沈陽酸洗廢水(shui)蒸發器(qi)如果污水(shui)的(de)溫(wen)度(du)低于(yu)其本身的(de)沸點的(de)話，并(bing)且直接位于(yu)溶(rong)(rong)(rong)液表面(mian)上方(fang)(fang)溶(rong)(rong)(rong)劑蒸汽(qi)壓大于(yu)溶(rong)(rong)(rong)液上方(fang)(fang)空間中同(tong)一蒸汽(qi)的(de)分壓，但小于(yu)總壓時，污水(shui)蒸發器(qi)中就會發生(sheng)氣化反應，由(you)污水(shui)的(de)表面(mian)、在(zai)不(bu)同(tong)的(de)溫(wen)度(du)下進行。但由(you)于(yu)氣化過程不(bu)能保證(zheng)由(you)溶(rong)(rong)(rong)液中強烈地排除(chu)溶(rong)(rong)(rong)劑，使得溶(rong)(rong)(rong)液的(de)濃縮緩慢，所以很(hen)少應用。
