[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] See also Figure 1-7 As shown, an ammonia waste gas purification device includes a filter box 2, the two ends of the filter box 2 are respectively connected to the intake pipe 1 and the exhaust pipe 3, and an adsorption core 8 is arranged in the filter box 2; the adsorption core 8 includes a hollow bracket 12, a support plate frame 13 and an adsorption fiber cloth 16, there are two support plate frames 13, and a plurality of hollow brackets 12 are horizontally arranged between the two support plate frames 13, and the plurality of hollow brackets 12 are arranged in an array in the vertical direction, and the adsorption fiber cloth 16 is sequentially wound around the plurality of hollow brackets 12 in an S shape and arranged between the two support plate frames 13; a strip hole 14 is opened at a position of the support plate frame 13 corresponding to the hollow bracket 12, and the hollow bracket 12 is slidably connected to the support plate frame 13 through the strip hole 14, and the sliding directions of the two adjacent hollow brackets 12 are opposite.

[0030] When installing the absorption fiber cloth 16, the absorption fiber cloth 16 is passed between the two support plates 13, and then a plurality of hollow brackets 12 are sequentially pushed into between the two support plates 13 from both sides of the hollow brackets 12 along the strip holes 14. Under the limit of the hollow brackets 12, the absorption fiber cloth 16 is arranged in an S shape. By providing a plurality of hollow brackets 12 slidably connected to the support plates 13, the absorption fiber cloth 16 is arranged more conveniently.

[0031] When in use, the exhaust gas is sent into the filter box 2 by the fan through the air inlet pipe 1, and the exhaust gas enters from the strip holes 14 on one side of the adsorption inner core 8. When passing through the gaps of the adsorption fiber cloth 16, the adsorption fiber cloth 16 adsorbs the ammonia in the exhaust gas. After adsorption treatment, the exhaust gas is discharged from the strip holes 14 on the other side of the adsorption inner core 8.

[0032] In some embodiments, see Figure 4 and 5As shown, a U-shaped groove 15 is provided at one end of the strip hole 14, and the U-shaped grooves 15 at the ends of two adjacent strip holes 14 are staggered and distributed at both ends of the U-shaped groove 15, and support columns 17 are fixedly connected to both ends of the hollow bracket 12, one of the support columns 17 is slidably connected to the support plate frame 13 through the strip hole 14, and the other support column 17 is limited by the U-shaped groove 15.

[0033] When installing the absorption fiber cloth 16, the absorption fiber cloth 16 is passed between the two support plate frames 13, and then the multiple hollow brackets 12 are pushed in sequence from top to bottom along the strip holes 14 from both sides of the hollow bracket 12 between the two support plate frames 13. When pushing the hollow bracket 12, one of the support columns 17 of the hollow bracket 12 is slid along the strip holes 14 to the limit position, and the other support column 17 is placed in the U-shaped groove 15 corresponding to the strip hole 14. The U-shaped groove 15 supports and limits this end of the hollow bracket 12. This connection method does not require the hollow bracket 12 to be removed, and there is no need to align the hollow bracket 12 when pushing, which makes it more convenient to push the hollow bracket 12.

[0034] In some embodiments, see Figure 6 As shown, one end of the strip-shaped hole 14 extends to one side of the support plate frame 13 to form a socket 18 , and the sockets 18 of two adjacent strip-shaped holes 14 face opposite directions.

[0035] When installing the adsorption fiber cloth 16, the adsorption fiber cloth 16 is passed between the two support plates 13, and then the multiple hollow brackets 12 are sequentially pushed into the two support plates 13 from both sides of the hollow bracket 12 along the strip hole 14. When pushing the hollow bracket 12, one end of the hollow bracket 12 is pushed into the strip hole 14 from the socket 18, and the strip hole 14 supports both sides of the hollow bracket 12. This connection method can completely remove the hollow bracket 12, making it more convenient to maintain and clean. Among them, the width of the hollow bracket 12 should be greater than the spacing between the two support plates 13, so that the strip hole 14 can support and limit the hollow bracket 12.

[0036] In order to prevent the hollow bracket 12 from sliding, side plates 6 are provided on both sides of the filter box 2, and elastic sealing plates 7 for limiting the hollow bracket 12 are fixedly connected to the inner side of the side plates 6. While limiting the hollow bracket 12 by the elastic sealing plate 7, the sealing of both sides can be improved to prevent the exhaust gas from passing through the two sides of the adsorption inner core 8 and affecting the purification effect. Among them, the side plates 6 are fixed to the frame of the filter box 2 by bolts.

[0037] In order to regenerate the adsorbent fiber cloth 16, a liquid supply pipe 5 is fixedly connected to the inner side of the top of the filter box 2, and a plurality of spray heads 4 are evenly arranged on the liquid supply pipe 5. A liquid discharge port 9 is provided at the bottom of the filter box 2. The desorption liquid is sprayed by the spray head 4, and the desorption liquid gradually seeps downward, so that the adsorbent fiber cloth 16 is regenerated layer by layer to ensure the desorption effect. Finally, the desorption liquid is discharged from the liquid discharge port 9.

[0038] Specifically, the adsorption fiber cloth 16 is an existing functional fiber cloth for ammonia adsorption.

[0039] The adsorption principle is: NH3+RCOOH→R-COONH4;

[0040] The regeneration principle is: R-COONH4+H2SO4→R-COOH+(NH4)2SO4.

[0041] In some embodiments, the distance between two adjacent hollow brackets 12 matches the thickness of the adsorption fiber cloth 16. The adsorption fiber cloth 16 is limited by the two hollow brackets 12 to prevent the adsorption fiber cloth 16 from vibrating during ventilation.

[0042] Specifically, the hollow support 12 includes two layers of support nets 19, and a support column for controlling the gap is provided between the two layers of support nets 19. By providing a support column between the two layers of support nets 19, the spacing of the support nets 19 can be controlled to prevent the support nets 19 from being deformed.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
