[0026] The output port 105 and the input port 111 are communicated with external pipes by the rotary connecting sleeve 104. In use, the evaporation liquid is added from the inlet port 107, the heat exchange water is input from the input port 111, and then flows into the heat exchange pipe group from the flow shaft 117, and then flows to the other flow shaft 117, and finally flows out from the output port 105. During the flow of the heat exchange water, the heat of the heat exchange water is transferred to the evaporation liquid in the evaporation tank through the heat exchange pipe group, so as to increase the temperature of the evaporation liquid and make it evaporate, and then be sucked away from the outlet port 106.

[0027] The driving unit is arranged to make the heat exchange pipe rotate in the evaporation tank, so that the heat exchange pipe 112 stirs the evaporation liquid in the evaporation tank, so that the evaporation liquid is uniformly heated, and the evaporation effect is improved.

[0028] Embodiment 2:

[0029] The driving mechanism of the embodiment is further expanded on the basis of the above-mentioned embodiments, and specifically as shown in Figures 1-2 The driving mechanism includes the driven gear 108, the driving gear 109, and the motor 110. The driven gear 108 is installed on one of the flow shafts 117. The driving gear 109 is installed on the motor 110, and the driving gear 109 is engaged with the driven gear 108.

[0030] During the evaporation operation, the motor 110 is started, the motor 110 drives the driving gear 109 to rotate, the driving gear 109 drives the driven gear 108, and the driven gear 108 drives the flow shaft 117 to rotate the heat exchange pipe group.

[0031] The other parts of the embodiment are the same as those of the above-mentioned embodiments, and will not be described again.

[0032] Embodiment 3:

[0033] The heat exchange pipe group of the embodiment is further expanded on the basis of the above-mentioned embodiments, and specifically as shown in Figure 4 , Figure 6 The number of the heat exchange pipes 112 in each layer of the heat exchange pipe unit is the same, and the heat exchange pipes 112 in adjacent heat exchange pipe units are arranged staggeredly.

[0034] The heat exchange pipe unit with variable diameter makes the number of the heat exchange pipes 112 as many as possible and as compact as possible, and improves the heat exchange efficiency. The purpose of the staggered arrangement is to increase the distance between adjacent heat exchange pipes 112, so as to ensure that the heat of the heat exchange pipes can be dissipated as much as possible, and further improve the heat exchange efficiency.

[0035] The other parts of the embodiment are the same as those of the above-mentioned embodiments, and will not be described again.

[0036] Embodiment 4:

The outer spiral blade 113 rotates in the opposite direction to the inner spiral blade 114. The heat exchange tube 112 is segmented, and a connecting sleeve 115 is provided on one segment of the heat exchange tube 112. The connecting sleeve 115 is used to connect two segments of the heat exchange tube 112. The segmented arrangement of the heat exchange tube 112 is for the convenience of installing the outer spiral blade 113 and the inner spiral blade 114.

[0038] When the heat exchange tube assembly rotates, it automatically drives the outer spiral blade 113 and the inner spiral blade 114 to rotate. At this time, one of the outer spiral blade 113 and the inner spiral blade 114 drives the evaporating liquid to flow upward, and the other drives the evaporating liquid to flow downward, thus forming a cycle. This circulates and stirs the evaporating liquid at different heights in the evaporating tank, improving the uniformity of the evaporating liquid's heating.

[0039] Furthermore, multiple scraper blades 116 are installed on the outer spiral blade 113, and the scraper blades 116 are attached to the inner wall of the evaporator. When the outer spiral blade 113 rotates, the scraper blades 116 rotate synchronously, and at this time the scraper blades 116 will scrape the inner wall of the evaporator to prevent scale from forming on the tank wall.

[0040] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.
