MVR蒸發(fā)成套設備

其工作原理:用離心蒸汽壓縮機或其它蒸汽壓縮機械,將全部二次蒸汽進(jìn)行壓縮,使其物理性能達到加熱蒸汽的要求,把它用作加熱蒸汽,這種蒸發(fā)工藝,僅在開(kāi)機時(shí),需輸入新鮮蒸汽,正常運行后,再不用輸入新蒸汽,也沒(méi)有(或極少)的二次蒸汽需要冷凝,因此MVR蒸發(fā)極大地節約了蒸汽,但是用電較多。

Its working principle: using centrifugal compressor steam or other vapour compression machinery, all the secondary steam is compressed, make its physical properties meet the requirements of heating steam, it is used to heat the steam, the evaporation process, only when switched on, need to input the new fresh steam, normal after the operation, don't have to enter a new steam again, also have no (or very few) need secondary steam condensate, accordingly. MVR evaporation greatly saves steam, but consumes more electricity.

MVR板式蒸發(fā)裝置與4效蒸發(fā)裝置效益對比表:

(工藝參數: 10t/h ,進(jìn)汽75度,排氣85度, 10度溫升)

111

一、10噸MVR板式蒸發(fā)裝置預計投資費用在400萬(wàn)左右

二、10噸蒸發(fā)裝置年運行費用比10噸MVR板式蒸發(fā)裝置年運行費用多出316.08萬(wàn)

三、因此10噸MVR板式蒸發(fā)裝置的總投資比多效蒸發(fā)裝置年運行減省的費用將在,1.3年回收即15個(gè)月( 400萬(wàn)/316.08萬(wàn)*12個(gè)月)

注:各地的汽、電價(jià)不一樣,工藝不- -樣,產(chǎn)生的回收期不同,具體以最終的方案而定。
