Description

Technical Field

[0001] This utility model relates to the field of flue gas purification technology, specifically to a flue gas purification device for dry desulfurization and denitrification. Background Technology

[0002] Dry flue gas desulfurization technology is a new generation of dry flue gas desulfurization technology creatively developed based on semi-dry desulfurization devices. It draws on the desulfurization principle of semi-dry technology and overcomes the drawbacks of using a slurry preparation system in this technology. Flue gas is a mixture of gas and soot, and is the main cause of air pollution in residential areas. The composition of flue gas is very complex. The gas includes water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons and nitrogen oxides, etc. The soot includes fuel ash, coal particles, oil droplets and high-temperature pyrolysis products, etc.

[0003] Existing flue gas purification devices often neglect the filtration and collection of particulate matter in their design, resulting in purified flue gas still containing a certain amount of particulate matter. This not only affects the purification effect but may also pollute the atmospheric environment. In addition, some devices are difficult to maintain and clean, increasing operating and time costs.

[0004] Therefore, a dry desulfurization and denitrification flue gas purification device is proposed to address the aforementioned problems, such as low purification efficiency, complex equipment maintenance, and the potential for secondary pollution in existing technologies. This device combines desulfurization and denitrification units to achieve effective desulfurization and denitrification of flue gas. Simultaneously, an innovative filter cylinder design efficiently filters and collects particles in the flue gas, ensuring that the purified flue gas meets environmental standards and minimizing its environmental impact. Utility Model Content

[0005] The purpose of this invention is to provide a dry desulfurization and denitrification flue gas purification device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dry desulfurization and denitrification flue gas purification device, comprising:

[0007] The desulfurization device has a denitrification device at its top, and a flue pipe at its top. The surface of the flue pipe is fixed inside the left sealing chamber, and the end of the left sealing chamber is screwed into the right sealing chamber.

[0008] The end of the exhaust pipe is inserted into the filter cylinder, which is rotatably connected to the right sealing chamber. The surface of the right sealing chamber is provided with an exhaust pipe, and the surface of the filter cylinder is provided with exhaust holes.

[0009] Preferably, both the left and right sealing chambers are provided with integrally formed convex rings on their surfaces, and the convex ring surfaces of the left and right sealing chambers are engaged with annular clamps.

[0010] Preferably, a motor is fixedly connected to the surface of the right sealing chamber, the output shaft of the motor is fixed to the surface of the fixed plate, the side surface of the filter screen cylinder is fixedly connected to the surface of the fixed plate, and the surface of the filter screen cylinder is provided with a row of holes, which are round holes. The row of holes are set in multiple groups, and the multiple groups of holes are evenly distributed at equal intervals on the surface of the filter screen cylinder.

[0011] Preferably, the filter cylinder has a cavity groove inside, and a metal ball is movably connected to the surface of the cavity groove. The cavity groove is configured in four groups, and the four groups of cavity grooves are arranged in a circular array along the central axis of the filter cylinder.

[0012] Preferably, the surface of the filter cylinder is provided with an integrally formed stabilizing block, the stabilizing block has a snap-fit ​​groove, the surface of the snap-fit ​​groove is inserted with a plug block, the surface of the plug block is fixedly connected to the bottom surface of the brush plate, and the surface of the brush plate is in close contact with the inner surfaces of the left sealing chamber and the right sealing chamber.

[0013] Preferably, the cross-section of the snap-fit ​​groove is convex, and the depth of the snap-fit ​​groove is equal to the length of the plug block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The desulfurized and denitrified flue gas is discharged into the filter cylinder through the exhaust pipe via the desulfurization and denitrification devices, thereby filtering the particles in the flue gas and purifying it. The particles then pass through the exhaust holes into the left and right sealing chambers, and the purified flue gas is discharged through the exhaust pipe, preventing air pollution. The left and right sealing chambers are detachably connected, allowing for the cleaning of flue gas particles within them. The metal balls are movably connected to the cavity grooves; therefore, when the filter cylinder rotates automatically within the left and right sealing chambers, the metal balls strike the surface of the cavity grooves, causing the filter cylinder to vibrate, thus accelerating the discharge efficiency of the filtered flue gas particles. A brush plate cleans the inner walls of the left and right sealing chambers, preventing flue gas particles from adhering to their inner walls. Attached Figure Description

They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1, please refer to Figures 1-5 This utility model provides a technical solution: a dry desulfurization and denitrification flue gas purification device, comprising:

[0023] The desulfurization device 1 is equipped with a denitrification device 2 at its top and a flue pipe 3 at its top. The surface of the flue pipe 3 is fixed inside the left sealing chamber 4 and the end of the left sealing chamber 4 is screwed into the right sealing chamber 5.

[0024] The end of the exhaust pipe 3 is inserted into the filter cylinder 8, and the filter cylinder 8 is rotatably connected to the right sealing chamber 5. The surface of the right sealing chamber 5 is provided with an exhaust pipe 6, and the surface of the filter cylinder 8 is provided with exhaust holes 9.

[0025] The desulfurized and denitrified flue gas is discharged into the filter cylinder 8 through the exhaust pipe 3 via the desulfurization device 1 and the denitrification device 2. The filter cylinder 8 filters the particles in the flue gas, thus purifying the flue gas. The particles in the flue gas are then discharged into the left sealing chamber 4 and the right sealing chamber 5 through the exhaust hole 9. The purified flue gas is then discharged through the exhaust pipe 6, thus preventing the flue gas from polluting the air. The left sealing chamber 4 and the right sealing chamber 5 are detachably connected, so the flue gas particles in the left sealing chamber 4 and the right sealing chamber 5 can be cleaned.

[0026] Example 2, see attached document Figures 1 to 5Based on Embodiment 1, in order to accelerate the discharge efficiency of flue gas particles filtered by the filter cylinder 8, the left sealing chamber 4 and the right sealing chamber 5 collect the flue gas particles. The surface of the right sealing chamber 5 is fixedly connected to a motor 7, and the output shaft of the motor 7 is fixed to the surface of the fixed plate 15. The surface of the fixed plate 15 is fixedly connected to the side surface of the filter cylinder 8. The surface of the filter cylinder 8 is provided with drainage holes 9. The drainage holes 9 are round holes, and there are multiple sets of drainage holes 9. The multiple sets of drainage holes 9 are evenly distributed at equal intervals on the surface of the filter cylinder 8.

[0027] By starting the motor 7, the fixed plate 15 drives the filter cylinder 8 to rotate automatically in the left sealing chamber 4 and the right sealing chamber 5. As a result, the particles filtered by the filter cylinder 8 are discharged through the discharge hole 9, and the left sealing chamber 4 and the right sealing chamber 5 collect the particles of the flue gas.

[0028] Example 3, refer to Appendix Figures 1 to 5 Based on Embodiment 2, in order to accelerate the filtration and screening efficiency of the material at the top of the filter disc 5, a cavity groove 16 is provided inside the filter cylinder 8. A metal ball 14 is movably connected to the surface of the cavity groove 16. The cavity groove 16 is configured in four groups, and the four groups of cavity grooves 16 are arranged in a ring array along the central axis of the filter cylinder 8.

[0029] By connecting the surface of the metal ball 14 to the cavity groove 16, when the filter cylinder 8 rotates automatically in the left sealing chamber 4 and the right sealing chamber 5, the metal ball 14 strikes the surface of the cavity groove 16, causing the filter cylinder 8 to vibrate, thus accelerating the discharge efficiency of the flue gas particles filtered by the filter cylinder 8.

[0030] Example 4, see attached document Figures 1 to 5 Based on Embodiment 3, in order to prevent flue gas particles from sticking to the inner walls of the left sealing chamber 4 and the right sealing chamber 5, an integrally formed stabilizing block 10 is provided on the surface of the filter cylinder 8. A snap-fit ​​groove 11 is provided in the stabilizing block 10. A snap-fit ​​block 12 is inserted into the surface of the snap-fit ​​groove 11. The bottom surface of the brush plate 13 is fixedly connected to the surface of the snap-fit ​​block 12. The surface of the brush plate 13 is in close contact with the inner surface of the left sealing chamber 4 and the right sealing chamber 5.

[0031] By inserting the surface of the plug block 12 into the surface of the snap-fit ​​groove 11, the brush plate 13 is securely mounted on the surface of the filter cylinder 8, thereby cleaning the particles on the inner walls of the left sealing chamber 4 and the right sealing chamber 5 to prevent flue gas particles from sticking to the inner walls of the left sealing chamber 4 and the right sealing chamber 5.

[0032] In actual use, the desulfurized and denitrified flue gas is discharged into the filter cylinder 8 through the exhaust pipe 3 via the desulfurization device 1 and the denitrification device 2. The filter cylinder 8 filters the particles in the flue gas, thus purifying it. The particles then pass through the exhaust holes 9 into the left sealing chamber 4 and the right sealing chamber 5. The purified flue gas is then discharged through the exhaust pipe 6, preventing air pollution. The left and right sealing chambers 4 and 5 are detachably connected, allowing for the cleaning of flue gas particles within them. Starting the motor 7 causes the fixed disc 15 to automatically rotate the filter cylinder 8 within the left and right sealing chambers 4 and 5, thus allowing the filtered particles to pass through the exhaust holes 9. The exhaust is discharged through hole 9, thereby collecting the flue gas particles in the left sealing chamber 4 and right sealing chamber 5. By movably connecting the surface of the metal ball 14 to the cavity groove 16, when the filter cylinder 8 rotates automatically in the left sealing chamber 4 and right sealing chamber 5, the metal ball 14 strikes the surface of the cavity groove 16, causing the filter cylinder 8 to vibrate, thus accelerating the discharge efficiency of the flue gas particles filtered by the filter cylinder 8. By inserting the surface of the plug block 12 to the surface of the snap-fit ​​groove 11, the brush plate 13 is securely installed on the surface of the filter cylinder 8, thereby cleaning the particles on the inner walls of the left sealing chamber 4 and right sealing chamber 5 to prevent the flue gas particles from sticking to the inner walls of the left sealing chamber 4 and right sealing chamber 5.
