[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] like Figures 1-4 As shown, the solid waste co-incineration and waste heat utilization system of this invention includes: an incinerator 1, a heat exchange component and a power generation component 3.

[0023] The incinerator 1 has a combustion inlet and an exhaust outlet. The combustion inlet is connected to the combustion chamber of the incinerator 1, and the exhaust outlet is used to discharge the flue gas generated by the incinerator 1. The heat exchange assembly includes a heat exchange element located at the exhaust outlet. The heat exchange element has a heat exchange chamber for introducing a heat exchange medium, which exchanges heat with the flue gas discharged from the exhaust outlet. The power generation assembly 3 is connected to the exhaust outlet via a delivery pipe 21. The power generation assembly 3 receives the flue gas discharged from the exhaust outlet and uses the heat absorbed from the flue gas to generate electricity.

[0024] Specifically, such as Figures 1-4As shown, incinerator 1 is used for the incineration of solid waste. Incinerator 1 has an incineration inlet and an exhaust outlet. The incineration inlet is connected to the combustion chamber of incinerator 1, allowing solid waste to be fed into the combustion chamber for incineration. The exhaust outlet is used to discharge the flue gas generated during the incineration process. A heat exchange assembly is located at the exhaust outlet of incinerator 1. The heat exchange assembly has a heat exchange chamber. The design of the heat exchange chamber allows a heat exchange medium (such as water or oil) to pass through it and exchange heat with the hot flue gas discharged from the exhaust outlet. Power generation assembly 3 is connected to the exhaust outlet of incinerator 1 through a delivery pipe 21. This means that the hot flue gas discharged from the exhaust outlet is guided to power generation assembly 3. Power generation assembly 3 uses the heat of this flue gas to generate electricity.

[0025] It is understandable that, such as Figures 1-4 As shown, a partition plate 11 is horizontally fixed at the bottom of the inner cavity of the incinerator 1. The partition plate 11 divides the inner cavity of the incinerator 1 into two parts: the upper part is the combustion chamber and the lower part is the ash collection chamber. A through hole is opened at the center of the partition plate 11, and a regulating valve 12 is embedded in the through hole. The regulating valve 12 is used to control the flow rate of high-temperature gas from the combustion chamber to the ash collection chamber.

[0026] The power generation assembly 3 includes a collection component, a steam generator, a pressure regulating valve 12, and a turbine generator. The collection component is connected to the exhaust port via a delivery pipe 21. The steam generator is connected to the collection component. The pressure regulating valve 12 is fixed to the outer wall of the steam generator by bolts. The turbine generator is connected to the pressure regulating valve 12 via a pipe.

[0027] In other words, during the process of solid waste entering the incinerator 1, flue gas is discharged from the exhaust port and enters the collection component. The steam generator exchanges heat with the flue gas. After the steam generator generates steam, the opening of the pressure regulating valve 12 can be adjusted in real time according to the steam pressure to ensure that the steam pressure is stably input into the turbine generator and improve the power generation efficiency.

[0028] Preferably, the steam generator has a spiral tube to increase the heat exchange area with the flue gas and improve the thermal energy utilization rate.

[0029] Therefore, the solid waste co-incineration and waste heat utilization system of this invention effectively recovers heat from the flue gas generated during incineration through the heat exchange components, and uses this heat to heat the heat exchange medium. Heat energy that would otherwise be directly emitted into the atmosphere is used to preheat the medium required by the power generation component 3, thereby improving the overall thermal energy utilization efficiency of the system. The close connection and coordinated operation between the incinerator 1, the heat exchange components, and the power generation component 3 improves the overall integration of the system. This integrated design simplifies the operation process, reduces energy loss, and makes the system operate more efficiently.

[0030] It should be noted that the flue gas temperature coming out of the combustion chamber is generally around 1000℃. Due to the high temperature of the flue gas, it may damage some of the equipment for subsequent flue gas treatment or reuse. Therefore, the flue gas coming out at this temperature needs to be cooled down to around 600℃ through heat exchange to ensure that the subsequent equipment can operate normally and stably.

[0031] The flue gas coming out at this temperature needs to be cooled down to around 600°C through heat exchange, and the water from the heat exchange can be used for heating. In some embodiments, the solid waste co-incineration and waste heat utilization system of the present invention further includes a feeding assembly 4, which includes a conveying component 41 and a diverting component 42. The conveying component 41 is used to convey materials, and one end of the conveying component 41 is arranged adjacent to the incineration inlet. The diverting component 42 is connected to the incinerator 1, and at least a portion of the diverting component 42 is placed inside the incineration inlet. The diverting component 42 has multiple diverting channels 434, and all multiple diverting channels 434 are connected to the incineration inlet.

[0032] Specifically, such as Figures 1-4 As shown, the conveyor 41 is a device for transporting solid waste from the outside into the incinerator 1. The conveyor 41 can be composed of a conveyor belt, a screw conveyor, or other forms of conveying machinery. One end of the conveyor 41 is arranged near the incineration inlet to facilitate the efficient delivery of solid waste into the combustion chamber of the incinerator 1.

[0033] The diverter 42 is connected to the incinerator 1, and its main function is to evenly distribute the solid waste delivered by the conveyor 41 into the combustion chamber of the incinerator 1. At least a portion of the diverter 42 is placed inside the incineration inlet to ensure that the waste can be evenly distributed in the combustion chamber, thereby improving incineration efficiency.

[0034] In other words, through the diversion component 42, solid waste can be more evenly distributed in the combustion chamber, which helps improve incineration efficiency and reduce incomplete combustion caused by uneven waste distribution. Evenly distributed waste contributes to a stable combustion process, reduces pollutant emissions, and improves incineration quality. The design of the feed assembly 4 allows the system to handle different types and sizes of solid waste, increasing the system's applicability and flexibility.

[0035] In some embodiments, the diverter 42 further includes an adjusting member 43 disposed within the diverter channel 434, at least a portion of which is movable relative to the diverter channel 434 to change the flow rate of the material.

[0036] It is understandable that, such as Figures 1-4As shown, the diversion component 42 is fixed to the top of the incinerator 1 by bolts. Multiple diversion channels 434 are provided inside the diversion component 42, each of which communicates with the combustion chamber of the incinerator 1. An adjustment component 43 is provided inside the diversion component 42, including a baffle 431, a drive rod 432, and a drive motor 433. The baffle 431 is slidably disposed within the diversion channel 434. The drive rod 432 is fixed to the top of the baffle 431, passes through the top of the diversion component 42, and is connected to the output shaft of the drive motor 433. The drive motor 433 is fixed to the top of the diversion component 42 by bolts. Sealing strips are provided on both sides of the baffle 431. The sealing strips are made of high-temperature resistant rubber material and are fixed to both sides of the baffle 431 by adhesive. The drive motor 433 drives the baffle 431 to slide in the diversion channel 434 by rotating the drive rod 432. The change in the position of the baffle 431 can change the opening size of the diversion channel 434, thereby realizing the flow control of different types of solid waste.

[0037] In other words, the regulating component 43 allows the operator to precisely control the flow rate of waste entering the incinerator 1, thereby better controlling the combustion process and improving incineration efficiency. Different types of solid waste have different combustion characteristics. By adjusting the component 43, the system can adapt to different waste characteristics, ensuring efficient incineration under various conditions. The presence of the regulating component 43 increases the system's flexibility, allowing it to be quickly adjusted according to actual needs to adapt to different operating conditions and waste inputs.

[0038] In some embodiments, the heat exchange assembly further includes a circulation component, which includes a heat exchange cylinder 22 that defines a heat exchange chamber. The heat exchange cylinder 22 is fitted onto a delivery pipe 21. The circulation component communicates with the heat exchange chamber to introduce a heat exchange medium into the heat exchange chamber and to recover the heat exchange medium after heat exchange.

[0039] It is understandable that, such as Figures 1-4 As shown, the heat exchange cylinder 22 defines the heat exchange chamber. The heat exchange cylinder 22 is typically made of high-temperature and corrosion-resistant materials, such as stainless steel or alloy materials. The heat exchange cylinder 22 is fitted onto the delivery pipe 21, ensuring that flue gas can enter the heat exchange cylinder 22 through the delivery pipe 21. The circulation component communicates with the heat exchange chamber, and its function is to introduce the heat exchange medium into the heat exchange chamber and recover the heat exchange medium after heat exchange. Optionally, the circulation component includes equipment such as a water pump, heat exchanger, and cooler, which work together to ensure the flow and temperature control of the heat exchange medium.

[0040] In other words, the flue gas generated by incinerator 1 is transported through conveying pipe 21, and the heat exchange medium in heat exchange cylinder 22 located on conveying pipe 21 can exchange heat with the thermal energy in the flue gas. Under the action of the circulation component, the heat exchange medium is sent into the heat exchange chamber to exchange heat with the flue gas. The heat-exchanged medium is recovered and reintroduced into the heat exchange chamber through the circulation component to continue heat exchange. The heat exchange medium after heat exchange can be used for various purposes, such as heating, hot water supply, or driving a turbine generator to generate electricity.

[0041] Therefore, the design of the heat exchange components ensures that the heat energy in the flue gas can be effectively recovered and utilized, improving the overall energy efficiency of the system. The coordinated operation of the circulation components and the heat exchange cylinder 22 ensures the stability of the heat exchange process, making heat recovery more reliable. By adjusting the flow rate and temperature of the heat exchange medium, the system can adapt to different heat demands, improving the system's flexibility and adaptability. The efficient heat exchange process reduces energy waste, helps lower operating costs, and improves economic efficiency.

[0042] In some embodiments, the heat exchanger further includes a turbulence-disrupting component disposed within the heat exchange cavity, the turbulence-disrupting component extending in the same direction as the flow direction of the heat exchange medium.

[0043] Understandably, the turbulence-inducing component can be a blade, a protrusion, or other structure designed to alter the shape of the fluid (heat exchange medium) flow direction. The turbulence-inducing component is placed within the heat exchange chamber, and its extension direction aligns with the flow direction of the heat exchange medium. As the heat exchange medium flows past the turbulence-inducing component, the fluid flow direction is altered, generating eddies and turbulence. This disturbance helps disrupt the fluid boundary layer, making heat transfer between the heat exchange medium and the heat exchange surface more efficient.

[0044] In other words, flow-deflecting components can significantly improve heat exchange efficiency by increasing the disturbance of fluid flow. This is because the disturbance increases the contact area between the fluid and the heat exchange surface, thereby accelerating heat transfer. The design of flow-deflecting components helps optimize the flow pattern of the fluid within the heat exchange chamber, reducing dead zones and stagnation areas, making the entire heat exchange process more uniform and efficient. Of course, flow-deflecting components can be designed to meet different heat exchange requirements, adapting to different fluid types and temperature conditions.

[0045] In some embodiments, the spoiler component includes a spoiler 24 having a plurality of spoiler holes.

[0046] It is understandable that, such as Figures 1-4As shown, the baffle 24 is typically made of metal or other high-temperature resistant materials and is installed inside the heat exchange cavity. The baffle 24 is designed to change the flow direction of the heat exchange medium and increase the contact area between the fluid and the heat exchange surface. Multiple turbulence holes are formed on the baffle 24; the shape and distribution of these holes can be designed according to specific application requirements. The function of the turbulence holes is to generate local eddies during fluid flow, further increasing the degree of fluid turbulence.

[0047] In other words, the design of the baffle 24 and the baffle holes effectively enhances the turbulent flow of the heat exchange medium within the heat exchange cavity. Turbulent flow helps disrupt the fluid boundary layer, increasing the contact area between the fluid and the heat exchange surface, thereby improving heat transfer efficiency. The local eddies generated by the baffle holes promote heat exchange between the heat exchange medium and the heat exchange surface, allowing heat energy to be transferred to the heat exchange medium more quickly. Due to the improved heat transfer efficiency, the system can achieve higher heat recovery efficiency with lower energy consumption, thus reducing overall operating costs. Of course, the design of the baffle 24 and the baffle holes can be adjusted according to different fluid characteristics and heat exchange requirements to adapt to different application scenarios.

[0048] In some embodiments, the heat exchanger further includes heat sinks 23, which are sleeved on the heat exchange cylinder 22. There are multiple heat sinks 23, which are arranged at intervals along the extension direction of the heat exchange cylinder 22.

[0049] Understandably, the heat sink 23 can be a thin plate made of metal or other high-temperature resistant materials. The heat sink 23 has a large surface area to increase the contact area with the heat exchange medium. The heat sink 23 is fitted onto the outside of the heat exchange cylinder 22 and spaced apart along the extension direction of the heat exchange cylinder 22. The design of the heat sink 23 significantly increases the contact area with the heat exchange medium, allowing more heat energy to be transferred from the flue gas to the heat exchange medium. By increasing the heat exchange area, the heat sink 23 can improve heat transfer efficiency, enabling the heat exchange medium to absorb heat energy from the flue gas more quickly.

[0050] In some embodiments, the circulation component includes a circulation conveying component 25 and a circulation collecting component (not shown in the figure). The circulation conveying component 25 is connected to the inlet of the heat exchange cylinder 22, and the circulation collecting component is connected to the outlet of the heat exchange cylinder 22. The circulation collecting component also includes a circulation outlet, which is connected to the power generation component 3.

[0051] Understandably, the circulation conveying component 25 is connected to the inlet of the heat exchanger 22, and its function is to transport the heat exchange medium from the circulation collection component back to the inlet of the heat exchanger 22. The circulation conveying component 25 may include a water pump or other type of conveying equipment to provide sufficient pressure and flow rate so that the heat exchange medium can circulate in the system.

[0052] The circulation collection component is connected to the outlet of the heat exchange cylinder 22, and it is responsible for collecting the heat exchange medium after it has passed through the heat exchange cylinder 22. The circulation collection component also includes a circulation outlet, which is connected to the power generation component 3, so that the heat exchange medium can be sent into the power generation component 3 for energy conversion.

[0053] In other words, under the action of the circulation conveying component 25, the heat exchange medium is transported from the circulation collecting component back to the inlet of the heat exchange cylinder 22. In this way, the heat exchange medium can continuously circulate within the heat exchange cylinder 22, exchanging heat with the flue gas. After passing through the heat exchange cylinder 22, the heat exchange medium is sent to the power generation component 3 through the circulation outlet. In the power generation component 3, the thermal energy of the heat exchange medium is converted into electrical energy, realizing energy conversion.

[0054] Therefore, the design of the circulation component ensures that the heat exchange medium can circulate efficiently within the system, thereby improving the efficiency of heat recovery. The coordinated operation of the circulation component and the heat exchange cylinder 22 guarantees the stability of the heat exchange process, making heat recovery more reliable. By adjusting the flow rate and temperature of the heat exchange medium, the system can adapt to different heat demands, improving the system's flexibility and adaptability. The efficient heat exchange process reduces energy waste, helps lower operating costs, and improves economic efficiency.

[0055] In some embodiments, the solid waste co-incineration and waste heat utilization system of the present invention further includes a filter assembly 5, which includes a filter element 51 and a filter screen 52. The filter element 51 has a filter cavity, and the filter screen 52 is disposed in the filter cavity and adapted to the inner wall of the filter cavity. The filter element 51 is connected between the conveying pipe 21 and the power generation assembly 3.

[0056] It is understandable that, such as Figures 1-4 As shown, the filter element 51 has a filter chamber. The filter chamber is designed to accommodate the filter screen 52 and ensure that the flue gas can come into contact with the filter screen 52 as it passes through the filter chamber. The filter screen 52 is installed inside the filter chamber and is fitted to the inner wall of the filter chamber. The filter screen 52 is typically made of high-temperature and corrosion-resistant materials, such as stainless steel wire mesh or ceramic fiber. The filter screen 52 is designed to effectively capture particulate matter and other pollutants in the flue gas.

[0057] In other words, the filter element 51 is connected between the delivery pipe 21 and the power generation unit 3. That is, the flue gas must be filtered through the filter element 51 before entering the power generation unit 3. In other words, the flue gas generated by the incinerator 1 will first pass through the filter element 51 before entering the power generation unit 3. Particulate matter and other pollutants in the flue gas will be captured by the filter screen 52, thereby reducing environmental pollution. The filter element 5 effectively protects the power generation unit 3 from damage by pollutants in the flue gas, extends the service life of the power generation unit 3, and ensures stable operation of the power generation unit 3.

[0058] Therefore, the design of filter assembly 5 effectively reduces pollutant emissions in flue gas, helping to meet increasingly stringent environmental standards. By filtering out particulate matter in the flue gas, contamination of the power generation assembly 3 can be reduced, thereby improving the operating efficiency of the power generation assembly 3. Filter assembly 5 protects the power generation assembly 3 from damage by pollutants, extends the service life of the equipment, and reduces maintenance costs.

[0059] Optionally, a fan 53 is also provided on the top of the filter element 51. The fan 53 is fixedly connected to the filter element 51, and the fan 53 can provide the power for rapid flow of flue gas in the filter element 51 to accelerate the flow rate of the filtered flue gas.

[0060] In some embodiments, the extension direction of the filter 52 is orthogonal to the extension direction of the delivery pipe 21.

[0061] It is understandable that, such as Figures 1-4 As shown, the extension direction of filter screen 52 is orthogonal to the extension direction of conveying pipe 21, which means that the flue gas needs to pass through filter screen 52 perpendicularly when passing through conveying pipe 21. This helps particulate matter and other pollutants in the flue gas to fully contact filter screen 52, thereby improving the filtration effect.

[0062] In other words, the orthogonal layout increases the contact area between the flue gas and the filter 52, allowing more particulate matter and other pollutants to be captured by the filter 52. Since the flue gas passes vertically through the filter 52, after prolonged use, impurities accumulated on the filter 52 can be dislodged by gravity, reducing clogging and improving flue gas purification efficiency, thereby reducing pollutant emissions. The filter 52 effectively protects the power generation unit 3 from damage by pollutants in the flue gas, extending its service life and ensuring stable operation.
