Description

Technical Field

[0001] This utility model belongs to the field of gas treatment technology, and in particular relates to a nitrogen sealing gas treatment device. Background Technology

[0002] According to the published patent CN211871460U, a novel ammonia nitrogen scrubbing gas treatment method is described. The reverse spray scrubbing device includes: at least one spray pipe; the inlet of the spray pipe is through which steam to be treated is introduced; multiple first nozzles are arranged vertically inside the spray pipe, with the nozzles facing upwards; the outlet of the spray pipe is connected to the inlet of an acid scrubbing gas tower; the acid scrubbing gas tower is filled with packing material, and multiple second nozzles are arranged above the packing material, with a demister above the second nozzles; the first outlet of the acid scrubbing gas tower is connected to the multiple nozzles via an acid slurry circulation pump, and the second outlet of the acid scrubbing gas tower is connected to a discharge device via an acid slurry discharge pump. This invention, with its two-stage scrubbing, ensures that the ammonia in the steam reacts fully with the acid, minimizing the ammonia nitrogen content in the steam condensate. However, it still has the following shortcomings: After completion, the above equipment simply processes the gas by spraying condensate. However, since the condensate needs time to react with the impurities inside the gas, if there are too many impurities in the gas, the required reaction time will also increase, which will lead to a decrease in the processing efficiency of the device.

Through a filtration mechanism and an auxiliary mechanism, it solves the problem that the reaction time required between condensate and impurities inside the gas is relatively long, and the reaction time will increase if there are too many impurities in the gas, thus reducing the processing efficiency of the device.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a nitrogen sealing gas treatment device, including a base plate, and a sealing tank is fixedly connected to the top outer wall of the base plate; The outer wall of the sealed container is provided with a filtration mechanism, which includes an air pump. The outer wall of the air pump is fixedly connected to the outer wall of the sealed container. An exhaust pipe is fixedly connected to the output end of the air pump. A filter cylinder is rotatably connected to the inner wall of the exhaust pipe. A rack is fixedly connected to the outer wall of the filter cylinder. A fan is rotatably connected to the inner wall of the exhaust pipe near the air pump. A positioning shaft is fixedly connected to the outer wall of the fan. A first gear is fixedly connected to the outer wall of the positioning shaft away from the fan. Several second gears mesh with the outer wall of the first gear. A connecting rod is fixedly connected to the outer wall of the several second gears. Several connecting blocks are fixedly connected to the outer wall of the connecting rod. A positioning ring is fixedly connected to the outer wall of the connecting block. An arc-shaped scraper is fixedly connected to the outer wall of the connecting rod.

[0005] Furthermore, the outer wall of the positioning ring is slidably connected to the inner wall of the exhaust pipe, the outer wall of the arc-shaped scraper is slidably connected to the inner wall of the filter cylinder, the outer wall of the second gear meshes with the outer wall of the rack, and the outer wall of the exhaust pipe is provided with an auxiliary mechanism.

[0006] Furthermore, the auxiliary mechanism includes a processing box, the outer wall of which is fixedly connected to the outer wall of the exhaust pipe, a motor is fixedly connected to the inner wall of the processing box, the output end of the motor is fixedly connected to a connecting shaft via a coupling, a first positioning plate is fixedly connected to the outer wall of the connecting shaft, a fixing rod is fixedly connected to the outer wall of the first positioning plate, and a second positioning plate is fixedly connected to the outer wall of the end of the fixing rod away from the first positioning plate.

[0007] Furthermore, the outer wall of the fixed rod is rotatably connected to several support rods, and the outer wall of one end of the several support rods away from the second positioning plate is rotatably connected to a connecting rod. The outer wall of the other end of the connecting rod is rotatably connected to a scraper, and the outer wall of the scraper is slidably connected to the outer wall of the filter plate.

[0008] Furthermore, the outer wall of the filter plate is fixedly connected to the inner wall of the processing box, a limit plate is fixedly connected to the inner wall of the processing box, and a damper is fixedly connected to the inner wall of the limit plate.

[0009] Furthermore, a limit block is fixedly connected to the outer wall of the end of the damper away from the limit plate, the outer wall of the limit block is rotatably connected to the outer wall of the connecting rod, and a spring is fixedly connected to the outer wall of the damper.

[0010] Furthermore, a condensate tank is fixedly connected to the top outer wall of the base plate, the outer wall of the condensate tank is fixedly connected to the outer wall of the treatment tank, and a water pump is fixedly connected to the top outer wall of the condensate tank.

[0011] Furthermore, the output end of the water pump is fixedly connected to a water outlet pipe, and a nozzle is fixedly connected to the outer wall of the water outlet pipe. The outer wall of the nozzle is fixedly connected to the inner wall of the treatment tank, and both the inner walls of the treatment tank and the condensate tank are provided with drain outlets.

[0012] This utility model has the following beneficial effects: 1. This utility model incorporates a filter cylinder and a rack. The centrifugal force generated by the fan's rotation draws the gas closer to the filter cylinder. The rotation of the second gear drives the rack to rotate in the opposite direction, simultaneously causing the filter cylinder to slide inside the exhaust pipe. The shearing force generated by the reverse rotation of the filter cylinder breaks up the airflow, thereby increasing the contact area between the filter cylinder and the gas. This design utilizes the reverse rotation of the filter cylinder to increase the contact area between the gas and the filter cylinder, preventing the problem that the reaction time between condensate and impurities in the gas needs to be increased. If there are too many impurities in the gas, the required reaction time will also increase, leading to a decrease in the processing efficiency of the device.

[0013] 2. This utility model incorporates a filter plate and a scraper. Since both ends of the fixing rod are located on the outermost sides of both the first and second positioning plates, and their connection positions are consistent, when the fixing rod is away from the axis of the first and second positioning plates, its rotation pushes the support rod to move, simultaneously moving the connecting rod. This causes the connecting rod to push the scraper, making it slide along the surface of the filter plate. This achieves the goal of filtering impurities from the liquid through the filter plate while simultaneously cleaning the surface of the filter plate using the movement of the scraper, increasing the filter plate's lifespan. It also prevents impurities from remaining inside the liquid after the reaction of condensate and gas, which could alter the liquid's composition, making it unusable and increasing the device's operating costs.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 As shown, this utility model is a nitrogen sealing gas treatment device, including a base plate 1, and a sealing tank 101 is fixedly connected to the top outer wall of the base plate 1. The sealing tank 101 reduces the possibility of leakage during gas sealing. A filter mechanism 2 is provided on the outer wall of the sealed container 101. The filter mechanism 2 includes an air pump 201, the outer wall of which is fixedly connected to the outer wall of the sealed container 101. The air pump 201 replaces the gas in the sealed container 101 and the processing box 301. An exhaust pipe 202 is fixedly connected to the output end of the air pump 201. A filter cylinder 203 is rotatably connected to the inner wall of the exhaust pipe 202. The filter cylinder 203 filters the gas in the exhaust pipe 202. A rack 204 is fixedly connected to the outer wall of the filter cylinder 203. The exhaust pipe 202 is close to the air pump. A fan 205 is rotatably connected to the inner wall of one end of the filter cartridge 201. The centrifugal force generated by the rotation of the fan 205 moves the gas blown outwards by the air pump 201, increasing the contact area and time between the filter cartridge 203 and the gas. A positioning shaft 206 is fixedly connected to the outer wall of the fan 205. A first gear 207 is fixedly connected to the outer wall of the end of the positioning shaft 206 furthest from the fan 205. Several second gears 208 mesh with the outer wall of the first gear 207. A connecting rod 209 is fixedly connected to the outer wall of the several second gears 208. As discussed, the first gear 207 meshes with the second gear 208, thereby rotating the first gear 207 to drive the second gear 208 to rotate, which in turn moves the connecting rod 209. Several connecting blocks 211 are fixedly connected to the outer wall of the connecting rod 209, and positioning rings 212 are fixedly connected to the outer wall of each connecting block 211. The positioning rings 212 move along the inner wall of the exhaust pipe 202, thus stabilizing the movement range of the connecting rod 209. An arc-shaped scraper 210 is fixedly connected to the outer wall of the connecting rod 209. The movement of the connecting rod 209 is controlled by the scraper. The arc-shaped scraper 210 is driven to clean along the inner wall of the filter cylinder 203. The outer wall of the positioning ring 212 is slidably connected to the inner wall of the exhaust pipe 202. The outer wall of the arc-shaped scraper 210 is slidably connected to the inner wall of the filter cylinder 203. The outer wall of the second gear 208 meshes with the outer wall of the rack 204. Through the meshing of the second gear 208 and the rack 204, the rotation of the second gear 208 drives the rack 204 to rotate, while driving the fan 205 of the filter cylinder 203 to rotate in the opposite direction. An auxiliary mechanism 3 is provided on the outer wall of the exhaust pipe 202.

[0020] Auxiliary mechanism 3 includes a processing box 301. The outer wall of the processing box 301 is fixedly connected to the outer wall of the exhaust pipe 202. A motor 302 is fixedly connected to the inner wall of the processing box 301. The motor 302 is started. The output end of the motor 302 is fixedly connected to a connecting shaft 303 via a coupling. A first positioning plate 304 is fixedly connected to the outer wall of the connecting shaft 303. A fixing rod 305 is fixedly connected to the outer wall of the first positioning plate 304. A second positioning plate 305 is fixedly connected to the outer wall of the end of the fixing rod 305 away from the first positioning plate 304. 6. The fixing rod 305 simultaneously connects the first positioning plate 304 and the second positioning plate 306, thereby causing the first positioning plate 304 and the fixing rod 305 to rotate simultaneously. Several support rods 307 are rotatably connected to the outer wall of the fixing rod 305. A connecting rod 308 is rotatably connected to the outer wall of one end of each support rod 307 away from the second positioning plate 306. Since the second positioning plate 306 is located at the outermost edge of the first positioning plate 304 and the fixing rod 305, the rotation of the fixing rod 305 will push the support rods 307 to move. Simultaneously, the linkage 308 moves, and a scraper 309 is rotatably connected to the outer wall of the other end of the linkage 308. The outer wall of the scraper 309 is slidably connected to the outer wall of the filter plate 310. The linkage 308 pushes the scraper 309 to move on the surface of the filter plate 310, thereby cleaning the surface of the filter plate 310. The outer wall of the filter plate 310 is fixedly connected to the inner wall of the processing box 301. A limit plate 312 is fixedly connected to the inner wall of the processing box 301, and a damper 313 is fixedly connected to the inner wall of the limit plate 312. The movement of the connecting rod 308 causes the limiting block 311 to move while simultaneously squeezing the damper 313 and relieving the pressure on the limiting block 311 during its movement. The outer wall of the end of the damper 313 away from the limiting plate 312 is fixedly connected to the limiting block 311. The outer wall of the limiting block 311 is rotatably connected to the outer wall of the connecting rod 308. A spring 314 is fixedly connected to the outer wall of the damper 313. The damper 313 is configured to automatically compress the spring 314 when it is squeezed, thereby increasing the relieving force of the damper 313 on the limiting block 311.

[0021] A condensate tank 315 is fixedly connected to the top outer wall of the base plate 1. The outer wall of the condensate tank 315 is fixedly connected to the outer wall of the treatment tank 301. A water pump 316 is fixedly connected to the top outer wall of the condensate tank 315. When the water pump is started, a water outlet pipe 317 is fixedly connected to the output end of the water pump 316. A nozzle 318 is fixedly connected to the outer wall of the water outlet pipe 317. The outer wall of the nozzle 318 is fixedly connected to the inner wall of the treatment tank 301. By placing the nozzle 318 on the top of the treatment tank 301, it is ensured that the liquid sprayed by the nozzle 318 can cover the interior of the treatment tank 301. Both the inner walls of the treatment tank 301 and the condensate tank 315 are provided with drain outlets 319, which facilitate the return of the treated liquid in the treatment tank 301 to the condensate tank 315.

[0022] One specific application of this embodiment is: When the equipment is needed, the air pump 201 is started to draw gas from the sealed tank 101 into the exhaust pipe 202. The flow of gas in the exhaust pipe 202 drives the fan 205 to rotate, which in turn drives the positioning shaft 206 to rotate. The positioning shaft 206 drives the first gear 207 to rotate. Since the first gear 207 meshes with multiple second gears 208, the rotation of the first gear 207 can drive the multiple second gears 208 to rotate, while simultaneously driving the connecting rod 209 to rotate. Furthermore, since the second gears 208 mesh with the rack 204, the rotation of the second gears 208 can drive the rack 204 to rotate in the opposite direction, while simultaneously driving the filter cartridge 203 to rotate in the exhaust pipe 202. The filter cylinder 202 slides inside the filter 202. The shearing force generated by the reverse rotation of the filter cylinder 203 breaks up the airflow, increasing the contact area between the filter cylinder 203 and the gas. Since the position of the connecting rod 209 is not fixed, as the first gear 207 drives the second gear 208 to rotate, the second gear 208 drives the connecting rod 209 to move. The connecting rod 209 moves the connecting block 211, simultaneously causing the positioning ring 212 to rotate and fit against the inside of the exhaust pipe 202, thus limiting the range of movement of the connecting rod 209. The movement of the connecting rod 209 drives the arc-shaped scraper 210 to move against the surface of the filter cylinder 203, thereby cleaning the surface of the filter cylinder 203. The treated gas then enters the treatment tank 301. The water pump 316 at the rear of the treatment tank 301 is activated, drawing liquid from the condensate tank 315 and simultaneously sending it through the outlet pipe 317 into the nozzle 318. The nozzle 318 sprays the liquid onto the inside of the treatment tank 301. The sprayed condensate lowers the gas temperature and causes water vapor in the gas to condense into droplets that fall onto the surface of the filter plate 310 at the bottom of the treatment tank 301. During the condensation process, impurities inside the gas are carried away by the water vapor, which are then filtered out by the filter plate 310. The filtered water droplets flow back into the condensate tank 315 through the drain outlet 319. While the filter plate 310 is filtering the liquid, the motor 302 can be activated to drive the connecting shaft 303. While rotating, the first positioning plate 304 is driven to rotate, and the second positioning plate 306 at the other end is connected by a fixing rod 305. Thus, when the first positioning plate 304 rotates, the fixing rod 305 drives the second positioning plate 306 at the other end to rotate. Since both ends of the fixing rod 305 are located on the outermost sides of both the first positioning plate 304 and the second positioning plate 306, and their connection positions are consistent, when the fixing rod 305 moves away from the axis of the first positioning plate 304 and the second positioning plate 306, the rotation of the fixing rod 305 will push the support rod 307 to move, thereby driving the connecting rod 308 to move. The connecting rod 308 will then push the scraper 309 to slide along the surface of the filter plate 310.During the movement of the connecting rod 308, it drives the limiting block 311 to move along the interior of the limiting plate 312. Simultaneously, the limiting block 311 compresses the damper 313 inside the limiting plate 312, thereby relieving the pressure generated during the movement of the limiting block 311. Furthermore, the damper 313 is pre-set to automatically compress the outer spring 314 when compressed, thus increasing the damping effect of the damper 313.
