Description

Technical Field

[0001] This invention relates to the field of waste incineration power generation technology, specifically to a dedicated thermal power generation device for waste incineration. Background Technology

[0002] The waste incineration-specific power generation equipment is specifically a waste heat boiler device. The waste heat boiler is a key piece of equipment in the waste incineration power generation process. It uses the waste heat generated during waste incineration to generate electricity. This equipment consists of multiple parts, including the boiler drum, heating surface, and flue gas duct at the furnace opening. It can efficiently recover and utilize the heat energy generated by waste incineration and convert it into electrical energy.

[0003] Compared to existing technologies, in waste heat boilers, the flow trend of high-temperature flue gas is from inlet to outlet. The side of the heating surface facing the air inlet absorbs more heat, while the side away from the air inlet absorbs less heat. This uneven heat distribution leads to a decrease in the thermal efficiency of the heating surface. Specifically, the side facing the air inlet absorbs too much heat, resulting in localized overheating. This not only reduces the service life of the heating surface but also poses safety hazards. On the other hand, the side away from the air inlet absorbs less heat, and its heat energy is wasted, failing to be effectively converted into energy forms such as steam or hot water. This results in a decrease in the overall thermal efficiency of the waste heat boiler. Furthermore, the uneven heat distribution on the heating surface can lead to problems such as deformation and cracks, increasing equipment maintenance costs and downtime.

[0004] Furthermore, when there are temperature differences in different parts of the heated surface, the expansion amount of each part will be different. The rigid support structure in the existing technology cannot adapt to this uneven expansion, which will generate additional stress inside the heated surface. For example, as mentioned above, the part facing the air inlet has a higher temperature and a larger expansion amount, while the part facing away from the air inlet has a relatively lower temperature and a smaller expansion amount. The rigid support structure cannot adjust according to this difference, which further aggravates the uneven distribution of thermal stress and increases the risk of deformation and damage to the heated surface.

[0005] In addition, the high-temperature flue gas generated by the waste incinerator enters the waste heat boiler after only preliminary treatment and filtration, which causes impurities to adhere to the outer wall of the heating surface. The impurities adhering to the outer wall of the heating surface are equivalent to forming an additional thermal resistance between the heating surface and the high-temperature flue gas. Heat transfer needs to pass through this impurity layer, and the thermal conductivity of impurities is usually much lower than that of the metal material of the heating surface, which greatly reduces the heat transfer efficiency.

[0006] Therefore, in view of this, the present invention proposes a special power generation and thermal equipment for waste incineration to make up for and improve the shortcomings of the prior art. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a dedicated thermal power generation device for waste incineration, thereby resolving the technical issues raised in the background section.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a special power generation and thermal equipment for waste incineration, including a heating surface, wherein a dynamic heating mechanism is provided on the outside of the heating surface, and the dynamic heating mechanism is used to adjust the heating part to improve the heat absorption efficiency.

[0009] Furthermore, the dynamic heating mechanism includes a heating cylinder installed inside the heating surface. Fins are installed on the outside of the heating cylinder, and buffer chambers are installed at the upper and lower ends of the fins. Coil springs are installed inside the buffer chambers.

[0010] Furthermore, a boiler chamber is installed on the outside of the heating surface, and a boiler drum is installed above the boiler chamber. The heating surface is composed of multiple O-shaped pipes, which are arranged in an alternating pattern. The curved part above the heating surface is located inside the boiler drum, while the rest is located inside the boiler chamber.

[0011] By adopting the above technical solution, multiple pipes are arranged in an interlaced manner, which makes the flow path of flue gas between the pipe bundles more complex and enhances the turbulence effect.

[0012] Furthermore, the heating cylinder is a straight cylindrical pipe, and the heating cylinder is divided into a thick side and a thin side. The fins are fixedly connected to the thick side of the heating cylinder, and a through shaft is fixedly connected to the thin side of the heating cylinder. Both the fins and the through shaft are made of boron nitride.

[0013] By adopting the above technical solution, the excellent thermal and chemical stability of boron nitride also ensures that the fins can work stably for a long time in harsh high-temperature flue gas environments.

[0014] Furthermore, a connecting plate is installed on the outer wall of the heating surface, and the buffer chamber above the heating surface is rotatably connected to the connecting plate. The fins are rectangular and are initially set at a certain angle to the flue gas inlet.

[0015] By adopting the above technical solution and designing an adjustable method, the back of the heating cylinder is also heated, increasing the amount of heat absorbed per unit time.

[0016] Furthermore, the two ends of the coil spring are fixedly connected to the connecting plate and the buffer chamber, respectively.

[0017] Furthermore, an elastic element is installed between every two adjacent buffer chambers. The elastic element is composed of a central sphere and a corrugated elastic cable, and the corrugated elastic cable is fixedly connected to the buffer chamber.

[0018] By adopting the above technical solution, the combined action of the elastic component and the coil spring provides a basic resistance for the fins, preventing them from rotating arbitrarily under slight wind force.

[0019] Furthermore, an impurity treatment mechanism is provided outside the boiler chamber. The impurity treatment mechanism is used to treat the flue gas impurities entering the boiler chamber in stages. The impurity treatment mechanism includes a flue gas duct that communicates with the inside of the boiler chamber. An upper baffle and a lower baffle are installed inside the flue gas duct. An adapter frame is installed below the flue gas duct.

[0020] Furthermore, the upper baffle is uniformly and fixedly connected to the upper half of the flue gas duct, and the lower baffle is uniformly and rotatably connected to the lower half of the flue gas duct via a rotating shaft. Both the upper and lower baffles are designed with an inclination and are distributed in a staggered parallel manner.

[0021] By adopting the above technical solution, some impurity particles will be prevented from continuing to flow due to excessive changes in direction and the effect of gravity.

[0022] Furthermore, the rear sidewall of the lower baffle is fixedly connected to a support member, and the end of the support member away from the rotating shaft is fixedly connected to the inner wall of the flue gas duct. An index plate is fixedly connected to the end of the rotating shaft, and the index plate is parallel to the lower baffle in the initial state.

[0023] By adopting the above technical solution, when the indicator plate rotates with the lower baffle and tends to be vertical, it can be intuitively judged that the impurity particles inside the flue gas duct have accumulated to a certain extent.

[0024] Furthermore, a through groove is evenly provided below the flue gas duct, the through groove is located near the lower baffle, and the flue gas duct and the adapter frame are movably connected through the through groove.

[0025] By adopting the above technical solution, the adapter frame can be directly extracted for cleaning, avoiding the cumbersome process of disassembling multiple parts required in traditional cleaning methods.

[0026] Compared with the prior art, the beneficial effects of the present invention are: (1) By introducing a heating cylinder to cooperate with the flue gas, the heating surface is adjustable. When the flue gas discharge volume is large and the flow rate is fast, the flue gas drives the heating cylinder to rotate through the fins, so that the back of the heating cylinder is also heated, increasing the heat absorbed per unit time and strengthening the heat exchange process. This improves the efficiency of the waste heat boiler in converting high-temperature flue gas heat energy into energy forms such as steam or hot water, and increases energy output.

[0027] The fins are made of boron nitride, a thermally conductive material. Although the fins will drive the heated surface to rotate under conditions of high flue gas volume and high flow rate, the fins will continuously absorb heat while in constant contact with the high-temperature flue gas. This ensures that the heat is quickly transferred to the heated cylinder. The good thermal and chemical stability of boron nitride also ensures that the fins can work stably for a long time in harsh high-temperature flue gas environments.

[0028] Secondly, when the flue gas discharge is small and the flow rate is slow, the fins block and divert the flue gas, making the flow field of the flue gas in the waste heat boiler more uniform. This avoids situations where the flow rate is too fast or too slow in some areas, reduces flow resistance, ensures the rapid flow of flue gas, and further improves the overall heat exchange efficiency. At the same time, as the fins rotate, they expand the flow area between different pipes, which also helps to optimize the flue gas flow field.

[0029] Compared with existing technologies, this device effectively avoids localized overheating on the side facing the air inlet, reduces problems such as deformation and cracks caused by uneven heat distribution on the heated surface, lowers the frequency and difficulty of equipment maintenance, shortens downtime, reduces economic losses caused by maintenance and downtime, and improves equipment utilization and production efficiency.

[0030] The heating surface is composed of multiple pipes arranged in an interlaced pattern, which makes the flow path of flue gas between the tube bundles more complex and enhances the turbulence effect. Turbulence can more effectively break the flue gas boundary layer, increase the heat exchange area and heat transfer coefficient between the flue gas and the heating surface, thereby improving the heat transfer efficiency.

[0031] The combined action of the elastic element and the coil spring provides a basic resistance to the fins, preventing them from rotating arbitrarily under slight wind. This helps maintain the stability and reliability of the fins, ensuring that they can rotate flexibly when needed to adjust the contact angle and relative position between the heated surface and the flue gas.

[0032] Secondly, due to the action of the elastic element and the coil spring, the fins will be affected by the reverse elastic force after the reset rotation. This reverse elastic force helps to shake off the dust particles attached to the heated surface, thereby keeping the heated surface clean and improving the heat exchange efficiency.

[0033] The through shaft supports the heated surface from top to bottom, providing stable support when the heated surface expands and contracts due to heat. This prevents the heated surface from deforming and affecting its working condition. By maintaining the stability of the heated surface, the mechanical stress caused by thermal expansion and contraction is reduced, thereby extending the service life of the heated surface and reducing downtime and maintenance costs caused by replacing the heated surface.

[0034] (2) In terms of manufacturing, both the heating cylinder and the fins are regular in shape and relatively uniform in structure. The heating cylinder is straight, which is convenient for mold making and mass production. This consistency allows each part to adopt the same manufacturing process and flow during production, without the need for complex customized production, making it easy to achieve assembly line production. This reflects high practicality from the manufacturing process.

[0035] From an installation perspective, because all the pipe structures are identical, installers can operate according to unified standards and procedures during the assembly of the waste heat boiler, reducing installation difficulty and time costs. In the subsequent maintenance phase, if a component is damaged and needs to be replaced, pipes and fins of the same specifications are easy to obtain and replace, eliminating the need for special adaptation and debugging for different structures. This significantly reduces maintenance costs and equipment downtime, ensuring that the waste heat boiler can operate continuously and stably, demonstrating significant practicality in real-world applications.

[0036] (3) This device effectively controls the flow path of high-temperature flue gas by introducing upper and lower baffles and making them staggered. When high-temperature flue gas enters the flue gas duct, the upper baffle can block part of the flue gas and make it flow downward. During this process, the impurity particles in the flue gas will also sink. Subsequently, when the flue gas passes through the lower baffle, its flow direction will change again. Some impurity particles will be blocked by the lower baffle due to excessive change in direction and gravity. Since there are multiple sets of upper and lower baffles, the cooperation between the upper and lower baffles can effectively prevent some impurity particles from flowing into the waste heat boiler, thereby improving the flue gas purification efficiency. This helps to reduce the ash accumulation inside the waste heat boiler and extend the service life of the equipment.

[0037] When impurity particles in the flue gas accumulate to a certain extent on the lower baffle, the lower baffle will rotate due to the blowing action of the flue gas. When the staff finds that the indicator plate tends to be vertical as it rotates with the lower baffle, they can intuitively judge that the impurity particles inside the flue gas duct have accumulated to a certain extent and need to be removed immediately. By rotating the indicator plate, the accumulation of impurity particles inside the flue gas duct can be monitored in real time without stopping the machine for inspection, thus improving the real-time performance and accuracy of the monitoring.

[0038] In this system, when staff detect a certain level of impurities accumulated inside the flue gas duct using the indicator panel, they can directly remove the adapter frame for cleaning. This avoids the cumbersome process of disassembling multiple components required in traditional cleaning methods, significantly improving cleaning efficiency. This cleaning process is not only simple and quick but also effectively exposes areas where impurities have accumulated, making the cleaning work more direct and efficient.

[0051] 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.

[0052] It should be noted that the structure and working principle of the above-mentioned components such as boiler chamber 1, boiler drum 11, and heating surface 12 are existing technologies and will not be described in detail here.

[0053] Example 1: Please refer to Figures 1 to 3 As shown, a waste incineration-specific power generation thermal equipment includes a heating surface 12, and a dynamic heating mechanism 2 is provided on the outside of the heating surface 12. The dynamic heating mechanism 2 is used to adjust the heating part to improve the heat absorption efficiency.

[0054] Please refer to Figures 2 to 7 As shown, the dynamic heating mechanism 2 includes a heating cylinder 22 installed inside the heating surface 12. Fins 23 are installed on the outside of the heating cylinder 22. Buffer chambers 25 are installed at both the upper and lower ends of the fins 23. Coil springs 26 are installed inside the buffer chambers 25.

[0055] It should be noted that the boiler chamber 1 is installed on the outside of the heating surface 12, and the boiler drum 11 is installed above the boiler chamber 1. The heating surface 12 is composed of multiple O-shaped pipes arranged in an alternating pattern. The curved part above the heating surface 12 is located inside the boiler drum 11, while the rest is located inside the boiler chamber 1. The heating drum 22 is a straight cylindrical pipe, divided into a thick side and a thin side. Fins 23 are fixedly connected to the thick side of the heating drum 22, and a through shaft 24 is fixedly connected to the thin side of the heating drum 22. Both 23 and the through shaft 24 are made of boron nitride. A connecting plate 21 is installed on the outer wall of the heating surface 12. The buffer chamber 25 above the heating surface 12 is rotatably connected to the connecting plate 21. The fin 23 is rectangular and initially set at a certain angle to the flue gas inlet. The two ends of the coil spring 26 are fixedly connected to the connecting plate 21 and the buffer chamber 25 respectively. An elastic element 27 is installed between every two adjacent buffer chambers 25. The elastic element 27 is composed of a central ball and a corrugated elastic cable, and the corrugated elastic cable is fixedly connected to the buffer chamber 25.

[0056] Specifically, the initial position of fin 23 is as follows: Figure 4 As shown, the position of fin 23 after rotation is as follows: Figure 5 As shown, when the high-temperature flue gas discharge volume is large and the flow rate is high, a large amount of high-temperature flue gas rapidly flows from the flue gas pipe 31 into the boiler chamber 1. The high-speed flowing flue gas impacts the fins 23, which are set at an inclined angle. Due to the contact area and angle between the fins 23 and the flue gas, a force is generated that pushes the fins 23 to rotate. The fins 23 are fixed to the thick side of the heating cylinder 22, thus driving the heating cylinder 22 to rotate. After rotation, it is as follows: Figure 5 As shown, since the fin 23 is made of boron nitride, after the thick side rotates to a new position, the fin 23 continues to absorb heat because it is always in contact with the high-temperature flue gas, and quickly transfers the heat to the heated cylinder 22 due to its good thermal conductivity.

[0057] As the heating cylinder 22 rotates, the uneven heating is improved, and the back of the heating cylinder 22 can fully contact the high-temperature flue gas, increasing the heat absorbed per unit time. At the same time, due to the rotation of the heating cylinder 22, the space between the fins 23 changes, expanding the flow area between different pipes, optimizing the flue gas flow field, further strengthening the heat exchange process, and improving the efficiency of the waste heat boiler in converting the heat energy of high-temperature flue gas into energy forms such as steam or hot water.

[0058] Because the combined action of the elastic element 27 and the coil spring 26 provides a basic resistance for the fins 23, when the high-temperature flue gas velocity and discharge volume entering the boiler chamber 1 are slow, it is insufficient to provide enough power to make the fins 23 drive the heating cylinder 22 to rotate. At this time, the position of the fins 23 is basically unaffected, specifically as follows: Figure 4 As shown, however, the fins 23 still play an important role in blocking and diverting the slow-flowing flue gas, making the flow field of the flue gas in the boiler chamber 1 more uniform, avoiding the situation of excessively slow local flow velocity, ensuring that the flue gas can flow effectively inside, fully contact the heating surface 12, realize heat exchange, and improve the overall heat exchange efficiency.

[0059] Example 2: Based on Example 1, please refer to... Figures 7 to 11 As shown, an impurity treatment mechanism 3 is provided on the outside of the boiler chamber 1. The impurity treatment mechanism 3 is used to process the flue gas impurities entering the boiler chamber 1 in layers. The impurity treatment mechanism 3 includes a flue gas pipe 31 that is connected to the inside of the boiler chamber 1. An upper baffle 32 and a lower baffle 33 are installed inside the flue gas pipe 31. An adapter frame 36 is installed below the flue gas pipe 31.

[0060] It should be noted that the upper baffle 32 is uniformly and fixedly connected to the upper half of the flue gas duct 31, and the lower baffle 33 is uniformly and rotatably connected to the lower half of the flue gas duct 31 through the rotating shaft 34. Both the upper baffle 32 and the lower baffle 33 are inclined and are distributed in a staggered parallel manner. The rear side wall of the lower baffle 33 is fixedly connected to the support member 35. The end of the support member 35 away from the rotating shaft 34 is fixedly connected to the inner wall of the flue gas duct 31. An index plate is fixedly connected at the end of the rotating shaft 34. In the initial state, the index plate is parallel to the lower baffle 33. A through groove is uniformly opened at the bottom of the flue gas duct 31. The through groove is located near the lower baffle 33, and the flue gas duct 31 and the adapter frame 36 are movably connected through the through groove.

[0061] Specifically, such as Figure 8 The image shows the initial position of the lower baffle 33, as follows: Figure 10The diagram shows the situation where the position of the lower baffle 33 is changed to the maximum extent. When the high-temperature flue gas carrying impurities is discharged from the waste incinerator and enters the flue gas duct 31 connected to the boiler chamber 1, the lower baffle 33 is connected to the lower half of the flue gas duct 31 by rotating evenly through the rotating shaft 34 and is in the initial set position. The indicator plate on it is parallel to the lower baffle 33.

[0062] Since the upper baffle 32 is evenly fixed to the upper half of the flue gas duct 31 and has an inclined design, when high-temperature flue gas enters the flue gas duct 31, it will first be blocked by the upper baffle 32. Some of the flue gas will change its flow direction and flow downward. During this process, the impurity particles in the flue gas will also move downward due to the airflow and gravity. When the flue gas and impurities continue to flow downward, they will encounter the lower baffle 33, which is also inclined and staggered. The staggered layout of the lower baffle 33 and the upper baffle 32 will change the flow path of the flue gas again. Some impurity particles will have difficulty following the flue gas due to multiple changes in direction and their own gravity. They will be intercepted by the lower baffle 33 and accumulate at the angle between the lower baffle 33 and the flue gas duct 31. Since there are multiple sets of upper baffle 32 and lower baffle 33, after multiple rounds of blocking, a large number of impurity particles will be effectively intercepted in the flue gas duct 31, which will greatly reduce the impurities flowing into the boiler chamber 1, improve the flue gas purification efficiency, and thus help reduce the ash accumulation inside the boiler chamber 1 and extend the service life of the equipment.

[0063] The lower baffle 33 is rotatably connected to the lower part of the flue gas duct 31 via a rotating shaft 34, and its rotation is restricted by a limit support 35, ensuring that the lower baffle 33 can only rotate to a position perpendicular to the flue gas duct 31. When impurity particles in the flue gas accumulate to a certain extent on the lower baffle 33, the lower baffle 33 will rotate due to the blowing action of the flue gas, and at the same time drive the indicator plate at the end of the rotating shaft 34 to rotate together. When the staff finds that the indicator plate is vertical, they can intuitively judge that the impurity particles inside the flue gas duct 31 have accumulated to a certain extent and need to be cleaned immediately.

[0064] When it is determined that impurities need to be cleaned, since the flue gas duct 31 is evenly provided with through slots and is movably connected to the adapter frame 36 through the through slots, the staff can directly pull out the adapter frame 36. During the impurity accumulation process, the adapter frame 36 receives some of the impurities that are blocked by the lower baffle 33. Therefore, after the adapter frame 36 is pulled out, the impurity accumulation area is fully exposed, and the staff can clean the impurities efficiently and conveniently. This avoids the cumbersome process of disassembling multiple parts in the traditional cleaning method and greatly improves the cleaning efficiency.

[0065] 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.
