In contain low boiling point volatile matter when, low boiling point volatile matter can evaporate together with water vapour and be entered by first pipe 8 in evaporator 3
Compressor 5, after then entering evaporator heating chamber 4 by second pipe 9, water vapour becomes condensed water by the 4th pipe after releasing heat
Road 10 is discharged into condensate liquid preheater 1, and low boiling point volatile matter can not become condensed water discharge, this part low boiling point volatile matter
As fixed gas, fixed gas can gather in evaporator heating chamber 4, can make the compressor outlet of compressor 5 with the increase of amount
51 pressure rise, and material causes evaporation capacity to gradually reduce because quantity of steam lacks in evaporator 3, until because of evaporator heating chamber
The fixed gas that will not become condensed water in 4 is more and more so that material can not evaporate, 52 gas of compressor inlet of compressor 5
It is less and less, and the pressure of compressor outlet 51 is more and more big.Eventually lead to whole device be forced it is out of service.In order to avoid
Such situation occurs, and the setting third pipeline 11 in evaporator heating chamber 4 that has no alternative is connected into vacuum pump 6, will not become cold
The fixed gas of condensate is pumped by vacuum pump 6.And at this time because fixed gas and water vapour mix, it can not be kept away when being aspirated with vacuum pump 6
Exempt from together to take useful water vapour away, cause device thermal loss, while needing that water vapour is continuously replenished to maintain equipment
Normal operation leads to the increase of energy consumption.
