[0032] Working principle: The staff first let the wastewater enter the evaporation box 1 through the water inlet 8, then set the temperature of the heating element 7, and then start the motor 14. The motor 14 drives the rotating rod 15 and the scraper 18 to stir the wastewater. When the wastewater reaches the boiling point, water vapor will be generated. The water vapor will be sent to the inner cavity above the partition 16 through the air inlet pipe 2, the air outlet pipe 5 and the steam jet pump. This is the water vapor slowly cooling into water in this area, and then the water will enter the water storage tank 10 through the water outlet 9. At this time, the valve 20 of the sewage valve 19 is opened to discharge and collect the crystals after distillation.
