Description

Technical Field

[0001] The invention belongs to the technical field of incineration equipment, in particular to a fly ash reduction treatment device for garbage combustion. Background Art

[0002] Waste incineration technology has become a mainstream method for treating municipal solid waste due to its advantages in waste reduction, harmlessness, and high degree of resource utilization. However, fly ash is inevitably generated during the incineration process. When waste is burned at high temperatures in the incinerator, the non-combustible inorganic components contained in the waste are physically broken down by the high-temperature flames and airflow disturbances, forming fine particles. Some lightweight inorganic particles are directly carried by the flue gas, becoming the main source of fly ash.

[0003] At present, the treatment of incineration fly ash mainly focuses on terminal purification and subsequent disposal. After the fly ash enters the flue with the flue gas, it is separated through multi-stage purification equipment such as cyclone separators, semi-dry deacidification towers, electrostatic precipitators, bag dust collectors, etc.

[0004] Although existing treatment systems can achieve the separation and disposal of fly ash, the following problems still exist when fly ash passes through the flue with flue gas and finally enters the purification system:

[0005] When fly ash flows through the flue, it will adhere to the inner wall of the flue, forming ash accumulation. Long-term operation will cause the flue cross-sectional area to gradually decrease, the flue gas flow resistance to increase, and even cause local blockage, seriously affecting the stable operation of the incineration system, increasing the frequency of shutdowns for cleaning and operation and maintenance costs.

[0006] At the same time, if fly ash is not effectively reduced before entering the final purification equipment, a large amount of fly ash will directly enter the dust collector, such as the bag filter. This will cause the dust layer on the filter bag surface to increase rapidly, shorten the cleaning cycle, increase filter bag wear, and significantly increase the equipment's operating resistance. This not only increases the energy consumption of auxiliary equipment such as the induced draft fan, but also leads to a surge in system operating costs due to frequent filter bag replacement.

When it is processed by the subsequent treatment system, it not only reduces the filter material loss of the subsequent treatment system, but also reduces the equipment operation resistance, while improving the purification effect of the flue gas.

[0041] 2. The fly ash reduction and treatment device for garbage combustion described in the present invention can blow out the fly ash blocked in the filter holes by reverse blowing the air flow through the air holes of the semicircular bin, and promptly remove the blocked fly ash in the filter holes to avoid fly ash blocking the filter holes and reduce the permeability of the filter cartridge. At the same time, through the first pipe joint installed on the rectangular bin, fly ash and gas can be extracted through the rectangular bin for collection, avoiding the accumulation of fly ash inside the rectangular bin, which may cause the fly ash to still adhere to the filter cartridge.

[0042] 3. The fly ash reduction treatment device for garbage combustion described in the present invention can mix the flue gas with the gas because the gas is discharged together with the flue gas, thereby diluting the flue gas. Therefore, when the flue gas is treated by a subsequent treatment system, the purification effect of the flue gas can be improved, and at the same time, the filter material loss of the subsequent treatment system can be reduced, and the equipment operation resistance is also reduced.

DETAILED DESCRIPTION

[0056] 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.

[0057] like Figures 1 to 11 As shown, a fly ash reduction treatment device for garbage combustion according to the present invention, as an embodiment of the present invention, comprises a combustion device 1; a smoke pipe 11 is eccentrically provided on the top of the combustion device 1;

[0058] A processing mechanism is provided on the top of the combustion device 1; the processing mechanism includes a circular silo 2, and the circular silo 2 is arranged concentrically with the combustion device 1; a circular plate 21 rotates in the circular silo 2, and the circular plate 21 is driven by a first motor 22, and the first motor 22 is installed on the top of the circular silo 2;

[0059] The inner wall of the circular plate 21 is provided with a plurality of through holes 23 in an annular shape. The smoke pipe 11 extends to the bottom of the circular plate 21 and is connected to one of the through holes 23. A processing assembly is mounted on the left side of the first motor 22. The processing assembly includes a first vertical cylinder 3, and the inner diameter of the first vertical cylinder 3 is the same as the diameter of the through hole 23.

[0060] A cylindrical block 31 slides in the first vertical cylinder 3; an annular groove is provided in the cylindrical block 31; a filter cartridge 32 is provided in the annular groove to rotate, and the cylindrical block 31 extends from the top and bottom of the filter cartridge 32;

[0061] The top and bottom of the cylindrical block 31 are located on both sides of the filter cartridge 32 and are fixed with semicircular plates 33, and the semicircular plates 33 are in close contact with the filter cartridge 32;

[0062] A driving wheel 34 rotates inside the cylindrical block 31 and is tangential to the surface of the filter cartridge 32 . The driving wheel 34 is driven by a second motor installed inside the cylindrical block 31 .

[0063] The ends of both sides of the filter cartridge 32 are located in the cylindrical block 31 and are provided with curved grooves 35, and the curved grooves 35 extend to the top of the cylindrical block 31; the curved grooves 35 are fixed with guide tubes 36, and the guide tubes 36 extend upward;

[0064] An arch frame 37 is installed on the top of the first vertical tube 3; two first cylinders 38 are installed on the arch frame 37, and the other side of the first cylinder 38 is installed on the top of the column block 31;

[0065] A cleaning assembly is installed in the filter cartridge 32, and the cleaning assembly is used to clean the filter cartridge 32;

[0066] In this embodiment, the cleaning assembly includes a semicircular bin 4;

[0067] The semicircular bin 4 is fixedly installed in the annular groove and fits in with the annular groove and the two semicircular plates 33 above; the top of the semicircular bin 4 is provided with evenly arranged air holes 41;

[0068] Two curved pipes 42 are provided at both ends of the semicircular silo 4, and the curved pipes 42 are installed inside the cylindrical block 31 and extend to the top of the cylindrical block 31;

[0069] A rectangular bin 43 is fixedly mounted on the top of the semicircular bin 4; the rectangular bin 43 is located between the two conduits 36; a first pipe joint 44 is mounted on the top of the rectangular bin 43, and the first pipe joint 44 is connected to an external vacuum cleaner;

[0070] During implementation, when burning garbage, first put the garbage into the combustion equipment 1, burn the garbage, and control the processing mechanism to work at the same time. When the processing mechanism works, it will control the first motor 22 to drive the circular plate 21 to rotate cyclically and intermittently. The fly ash generated when the garbage is burned will be discharged from the smoke pipe 11 along with the smoke. During the cyclic and intermittent rotation of the circular plate 21, it will drive the through hole 23 to rotate intermittently. When the through hole 23 rotates to the top of the smoke pipe 11, the circular plate 21 stops rotating first and then continues to rotate intermittently. When the circular plate 21 stops rotating, part of the smoke in the smoke pipe 11 will enter the through hole 23 passing through the smoke pipe 11. Since there are multiple through holes 23, when each through hole 23 passes through the smoke pipe 11 and stops, the smoke inside the smoke pipe 11 will enter the through hole 23. During the rotation of the circular plate 21, the through hole 23 and the smoke entering the through hole 23 will be driven to rotate. By controlling the through hole 23 to circulate through the smoke pipe 11, the smoke can be continuously brought out, thereby avoiding reducing the flow rate of the smoke when it flows out.

[0071] Specifically, when the smoke follows the through hole 23 and rotates to the bottom of the first vertical cylinder 3 and is aligned with the first vertical cylinder 3, the control plate 21 stops rotating and the first cylinder 38 is controlled to extend. The extended first cylinder 38 pushes the cylindrical block 31 downward, and the downward-moving cylindrical block 31 simultaneously drives the filter cartridge 32, the conduit 36, the elbow 42, the semicircular plate 33, the semicircular bin 4 and the rectangular bin 43 downward. The downward-moving cylindrical block 31 moves down into the through hole 23 below and gradually moves down along the through hole 23. The block 31 will gradually squeeze the flue gas inside the through hole 23. When the flue gas is squeezed, the filter cartridge 32 partially extends to the bottom of the cylindrical block 31, so the squeezed flue gas will enter the filter cartridge 32 through the filter holes on the filter cartridge 32 at the bottom of the cylindrical block 31, and the fly ash will be filtered on the outside of the filter cartridge 32. Since the curved groove 35 provided in the cylindrical block 31 is connected to the conduit 36, the flue gas entering the filter cartridge 32 will enter the conduit 36 ​​and then be guided into the purification equipment through the conduit 36 ​​for purification.

[0072] More specifically, during the downward movement of the cylindrical block 31 in the through hole 23, the second motor is controlled to drive the driving wheel 34 to rotate. Since the driving wheel 34 is tangential to the surface of the filter cartridge 32, the filter cartridge 32 is driven to circulate in the annular groove. Therefore, the filter cartridge 32 exposed below the cylindrical block 31 is replaced, thereby avoiding long-term filtration of the flue gas by the same part of the filter cartridge 32, which may cause blockage. During the rotation of the filter cartridge 32, it gradually rotates along the cylindrical block 31 into the annular groove. Therefore, the cylindrical block 31 in contact with the filter cartridge 32 can scrape the surface of the filter cartridge 32, thereby scraping off the fly ash adhering to the filter cartridge 32 and dropping it into the through hole 23.

[0073] Furthermore, in the process of exhausting the smoke, the bent pipe 42 is connected to the external air source, and the external air will enter the semicircular bin 4 through the bent pipe 42. Since both ends of the semicircular bin 4 are in contact with the semicircular plate 33, the air entering the semicircular bin 4 will be discharged through the air holes 41 at the top of the semicircular bin 4. Since the filter cartridge 32 is circulated, the filter cartridge 32 will circulate through the semicircular bin 4. When the air in the semicircular bin 4 is blown out, it will be blown out from the filter holes on the rotating filter cartridge 32, so that the filter holes passed through can be dredged from the inside of the filter cartridge 32. If fly ash is blocked in the filter holes, the gas in the filter holes will blow the blocked fly ash out and blow it into the rectangular bin 43. By connecting the first pipe joint 44 with the external dust collector, the air and fly ash entering the rectangular bin 43 can be extracted, thereby discharging the fly ash while dredging the filter holes, and at the same time ensuring the permeability of the filter holes.

[0074] Furthermore, after the cylindrical block 31 drives the filter cartridge 32 to move down to the bottom of the through hole 23, the first cylinder 38 is controlled to drive the cylindrical block 31 to move up into the first vertical cylinder 3. Then, the circular plate 21 is controlled to continue to rotate intermittently in a cycle. When the next through hole 23 carrying smoke rotates to the bottom of the first vertical cylinder 3, the above operation is repeated. When the through hole 23 from which the smoke is discharged rotates again to the top of the smoke pipe 11, the smoke will continue to enter the through hole 23, and the cycle continues.

[0075] In general, by utilizing the intermittent docking design of the through holes 23 of the circular plate 21 and the smoke pipe 11, the smoke generated by the combustion is dispersed into multiple through holes 23, avoiding the high flow impact of a single channel; this diversion mode not only ensures the continuous discharge of smoke, but also reduces the fly ash concentration carried by a single flue gas, thereby reducing the initial load for subsequent filtration treatment; at the same time, by utilizing the filter cartridge 32 to intercept the fly ash, the fly ash can be blocked on the outside of the filter cartridge 32, scraped and dropped into the through holes 23 for collection, and the discharged smoke enters the subsequent treatment system through the conduit 36; this pre-separation at the outlet of the combustion equipment 1 greatly reduces the amount of fly ash entering the flue, avoids the adhesion and blockage of the inner wall of the flue from the source, and at the same time, part of the fly ash inside the smoke is removed, and when it is processed by the subsequent treatment system, it not only reduces the filter material loss of the subsequent treatment system, but also reduces the equipment operation resistance, while improving the purification effect of the smoke;

[0076] At the same time, by utilizing the air holes 41 of the semicircular bin 4 to blow the air in reverse, the fly ash clogged in the filter holes can be blown out, and the clogged fly ash in the filter holes can be cleared in time to avoid fly ash clogging the filter holes and reduce the permeability of the filter cartridge 32. At the same time, through the first pipe joint 44 installed on the rectangular bin 43, the fly ash and gas can be extracted and collected through the rectangular bin 43 to avoid the fly ash accumulating inside the rectangular bin 43, which may cause the fly ash to still adhere to the filter cartridge 32.

[0077] As an embodiment of the present invention; a connecting pipe 45 is installed at the bottom of the semicircular silo 4;

[0078] A rotating shaft 46 is mounted at the bottom of the connecting pipe 45; rotating drums 47 are rotatable on both sides of the rotating shaft 46; the rotating drums 47 are fixedly connected to evenly arranged conical shafts 48, and the conical shafts 48 are made of rubber material and engage with the filter holes on the filter drum 32;

[0079] In this embodiment, the connecting pipe 45 is connected to the interior of the semicircular silo 4;

[0080] The connecting pipe 45 is provided with a blowpipe 49 , and the outlet pipe is connected to the connecting pipe 45 and faces the curved groove 35 ;

[0081] During implementation, since the rotating shaft 46 is fixedly connected to the connecting pipe 45 fixedly connected to the semicircular silo 4, and the rotating drums 47 are rotatable on both sides of the rotating shaft 46, and the conical shaft 48 fixedly connected to the rotating drum 47 is engaged with the filter holes on the filter drum 32; therefore, during the rotation of the filter drum 32, the filter drum 32 will drive the rotating drum 47 to rotate, and the rotating shaft 46 on the rotating drum 47 will be inserted into the filter holes on the filter drum 32 in turn, so that the filter holes can be dredged and the fly ash blocked in the filter holes can be pushed out, thereby avoiding the situation that the filter holes are blocked during the process of the smoke entering the filter drum 32, and the smoke cannot enter the filter drum 32;

[0082] Since the connecting pipe 45 is connected to the interior of the semicircular silo 4, part of the gas inside the semicircular silo 4 will enter the connecting pipe 45 and then be blown out through the blowpipe 49. Since the blowpipe 49 is directed toward the curved groove 35, when the blowpipe 49 blows, the gas will enter the curved groove 35. At the same time, according to Bernoulli's principle, when the blowpipe 49 blows, it can drive the surrounding smoke into the curved groove 35 and then be discharged through the conduit 36. Therefore, when the cylindrical block 31 drives the annular cylinder to move upward, the gas inside the filter cylinder 32 will not be discharged from the filter hole.

[0083] At the same time, since the gas is discharged together with the flue gas, the flue gas and the gas can be mixed, thereby diluting the flue gas. Therefore, when the flue gas is treated by the subsequent treatment system, the purification effect of the flue gas can be improved, and at the same time, the filter material loss of the subsequent treatment system can be reduced, and the equipment operation resistance can be reduced.

[0084] As an embodiment of the present invention, a first curved plate 441 is fixedly connected to the bottom of the first pipe joint 44;

[0085] A brush layer 442 is fixedly connected to the bottom of the first arc-shaped plate 441 , and the brush layer 442 is located directly below the first pipe joint 44 ;

[0086] During implementation, since the first curved plate 441 is provided at the bottom of the first pipe joint 44, during the suction process of the first pipe joint 44, the first curved plate 441 can guide the gas and fly ash, so that the fly ash can accurately enter the interior of the first pipe joint 44. At the same time, since the brush layer 442 is fixedly connected to the bottom of the first curved plate 441, when the rotating filter cartridge 32 passes through the brush layer 442, the brush layer 442 can brush the filter cartridge 32, thereby improving the cleaning effect of the filter cartridge 32.

[0087] As an embodiment of the present invention; the filter cartridge 32 is located on both sides of the inner wall of the first vertical cylinder 3 Kun opened with an arc groove 5, and the top of the arc groove 5 is provided with a downward protrusion;

[0088] A second arc-shaped plate 51 is provided on the outside of one of the arc-shaped grooves 5, and a groove is provided on the top of the second arc-shaped plate 51, and the diameter of the groove is the same as the outer diameter of the filter cartridge 32;

[0089] The second arc-shaped plate 51 is initially located in the adjacent arc-shaped groove 5;

[0090] A second cylinder 52 is installed on the top of the silo 2, and the other side of the second cylinder 52 is fixed on the second curved plate 51;

[0091] A collecting bin 53 is fixed on one side of the other arc-shaped slot 5, and the collecting bin 53 is connected to the arc-shaped slot 5; the collecting bin 53 is a drawer type;

[0092] In this embodiment, a collecting tube 6 is provided on one side close to the smoke pipe 11;

[0093] The bottom of the silo 2 is provided with a threaded groove, and the collecting cylinder 6 is engaged with the threaded groove through a thread. In the initial state, the threaded cylinder is opposite to one of the through holes 23.

[0094] A second pipe joint 61 is installed at the bottom of the collecting cylinder 6, and the second pipe joint 61 is connected to an external vacuum cleaner;

[0095] During implementation, after the first cylinder 38 drives the column block 31 to move up to the initial position, the second cylinder 52 is controlled to extend, and the extended second cylinder 52 will push the second curved plate 51 to move, and the moving second curved plate 51 will gradually extend into the first vertical cylinder 3, and gradually pass under the column block 31 and the filter cartridge 32, and fit with the bottom surfaces of the column block 31 and the filter cartridge 32. In this process, the bottom surfaces of the column block 31 and the filter cartridge 32 can be scraped, so that the fly ash remaining at the bottom of the column block 31 and the bottom of the filter cartridge 32 can be pushed out and gradually pushed into the collection bin 53. When the second curved plate 51 gradually approaches the collection bin 53, the second curved plate 51 will gradually pass through the arc groove 5 close to the collection bin 53 and push the fly ash into the collection bin 53, and then the second cylinder 52 is controlled to return to its initial state;

[0096] Specifically, since a collecting tube 6 is provided on the side close to the smoke pipe 11, when the through hole 23 processed by the processing mechanism rotates to above the collecting tube 6, the fly ash remaining in the through hole 23 will fall into the collecting tube 6. At the same time, the second pipe joint 61 is connected to the external vacuum cleaner, and the fly ash and gas in the collecting tube 6 and the through hole 23 can be sucked out through the second pipe joint 61, thereby preventing fly ash from remaining in the through hole 23.

[0097] As an embodiment of the present invention, a second vertical cylinder 7 is installed above the smoke pipe 11 at the top of the silo 2, and the inner diameter of the second vertical cylinder 7 is the same as the diameter of the through hole 23;

[0098] A third cylinder 71 is installed on the second vertical cylinder 7, and a push block 72 is installed at the bottom of the third cylinder 71;

[0099] In this embodiment, a driving shaft 73 is fixedly connected to the bottom of the circular plate 21;

[0100] The drive shaft 73 extends into the combustion device 1; a curved scraper 74 is fixedly connected to one side of the drive shaft 73 extending into the drive device; the bottom of the push block 72 is a curved surface, and the diameter of the curved surface is the same as the diameter of the curved scraper 74;

[0101] During implementation, as the circular plate 21 rotates, the arc-shaped scraper 74 is driven to rotate via the drive shaft 73. The rotating arc-shaped scraper 74 scrapes the interior of the combustion device 1, thereby scraping off the fly ash adhered to the interior of the combustion device 1.

[0102] When the garbage combustion is completed, the third cylinder 71 is controlled to extend. The extended third cylinder 71 will drive the push plate to move downward. The downward push plate will first pass through the through hole 23, then move down into the smoke pipe 11, and then continue to move down along the smoke pipe 11 and scrape the inside of the smoke pipe 11, so that the fly ash adhered to the inside of the smoke pipe 11 can be pushed into the combustion equipment 1. When the third cylinder 71 is extended to the limit position, the bottom end face of the push plate fits with the surface of the arc scraper 74, so during the rotation of the arc scraper 74, the fly ash on the push plate can be scraped off.
