[0002] During the processing of pepper rings, the raw material reaction generates various complex waste gases, such as those containing volatile organic compounds, acidic gases, and odorous substances. Untreated emissions will severely pollute the air and harm the environment. Traditional single-stage purification methods are insufficient to comprehensively and efficiently remove all types of pollutants. Multi-stage waste gas purification equipment, on the other hand, typically incorporates multiple processes to reduce pollutant levels and eliminate odors. It boasts high purification efficiency and excellent results, meeting environmental protection requirements and the needs of sustainable industrial development, ensuring that waste gas emissions from the processing process meet standards.

[0003] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. Currently common exhaust gas purification equipment usually adopts an integrated design with a relatively simple structure, which is not convenient for high-quality and thorough screening and filtration of particulate impurities in exhaust gas, resulting in incomplete gas purification. It usually requires additional circulating filtration and purification operations, which reduces operating efficiency and increases operating costs; 2. Currently common exhaust gas purification equipment does not facilitate easy and convenient disassembly and replacement of the filter layer for subsequent filter layer cleaning operations. It usually requires laborious, tedious, and complex disassembly and splicing operations, which increases labor costs and has poor practicality. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a multi-stage waste gas purification device, including a housing 1, several legs 2 installed at the bottom of the housing 1, an air inlet 3 installed on one side of the housing 1, a water outlet 4 installed at the bottom end of one side of the housing 1, a spray chamber 5 opened at one end inside the housing 1, a spray assembly 6 installed at the top of the inner wall of the spray chamber 5, one end of an air supply pipe 7 installed at the middle of one end of the upper surface of the housing 1, a fan 8 installed at the other end of the air supply pipe 7, a first air outlet pipe 9 installed on one side of the fan 8, and a section of the housing 1 located away from the spray chamber 5. The chamber 10 is provided at one end. Several grooves 11 are provided on both sides of the inner wall of the chamber 10. Multi-stage purification components 12 are slidably connected inside the grooves 11. One end of the air guide pipe 13 is installed on the side of the housing 1 away from the air inlet 3. The other end of the air guide pipe 13 is installed with a box 14. A support column 15 is installed at the bottom of the box 14. An inspection door 16 is hinged to one side of the box 14. A door handle 17 is installed on one side of the inspection door 16. A second air outlet pipe 18 is installed on the top of the box 14. A control valve 19 is installed at one end of the second air outlet pipe 18.

[0023] The spray assembly 6 includes a water collection frame 601 that is movably mounted on the top of the inner wall of the spray chamber 5. Several atomizing nozzles 602 are mounted on the bottom of the water collection frame 601. One end of a water supply pipe 603 is mounted on the top of the water collection frame 601. A water pump 604 is mounted on the other end of the water supply pipe 603. A water inlet pipe 605 is mounted on the top of the water pump 604.

[0024] The multi-stage purification assembly 12 includes a slide rail 1201 that is slidably connected to the inside of the slide 11. A multi-stage filter frame 1202 is installed on one side of the slide rail 1201, and a handle 1203 is installed on the top of the multi-stage filter frame 1202.

[0025] In this embodiment, as Figure 1 As shown, the legs 2 are symmetrically distributed about the horizontal centerline of the housing 1, and the support column 15 is also symmetrically distributed about the horizontal centerline of the housing 14. The symmetrical layout design can significantly improve the stability and balance of the entire equipment, distribute the load evenly to each support point, reduce the risk of deformation or tilting caused by uneven stress on the structure, help enhance durability and safety, and extend the service life of the equipment.

[0026] In this embodiment, as Figure 2 As shown, the atomizing nozzles 602 are distributed in a ring at equal intervals at the bottom of the water collection frame 601. The ring-shaped and equally spaced layout design allows the nozzles to evenly spray atomized water mist into the exhaust gas flow, effectively increasing the contact area between the water mist and the exhaust gas, thereby fully degrading and removing larger particulate impurities in the exhaust gas, preventing excessive accumulation of impurities in local areas, and helping to improve the exhaust gas treatment effect.

[0027] In this embodiment, as Figure 3 As shown, the multi-stage filter frame 1202 forms a lifting structure with the handle 1203 and the slide rail 1201. The lifting structure design allows the multi-stage filter frame 1202 and the internal multi-stage filter plates to be easily, smoothly and conveniently slid out by lifting the handle 1203, without the need for laborious, tedious and complicated disassembly and assembly operations, which helps to efficiently carry out subsequent filter plate cleaning operations and reduces labor costs.

[0028] In this embodiment, as Figure 4 As shown, ultraviolet lamps are installed on both sides and the bottom of the inner wall of the box 14.

[0029] In this embodiment, as Figure 3 As shown, the multi-stage filter frame 1202 is equipped with a moisture-proof filter plate, an adsorption filter plate, and an activated carbon filter plate. It can filter and purify harmful substances in the exhaust gas layer by layer, effectively remove moisture from the exhaust gas, and prevent moisture from interfering with the performance of subsequent filter plates. Through this multi-level, step-by-step filtration design, pollutants in the exhaust gas are efficiently removed, improving the purification effect, extending the service life of the equipment, and ensuring the high efficiency and stability of the exhaust gas treatment system.

[0030] In this embodiment, as Figure 4 As shown, the inspection door 16 is connected to the housing 14 via the door handle 17 to form an opening and closing structure. The design of the opening and closing structure allows the inspection door 16 to be opened quickly and conveniently by pulling the door handle 17, which helps to carry out the maintenance, replacement and inspection of the internal ultraviolet lamps efficiently. At the same time, it facilitates the cleaning of the inner wall of the housing 14 and avoids complicated disassembly and assembly operations.

[0031] The usage method and advantages of this utility model: The working process of this multi-stage exhaust gas purification equipment is as follows:

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, firstly, the operator injects the exhaust gas into the spray chamber 5 of the housing 1 through the air inlet 3, and simultaneously starts the water pump 604, which drives the atomizing nozzle 602 to spray out a special degradation water mist, carrying away larger particulate impurities inside the exhaust gas. As the water mist gradually accumulates and deposits at the bottom of the inner wall of the spray chamber 5, forming waste liquid, the outlet 4 is opened to discharge the waste liquid. Then, the fan 8 is started, which drives the preliminarily degraded exhaust gas into the purification chamber 10. Under the multi-stage filtration of the moisture-blocking filter plate, adsorption filter plate, and activated carbon filter plate set in the purification chamber 10, the exhaust gas can be fully dried and purified. Gas is injected into the chamber 14 through the air duct 13. At this time, multiple ultraviolet lamps inside the chamber 14 are activated to sterilize the exhaust gas, effectively improving the purification quality. Finally, the purified exhaust gas can be directly discharged by adjusting the control valve 19. After the purification operation is completed, the filter treatment layer inside the multi-stage filter frame 1202 can be easily and conveniently removed by pulling the handle 1203, which helps to efficiently disassemble, clean and maintain the filter plates. At the same time, the door handle 17 can be pulled to quickly open the inspection door 16, which facilitates the cleaning of the interior and also helps to efficiently inspect and maintain the ultraviolet lamps.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
