對冷凍干燥機中共熔點的概念理解
冷凍(dong)干(gan)(gan)燥機采用降溫結露(lu)的(de)(de)原理,主要由熱(re)(re)交(jiao)換(huan)(huan)系統(tong)、制冷系統(tong)和電(dian)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)控制系統(tong)三部(bu)分組(zu)成。壓(ya)縮空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)首先進(jin)(jin)入預冷卻器(qi)(qi)進(jin)(jin)行(xing)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)-氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)或(huo)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)-水的(de)(de)熱(re)(re)交(jiao)換(huan)(huan),除去一部(bu)分熱(re)(re)能(neng),然后(hou)進(jin)(jin)入冷熱(re)(re)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)交(jiao)換(huan)(huan)器(qi)(qi),和已經從蒸(zheng)發(fa)器(qi)(qi)出(chu)來被冷卻到壓(ya)力露(lu)點的(de)(de)冷空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)進(jin)(jin)行(xing)熱(re)(re)交(jiao)換(huan)(huan),使壓(ya)縮空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)溫度(du)(du)(du)進(jin)(jin)一步降低(di)。之后(hou)壓(ya)縮空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)進(jin)(jin)入蒸(zheng)發(fa)器(qi)(qi),與制冷劑進(jin)(jin)行(xing)熱(re)(re)交(jiao)換(huan)(huan),壓(ya)縮空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)溫度(du)(du)(du)降至0-8℃,空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)中的(de)(de)水份在此(ci)溫度(du)(du)(du)下析出(chu),通過(guo)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)水分離(li)器(qi)(qi)分離(li)后(hou),經過(guo)自動排(pai)水器(qi)(qi)排(pai)出(chu)。而干(gan)(gan)燥的(de)(de)低(di)溫空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)則進(jin)(jin)入冷熱(re)(re)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)交(jiao)換(huan)(huan)器(qi)(qi)進(jin)(jin)行(xing)熱(re)(re)交(jiao)換(huan)(huan),溫度(du)(du)(du)升高(gao)后(hou)輸出(chu)。對于共(gong)熔點的(de)(de)概念(nian)關...
