[0001] This invention relates to the field of waste heat power generation technology in solid waste treatment, specifically to a waste heat power generation device for solid waste treatment. Background Technology
[0002] Solid waste treatment, also known as solid waste disposal, generally refers to the process of transforming solid waste into a form suitable for transportation, storage, utilization, or disposal using physical, chemical, biological, physicochemical, and biochemical methods. The goals of solid waste treatment are harmlessness, volume reduction, and resource recovery. Simultaneously, solid waste treatment is often connected to power generation facilities so that the heat generated during treatment can be used for electricity generation.
[0003] Existing solid waste treatment power generation devices, such as Chinese patent application CN113898950A, involve crushing, filtering, and pulverizing solid waste. The included crusher and blade shaft thoroughly crush the solids, eliminating the need for manual labor and saving labor costs. Simultaneously, this invention can also incinerate the waste for thermal power generation. The included steam generator converts the heat energy generated from waste combustion into steam kinetic energy, preventing resource waste. The included dual air absorption mechanism purifies the harmful gases produced during combustion, preventing them from entering the atmosphere. Furthermore, the included relay disk allows for the selection and recovery of certain metals after the solid waste is crushed, preventing the waste of metal resources and facilitating their subsequent reuse.
[0004] However, the following problems still exist: when the waste heat generated after solid waste treatment is used for power generation, the amount of steam replaced by the waste heat is small, which cannot effectively drive the steam impeller to rotate, resulting in a low utilization rate of waste heat. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a waste heat power generation device for solid waste treatment, which has the advantages of continuously and effectively utilizing the waste heat after solid waste treatment to generate electricity, improving the utilization rate of waste heat after solid waste treatment, and solving the problem that when the waste heat generated after solid waste treatment is used for power generation, the amount of steam replaced by the waste heat is small, which cannot effectively drive the steam impeller to rotate, resulting in a low utilization rate of waste heat.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a waste heat power generation device for solid waste treatment, comprising a body, a solid waste treatment mechanism disposed within the body, and a waste heat power generation mechanism disposed beside the body. The solid waste treatment mechanism includes a feed pipe and an incinerator. The feed pipe is fixedly installed on the top of the side wall of the body and communicates with the body. The incinerator is fixedly installed at the bottom of the body and is located below the feed pipe. The cross-sectional area of the incinerator is the same as the cross-sectional area inside the body. Gas is intermittently input into the incinerator to burn the solid waste fed into the body from the feed pipe. When the feed pipe transports solid waste into the body, the gas input into the incinerator is disconnected.

The size of the opening of the blocking ball is the same as the internal cross-sectional size of the gas pipe. The gas pipes on both sides of the protective cylinder will only be connected when the opening of the blocking ball coincides with the internal passage of the gas pipe. A first bevel gear is rotatably fitted on the protective cylinder, and the first bevel gear is poweredly connected to the blocking ball. A gear is rotatably fitted on the machine body, and the bottom end of the gear meshes with the first bevel gear. A second bevel gear is rotatably fitted on the feed pipe, and the second bevel gear is poweredly connected to the partition plate. The second bevel gear meshes with the top end of the gear.
[0011] Preferably, the waste heat power generation mechanism further includes an exhaust pipe, which is fixedly installed at the top of the machine body. One end of the exhaust pipe is connected to the machine body, and the other end of the exhaust pipe is fixedly connected to the bottom of the steam box. A heat exchange tube is fixedly installed at the bottom of the steam box, and the bottom end of the heat exchange tube is connected to the other end of the exhaust pipe. The top end of the heat exchange tube penetrates the side wall of the steam box and extends to the outside of the steam box. An air supply pipe is fixedly installed at the top of the steam box, with one end connected to the steam box and the other end connected to the working cylinder.
[0012] Preferably, the interior of the working cylinder is divided into multiple regions by the fan blades. When the fan blades are not rotating, the region adjacent to the air supply pipe is the first receiving chamber, which is located on one side of the working cylinder.

[0014] Compared with the prior art, the present invention provides a waste heat power generation device for solid waste treatment, which has the following beneficial effects:
[0015] 1. In this waste heat power generation device for solid waste treatment, when steam flows into the working cylinder and is between the blades of two adjacent fan blades, the air pressure increases with the increase of steam, causing the air pressure to drive the fan blades to rotate. When the steam is between the two adjacent blades of the last fan blade, the steam will be discharged from the working cylinder, so that the air pressure between the two adjacent blades of the last fan blade is always lower than the air pressure of the other positions, thus causing the fan blades to rotate continuously, thereby driving the fan blades to drive the generator to generate electricity. This allows the waste heat power generation device to continuously and effectively utilize the waste heat after solid waste treatment to generate electricity, thereby improving the utilization rate of waste heat after solid waste treatment.
[0016] 2. The waste heat power generation device for solid waste treatment, through the setting of partition plates, detectors, and barrier balls, ensures that when the partition plates do not block the feed pipe, the barrier balls will block the gas pipe, thereby reducing the flame of the solid waste burning on the incinerator and preventing the flame from burning the solid waste fuel falling into the machine body in the feed pipe, thus preventing the solid waste in the feed pipe from being ignited, improving the safety and stability of the waste heat power generation device.
[0017] 3. The waste heat power generation device for solid waste treatment rotates by the fan blades abutting the limiting component in the receiving tank, causing the limiting component to rotate into the receiving tank. After the fan blades rotate away, the torsion spring drives the limiting component to reset. When the fan blades rotate in the opposite direction, the limiting component will be limited by the side wall of the receiving tank and will not be able to rotate, thus preventing the fan blades from rotating. This ensures that the fan blades rotate in one direction and improves the stability of the waste heat power generation device. Attached Figure Description

Detailed Implementation
[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a waste heat power generation device for solid waste treatment.
[0033] In one typical implementation of this application, such as Figure 1-12 As shown, a waste heat power generation device for solid waste treatment includes a body 1, a solid waste treatment mechanism 2 installed inside the body 1, and a waste heat power generation mechanism 3 installed beside the body 1. The solid waste treatment mechanism 2 includes a feed pipe 21 and an incinerator 25. The feed pipe 21 is fixedly installed on the top of the side wall of the body 1 and communicates with the inside of the body 1. The incinerator 25 is fixedly installed at the bottom of the inside of the body 1 and is located below the feed pipe 21. The cross-sectional area of the incinerator 25 is the same as the cross-sectional area inside the body 1. Gas is intermittently input into the incinerator 25 to burn the solid waste sent into the body 1 from the feed pipe 21. When the feed pipe 21 is transporting solid waste into the body 1, the gas input into the incinerator 25 is disconnected. When the feed pipe 21 is disconnected from the inside of the body 1, the gas is continuously input into the incinerator 25.
[0034] The waste heat power generation mechanism 3 includes a steam box 32, a working cylinder 35, and fan blades 36. The steam box 32 is fixedly installed next to the machine body 1, and the working cylinder 35 is fixedly installed next to the steam box 32. The fan blades 36 are rotatably fitted inside the working cylinder 35. The fan blades 36 are adapted to the interior of the working cylinder 35. The fan blades 36 have a multi-blade structure, and the fan blades of the fan blades 36 are evenly distributed in a circular shape. The fan blades 36 rotate unidirectionally inside the working cylinder 35. After the waste gas carrying heat in the machine body 1 is introduced into the steam box 32 and exchanges heat with water, the steam in the steam box 32 will flow into the working cylinder 35 and be located between two adjacent fan blades of the fan blades 36. The air pressure drives the fan blades 36 to rotate, and the steam will flow between two adjacent fan blades of the next fan blade 36. When the steam is between two adjacent fan blades of the last fan blade 36, it will be discharged from the working cylinder 35, so that the rotation of the fan blades 36 drives the generator to generate electricity.
[0035] When using this invention:
[0036] Combustible solid waste is fed into the machine body 1 through the feed pipe 21. Once a certain amount of solid waste accumulates in the machine body 1, the feed pipe 21 is disconnected to prevent further entry. At this time, gas is supplied to the incinerator 25, activating it to incinerate the solid waste in the machine body 1. When replenishment is needed, the feed pipe 21 is reopened, and the gas supply to the incinerator 25 is cut off, allowing solid waste to continue entering the machine body 1. Then, the feed pipe 21 is disconnected again, and gas continues to be supplied to the incinerator 25 for incineration. The heat-carrying exhaust gas from incineration is then introduced into the steam box 32 to exchange heat with water, causing the water in the steam box 32 to evaporate and generate steam. Water in the steam tank 32 continuously evaporates, and the steam flows into the working cylinder 35, where it is located between the blades of two adjacent fan blades 36. As the amount of steam increases, the air pressure rises accordingly. However, the pressure between the blades of fan blade 36 is unbalanced, and since fan blade 36 rotates in one direction, the air pressure drives fan blade 36 to rotate. Then, the steam flows into the space between the two adjacent blades of the next fan blade 36, causing fan blade 36 to rotate. When the steam is between the two adjacent blades of the last fan blade 36, the steam is discharged from the working cylinder 35, ensuring that the air pressure between the two adjacent blades of the last fan blade 36 is always lower than the air pressure at the other positions. This causes fan blade 36 to rotate continuously, driving the generator to generate electricity.
[0037] As steam flows into the working cylinder 35 and is positioned between the blades of two adjacent fan blades 36, the air pressure increases with the amount of steam, causing the fan blades 36 to rotate. When the steam is positioned between the two adjacent blades of the last fan blade 36, the steam will be discharged from the working cylinder 35, ensuring that the air pressure between the two adjacent blades of the last fan blade 36 is always lower than the air pressure at other positions. This causes the fan blades 36 to rotate continuously, driving the generator to generate electricity. This allows the waste heat power generation device to continuously and effectively utilize the waste heat after solid waste treatment to generate electricity, thereby improving the utilization rate of waste heat after solid waste treatment.
[0038] Furthermore, the solid waste treatment mechanism 2 also includes a partition plate 22, which is rotatably fitted inside the feed pipe 21. The size of the partition plate 22 is adapted to the internal cross-section of the feed pipe 21. A rotating arm cylinder 23 is fixedly installed on the feed pipe 21. The shaft of the rotating arm cylinder 23 passes through the wall of the feed pipe 21. The rotating arm cylinder 23 is poweredly connected to the partition plate 22. A detector 24 is fixedly installed on the feed pipe 21. The detection end of the detector 24 passes through the wall of the feed pipe 21. The detector 24 is signal connected to the rotating arm cylinder 23.
[0039] When the partition plate 22 blocks the passage of the feed pipe 21, as solid waste is fed into the feed pipe 21, the solid waste will be blocked by the partition plate 22 and accumulate in the feed pipe 21. When the solid waste accumulates to a certain amount, it will be detected by the detector 24. The detector 24 controls the rotating arm cylinder 23 to run, and the rotating arm cylinder 23 drives the partition plate 22 to rotate, thereby opening the partition plate 22 to block the passage in the feed pipe 21, so that the solid waste can enter the machine body 1.
[0040] Furthermore, a gas pipe 26 is fixedly installed on the side wall of the machine body 1, penetrating the wall of the machine body 1. The gas pipe 26 is located below the incinerator 25, with one end connected to the bottom of the incinerator 25 and the other end connected to the gas delivery system outside the device. An air cylinder 27 is fixedly installed at the bottom inside the machine body 1, with the gas pipe 26 penetrating through it and communicating with it. An intermittent gas delivery roller 28 rotates inside the air cylinder 27, intermittently delivering gas. The roller 28 is adapted to the interior of the air cylinder 27. Multiple passages are opened on the intermittent air delivery roller 28. The passages on the intermittent air delivery roller 28 are evenly distributed in a circle. The passages of each intermittent air delivery roller 28 are interconnected. The intermittent air delivery roller 28 rotates inside the air cylinder 27. The gas pipes 26 on both sides of the air cylinder 27 will only be connected when one passage of the intermittent air delivery roller 28 is connected to the gas pipe 26. A drive motor 29 is fixedly installed at the bottom of the machine body 1. The drive motor 29 is poweredly connected to the intermittent air delivery roller 28.
[0041] The drive motor 29 is started, which drives the intermittent gas delivery roller 28 to rotate inside the gas cylinder 27. This causes the gas pipes 26 on both sides of the gas cylinder 27 to be affected by the passage of the intermittent gas delivery roller 28, so that the passage in the gas pipes 26 is in a state of repeated opening and closing. This allows the gas pipes 26 to intermittently supply gas to the incinerator 25, ensuring that the solid waste in the machine body 1 is continuously incinerated while the use of gas is minimized, thus reducing the operating cost of the waste heat power generation device.
[0042] Furthermore, a protective sleeve 210 is fixedly installed on the gas pipe 26, through which the gas pipe 26 passes, and the gas pipe 26 communicates with the protective sleeve 210. A baffle ball 211 is rotatably fitted inside the protective sleeve 210, fitting snugly against the interior of the protective sleeve 210. The baffle ball 211 has an opening, the size of which is the same as the internal cross-sectional size of the gas pipe 26. When the opening of the baffle ball 211 coincides with the internal passage of the gas pipe 26, it ensures… The gas pipes 26 on both sides of the protective cylinder 210 will then be connected. A first bevel gear 212 is rotatably fitted on the protective cylinder 210. The first bevel gear 212 is poweredly connected to the blocking ball 211. A rack 213 is rotatably fitted on the machine body 1. The bottom end of the rack 213 meshes with the first bevel gear 212. A second bevel gear 214 is rotatably fitted on the feed pipe 21. The second bevel gear 214 is poweredly connected to the partition plate 22. The second bevel gear 214 meshes with the top end of the rack 213.
[0043] As the partition plate 22 rotates, it drives the second bevel gear 214 to rotate, which in turn drives the rack 213 to rotate. The rack 213 then drives the first bevel gear 212 to rotate, which in turn drives the blocking ball 211 to rotate within the protective cylinder 210. This ensures that when the partition plate 22 does not block the passage in the feed pipe 21, the blocking ball 211 does not connect the gas pipes 26 on both sides of the protective cylinder 210. Consequently, the gas pipes 26 do not supply gas to the incinerator 25, ensuring that the flame for incinerating solid waste in the machine body 1 is not too large and preventing the flame from igniting the solid waste in the feed pipe 21.
[0044] Furthermore, the waste heat power generation mechanism 3 also includes an exhaust pipe 31, which is fixedly installed at the top of the body 1. One end of the exhaust pipe 31 is connected to the body 1, and the other end of the exhaust pipe 31 is fixedly connected to the bottom of the steam box 32. A heat exchange pipe 33 is fixedly installed at the bottom of the steam box 32. The bottom end of the heat exchange pipe 33 is connected to the other end of the exhaust pipe 31. The top end of the heat exchange pipe 33 penetrates the side wall of the steam box 32 and extends to the outside of the steam box 32. A gas supply pipe 34 is fixedly installed at the top of the steam box 32. One end of the gas supply pipe 34 is connected to the steam box 32, and the other end of the gas supply pipe 34 is connected to the working cylinder 35.
[0045] As solid waste is incinerated, the heat-carrying exhaust gas enters the heat exchange tube 33 from the exhaust pipe 31, where it exchanges heat with water in the steam box 32, and the generated steam enters the working cylinder 35 through the gas delivery pipe 34.
[0046] Furthermore, the interior of the working cylinder 35 is divided into multiple areas by the fan blades 36. When the fan blades 36 are not rotating, the area adjacent to the air supply pipe 34 is the first receiving chamber 37, which is located on one side inside the working cylinder 35. The other end of the air supply pipe 34 is connected to the first receiving chamber 37. The area adjacent to the first receiving chamber 37 in a clockwise direction is the second receiving chamber 38, which is located at the top of the working cylinder 35. The area adjacent to the second receiving chamber 38 in a clockwise direction is the third receiving chamber 39, which is located on the other side inside the working cylinder 35. The area adjacent to the third receiving chamber 39 in a clockwise direction is the fourth receiving chamber 310, which is located at the bottom of the working cylinder 35.
[0047] The steam entering the working cylinder 35 first enters the first receiving chamber 37. As the steam accumulates, the air pressure drives the fan blade 36 to rotate in the working cylinder 35. Then the steam enters the fourth receiving chamber 310. At this time, the air pressure in the second receiving chamber 38 next to the first receiving chamber 37 is almost equal to that in the fourth receiving chamber 310, so the fan blade 36 stops rotating. As the steam accumulates, the air pressure continues to drive the fan blade 36 to rotate. Then the steam enters the third receiving chamber 39. The steam accumulates in the third receiving chamber 39 to continue driving the fan blade 36 to rotate. Then the steam enters the second receiving chamber 38. At this time, the first receiving chamber 37 is connected to the pressure relief pipe 314, and the steam will be discharged from the pressure relief pipe 314. The steam continues to accumulate in the second receiving chamber 38 to drive the fan blade 36 to rotate, so that the fan blade 36 uses air pressure to form a slow and continuous rotation, so that the fan blade 36 drives the generator to generate electricity.
[0048] Furthermore, a receiving groove 311 is provided on the inner wall of the working cylinder 35. The receiving groove 311 is located in the first receiving chamber 37. A limiting member 312 is rotatably engaged in the receiving groove 311. The top end of the limiting member 312 is located on the rotation path of the fan blade 36. The side wall of the receiving groove 311 on one side of the limiting member 312 restricts the rotation of the limiting member 312, so that the rotation direction of the limiting member 312 is opposite to the rotation direction of the fan blade 36. A torsion spring 313 is sleeved on the shaft of the limiting member 312. One end of the torsion spring 313 is connected to the limiting member 312, and the other end of the torsion spring 313 is connected to the receiving groove 311. A pressure relief pipe 314 is fixedly installed at the bottom end of the working cylinder 35. The pressure relief pipe 314 communicates with the working cylinder 35 and communicates with the fourth receiving chamber 310.
[0049] As the fan blade 36 rotates, it abuts against the limiting member 312 in the receiving groove 311, causing the limiting member 312 to rotate into the receiving groove 311. After the fan blade 36 rotates away, the torsion spring 313 drives the limiting member 312 to reset. When the fan blade 36 rotates in the opposite direction, the limiting member 312 will be limited by the side wall of the receiving groove 311 and will not be able to rotate, thus preventing the fan blade 36 from rotating and ensuring that the fan blade 36 rotates in one direction.
[0050] Working principle:
[0051] Combustible solid waste is fed into the machine body 1 through the feed pipe 21. Once a certain amount of solid waste accumulates in the machine body 1, the feed pipe 21 is disconnected to prevent further entry. At this time, gas is supplied to the incinerator 25, activating it to incinerate the solid waste in the machine body 1. When replenishment is needed, the feed pipe 21 is reopened, and the gas supply to the incinerator 25 is cut off, allowing solid waste to continue entering the machine body 1. Then, the feed pipe 21 is disconnected again, and gas continues to be supplied to the incinerator 25 for incineration. The heat-carrying exhaust gas from incineration is then introduced into the steam box 32 to exchange heat with water, causing the water in the steam box 32 to evaporate and generate steam. Water in the steam tank 32 continuously evaporates, and the steam flows into the working cylinder 35, where it is located between the blades of two adjacent fan blades 36. As the amount of steam increases, the air pressure rises accordingly. However, the pressure between the blades of fan blade 36 is unbalanced, and since fan blade 36 rotates in one direction, the air pressure drives fan blade 36 to rotate. Then, the steam flows into the space between the two adjacent blades of the next fan blade 36, causing fan blade 36 to rotate. When the steam is between the two adjacent blades of the last fan blade 36, the steam is discharged from the working cylinder 35, ensuring that the air pressure between the two adjacent blades of the last fan blade 36 is always lower than the air pressure at the other positions. This causes fan blade 36 to rotate continuously, driving the generator to generate electricity.
[0052] When the partition plate 22 blocks the passage of the feed pipe 21, as solid waste is fed into the feed pipe 21, it will be blocked by the partition plate 22 and accumulate in the feed pipe 21. When the solid waste accumulates to a certain amount, it will be detected by the detector 24. The detector 24 controls the rotating arm cylinder 23 to operate, and the rotating arm cylinder 23 drives the partition plate 22 to rotate, thereby opening the partition plate 22 to block the passage in the feed pipe 21, allowing the solid waste to enter the machine body 1. The drive motor 29 is started, and the drive motor 29 drives the intermittent air delivery roller 28 to rotate in the air cylinder 27, so that the gas pipes 26 on both sides of the air cylinder 27 are affected by the passage of the intermittent air delivery roller 28, so that the passage in the gas pipes 26 is repeatedly opened and closed. The state of the gas pipe 26 intermittently supplies gas to the incinerator 25. As the partition plate 22 rotates, the partition plate 22 drives the second bevel gear 214 to rotate, the second bevel gear 214 drives the rack 213 to rotate, the rack 213 drives the first bevel gear 212 to rotate, and the first bevel gear 212 drives the blocking ball 211 to rotate inside the protective cylinder 210. When the partition plate 22 does not block the passage in the feed pipe 21, the blocking ball 211 does not connect the gas pipes 26 on both sides of the protective cylinder 210. This ensures that the gas pipe 26 does not supply gas to the incinerator 25, ensuring that the flame of the solid waste incineration in the machine body 1 is not too large and preventing the flame from igniting the solid waste in the feed pipe 21.
[0053] As solid waste is incinerated, the heat-carrying exhaust gas enters the heat exchange tube 33 from the exhaust pipe 31, where it exchanges heat with water in the steam box 32. The resulting steam enters the working cylinder 35 through the air supply pipe 34. The steam entering the working cylinder 35 first enters the first receiving chamber 37. As the steam accumulates, the air pressure drives the fan blades 36 to rotate in the working cylinder 35. Then, the steam enters the fourth receiving chamber 310. At this point, the air pressure in the second receiving chamber 38 next to the first receiving chamber 37 and the fourth receiving chamber 310 is almost equal, so the fan... When blade 36 stops rotating, the pressure continues to drive the blade 36 to rotate as steam accumulates. Then the steam enters the third chamber 39, where it accumulates to continue driving the blade 36 to rotate. The steam then enters the second chamber 38. At this time, the first chamber 37 is connected to the pressure relief pipe 314, and the steam will be discharged from the pressure relief pipe 314. The steam continues to accumulate in the second chamber 38 to drive the blade 36 to rotate, thus enabling the blade 36 to use air pressure to form a slow and continuous rotation, so that the blade 36 drives the generator to generate electricity.
[0054] As the fan blade 36 rotates, it abuts against the limiting member 312 in the receiving groove 311, causing the limiting member 312 to rotate into the receiving groove 311. After the fan blade 36 rotates away, the torsion spring 313 drives the limiting member 312 to reset. When the fan blade 36 rotates in the opposite direction, the limiting member 312 will be limited by the side wall of the receiving groove 311 and will not be able to rotate, thus preventing the fan blade 36 from rotating and ensuring that the fan blade 36 rotates in one direction.
[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
