Description

Technical Field

[0001] This utility model relates to the field of two-combustion chambers, and in particular to a structural device for an energy-saving and heat-storing two-combustion chamber for solid waste incineration. Background Technology

[0002] With increasingly stringent environmental protection requirements, solid waste incineration, as a highly efficient waste disposal method, is widely used in industrial and municipal waste treatment. Among these systems, the energy-saving regenerative secondary combustion chamber is a core component, and its structural design directly impacts combustion efficiency, pollutant emissions, and energy recovery rates. Optimizing the secondary combustion chamber structure to achieve complete combustion of combustible gases and efficient heat recovery is of great significance for promoting the green and sustainable development of the solid waste incineration industry.

[0003] Currently, most common solid waste incineration secondary combustion chambers adopt a simple cylindrical structure, with combustible gases being directly introduced into the secondary combustion chamber through pipes. These devices mainly rely on the diffusion and mixing characteristics of the gases themselves to facilitate the mixing of different combustible gases during combustion.

[0004] However, existing solid waste incineration secondary combustion chamber devices generally suffer from insufficient gas mixing. Since different combustible gases are usually directly delivered to the secondary combustion chamber without an effective mixing guidance structure, the gas is difficult to distribute evenly in a short time. This uneven mixing state causes local temperatures inside the secondary combustion chamber to be too high or too low, which not only reduces combustion efficiency but also causes incomplete combustion, producing a large amount of harmful pollutants. At the same time, it affects the stable operation and service life of the equipment. Therefore, an energy-saving and regenerative secondary combustion chamber structure device for solid waste incineration is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides an energy-saving and heat-storing secondary combustion chamber structure device for solid waste incineration. It aims to improve the problem that in the use of traditional equipment, different combustible gases are usually directly transported into the interior of the secondary combustion chamber, which easily leads to insufficient mixing between different gases and causes the local temperature inside the secondary combustion chamber to be too high or too low.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A solid waste incineration energy-saving and heat-storing secondary combustion chamber structure device includes a secondary combustion chamber, a material valve is provided at the bottom of the secondary combustion chamber, a pressure relief valve is fixedly connected to the top of the secondary combustion chamber, a mixing component is provided inside the secondary combustion chamber, and multiple connecting pipes are fixedly connected to the outer wall of the secondary combustion chamber, with heat insulation components provided inside the multiple connecting pipes.

[0008] The mixing component includes a flow guide plate, the outer wall of which is fixedly connected to the inner wall of the secondary combustion chamber. A venturi tube is fixedly connected to the top of the flow guide plate. Multiple flow dividers in a ring array are fixedly connected to the inner wall of the flow guide plate. A connecting plate is fixedly connected to the top of the inner wall of the flow guide plate. Multiple flow guide holes are opened inside the connecting plate. A discharge plate is fixedly connected to the top of the connecting plate.

[0010] The inner walls of the guide plate and the discharge plate are bowl-shaped and symmetrically distributed between them.

[0011] As a further description of the above technical solution:

[0012] The inner wall of the Venturi tube has an arc-shaped structure, and the diameters at both ends are larger than the diameter in the middle.

[0013] As a further description of the above technical solution:

[0014] The outer wall of each of the diverter plates has a triangular structure, and the inner wall of each of the guide holes has a circular structure.

[0015] As a further description of the above technical solution:

[0016] The insulation component includes multiple ceramic fiber boards, and the outer wall of each ceramic fiber board is fixedly connected to the inner wall of the connecting pipe.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the arc-shaped structure of the inner wall of the guide plate provides an obstacle to the upward flow of gas, and the flow divider separates the gas. At the same time, the venturi tube is used to mix multiple gases, achieving a good mixing effect between different combustible gases. This solves the problem that in traditional equipment, different combustible gases are usually directly delivered to the interior of the secondary combustion chamber, which easily leads to insufficient mixing between different gases and causes local temperatures in the secondary combustion chamber to be too high or too low. This enhances the uniformity of gas and the stability of combustion.

[0025] 2. In this utility model, the rotation of the sealing ball prevents heat from escaping from the interior of the secondary combustion chamber, and the ceramic fiber board is used to block and insulate the heat on the inner wall, preventing further outward dissipation. This achieves the effect of preventing the high temperature of the inner wall of the secondary combustion chamber from escaping through the connecting pipe, solving the problem that in traditional equipment, heat is easily dissipated through the pipes connected to the secondary combustion chamber, thus reducing the temperature inside the secondary combustion chamber, and enhancing the heat preservation effect inside the secondary combustion chamber.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides one embodiment: a solid waste incineration energy-saving regenerative secondary combustion chamber structure device, including a secondary combustion chamber 1. When in use, high-temperature flue gas and unburned materials from the incinerator enter the secondary combustion chamber 1. Fuel and air are supplemented by a rationally arranged burner, forming a strong turbulent mixing environment, ensuring sufficient contact between the flue gas and oxygen; simultaneously, the high temperature is maintained to ensure complete combustion of unburned materials within a sufficient residence time, decomposing harmful components. Finally, the treated flue gas, meeting standards, is discharged into subsequent purification components. This is prior art and will not be described in detail here. A material valve is installed at the bottom of the secondary combustion chamber 1 to control the combustion chamber 1. The internal material is discharged to prevent unburned material from remaining inside the secondary combustion chamber 1. A pressure relief valve 2 is fixedly connected to the top of the secondary combustion chamber 1. The pressure relief valve 2 is used to regulate the gas pressure inside the secondary combustion chamber 1 to prevent excessive pressure inside the secondary combustion chamber 1 from causing equipment damage. A mixing component is installed inside the secondary combustion chamber 1 to promote the full mixing of different combustible gases and improve combustion efficiency and stability. Multiple connecting pipes 3 are fixedly connected to the outer wall of the secondary combustion chamber 1. The connecting pipes 3 are used to transport different combustible gases into the secondary combustion chamber 1. Heat insulation components are installed inside the multiple connecting pipes 3 to reduce heat loss inside the secondary combustion chamber 1 and maintain a stable temperature inside the secondary combustion chamber 1.

[0035] The mixing assembly includes a guide plate 4, whose outer wall is fixedly connected to the inner wall of the secondary combustion chamber 1. The guide plate 4 guides the flow direction of the combustible gas, forming turbulence to promote gas mixing. A Venturi tube 5 is fixedly connected to the top of the guide plate 4, which accelerates the gas flow rate and generates turbulence to enhance the collision and mixing of gas molecules. Multiple flow dividers 7 in a ring array are fixedly connected to the inner wall of the guide plate 4, which divide the gas into multiple small gas streams to increase the contact area between the gases. A connecting plate 8 is fixedly connected to the top of the inner wall of the guide plate 4, which prevents the gas from rising rapidly and prolongs the residence time of the gas at the bottom of the secondary combustion chamber 1. Multiple guide holes 9 are opened inside the connecting plate 8, which are used to guide the divided gas... The gas is introduced into the Venturi tube 5. The top of the connecting plate 8 is fixedly connected to the discharge plate 6. The discharge plate 6 is used to evenly distribute the mixed gas on the top of the inner wall of the secondary combustion chamber 1. The inner walls of the guide plate 4 and the discharge plate 6 are bowl-shaped and symmetrically distributed. The bowl-shaped structure is used to guide the gas flow direction and form a circulating flow to enhance the mixing effect. The inner wall of the Venturi tube 5 is arc-shaped with a larger diameter at both ends than in the middle. The arc-shaped structure is used to generate the Venturi effect, accelerate the gas flow rate and form turbulence. The outer wall of each diverter plate 7 is triangular. The triangular structure is used to divide the gas flow and form multiple small airflows to enhance the mixing effect. The inner wall of each guide hole 9 is circular. The circular structure is used to reduce gas flow resistance and ensure smooth gas passage.

[0036] Reference Figure 1 , Figure 4 and Figure 5The insulation component includes multiple ceramic fiber boards 10. The ceramic fiber boards 10 are used to insulate heat and prevent the high temperature inside the secondary combustion chamber 1 from dissipating outwards through the connecting pipe 3. The outer wall of each ceramic fiber board 10 is fixedly connected to the inner wall of the connecting pipe 3. The ceramic fiber board 10 and the inner wall of the connecting pipe 3 are tightly fitted to ensure the heat insulation effect. A sealing ball 11 is rotatably connected to the inner wall of each ceramic fiber board 10. The sealing ball 11 is used to control the opening and closing of the connecting pipe 3 and adjust the gas flow path. Each sealing ball 11 is fully fitted to the inner wall of the ceramic fiber board 10 to ensure a tight seal and prevent heat leakage. Each sealing ball 11 has a connecting hole 15 inside. The connecting hole 15 is used for... After the sealing ball 11 rotates, a gas channel is formed, allowing gas to pass through. Each connecting pipe 3 is fixedly connected to a bracket 14 at its top. The bracket 14 is used to support the motor 13 and ensure the stable operation of the motor 13. Each bracket 14 is fixedly connected to a motor 13 at its top. The motor 13 is used to drive the sealing ball 11 to rotate and control the opening and closing of the connecting hole 15. Each motor 13 output end is fixedly connected to a transmission column 12. The transmission column 12 is used to transmit the power of the motor 13 to the sealing ball 11 to realize the rotation of the sealing ball 11. The bottom of each transmission column 12 is fixedly connected to the top of the sealing ball 11. The transmission column 12 and the sealing ball 11 are fixedly connected to ensure the accuracy of power transmission.

[0037] Working Principle: During the mixing of different combustible gases, different combustible gases enter the secondary combustion chamber 1 through the connecting pipe 3 at the bottom of the secondary combustion chamber 1. Due to their lower density, the gases naturally rise. The arc-shaped structure at the top of the inner wall of the guide plate 4 guides the airflow direction. The connecting plate 8 provides some obstruction to the channel between the guide plate 4 and the venturi tube 5, preventing the gas from moving upwards too quickly. This prolongs the time the different combustible gases spend at the bottom of the secondary combustion chamber 1, causing them to collide with the bottom of the inner wall, thus creating strong turbulence. Subsequently, as the combustible gases pass over the surface of the splitter plate 7, the triangular structure on the outer wall of the splitter plate 7 divides the gas into multiple smaller airflows, allowing for better mixing. The mixed gas then enters the inner wall of the venturi tube 5 through the guide hole 9. Due to the venturi tube... 5. The cross-sectional area of ​​the middle region of the inner wall is relatively small. At this time, the gas flow rate reaches its maximum value and the gas flow state is extremely unstable, which easily forms turbulence. Turbulence makes the movement of gas molecules disordered and irregular. Under the action of turbulence, the molecules of different gases interpenetrate and collide with each other, which greatly increases the contact area and mixing opportunities between them, and promotes the full mixing of gases. These mixed gases will be evenly distributed on the top of the inner wall of the secondary combustion chamber 1 through the arc structure of the inner wall of the discharge plate 6, which facilitates subsequent combustion. In the end, a good mixing effect of different combustible gases is achieved. This solves the problem that in the traditional equipment, different combustible gases are usually directly delivered to the interior of the secondary combustion chamber 1, which easily leads to insufficient mixing between different gases and causes the local temperature inside the secondary combustion chamber 1 to be too high or too low. This enhances the uniformity of gas and the stability of combustion.

[0038] During the heat preservation process inside the secondary combustion chamber 1, the motor 13 is started, and the output end of the motor 13 drives the sealing ball 11 at the bottom of the transmission column 12 to rotate 90 degrees, so that the connecting hole 15 inside the sealing ball 11 fits against the inner wall of the ceramic fiber board 10. This prevents the heat inside the secondary combustion chamber 1 from dissipating through the connecting pipe 3, which does not need to be connected to the outside. At the same time, the heat insulation and high temperature resistance properties of the ceramic fiber board 10 prevent the high temperature of the inner wall of the secondary combustion chamber 1 from dissipating outward through the connecting pipe 3. This solves the problem that in traditional equipment, heat is easily dissipated outward through the pipes connected to the secondary combustion chamber 1, thereby reducing the internal temperature of the secondary combustion chamber 1 and enhancing the heat preservation effect inside the secondary combustion chamber 1.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
