於上述情形下,如圖1中的一循環所示,由所述廢水於氣液分離後產生的所述分離液體,將會最後流入第一換熱器10中以作為與一新廢水(即,自第一換熱器組10之入水口新流入的廢水)進行上述預熱反應的熱源之一。In the above situation, as shown in a cycle in Figure 1, the separated liquid produced by the gas-liquid separation of the wastewater will finally flow into the

於上述情形下,如圖2所示,早先被導入的所述廢水將可先藉由第一加熱器110中的熱源之換熱而被預熱;然後,再依次藉由與第二加熱器120和第二換熱器組20之蒸發器210中的熱源之換熱,達到一個部份汽化/或全部汽化的狀態;最後,便可藉由氣液分離裝置50的分離成為可作為第二換熱器組20之熱源之一的分離氣體及可作為第一換熱器組10之熱源之一的分離液體。In the above situation, as shown in Figure 2, the wastewater introduced earlier will be preheated first by exchanging heat with the heat source in the first heater 110; and then, in turn, by exchanging heat with the second heater 110. 120 and the heat source in the
進一步地,所述分離液體於第一換熱器組10放出熱量後,其將可基於與在第一換熱器組10吸收熱量的新廢水的混合,而一同流入第二換熱器組20之蒸發器210進行次一階段的汽化反應。Further, after the separated liquid releases heat in the first
更進一步地,當所述分離氣體含有第一氣體時,其將可作為蒸發器210的熱源而於依次經過過濾裝置40的過濾及鼓風機30的增壓後,與上述經混合的新廢水於蒸發器210中進行熱交換,並與之混合。又,當所述分離氣體含有第二氣體時,第二氣體將可作為前述回收水之蒸氣態,而在冷凝器220放出熱量後凝結成為液態,並自第二加熱器120的出水口離開本機械式蒸氣再壓縮處理系統1。Furthermore, when the separated gas contains the first gas, it can be used as a heat source for the
值得一提的是,當所述分離氣體含有第二氣體時,所述第二氣體將可於冷凝器220的凝結後,繼續於第二加熱器120中,與自第一加熱器110之入水口新流入的廢水進行二次熱交換,使得前述回收水可以更低的溫度離開本機械式蒸氣再壓縮處理系統1,而有效降低對環境的污染(例如:避免優氧化現象)。It is worth mentioning that when the separated gas contains the second gas, the second gas will continue to be in the second heater 120 after condensation in the

如圖3所示,於預熱處理時,約50°C廢水依次經過第一加熱器110的換熱及第二加熱器120的換熱而升溫至約80°C ~90°C,並隨後經過第一槽G1流入蒸發器210進行汽化處理。於汽化處理時,已升溫之廢水自第一氣體及/或能量供應器2提供的熱能吸收熱量而再次升溫形成約105°C ~110°C的蒸氣氣體,汽化後的廢水以高溫低壓形式流入氣液分離裝置50分離成為約101°C ~110°C的第一氣體、約101°C ~110°C的第二氣體及約100°C的分離液體。As shown in Figure 3, during the preheating process, the approximately 50°C wastewater is heated to approximately 80°C ~ 90°C through the heat exchange of the first heater 110 and the second heater 120 in sequence, and then It flows into the
又如圖3所示,在約100°C的分離液體回流入第一加熱器110與新導入的廢水進行換熱時,即完成一循環;且在第一氣體依次經過過濾裝置40的過濾及鼓風機30的加壓而以約110°C ~120°C之高溫高壓形式流入蒸發器210與該預熱後的新廢水進行換熱時,即完成另一循環;以及在第二氣體以約101°C ~110°C之高溫低壓形式流入冷凝器220與該預熱後的新廢水進行換熱,再以約100°C的液態形式流入第二加熱器120與再次新導入的廢水進行換熱,從而可以約50°C的液態形式自第二加熱器120的出水口排出,即完成再一循環。As shown in Figure 3, when the separated liquid of about 100°C flows back into the first heater 110 to exchange heat with the newly introduced wastewater, a cycle is completed; and when the first gas is filtered and filtered by the
