[0035] Embodiment 1:

[0036] With reference to Figures 1-8 , comprising a cover 1, further comprising: a first evaporation chamber 7, a second evaporation chamber 8, a third evaporation chamber 9, all arranged in the cover 1; a tube bundle 20 arranged in the first evaporation chamber 7, the second evaporation chamber 8, the third evaporation chamber 9 respectively; a heating gas pipe 33 communicated at the top of the first evaporation chamber 7; a feeding pipe 3 communicated at the top end of the first evaporation chamber 7, the feeding pipe 3 is arranged in the first evaporation chamber 7 and communicated with the tube bundle 20 at one end; a fixed rod 26 is fixedly connected in the tube bundle 20, a spiral auger blade 28 is arranged on the fixed rod 26, a turbine blade 29 is rotatably connected at the bottom of the fixed rod 26, and a cleaning rod 30 is arranged on the turbine blade 29.

[0038] When the material enters the tube bundle 20, part of the material is hung on the inner wall of the tube bundle 20 to form a uniform film on the inner wall of the tube bundle 20, the high-temperature gas has a good heating effect on the uniform film on the inner wall, and part of the material spirally descends along the auger blade 28, because the auger blade 28 and the fixed rod 26 are both hollow designs, the auger blade 28 is communicated with the fixed rod 26, the fixed rod 26 is fixedly connected in the tube bundle 20 through the rod, the high-temperature gas enters the auger blade 28 and the fixed rod 26 to heat the material placed thereon, and the tube bundle 20 is heated to heat the material inside and outside the tube bundle 20, and the heating effect is good;

[0039] Because the temperature of the material entering the upper part of the tube bundle 20 is lower, the temperature of the material entering the lower part of the tube bundle 20 is higher, most of the material evaporates at this position, and there are many crystal bodies attached to the inner wall of the lower part of the tube bundle 20, which affects the heating effect of the material, and even blocks the tube bundle 20;

[0040] Due to the material flowing along the inner wall of the tube bundle 20 and the auger blade 28, when flowing onto the turbine blade 29, has a certain impact force, thereby driving the turbine blade 29 to rotate, the turbine blade 29 further disperses the material, so that the area of the material in contact with heat is larger, and the evaporation effect is better, and at the same time, the rotating turbine blade 29 drives the cleaning rod 30 to rotate, and the cleaning rod 30 cleans the middle and lower parts of the tube bundle 20, removes the crystals attached to the inner wall of the tube bundle 20, avoids the influence of the crystals on the heating effect of the high-temperature gas on the material, and also avoids the crystals from blocking the tube bundle 20.

[0041] Embodiment 2:

[0045] The material treated by the first evaporation chamber 7, the second evaporation chamber 8 and the third evaporation chamber 9 is discharged into the condensate water pipe 6 through the water vapor outlet 24.

[0046] The material placed in the storage chamber 25 at the bottom of the first evaporation chamber 7 flows into the tube bundle 20 in the second evaporation chamber 8 through the second pipeline 11 for heating treatment, the material placed in the storage chamber 25 at the bottom of the second evaporation chamber 8 flows into the third evaporation chamber 9 through the third pipeline 12, and finally the material is discharged through the discharge pipe 5.

[0049] In the application, the high-temperature gas is finally discharged from the outer cover 1 through the exhaust pipe 4, and the through slot 22 allows the high-temperature gas to pass through, so that the pipe bundle 20 is heated comprehensively;

[0050] The material conveyed in the feeding pipe 3 first falls on the fixed disc 15, and then flows on the discharging disc 16 along the edge of the fixed disc 15, so that the material is prevented from directly rushing into the pipe bundle 20, thereby forming a water column in the pipe bundle 20 and affecting the heating effect;

[0051] The first taper block 18 and the second taper block 19 are provided with a gap corresponding to the discharging opening 17, so that the material on the discharging disc 16 can be sprayed more uniformly to the inner wall of the pipe bundle 20 through the gap, so that the material can be attached to the inner wall of the pipe bundle 20 as much as possible, thereby forming a uniform film on the inner wall of the pipe bundle 20, and the heating effect of the high-temperature gas on the pipe bundle 20 is better.
