Description

Technical Field

[0001] This application relates to the field of waste incineration power generation technology, and in particular to a waste incineration power generation device. Background Technology

[0002] Waste disposal is a crucial aspect of urban environmental governance, and waste-to-energy incineration technology has become an important development direction in the environmental protection field. Compared to traditional waste incineration methods, waste-to-energy incineration not only avoids secondary pollution but also converts waste into electricity, achieving resource reuse.

[0003] One type of waste-to-energy incineration device consists of a boiler, belt conveyor, steam turbine, generator, and flue gas treatment system. When waste needs to be incinerated for power generation, the waste is placed on the belt conveyor and started. The belt conveyor drives the waste into the boiler for combustion. After the waste is burned, water is converted into high-temperature and high-pressure steam. The high-pressure steam drives the steam turbine to rotate, and the steam turbine drives the generator to generate electricity. At the same time, the flue gas treatment system purifies the emitted flue gas to ensure environmental standards and achieve efficient resource conversion.

[0004] During the process of using the above-mentioned waste incineration power generation equipment to process waste, some waste not only cannot be fully burned, but also some waste has no calorific value, resulting in low waste incineration efficiency and consequently low power generation efficiency. Utility Model Content

[0005] In order to improve the combustion efficiency of waste during incineration, this application provides a waste incineration power generation device.

[0006] This application provides a waste-to-energy incineration device, which adopts the following technical solution:

[0007] A waste-to-energy incineration device, comprising:

[0008] A crushing component, which is fixedly installed on the ground, can convert solid waste into powder.

[0009] A screening component is rotatably positioned directly below the crushing component, which can effectively separate metal impurities from powdery waste.

[0010] A conveyor belt, which is rotatably positioned directly below the screening component;

[0011] An incinerator is fixedly installed on the ground. A feed inlet is fixedly installed on one side of the incinerator. One end of the conveyor belt extends into the feed inlet. A slag discharge pipe is fixedly installed on the side of the incinerator adjacent to the feed inlet.

[0012] An air intake fan is fixedly installed on one side of the incinerator, and the air intake fan is fixedly connected to the bottom of the incinerator through an air intake pipe;

[0013] A steam turbine, which is fixedly installed on the ground and located on one side of the incinerator, is connected to the incinerator via a steam pipe;

[0014] A generator is fixedly installed on the ground and located directly in front of the steam turbine.

[0015] By adopting the above technical solution, when waste-to-energy incineration is needed, the waste is left to stand for a period of time, allowing moisture to evaporate and increasing its calorific value. The dried waste is then placed in a crushing unit, which is activated. Once activated, the crushing unit transforms the solid waste into powder. The powder falls into a screening unit under its own weight, which is activated to effectively separate large metal particles. The pure powder falls onto a conveyor belt, which is activated to transport the powder to the incinerator. Simultaneously, the air intake fan is activated, allowing the powder to be fully combusted upon entering the incinerator. The heat released from the combustion converts water into high-temperature, high-pressure steam. This steam enters the turbine through steam pipes and drives it to rotate at high speed. The turbine's rotation cuts the magnetic field lines within the generator, thus generating an electric current. This method effectively transforms lumpy waste into powder, significantly increasing the contact area between the waste and oxygen, thereby improving the efficiency of waste combustion.

[0016] Optionally, the crushing component includes:

[0017] A broken outer shell, which is fixedly installed on the ground;

[0018] A feed hopper is fixedly disposed on the top of the crushing shell and is in communication with the crushing shell;

[0019] Two first motors are arranged at intervals along the crushing shell. Both first motors are fixedly arranged on one side of the crushing shell and are on the same horizontal line.

[0020] The crushing rollers are arranged in a one-to-one correspondence with the first motor. Each crushing roller is rotatably disposed inside the crushing housing, and each crushing roller is fixedly connected to the output shaft of the corresponding first motor.

[0021] By adopting the above technical solution, when waste needs to be incinerated for power generation, the waste is fed into the crushing shell through the feed hopper. The first motor is then started, driving the crushing rollers to rotate. The rotating rollers squeeze and crush the non-metallic waste inside the crushing shell, transforming it from a solid state into powder. Metallic waste, due to its higher density, cannot be crushed by the rollers and remains solid after passing through the crushing shell. This method of crushing non-metallic waste effectively increases the contact area between the waste and air during combustion, thereby improving the combustion efficiency.

[0022] Optionally, the screening element includes:

[0023] A rotating frame is fixedly installed on the ground and located directly below the broken shell.

[0024] The second motor is provided in two at intervals along the rotating frame. Both second motors are fixedly installed on one side of the rotating frame and are on the same horizontal line.

[0025] A rotating shaft is provided, which is arranged one-to-one with the second motor. Each rotating shaft is rotatably mounted on the rotating frame, and each rotating shaft is fixedly connected to the output shaft of the corresponding second motor.

[0026] The rollers are provided in two sets. Each rotating shaft is fixedly provided with one set of rollers. Each set of rollers includes two rollers, and the two rollers are fixedly sleeved on the outer periphery of the corresponding rotating shaft.

[0027] A rotary drum screen is rotatably mounted above a rotating frame, with each roller contacting the outer wall of the rotary drum screen.

[0028] By adopting the above technical solution, after non-metallic and metallic waste are crushed by the crushing rollers, the powdery non-metallic waste and solid metallic waste fall into the drum screen under the action of gravity. The second motor is then started, driving the rotating shaft, which in turn drives the rollers. Because the drum screen is in contact with the rollers, the drum screen begins to rotate under the action of friction after the rollers rotate. As the drum screen rotates, the powdery non-metallic waste falls through the screen holes onto the conveyor belt, while the solid metallic waste is discharged from one end of the drum. This screening method effectively separates non-metallic and metallic waste, ensuring that only non-metallic waste enters the incinerator, preventing metallic waste with no calorific value from entering, and thus effectively improving the thermal efficiency of the incinerator when burning waste.

[0029] Optionally, the drum screen is a permanent magnet drum screen.

[0030] By adopting the above technical solution, when powdered non-metallic waste and solid metallic waste enter the drum screen, the second motor is started. The second motor drives the rotating shaft and rollers to rotate synchronously. The rotation of the rollers drives the drum screen to rotate. As the drum screen rotates, the powdered non-metallic waste passes through the screen holes and falls onto the conveyor belt, while the solid metallic waste is discharged from one end of the drum screen. During the rotation of the drum screen, some fine metallic waste may fall through the screen holes onto the conveyor belt. At this time, the permanent magnet drum screen can adsorb the fine metallic waste onto the inner wall of the drum screen, preventing it from mixing with the non-metallic waste. The permanent magnet drum screen effectively improves the screening accuracy when separating non-metallic and metallic waste.

[0031] Optionally, a limiting plate is fixedly provided on the outer periphery of the drum screen, and each roller is in contact with the limiting plate.

[0032] By adopting the above technical solution, after powdered non-metallic waste and solid metallic waste fall into the drum screen, the second motor is activated. The rotation of the second motor drives the rotating shaft and rollers to rotate, which in turn drives the drum screen to rotate. During the rotation of the drum screen driven by the rollers, the setting of the limiting plate ensures that the drum screen will not shift back and forth, thus ensuring that the drum screen maintains a stable rotation trajectory. The setting of the limiting plate effectively improves the stability of the drum screen during rotation.

[0033] Optionally, a cyclone separator is fixedly installed on the side of the incinerator away from the feed inlet, and the cyclone separator is connected to the incinerator through a flue gas pipe.

[0034] By adopting the above technical solution, when powdered non-metallic waste enters the incinerator for combustion, the burned non-metallic waste will be converted into waste gas and residue. The waste gas enters the cyclone separator through the flue gas pipe. Since the waste gas contains some unburned large particles, when the flue gas passes through the cyclone separator, the large particles are returned to the incinerator for secondary combustion under the action of the cyclone separator, ensuring that the combustible large particles in the waste gas can be fully burned, thereby further improving the combustion efficiency when incinerating waste.

[0035] Optionally, an air preheater is fixedly installed at one end of the air inlet pipe near the incinerator.

[0036] By adopting the above technical solution, when the incinerator needs to be started to burn waste, the air intake fan needs to be started to introduce air into the incinerator, thereby ensuring that the incinerator has sufficient oxygen supply when burning waste. The air preheater is set so that the air is preheated before entering the incinerator, thereby increasing the temperature of the air entering the incinerator. The preheated air can accelerate the combustion reaction of waste, thereby effectively improving the efficiency of the incinerator when burning waste.

[0037] Optionally, a gas pipe is fixedly installed on the side of the incinerator near the feed inlet, and the gas pipe is connected to the gas supply system.

[0038] By adopting the above technical solution, when the incinerator is needed to burn waste, the gas supply system is activated, and the gas enters the incinerator through the gas pipe. After entering the incinerator, the gas provides additional combustion aid for the waste, ensuring that the waste can burn continuously and stably during the incineration process, thereby further improving the incineration efficiency of the incinerator when burning waste.

[0039] In summary, the present invention provides a waste incineration power generation device, which includes at least one of the following beneficial technical effects:

[0040] 1. When waste-to-energy incineration is needed, the waste is left to stand for a period of time to allow moisture loss and increase its calorific value. The dried waste is then placed in a crushing unit, which is activated to convert the solid waste into powder. The powder falls into a screening unit under its own weight, which is activated to effectively separate large metal particles. The purified powder then falls onto a conveyor belt, which is activated to transport the powder to the incinerator. Simultaneously, the air intake fan is activated, allowing the powder to be fully combusted upon entering the incinerator. The heat released from the combustion converts water into high-temperature, high-pressure steam. This steam enters the turbine through steam pipes and drives it to rotate at high speed. The turbine's rotation cuts the magnetic field lines within the generator, generating an electric current. This process of converting lumpy waste into powder effectively increases the contact area between the waste and oxygen, thereby improving the efficiency of waste combustion.

[0041] 2. When waste needs to be incinerated for power generation, the waste is fed into the crushing shell through the feed hopper. The first motor is started, which drives the crushing rollers to rotate. The rotating rollers squeeze and crush the non-metallic waste inside the crushing shell, transforming it from a solid state into powder. Metallic waste, due to its higher density, cannot be crushed by the rollers and remains solid after passing through the crushing shell. This method of crushing non-metallic waste effectively increases the contact area between the waste and air during combustion, thereby improving the combustion efficiency.

[0042] 3. After being crushed by the crushing rollers, the powdered non-metallic waste and the solid metal waste fall into the drum screen under gravity. The second motor is then activated, driving the rotating shaft, which in turn drives the rollers. Because the drum screen is in contact with the rollers, the drum screen rotates due to friction. As the drum screen rotates, the powdered non-metallic waste falls through the screen holes onto the conveyor belt, while the solid metal waste is discharged from one end of the drum. This screening method effectively separates non-metallic and metal waste, ensuring that only non-metallic waste enters the incinerator and preventing non-calorific metal waste from entering, thereby effectively improving the thermal efficiency of the incinerator.

[0049] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0050] Combination Figure 1 and Figure 2 This application discloses a waste incineration power generation device, including a crushing component 2, a screening component 3, a conveyor belt 16, an incinerator 1, an air intake fan 6, a steam turbine 12, and a generator 14. The crushing component 2 is fixedly installed on the ground and can convert solid waste into powder. The screening component 3 is rotatably installed directly below the crushing component 2 and can effectively separate metal impurities in the powdered waste. The conveyor belt 16 is rotatably installed directly below the screening component 3. The incinerator 1 is fixedly installed on the ground, with one side of the incinerator 1 fixedly installed... A feed inlet is fixedly provided, and one end of the conveyor belt 16 extends into the feed inlet. A slag discharge pipe 11 is fixedly provided on the side of the incinerator 1 adjacent to the feed inlet. An air intake fan 6 is fixedly provided on one side of the incinerator 1 and is fixedly connected to the bottom of the incinerator 1 through an air intake pipe 62. A steam turbine 12 is fixedly provided on the ground and is located on one side of the incinerator 1. The steam turbine 12 is connected to the incinerator 1 through a steam pipe 13. A generator 14 is fixedly provided on the ground and is located directly in front of the steam turbine 12.

[0051] In this embodiment, the crusher 2 is fixed to the ground by bolts, the conveyor belt 16 is fixed to the ground by bolts, the incinerator 1 is fixed to the ground by bolts, the air intake fan 6 is fixed to the ground by bolts, and the air intake pipe 62 is integrally formed and fixedly connected to the incinerator 1 and the air intake fan 6. The ash discharge pipe 11 can be integrally formed and fixedly connected to the incinerator 1, or it can be connected by welding; no specific limitation is made in this embodiment. The steam turbine 12 is fixed to the ground by bolts, the steam pipe 13 is integrally formed and fixedly connected to the incinerator 1 and the steam turbine 12, and the generator 14 is fixed to the ground by bolts.

[0052] In practical use, when it is necessary to incinerate waste for power generation, the waste that has been left for a period of time is fed into the crushing unit 2. The crushing unit 2 is then activated, and it breaks down solid non-metallic waste into powder, while the metallic waste remains solid and cannot be crushed. After passing through the crushing unit 2, the non-metallic waste becomes powder and the metallic waste becomes solid. Under their own gravity, the powdered non-metallic waste and the solid metallic waste fall simultaneously into the screening unit 3. The screening unit 3 is then activated, and the powdered non-metallic waste passes through it and falls onto the conveyor belt 16, while the solid metallic waste is discharged from one side of the screening unit 3. After the powdered non-metallic waste falls onto the conveyor belt 16, the conveyor belt 16 is started. Once started, the powdered non-metallic waste is fed into the incinerator 1 through the feed inlet. Simultaneously, the air intake fan 6 is started, which delivers air into the incinerator 1. After entering the incinerator 1, the powdered non-metallic waste mixes thoroughly with the air and burns rapidly, converting the moisture in the incinerator 1 into high-temperature, high-pressure steam. The steam is then transported to the steam turbine 12 through the steam pipe 13. Driven by the steam, the steam turbine 12 rotates at high speed. After the steam turbine 12 rotates, it cuts the magnetic field lines in the generator 14, thereby causing the generator 14 to generate current, thus achieving the purpose of generating electricity by incinerating waste.

[0053] Combination Figure 1 , Figure 2 and Figure 3In a specific embodiment, the crushing component 2 includes a crushing shell 21, a feeding hopper 22, a first motor 23, and a crushing roller 24. The crushing shell 21 is fixedly installed on the ground, and the feeding hopper 22 is fixedly installed on the top of the crushing shell 21 and is connected to the crushing shell 21. Two first motors 23 are arranged at intervals along the crushing shell 21. Both first motors 23 are fixedly installed on one side of the crushing shell 21 and are on the same horizontal line. The crushing rollers 24 are arranged in a one-to-one correspondence with the first motors 23. Each crushing roller 24 is rotatably installed inside the crushing shell 21 and is fixedly connected to the output shaft of the corresponding first motor 23. The screening component 3 includes a rotating frame 31, a second motor 32, a rotating shaft 33, rollers 34, and a drum screen 35. The rotating frame 31 is fixedly installed on the ground and located directly below the crushing shell 21. Two second motors 32 are spaced apart along the rotating frame 31, each fixedly installed on one side of the rotating frame 31 and on the same horizontal line. A rotating shaft 33 corresponds one-to-one with each second motor 32, each rotating shaft 33 rotatably mounted on the rotating frame 31 and fixedly connected to the output shaft of the corresponding second motor 32. Two sets of rollers 34 are provided, with one set of rollers 34 fixedly mounted on each rotating shaft 33. Each set of rollers 34 contains two rollers 34, both fixedly fitted onto the outer periphery of the corresponding rotating shaft 33. The drum screen 35 is rotatably mounted above the rotating frame 31, with each roller 34 in contact with the outer wall of the drum screen 35. The drum screen 35 is a permanent magnet drum screen 35. A limiting plate 4 is fixedly installed on the outer periphery of the drum screen 35, and each roller 34 is in contact with the limiting plate 4.

[0054] In this embodiment, the crushing shell 21 has a rectangular structure and is fixed to the ground by bolts. The feed hopper 22 can be integrally formed and fixedly connected to the crushing shell 21, or it can be connected by welding; no specific limitation is made in this embodiment. The first motor 23 is fixedly connected to the crushing shell 21 by bolts, and the crushing roller 24 is fixedly connected to the output shaft of the first motor 23 by welding. The rotating frame 31 is fixedly set to the ground by bolts, and the second motor 32 is fixedly connected to the rotating frame 31 by bolts. The rotating shaft 33 is fixedly connected to the output shaft of the second motor 32 by welding. The roller 34 can be integrally formed and fixedly connected to the rotating shaft 33, or it can be connected by welding; no specific limitation is made in this embodiment. The drum screen 35 has a cylindrical structure, and multiple screen holes are spaced apart on the outer periphery of the drum screen 35. The limiting plate 4 can be integrally formed and fixedly connected to the drum screen 35, or it can be connected by welding; no specific limitation is made in this embodiment.

[0055] In practical use, when the incinerator 1 is used to burn waste for power generation, the waste is left to stand for a period of time to allow the moisture in the waste to evaporate and the waste to become dry. The dry waste is then fed into the crushing shell 21 through the feed hopper 22. The first motor 23 is started, and after the first motor 23 starts, it drives the crushing roller 24 to rotate. The waste contains both metal and non-metal waste. Since the non-metal waste has a lower hardness, it is crushed into powder by the crushing roller 24 after it rotates, while the harder metal waste is squeezed into small pieces by the crushing roller 24. Non-metallic waste in powder form and small pieces of metallic waste fall into the drum screen 35 under their own gravity. The second motor 32 is then activated, driving the rotating shaft 33 to rotate. The rotating shaft 33 then drives the roller 34 to rotate within the limiting plate 4. Since the roller 34 is in contact with the outer wall of the drum screen 35, its rotation drives the drum screen 35 to rotate. Because the roller 34 rotates within the limiting plate 4, the drum screen 35 will not shift back and forth after being driven to rotate. Multiple screen holes are fixedly provided on the outer periphery of the drum screen 35. After the drum screen 35 rotates, the powdery non-metallic waste falls through the screen holes onto the conveyor belt 16, while the large-diameter large pieces of metallic waste cannot pass through the screen holes. Therefore, after the drum screen 35 rotates, the large-diameter large-piece metallic waste is discharged through one end of the drum screen 35. During the rotation of the drum screen 35, which is a permanent magnet drum screen 35, the drum screen 35 can adsorb smaller diameter metal waste onto the inner wall of the drum screen 35 after rotation, thereby further ensuring that smaller non-metallic waste will not fall onto the conveyor belt 16, thus ensuring the purity of the waste when the incinerator 1 incinerates the waste.

[0056] Combination Figure 1 In a specific embodiment, a cyclone separator 51 is fixedly installed on the side of the incinerator 1 away from the feed inlet, and the cyclone separator 51 is connected to the incinerator 1 through a flue gas pipe 5. An air preheater 61 is fixedly installed at the end of the air inlet pipe 62 near the incinerator 1. A gas pipe 15 is fixedly installed on the side of the incinerator 1 near the feed inlet, and the gas pipe 15 is connected to the gas supply system.

[0057] In this embodiment, the flue gas pipe 5 is integrally formed and fixedly connected to the incinerator 1 and the cyclone separator 51. The air preheater 61 can be fixedly connected to the air inlet pipe 62 and the incinerator 1 by welding or by bolting; no specific limitation is made in this embodiment. The gas pipe 15 is integrally formed and fixedly connected to the incinerator 1.

[0058] In practical use, when powdered waste enters incinerator 1, the intake fan 6 and air preheater 61 are started. After the intake fan 6 starts, air enters incinerator 1 through intake pipe 62 and air preheater 61. After being heated by air preheater 61, the air enters incinerator 1 at a higher temperature. After the high-temperature air enters incinerator 1, the gas generator is started. The gas generated by the gas generator enters incinerator 1 through gas pipe 15. At this time, incinerator 1 contains high-temperature air, gas, and powdered waste. The ignition device is then activated, instantly igniting the mixed gas. The powdered waste burns rapidly under the high temperature. After the powdered waste burns, water is converted into high-temperature, high-pressure steam. The steam enters turbine 12 through steam pipe 13 and drives turbine 12 to rotate. After turbine 12 rotates, it cuts the magnetic field lines in generator 14, thereby causing generator 14 to generate current.

[0059] After combustion, the powdered waste is converted into residue and exhaust gas. The residue is discharged through the slag discharge pipe 11, while the exhaust gas enters the cyclone separator 51 through the flue gas pipe 5. Since the exhaust gas contains some large particles that are not completely burned, the unburned large particles are separated by the cyclone separator 51 and re-enter the incinerator 1 through the flue gas pipe 5 for secondary combustion. This ensures that the unburned large particles in the exhaust gas are completely burned, thereby improving the waste incineration efficiency.

[0060] The principle of this embodiment is as follows: When waste needs to be incinerated for power generation, the waste that has been left for a period of time is fed into the crushing component 2. The crushing component 2 is activated, and after activation, the solid non-metallic waste is crushed into powder, while the metallic waste cannot be crushed and remains solid. After passing through the crushing component 2, the non-metallic waste and the metallic waste become powder and solid, respectively. Under their own gravity, the powder and solid non-metallic waste fall simultaneously into the screening component 3. The screening component 3 is activated, and after activation, the powdery non-metallic waste falls onto the conveyor belt 16 through the screening component 3, while the solid metallic waste is discharged from one side of the screening component 3. After the powdered non-metallic waste falls onto the conveyor belt 16, the conveyor belt 16 is started. Once started, the powdered non-metallic waste is fed into the incinerator 1 through the feed inlet. Simultaneously, the air intake fan 6 is started, which delivers air into the incinerator 1. After entering the incinerator 1, the powdered non-metallic waste mixes thoroughly with the air and burns rapidly, converting the moisture in the incinerator 1 into high-temperature, high-pressure steam. The steam is then transported to the steam turbine 12 through the steam pipe 13. Driven by the steam, the steam turbine 12 rotates at high speed. After the steam turbine 12 rotates, it cuts the magnetic field lines in the generator 14, thereby causing the generator 14 to generate current, thus achieving the purpose of generating electricity by incinerating waste.

[0061] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
