Description

Technical Field

[0001] This invention belongs to the field of incineration equipment technology, specifically a fly ash reduction treatment device for waste incineration. Background Technology

[0002] Waste incineration technology has become one of the mainstream methods for urban waste treatment due to its advantages of volume reduction, harmlessness, and high resource recovery. However, fly ash is inevitably generated during the waste 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 into fine particles under the influence of high-temperature flames and airflow disturbances; some of these lightweight inorganic particles are directly carried by the flue gas, becoming the main source of fly ash.

[0003] Currently, the treatment of incineration fly ash mainly focuses on end-of-pipe purification and subsequent disposal. After the fly ash enters the flue with the flue gas, it is separated by multi-stage purification equipment, such as cyclone separators, semi-dry desulfurization towers, electrostatic precipitators, and bag filters.

[0004] Although existing treatment systems can separate and dispose of fly ash, the following problems still exist in the process of fly ash passing through the flue with the flue gas and finally entering the purification system:

[0005] When fly ash flows through the flue, it adheres to the inner wall of the flue and forms ash accumulation. Long-term operation will cause the cross-sectional area of ​​the flue to gradually shrink, the airflow resistance to flue gas to increase, and even cause local blockage, which will seriously affect the stable operation of the incineration system, increase the frequency of shutdown for cleaning and maintenance costs.

[0006] Meanwhile, if fly ash is not effectively reduced before entering the end-of-pipe purification equipment, a large amount of fly ash will directly enter the dust collector, such as a bag filter. This will cause the ash layer thickness on the filter bag surface to increase rapidly, the cleaning cycle to shorten, the filter bag to wear more intensely, and the equipment operating resistance to rise significantly. This not only increases the energy consumption of auxiliary equipment such as induced draft fans, but also leads to a surge in system operating costs due to frequent filter bag replacements.

DETAILED DESCRIPTION

[0056] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application will be further described below in combination with specific embodiments.

[0057] As Figures 1 to 11 shown, the fly ash reduction treatment device for garbage combustion according to the application is an embodiment of the application; comprising a combustion equipment 1; the combustion equipment 1 is provided with a smoke pipe 11 eccentrically at the top;

[0059] A plurality of through holes 23 are arranged in the inner wall of the round plate 21 in an annular shape; the smoke pipe 11 extends to the bottom of the round plate 21 and communicates with one of the through holes 23; a processing assembly is installed on the left side of the first motor 22; the processing assembly comprises 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 is slidably arranged in the first vertical cylinder 3; an annular groove is arranged in the cylindrical block 31; a filter cylinder 32 is rotatably arranged in the annular groove, and the top and bottom of the filter cylinder 32 extend out of the cylindrical block 31;

[0061] Half round plates 33 are fixed on the top and bottom of the cylindrical block 31 and are attached to the filter cylinder 32;

[0062] A drive wheel 34 is rotatably arranged in the cylindrical block 31 and is tangent to the surface of the filter cylinder 32; the drive wheel 34 is driven by a second motor, and the second motor is installed inside the cylindrical block 31;

[0063] Bent grooves 35 are arranged in the filter cylinder 32 on both sides and extend to the top of the cylindrical block 31; a conduit 36 is fixed in each of the bent grooves 35 and extends upward;

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

[0065] A cleaning assembly is installed in the filter cylinder 32, and the cleaning assembly is used for cleaning the filter cylinder 32;

[0066] In this embodiment, the cleaning assembly comprises a half round bin 4;

[0067] The half round bin 4 is fixedly installed in the annular groove and is attached to the annular groove and the two half round plates 33 above; a plurality of air holes 41 are arranged on the top of the half round bin 4;

[0068] Two bent pipes 42 are arranged on both sides of the half round bin 4, and the bent pipes 42 are installed inside the cylindrical block 31 and extend above the cylindrical block 31;

[0069] The semi-circular bin 4 is fixedly installed with a rectangular bin 43 on the top; the rectangular bin 43 is located between two pipes 36; the rectangular bin 43 is installed with a first pipe joint 44 on the top, and the first pipe joint 44 is communicated with an external dust collector;

[0070] In the implementation, when the garbage is burned, the garbage is first placed in the burning device 1, and the garbage is burned, and at the same time, the processing mechanism is controlled to work. When the processing mechanism works, the first motor 22 drives the circular plate 21 to rotate intermittently, and the fly ash generated during the burning of the garbage is discharged from the smoke pipe 11 along with the flue gas. In the process of the intermittent rotation of the circular plate 21, the through holes 23 are intermittently rotated. When the through holes 23 rotate above the smoke pipe 11, the circular plate 21 first stops rotating, and then continues to rotate intermittently. When the circular plate 21 stops rotating, part of the flue gas in the smoke pipe 11 enters the through holes 23 passing through the smoke pipe 11. Since the number of through holes 23 is multiple, when each through hole 23 passes through the smoke pipe 11 and stops, the flue gas in the smoke pipe 11 enters the through hole 23. In the process of the rotation of the circular plate 21, the through holes 23 and the flue gas entering the through holes 23 are rotated. By controlling the through holes 23 to pass through the smoke pipe 11, the flue gas can be continuously discharged, so that the flow rate of the flue gas can be reduced when the flue gas flows out.

[0071] Specifically, when the flue gas rotates to below the first vertical cylinder 3 and is aligned with the first vertical cylinder 3, the circular plate 21 is controlled to stop rotating, and the first cylinder 38 is controlled to be elongated. The elongated first cylinder 38 pushes the cylindrical block 31 downward, and the downward cylindrical block 31 simultaneously drives the filter cylinder 32, the pipe 36, the elbow pipe 42, the semi-circular plate 33, the semi-circular bin 4 and the rectangular bin 43 to move downward. The downward cylindrical block 31 moves into the lower through hole 23 and gradually moves along the through hole 23. The downward cylindrical block 31 gradually extrudes the flue gas in the through hole 23. When the flue gas is extruded, since the filter cylinder 32 extends below the cylindrical block 31, the extruded flue gas enters the filter cylinder 32 through the filter holes on the bottom of the filter cylinder 32, and the fly ash is filtered outside the filter cylinder 32. Since the curved groove 35 in the cylindrical block 31 is communicated with the pipe 36, the flue gas entering the filter cylinder 32 enters the pipe 36, and then is introduced into the purification device for purification.

[0072] More specifically, in the process of the cylindrical block 31 descending in the through hole 23, the second motor is controlled to drive the driving wheel 34 to rotate. Since the driving wheel 34 is tangent to the surface of the filter cylinder 32, the filter cylinder 32 will rotate in the annular groove, thereby replacing the filter cylinder 32 exposed below the cylindrical block 31, avoiding the situation that the same part of the filter cylinder 32 filters the flue gas for a long time, thereby causing blockage. In the process of the rotation of the filter cylinder 32, the filter cylinder 32 will gradually rotate into the annular groove along the cylindrical block 31, so that the cylindrical block 31 attached to the filter cylinder 32 can scratch the surface of the filter cylinder 32, thereby scraping the fly ash adhered to the filter cylinder 32 and dropping into the through hole 23;

[0073] Further, in the process of discharging the flue gas, the elbow pipe 42 is connected with the external gas source, and the external gas enters the semicircular bin 4 through the elbow pipe 42. Since the two ends of the semicircular bin 4 are attached to the semicircular plate 33, the gas entering the interior of the semicircular bin 4 will be discharged through the air holes 41 at the top of the semicircular bin 4. Since the filter cylinder 32 rotates cyclically, the filter cylinder 32 will cyclically pass through the semicircular bin 4. When the gas in the semicircular bin 4 is blown out, it will be blown out from the filter holes in the rotating filter cylinder 32, so that the filter holes passing through the filter cylinder 32 can be dredged. If the filter holes are blocked by fly ash, the gas passing through the filter holes will blow out the blocked fly ash and blow it into the rectangular bin 43. By connecting the first pipe joint 44 with the external dust collector, the gas and fly ash entering the rectangular bin 43 can be sucked out, thereby dredging the filter holes while discharging the fly ash and ensuring the permeability of the filter holes;

[0074] Further, when the cylindrical block 31 drives the filter cylinder 32 to descend to the bottom of the through hole 23, the first air cylinder 38 is controlled to drive the cylindrical block 31 to ascend to the first vertical cylinder 3. Then, the circular plate 21 is controlled to continue to rotate intermittently. When the next through hole 23 carrying flue gas rotates below the first vertical cylinder 3, the above operation is repeated. When the through hole 23 from which the flue gas is discharged rotates above the smoke pipe 11 again, the flue gas will continue to enter the through hole 23, and the cycle continues.

[0075] In general, by utilizing the intermittent butt joint design of the through hole 23 of the circular plate 21 and the smoke pipe 11, the combustion generated flue gas is dispersed into multiple through holes 23, avoiding the high flow impact of a single channel; this shunt mode not only ensures the continuous discharge of flue gas, but also reduces the fly ash concentration carried by a single flue gas, reducing the initial load for subsequent filtration processing; at the same time, by utilizing the filter cartridge 32 to intercept fly ash, the fly ash can be blocked outside the filter cartridge 32 and fall into the through hole 23 for collection through scraping, and the discharged flue gas enters the subsequent processing 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, avoiding the adhesion and blockage of the inner wall of the flue from the source, and part of the fly ash inside the flue gas is removed, which not only reduces the filter material loss of the subsequent processing system when using the subsequent processing system for processing, but also reduces the equipment operation resistance, while improving the purification effect of the flue gas;

[0076] At the same time, by utilizing the air hole 41 of the semi-circular bin 4 to blow back through the airflow, the fly ash blocked in the filter hole can be blown out, and the blocked fly ash in the filter hole can be removed in time to avoid fly ash blocking the filter hole and reducing the permeability of the filter cartridge 32. At the same time, by installing the first pipe joint 44 on the rectangular bin 43, the fly ash and gas can be extracted through the rectangular bin 43 for collection, avoiding the accumulation of fly ash inside the rectangular bin 43, which may still adhere to the filter cartridge 32.

[0077] As an embodiment of the present application; the semi-circular bin 4 is provided with a connecting pipe 45 at the bottom;

[0078] The connecting pipe 45 is provided with a rotating shaft 46 at the bottom; the rotating shaft 46 is provided with a rotating drum 47 on both sides; the rotating drum 47 is provided with uniformly arranged conical shafts 48, and the conical shafts 48 are made of rubber material and are engaged with the filter holes on the filter cartridge 32;

[0079] In this embodiment, the connecting pipe 45 is in communication with the inside of the semi-circular bin 4;

[0080] The connecting pipe 45 is provided with a blowing pipe 49, and the outlet pipe is in communication with the connecting pipe 45 and faces the curved groove 35;

[0081] In the implementation, since the rotating shaft 46 is fixedly connected with the connecting pipe 45 fixedly connected to the semi-circular bin 4, and the rotating shaft 46 is provided with a rotating drum 47 on both sides, and the conical shafts 48 fixedly connected to the rotating drum 47 are engaged with the filter holes on the filter cartridge 32; therefore, in the process of rotating the filter cartridge 32, the filter cartridge 32 drives the rotating drum 47 to rotate, and the rotating shaft 46 on the rotating drum 47 is inserted into the filter holes on the filter cartridge 32 in turn, so that the filter holes can be dredged, and the fly ash blocked in the filter holes can be pushed out, avoiding the blockage of the filter holes during the process of the flue gas entering the inside of the filter cartridge 32, and the flue gas cannot enter the inside of the filter cartridge 32;

[0082] Since the connecting pipe 45 is in communication with the interior of the semicircular bin 4, part of the gas in the interior of the semicircular bin 4 will enter the interior of the connecting pipe 45 and then be blown out through the blowing pipe 49. Since the blowing pipe 49 is directed towards the curved groove 35, when the blowing pipe 49 blows gas, the gas will enter the curved groove 35, and at the same time, according to Bernoulli's principle, when the blowing pipe 49 blows gas, the surrounding flue gas can be brought into the curved groove 35 and then be discharged through the pipe 36. Therefore, when the cylindrical block 31 drives the annular cylinder to move upwards, the gas in the interior of 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, so that the flue gas can be diluted, thereby improving the purification effect of the flue gas when the flue gas is treated in the subsequent treatment system, reducing the loss of filter material of the subsequent treatment system, and reducing the operation resistance of the equipment.

[0084] As an embodiment of the present application, the first pipe joint 44 is fixedly connected with a first arc-shaped plate 441 at the bottom;

[0085] The first arc-shaped plate 441 is fixedly connected with a brush layer 442 at the bottom, and the brush layer 442 is located directly below the first pipe joint 44;

[0086] In the implementation, since the first arc-shaped plate 441 is arranged at the bottom of the first pipe joint 44, in the process of suction of the first pipe joint 44, the first arc-shaped plate 441 can guide the gas and fly ash to enter the interior of the first pipe joint 44 accurately, and since the brush layer 442 is fixedly connected at the bottom of the first arc-shaped plate 441, when the rotating filter cylinder 32 passes through the brush layer 442, the brush layer 442 can brush the filter cylinder 32, thereby improving the cleaning effect of the filter cylinder 32.

[0087] As an embodiment of the present application, arc-shaped grooves 5 are arranged in the inner wall of the first vertical cylinder 3 on both sides of the filter cylinder 32, and a downward protrusion is arranged at the top of the arc-shaped groove 5;

[0088] A second arc-shaped plate 51 is arranged outside one of the arc-shaped grooves 5, and a recess is arranged at the top of the second arc-shaped plate 51, and the diameter of the recess is the same as the outer diameter of the filter cylinder 32;

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

[0090] A second cylinder 52 is arranged at the top of the semicircular bin 2, and the other side of the second cylinder 52 is fixed to the second arc-shaped plate 51;

[0091] The other side of the arc-shaped groove 5 is fixedly connected with a collecting bin 53, and the collecting bin 53 is in communication with the arc-shaped groove 5; and the collecting bin 53 is of a drawer type.

[0092] In the embodiment, a collecting cylinder 6 is arranged near one side of the smoke pipe 11;

[0093] The bottom of the round bin 2 is provided with a threaded groove, and the collecting cylinder 6 is engaged with the threaded groove through threads; in the initial state, the threaded cylinder is opposite to one of the through holes 23;

[0094] The bottom of the collecting cylinder 6 is provided with a second pipe joint 61, and the second pipe joint 61 is communicated with an external dust collector;

[0095] In the implementation, when the first cylinder 38 drives the cylindrical block 31 to move upward to the initial position, the second cylinder 52 is controlled to be elongated, the elongated second cylinder 52 drives the second arc-shaped plate 51 to move, the moving second arc-shaped plate 51 gradually extends into the first vertical cylinder 3, and gradually passes below the filter cylinder 32 and is attached to the bottom surface of the cylindrical block 31 and the filter cylinder 32, in the process, the cylindrical block 31 and the bottom surface of the filter cylinder 32 can be scraped, so that the fly ash remaining on the bottom of the cylindrical block 31 and the bottom of the filter cylinder 32 is pushed out and gradually pushed into the collecting bin 53, when the second arc-shaped plate 51 gradually approaches the collecting bin 53, the second arc-shaped plate 51 gradually passes through the arc-shaped groove 5 close to the collecting bin 53 and pushes the fly ash into the collecting bin 53, and then the second cylinder 52 is controlled to return to the initial state;

[0096] Specifically, since the collecting cylinder 6 is arranged near one side of the smoke pipe 11, when the through hole 23 treated by the treatment mechanism rotates above the collecting cylinder 6, the fly ash remaining in the through hole 23 falls into the collecting cylinder 6, and the second pipe joint 61 is communicated with the external dust collector, so that the fly ash and gas in the collecting cylinder 6 and the through hole 23 can be sucked through the second pipe joint 61, thereby avoiding the fly ash remaining in the through hole 23.

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

[0098] The third cylinder 71 is arranged on the second vertical cylinder 7, and the third cylinder 71 is provided with a push block 72 at the bottom;

[0099] In the embodiment, the bottom of the round plate 21 is fixedly connected with a driving shaft 73;
