Description

Technical Field

[0001] The invention relates to the technical field of dust removal filter bags, in particular to a denitrification and dust removal device for dust removal filter bags. Background Art

[0002] As the core component of dust removal systems, the performance of dust filter bags is directly related to dust removal efficiency and service life. Traditional dust filter bags primarily focus on capturing dust, but their ability to handle gaseous pollutants in exhaust gas, such as nitrogen oxides, is limited. With tightening environmental regulations, dust removal alone is no longer sufficient to meet current environmental requirements. The integration of dust removal and denitrification technologies has become an inevitable trend.

[0003] Chinese invention patent publication number CN119701498A discloses a denitrification and dust removal device for dust filter bags, comprising a support plate, a support frame mounted with a filter bag, a fixed block at one end of the support frame, and an exhaust pipe connected to the fixed block. A buffer chamber is located above the support plate, and a liquid inlet pipe for introducing ammonia water into the buffer chamber is connected to the buffer chamber below. A connecting pipe is connected above the buffer chamber, and an atomizing nozzle for spraying ammonia water mist outward is provided on the connecting pipe. A regulating mechanism for ammonia water circulation is located above the buffer chamber. The regulating mechanism includes a regulating chamber, and a lifting assembly is provided inside the regulating chamber. The lifting assembly is used to guide the ammonia water in the regulating chamber into the buffer chamber. This denitrification and dust removal device for dust filter bags can denitrify exhaust gas using ammonia water, and the device can operate at an overload, thereby improving the denitrification effect on exhaust gas containing a large amount of nitrogen oxides.

[0004] However, the above patent still has the following shortcomings during actual use: the patent can spray ammonia water toward the inner wall of the filter bag through the atomizing nozzle, and the ammonia water can denitrify the exhaust gas. Although the flow force of the exhaust gas during flow can offset part of the spray force of the atomizing nozzle, it cannot completely offset it, which causes part of the ammonia water to be sprayed onto the inner wall of the filter bag, and the filter bag is prone to become wet. This can easily cause the dust adhering to the outer wall of the filter bag to mix with the ammonia water, which invisibly increases the difficulty of the dust automatically detaching from the outer wall of the filter bag. The dust attached to the filter bag will increase rapidly, and the filtering effect will become worse and worse. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-8 The present invention describes the above technical solution in detail through the following embodiments:

[0031] A denitrification and dust removal device for a dust filter bag comprises a support plate 1 and a fixed block 2, wherein a plurality of support frames 3 arranged at equal angles around the support plate 1 and a plurality of water inlet pipes 4 arranged at equal angles around the support plate 1 are provided between the support plate 1 and the fixed block 2, a filter bag 5 is sleeved on the outer side of all the support frames 3, a plurality of atomizing nozzles 41 arranged at equal intervals along the height direction and a plurality of knocking mechanisms 6 arranged at equal intervals along the height direction and used to knock the support frame 3 are provided on the water inlet pipe 4, the injection port of the atomizing nozzle 41 is away from the inner wall of the filter bag 5, the bottom end of the support plate 1 is provided with a water inlet cavity 11 and a knocking mechanism for sealing A sealing plate 12 closes the water inlet chamber 11, and a driving mechanism 7 is provided in the water inlet chamber 11 for driving all the water inlet pipes 4 to swing synchronously. The bottom of the sealing plate 12 is connected to a delivery pipe 121 for delivering ammonia water, and a transmission mechanism 8 is provided on the delivery pipe 121. The transmission mechanism 8 is connected to the driving mechanism 7 in transmission. A lower guide ring 13 is provided on the top of the support plate 1, and an exhaust pipe 21 is provided on the top of the fixed block 2. An upper guide ring 22 is provided at the bottom of the fixed block 2, and the bottom end of the upper guide ring 22 is located in the lower guide ring 13. An air intake interval is formed between the upper guide ring 22 and the lower guide ring 13.

[0032] The present invention evenly distributes the water inlet pipe 4 for conveying ammonia water between the support plate 1 and the fixed block 2, and makes the nozzle of the atomizing nozzle 41 face the axis of the support plate 1, so that the atomized ammonia water sprayed by the atomizing nozzle 41 will not act on the inner wall of the filter bag 5, and utilizes the conveying force of conveying ammonia water to drive the transmission mechanism 8, and the transmission mechanism 8 transmits the driving force to the driving mechanism 7. The driving mechanism 7 can drive all the water inlet pipes 4 to swing synchronously, and the atomizing nozzle 41 can also swing synchronously, so that the atomized ammonia water can be evenly distributed, and the upper guide ring 22 and the lower guide ring 13 can extend the flow path of the exhaust gas in the filter bag 5, so that the atomized ammonia water can fully contact with the exhaust gas to carry out the denitration reaction, thereby improving the denitration quality.

[0033] When using this device, the ammonia water is pressurized and transported into the delivery pipe 121, and then the ammonia water can enter the water inlet chamber 11 from the delivery pipe 121, and the exhaust gas is also transported simultaneously. The exhaust gas can be filtered through the filter bag 5 and enter the inside of the filter bag 5. The filtered exhaust gas passes through the air intake interval and enters the upper guide ring 22, and is then discharged from the exhaust pipe 21.

[0034] During this process, all the water inlet pipes 4 can be swung synchronously through the cooperation of the transmission mechanism 8 and the driving mechanism 7. The driving mechanism 7 includes an inner ring gear 71, several synchronous gears 72, two support seats 73, a guide slide 74 and a synchronous rack 75. The bottom of the synchronous rack 75 is provided with a guide slider 751 that slides with the guide slide 74. The inner top wall of the water inlet cavity 11 is provided with several first rotating seats 14 that are distributed at equal angles along the circumference of the support disk 1 and rotate with the water inlet pipe 4. The bottom of the fixed block 2 is provided with several The support plate 1 is provided with a second rotating seat 23 that is rotatably matched with the water inlet pipe 4 and is distributed at equal angles around the circumference. The inner gear ring 71 is rotatably set on the inner wall of the water inlet chamber 11. All the synchronous gears 72 are respectively installed on the bottom ends of all the water inlet pipes 4, and all the synchronous gears 72 are engaged with the inner gear ring 71. The two support seats 73 are symmetrically arranged on the top of the sealing plate 12. The guide slide rod 74 is horizontally installed on the two support seats 73. The synchronous rack 75 is engaged with one of the synchronous gears 72, and the transmission mechanism 8 is connected to the synchronous rack 75 in transmission.

[0035] The transmission mechanism 8 includes a third rotating seat 81, a transmission shaft 82, a linkage rod 83 and a convex shell 84. The top of the transmission shaft 82 is provided with a linkage turntable 85, and the top of the linkage turntable 85 is provided with an eccentric column 851. The bottom of the transmission shaft 82 is provided with an impeller 86, and the impeller 86 is provided with a plurality of transmission blades 861 arranged at equal angles around its circumference. The top of one end of the synchronization rack 75 is provided with a hinge column 752. The third rotating seat 81 is set on the sealing plate 12, and the transmission shaft 82 is rotatably set on the third rotating seat 81. The two ends of the linkage rod 83 are respectively hinged on the eccentric column 851 and the hinge column 752. The convex shell 84 is set on the outer wall of the conveying pipe 121, and the impeller 86 is located in the convex shell 84.

[0036] When the delivery pipe 121 delivers ammonia water, the flowing ammonia water can act on the transmission blade 861, and the transmission blade 861 drives the impeller 86 to rotate in the outer convex shell 84. The impeller 86 drives the transmission shaft 82 to rotate synchronously on the third rotating seat 81. The transmission shaft 82 drives the linkage turntable 85 to rotate synchronously. The linkage turntable 85 drives the eccentric column 851 to rotate around its axis. The eccentric column 851 drives one end of the linkage rod 83 to move. The other end of the linkage rod 83 drives the hinged column 752 to move. The hinged column 752 drives The synchronous rack 75 moves back and forth left and right, and the cooperation of the guide slider 751 and the guide slide bar 74 can ensure the movement stability of the synchronous rack 75. The synchronous rack 75 drives the corresponding synchronous gear 72 to swing back and forth clockwise and counterclockwise. The atomizing nozzle 41 changes its effective area during the swinging process. The synchronous gear 72 also drives the inner ring gear 71 to swing synchronously, and the inner ring gear 71 drives the remaining synchronous gears 72 to swing synchronously, so that all the atomizing nozzles 41 can evenly apply the atomized ammonia water to the inside of the filter bag 5.

[0037] Of course, the amount of atomized ammonia water sprayed by the atomizing nozzle 41 is determined by the pressure of the ammonia water delivery, so that the exhaust gas with different nitrogen oxide contents can be denitrified. The water inlet pipe 4 can still swing, but the frequency of the swing is different.

[0038] While the water inlet pipe 4 is swinging, the knocking mechanism 6 can also knock the support frame 3. The knocking mechanism 6 includes a telescopic sleeve 61, a telescopic rod 62 and several abutment blocks 63. A spring 64 is provided in the telescopic sleeve 61, and the head end of the telescopic sleeve 61 is provided with a sliding hole. The tail end of the telescopic rod 62 is provided with a sliding plug 65 that slides with the telescopic sleeve 61. The head end of the telescopic rod 62 is provided with a force block 66. Both the abutment block 63 and the force block 66 are provided with arc surfaces. The telescopic sleeve 61 is horizontally arranged on the outer wall of the water inlet pipe 4, and the telescopic rod 62 is slidably arranged in the sliding hole. The sliding plug 65 contacts the spring 64, and all the abutment blocks 63 are evenly distributed at equal angles on the inner wall of the support frame 3.

[0039] Furthermore, the support frame 3 is an arc-shaped plate.

[0040] When the water inlet pipe 4 swings, it drives all the telescopic sleeves 61 to swing synchronously, the telescopic sleeve 61 drives the telescopic rod 62 to swing synchronously, and the telescopic rod 62 drives the force block 66 to swing synchronously. Since the elastic force of the spring 64 acts on the sliding plug 65, the sliding plug 65 can transmit this force to the telescopic rod 62. The telescopic rod 62 has a force that always extends outward. When the telescopic rod 62 swings, one side of the arc surface of the force block 66 gradually conflicts with one side of the arc surface of the abutment block 63, and then the force block 66 is guided by the abutment and gradually moves toward the telescopic sleeve 61. The telescopic rod 62 moves in the same direction, and the force-bearing block 66 drives the telescopic rod 62 to retract into the telescopic sleeve 61. The telescopic rod 62 drives the sliding plug 65 to move synchronously inward in the telescopic sleeve 61. The sliding plug 65 squeezes the spring 64. After the side of the arc surface is staggered, the elastic force of the spring 64 drives the telescopic rod 62 to extend again. The telescopic rod 62 drives the force-bearing block 66 to immediately hit the arc plate. The arc plate can generate a shaking force, which can be transmitted to the filter bag 5. The dust attached to the outer wall of the filter bag 5 can gradually fall off, thereby realizing automatic cleaning of the dust attached to the outer wall of the filter bag 5.

[0041] Ammonia water enters the water inlet chamber 11 from the delivery pipe 121 and is then diverted from the water inlet chamber 11 to each water inlet pipe 4. A drainage hopper 42 is provided at the bottom of the water inlet pipe 4. The drainage hopper 42 can improve the stability of ammonia water entering the water inlet pipe 4.

[0042] Two baffles 43 are symmetrically arranged on both sides of the atomizing nozzle 41 on the outer wall of the water inlet pipe 4. The baffles 43 can limit and block the effective area of ​​the injection port of the atomizing nozzle 41, thereby preventing the atomized ammonia water from accidentally spreading to the inner wall of the filter bag 5 during injection.

[0043] The lower guide ring 13 is in the shape of a frustum, and the lower half of the upper guide ring 22 is in the shape of an inverted frustum. The exhaust gas flows more smoothly along the oblique side than along the vertical side.
