Description

Technical Field

[0001] The present invention relates to the technical field of waste incineration power generation, and particularly to a special power generation thermal equipment for waste incineration. Background Art

[0002] The special power generation thermal equipment for waste incineration is specifically a waste heat boiler device. The waste heat boiler is a key equipment in the process of waste incineration power generation. It uses the waste heat generated during waste incineration to generate electricity. This equipment consists of multiple parts, including a steam drum, heating surfaces, a flue duct at the furnace inlet section, etc., and can efficiently recover and utilize the heat energy generated by waste incineration and convert it into electrical energy.

[0003] Compared with the prior art, since the flow trend of high-temperature flue gas in the waste heat boiler is from the inlet to the outlet, the side of the heating surface facing the air inlet will absorb more heat, while the side facing away from the air inlet will absorb less heat. This uneven heat distribution phenomenon will lead to a reduction in the thermal efficiency of the heating surface. Specifically: the side facing the air inlet will have local overheating due to absorbing too much heat, which will not only reduce the service life of the heating surface but also pose a safety hazard. The side facing away from the air inlet wastes the heat energy because it absorbs less heat and cannot be effectively converted into energy forms such as steam or hot water, resulting in a reduction in the thermal efficiency of the entire waste heat boiler. Due to the uneven heat distribution on the heating surface, problems such as deformation and cracks will also occur on the heating surface, increasing the equipment maintenance cost and downtime.

[0004] Moreover, when there are temperature differences in different parts of the heating surface, it will lead to different expansion amounts in each part. However, the rigid support structure in the prior art cannot adapt to this uneven expansion, thus generating additional stresses inside the heating surface. For example, the part on the side facing the air inlet mentioned above has a high temperature and a large expansion amount, while the part on the side facing away from the air inlet has a relatively low temperature and a small expansion amount. The rigid support structure cannot adjust according to this difference, further exacerbating the uneven distribution of thermal stress and increasing the risk of deformation and damage of the heating surface.

[0005] In addition, the high-temperature flue gas generated by the waste incinerator enters the waste heat boiler only after preliminary treatment and filtration, which leads to impurities adhering to the outer wall of the heating surface. The adhesion of impurities to the outer wall of the heating surface is equivalent to forming an additional thermal resistance layer 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 heating surface metal material, resulting in a significant decrease in the heat transfer efficiency.

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

[0007] To solve the above technical problems, the present invention provides a special power generation and heating equipment for waste incineration to solve the technical problems raised in the above background art.

[0008] To achieve the above object, the technical solution adopted by the present invention is: a special power generation and heating equipment for waste incineration, including a heating surface, and a dynamic heating mechanism is arranged outside the heating surface, and the dynamic heating mechanism is used to adjust the heated part to improve the heat absorption efficiency.

[0009] Further, the dynamic heating mechanism includes a heating cylinder installed inside the heating surface, fins are installed on the outside of the heating cylinder, buffer bins are installed at both the upper and lower ends of the fins, and torsion springs are installed inside the buffer bins.

[0010] Further, a boiler furnace is installed outside the heating surface, a boiler drum is installed above the boiler furnace, the heating surface is integrally composed of a plurality of O-shaped pipes, and the plurality of O-shaped pipes are arranged in an internal and external staggered manner, and the bent part above the heating surface is located inside the boiler drum, and the rest are located inside the boiler furnace.

[0011] By adopting the above technical solution, the plurality of pipes are arranged in a staggered manner, making the flow path of the flue gas between the tube bundles more complex and enhancing the turbulent flow effect.

[0012] Further, the heating cylinder is an overall straight tube, 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, a through shaft is fixedly connected to the thin side of the heating cylinder, and both the fins and the through shaft are made of boron nitride material.

[0013] By adopting the above technical solution, the good thermal stability and chemical stability of boron nitride also ensure the long-term stable operation of the fins in a harsh high-temperature flue gas environment.

[0014] Further, a connecting plate is installed on the outer wall of the heating surface, the buffer bin above the heating surface is rotatably connected to the connecting plate, the fins are in the shape of rectangular sheets, and are arranged at a certain inclination angle with the flue gas inlet in the initial state.

[0015] By adopting the above technical solution, a adjustable method is designed to make the back of the heating cylinder also receive heat, increasing the heat absorbed per unit time.

[0016] Further, both ends of the torsion spring are fixedly connected to the connecting plate and the buffer bin respectively.

[0017] Further, an elastic member is installed between every two adjacent buffer bins, the elastic member is composed of a central ball and a corrugated elastic cord, and the corrugated elastic cords are fixedly connected to the buffer bins.

[0018] By adopting the above technical solution, the combined action of the elastic member and the coil spring provides a basic resistance force for the fins, so that the fins will not rotate randomly under the action of a slight wind force.

[0019] Further, an impurity treatment mechanism is provided outside the boiler chamber. The impurity treatment mechanism is used for hierarchically treating the flue gas impurities entering the inside of the boiler chamber. The impurity treatment mechanism includes a flue gas pipe communicated with the inside of the boiler chamber. An upper baffle and a lower baffle are installed inside the flue gas pipe, and an adapter frame is installed below the flue gas pipe.

[0020] Further, the upper baffle is uniformly fixedly connected to the upper half wall of the flue gas pipe, and the lower baffle is uniformly rotatably connected to the lower half wall of the flue gas pipe through a rotating shaft. Both the upper baffle and the lower baffle are designed in an inclined manner, and the two are distributed in a staggered parallel manner.

[0021] By adopting the above technical solution, some impurity particles will be blocked by the lower baffle from continuing to flow due to excessive direction change and the action of gravity.

[0022] Further, support members are fixedly connected to the rear side walls of the lower baffle. One ends of the support members far away from the rotating shaft are fixedly connected to the inner wall of the flue gas pipe. An index plate is fixedly connected to the end position of the rotating shaft. In the initial state, the index plate is parallel to the lower baffle.

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

[0024] Further, through grooves are uniformly formed below the flue gas pipe at positions close to the lower baffle, and the flue gas pipe and the adapter frame are movably connected through the through grooves.

[0025] By adopting the above technical solution, the adapter frame can be directly taken out for cleaning, avoiding the cumbersome process of disassembling multiple components in the traditional cleaning method.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) By introducing the heating cylinder and cooperating it with the flue gas, the heating surface is made adjustable. When the flue gas discharge is large and the flow rate is fast, the flue gas drives the heating cylinder to rotate through the fins, so that the back surface of the heating cylinder is also heated, increasing the heat absorbed per unit time, strengthening the heat exchange process, thereby 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, and increasing the energy output.

[0027] Among them, the fins are made of a heat-conducting material such as boron nitride. Although the fins will drive the heating surface to rotate under the conditions of a large flue gas discharge volume and high flow rate, since the fins continuously absorb heat while always being in contact with the high-temperature flue gas, they can ensure that the heat is quickly transferred to the heating cylinder. The good thermal stability and chemical stability of boron nitride also ensure that the fins can work stably for a long time in the harsh high-temperature flue gas environment.

[0028] Secondly, when the flue gas discharge volume is small and the flow rate is slow, the blocking and diversion effect of the fins on the flue gas makes the flow field of the flue gas in the waste heat boiler more uniform, avoiding the situation of too fast or too slow local flow rate, reducing the flow resistance, ensuring the rapid flow of the flue gas, further improving the overall heat exchange efficiency. At the same time, as the fins rotate to expand the flow area between different pipes, it also helps to optimize the flue gas flow field.

[0029] Compared with the prior art, the device effectively avoids the local overheating phenomenon on the side facing the air inlet, reduces problems such as deformation and cracks of the heating surface caused by uneven heat distribution, reduces the maintenance frequency and difficulty of the equipment, shortens the downtime, reduces the economic losses caused by maintenance and downtime, and improves the utilization rate and production efficiency of the equipment.

[0030] Among them, the overall heating surface is arranged in a staggered manner by a plurality of pipes, making the flow path of the flue gas between the tube bundles more complex, enhancing the turbulent flow effect. Turbulent flow 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] Among them, the combined action of the elastic member and the coil spring provides a basic resistance for the fins, so that the fins will not rotate randomly under the action of a slight wind force. This helps to 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 heating surface and the flue gas.

[0032] Secondly, due to the action of the elastic member 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 heating surface, and thus can keep the heating surface clean and improve the heat exchange efficiency.

[0033] Among them, the through shaft supports the heating surface from top to bottom, and can provide a stable supporting force when the heating surface expands and contracts thermally, preventing the heating surface from being deformed and affecting its working state. By maintaining the stability of the heating surface, the mechanical stress caused by thermal expansion and contraction is reduced, thereby prolonging the service life of the heating surface and reducing the downtime and maintenance cost caused by replacing the heating surface.

[0034] (2) In terms of manufacturing, whether it is the heating cylinder or the fins, their shapes are regular and the structures are relatively unified. The heating cylinder is in a straight cylinder shape, which is convenient for mold making and mass forming. This consistency enables each component to adopt the same manufacturing process and procedure during production, without the need for complex customized production, and it is easy to achieve assembly line production, reflecting high practicality in the manufacturing process.

[0035] From the installation perspective, since the structures of each pipeline are the same, during the assembly process of the waste heat boiler, installers can operate according to unified standards and procedures, reducing the installation difficulty and time cost. In the subsequent maintenance stage, if a component is damaged and needs to be replaced, pipes and fins of the same specifications are easy to obtain and replace, without the need for special adaptation and debugging for different structures, greatly reducing the maintenance cost and equipment downtime, ensuring the continuous and stable operation of the waste heat boiler, and demonstrating remarkable practicality in practical applications.

[0036] (3) This device effectively controls the flow path of high-temperature flue gas by introducing upper baffles and lower baffles and arranging them in a staggered manner. When high-temperature flue gas enters the interior of the flue gas pipeline, 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 downward. Subsequently, when the flue gas passes through the lower baffle, its flow direction will change again. Due to excessive change in direction and the action of gravity, some impurity particles will be blocked by the lower baffle and unable to continue flowing. Since multiple groups of upper baffles and lower baffles are provided, through the combined action of the upper baffle and the lower baffle, it is possible to effectively prevent some impurity particles from flowing into the interior of the waste heat boiler, thereby improving the purification efficiency of the flue gas, which helps to reduce the ash accumulation phenomenon inside the waste heat boiler and extend the service life of the equipment.

[0037] Among them, when the 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 board rotates and tends to be vertical following the lower baffle, they can intuitively judge that the impurity particles inside the flue gas pipeline have accumulated to a certain extent and need to be cleared immediately. Through the rotation of the indicator board, the accumulation situation of impurity particles inside the flue gas pipeline can be monitored in real time, without the need to stop the machine for inspection, improving the real-time and accuracy of monitoring.

[0038] Among them, when the staff discovers through the indicator board that the impurity particles inside the flue gas pipeline have accumulated to a certain extent, they can directly draw out the adapter frame for cleaning, avoiding the cumbersome process of disassembling multiple components in the traditional cleaning method, thereby greatly improving the cleaning efficiency. This cleaning process is not only simple and fast, but also can effectively expose the area where impurities accumulate, making the cleaning work more direct and efficient.

Detailed implementation manners

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0052] It should be noted that the structures and working principles of devices such as the above-mentioned boiler furnace 1, boiler drum 11, heating surface 12, etc. belong to the prior art and will not be elaborated here.

[0053] Embodiment 1: Please refer to Figures 1 to 3 As shown, a special power generation and heating equipment for garbage incineration includes a heating surface 12, and a dynamic heating mechanism 2 is arranged outside the heating surface 12. The dynamic heating mechanism 2 is used to adjust the heated 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 bins 25 are installed at both the upper and lower ends of the fins 23, and torsion springs 26 are installed inside the buffer bins 25.

[0055] It should be noted that a boiler furnace 1 is installed outside the heating surface 12, a boiler drum 11 is installed above the boiler furnace 1. The heating surface 12 is integrally composed of a plurality of O-shaped pipes, and the plurality of O-shaped pipes are arranged in an internal and external staggered manner. The bent part above the heating surface 12 is located inside the boiler drum 11, and the rest of the parts are located inside the boiler furnace 1. The heating cylinder 22 is an overall straight pipe. The heating cylinder 22 is divided into a thick side and a thin side. The fins 23 are fixedly connected to the thick side part of the heating cylinder 22. A through shaft 24 is fixedly connected to the thin side part of the heating cylinder 22. Both the fins 23 and the through shaft 24 are made of boron nitride material. A connecting plate 21 is installed on the outer wall of the heating surface 12. The buffer bin 25 above the heating surface 12 is rotatably connected to the connecting plate 21. The fins 23 are in the shape of rectangular sheets and are arranged at a certain inclination angle with the flue gas inlet in the initial state. Both ends of the torsion spring 26 are fixedly connected to the connecting plate 21 and the buffer bin 25 respectively. An elastic member 27 is installed between every two adjacent buffer bins 25. The elastic member 27 is composed of a central ball and a corrugated elastic cord, and the corrugated elastic cords are fixedly connected to the buffer bins 25.

[0056] Specifically, in the initial state, the position of the fins 23 is as Figure 4 shown, and after rotation, the position of the fins 23 is as Figure 5 shown. When the high-temperature flue gas discharge volume is large and the flow rate is fast, a large amount of high-temperature flue gas quickly rushes into the boiler furnace 1 from the flue gas pipeline 31. The high-speed flowing flue gas impacts on the inclined fins 23. Due to the contact area and angle factors between the fins 23 and the flue gas, a force that pushes the fins 23 to rotate will be generated. The fins 23 are fixed to the thick side part of the heating cylinder 22, so the heating cylinder 22 is driven to rotate. After rotation, it is as Figure 5 shown. Since the fins 23 are made of boron nitride material, after the position of the thick side part rotates, the fins 23 continuously absorb heat because they are always in contact with the high-temperature flue gas, and quickly transfer the heat to the heating cylinder 22 by virtue of good thermal conductivity.

[0057] With the rotation of the heated cylinder 22, the original uneven heating situation is improved. The back of the heated cylinder 22 can also fully contact the high-temperature flue gas, increasing the heat absorbed per unit time. At the same time, due to the rotation of the heated 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 enhancing 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] Since the combined action of the elastic member 27 and the coil spring 26 provides a basic resistance force for the fins 23, when the flow rate of the high-temperature flue gas entering the boiler chamber 1 is slow and the discharge is small, it is not sufficient to provide enough power to drive the fins 23 to drive the heated cylinder 22 to rotate. At this time, the position of the fins 23 is basically not affected, as specifically shown in Figure 4 However, the fins 23 still play an important role, blocking and diverting the slowly flowing flue gas, making the flow field of the flue gas in the boiler chamber 1 more uniform, avoiding the situation of too slow local flow rate, 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] Embodiment 2: On the basis of Embodiment 1, please refer to Figures 7 to 11 As shown, an impurity treatment mechanism 3 is provided outside the boiler chamber 1. The impurity treatment mechanism 3 is used to hierarchically treat the flue gas impurities entering the inside of the boiler chamber 1. The impurity treatment mechanism 3 includes a flue gas pipe 31 communicating with the inside of the boiler chamber 1. An upper baffle 32 and a lower baffle 33 are installed inside the flue gas pipe 31, and an adapter frame 36 is installed below the flue gas pipe 31.

[0060] It should be noted that the upper baffle 32 is uniformly fixedly connected to the upper half wall of the flue gas pipe 31, and the lower baffle 33 is uniformly rotatably connected to the lower half wall of the flue gas pipe 31 through a rotating shaft 34. Both the upper baffle 32 and the lower baffle 33 are designed in an inclined manner, and the two are arranged in a staggered parallel distribution. A support member 35 is fixedly connected to the rear side wall of each lower baffle 33. One end of the support member 35 away from the rotating shaft 34 is fixedly connected to the inner wall of the flue gas pipe 31. An index plate is fixedly connected to the end position of the rotating shaft 34. In the initial state, the index plate is parallel to the lower baffle 33. Through grooves are uniformly opened below the flue gas pipe 31, and the through grooves are located at positions close to the lower baffle 33. The flue gas pipe 31 and the adapter frame 36 are movably connected through the through grooves.

[0061] Specifically, as shown in Figure 8 is the initial position of the lower baffle 33, as shown in Figure 10The figure shows the situation where the position of the lower baffle 33 changes to the maximum. 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 evenly rotated and connected to the lower half wall of the flue gas duct 31 through the rotating shaft 34, and is in the initial set position. The indicator plate thereon remains parallel to the lower baffle 33.

[0062] Since the upper baffle 32 is evenly fixed on the upper half wall of the flue gas duct 31 and is designed to be inclined, when the high-temperature flue gas enters the flue gas duct 31, it will first be blocked by the upper baffle 32, and part of the flue gas changes its flow direction and flows downward. In this process, the impurity particles in the flue gas are driven by the airflow and the action of gravity and also move downward. When the flue gas and impurities continue to flow downward, they encounter the lower baffle 33 which is also inclined and staggered. The staggered layout of the lower baffle 33 and the upper baffle 32 changes the flow path of the flue gas again. Due to multiple changes in direction and their own gravity, some impurity particles are difficult to continue to flow with the flue gas and are intercepted by the lower baffle 33 and accumulated at the angle between the lower baffle 33 and the flue gas duct 31. Since there are multiple groups of upper baffles 32 and lower baffles 33, after multiple rounds of blocking, a large number of impurity particles are effectively intercepted in the flue gas duct 31, which greatly reduces the impurities flowing to the boiler chamber 1 and improves the flue gas purification efficiency, thereby helping to reduce the dust 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 through the rotating shaft 34, and the limiting support 35 limits its rotation to ensure that the lower baffle 33 can only rotate to a maximum extent to remain vertical with the flue gas duct 31. When the 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 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 cleared immediately.

[0064] When it is determined that the impurities need to be cleaned, since through grooves are evenly opened at the bottom of the flue gas duct 31 and are movably connected to the adapter frame 36 through the through grooves, the staff can directly pull out the adapter frame 36. During the impurity accumulation process, the adapter frame 36 takes over part of the impurities 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, avoiding the cumbersome process of disassembling multiple components in the traditional cleaning method, thereby greatly improving the cleaning efficiency.

[0065] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
