1.主換熱器熱端溫差偏大景象某廠12000m3爪空分設備接納分子篩吸附凈化、增壓透平膨大、規整填料上塔及全精餾無氫制氮外壓 縮流程。自空分設備開車以來，用戶不斷反應主換熱器熱端溫差過大，廣東半容積式熱交換器廠家此中一組換熱器有7℃一8℃的溫 差。通過種種調理花招，液體產量仍達不到條約要求的計劃值。檢查空分設備流程圖和精餾塔總圖發明，6臺主換熱器(El一E6)分兩組散布，分子篩吸附器出口空 氣通過正流空氣閥Vln和vllZ分別進人El一E3和E4一E6兩組換熱器。兩組換熱器之間的熱端溫差可哄騙 v川和vllZ閥來調理，優質半容積式熱交換器每組內3個(ge)單(dan)位(wei)之間靠冷箱內配管來(lai)平衡氣(qi)流的(de)散布。增壓空氣(qi)出主換(huan)熱器各(ge)單(dan)位(wei) 有中部、底(di)部兩個(ge)抽(chou)口，進膨大機的(de)空氣(qi)溫度由(you)中部抽(chou)口總(zong)管閥(fa)(fa)V31和底(di)部抽(chou)口總(zong)管閥(fa)(fa)V犯來(lai)調理。返流 氣(qi)體只要(yao)通過(guo)各(ge)自總(zong)管上的(de)調理閥(fa)(fa)來(lai)調理流量。
