The hot humid air passes through the condenser 5-1 through the internal channel formed by the box body 1, is cooled by the surface of the condenser 5-1 under the action of circulating cooling water, and the moisture of the hot humid air is condensed on the surface of the condenser 5-1 and falls into the condensed water collecting tank 6-12 at the lower part of the box body under the action of gravity. The hot and humid air is changed into cold and dry air after being dehydrated, and continuously enters the fan 3 for circulating work.
After the condensed water collected by the condensed water collecting tank 6-12 reaches a certain height, the water pump 6-1 is started, the condensed water is pumped into the filtering system from the water inlet 6-8, and then enters the PP filter element 6-2, the activated carbon filter element 6-3 and the block activated carbon filter element 6-4 in sequence to filter impurities.

The effluent filtered by the reverse osmosis filter element 6-6 enters the bacteriostatic activated carbon filter element 6-7, further removes trace pollutants, becomes standard-reaching drainage, is discharged into the environment through the water outlet pipe 6-9, and the wastewater in the reverse osmosis filter element 6-6 flows back to the condensate water collecting tank 6-12 through the wastewater return pipe 6-10 and is continuously filtered by the filter system.
Once the condensed water pollutants in the condensed water collecting tank 6-12 exceed the water inlet standard of the filtering system, the water outlet 6-11 is opened, and the filtered concentrated liquid is discharged. The concentrated solution is stored to a certain amount and then enters the waste liquid tank 2-6 again for re-concentration and evaporation. When the waste water solution in the waste liquid tank 2-6 reaches a certain level, such as more crystals, the control display unit 7-2 stops the operation of the device, opens the partition plate 2-7, takes out the concentrated solution in the waste liquid tank 2-6, and pours the concentrated solution into a special container for collection.
Secondly, the cooling circulating water in the heat exchange pipe of the condenser 5-1 cools the hot and humid air, is heated by the cooling circulating water and enters the air cooler 5-5 through the circulating water pipe 5-6. Under the action of the fan 5-4, cooling air is firstly sucked from the perforated mesh enclosure 5-8, then enters circulating cooling water in the cooling pipe of the air cooler 5-5, and is blown out from the perforated mesh enclosure 5-7. The cooled circulating cooling water enters a pressure maintaining water tank 5-3 and then enters a condenser 5-1 through a circulating water pipe 5-6 under the action of a circulating water pump 5-2 to continuously cool the hot humid air. A certain amount of purified water is filled into the pressure maintaining water tank 5-3 in advance, so that the stable circulating water amount in the condensation unit is ensured.
Finally, the inside of the box body 1 is divided into independent spaces by the partition board 9 to be placed in the control unit, the control display unit 7-2 in the control unit is used for displaying the working state of each electric appliance and the operation parameters of each part of the device, the electric appliance control 7-1 can be controlled through panel operation, and the system, the starting and stopping of the electric appliance, the fault display and the like are achieved.
