Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment devices, specifically to a self-cleaning waste gas treatment device. Background Technology

[0002] Waste gas treatment mainly refers to the treatment of industrial waste gases generated in industrial sites, such as particulate matter, flue gas, odorous gases, and toxic and harmful gases. Common waste gas purification methods include factory flue gas purification, workshop dust gas purification, organic waste gas purification, waste gas odor purification, acid and alkali waste gas purification, and chemical waste gas purification.

[0003] After continuous operation, existing waste gas treatment devices accumulate a large amount of particulate impurities and chemical pollutants on the surface of the packing components, and the filter screen also traps numerous particles. These impurities accumulate continuously, and due to the lack of an effective self-cleaning mechanism, the pores of the packing components and filter screen become clogged, increasing the resistance to waste gas passage, reducing waste gas treatment efficiency, and decreasing the equipment's processing capacity. Furthermore, the long-term accumulation of impurities on the packing components and filter screen affects their adsorption and filtration performance, shortens their service life, increases equipment maintenance costs and replacement frequency, and negatively impacts the quality of the treated waste gas, failing to meet increasingly stringent environmental emission requirements.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a self-cleaning waste gas treatment device.

[0027] This utility model provides, for example Figure 1-4 The self-cleaning exhaust gas treatment device shown includes a base 1, a treatment tank 2 fixedly connected to the top of the base 1, an exhaust pipe 3 fixedly connected between the base 1 and the treatment tank 2, an air inlet pipe 4 fixedly connected to the side wall of the base 1, one end of the air inlet pipe 4 fixedly connected to the bottom of the side wall of the exhaust pipe 3, an exhaust mesh 5 opened in the pipe wall of the exhaust pipe 3, an annular frame 6 fixedly connected inside the cavity of the treatment tank 2, and a packing element 7 fixedly connected to the side wall of the annular frame 6 through an opening;

[0028] A spray plate device 8 is fixedly connected to the top of the cavity of the treatment tank 2. A water supply pump assembly 9 is fixedly connected to the side wall of the treatment tank 2. One end of the water supply pump assembly 9 is fixedly connected to the input end of the spray plate device 8. A coarse filter screen 10 is fixedly connected to the bottom of the cavity of the treatment tank 2. A support pipe 11 is rotatably connected to the cavity of the annular frame 6. A motor 12 is fixedly connected to the bottom of the exhaust pipe 3. One end of the support pipe 11 is fixedly connected to one end of the motor 12. A pulse cleaning device 13 is fixedly connected to the side wall of the support pipe 11. A power supply mechanism is provided between the side wall of the treatment tank 2 and the support pipe 11. A negative pressure exhaust mechanism is fixedly connected to the top of the treatment tank 2. Multiple drainage holes 14 are opened on the side walls of the treatment tank 2 and the base 1. A drainage valve 15 is fixedly connected to the bottom of the base 14. The base 1 provides stable support for the entire device. The treatment tank 2 serves as the main space for waste gas treatment. The inlet pipe 4 introduces the waste gas, and the exhaust pipe 3 distributes the waste gas evenly through the exhaust mesh 5. The exhaust gas enters the treatment tank 2. The annular frame 6 and packing 7 increase the contact area between the exhaust gas and the treatment medium, improving treatment efficiency. The spray plate device 8, in conjunction with the water supply pump assembly 9, sprays the exhaust gas. The coarse filter 10 filters large particles of impurities. The motor 12 drives the support pipe 11 and the pulse cleaning device 13 to rotate, achieving a self-cleaning function. The power supply mechanism provides power to the pulse cleaning device 13. The negative pressure exhaust mechanism accelerates the flow of exhaust gas and discharges the purified gas. The drain hole 14 and drain valve 15 facilitate the discharge of treated wastewater. Through the coordination of the above structures, the self-cleaning function of the device is effectively realized, preventing the packing 7 and the coarse filter 10 from clogging and ensuring the continuous and stable operation of the device. This solves the problem that existing exhaust gas treatment devices lack self-cleaning function, and that after continuous use, a large amount of dust and impurities accumulate on the surface of the packing and filter screen, making it difficult to self-clean and easily causing clogging.

[0029] In order to provide pulsed airflow to support tube 11, such as Figure 1 , 2 As shown in Figure 4, the power supply mechanism includes a rotating sealing connecting pipe 16, a power supply pipe 17, and a pulse jet system device 18. The top of the annular frame 6 is rotatably connected to the rotating sealing connecting pipe 16, and the bottom of the rotating sealing connecting pipe 16 is rotatably connected to the top of the support pipe 11. The power supply pipe 17 is fixedly connected to the top output end of the rotating sealing connecting pipe 16. The pulse jet system device 18 is fixedly connected to the other end of the side wall of the treatment tank 2. The other end of the power supply pipe 17 passes through the side wall of the treatment tank 2 and is fixedly connected to the output end of the pulse jet system device 18. The rotating sealing connecting pipe 16 is used to achieve a sealed connection when the support pipe 11 rotates. The pulse jet system device 18 provides pulse airflow to the support pipe 11 through the power supply pipe 17, providing cleaning power for the pulse cleaning device 13. This ensures the cleaning effect without affecting the rotation of the support pipe 11, enabling the pulse cleaning device 13 to continuously and effectively clean the packing 7 and the coarse filter screen 10.

[0030] In order to discharge the treated waste gas, such as Figure 1 and 2 As shown, the negative pressure exhaust mechanism includes an air intake chamber 19, a negative pressure fan 20, and a reversing valve 21. The air intake chamber 19 is fixedly connected to the top of the treatment tank 2, and the negative pressure fan 20 is fixedly connected inside the air intake chamber 19. The reversing valve 21 is fixedly connected to the output end of the air intake chamber 19. The negative pressure fan 20 creates negative pressure in the air intake chamber 19, accelerating the upward flow and discharge of the exhaust gas in the treatment tank 2. The reversing valve 21 can be connected to the exhaust gas discharge pipe and the dust discharge pipe during the cleaning process, respectively. The output port can be switched according to the actual situation to facilitate subsequent treatment or discharge. By adjusting the power of the negative pressure fan 20 and the direction of the reversing valve 21, the exhaust gas treatment process can be optimized according to actual needs.

[0031] To facilitate the treatment of exhaust gas in conjunction with the packing element 7, such as Figure 2 and 4 As shown, the spray plate device 8 is a semi-circular hollow body, and the semi-circular surface is fixedly connected to the first compression nozzle 22 through multiple holes. By using the spray plate device 8 with the semi-circular hollow body structure, the first compression nozzle 22 is improved to make the spray liquid evenly cover the cross-section of the filler 7, forming a water film to contact the exhaust gas for treatment. The first compression nozzle 22 increases the spray pressure and dispersion of the spray liquid, and enhances the contact and reaction efficiency with pollutants in the exhaust gas.

[0032] To remove dust and impurities from the surface and interior of the packing element 7, such as Figure 2-4As shown, the pulse cleaning device 13 includes an air supply connection end 23. U-shaped hollow plates 24 are fixedly connected to the top and bottom output ends of the air supply connection end 23. Brush plates 25 are fixedly connected to the top of both ends of the U-shaped hollow plates 24. Second compression nozzles 26 are fixedly connected to the top of the U-shaped hollow plates 24 through multiple holes. The pulse airflow is introduced into the U-shaped hollow plates 24 at both ends by the air supply connection end 23. The brush plates 25 at the top of both ends of the U-shaped hollow plates 24 mechanically clean the surface of the packing component 7 during rotation. The compressed airflow ejected from the second compression nozzles 26 performs pulse jet cleaning on the packing component 7. The combination of the two improves the self-cleaning effect and can effectively remove dust and impurities from the surface and inside of the packing component 7, restoring its processing performance.

[0033] To reduce clogging and extend service life, such as Figure 1 and 4 As shown, both the packing element 7 and the coarse filter screen 10 are provided with a ceramic anti-stick coating. The ceramic anti-stick coating can prevent sticky substances in the exhaust gas from adhering to the surface of the packing element 7 and the coarse filter screen 10, reduce clogging, extend service life, and reduce maintenance costs.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
