Description

Technical Field

[0001] This invention relates to the field of waste incineration technology, specifically a waste incineration system utilizing a dry distillation gas furnace. Background Technology

[0002] The gas heat carrier pyrolysis technology mainly uses a pyrolysis furnace for three stages of processing, including a drying section, a pyrolysis section, and a cooling section. The heat carrier for drying and pyrolysis mainly comes from the hot flue gas after the combustion of self-produced coal gas and the gas after temperature adjustment mixed with waste flue gas or coal gas. The cooling of the product generally adopts a combination of direct cooling with oxygen-free gas and indirect cooling with a water jacket.

[0003] Waste incineration refers to the thermal oxidation treatment of combustible organic waste at high temperatures. Under complete combustion conditions, the removal rate of organic matter can reach 99%. Because it is a relatively complete and thorough method of waste decomposition and destruction, it is widely used for the treatment of hazardous waste. Furthermore, incineration can significantly reduce the volume of waste, and the small amount of ash produced can be sent to landfills, greatly reducing the amount of waste requiring landfill disposal. There are many types of incinerators for waste incineration, mainly including grate incinerators, liquid jet incinerators, multi-stage incinerators, fluidized bed incinerators, and slag incinerators.

[0004] Existing gas pyrolysis furnaces mainly use hot flue gas and waste gas generated after coal gas combustion to dry and pyrolyze products, which requires a lot of energy. In order to reduce energy consumption, waste can be directly burned to replace coal gas in generating heat. However, because waste is prone to ash accumulation, the combustion of waste is slow and incomplete, and the heat generated is insufficient for pyrolysis and drying, which can easily affect the quality of products produced by the gas pyrolysis furnace. Summary of the Invention

[0005] To overcome the shortcomings of existing dry distillation gas furnaces that use waste combustion instead of coal gas for heating, which are prone to ash accumulation and slow, incomplete combustion, resulting in insufficient heat for dry distillation and drying and affecting product quality, this application provides a waste incineration system using a dry distillation gas furnace. The system uses a motor to control the rotation of an eccentric wheel. A gear on the outside of the eccentric wheel meshes with a gear ring, controlling the rotation of a material tray at one end of the loading platform. Simultaneously, the eccentric wheel drives a control shaft to rotate within the receiving cavity inside the material tray. This allows the control shaft to shake the waste at the top of the tray, rotating the tray and causing relative movement between the waste and the tray. The waste then pushes the ash from multiple ash outlets to the bottom, ensuring efficient combustion and maximizing heat generation.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A waste incineration system utilizing a pyrolysis gas furnace includes a pyrolysis gas furnace, a feeding structure, and a collection structure. The bottom inner side of the pyrolysis gas furnace provides space for waste gas combustion.

[0008] The feeding structure is located on one side of the dry distillation gas furnace;

[0009] The collection structure is located inside the dry distillation gas furnace;

[0010] The feeding structure has one end located outside the dry distillation gas furnace and the other end located inside the dry distillation gas furnace. The feeding structure and the receiving structure move synchronously.

[0011] In one possible implementation, the feeding structure includes a moving part and a rotating part, the moving part providing support for the rotating part to move within the dry distillation gas furnace.

[0012] In one possible implementation, the movable part includes a loading platform, with multiple support legs machined on both sides of the bottom of one end of the loading platform. The bottom ends of the support legs are fitted with rollers. The rotating part includes a loading tray. The top and bottom of the other end of the loading platform are interconnected, and the loading tray is rotatably connected to the interior of the other end of the loading platform.

[0013] In one possible implementation, two guide rails are provided on one side of the bottom of the dry distillation gas furnace. The top of each guide rail is machined with a positioning groove. One end of each guide rail is inserted into the bottom of the dry distillation gas furnace and is assembled and fixed to it by bolts. The roller is rolled and connected inside the positioning groove.

[0014] In one possible implementation, the outer wall of the bottom wall of the dry distillation gas furnace is integrally formed with a combustion feed port, and a cover plate is machined in the middle of the loading platform, with one side of the cover plate fitting against the surface of the combustion feed port.

[0015] In one possible implementation, a gear ring is machined on the outer side of the bottom of the loading tray, and a gear is meshed with the bottom of the gear ring. An eccentric wheel is pin-connected to the inside of the gear. One end of the eccentric wheel is connected to a motor via a drive belt and two drive wheels. The motor is mounted on the top of one end of the loading platform.

[0016] In one possible implementation, the outer side of the material tray is machined with multiple ash-draining holes, the center of the material tray is machined with a receiving cavity, the outer side of the eccentric wheel is pin-connected to a control shaft, the control shaft protrudes from the top of the material tray from the inside of the receiving cavity, and the control shaft is rotatably connected to the inside of the receiving cavity.

[0017] In one possible implementation, the receiving structure includes a fixed portion and a movable portion, the fixed portion providing guidance for the ash falling into the movable portion.

[0018] In one possible implementation, the fixed part includes two wing plates, the movable part includes an ash collection tray, the wing plates are symmetrically distributed on the top of both sides of the ash collection tray, the wing plates are inclined and one side is in contact with the inner wall of the incineration feed port.

[0019] In one possible implementation, one end of the ash collection tray is assembled with a connecting frame, which is located outside the dry distillation gas furnace, and one end of the connecting frame is assembled with the bottom of one end of the material carrying platform, while the other end of the ash collection tray is attached to the inner wall of the dry distillation gas furnace.

[0020] The beneficial effects of this application are as follows:

[0021] Firstly, in this solution, the eccentric wheel is rotated by a motor. The gear on the outside of the eccentric wheel meshes with the gear ring, controlling the rotation of the material tray inside one end of the material platform. At the same time, the eccentric wheel drives the control shaft to rotate inside the receiving cavity on the inner side of the material tray. This allows the material tray to be rotated when the waste at the top of the material tray is shaken by the control shaft, so that the waste and the material tray move relative to each other. The waste pushes the ash from multiple ash holes to the bottom, which helps to ensure the combustion effect of the waste and maximize the heat generation.

[0022] Secondly, in this solution, by setting an ash collection tray directly below the loading tray, two wing plates can be used to guide the collection of carbon ash generated by the combustion of waste at the top of the loading tray. This facilitates the removal of carbon ash from the inside of the ash collection tray when the loading platform moves the loading tray from inside the dry distillation gas furnace to the outside, allowing the carbon ash to fall to the bottom between the two guide rails.

[0031] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0032] Example 1:

[0033] This embodiment describes the specific structure of a waste incineration system utilizing a dry distillation gas furnace. See details below. Figures 1-7 As shown, the device includes a dry distillation gas furnace 1 with an inner bottom for providing space for waste gas combustion, a feeding structure 3 located on one side of the dry distillation gas furnace 1, and a receiving structure 5 located inside the dry distillation gas furnace 1. One end of the feeding structure 3 is located outside the dry distillation gas furnace 1, while the other end is located inside the dry distillation gas furnace 1. The feeding structure 3 and the receiving structure 5 move synchronously. The feeding structure 3 includes a moving part and a rotating part. The moving part includes a loading platform 305. Multiple support legs 301 are machined on both sides of the bottom of one end of the loading platform 305. Rollers 302 are assembled and connected to the bottom of the support legs 301. The rotating part includes a loading tray 308. Multiple ash holes 309 are machined on the outer side of the loading tray 308.

[0034] Among them, such as Figure 3 As shown, by setting the material tray 308 inside one end of the material platform 305, when the material platform 305 moves by the rollers 302 at the bottom of the support leg 301, the moving part can provide support for the rotating part to move inside the dry distillation gas furnace 1, thereby facilitating the laying of strip-shaped waste on the top of the material tray 308.

[0035] Secondly, such as Figure 3 and Figure 4As shown, by connecting the top and bottom of the other end of the loading platform 305 to each other, and rotating the loading tray 308 inside the other end of the loading platform 305, the ash produced by the waste burning at the top of the loading tray 308 can fall to the bottom through multiple ash holes 309.

[0036] Furthermore, in order to control the trajectory of the loading platform 305 within the carbonization gas furnace 1, such as... Figure 1 and Figure 2 As shown, two guide rails 4 are provided on one side of the bottom of the dry distillation gas furnace 1. The top of each guide rail 4 is machined with a positioning groove 6. After one end of each guide rail 4 is inserted into the bottom of the dry distillation gas furnace 1 and fixed to it with bolts, the two guide rails 4 are kept parallel.

[0037] Meanwhile, by making the roller 302 roll-connected inside the positioning groove 6, the roller 302 can be positioned, and the roller 302 is restricted from disengaging from the guide rail 4 when it moves at the top of the guide rail 4.

[0038] Furthermore, such as Figure 1 As shown, the outer wall of the bottom wall of the dry distillation gas furnace 1 is integrally formed with a combustion feed port 2, and a cover plate 307 is machined in the middle of the loading platform 305. By moving the loading platform 305 inside the dry distillation gas furnace 1, the surface of one side of the cover plate 307 is brought into contact with the surface of the combustion feed port 2, which can block the channel connecting the inside of the dry distillation gas furnace 1 with the outside, and prevent the exhaust gas generated during the combustion process from being discharged to the outside.

[0039] like Figure 4 As shown, a gear ring 304 is machined on the outer side of the bottom of the material tray 308. A gear 303 is meshed with the bottom of the gear ring 304. An eccentric wheel 311 is pin-connected inside the gear 303. One end of the eccentric wheel 311 is connected to a motor 306 through a transmission belt and two transmission wheels. A receiving cavity is machined in the center of the material tray 308. A control shaft 310 is pin-connected to the outside of the eccentric wheel 311.

[0040] In this way, by assembling the motor 306 to the top of one end of the loading platform 305, the eccentric wheel 311 can drive the gear 303 to rotate, so that the gear 303 can drive the loading plate 308 to rotate inside the loading platform 305 by using the gear ring 304.

[0041] At the same time, when the eccentric wheel 311 drives the gear 303 to rotate, it can also drive the control shaft 310 to rotate, so that the control shaft 310, which is eccentrically connected to the eccentric wheel 311, rotates inside the receiving cavity. Since the control shaft 310 protrudes from the top of the material tray 308 from the inside of the receiving cavity, it can intermittently shake the waste spread on the top of the material tray 308.

[0042] By adopting the above technical solution:

[0043] The above design features a feeding structure 3 with one end inside and the other outside of the dry distillation gas furnace 1. When the motor 306 controls the eccentric wheel 311 to rotate via the transmission belt and pulley, the gear 303 outside the eccentric wheel 311 meshes with the gear ring 304, controlling the rotation of the loading plate 308 inside one end of the loading platform 305. Simultaneously, the eccentric wheel 311 drives the control shaft 310 to rotate inside the receiving cavity inside the loading plate 308. This allows the control shaft 310 to shake the waste at the top of the loading plate 308, and the rotation of the loading plate 308 allows the waste to move relative to the loading plate 308. The waste then pushes the ash from the multiple ash holes 309 to the bottom, preventing a large accumulation of ash from affecting the combustion of the waste. This helps ensure the combustion effect of the waste and maximizes the heat generation.

[0044] Example 2:

[0045] Based on Example 1, this example describes the specific structure of the receiving structure 5, such as... Figure 2 and Figure 3 As shown, the collecting structure 5 includes a fixed part and a movable part. The fixed part includes two wing plates 502, and the movable part includes a collecting pan 501.

[0046] By symmetrically distributing the wing plates 502 on the top of both sides of the ash collection pan 501 and setting the wing plates 502 in an inclined form, since one side of the wing plate 502 is in contact with the inner wall of the incineration feed port 2 and the other end of the ash collection pan 501 is in contact with the inner wall of the dry distillation gas furnace 1, the ash can slide along the top surface of the wing plate 502 to the bottom, thereby achieving the effect of using the fixed part to guide the ash falling into the moving part.

[0047] Secondly, to facilitate the removal of carbon ash from the interior of the dry distillation gas furnace 1 by the ash collection tray 501, such as... Figure 2 and Figure 4 As shown, a connecting frame 503 is assembled and connected to one end of the ash collection tray 501, so that the connecting frame 503 is located outside the dry distillation gas furnace 1, and one end of it is assembled and connected to the bottom of one end of the material loading platform 305. When the material loading platform 305 moves outward inside the dry distillation gas furnace 1, it can drive the ash collection tray 501 to drag the carbon ash collected inside it into the space between the two guide rails 4 for cleaning.

[0048] The specific operating steps are as follows:

[0049] S1. By means of multiple support legs 301 and multiple rollers 302 machined at the bottom of one end of the loading platform 305, the rollers 302 roll in the positioning grooves 6 on the guide rail 4, and one end of the loading platform 305 is pulled out from the inside of the dry distillation gas furnace 1, and waste is laid in the loading tray 308 inside one end of the loading platform 305.

[0050] S2. Control one end of the loading platform 305 to be reset inside the dry distillation gas furnace 1. During the combustion process at the top of the loading plate 308, the motor 306 controls the eccentric wheel 311 to rotate through the transmission belt and pulley. This causes the gear 303, which meshes with the gear ring 304 on the outside of the eccentric wheel 311, to control the loading plate 308 to rotate inside one end of the loading platform 305. At the same time, the eccentric wheel 311 drives the control shaft 310 to rotate inside the receiving cavity on the inside of the loading plate 308 to shake the waste and use the waste to move the carbon ash on the top of the loading plate 308.

[0051] S3. The dislodged ash falls to the bottom from multiple ash holes 309. Some of the ash falls directly to the inside of the ash collection tray 501, while the other part is guided by the two wing plates 502 and gathers inside the ash collection tray 501.

[0052] S4. When replenishing waste to the top of the loading tray 308, the loading platform 305 drives the ash collection tray 501 from the inside to the outside of the dry distillation gas furnace 1 through the connecting frame 503, thereby using the ash collection tray 501 to drag the carbon ash on its inner side to be discharged between the two guide rails 4.

[0053] By adopting the above technical solution:

[0054] The above design involves setting an ash collection tray 501 directly below the loading tray 308 and connecting the ash collection tray 501 to the loading platform 305 via a connecting frame 503. When the ash produced by the combustion of waste at the top of the loading tray 308 falls to the bottom from multiple ash holes 309, it can be guided by two wing plates 502 and collected by the ash collection tray 501. When the loading platform 305 moves the loading tray 308 from the inside to the outside of the dry distillation gas furnace 1, the connecting frame 503 can be used to drive the ash collection tray 501 to pull out the ash inside, so that the ash falls to the bottom between the two guide rails 4 for centralized processing.

[0055] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
