Description

Technical Field

[0001] This utility model relates to the technical field of waste gas purification equipment, and in particular to a waste gas purification equipment for waste incineration power generation. Background Technology

[0002] In the waste-to-energy industry, the incineration process generates waste gas containing large amounts of particulate matter, harmful gases, and sparks. Direct emission of this waste gas not only causes air pollution, harming the ecological environment and human health, but the particulate matter can also clog subsequent treatment equipment, and the sparks pose a significant safety hazard. Waste-to-energy waste gas purification equipment, as a core environmental and safety guarantee device, plays a crucial role in pre-treating waste gas: on the one hand, it reduces the pressure on subsequent purification by separating particulate matter, ensuring that the final emission of waste gas meets environmental standards.

[0003] However, traditional exhaust gas purification equipment focuses on particulate matter separation (such as simple cyclone separators and bag filters), lacking a dedicated spark-proof structure. If exhaust gas containing sparks is allowed to enter the conveyor fan or cyclone separator, the high-speed sparks can easily ignite the lubricating oil inside the fan, or come into contact with flammable particles deposited in the cyclone separator (such as carbon particles produced by burning plastics), causing combustion. This will not only damage the equipment but also cause the production line to shut down.

[0004] For example, Chinese Patent No. CN 211886027 U discloses a waste gas purification device for waste incineration, including a support base, a bag filter box, a middle fixed vertical plate, an embedded control box, and a water bath adsorption box. The device body is supported and installed on the base. The middle fixed vertical plate is installed inside the device body, and the middle fixed vertical plate divides the device body into the bag filter box on the left and the water bath adsorption box on the right. An air pump is supported and fixed on the top of the device body. An exhaust valve is installed on the top of the bag filter box. The exhaust valve is connected to the inlet of the air pump through a connecting air pipe. A diversion outlet pipe is supported and placed at the bottom of the water bath adsorption box.

[0005] The patent suffers from the aforementioned technical problems. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0019] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0020] To address the problems existing in the background technology, this application proposes the following technical solution: a waste gas purification device for waste incineration power generation, characterized in that it includes a conveying pipe 1, a conveying fan 4, and a cyclone separator 6. The output end of the conveying pipe 1 is fixedly connected to a first pipe 3. The input end of the conveying fan 4 is fixedly connected to the first pipe 3. The output end of the conveying fan 4 is fixedly connected to a second pipe 5, which is fixedly connected to the input end of the cyclone separator 6. The conveying pipe 1 is equipped with a spark-proof component and a cleaning component. A tapered pipe 2 is fixedly connected to the input end of the conveying pipe 1, and an air inlet pipe is fixedly connected to one end of the tapered pipe 2. A collection hopper 7 is detachably connected to the bottom of the cyclone separator 6, and an output pipe is fixedly connected to the top of the cyclone separator 6.

[0021] The core process link for waste gas purification consists of the conveying pipe 1, the conveying fan 4, and the cyclone separator 6. The conveying pipe 1 guides the flow of waste gas. The conveying fan 4 draws waste gas from the conveying pipe 1 through the first pipe 3 and then sends it to the cyclone separator 6 through the second pipe 5, providing stable power for waste gas delivery and ensuring that the waste gas can continuously and efficiently enter the purification stage, avoiding waste gas stagnation or incomplete purification due to insufficient airflow. The tapered pipe 2 at the input end of the conveying pipe 1 cooperates with the air inlet pipe. The tapered pipe 2 can enlarge the waste gas inlet diameter, reduce the resistance when the waste gas enters, and guide the waste gas to enter the conveying pipe 1 evenly, avoiding local airflow turbulence that may affect the subsequent spark prevention and cleaning effect.

[0022] In this embodiment, the cyclone separator 6 uses centrifugal force to separate particulate matter from the exhaust gas. The separated particulate matter is deposited in the bottom collection hopper 7. The detachable collection hopper 7 facilitates regular cleaning of particulate matter, preventing accumulation and blockage that could affect separation efficiency and ensuring long-term stable operation of the equipment. The exhaust gas treated by the cyclone separator 6 is discharged to other treatment equipment through the top output pipe of the cyclone separator 6. The top output pipe discharges the purified exhaust gas, facilitating further treatment or achieving emission standards. The spark arrestor in the conveying pipe 1 can intercept sparks in the exhaust gas, preventing sparks from entering subsequent equipment and causing fires or damaging components. The cleaning component can promptly remove accumulated dust and impurities from the spark arrestor, preventing blockage that could affect the flow of exhaust gas and the spark arrestor effect. The two components work together to ensure the safety and smooth flow of exhaust gas during the conveying process.

[0023] The anti-sparking component consists of multiple sets of wire mesh 20 fixedly connected inside the conveying pipe 1, with the wire mesh 20 evenly distributed inside the conveying pipe 1. A rotating rod 17 is rotatably connected to the wire mesh 20, and the cleaning component consists of multiple sets of scrapers 18 fixedly connected to the outside of the rotating rod 17, with the scrapers 18 in contact with the outside of the wire mesh 20.

[0024] In this embodiment, multiple sets of evenly distributed wire mesh 20 constitute a multi-layered spark barrier. Compared to a single-layer wire mesh 20, the multi-layer design can more effectively intercept sparks in the exhaust gas, significantly reducing the probability of spark penetration and improving fire safety. Furthermore, the even distribution ensures that the exhaust gas passes uniformly through the conveying pipe 1, preventing airflow obstruction or spark leakage due to uneven density of the wire mesh 20 in certain areas. The wire mesh 20 is made of high-temperature and corrosion-resistant materials, capable of withstanding the high temperatures and corrosive substances in the exhaust gas, extending its service life, and making it suitable for the harsh exhaust gas environment in the waste incineration power generation field.

[0025] In this embodiment, the cleaning assembly consisting of the rotating rod 17 and the scraper 18 rotates synchronously with the scraper 18 as the rotating rod 17 rotates. The scraper 18 contacts the outside of the wire mesh 20, which can scrape off the accumulated ash and impurities (such as carbon particles and dust produced by incineration) attached to the surface of the wire mesh 20 in real time, preventing these substances from clogging the mesh openings of the wire mesh 20, ensuring that the exhaust gas can pass through the wire mesh 20 smoothly, and at the same time avoiding the long-term accumulation of impurities from affecting the spark interception effect of the wire mesh 20. The scraper 18 is made of wear-resistant material, which can ensure the scraping effect while reducing wear on the wire mesh 20, balancing cleaning efficiency and equipment protection. In addition, a wire brush can be installed on the side of the scraper 18 close to the wire mesh 20 to clean the dirt inside the openings of the wire mesh 20.

[0026] Additionally, a fixed frame 8 is fixedly connected to the top of the conveying pipe 1, and a motor 9 is fixedly connected to the outside of the fixed frame 8. A first gear 13 is fixedly connected to the output end of the motor 9, and a second gear 16 is fixedly connected to one end of the rotating rod 17. A first rack 10 is provided on the outside of the first gear 13, and a second rack 15 is fixedly connected to the outside of the second gear 16. A slide rod 14 is fixedly connected between the first rack 10 and the second rack 15. The slide rod 14 is made of heat-insulating material, passes through the conveying pipe 1, and is slidably connected to the conveying pipe 1. A slide rail 12 is fixedly connected to the top of the conveying pipe 1, and a slide bar 11 is slidably connected inside the slide rail 12. The slide bar 11 is fixedly connected to the first rack 10.

[0027] The mounting bracket 8 provides a stable foundation for the motor 9, ensuring that the motor 9 will not shift due to vibration during operation and guaranteeing the stability of power transmission. The motor 9, as the power source, drives the first gear 13 to rotate, which in turn moves the first rack 10 meshing with it. The first rack 10, through the slide rod 14, drives the second rack 15 to move synchronously, thereby driving the second gear 16 to rotate. Ultimately, this achieves the rotation of the rotating rod 17 and the scraper 18. The gear and rack transmission structure accurately converts the rotational motion of the motor 9 into the rotational motion of the rotating rod 17, ensuring a stable scraping speed and uniform scraping force for the scraper 18, and preventing incomplete scraping or damage to the wire mesh 20 due to unstable power transmission.

[0028] The heat-insulating slide rod 14 can block the high temperature inside the conveying pipe 1 from being transmitted to the external gear and rack assembly, preventing high temperature damage to components and ensuring the normal operation of the transmission structure. The sliding connection design between the slide rod 14 and the conveying pipe 1 allows the slide rod 14 to move with the rack while ensuring the sealing of the conveying pipe 1 to prevent exhaust gas leakage. The slide rail 12 cooperates with the slide bar 11 to guide the movement of the first rack 10, preventing the rack from deviating during movement, further ensuring transmission accuracy, and ensuring that the cleaning assembly can continuously and stably clean the wire mesh 20, maintaining the spark-proof and exhaust gas conveying effect of the equipment. The bottom of the conveying pipe 1 is provided with an opening, and a bottom cover 19 is detachably and fixedly connected to the opening, making it easy to remove the bottom cover 19 and then clean the dirt inside the conveying pipe 1.

[0029] The usage method of this embodiment is as follows: When using this waste gas purification equipment, first check the connection status of each component to ensure that the conveying pipe 1, the first pipe 3, and the second pipe 5 are tightly connected without leakage, the bottom collection hopper 7 of the cyclone separator 6 is securely installed, and the power supply connection of the motor 9 and the conveying fan 4 is normal. Then start the conveying fan 4. The fan draws waste gas from the conveying pipe 1 through the first pipe 3. The waste gas enters the conical pipe 2 through the inlet pipe and flows evenly into the conveying pipe 1 under the guidance of the conical pipe 2. When the waste gas passes through the conveying pipe 1, the anti-sparking component composed of multiple sets of steel wire mesh 20 inside intercepts sparks in the waste gas to prevent sparks from entering the subsequent cyclone separator 6 and causing safety risks. Simultaneously, motor 9 is started, which drives the first gear 13 to rotate. The first gear 13 drives the first rack 10 to move along the slide bar 11 in the slide rail 12. The first rack 10 drives the second rack 15 to move synchronously through the heat-insulating slide bar 14. The second rack 15 drives the second gear 16 to rotate, which in turn drives the rotating rod 17 and the scraper 18 to rotate. The scraper 18 contacts the outside of the wire mesh 20, scraping away the accumulated dust and impurities attached to the surface of the wire mesh 20 in real time. After being treated to prevent sparks, the exhaust gas enters the cyclone separator 6 through the second pipe 5 under the action of the conveying fan 4. The cyclone separator 6 uses centrifugal force to separate particulate matter in the exhaust gas. The particulate matter is deposited into the bottom collection hopper 7. The purified exhaust gas is discharged from the top output pipe and then enters other treatment equipment, such as a scrubbing tower, for further washing treatment. After the equipment has been running for a period of time, the conveying fan 4 and motor 9 are turned off, the bottom collection hopper 7 of the cyclone separator 6 is removed, and the deposited particulate matter inside is cleaned. After cleaning, the collection hopper 7 is reinstalled. If continued use is required, the above start-up steps can be repeated. The wear of the wire mesh 20 and scraper 18 should be checked regularly to ensure long-term stable operation of the equipment.
