Description

Technical Field

[0001] The invention relates to the technical field of pyrolysis furnace flue gas purification, in particular to a waste article recycling pyrolysis furnace flue gas purification system for preventing and controlling solid waste pollution. Background Art

[0002] Solid waste refers to solid, semi-solid and gaseous items in containers that have lost their original utility value or have not lost their utility value but have been discarded or abandoned during production, life and other activities; a pyrolysis furnace is a reaction device that decomposes solid matter into gaseous, liquid and solid substances through thermochemical conversion methods. Its core is to use high temperature to crack the material; the fuel layer in the pyrolysis furnace can usually be divided into a drying layer, a pyrolysis layer and a gasification layer (including an oxidation layer and a reduction layer) from top to bottom. The flue gas purification of the pyrolysis furnace usually adopts a multi-stage treatment process, and is purified through secondary combustion, rapid cooling, denitrification, dust removal, alkaline washing and activated carbon adsorption.

[0003] However, the current solid waste recycling pyrolysis furnace flue gas purification needs to pass the flue gas into the interior of the exhaust pipe and cool the flue gas through the spraying equipment. On the other hand, water can take away the particulate matter in the flue gas during spraying to achieve the purpose of dust reduction. The nozzle is installed at the inner top of the exhaust pipe. After the flue gas enters, it can only move horizontally. The lighter particles in the flue gas are located in the upper part of the flue gas, that is, close to the nozzle. The water sprayed by the nozzle first reduces the dust of the small particles in the upper layer of the flue gas. The water after dust reduction contains small particles. When the water is sprayed to the lower layer of the flue gas, the small particles in the water will affect the cleaning of large particles in the lower flue gas, and The smoke is not easily changed in direction inside the exhaust pipe when being discharged, the water sprayed from the nozzle is difficult to mix completely with the smoke, and the smoke and water are not easy to be stirred and mixed in the pipe, resulting in poor dust reduction and cooling effects. Moreover, the smoke is easily adhered to the inner wall of the exhaust pipe due to long-term smoke exhaust, which is difficult to clean and affects the smoke emission rate. The water after dust reduction is filtered through filter cotton, and the particles in the water will adhere to the filter cotton. After the filter cotton absorbs water, it affects the flow of water. There is no component for squeezing the filter cotton, which easily causes water accumulation inside the horizontally installed exhaust pipe, resulting in a smaller exhaust space of the exhaust pipe, affecting the dust reduction and cooling of the smoke.

[0015] The beneficial effects of the present invention are: 1. The waste article recycling pyrolysis furnace flue gas purification system for preventing and controlling solid waste pollution described in the present invention has a dust reduction mechanism installed on the outer shell, which transports the flue gas discharged from the pyrolysis furnace to the inside of the outer shell through the flue gas inlet pipe, and starts the motor to realize the rotation of gear one and gear two, thereby realizing the rotation of the spiral auger between the rotating rod one and the rotating rod two, and the rotating rod one is connected to the water inlet pipe through a rotary joint, so that cold water can be transported from the water inlet pipe to the water channel inside the spiral auger, and the spiral auger rotates while spraying water at the nozzle.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1-11As shown, the waste recycling pyrolysis furnace flue gas purification system for preventing and controlling solid waste pollution described in the present invention includes a bracket 1, a conveying mechanism 2 installed on the bracket 1, and a dust reduction mechanism 3 and a water filtering mechanism 5 installed on the conveying mechanism 2; the conveying mechanism 2 includes a shell 201, the shell 201 is fixedly connected to the bracket 1, and the dust reduction mechanism 3 includes a rotating rod 1 304 and a rotating rod 2 308. The centers of the two ends of the shell 201 are relatively rotatably connected to the rotating rod 1 304 and the rotating rod 2 308. The rotating rod 1 304 located inside the shell 201 is connected to the rotating rod 1 304. The first and second rotating rods 308 are fixedly connected with a connecting plate 309, and a spiral auger 310 is fixedly connected between the two connecting plates 309. A water channel 311 is opened inside the rotating rod 1 304, the connecting plate 309 on the rotating rod 1 304, and the spiral auger 310. A plurality of nozzles 312 connected to the water channel 311 are equidistantly installed on the inner side of the spiral auger 310. A plurality of arc-shaped blades 313 are equidistantly fixedly connected to the inner side of the spiral auger 310. A rotary joint 306 is installed at the end of the rotating rod 1 304, away from the rotating rod 1 3 04 is provided with a water inlet pipe 302 on the rotary joint 306 at one end; the conveying mechanism 2 also includes a smoke inlet pipe 203 and a smoke exhaust pipe 202, and the smoke inlet pipe 203 and the smoke exhaust pipe 202 are installed at both ends of the shell 201, and the smoke inlet pipe 203 is connected with a connecting pipe 204; the dust reduction mechanism 3 also includes a motor 301, and the motor 301 is installed at the end of the shell 201. Two gears 303 are provided at both ends of the shell 201, one of the gears 303 is key-connected to the motor 301, and the other gear 303 is key-connected to the motor 301. It is rotatably connected to the housing 201, and the rotating rod 1 304 and the rotating rod 2 308 are both keyed to the gear 2 305, and the two sets of the gear 2 305 are meshed with the gear 1 303; the dust reduction mechanism 3 also includes a support plate 307, and the water inlet pipe 302 is welded with a support plate 307 whose bottom is flush with the bottom of the bracket 1; the dust reduction mechanism 3 also includes a swing iron 314, and the side of the spiral auger 310 is equidistantly connected to the swing iron 314, the cross-section of the swing iron 314 is an inverted T-shaped structure, and the surface of the swing iron 314 is a mesh structure;After the solid waste is burned and cracked in the pyrolysis furnace, flue gas will be generated. The flue gas pipe is connected to the connecting pipe 204. At this time, the sealing plate 407 is in a sealed state against the ash outlet 408, and the spring 405 is opened, so that the flue gas will be sent into the interior of the shell 201 from the smoke inlet pipe 203. The support plate 307 is fixed to the ground to ensure that the water inlet pipe 302 does not rotate. The rotating rod 1 304 is connected to the water inlet pipe 302 through the rotary joint 306. The water inlet pipe 302 is connected to the water source to enable water to flow from the water inlet pipe 302 to the inside of the rotating rod 1 304 and finally to the water channel 311 inside the connecting plate 309 and the spiral auger 310. At this time, after the water channel 311 is connected to the water, it can be sprayed out from the nozzles 312 equidistantly installed on the spiral auger 310. After the flue gas enters the interior of the shell 201, the motor 301 is started to realize that the gear 1 303 drives the gear 2 305 to rotate, further realizing the rotating rod 1 304 drives the auger 310 to rotate. The speed of the auger 310 can be controlled according to the speed of the motor 301, ensuring a more even mixing of the flue gas and water. This facilitates the treatment of large and small particles in the flue gas and prevents the removal of heavier particles in the lower layer. The faster the motor 301 rotates, the faster the blades 313 on the auger 310 accelerate the flow speed and direction of the flue gas. The treated flue gas is discharged from the exhaust pipe 202. The water sprayed from the nozzle 312 treats the particles in the flue gas and then flows into the drain outlet 505. The swing iron 314 on the auger 310 expands outward due to centrifugal force when the motor 301 rotates faster, and droops when it rotates slower. In either state, it strikes the water sprayed from the nozzle 312, increasing the contact area between the water and the flue gas, facilitating the treatment of particles. It also fanns the air, increasing the flow speed of the flue gas.

[0023] Specifically, such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the water filtering mechanism 5 includes a bottom shell 501, which is connected to the bottom center of the outer shell 201, and a drain port 505 penetrating the bottom shell 501 is provided at the bottom of the outer shell 201. The bottom of the bottom shell 501 is fixedly connected to a bottom plate 507 by screws, and a sponge strip 504 is placed inside the bottom shell 501. A pressure plate 506 with holes is placed on the sponge strip 504. A drain pipe 502 is connected to the bottom center of the bottom plate 507, and a serpentine-shaped deodorizing pipe 503 is threadedly connected to the drain pipe 502; a pressing mechanism 6 is provided on the bottom shell 501, and the pressing mechanism 6 includes a gear Three 601, both ends of the shell 201 are rotatably connected to the gear three 601 through the rotating shaft 602, and the two gear three 601 are respectively engaged with the two gear one 303. The rotating shaft 602 on the two bottom shells 501 is fixedly connected with an eccentric rod 603, and the eccentric rod 603 is located on the top of the pressure plate 506; the lengths of the two eccentric rods 603 are equal, and the diameters of the two gear three 601 are greater than the diameters of the two gear one 303; the water after treating the particulate matter in the flue gas flows from the shell 201 to the drain port 505, and further flows into the interior of the bottom shell 501, the water is absorbed by the sponge strip 504, and the particles in the water are absorbed by the sponge strip 504. The particles are filtered by the sponge strip 504, and the pressure plate 506 on the top of the sponge strip 504 can also leak water and filter. When the water on the sponge strip 504 absorbs too much and affects the flow of water, then when the motor 301 drives the gear 1 303 to rotate, the opportunity drives the gear 2 305 to rotate and also drives the gear 3 601 at both ends of the shell 201 to rotate. When the gear 3 601 rotates, it drives the two rotating shafts 602 on both sides of the bottom shell 501 to rotate at the same time. Since the two eccentric rods 603 are welded to the rotating shaft 602, and the eccentric rod 603 is located at the top of the pressure plate 506, when the rotating shaft 602 is driven, the two eccentric rods 603 intermittently press the pressure plate 506 Press, and the pressure plate 506 is further lowered to squeeze the sponge strip 504. The water on the sponge strip 504 is squeezed out and discharged from the drain pipe 502, avoiding the accumulation of sewage inside the shell 201 and reducing the space for smoke emission. The particulate matter is filtered by the sponge strip 504, and the diameter of gear three 601 is larger than the diameter of gear one 303, so that the gear three 601 rotates slower, increasing the pressing interval time, and the treated water is discharged through the odor-proof pipe 503. There is always water at the lowest point of the serpentine structure of the odor-proof pipe 503, which can avoid smoke overflow. When the sponge strip 504 needs to be cleaned, the bottom plate 507 can be disassembled to remove the particulate matter cleaned by the sponge strip 504.

[0024] Specifically, such as Figure 2 、 Figure 8 、 Figure 9 、 Figure 10 ,and Figure 11As shown, a cleaning mechanism 4 is installed on the smoke inlet pipe 203, and the cleaning mechanism 4 includes an ash outlet 408. The bottom of the smoke inlet pipe 203 is provided with an ash outlet 408 corresponding to the connecting pipe 204. The ash outlet 408 is in contact with a sealing plate 407 with an arc structure. The interior of the smoke inlet pipe 203 is slidably connected to a baffle 406 fixedly connected to the sealing plate 407. The interior of the smoke inlet pipe 203 is slidably connected to a scraping ring 403 with an annular structure. The scraping ring 403 is fixedly connected to the sealing plate 407 by a bridge plate 404. The end of the smoke inlet pipe 203 is slidably connected to a pull rod 401 fixed to the baffle 406. A cold water pipe 402 is spirally wound around the smoke inlet pipe 203. The cleaning mechanism 4 also includes a spring 405, which is clamped between the smoke inlet pipe 203 and the baffle 406. The exhaust assembly of the pyrolysis furnace is connected to the connecting pipe 204. When the smoke is introduced, the spring inside the smoke inlet pipe 203 is pressed. Under the action of the elastic force of 405, the sealing plate 407 seals the ash outlet 408 to prevent smoke leakage. The smoke is transported from the smoke inlet pipe 203 to the inside of the shell 201. The inner wall of the smoke inlet pipe 203 that transports smoke for a long time will adhere to the particles and reduce the smoke inlet diameter of the smoke inlet pipe 203. At this time, the pull rod 401 on the smoke inlet pipe 203 can be pulled to realize the contraction of the spring 405. The baffle 406 moves to the right, and the sealing plate 407 slowly opens the ash outlet 408. When 406 and the sealing plate 407 move, the bridge plate 404 drives the scraper ring 403 to slide on the inner wall of the smoke inlet pipe 203. When the scraper ring 403 moves, the internal smoke and dust of the smoke inlet pipe 203 is processed. When the scraper ring 403 reaches the ash outlet 408, the scraped smoke and dust are discharged. After the pull rod 401 is released, the spring 405 resets, and the sealing plate 407 seals the ash outlet 408 again to avoid long-term smoke leakage. The unblocked smoke inlet pipe 203 is conducive to the entry of smoke.

[0025] When the present invention is in use, first, solid waste is burned and cracked through the pyrolysis furnace to generate flue gas, and the flue gas pipe is connected to the connecting pipe 204. At this time, the sealing plate 407 is sealed to the ash outlet 408, and the spring 405 is opened, so that the flue gas will be sent from the smoke inlet pipe 203 to the interior of the shell 201, and the support plate 307 is fixed to the ground to ensure that the water inlet pipe 302 does not rotate, and the rotating rod 1 304 is connected to the water inlet pipe 302 through the rotary joint 306, and the water inlet pipe 302 is connected to the water source to enable water to flow from the water inlet pipe 302 to the interior of the rotating rod 1 304, and finally to the water channel 311 inside the connecting plate 309 and the spiral auger 310. At this time, after the water channel 311 is connected to water, it can be sprayed from the nozzles 312 equidistantly installed on the spiral auger 310. After the flue gas enters the interior of the shell 201, the motor 301 is started to enable the gear 1 303 to drive the gear 2 305 to rotate, and further The rotating rod 304 drives the spiral auger 310 to rotate, and the rotation speed of the spiral auger 310 can be controlled according to the rotation speed of the motor 301, so that the smoke and water are mixed more evenly, which is beneficial to the treatment of large and small particles in the smoke and prevents the heavy particles in the lower layer from being difficult to be taken away. The faster the motor 301 rotates, the blades 313 on the spiral auger 310 can accelerate the flow speed and flow direction of the smoke, and the treated smoke is discharged from the smoke exhaust pipe 202. The water sprayed by the nozzle 312 treats the particles in the smoke and then flows into the inside of the drain port 505. The swing iron 314 on the spiral auger 310 expands outward due to centrifugal force when the motor 301 rotates faster, and is in a drooping state when it is slower. In either state, the water sprayed by the nozzle 312 can be knocked to increase the contact area between water and smoke, which is beneficial to the treatment of particles. At the same time, it can also fan the air and increase the flow speed of the smoke. Then, the water after treating the particulate matter in the flue gas flows from the outer shell 201 to the drain port 505, and further flows into the interior of the bottom shell 501, where the water is absorbed by the sponge strip 504, and the particulate matter in the water is filtered by the sponge strip 504. The pressure plate 506 on the top of the sponge strip 504 can also leak water and filter. When the water on the sponge strip 504 absorbs too much and affects the flow of water, when the motor 301 drives the gear 1 303 to rotate, the gear 2 305 will be driven to rotate, which will also drive the gear 3 601 at both ends of the outer shell 201 to rotate. When the gear 3 601 rotates, it drives the two rotating shafts 602 on both sides of the bottom shell 501 to rotate at the same time. Since the two eccentric rods 603 are welded to the rotating shaft 602, and the eccentric rod 603 is located on the top of the pressure plate 506, when the gear 3 601 rotates, the gear 3 601 on both sides of the bottom shell 501 will rotate at the same time. After the shaft 602 is driven, the two eccentric rods 603 intermittently press the pressure plate 506. The further downward movement of the pressure plate 506 squeezes the sponge strip 504, and the water on the sponge strip 504 is squeezed out and discharged from the drain pipe 502, thereby preventing sewage from accumulating inside the housing 201 and reducing the space for smoke emission. The particulate matter is filtered by the sponge strip 504. The diameter of the gear three 601 is larger than that of the gear one 303, so that the gear three 601 rotates slowly, increasing the pressing interval time. The treated water is discharged through the deodorizing pipe 503. There is always water at the lowest point of the deodorizing pipe 503 with a serpentine structure, which can prevent smoke from overflowing. When the sponge strip 504 needs to be cleaned, the bottom plate 507 can be disassembled to remove the particulate matter cleaned by the sponge strip 504. Finally, the smoke exhaust assembly of the pyrolysis furnace is connected to the connecting pipe 204. When the smoke is introduced, the sealing plate 407 seals the ash outlet 408 under the elastic force of the spring 405 inside the smoke inlet pipe 203 to prevent smoke leakage. The smoke is transported from the smoke inlet pipe 203 to the inside of the shell 201. The inner wall of the smoke inlet pipe 203 that transports smoke for a long time will adhere to the particles and reduce the smoke intake diameter of the smoke inlet pipe 203. At this time, the pull rod 401 on the smoke inlet pipe 203 can be pulled to realize the contraction of the spring 405, and the baffle 406 is further moved to the right, and the sealing plate 407 slowly opens the ash outlet 408, and when the baffle 406 and the sealing plate 407 move, the bridge plate 404 drives the scraper ring 403 to slide on the inner wall of the smoke inlet pipe 203, and when the scraper ring 403 moves, the internal smoke and dust of the smoke inlet pipe 203 is processed. When the scraper ring 403 reaches the ash outlet 408, the scraped smoke and dust are discharged. After releasing the pull rod 401, the spring 405 resets, and the sealing plate 407 seals the ash outlet 408 again to avoid long-term smoke leakage. The unblocked smoke inlet pipe 203 is conducive to the entry of smoke.
