Abstract
Description
Technical Field
[0001] This application relates to the field of air pollution control technology, and in particular to an airflow optimization and regulation device for waste incinerators. Background Technology
[0002] Airflow optimization and regulation devices for waste incinerators are key components of urban solid waste treatment systems. They are primarily used to regulate the distribution, velocity, and turbulence intensity of airflow within the furnace to achieve goals such as complete waste combustion, dioxin suppression, and pollutant emission reduction. Currently, the industry commonly uses fixed baffles or pressure equalization holes for coarse airflow guidance, supplemented by rigid flange connections to secure external air supply / exhaust ducts. With increasingly stringent environmental standards and the growing demand for larger incinerators and higher heat load operations, the market is placing higher demands on the dynamic adaptability of airflow paths, the seismic and creep resistance of duct connections, and the long-term stable operation performance of the system. This is driving the iteration of airflow regulation technology towards refined guidance and adaptive locking integration.
[0003] Traditional waste incinerator airflow regulation devices have some technical limitations: First, the fixed flow guide structure cannot optimize the airflow direction in real time according to the fluctuation of the calorific value of the waste or the change of the temperature gradient in the combustion zone, resulting in local airflow collisions forming turbulent dissipation zones, reducing combustion efficiency and aggravating fly ash entrainment. At the same time, the imbalance of oxygen concentration in the high-temperature area can easily induce the escape of unburned CO gas. Second, the pipeline connection relies on the rigid locking of flange bolts, which can easily cause the sealing gaskets to loosen or the bolt stress to relax under the action of furnace thermal expansion, flue gas pulse or vibration load, leading to gas leakage or even pipeline misalignment and detachment, requiring frequent shutdowns for tightening and maintenance.

[0010] Optionally, a circular tube is provided on the outer side of the flow guiding structure, and a limiting ring is provided on the outer side of the circular tube.
[0011] With the above scheme, the first round tube is located outside the flow guiding structure, which can protect and support the flow guiding structure and ensure its stable operation; the second limiting ring is located outside the first round tube, which can limit the position of the first round tube and related components, prevent them from shifting, and ensure the overall structure is accurately positioned and reliably operated.

[0014] Optionally, the number of fixing rings is multiple, and they are evenly installed on the outside of the unblocking pipe.
[0015] With the above solution, multiple fixing rings are evenly installed on the outside of the unblocking pipe, which can not only reinforce the unblocking pipe at different locations, enhance its structural stability, and prevent deformation and loosening, but also ensure a stable and reliable connection between the unblocking pipe and adjacent components by evenly distributing the force.

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0028] This application discloses an airflow optimization and regulation device for waste incinerators.
[0029] Please see Figures 1 to 5 The waste incinerator airflow optimization and regulation device includes a flow guiding structure 3 for improving airflow efficiency, a fixing structure 2 for fixing external pipes, a fixing structure 2 fixedly connected to the outside of the flow guiding structure 3, and a dredging pipe 1 fixedly installed on one side of the fixing structure 2; the flow guiding structure 3 includes a circular pipe 31, a conveying pipe 32 fixedly connected to one side of the circular pipe 31, a sealing ring 34 fixedly installed on one side of the conveying pipe 32, a flow guiding groove 33 fixedly connected to the outside of the conveying pipe 32, and a filter cartridge 35 fixedly connected to the other side of the circular pipe 31.
[0030] It should be explained that the flow guiding structure 3 can improve airflow efficiency. One end of the circular tube 2 31 is connected to the conveying pipe 32. The conveying pipe 32 is not only responsible for conveying airflow, but also guides the airflow to spiral and accelerate its flow. At the same time, its end sealing ring 34 can tightly fit the external pipe to prevent air leakage. The filter cartridge 35 connected to the other end of the circular tube 2 31 can filter impurities in the airflow to avoid clogging the subsequent pipe. The fixing structure 2 can firmly fix the flow guiding structure 3 to the external pipe through components such as the circular tube 1 21. The unblocking pipe 1 connected to one side can restore the smooth flow of airflow by disassembling and cleaning or connecting backflushing equipment when the pipe is blocked, thereby ensuring stable and efficient airflow in the incinerator.
[0031] Please see Figures 1 to 5 The fixing structure 2 includes a circular tube 21. A washer 22 is fixedly connected to one side of the circular tube 21. A limiting ring 23 is fixedly connected to one side of the washer 22. A push rod 24 is fixedly connected to one side of the limiting ring 23. A fixing block 28 is fixedly provided on one side of the push rod 24. A slider 27 is provided on the other side of the fixing block 28. The slider 27 slides on the outside of the push rod 24. A limiting ring 25 is fixedly connected to one side of the limiting ring 23. A fixing block 26 and a fixing block 28 are fixedly connected to one side of the limiting ring 25.
[0032] It should be explained that in the fixed structure 2, one side of the round tube 21 is connected to the washer 22, which can buffer and enhance the sealing. The limiting ring 23 is fixed to one side of the washer 22, which can initially limit the relevant components. The push rod 24 is connected to one side of the limiting ring 23 and can be adjusted. The fixing block 28 on it is fixedly connected to the components. The slider 27 can slide outside the push rod 24 to achieve adjustment in conjunction with the push rod 24. The limiting ring 25 is also connected to one side of the limiting ring 23, further limiting the position of the components. At the same time, the fixing block 26 and fixing block 28 on its side can be firmly connected to other components. All components cooperate with each other to ensure that the fixed structure 2 can firmly connect the device to the external pipeline and achieve flexible adjustment.
[0033] Please see Figures 1 to 5 A fixing ring 4 is fixedly connected to the outside of the unblocking pipe 1, and a limit ring 25 is provided on one side of the fixing ring 4.
[0034] It should be explained that the fixing ring 4 fixedly connected to the outside of the unblocking pipe 1 can enhance the structural strength of the unblocking pipe 1 itself and prevent it from deforming or shaking during use. The limiting ring 25 set on one side of the fixing ring 4 can limit and constrain the fixing ring 4 and related components, restrict their range of movement, ensure that the relative position of the unblocking pipe 1 and other components is accurate and stable, and ensure the normal operation of the whole device.
[0035] Please see Figures 1 to 5 A circular tube 21 is provided on the outside of the flow guiding structure 3, and a limit ring 25 is provided on the outside of the circular tube 21.
[0036] It should be explained that the circular tube 21 set on the outside of the flow guide structure 3 can protect the flow guide structure 3 from damage by external collisions, and at the same time provide support for the flow guide structure 3 to ensure its stable operation. The limiting ring 25 on the outside of the circular tube 21 can limit the circular tube 21 and related components to prevent excessive displacement and ensure the accurate positional relationship between the flow guide structure 3 and the overall device.
[0037] Please see Figures 1 to 5 A circular tube 21 is provided on the outside of the guide channel 33, and the circular tube 21 is installed inside the unblocking pipe 1.
[0038] It should be explained that the circular tube 21 on the outside of the guide channel 33 not only wraps around the guide channel 33 for protection, but also guides the airflow to flow in a specific direction, making the airflow smoother. The circular tube 21 is installed inside the unblocking pipe 1 and can work closely with the unblocking pipe 1 to further stabilize the airflow direction and ensure that the airflow flows efficiently within the overall device.
[0039] Please see Figures 1 to 5 There are multiple fixing rings 4, which are evenly installed on the outside of the unblocking pipe 1.
[0040] It should be explained that multiple fixing rings 4 are evenly installed on the outside of the unblocking pipe 1. These fixing rings 4 can distribute the force and enhance the structural strength of the unblocking pipe 1 in all directions, preventing deformation and shaking during use, and making the connection between the unblocking pipe 1 and the surrounding components more stable.
[0041] Please see Figures 1 to 5 A limit ring 23 is provided on one side of the push rod 24, and a round tube 21 is provided on the outside of the limit ring 23.
[0042] It should be explained that the limiting ring 23 on one side of the push rod 24 can limit the push rod 24 to prevent it from moving excessively or deviating from its position, while the round tube 21 on the outside of the limiting ring 23 can provide support and protection, and at the same time assist the limiting ring 23 and other components to operate stably, ensuring the overall structure is stable and functions normally.
[0043] The implementation principle of the waste incinerator airflow optimization and regulation device in this application embodiment is as follows:
[0044] First, the circular tube 21 in the fixed structure 2 works with the gasket 22 to buffer and enhance the sealing performance. The limiting ring 23 and the limiting ring 25 limit the relevant components. The push rod 24 provides adjustment power. The slider 27 works with its sliding to achieve adjustment. The fixing block 26 and the fixing block 28 are firmly connected with other components, and the flow guiding structure 3 is firmly fixed on the external pipe, ensuring that the overall installation of the device is stable and can be flexibly adjusted.
[0045] Secondly, the circular tube 31 of the flow guiding structure 3 is the main frame, the conveying pipe 32 is responsible for conveying airflow, the outer flow guide groove 33 guides the airflow to spiral and accelerate the flow, and the end sealing ring 34 tightly fits the external pipe to prevent air leakage. The filter cartridge 35 connected to the other end of the circular tube 31 filters impurities in the airflow to avoid clogging the subsequent pipe. The circular tube 21 outside the flow guide groove 33 wraps around the flow guide groove 33 for protection and can also guide the airflow to flow in a specific direction. It works closely with the unblocking pipe 1 to stabilize the airflow direction and ensure efficient airflow.
[0046] Finally, during the blockage and maintenance phase, the unblocking pipe 1, fixed to one side of the fixed structure 2, can restore airflow when the pipe is blocked by disassembling and cleaning or connecting a backflushing device. At the same time, multiple fixing rings 4 evenly installed on the outside of the unblocking pipe 1 distribute the force, comprehensively enhancing the structural strength of the unblocking pipe 1, preventing it from deforming or shaking, making the connection between the unblocking pipe 1 and surrounding components more stable, and ensuring that the device can operate normally when dealing with abnormal situations such as blockage.
[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
