Description

Technical Field

[0001] This utility model relates to the technical field of denitrification ammonia spraying equipment, specifically a dual-mixing nozzle for denitrification ammonia spraying equipment. Background Technology

[0002] Denitrification ammonia injection equipment is widely used in various industrial emission sources, such as coal-fired power plants, glass manufacturing, and cement production, to reduce nitrogen oxide emissions and meet environmental standards. For example, Three Gorges New Materials completed the upgrade of its production line environmental protection system, implementing denitrification precision ammonia injection technology, and achieving ultra-low emissions.

[0003] The denitrification ammonia spraying equipment is assembled from various components. The dual-mixing nozzle is one such component. For example, Chinese patent discloses an external mixing dual-media atomizing nozzle, publication (announcement) number: CN103846172A, which includes: a feed pipe, a vortex guide plate, and a tangential guide. The feed pipe has a through liquid chamber, one end of which is the spray end and the other end is the liquid inlet end. The vortex guide plate is set at the inlet end of the feed pipe, and a liquid inlet hole is opened on the vortex guide plate. The tangential guide is sleeved on the outside of the feed pipe. The tangential guide includes a connecting part near the liquid inlet end and an air inlet part near the spray end. The inner diameter of the connecting part is smaller than the inner diameter of the air inlet part. The inner wall of the connecting part is tightly fitted with the outer wall of the feed pipe. A first gas chamber is formed between the inner wall of the air inlet part and the outer wall of the feed pipe. A guide groove for the gas medium to enter the first gas chamber is opened on the outer wall of the air inlet part. The external mixing dual-medium atomizing nozzle of this invention can increase the relative velocity of the liquid and gas media when they are ejected, thereby effectively reducing the atomization pressure to ensure the degree of atomization of the liquid and improve the absorption of the liquid by the tobacco material. The above-mentioned patent can effectively reduce the atomization pressure during use to ensure the degree of atomization of the liquid and improve the absorption of the liquid by the tobacco material. However, it cannot reduce the pressure when the internal pressure of the dual mixing nozzle is too high. This can lead to the nozzle pipe cracking and bursting when the internal water pressure of the dual mixing nozzle is too high, making it impossible to reduce the pressure of the dual mixing nozzle and affecting the service life of the nozzle.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4 As shown, the present invention provides a dual-mixing nozzle for a denitrification ammonia spraying equipment, comprising:

[0025] Dual-mixing nozzle 1;

[0026] Spray head distance control mechanism 2 is located inside the dual-mixing nozzle 1;

[0027] The pressure reducing mechanism 3 includes a connecting pipe 31. A plugging ring 32 is fixedly connected inside the connecting pipe 31.

[0028] refer to Figure 3 The dual-mixing nozzle 1 includes a connecting pipe 101. The top of the connecting pipe 101 is connected to a dual-mixing nozzle tube 102. The left side of the dual-mixing nozzle tube 102 is connected to a hose 103. The left side of the hose 103 is connected to a spray head 104. The top of the dual-mixing nozzle tube 102 is connected to the bottom of the connecting pipe 31. The top of the connecting pipe 31 is connected to a dual-mixing nozzle tube 2 105. The left side of the dual-mixing nozzle tube 2 105 is connected to a hose 2 106. The left side of the hose 2 106 is connected to a spray head 2 107.

[0029] As a technical optimization of this utility model, by setting a dual-mixing nozzle 1, liquid can be sprayed out. The user connects to an external infusion tube through a connecting pipe 101. The external infusion tube introduces liquid into the interior of the connecting pipe 101. The connecting pipe 101 introduces liquid into the interior of the dual-mixing nozzle tube 102. The dual-mixing nozzle tube 102 introduces liquid into the interior of the hose 103. The hose 103 introduces liquid into the interior of the spray head 104. The spray head 104 sprays out the liquid. When the hydraulic pressure inside the dual-mixing nozzle tube 102 is too high, the pressure reducing mechanism 3 introduces liquid into the dual-mixing nozzle tube 205. The dual-mixing nozzle tube 205 introduces liquid into the interior of the hose 206. The hose 206 introduces liquid into the interior of the hose 207. The hose 207 sprays out the liquid.

[0030] refer to Figure 2 A vertical plate 21 is fixedly connected to the surface of the spray head distance control mechanism 2. An electric telescopic rod 22 is provided on the right side of the vertical plate 21. The output end of the electric telescopic rod 22 is fixedly connected to the vertical plate 21. Fixing plates 23 are fixedly connected to both sides of the surface of the electric telescopic rod 22. A stabilizing plate 24 is fixedly connected to the inner side of the fixing plate 23. The inner side of the stabilizing plate 24 is fixedly connected to the surface of the first dual-mixing nozzle pipe 102 and the second dual-mixing nozzle pipe 105. A through hole 25 is opened on the right side of the fixing plate 23. The interior of the through hole 25 is fixedly connected to the surface of the first dual-mixing nozzle pipe 102 and the second dual-mixing nozzle pipe 105.

[0031] As a technical optimization of this utility model, by setting a spray head distance control mechanism 2, the first spray head 104 and the second spray head 107 can be driven. The user installs the upright plate 21 on the surface of the first spray head 104 and the second spray head 107, and then installs the fixing plate 23 on the surface of the first dual-mixing nozzle pipe 102 and the second dual-mixing nozzle pipe 105. Then, the electric telescopic rod 22 is driven, and the electric telescopic rod 22 drives the upright plate 21 to move. The position of the first spray head 104 and the second spray head 107 is controlled by the upright plate 21, so that the first spray head 104 and the second spray head 107 are inserted into the interior of the denitrification ammonia spraying equipment.

[0032] refer to Figure 2 A sealing ring 4 is fixedly connected to the inner wall of the plugging ring 32, and the inside of the sealing ring 4 is slidably connected to the surface of the plugging head 33.

[0033] As a technical optimization of this utility model, by setting a sealing ring 4, the gap between the plugging ring 32 and the plugging head 33 can be sealed to prevent liquid from leaking from the gap between the plugging ring 32 and the plugging head 33.

[0034] refer to Figure 2 A slider 5 is fixedly connected to the outer side of the positioning plate 35, and a groove 6 is provided on both sides of the inner wall of the connecting pipe 31. The groove 6 is slidably connected to the slider 5.

[0035] As a technical optimization of this utility model, by setting the slider 5 and the groove 6, the positioning plate 35 can be guided to prevent the positioning plate 35 from shifting when moving.

[0036] refer to Figure 2 The top of the connecting rod 34 is fixedly connected to the limiting plate 7, and the bottom of the limiting plate 7 is in contact with the top of the connecting plate 37.

[0037] As a technical optimization of this utility model, by setting the limiting plate 7, the connecting rod 34 can be guided to prevent the connecting rod 34 from separating from the connecting plate 37.

[0038] The working principle and usage process of this utility model are as follows: During use, the user drives the electric telescopic rod 22, which moves the upright plate 21. The upright plate 21 controls the position of spray head 104 and spray head 107, allowing them to be inserted into the denitrification ammonia spraying equipment. Then, the connecting pipe 101 is connected to an external infusion pipe. The external infusion pipe delivers liquid into the connecting pipe 101, which in turn delivers liquid into the dual-mixing nozzle pipe 102. The dual-mixing nozzle pipe 102 delivers liquid into the flexible hose 103, which then delivers liquid into the spray head 104. 4. When the liquid is sprayed out, and the pressure inside the dual-mixing nozzle tube 102 is too high, the liquid will push open the plug head 33, causing the plug head 33 to separate from the plug ring 32. The plug head 33 drives the connecting rod 34 to move upward, and the connecting rod 34 drives the positioning plate 35 to move upward. The positioning plate 35 and the connecting plate 37 compress the reset spring 36, allowing the liquid to enter the connecting pipe 31. The connecting pipe 31 transmits the liquid into the interior of the dual-mixing nozzle tube 2 105. The dual-mixing nozzle tube 2 105 transmits the liquid into the interior of the hose 2 106. The hose 2 106 transmits the liquid into the interior of the spray head 2 107. The spray head 2 107 sprays out the liquid, reducing the hydraulic pressure inside the dual-mixing nozzle tube 102.

[0039] The dual-mixing nozzle 1 is connected to the external mixing chamber via the connecting pipe 101. An agitator is installed inside the external mixing chamber. The agitator and water pressure are used to fully mix the two liquids, allowing the dual-mixing nozzle 1 to directly spray the mixed liquid. When the water pressure in the external mixing chamber is too high, the two spray heads are used to release the pressure. The released liquid then denitrates the inside of the denitrification ammonia spraying equipment.

[0040] In summary, the dual-mixing nozzle of this denitrification ammonia spraying equipment, by setting a pressure reducing mechanism 3, can transfer the liquid inside the dual-mixing nozzle tube 102 to the dual-mixing nozzle tube 105, thereby reducing the hydraulic pressure inside the dual-mixing nozzle tube 102. When the internal water pressure of the dual-mixing nozzle is too high, the nozzle pipe will not crack or burst. This can reduce the pressure of the dual-mixing nozzle and ensure its service life.
