Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology for solid waste incineration, specifically to a waste gas treatment device for a solid waste incinerator. Background Technology

[0002] The existing solid waste incinerator exhaust gas treatment process has significant defects: 1. Quenching towers are susceptible to damage from solid particles. Exhaust gas is often directly introduced into the quenching tower without intercepting larger solid particles. These particles are carried by the high-speed airflow and collide with the spray nozzles, tower walls and guide plates of the quenching tower, which can easily cause nozzle blockage and component wear, resulting in reduced cooling efficiency, shortened lifespan of the quenching tower, frequent shutdowns for maintenance, increased costs and impact on continuous system operation. 2. The exhaust gas velocity is difficult to adapt, resulting in unstable treatment quality. Different solid waste incineration or fluctuations in operating conditions can lead to large differences in exhaust gas velocity. Existing quench towers lack the ability to adaptively adjust the different exhaust gas flow rates of different solid incineration: existing adjustments mostly rely on manual methods, which result in a delayed response and poor versatility of quench towers, making it difficult to meet diverse treatment needs. Summary of the Invention

[0003] The purpose of this invention is to provide a waste gas treatment device for a solid waste incinerator to solve the problems mentioned in the background art.

The L-shaped support rod is located at the center of the right end of the top surface near the bearing platform. The rotating column is located at the top of the L-shaped support rod through a second bearing. The gear is located at the top of the rotating column, and the gear meshes with the rack.

[0011] Preferably, the rotation of the rotating rod can drive the active circular plate to rotate, so that the outer wall of the active circular plate drives the driven central hole circular plate to rotate through friction with the outer wall of the driven central hole circular plate, and the rotation of the driven central hole circular plate drives the mutual movement of several cylindrical sliders and several rectangular sliders through several sliding grooves, thereby expanding or shrinking the center between several arrow plates.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the filtration platform in the filtration structure, can accurately intercept larger solid particles in the exhaust gas, preventing them from entering the subsequent quench tower with the exhaust gas. Compared with the traditional method of directly introducing exhaust gas into the quench tower, it can completely avoid the impact, wear, and blockage of larger solid particles on the spray nozzles, tower walls, and guide plates of the quench tower, reduce the damage to components and the decline in cooling quality caused by particle impact, and significantly extend the service life of the quench tower. 2. This invention establishes an adaptive mechanism for waste gas flow rate regulation, from mechanical transmission to flow adjustment, through the coordinated operation of the filtration structure and the regulating device. When the waste gas flow propels the filtration platform, the drive component converts the thrust into rotational force, which is transmitted to the active circular plate of the regulating device via the transmission component. The active circular plate drives the driven central hole circular plate to rotate through friction, thereby controlling the opening and closing degree of the arrow plate. The higher the waste gas flow rate, the smaller the arrow plate opening; the lower the flow rate, the larger the opening. This design can automatically adapt to the differentiated waste gas flow rates generated by different solid waste incineration processes, ensuring that the waste gas entering the quench tower always maintains a stable flow rate, improving the treatment quality of the waste gas, and is universal for waste gas that is not incinerated.

The number of cylindrical sliders 39 is the same as that of the arrow plates 38, and they are equidistantly arranged at the front end of several arrow plates 38. Several cylindrical sliders 39 are embedded in one end of several grooves 33. Several cylindrical sliders 39 can move along the inner wall of the grooves 33. Several cylindrical sliders 39 and several rectangular sliders 37 respectively limit the movement of several cylindrical sliders 39, and provide a limiting driving relationship for scaling or enlarging between several cylindrical sliders 39.The rotation of the rotating rod 293 drives the active circular plate 31 to rotate, causing the outer wall of the active circular plate 31 to rub against the outer wall of the driven central hole circular plate 32, thus driving the driven central hole circular plate 32 to rotate. The rotation of the driven central hole circular plate 32, through several sliding grooves 33, drives several cylindrical sliders 39 and several rectangular sliders 37 to move in coordination, causing the center between several arrow plates 38 to expand or shrink. This regulating device 3 can adjust the final flow rate of different gas flows generated by different solid combustion processes entering the quench tower; it is an adaptive regulation and has a certain degree of versatility.

[0023] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, and the specific work is as follows: Traditional solid waste incineration waste gas enters the quench tower directly from the incinerator. Larger solid particles in the waste gas, if present for extended periods, can damage the equipment structure within the quench tower. Furthermore, different solid particles produce waste gas flows at varying velocities after combustion, and the lack of velocity regulation leads to insufficient cooling of the waste gas. This invention addresses these problems by connecting the front end of the waste gas pipe 13 to the waste gas outlet of the incinerator, and connecting and fixing the output port 1610 within the second circular plate 168 to the input port of the quench tower, thus forming a closed treatment device. The waste gas flow velocity from the incinerator drives the filter platform 25, causing the gear 285 to convert the thrust of the airflow into rotational force. This rotation, through the transmission assembly, drives the rotating rod 293 to operate. The circular plate 31 rotates, and through the friction between the active circular plate 31 and the outer wall of the driven central hole circular plate 32, the driven central hole circular plate 32 is driven to rotate. The rotation of the driven central hole circular plate 32 drives the center between several arrow plates 38 to shrink. Different solid wastes will produce different airflow velocities. When the exhaust gas velocity of solid waste incineration is greater and there is more exhaust gas, the filter platform 25 is pushed to move backward more, making the opening between several arrow plates 38 smaller. Similarly, the lower the exhaust gas velocity of the airflow waste, the less the filter platform 25 is pushed to move backward, making the opening between several arrow plates 38 larger. The present invention can adaptively adjust the different exhaust gas flow rates generated after the incineration of different solid wastes to ensure a stable exhaust gas input into the quench tower.

[0024] The filter platform 25 filters larger solid particles in the initial exhaust gas, protecting the quench tower from these particles as it enters. Traditional filter platforms 25 are either rigidly connected or nonexistent, making them susceptible to damage or loosening from prolonged exposure to high-velocity exhaust gas flow. In this invention, the filter platform 25, through the interaction of the transmission rod 24, the circular block 23, and the high-temperature spring 22, can move within the exhaust gas duct 13 with limited movement. The high-temperature spring 22 plays a crucial role. When the filter platform 25 is subjected to the thrust of the exhaust gas flow, it provides buffering protection, extending its service life. Simultaneously, the filter platform 25 drives several operating arrow plates 38 to reset. The high-temperature spring 22 is in a deformed state and stores its own rebound force. Similarly, when the exhaust gas stops flowing, the high-temperature spring 22 rebounds, driving the filter platform 25 to reset. Thus, the high-temperature spring 22 uses its stored rebound force to drive all components connected to and operating the filter platform 25 to reset.
