[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Reference Figure 1-Figure 3, An embodiment of the present invention is: a spray device for a desulfurization tower in a thermal power plant, comprising a tower body 1 and a water inlet pipe 2, wherein a filter box 3 is fixedly connected to the outer wall of the water inlet pipe 2, the bottom end of the filter box 3 is fixedly connected to the top of the tower body 1, and is slidably connected to the inner wall of the installation frame 4, and a card block 6 is slidably connected to both the upper and lower sides of the inner wall of the installation frame 4, and a card slot is provided on both the upper and lower sides of the inner wall of the filter box 3, and the card block 6 matches the shape of the card slot, and a lever 7 is fixedly connected to the front end of the card block 6, and a spring 8 is fixedly connected to the opposite end of the card block 6, and the opposite end of the spring 8 is respectively fixedly connected to the upper and lower ends of the inner wall of the installation frame 4, and a filter plate 5 is fixedly connected to the inner wall of the installation frame 4,

[0026] Specifically, after the filter plate 5 has filtered impurities for a long time, the filter plate 5 may be filled with impurities, thereby clogging the water inlet pipe 2. At this time, the levers 7 on both sides of the front end of the filter box 3 can be moved to make the levers 7 drive the block 6 to move toward the middle, so that the block 6 is disengaged from the slot on the filter box 3, and then the handle on the installation frame 4 is used to pull out the installation frame 4, so that it drives the filter plate 5 to be pulled out, and then a new filter plate 5 is replaced and installed in the filter box 3.

[0027] Reference Figure 4-Figure 6 A motor 10 is fixedly connected to the top of the tower body 1, and a turntable 11 is fixedly connected to the driving end of the motor 10. The outer wall of the turntable 11 is rotatably connected to the top of the inner wall of the tower body 1. A control rod 12 is fixedly connected to the rear side of the bottom end of the turntable 11. The opposite ends of the left and right movable plates 14 are fixedly connected to the control plate 13. The outer wall of the control rod 12 is slidably connected in the control plate 13. The tops of the left and right movable plates 14 are fixedly connected to slide plates 19. The top of the slide plates 19 is slidably connected to the top of the inner wall of the tower body 1. The inner walls of the left and right movable plates 14 are rotatably connected to connecting pipes 15. The outer wall of the connecting pipe 15 is fixedly connected to a gear 16. The outer wall of the gear 16 is meshedly connected to a toothed plate 17. The top of the toothed plate 17 is fixedly connected to the top of the inner wall of the tower body 1. The bottom end of the connecting pipe 15 is fixedly connected to a nozzle 18, and the nozzle 18 is located inside the tower body 1. Two hoses 9 are fixedly connected to the outer wall of the water inlet pipe 2, and the bottom end of the hose 9 is rotatably connected to the top of the connecting pipe 15.

[0028] Specifically, the desulfurizer in the water inlet pipe 2 enters the connecting pipe 15 through the hose 9, the hose 9 passes through the top of the tower body 1, and the desulfurizer in the connecting pipe 15 is sprayed into the tower body 1 through the nozzle 18. When the motor 10 drives the movable plates 14 on both sides to move through the turntable 11, the slide plate 19 on the movable plate 14 supports the movable plate 14. When the movable plate 14 drives the connecting pipe 15 to move, because the top of the connecting pipe 15 is connected to the hose 9, and the hose 9 rotates on the top of the connecting pipe 15, the movement of the connecting pipe 15 does not affect the desulfurizer entering the nozzle 18.

[0029] Working principle: When in use, the desulfurizer will enter from the water inlet pipe 2, pass through the filter plate 5 in the filter box 3, the filter plate 5 will filter out impurities, the desulfurizer will pass through the filter plate 5 and enter the connecting pipe 15 from the hose 9, and finally enter the nozzle 18. At this time, the motor 10 is started, the motor 10 drives the turntable 11 to rotate, the turntable 11 drives the control rod 12 to rotate with the turntable 11, the control rod 12 slides in the control board 13, and makes the control board 13 move left and right, the control board 13 drives the moving plates 14 on both sides to move left and right, thereby driving the connecting pipe 15 to move left and right, the connecting pipe 15 will drive the gear 16 to move while moving and fixing, so that the gear 16 rotates under the action of the tooth plate 17, thereby driving the connecting pipe 15 to rotate, and the connecting pipe 15 drives the nozzle 18 to rotate. This combination of horizontal movement and rotational movement enables the nozzle 18 to achieve multi-dimensional dynamic spraying in the tower body 1, which greatly increases the coverage of the desulfurizer in the tower body 1.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
