There is a movable baffle on the front of the high-temperature evaporation zone. When the evaporation is completed, the baffle can be opened to discharge the impurities remaining in the high-temperature evaporation zone. The opening on the right side of the high-temperature evaporation zone is connected to the pipe 3 171. The pipe 3 A motor 2 17 is fixedly connected to the bottom of 171, and the motor 2 17 drives the rotating rod 172 inside the pipe 3 171, and the rotating rod 172 drives the fan blade 173 to rotate, so that the gas treated with high temperature is sucked into the pipe 3 171, and finally enters the cooling device. The high-temperature gas is cooled and liquefied by the condenser 18 in the cooling device, and the liquefied liquid is discharged through the pipe 2 123 at the bottom of the cooling device and enters the collecting box 3 12. The collecting box 3 12 then passes the pipe 1 121 into the collecting box 4 122, and finally the water pump 1221 re-enters the liquid in the collecting box 4 122 into the interior of the filter box 1, thereby completing the cycle and achieving the reuse of resources.
