Description
Technical Field
[0001] This invention belongs to the field of denitrification technology, specifically relating to a honeycomb catalyst high-efficiency denitrification device. Background Technology
[0002] With the rapid development of industrial sectors, nitrogen oxides (NOx) produced during fossil fuel combustion, chemical production, and other processes have become increasingly prevalent. x Nitrogen oxide emissions continue to increase, becoming one of the main pollutants causing environmental problems such as acid rain and photochemical smog, seriously threatening the ecological environment and human health. As the core means of controlling nitrogen oxide emissions, the efficiency and stability of its technical equipment have attracted much attention. Honeycomb catalysts are widely used in industrial denitrification devices due to their advantages such as large specific surface area, high catalytic activity and strong pressure resistance.
[0003] However, existing honeycomb catalyst denitrification devices still have many technical pain points in practical applications. The denitrification structure is mostly a fixed design, and the contact area between the catalyst and the flue gas cannot be dynamically adjusted according to the concentration of nitrogen oxides in the flue gas. When the concentration of pollutants in the flue gas fluctuates greatly, the denitrification is prone to incomplete or low denitrification efficiency, making it difficult to balance treatment effect and treatment rate.
[0004] Therefore, developing a highly efficient denitrification device capable of dynamically adjusting the catalytic structure has become an urgent need in the field of industrial denitrification technology. Summary of the Invention
[0005] The purpose of this invention is to provide a honeycomb catalyst high-efficiency denitrification device that can flexibly adapt the contact area between the catalyst and the flue gas. When the concentration of nitrogen oxides is high, the contact area is expanded to ensure the thoroughness of denitrification, and when the concentration is low, the contact area is reduced to increase the processing rate. At the same time, the adjustable structure can flexibly adjust the tilt angle of the mounting plate to optimize the flue gas flow path and enhance the catalytic reaction effect.

[0010] The adjustment structure includes a rotating column installed at the end of the mounting plate. The rotating column is rotatably connected to the inner wall of the denitrification tower. A swing plate is fixed to the side of the rotating column away from the denitrification tower. Slide grooves are provided on the inner walls of both sides of the swing plate. Sliding blocks are slidably connected in the slide grooves. Rotating shafts are rotatably connected to the sides of the two sliding blocks that are close to each other. Moving blocks are fixed to the sides of the two rotating shafts that are close to each other. Screws are threadedly connected to multiple moving blocks on the same side of the denitrification tower. Multiple screws on the same side of the denitrification tower are fixedly connected. A first motor is installed on the outside of the denitrification tower.

[0012] The airbag contains a first air chamber, and a second air chamber is provided on both sides of the first air chamber, and the first air chamber and the second air chamber are interconnected.
[0013] An inclined plate is fixed between every two adjacent mounting plates. An installation groove is provided on the inclined plate near the position corresponding to the electric push rod and the honeycomb catalytic brick. An upper blocking plate is fixed at the end of the installation groove away from the inclined plate. Both the inclined plate and the upper blocking plate are close to the upper honeycomb catalytic plate and the honeycomb catalytic brick.
[0014] A guide plate is fixed to the top of the mounting plate near the honeycomb catalytic brick, and the guide plate is connected to the inclined plate.
[0015] The inclined plate is inclined downward toward the end away from the mounting groove. An electromagnet is installed inside the inclined plate.

The overall structure achieves a dynamic balance between denitrification effect and rate, solving the problem of traditional fixed structures being unable to adapt to flue gas concentration fluctuations, and significantly improving the adaptability and efficiency of the denitrification device.

[0022] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.
[0023] like Figures 1-9 As shown, a honeycomb catalyst high-efficiency denitrification device includes a denitrification tower 1, a honeycomb catalyst 2 is installed inside the denitrification tower 1 near the bottom, a first detector 11 is installed inside the denitrification tower 1 and on top of the honeycomb catalyst 2, and multiple mounting plates 3 are installed inside the denitrification tower 1 and on top of the honeycomb catalyst 2, with the multiple mounting plates 3 installed at height intervals on one side and the other side of the inner wall of the denitrification tower 1, a honeycomb catalyst plate 4 is provided on one side of the bottom of the mounting plate 3, and a denitrification enhancement structure is installed on the other side of the bottom of the mounting plate 3;
[0024] The flue gas enters the denitrification tower 1 from the bottom and passes through the honeycomb catalyst 2 for the first denitrification, which removes nitrogen oxides such as nitric oxide (NO) and nitrogen dioxide (NO2) from the flue gas. Then, the flue gas passes through the honeycomb catalyst 2 and reaches the mounting plate 3, where it comes into contact with the honeycomb catalyst 4. The flue gas then undergoes a second denitrification process through the honeycomb catalyst 4. After passing through the enhanced denitrification structure, the flue gas reaches the top of the mounting plate 3 and comes into contact with the honeycomb catalyst 4 and the enhanced denitrification structure above it for further denitrification, thereby increasing the denitrification effect.
[0025] The denitrification structure is enhanced for further denitrification treatment.
[0026] See attached document Figure 4The enhanced denitrification structure includes multiple honeycomb catalytic bricks 6, all of which are slidably connected to the other side of the bottom of the mounting plate 3. Each pair of adjacent honeycomb catalytic bricks 6 is rotatably connected. An electric push rod 7 is installed at the bottom of the mounting plate 3. A fixing plate 9 is fixed vertically downwards on the stroke rod of the electric push rod 7. The fixing plate 9 is connected to one of the bottom honeycomb catalytic bricks 6. The flue gas passes through the honeycomb catalytic plate 4, causing it to denitrify. The bottom of one side of the mounting plate 3, i.e., the side of the honeycomb catalytic plate 4, is lower than the bottom of the other side, i.e., the side of the honeycomb catalytic brick 6. An inclined surface 5 is provided between the bottom of the mounting plate 3 and the other side. This inclined surface 5 allows the rising flue gas to automatically drift to the location of the honeycomb catalytic brick 6. When the first detector 11 detects a high nitrogen oxide content in the flue gas, it can drive the electric push rod 7, causing the stroke rod of the electric push rod 7 to move the fixing plate 9 upwards. This causes the bottom honeycomb catalytic brick 6 to move upwards. Each honeycomb catalytic brick 6 is slidably connected to the bottom of the mounting plate 3, and every two adjacent honeycomb catalytic bricks 6 are rotatably connected. As the honeycomb catalytic bricks 6 move upwards, they can automatically spread out at the bottom of the mounting plate 3, so that each honeycomb catalytic brick 6 can contact the flue gas as much as possible, thereby removing nitrogen oxides in the flue gas and ensuring the denitrification effect. If the first detector 11 detects that the nitrogen oxide content in the flue gas is low, it can drive the electric push rod 7, so that the stroke rod of the electric push rod 7 drives the fixed plate 9 and the bottom honeycomb catalytic brick 6 to move downwards, thereby reducing the number of honeycomb catalytic bricks 6 spread at the bottom of the mounting plate 3. This allows the flue gas to quickly pass through the honeycomb catalytic bricks 6 and move to the top of the mounting plate 3, thereby increasing the denitrification rate while ensuring the denitrification effect of the flue gas. The honeycomb catalyst 2, honeycomb catalytic plate 4, and honeycomb catalytic brick 6 are actually made of the same material.
[0027] An adjustment structure is installed on the outside of the denitrification tower 1 to adjust the height of multiple mounting plates 3.
[0028] See attached document Figure 2 , 3 4 and Figure 5The adjustment structure includes a rotating column 19 installed at the end of the mounting plate 3. The rotating column 19 is rotatably connected to the inner wall of the denitrification tower 1. A swing plate 20 is fixed on the side of the rotating column 19 away from the denitrification tower 1. Slide grooves 21 are provided on the inner walls of both sides of the swing plate 20. Sliding blocks 24 are slidably connected in the slide grooves 21. Rotating shafts 23 are rotatably connected on the side of the two sliding blocks 24 that are close to each other. Moving blocks 22 are fixed on the side of the two rotating shafts 23 that are close to each other. Screws 25 are threadedly connected in the multiple moving blocks 22 on the same side of the denitrification tower 1. Multiple screws 25 on the same side of the denitrification tower 1 are fixedly connected. A first motor 26 is installed on the outside of the denitrification tower 1. The output end of the first motor 26 is fixedly connected to one of the screws 25.
[0029] When it is necessary to change the tilt angle of the mounting plate 3, the honeycomb catalytic plate 4, and the honeycomb catalytic brick 6, the first motor 26 can be started, causing the output end of the first motor 26 to rotate and drive the screw 25 to rotate. When the screw 25 rotates, through the threaded connection between the screw 25 and the moving block 22, and through the moving block 22 set inside the swing plate 20, the moving block 22 can drive the swing plate 20 to move downward, and through the lever principle, the end of the mounting plate 3 away from the rotating column 19 swings upward, thereby allowing the flue gas to move upward along the mounting plate 3. Thus, when the first detector 11 detects that the nitrogen oxides in the flue gas are low, the denitrification rate can be increased while ensuring the denitrification effect of the flue gas.
[0030] See attached document Figures 6-7 A first sealing gasket 27 is provided on the outer side of the rotating column 19. Multiple second sealing gaskets 28 are installed on the outer side of the first sealing gasket 27, with a gap 29 between every two adjacent second sealing gaskets 28. Each second sealing gasket 28 contains an air bladder 30. The first sealing gasket 27 enhances the sealing effect between the rotating column 19 and the denitrification tower 1. When the rotating column 19 rotates to the point where its contact with the denitrification tower 1 is at the gap 29, the two second sealing gaskets 28 can increase the sealing effect between the rotating column 19 and the denitrification tower 1. To ensure the sealing of the contact point between the tower 1 and the denitrification tower 1, a first air chamber 31 is provided inside the airbag 30, and a second air chamber 32 is provided on both sides of the first air chamber 31 inside the airbag 30. The first air chamber 31 and the second air chamber 32 are interconnected. When the rotating column 19 rotates to the point where the contact point between it and the denitrification tower 1 is exactly on the second sealing gasket 28, the gas in the first air chamber 31 can be squeezed into the second air chamber 32 by squeezing the second sealing gasket 28, which increases the degree of expansion on both sides of the second sealing gasket 28. This can also increase the sealing of the contact point between the rotating column 19 and the denitrification tower 1, thereby preventing the leakage of flue gas inside the denitrification tower 1.
[0031] See attached document Figures 3-4An inclined plate 10 is fixed between every two adjacent mounting plates 3. An installation groove 13 is provided at the position of the inclined plate 10 near the electric push rod 7 and the honeycomb catalytic brick 6. An upper baffle plate 12 is fixed at the end of the installation groove 13 away from the inclined plate 10. Both the inclined plate 10 and the upper baffle plate 12 are close to the upper honeycomb catalytic plate 4 and honeycomb catalytic brick 6.
[0032] After the flue gas is denitrified by the honeycomb catalytic plate 4 and the honeycomb catalytic brick 6, the flue gas moves to the top of the mounting plate 3 and extends to the top of the inclined plate 10, thereby allowing the flue gas to contact the honeycomb catalytic plate 4 and reducing the area of the flue gas moving from the bottom of the honeycomb catalytic plate 4, thus making the contact between the flue gas and the honeycomb catalytic plate 4 better. Similarly, the upper baffle plate 12 can limit the area of the flue gas moving from the bottom of the honeycomb catalytic brick 6, thereby ensuring the contact effect between the flue gas and the honeycomb catalytic brick 6, and further increasing the denitrification effect of the flue gas. The width of the upper baffle plate 12 is much larger than the width of components such as the electric push rod 7 and the fixed plate 9, so that when the electric push rod 7 and the fixed plate 9 swing with the mounting plate 3, the mounting groove 13 avoids restricting the angle change of the electric push rod 7.
[0033] A guide plate 14 is fixed to the top of the mounting plate 3 near the honeycomb catalytic brick 6, and the guide plate 14 is connected to the inclined plate 10. The guide plate 14 can prevent the flue gas from moving from the bottom of the inclined plate 10. The guide plate 14 is made of a flexible material, such as rubber or silicone, so that when the mounting plate 3 swings, the guide plate 14 can deform, thus always blocking the flue gas from passing between the mounting plate 3 and the inclined plate 10.
[0034] See attached document Figure 4 The inclined plate 10 is inclined downward toward the end away from the mounting groove 13. An electromagnet 15 is installed inside the inclined plate 10. An elastic rod 16 is installed on the top of the inclined plate 10. The top of the elastic rod 16 extends to the top of the electromagnet 15 and a magnet ball 17 is fixed thereon. A collection bin 18 is fixed on the inner wall of the denitrification tower 1 and located diagonally below the inclined plate 10.
[0035] When the electromagnet 15 is activated, it attracts the magnetic ball 17, causing the magnetic ball 17 to move towards the electromagnet 15. When the electromagnet 15 is de-energized, it stops attracting the magnetic ball 17. The elastic rod 16, through its elastic setting, drives the magnetic ball 17 to move upward. This elastic setting causes the magnetic ball 17 to move upward rapidly. When the electromagnet 15 starts and stops rapidly, the magnetic ball 17 can strike the honeycomb catalytic plate 4 at the top, causing the honeycomb catalytic plate 4 to vibrate and shake off the small dust particles inside. When the elastic rod 16 swings back and forth, it can also vibrate the inclined plate 10, guiding the small dust particles on the inclined plate 10 and those falling from the honeycomb catalytic plate 4 into the collection chamber 18 through the inclined setting of the inclined plate 10. The collection chamber 18 then collects the dust, which can then be collected periodically by the user.
[0036] See attached document Figures 8-9 A second detector 34 is fixed to the inner wall of the denitrification tower 1 and on top of multiple mounting plates 3. This second detector 34, like the aforementioned first detector 11, can detect the denitrification effect. It can be used for chemiluminescence NO detection. x Analyzer, Non-dispersive infrared / ultraviolet analyzer, Electrochemical NO x The denitrification tower 1 includes instruments such as sensors and laser Raman spectrometers. A baffle plate 37 is fixed inside the tower and at the top of the second detector 34. A rotating plate 38 is rotatably connected inside the baffle plate 37. A second motor 8 is installed on the outside of the denitrification tower 1, and its output is connected to the rotating plate 38. At least one adsorption tube 33 is installed on the outside of the denitrification tower 1, with its top and bottom extending into the tower. The top of the adsorption tube 33 extends to a position close to the second detector 34. A solenoid valve 35 is installed inside the adsorption tube 33, and a fan 36 is installed inside the adsorption tube 33 at the bottom of the solenoid valve 35. The bottom of the adsorption tube 33 extends to a position close to the bottom of the honeycomb catalyst 2. The second detector 34 detects the flue gas at the top of the mounting plate 3. When the test is qualified, the second motor 8 is started, so that the output end of the second motor 8 drives the rotating plate 38 to rotate, and then the flue gas moves through the rotating plate 38 and the baffle plate 37 to the top of the denitrification tower 1 and is discharged from the denitrification tower 1. When the second detector 34 detects that the nitrogen oxides in the flue gas are unqualified, the second motor 8 closes the rotating plate 38, so that the flue gas stays at the bottom of the baffle plate 37, and the solenoid valve 35 is opened, so that the flue gas can enter the adsorption tube 33. The fan 36 is started, so that the fan 36 can draw the flue gas and reintroduce it to the bottom of the honeycomb catalyst 2 for a new round of denitrification treatment.
[0037] The denitrification tower 1 is equipped with at least one control chip, which is electrically connected to the first detector 11 and the second detector 34, and also electrically connected to the fan 36, the solenoid valve 35, the first motor 26 and the electric push rod 7. The first detector 11 and the second detector 34 transmit signals to the control chip, and the control chip controls the fan 36 and the solenoid valve 35, the first motor 26 and the electric push rod 7 and the second motor 8 to start and stop.
[0038] The working principle of this application is as follows:
[0039] Flue gas enters from the bottom of denitrification tower 1 and first flows through honeycomb catalyst 2 to complete the first denitrification, initially removing nitrogen oxides;
[0040] The first detector 11 monitors the concentration of nitrogen oxides in the flue gas in real time. If the concentration is too high, the electric push rod 7 drives the fixed plate 9 to move upward, causing multiple rotating honeycomb catalytic bricks 6 to spread at the bottom of the mounting plate 3. This, together with the honeycomb catalytic plate 4, expands the catalytic contact area. The inclined surface 5 at the bottom of the mounting plate 3 guides the flue gas to flow automatically to the catalytic structure, ensuring thorough denitrification. If the concentration is too low, the electric push rod 7 causes the honeycomb catalytic bricks 6 to contract, reducing contact resistance and increasing the denitrification rate.
[0041] The first motor 26 drives the screw 25 to rotate, which in turn drives the moving block 22 and the slider 24 to slide along the groove 21 of the swing plate 20. The tilt angle of the mounting plate 3 is adjusted by the rotating column 19. The inclined plate 10, the upper blocking plate 12 and the guide inclined plate 14 between adjacent mounting plates 3 prevent the flue gas from short-circuiting and force the flue gas to fully contact the honeycomb catalytic plate 4 and the honeycomb catalytic brick 6 to enhance the catalytic effect.
[0042] Electromagnet 15 starts and stops intermittently, attracting or releasing magnetic ball 17. Combined with the elastic action of elastic rod 16, magnetic ball 17 repeatedly strikes honeycomb catalyst plate 4, shaking off surface dust. Inclined plate 10 is set at an angle, and the dust slides down to collection chamber 18 with vibration, reducing catalyst blockage.
[0043] The first sealing gasket 27, multiple sets of second sealing gaskets 28 and airbag 30 on the outer side of the rotating column 19 work together to seal. When the rotating column 19 rotates, the airbag 30 expands by gas compression to fill the gap 29 and prevent smoke leakage.
[0044] The second detector 34 detects the flue gas after multi-layer catalytic treatment. If it meets the standard, the second motor 8 drives the rotating plate 38 to open, and the flue gas is discharged through the baffle plate 37. If it does not meet the standard, the rotating plate 38 closes, the solenoid valve 35 and the fan 36 start, and the flue gas is returned to the bottom of the honeycomb catalyst 2 through the adsorption tube 33 for secondary denitrification, thus achieving closed-loop treatment.
[0045] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
