A first sealing gland 9 and a second sealing gland 14 are respectively provided at both ends of the aluminum alloy profile 1. The first sealing gland 9 and the second sealing gland 14 seal the compressed air chamber 15, the pressure water chamber 16 and the heating chamber 17. 7 is sealed at both ends to form independent sealed chambers; a water inlet 11 and an air inlet 13 are provided on the first sealing cover 9, the water inlet 11 is connected to the pressure water chamber 16, and the air inlet 13 is connected to the compressed air chamber 15; along the extension direction of the aluminum alloy profile 1, a plurality of the ultrasonic nozzles 6 are detachably installed on the aluminum alloy profile 1, the nozzle inner cavity passes through the pressure water chamber 16, the tail of the nozzle inner cavity is connected to the compressed air chamber 15, a connecting hole 18 connected to the pressure water chamber 16 is provided on the nozzle inner cavity, and the head of the ultrasonic nozzle 6 is located on the outside of the aluminum alloy profile 1.

[0027] Based on the above technical solution, the aluminum alloy profile is integrally formed with high integration, strong ductility and good pressure resistance.

[0028] Furthermore, the pressure water chamber 16 is located between the compressed air chamber 15 and the heating chamber 17. The heating chamber 17 is opposite to the compressed air chamber 15 and the pressure water chamber 16 and is adjacent to the pressure water chamber 16.

[0030] Furthermore, the first sealing gland 9 is provided with a heating tape connection port 12 for allowing cables to pass through.

[0031] Furthermore, the aluminum alloy profile 1 has a profile outer plate and a profile inner plate, the profile outer plate encloses an internal space, and the profile inner plate divides the internal space into three unconnected chambers, namely, a compressed air chamber 15, a pressure water chamber 16, and a heating chamber 17.

[0038] Compressed air enters the compressed air chamber 15 from the air inlet 13. Pressurized water enters the pressure water chamber 16 from the water inlet 11. Compressed air enters the ultrasonic nozzle through the rear end of the nozzle. Pressurized water enters the nozzle through the annular hole in the middle of the nozzle and merges with the compressed air and is ejected from the nozzle. High-pressure water vapor passes through the nozzle and hits the cylinder at the head of the nozzle, causing it to break into 1-10 micron particles and be ejected with an effective distance of 1.5-2.5 meters. It then combines with pollutants in the air and falls under the influence of the back force.
