蒸發式冷凝器

蒸發式(shi)冷凝(ning)器是(shi)傳(chuan)統的(de)(de)(de)涼水(shui)(shui)(shui)塔和(he)管(guan)(guan)(guan)(guan)(guan)(guan)殼式(shi)冷凝(ning)器的(de)(de)(de)一種(zhong)組(zu)合改進設(she)備，主(zhu)要(yao)由換熱(re)裝(zhuang)(zhuang)置、水(shui)(shui)(shui)循環系(xi)統及風(feng)(feng)機(ji)三部(bu)(bu)分(fen)(fen)組(zu)成，傳(chuan)熱(re)部(bu)(bu)分(fen)(fen)多為蛇形管(guan)(guan)(guan)(guan)(guan)(guan)組(zu)。制(zhi)(zhi)冷劑(ji)蒸汽(qi)流(liu)(liu)(liu)過管(guan)(guan)(guan)(guan)(guan)(guan)內，管(guan)(guan)(guan)(guan)(guan)(guan)外(wai)是(shi)空氣和(he)噴淋水(shui)(shui)(shui)的(de)(de)(de)混合物作為冷卻用流(liu)(liu)(liu)體。制(zhi)(zhi)冷劑(ji)蒸汽(qi)由上部(bu)(bu)進氣口(kou)進入，在管(guan)(guan)(guan)(guan)(guan)(guan)內自(zi)上而(er)下逐漸凝(ning)結放出熱(re)量(liang)，通過管(guan)(guan)(guan)(guan)(guan)(guan)壁傳(chuan)給管(guan)(guan)(guan)(guan)(guan)(guan)外(wai)的(de)(de)(de)水(shui)(shui)(shui)膜，再通過管(guan)(guan)(guan)(guan)(guan)(guan)外(wai)冷卻水(shui)(shui)(shui)的(de)(de)(de)蒸發將熱(re)量(liang)傳(chuan)遞給空氣也就是(shi)利用水(shui)(shui)(shui)的(de)(de)(de)汽(qi)化熱(re)，帶走制(zhi)(zhi)冷劑(ji)冷凝(ning)過程放出的(de)(de)(de)冷凝(ning)熱(re)量(liang)蒸發式(shi)冷凝(ning)器的(de)(de)(de)換熱(re)管(guan)(guan)(guan)(guan)(guan)(guan)一般用光管(guan)(guan)(guan)(guan)(guan)(guan)，但(dan)隨著對換熱(re)管(guan)(guan)(guan)(guan)(guan)(guan)的(de)(de)(de)不斷(duan)研究，出現了橢圓管(guan)(guan)(guan)(guan)(guan)(guan)、異形管(guan)(guan)(guan)(guan)(guan)(guan)、波紋管(guan)(guan)(guan)(guan)(guan)(guan)和(he)交(jiao)變(bian)曲面波紋管(guan)(guan)(guan)(guan)(guan)(guan)等新型盤管(guan)(guan)(guan)(guan)(guan)(guan)。噴淋水(shui)(shui)(shui)量(liang)以(yi)能全(quan)部(bu)(bu)潤濕盤管(guan)(guan)(guan)(guan)(guan)(guan)表面、形成連(lian)續水(shui)(shui)(shui)膜為，以(yi)獲得大的(de)(de)(de)傳(chuan)熱(re)系(xi)數，并減少水(shui)(shui)(shui)垢。蒸發式(shi)冷凝(ning)器根據風(feng)(feng)機(ji)安(an)裝(zhuang)(zhuang)的(de)(de)(de)位置不同(tong)主(zhu)要(yao)有吸(xi)風(feng)(feng)式(shi)、鼓風(feng)(feng)式(shi)和(he)上吸(xi)風(feng)(feng)橫流(liu)(liu)(liu)-順流(liu)(liu)(liu)式(shi)三種(zhong)。
