The bottom end of the evaporation barrel 1 is fixedly connected to a chassis 18. The chassis 18 stores the poured alkali mud. A heat storage tray 19 is provided at the bottom of the chassis 18. The heat storage tray 19 stores the absorbed heat and provides heat for the chassis 18 to continue evaporating. The bottom end of the heat storage tray 19 is fixedly connected to a metal support 15. The metal support 15 is a metal with good thermal conductivity. The bottom end of the pillar 15 is fixedly connected to a heat conducting plate 14, which absorbs the heat of the converter for conduction. A crystallization barrel 2 is provided on the top of the evaporation barrel 1. The crystallization barrel 2 is the storage area for solids and gases in the entire device. A condensing iron sheet 3 is fixedly connected inside the crystallization barrel 2. The temperature of the condensing iron sheet 3 changes rapidly and has good heat dissipation. It can be cooled quickly under the blowing of the heat dissipation fan 16. Two air pipes 5 are fixedly connected to the top of the condensing iron sheet 3. The air pipe 5 discharges the purified gas. The outer wall of the air pipe 5 is fixedly connected to a heat dissipation fan 16, which continuously cools the condensing iron sheet 3.

[0026] The outer wall of the evaporation barrel 1 is fixedly connected with a fixed iron sheet 7, which fixes the feed port 8. Four suction cups 9 are fixedly connected to one side of the fixed iron sheet 7, and the feed port 8 is fixedly connected to one side of the fixed iron sheet 7. The suction cups 9 fix the feed port 8 to the fixed iron sheet 7.

[0027] The bottom end of the evaporation barrel 1 is fixedly connected to a water outlet 10, and the periphery of the water outlet 10 is fixedly connected to a valve 11. The valve 11 controls the water outlet 10. After the sedimentation is completed, the valve 11 is opened to discharge the purified liquid.

[0028] The top of the crystallization barrel 2 is fixedly connected to an air pipe 5 , and the periphery of the air pipe 5 is fixedly connected to an exhaust port 6 .

[0029] A filter 17 is fixedly connected to the top of the evaporation barrel 1 , and the crystals that fall after the condensation iron sheet 3 is pulled are collected by the filter 17 .
