MVR蒸发成套设备

其工作原理:用离心蒸汽压缩机或其它蒸汽压缩机械,将全部二次蒸汽进行压缩,使其物理性能达到加热蒸汽的要求,把它用作加热蒸汽,这种蒸发工艺,仅在开机时,需输入新鲜蒸汽,正常运行后,再不用输入新蒸汽,也没有(或极少)的二次蒸汽需要冷凝,因此MVR蒸发极大地节约了蒸汽,但是用电较多。

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板式蒸发装置与4效蒸发装置效益对比表:

(工艺参数: 10t/h ,进汽75度,排气85度, 10度温升)

111

一、10吨MVR板式蒸发装置预计投资费用在400万左右

二、10吨蒸发装置年运行费用比10吨MVR板式蒸发装置年运行费用多出316.08万

三、因此10吨MVR板式蒸发装置的总投资比多效蒸发装置年运行减省的费用将在,1.3年回收即15个月( 400万/316.08万*12个月)

注:各地的汽、电价不一样,工艺不- -样,产生的回收期不同,具体以最终的方案而定。
