[0029] Furthermore, the steam delivery component includes an air pump 8, the top of the air pump 8 is fixedly connected to an air supply pipe 9, the inner wall of the air supply pipe 9 on the side away from the air pump 8 is provided with an annular groove, the side of the air supply pipe 9 away from the air pump 8 is rotatably sleeved on the outer wall of the connecting pipe 6, a limiting ring 7 is rotatably connected to the inner wall of the annular groove of the air supply pipe 9, and is movably connected to the air supply pipe 9 through the connecting pipe 6 and the limiting ring 7, so that the rotation of the heat exchange tube 2 is not affected while delivering gas.

[0036] By arranging the heat exchange tube 2 and the heat conducting plate 3, the heat exchange area is increased and the raw material solution is stirred, so as to avoid the solution from sticking to the bottom and make the heat in the solution evenly distributed, thereby solving the problem that the steam heat exchange pipe is only in contact with the bottom area of ​​the raw material solution, the heat exchange area is small, the heat exchange is insufficient, and the evaporation efficiency is low.
