Description

Technical Field

[0001] This utility model belongs to the field of flue gas denitrification technology, specifically an ammonia injection grid for flue gas denitrification in glass melting furnaces. Background Technology

[0002] Industrial production processes generate waste gas containing nitrogen oxides, requiring denitrification treatment. Selective catalytic reduction (SCR) systems can meet NOx emission standards and are therefore widely used. In SCR systems, the design of the ammonia injection unit affects the mixing effect of ammonia and nitrogen oxides, thus requiring the use of ammonia injection grids. Traditional ammonia injection grids are mostly composed of several nozzles, but this injection method makes it difficult for the flue gas and ammonia emitted from the grid to fully collide and mix, thereby reducing the effectiveness of SCR denitrification. To address this, an ammonia injection grid for denitrification of glass melting furnace flue gas is proposed. Utility Model Content

[0003] Given the following technical problems in the existing technology: traditional ammonia injection grids are mostly composed of several nozzles, but this injection method makes it difficult for the flue gas and ammonia gas ejected from the ammonia injection grid to fully collide and mix, which reduces the effect of SCR denitrification.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example

[0016] Reference Figures 1 to 3This is the first embodiment of the present invention. This embodiment provides an ammonia injection grid for denitrification of flue gas from a glass melting furnace. Specifically, it includes a body 1 and a pretreatment component 2, which includes an air inlet 21, a dispersing component 22, an adjusting component 23, and a collecting component 24. The air inlet 21 is located at the bottom of the body 1, the dispersing component 22 is located at the top of the air inlet 21, the adjusting component 23 is located at the top of the dispersing component 22, and the collecting component 24 is located at the bottom of the dispersing component 22. The filter component 3 includes a reaction platform 31 and an adjusting component 32. The reaction platform 31 is fixedly installed... The regulating component 32 is located inside the reaction platform 31 and is placed on the upper end of the regulating control 23. The user delivers flue gas through the air inlet 21. The flue gas first passes through the dispersing component 22 to disperse the flue gas into two places (to ensure that it can fully contact the ammonia gas later). Then it passes through the regulating control 23, where the flue gas particles are blocked and fall to the collection component 24. The flue gas then enters the reaction platform 31 and passes through the regulating component 32 to slow down the upward flow of the flue gas, so as to ensure that the ammonia gas at the regulating component 32 can fully react with it, thereby achieving the purpose of denitrification.

[0017] Furthermore, the dispersing component 22 includes a fixed frame 221 and a sliding cavity 222. The fixed frame 221 is fixedly installed inside the body 1, and the sliding cavity 222 is slidably installed at the front end of the fixed frame 221. The control panel 23 includes a control plate 231, a coarse hole 232, and a fine hole 233. The control plate 231 is located at the top of the sliding cavity 222, the fine hole 233 is located at the center of the control plate 231, and the coarse hole 232 is located at the edge of the control plate 231. The control plate 231 is shaped like a square cone to facilitate the shedding of particles in the flue gas. The collecting component 24 includes a pull-out groove 241 and a pull-out box 242. The pull-out groove 241 is located at the lower end of the air inlet 21, and the pull-out box 242 is pulled out and installed inside the pull-out groove 241. Smoke gas is discharged into the sliding chamber 222. The sliding chamber 222 can move left and right on the fixed frame 221 to ensure that the smoke gas can reach the coarse hole 232 or the fine hole 233 of the control plate 231. The user can adjust the control in real time according to the size of the smoke particles or the flow speed of the smoke. The blocked smoke particles fall into the pull box 242. The pull box 242 can be pulled out from the pull slot 241 to empty the particles for unified treatment (to prevent accumulation in the pull box 242). At the same time, the control plate 231 is set in a cone shape to allow the particles to roll off during the denitrification reaction at the top of the control plate 231 (the center is a fine hole 233 and the edge is a coarse hole 232 to ensure that the particles roll into the pull box 242 as much as possible). Example

[0018] Reference Figures 1-3As shown, this is the second embodiment of the present invention. This embodiment differs from the previous embodiment in that the adjusting member 32 includes a barbed block 321, a frame 322, and an elastic clamping block 323. The frame 322 is fixedly mounted on the upper end of the control plate 231, and the elastic clamping block 323 is fixedly mounted on the bottom end of the barbed block 321. The elastic clamping block 323 is located at the bottom end of the frame 322 to fix the barbed block 321. Simultaneously, to prevent the reaction between flue gas and ammonia from being too rapid and resulting in insufficient reaction, the barbed block 321 is provided to slow down the flow rate of the flue gas. Multiple barbed blocks 321 are provided to allow the frame 322 to... 22 covers the reaction platform 31. When the flue gas rises to the barbed block 321, it will be blocked by the downward-bent barbs of the barbed block 321 and then rise again, thereby increasing the reaction time with the ammonia gas at the reaction platform 31 to ensure a full reaction. At the same time, in order to regularly clean the flue gas impurities adhering to this block 321, the user can remove this block 321 from the slot of the frame 322 by squeezing the elastic clamp 323 (during installation, simply press the barbed block 321 downward at the slot of the frame 322, at which time the elastic clamp 323 will be opened by the spring for installation).

[0019] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
