A mounting groove 12 is opened on the surface of the right side of the cooling box 2. The mounting groove 12 is located inside the cooling groove 10 and the circulation groove 11. The bottom wall of the mounting groove 12 is fixedly connected to a centrifugal pump 13. The centrifugal pump 1 3 is connected to the input end of the cooling box 2 with an upper connecting pipe 14, the top of the upper connecting pipe 14 extends to the interior of the circulation tank 11 and is connected thereto, the output end of the centrifugal pump 13 is connected to the lower connecting pipe 15, the bottom end of the lower connecting pipe 15 extends to the interior of the refrigeration tank 10 and is connected thereto, a left circulation groove 16 is provided on the left side of the surface of the cooling box 2, and the left circulation groove 16 is connected to the circulation groove 11, and right circulation grooves 17 are provided at both ends of the right side surface of the cooling box 2, and the right circulation grooves 17 extend to the interior of the refrigeration tank 10 and are connected thereto, a reaction chamber 18 is fixedly connected to the top of the cooling box 2, a cooling cavity 19 is provided in the interlayer of the reaction chamber 18, and the cooling cavity 19 is connected to the left circulation groove 16 and the right circulation groove 17, the front of the reaction chamber 18 is connected to a gas inlet pipe 20, the top of the reaction chamber 18 is connected to a gas outlet pipe 21, and several rows of quartz tubes 22 and hollow aluminum tubes 23 are staggered inside the reaction chamber 18.

[0022] refer to Figures 1 to 5 A stirring motor 24 is fixedly connected to the right side of the cooling box 2. The input end of the stirring motor 24 passes through the interior of the refrigeration tank 10 and is fixedly connected to a rotating rod 25. A stirring blade 26 is fixedly connected to the surface of the rotating rod 25.

[0023] As a technical optimization solution of the present invention, by setting the stirring motor 24, the stirring motor 24 is started to rotate the rotating rod 25, and the rotation of the rotating rod 25 drives the stirring blade 26 to rotate to mix the cooling water inside the refrigeration tank 10 evenly, so that the cooling water can fully carry and circulate the cold energy generated by the refrigeration plate 4, thereby further improving the cooling efficiency.

The bearing 28 is sleeved on the surface of the output end of the stirring motor 24 and fixedly connected thereto. The circular groove 27 is a sealed bearing.

There are several heat dissipation grooves 33 .

[0031] As a technical optimization solution of the present invention, the setting of the heat dissipation groove 33 increases the air circulation inside the installation groove 12, so that the heat discharged by the centrifugal pump 13 can be quickly discharged to the outside of the cooling box 2 through the heat dissipation groove 33, further improving the heat dissipation efficiency of the centrifugal pump 13.

[0032] The working principle and use process of the present invention are as follows: when in use, the user first injects cooling water through the hole on the top of the reaction chamber 18, plugs the hole after it is filled, and passes the gas to be purified into the interior of the reaction chamber 18 through the gas inlet pipe 20. Then, after the quartz tube 22 and the hollow aluminum tube 23 are connected to an external pulse power supply, plasma will be generated between the quartz tube 22 and the hollow aluminum tube 23. The gas can be purified by the plasma when passing through and discharged from the gas outlet pipe 21. Since a large amount of heat will be generated when the plasma is generated, it is necessary to start the refrigeration plate 4 to refrigerate the cooling water inside the refrigeration tank 10, and start the stirring motor 24 to rotate the rotating rod 25. The rotation of the rotating rod 25 drives the stirring blade 26 to rotate to mix the cooling water inside the refrigeration tank 10 evenly, so that the cooling water can fully carry the cold energy generated by the refrigeration plate 4 for circulation, and then start the centrifugal pump 13 to circulate the cooling cavity 19 and the circulation The water flow inside the annular groove 11 is pumped into the interior of the refrigeration groove 10 for cooling. At the same time, the water flow inside the refrigeration groove 10 will flow to the internal circulation of the cooling chamber 19 through the right circulation groove 17 to cool the reaction chamber 18. When the refrigeration plate 4 continues to refrigerate, the heat dissipation motors 8 on both sides of its bottom are started to drive the heat dissipation blades 9 to rotate. The rotation of the heat dissipation blades 9 on the right will blow the external air into the interior of the through groove 3, increasing the air circulation and blowing the heat from the bottom of the refrigeration plate 4 to the left, while the rotation of the heat dissipation blades 9 on the left will pump the air inside the through groove 3 to the left side of the cooling box 2, further increasing the circulation speed of the air inside the through groove 3, so that the heat from the bottom of the refrigeration plate 4 is quickly discharged. At the same time, the blowing motor 31 is started to rotate the blowing blades 32. The blowing blades 32 rotate to blow out an airflow sufficient to dissipate heat from the centrifugal pump 13 and discharge it from the centrifugal pump 13 to the outside of the cooling box 2.
