[0024] As Figures 1 to 4 The backflow pipe 5 is arranged in an inclined manner.

[0025] The un-gasified liquid chlorine can flow along the inner wall of the spiral pipe 2 and reach the end of the reflux pipe 5 under the action of gravity, so that the gasification effect of the refluxed liquid chlorine is improved.

[0026] As shown in Figures 1 to 4 The liquid inlet pipe 9 is arranged at the end of the gasifier shell 1 close to the chlorine inlet pipe 3, and the liquid outlet pipe 10 is arranged at the end of the gasifier shell 1 close to the gas outlet pipe 4.

[0028] As shown in Figures 1 to 4 The liquid inlet pipe 9 and the liquid outlet pipe 10 are arranged at the bottom end of the gasifier shell 1 and communicate with the inside of the gasifier shell 1.

[0029] The hot water flowing into the liquid inlet pipe 9 can efficiently heat the refluxed liquid chlorine, so that the gasification of the refluxed liquid chlorine is realized.

[0030] As shown in Figures 1 to 4 The first bevel gear 11 is fixedly arranged at one end of the rotating rod 7, the fixed block 12 is fixedly arranged at the end of the gasifier shell 1 close to the first bevel gear 11, the rotating shaft 13 is rotatably arranged at the middle of the fixed block 12 through a bearing, the impeller 14 is fixedly arranged at the top end of the rotating shaft 13 and penetrates through the gas outlet pipe 4, the rotating shaft 13 and the gas outlet pipe 4 are rotatably connected through a mechanical seal, the impeller 14 is arranged in the inside of the gas outlet pipe 4, the second bevel gear 15 is fixedly arranged at the bottom end of the rotating shaft 13, and the second bevel gear 15 is rotatably connected with the first bevel gear 11.

At the same time, when the liquid chlorine passes through the end of the spiral pipe 2, the unvaporized liquid chlorine flows along the inner wall of the spiral pipe 2 and under the action of gravity to the inside of the return pipe 5. Since the end of the return pipe 5 is located at the position of the liquid inlet pipe 9, the temperature of the liquid at the end of the return pipe 5 is higher, which can more efficiently heat and gasify the returning liquid chlorine, improving the overall gasification effect of the liquid chlorine.
