[0024] Specifically, the shell 1 can play a fixed support role for the motor 2. When the motor 2 is turned on, the motor 2 drives the connecting column 3 to rotate, and the rotation of the connecting column 3 drives the two bevel gears 4 to rotate synchronously, and the rotation of the bevel gears 4 also drives the bevel gears 5 and 6 to rotate synchronously. At the same time, the rotation of the bevel gears 5 and 6 drives the rotating columns 7 and 8 to rotate in the inner wall of the shell 1. The shell 1 can support the rotating columns 7 and 8, and the rotation of the rotating column 8 drives the spur gear 9 to rotate, and the rotation of the spur gear 9 also drives the spur gear 10 to rotate in the opposite direction. In turn, the rotation of the spur gear 10 drives the sleeve 11 to rotate in the opposite direction. At the same time, the rotating column 7 and the sleeve 11 are fixedly connected with the support disc 12. The rotation of the rotating column 7 drives the support disc 12 to rotate in the positive direction, and the rotation of the sleeve 11 drives the support disc 12 to rotate in the opposite direction, so that the spray head 13 can rotate coaxially in the opposite direction to spray, the droplet distribution is more uniform, the gas-liquid contact area is expanded, and the gas-liquid mixing effect is greatly enhanced, thereby improving the efficiency of desulfurization and denitration reaction.

[0025] With reference to Figure 1 The upper surface of the shell 1 is fixedly connected with a water pump 14. The input end of the water pump 14 is fixedly connected with a material barrel 15. The outer wall of the material barrel 15 is fixedly connected to the outer wall of the shell 1. The output end of the water pump 14 is fixedly connected to the inner wall of the rotating column 7.

[0026] Specifically, the shell 1 can play a fixed support role for the water pump 14.

[0027] With reference to Figure 3 The outer wall of the shell 1 is fixedly connected with a fixed frame 16. The outer wall of the fixed frame 16 is fixedly connected with a motor 17. The output end of the motor 17 is fixedly provided with a rotating disc 18. The outer wall of the rotating disc 18 is fixedly connected with a fixed column 19. The outer wall of the fixed column 19 is rotatably connected with a transmission plate 20. The outer wall of the transmission plate 20 is rotatably connected with a sliding plate 21.

The upper surface of the sliding plate 21 is fixedly connected with a brush 23. The upper surface of the brush 23 is arranged on the lower surface of the spray head 13.

[0028] Specifically, the shell 1 can play a fixed support role for the fixed frame 16, and the fixed frame 16 can play a fixed support role for the motor two 17. When the motor two 17 is started, the motor two 17 drives the rotating disc 18 to rotate, and the rotation of the rotating disc 18 drives the fixed column 19 to rotate around the rotating disc 18, and the rotation of the fixed column 19 also drives the transmission plate 20 to rotate. At the same time, the rotation of the transmission plate 20 also drives the sliding plate 21 to slide on the inner wall of the support frame 22. The support frame 22 can support the sliding plate 21 to ensure the stability of the sliding plate 21. The sliding of the sliding plate 21 also drives the brush 23 to slide on the surface of the nozzle 13. The brush 23 can clean the by-products (such as calcium sulfate and calcium nitrate) generated by the reaction of the absorbent and the pollutants, prevent the deposition from wearing the nozzle 13, prolong the service life of the nozzle 13, and reduce the replacement and maintenance cost of the equipment.

[0029] Working principle: when the device is needed, first, the staff opens the motor one 2, and the motor one 2 drives the connecting column 3 to rotate. The rotation of the connecting column 3 drives the bevel gear one 4 to rotate, and the rotation of the bevel gear one 4 also drives the bevel gear two 5 and the bevel gear three 6 to rotate. At the same time, the rotation of the bevel gear two 5 and the bevel gear three 6 also drives the rotating column one 7 and the rotating column two 8 to rotate. The rotation of the rotating column two 8 also drives the spur gear one 9 to rotate, and the rotation of the spur gear one 9 also drives the spur gear two 10 to rotate. At the same time, the rotation of the spur gear two 10 also drives the sleeve 11 to rotate. The rotation of the sleeve 11 and the rotating column one 7 drives the respective support discs 12 to rotate in opposite directions, thereby driving the nozzle 13 to rotate coaxially in opposite directions. When the nozzle 13 needs to be cleaned, first, the staff opens the motor two 17, and the motor two 17 drives the rotating disc 18 to rotate. The rotation of the rotating disc 18 drives the fixed column 19 to rotate, and the rotation of the fixed column 19 also drives the transmission plate 20 to rotate. At the same time, the rotation of the transmission plate 20 also drives the sliding plate 21 to slide on the inner wall of the support frame 22. The sliding of the sliding plate 21 also drives the brush 23 to reciprocatingly slide on the surface of the nozzle 13, thereby achieving the effect of cleaning the nozzle 13. That is, the device not only can make the liquid droplets more uniformly distributed by driving the nozzle 13 to rotate coaxially in opposite directions, expand the gas-liquid contact area, and improve the desulfurization and denitration reaction efficiency, but also can prevent the deposition from wearing the nozzle 13 by reciprocatingly cleaning the nozzle 13, prolong the service life of the nozzle 13, and reduce the replacement and maintenance cost of the equipment.
