[0023] Example 2: Please refer to Figures 1 to 8 As shown, based on the embodiment 1, the present invention provides a technical solution: a collecting tank 15 is welded and fixed to the inner wall of the inner lower end of the intake pipe 1, and a manifold 16 is installed at one end of the collecting tank 15. The condensed water on the inner wall of the intake pipe 1 is collected through the collecting tank 15 and then discharged through the manifold 16. The inner wall of the intake pipe 1 is rotatably mounted with a guide plate 14 through a fixed plate 11. The middle part of the guide plate 14 is rotatably mounted with an adjusting electric rod 13. The adjusting electric rod 13 is rotatably mounted on the inner wall of the intake pipe 1 through a rotating shaft, and the piston rod of the adjusting electric rod 13 is rotatably mounted on the guide plate 14. According to The size of the intake vortex needs to be adjusted by adjusting the angle of the guide plate 14 by adjusting the electric rod 13, so as to better block and collect the condensate centrifuged by the air flow; the surface of the guide plate 14 is provided with a guide hole 12, and the shape of the guide plate 14 is set to be a semicircular ring, and two guide plates 14 are symmetrically installed on the inner side of the intake pipe 1, which is convenient for installation on the inner side of the intake pipe 1 when in use; the shape of the collection tank 15 is set to be circular, and the collection tank 15 is installed on the inner wall of the intake pipe 1 at an angle, and the conduit 16 is connected to the lowest point of the collection tank 15, which is convenient for fully collecting condensed water and draining it out for collection when in use.

[0024] The guide plate 14 and the collection trough 15 of the above-mentioned technical solution are used. When in use, the airflow is limited and guided by the guide plate 14, and the condensed water is guided by the guide plate 14 and collected through the collection trough 15, and then guided to the position of the collection mechanism 4 through the manifold 16 for collection. When in use, the angle of the guide plate 14 can be adjusted by adjusting the electric rod 13, so that the condensed water can be fully guided and collected while guiding the airflow, preventing unevaporated water droplets from entering the compressor.

[0025] Further, see Figures 1 to 8 The collecting mechanism 4 includes a collecting box 41 welded to the bottom of the lower end of the air intake pipe 1, and a liquid accumulation groove 42 is provided at the inner bottom of the air intake pipe 1. The condensed water flowing down is collected through the liquid accumulation groove 42, and the lower end of the confluence pipe 16 corresponds to the position of the liquid accumulation groove 42. The lower end of the liquid accumulation groove 42 is connected to the collecting box 41, and the water collected in the liquid accumulation groove 42 flows into the collecting box 41 for storage; a support frame 43 is welded at the connection between the inner bottom of the liquid accumulation groove 42 and the collecting box 41, and a silicone sheet 44 is installed on the lower side of the support frame 43. The middle part of the silicone sheet 44 is fixed to the support frame 43 by screws, and the edge of the silicone sheet 44 covers the connection between the collecting box 41 and the liquid accumulation groove 42. The silicone sheet 44 is pressed open by water gravity and flows into the collecting box 41 for collection, which is more convenient to clean during collection.

[0026] The collection mechanism 4 using the above technical solution collects condensed water through the collection box 41 when in use, and seals it by adhering the silicone sheet 44 to the inner wall of the collection box 41. When there is water, the silicone sheet 44 is pressed open and the water flows into the collection box 41 for collection, making it convenient to collect the condensed water when in use.

[0027] The working principle and use process of the present invention are as follows: when in use, the filtered airflow enters the guide tube 21 at the gas turbine inlet, and passes through the guide plate 28 in the form of a vortex to reach the position of the spray mechanism 3. The spray mechanism 3 covers the entire cross-section through the honeycomb distributed layout of the piezoelectric ceramic ultrasonic nozzle 33, so as to fully mix with the airflow passing through the vortex, and realizes rapid evaporation and heat absorption cooling through ultra-fine droplets, thereby avoiding water mist from entering the compressor and eroding. When in use, the motor 24 can be used to drive the adjustment bevel gear 25 to rotate, and the transmission bevel gear 26 can be used to adjust the angle of the rotating shaft 27 and the air guide plate 28 to adjust the vortex effect generated, and When the piezoelectric ceramic ultrasonic nozzle 33 is damaged after long-term use, it is only necessary to open the maintenance sealing door 36 to disassemble and repair the piezoelectric ceramic ultrasonic nozzle 33 on the spray fixing seat 32, which is more convenient during maintenance. During use, the condensed water on the inner wall of the intake pipe 1 is collected through the collection tank 15 and then discharged through the manifold 16. At the same time, the angle of the guide plate 14 is adjusted by adjusting the electric rod 13 as needed. While guiding the airflow, the water droplets centrifuged by the vortex are adsorbed and collected in the collection tank 15. The condensed water flowing down is collected through the liquid accumulation tank 42, and then the silicone sheet 44 is pressed open by water gravity to flow into the collection box 41 for collection, which is more convenient to clean during collection.
