[0033] The working principle and usage process of this utility model are as follows: During the wastewater treatment process, the wastewater inside the storage tank 2 is guided into the treatment tank 1. The wastewater inside the treatment tank 1 is heated by the heating mechanism 17. After heating, the water in the wastewater will evaporate, causing the salt in the wastewater to crystallize. The evaporated gas will be guided into the heat exchange mechanism 6, which will heat the inside of the storage tank 2, facilitating the recycling of residual heat in the exhaust gas. During the evaporation process, the waste liquid is stirred by the stirring mechanism 14, ensuring that the waste liquid is heated evenly. At the same time, when the material is discharged, the stirring mechanism 14 is controlled to rotate in the opposite direction, which will drive the cleaning mechanism 25 to rotate and clean the inner wall of the treatment tank 1. Meanwhile, the screw rod 27 will push the material towards the discharge pipe 18, facilitating the rapid discharge of the material.
