[0028] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0029] like Figure 1 and Figure 2 As shown, the basic embodiment of the present disclosure provides a liquid-gas conversion nozzle, including a liquid-gas conversion nozzle 3, and a plurality of protrusions are arranged on the inner wall of the liquid-gas conversion nozzle 3.

[0030] In order to facilitate understanding of the technical solution of the liquid-gas conversion nozzle disclosed in the present invention, the technical effects of the liquid-gas conversion nozzle disclosed in the present invention will be specifically described below with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2 As shown, a plurality of protrusions are arranged on the inner wall of the liquid-gas conversion nozzle 3. When the ammonia water enters the liquid-gas conversion nozzle 3, the ammonia water collides with the plurality of protrusions on the inner wall of the liquid-gas conversion nozzle 3, so that the activity of the ammonia water molecules is intensified, thereby improving the vaporization effect of the ammonia water.

[0032] like Figure 2 As shown, in some embodiments, the protrusions are arranged sequentially and symmetrically on the inner wall of the liquid-gas conversion nozzle 3, so that after the ammonia water enters the liquid-gas conversion nozzle 3, while the molecular activity of the ammonia water is intensified, the ammonia water is evenly vaporized due to the symmetrical and sequential arrangement of the protrusions on the inner wall of the liquid-gas conversion nozzle 3, thereby improving the vaporization effect of the ammonia water.

[0033] On the basis of the technical solution of the above-mentioned liquid-gas conversion nozzle in the present disclosure, the present disclosure also provides a high-efficiency liquid-gas conversion nozzle ammonia spray grid, which includes the liquid-gas conversion nozzle 3 and the ammonia main pipeline 1 described in any of the above-mentioned technical solutions, and a plurality of ammonia branch pipes 2 are arranged on the ammonia main pipeline 1, and a plurality of liquid-gas conversion nozzles 3 are arranged on each ammonia branch pipe 2.

[0034] In order to facilitate understanding of the technical solution of the high-efficiency liquid-gas conversion nozzle ammonia spraying grid disclosed in the present invention, the technical effects of the high-efficiency liquid-gas conversion nozzle ammonia spraying grid disclosed in the present invention will be specifically described below with reference to the accompanying drawings.

[0035] like Figure 1 As shown, it includes a liquid-gas conversion nozzle and an ammonia main pipeline 1 of any of the above technical solutions, a plurality of ammonia branch pipes 2 are arranged on the ammonia main pipeline 1, and a plurality of liquid-gas conversion nozzles 3 are arranged on each ammonia branch pipe 2. Ammonia water is introduced into each ammonia branch pipe 2 through the ammonia main pipeline 1, and each ammonia branch pipe 2 vaporizes and sprays the ammonia water through the plurality of liquid-gas conversion nozzles 3, thereby expanding the area where ammonia is sprayed, allowing ammonia to fully react with exhaust gas, and improving the utilization efficiency of ammonia.

[0036] like Figure 1 As shown, in some embodiments, each ammonia delivery branch pipe 2 is axially symmetrically arranged on the ammonia delivery main pipeline 1, so that the ammonia is sprayed more evenly in the reaction container, the exhaust gas in the reaction container reacts with the ammonia more fully, and the utilization efficiency of the ammonia is improved.

[0037] like Figure 1As shown, in some embodiments, the angles between each ammonia branch pipe 2 and the ammonia main pipeline 1 from the input end to the outside are different, so that each ammonia branch pipe 2 contacts a larger range in the reaction container, increasing the range of ammonia spraying, and the exhaust gas in the reaction container reacts more fully with the ammonia, thereby improving the utilization efficiency of the ammonia.

[0038] like Figure 1 As shown, in some embodiments, the angle between each ammonia branch pipe 2 and the ammonia main pipeline 1 decreases successively from the input end to the outside of the ammonia main pipeline 1, so that the ammonia branch pipes 2 can be arranged on the ammonia main pipeline 1 as much as possible to avoid the ammonia branch pipes 2 from offsetting each other due to different angles. As much ammonia branch pipes 2 as possible are arranged on the ammonia main pipeline 1 to increase the range of ammonia spraying, so that the exhaust gas in the reaction container reacts more fully with the ammonia, and the utilization efficiency of the ammonia is improved.

[0039] like Figure 1 As shown, in some embodiments, each liquid-gas conversion nozzle 3 is connected in series on each ammonia delivery branch pipe 2 at equal intervals, so that the liquid-gas conversion nozzle 3 is evenly arranged on the ammonia delivery branch pipe 2, which increases the range of ammonia spraying and makes the reaction between the exhaust gas and ammonia in the reaction container more sufficient and uniform, thereby improving the utilization efficiency of ammonia.

[0040] like Figure 1 As shown, in some embodiments, a plurality of main nozzles are provided on the ammonia main pipeline 1. By providing a plurality of main nozzles on the ammonia main pipeline 1, ammonia is sprayed to places where the ammonia main pipeline 1 cannot spray, thereby increasing the range of ammonia spraying, and the waste gas in the reaction container reacts more fully with ammonia, thereby improving the utilization efficiency of ammonia. Among them, the main nozzle can adopt the same nozzle structure as the liquid-gas conversion nozzle 3.

[0041] like Figure 1 As shown, a plurality of main nozzles are evenly arranged in series on the ammonia main pipeline 1, so that the ammonia is sprayed more evenly, the waste gas in the reaction container reacts with the ammonia more fully, and the utilization efficiency of the ammonia is improved.

[0042] On the basis of the above-mentioned technical solution of the high-efficiency liquid-gas conversion nozzle ammonia spraying grid, the present disclosure further provides a reaction container, which includes the high-efficiency liquid-gas conversion nozzle ammonia spraying grid of the above-mentioned technical solution.

[0043] In order to facilitate a deeper understanding of the technical concept and advantages of the present disclosure, the following Figure 1 to Figure 2 The present invention describes the relatively preferred and relatively comprehensive liquid-gas conversion nozzle and the structural form of the high-efficiency liquid-gas conversion nozzle ammonia spray grid and reaction container.

[0044] A plurality of ammonia branch pipes 2 are arranged on the ammonia main pipe 1, and a plurality of liquid-gas conversion nozzles 3 are arranged on the ammonia branch pipes 2. Ammonia water is transported to the plurality of ammonia branch pipes 2 through the ammonia main pipe 1, and a plurality of liquid-gas conversion nozzles 3 are arranged on the plurality of ammonia branch pipes 2. The ammonia water input into the plurality of ammonia branch pipes 2 is vaporized into ammonia gas through the plurality of liquid-gas conversion nozzles 3, thereby expanding the contact range of ammonia water with the exhaust gas in the reaction container, fully allowing ammonia water to react with the exhaust gas in the reaction container, and reducing the escape of ammonia water. A plurality of protrusions are arranged on the inner wall of the liquid-gas conversion nozzle 3, and the protrusions are sequentially and symmetrically arranged in the liquid-gas conversion nozzle 3, thereby accelerating the reaction of ammonia water in the liquid-gas conversion nozzle 3. Vaporization in the conversion nozzle 3, multiple ammonia branch pipes 2 are axially symmetrically arranged on the ammonia main pipeline 1, and the angles between each ammonia branch pipe 2 and the ammonia main pipeline 1 from the input end to the outside of the ammonia main pipeline 1 are different. The angles between each ammonia branch pipe 2 and the ammonia main pipeline 1 from the input end to the outside of the ammonia main pipeline 1 decrease successively, and each liquid-gas conversion nozzle 3 is connected in series on each ammonia branch pipe 2 at equal intervals in sequence. A plurality of main nozzles are arranged on the ammonia main pipeline 1, and the plurality of main nozzles are evenly arranged in series on the ammonia main pipeline 1, thereby increasing the range of ammonia spraying, and the exhaust gas in the reaction container reacts more fully with the ammonia, thereby improving the utilization efficiency of the ammonia.

[0045] It can be seen from the above description of the present disclosure that the present disclosure intensifies the activity of ammonia molecules and improves the vaporization effect of ammonia by sequentially and symmetrically arranging a number of protrusions on the inner wall of the liquid-gas conversion nozzle 3;

[0046] By providing a plurality of ammonia delivery branch pipes 2 and main nozzles, the range of ammonia spraying is increased, so that the waste gas in the reaction container reacts more fully with ammonia, thereby improving the utilization efficiency of ammonia.
