[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4 As shown, this utility model is a denitrification device for air pollution control, including a treatment box 1, and further comprising: an air inlet pipe 2 fixedly mounted on the side wall of the treatment box 1, an air outlet pipe 3 fixedly mounted at the top center of the treatment box 1, a spray structure provided on the bottom side of the treatment box 1 away from the air inlet pipe 2, an adsorption plate 8 provided in the inner cavity of the treatment box 1, and filter plates 9 distributed above the adsorption plate 8, the adsorption plates 8 being equidistantly distributed on the inner side of the treatment box 1, and the adsorption plates 8 being distributed in a conical shape, a third pipe 10 fixedly connected to one side of the top of the treatment box 1, and a denitrification pump 11 connected to one end of the third pipe 10, the output end of the denitrification pump 11 being connected to a fourth pipe 12, and the fourth pipe 1... The other end of 2 is connected to a denitrification nozzle 13. The denitrification nozzles 13 are equidistantly distributed inside the treatment box 1, and multiple denitrification nozzles 13 are connected to the fourth pipe 12. The bottom of multiple denitrification nozzles 13 is provided with through holes. A filter frame 14 is distributed above the denitrification nozzles 13, and filter holes 15 are provided on the surface of the filter frame 14. The filter holes 15 are equidistantly distributed on one end surface of the filter frame 14, and the diameters of the filter holes 15 on the two ends of the filter frame 14 are different. The diameter of the filter holes 15 on the bottom of the filter frame 14 is larger than that on the upper surface of the filter frame 14. Adsorption balls 16 are provided in the inner cavity of the filter frame 14, and the adsorption balls 16 are equidistantly distributed inside the filter frame 14.

[0024] During operation, flue gas is introduced into the inner side of the treatment chamber 1 through the intake pipe 2. The flue gas then rises and passes through the adsorption plates 8. The multiple adsorption plates 8 achieve preliminary filtration and adsorption treatment of the flue gas. After adsorption treatment, the flue gas passes through the filter plates 9 for further filtration. At the same time, since the denitrification pump 11 is connected to the ammonia tank reserved inside the treatment chamber 1 through the third pipe 10, the denitrification pump 11 draws ammonia into the inner side of the fourth pipe 12 and introduces it into multiple denitrification nozzles 13 through the fourth pipe 12. The ammonia is sprayed out through the holes at the bottom of the denitrification nozzles 13 to achieve denitrification treatment of the flue gas. After denitrification treatment, the air passes through the filter frame 14. The filter holes 15 at the bottom of the filter frame 14, together with the multiple adsorption balls 16 evenly distributed inside, further adsorb and purify the treated air to prevent pollution of the surrounding environment during subsequent emissions.

[0025] The spray structure includes a first pipe 4, a water pump 5, a second pipe 6, and a spray pipe 7. The first pipe 4 is connected to the bottom side of the treatment tank 1, and one end of the first pipe 4 is connected to the water pump 5. The first pipe 4 passes through the side wall of the treatment tank 1 and connects to the inner cavity of the treatment tank 1. The output end of the water pump 5 is connected to the second pipe 6, and the other end of the second pipe 6 is connected to the spray pipe 7. The two ends of the second pipe 6 are respectively connected to the first pipe 4 and the spray pipe 7.

[0026] During operation, the water pump 5 draws the spray water stored at the bottom of the treatment tank 1 into the inside of the second pipe 6 through the first pipe 4. Then, the spray water is input into the inside of the spray pipe 7 through the second pipe 6 and sprayed out through multiple spray nozzles equidistantly opened at the bottom of the spray pipe 7, thereby achieving the spray dust suppression treatment of flue gas.

[0027] A guide plate 17 is fixedly provided on the inner side wall of the top of the processing box 1, and a guide groove 18 is provided on the surface of the guide plate 17. The guide groove 18 is distributed at equal intervals along the inclined surface of the guide plate 17. Arc-shaped grooves 19 are distributed on the inner side of the guide groove 18. The arc-shaped grooves 19 are distributed at equal intervals on the inner side of the guide groove 18, and the arc-shaped grooves 19 and the guide plate 17 form an integrated structure.

[0028] During operation, since the guide plates 17 are symmetrically distributed along both sides of the top of the processing box 1, and multiple guide grooves 18 are equidistantly opened on the inclined surface of the guide plates 17, when air passes through the guide plates 17, the multiple guide grooves 18 equidistantly opened on its surface can be used to divide the air. Then, when the gas flows along the guide grooves 18, since multiple arc-shaped grooves 19 are equidistantly opened at the bottom of the guide grooves 18, and the arc-shaped grooves 19 are generally inwardly arc-shaped, when airflow mixed with particulate matter passes through the arc-shaped grooves 19, a backflow will be formed on the inner side of the arc-shaped grooves 19. Then, under the action of the backflow force, the air continues to flow along the guide grooves 18, while the particulate matter will be left on the inner side of the arc-shaped grooves 19, thereby achieving the removal of particulate matter in the air.

[0029] Inclined plates 20 are distributed at the bottom of the inner cavity of the treatment box 1, and quartz sand plates 21 are distributed below the inclined plates 20. The inclined plates 20 are symmetrically distributed along the vertical center line of the treatment box 1, and the inclined plates 20 and the treatment box 1 are inclined. Bamboo charcoal plates 22 are distributed at the bottom of the quartz sand plates 21.

[0030] During operation, when the spray pipe 7 generates a large amount of wastewater while spraying flue gas, the wastewater will flow along the inclined surface of the inclined plate 20. Then, under the action of the inclined plate 20, the wastewater passes through the quartz sand plate 21, which is used to perform preliminary purification treatment on the wastewater. After treatment, the wastewater will pass through the bamboo charcoal plate 22 for final purification and adsorption treatment, which facilitates the subsequent recycling of the treated wastewater and reduces water consumption.

[0031] The adsorption plates 8 are inclined to the treatment box 1, and the adsorption plates 8 are equidistantly distributed along the inner cavity of the treatment box 1.

[0032] During operation, since the adsorption plates 8 and the treatment box 1 are inclinedly distributed and the multiple adsorption plates 8 form a conical structure, when the flue gas enters the inner side of the treatment box 1 and passes through the adsorption plates 8, the initial filtration and adsorption treatment of the flue gas can be achieved by using the arrangement of multiple adsorption plates 8.

[0033] The flow channels 18 are evenly distributed along the inclined surface of the flow guide plate 17, and the flow channels 18 and the flow guide plate 17 form an integrated structure.

[0034] During operation, since the guide grooves 18 are evenly distributed at the bottom of the guide plate 17, when the air flows along the inclined surface of the guide plate 17, the guide grooves 18 can be used to divide the air, which is convenient for subsequent use with the arc grooves 19 to perform final impurity removal on the treated air.

[0035] Working Principle: Flue gas is introduced into the treatment chamber 1 through the intake pipe 2. At this time, the water pump 5 operates, drawing spray water through the first pipe 4 into the inside of the second pipe 6. The spray water is then introduced into the spray pipes 7 through the second pipe 6 and sprayed out, thus achieving dust suppression treatment of the flue gas. Subsequently, the flue gas rises and passes through the adsorption plates 8. The multiple adsorption plates 8 achieve preliminary filtration and adsorption treatment of the flue gas. After adsorption treatment, the flue gas passes through the filter plates 9 for further filtration. Simultaneously, the denitrification pump 11 operates, drawing ammonia into the inside of the fourth pipe 12. The ammonia is then introduced into multiple denitrification spray pipes 13 through the fourth pipe 12, where it is sprayed out, thus achieving denitrification treatment of the flue gas. The air then... The air passes through the filter frame 14, which, in conjunction with the adsorption balls 16, further adsorbs and purifies the treated air. Finally, the air passes through the guide plate 17, where multiple guide channels 18 divide the air flow. Then, the arc-shaped channel 19 further removes particulate matter mixed in the air. The treated air is then discharged through the exhaust pipe 3. When the spray pipe 7 generates a large amount of wastewater while spraying flue gas, the wastewater flows along the inclined surface of the inclined plate 20. Under the action of the inclined plate 20, the wastewater passes through the quartz sand plate 21, which performs preliminary purification. The treated wastewater then passes through the bamboo charcoal plate 22 for final purification and adsorption, facilitating subsequent recycling of the treated wastewater and reducing water consumption.

[0036] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
