Pipeline connects having heaters 7, and the heater 7 is connected with crystallizer 8, the crystallizer 8 by pipeline respectively with the one-level
Heat exchanger 2 connects with the heat exchange pipeline of the secondary heat exchanger 3, the heat exchange of the first-class heat exchanger 2 and the secondary heat exchanger 3
Pipeline is connected with foul water system.
During work, water pump 1 extracts waste water and sequentially enters first-class heat exchanger 2 and secondary heat exchanger 3, reaches two after waste water heating
The boiling point of chloromethanes, the waste water after heating enter gas-liquid separator 4, and the gas of gaseous dichloromethane from gas-liquid separator 4 goes out
Mouth enters condenser 5, and dichloromethane liquefies and enters dichloromethane recycling can 6, and remaining waste water is from liquid in gas-liquid separator 4
Outlet enters heater 7, and hot waste water enters crystallizer 8 after heating, and the hot water discharged after crystallization enters first-class heat exchanger 2 and two
The heat exchange pipeline of level heat exchanger 3 heats to waste water above, makes full use of waste heat, the waste water after heat exchange enters sewage discharge
System is further processed.
