In the embodiment of the utility model, the central axis A of the fan 14 coincides with the spiral axis B of the spiral structure 114, so that the steam can flow uniformly in the condensation structure 1, and uneven stress in the condensation structure 1 caused by overlarge or undersize air pressure at one side is avoided.

As shown in fig. 10-13, specifically, the fan 14 includes a fan blade 141 disposed in a spiral manner, and the spiral direction of the spiral structure 114 is the same as the spiral direction of the fan blade 141 of the fan 14, so that the hot steam sprayed from the steam outlet spiral cover 13 and the cold air generated by the fan 14 can be guaranteed to collide and mix, and then enter the spiral channel 1141 under the action of wind pressure of the fan 14.

In the embodiment of the present utility model, the spiral direction of the spiral structure 114 and the spiral direction of the fan blade 141 of the fan 14 are both positive spirals.

Specifically, the steam outlet spiral cover 13 is provided with a spiral rib 131 for spirally spraying the heat supply steam, and the spiral direction of the spiral rib 131 is opposite to the spiral direction of the fan blade 141 of the fan 14.

In the embodiment of the present utility model, the spiral direction of the spiral bone 131 is reverse spiral.

In the embodiment of the utility model, the spiral rib 131 is arranged, so that hot steam is spirally sprayed when being sprayed. By arranging the spiral direction of the spiral rib 131 opposite to the spiral direction of the fan blade 141 of the fan 14, the direction of hot steam sprayed out from the steam outlet spiral cover 13 is just opposite to the direction of cold air, so that collision can be generated at the moment, and the hot steam can be fully mixed with the cold air to realize rapid condensation.

With continued reference to fig. 13, for ease of understanding, embodiments of the present utility model will be described herein with respect to a process for condensing steam in the condensing structure 1. When in use, high-temperature steam a enters the steam guide pipe 12 from the steam inlet 1131, flows to the steam outlet spiral cover 13 along the extending direction of the steam guide pipe 12, and is subjected to primary cooling when flowing in the steam guide pipe 12, so that the temperature of steam sprayed out of the steam outlet spiral cover 13 is slightly lower. The high-temperature steam a is spirally sprayed to the air mixing cavity 1111 under the action of the spiral rib 131 of the steam outlet screw cap 13. The fan 14 continuously operates and sucks cold air e into the air mixing cavity 1111 from the outside, and since the spiral direction of the spiral rib 131 is opposite to the spiral direction of the fan blades 141 of the fan 14, the high-temperature steam a just collides with the cold air e to be fully mixed when being ejected from the spiral rib 131 in a spiral manner, so as to form medium-high-temperature steam b. Since the spiral direction of the spiral structure 114 is the same as the spiral direction of the fan blades 141 of the fan 14, the mixed medium-high temperature steam b enters the spiral channel 1141 of the spiral structure 114 under the action of the fan 14. The medium-high temperature steam b is further cooled to form medium-temperature gas c when flowing in the spiral channel 1141, collides with the inner wall of the spiral channel 1141 to form condensed water f, the medium-temperature gas c continuously flows along the spiral channel 1141 to be further cooled, and finally the low-temperature gas d is formed to be discharged from the steam exhaust port 1132 to the outside. The condensed water f flows out of the exhaust port 1132 partly through the spiral passage 1141 by the self gravity and the air flow in the spiral passage 1141, and flows out of the exhaust port 1132 partly to the bottom through the drain side groove 117.
