The working principle and the using flow of the utility model are as follows: first, the devices are connected in sequence, the power piece and the energy supply device are connected, and the starting device starts to use:
1. the circulating cold coal is compressed by the compressor 400 to become high-temperature high-pressure gaseous cold coal, the cold coal is subjected to heat exchange with liquid inlet sewage through the condenser 500 to become relatively low-temperature high-pressure gaseous cold coal, the liquid inlet sewage obtains the energy of the cold coal, and the relatively high-temperature liquid enters the evaporation tank 100 to be circularly sprayed.
2. The sewage is sprayed to increase the contact area with the air dried at low temperature (relatively dried), and after the sewage exchanges heat with the air dried at low temperature, the water in the sewage is brought into the air dried. The moisture content of the low-temperature dry air becomes high, and the low-temperature dry air becomes high-temperature wet air after heat exchange. After the heat exchange of the dry air and the sewage spray convection, the water is taken away, and the water vapor content of the dry air reaches saturation at the temperature to become high-temperature wet air.
3. After passing through the demisting net of the evaporation tank 100, the high-temperature moist air goes to the condensation tank 200, and is sprayed and cooled by relatively low-temperature condensed water or tap water, so that the high-temperature moist air is cooled, the temperature is reduced, the moisture content is also reduced, water vapor is also cooled and condensed, the water is discharged outside and becomes relatively low-temperature dry air.
4. After the running water and the high-temperature moist air exchange heat by convection, the temperature of the condensed water cooled and condensed is higher than the temperature of the cold coal passing through the expansion valve 301, and the condensed water enters the evaporator 300 to exchange heat with the cold coal in a partition way, which is equivalent to evaporating a refrigerant, and the cold coal takes away the heat in the condensed water to carry out heating and gasification, so that the energy of the cold recovery end of the heat pump is effectively utilized. The cold coal is then passed to the compressor 400 where it is converted to a high temperature and high pressure gas to release energy to the condenser.
Finally, the concentrated solution after concentration directly enters a centrifuge 700, the dried sludge produced by drying treatment is packed and bagged from the rear end through a screw conveyor 800, and the produced mother solution is mixed with the sewage of the inlet liquid and continuously enters the system for concentration circulation.
