板(ban)(ban)(ban)(ban)(ban)片(pian)(pian)(pian)(pian)的(de)(de)(de)兩(liang)側(ce)流(liu)(liu)(liu)過(guo)進行傳熱(re)(re)(re)(re)(re)(re)。傳熱(re)(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban)片(pian)(pian)(pian)(pian)由0.5~3mm的(de)(de)(de)金屬薄板(ban)(ban)(ban)(ban)(ban)壓制成型，材質(zhi)有(you)不(bu)(bu)銹鋼、黃銅或(huo)鋁(lv)合金等。為(wei)增強剛度、避免變形(xing)，一般將板(ban)(ban)(ban)(ban)(ban)片(pian)(pian)(pian)(pian)壓成波紋形(xing)。波紋既增大(da)了(le)傳熱(re)(re)(re)(re)(re)(re)面積，又增強了(le)流(liu)(liu)(liu)體的(de)(de)(de)湍流(liu)(liu)(liu)程度。板(ban)(ban)(ban)(ban)(ban)片(pian)(pian)(pian)(pian)的(de)(de)(de)四個角上(shang)各(ge)開(kai)一孔(kong)，作為(wei)冷(leng)熱(re)(re)(re)(re)(re)(re)流(liu)(liu)(liu)體的(de)(de)(de)進出(chu)口(kou)。板(ban)(ban)(ban)(ban)(ban)片(pian)(pian)(pian)(pian)四周及(ji)孔(kong)周圍壓有(you)密封(feng)墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)槽，可貼人密封(feng)墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)。墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)可根據流(liu)(liu)(liu)體流(liu)(liu)(liu)動的(de)(de)(de)需要(yao)來(lai)放置，從而(er)起到允許或(huo)阻止(zhi)流(liu)(liu)(liu)體進入(ru)板(ban)(ban)(ban)(ban)(ban)面之(zhi)間通道的(de)(de)(de)作用。按傳熱(re)(re)(re)(re)(re)(re)需要(yao)將若(ruo)干塊傳熱(re)(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban)片(pian)(pian)(pian)(pian)排列(lie)在支架上(shang)，由壓板(ban)(ban)(ban)(ban)(ban)借壓緊(jin)螺桿壓緊(jin)后，相鄰板(ban)(ban)(ban)(ban)(ban)間就形(xing)成了(le)流(liu)(liu)(liu)體通道。藉助(zhu)墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)的(de)(de)(de)恰當布(bu)置，使(shi)冷(leng)、熱(re)(re)(re)(re)(re)(re)流(liu)(liu)(liu)體在傳熱(re)(re)(re)(re)(re)(re)板(ban)(ban)(ban)(ban)(ban)片(pian)(pian)(pian)(pian)的(de)(de)(de)兩(liang)側(ce)流(liu)(liu)(liu)過(guo)進行傳熱(re)(re)(re)(re)(re)(re)。不(bu)(bu)同厚(hou)度的(de)(de)(de)墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)可以調(diao)節板(ban)(ban)(ban)(ban)(ban)間距(一般4~6mm)，即調(diao)節流(liu)(liu)(liu)量(liang)。

板(ban)式換熱器的主要(yao)優點(dian)是在低(di)(di)流(liu)速下即能達到(dao)湍流(liu)，傳熱效率比列管式換熱器高，設備緊湊，操作(zuo)靈活性(xing)大，板(ban)片(pian)制(zhi)造、檢修及(ji)清洗(xi)都(dou)比較方(fang)便。其缺點(dian)主要(yao)是處理量(liang)不(bu)大，同時受板(ban)片(pian)剛度及(ji)墊片(pian)性(xing)能的限制(zhi)，允許的操作(zuo)壓(ya)力和溫度都(dou)不(bu)能太高，操作(zuo)板(ban)壓(ya)一(yi)般(ban)低(di)(di)于1.5MPa，最(zui)高不(bu)超過2MPa。用(yong)合成橡膠墊時操作(zuo)溫度應低(di)(di)130℃，用(yong)壓(ya)縮石(shi)棉墊片(pian)應低(di)(di)250℃。
