Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and more specifically, to a highly efficient industrial waste gas purification and treatment device. Background Technology

[0002] Industrial waste gas refers to the collective term for various gaseous pollutants generated during industrial production processes. It typically contains a variety of harmful substances, such as particulate matter, volatile organic compounds, acidic gases, heavy metals, and some specific chemical substances. The composition and concentration of these waste gases vary significantly depending on the industry and production process. For example, the chemical industry may produce waste gas containing complex organic compounds, while the steel industry mainly produces particulate matter and acidic gases. The emission of industrial waste gas not only pollutes the environment, exacerbating problems such as smog and acid rain, but may also harm human health, causing respiratory diseases and potentially leading to cancer. Therefore, the treatment of industrial waste gas is a crucial aspect of environmental protection, usually requiring the use of various purification technologies, such as filtration, adsorption, catalytic combustion, and chemical absorption, to ensure compliance with emission standards and reduce negative impacts on the environment and human health.

[0003] The first step in industrial waste gas treatment is filtration, which removes large particulate impurities from the waste gas through filter screens. This reduces the processing load on subsequent purification equipment, improves purification efficiency, and prevents subsequent purification equipment from being clogged by large particulate impurities, thus protecting the equipment.

[0004] However, most industrial waste gases also contain sticky particles, which adhere to the filter screen, causing filter screen blockage and reducing waste gas treatment efficiency. Furthermore, existing filter screen cleaning methods such as backflushing are also difficult to remove sticky particles from the filter screen, making the cleaning of sticky particles quite difficult.

[0035] Reference Figures 1 to 6 In one embodiment of this application, a high-efficiency industrial waste gas purification and treatment device includes a tank 1, a drive mechanism, and a cleaning mechanism.

[0036] An air inlet pipe 2 is connected to the side wall of the tank 1. An exhaust port 3 is opened at the upper end of the tank 1. Cleaning liquid is placed at the bottom of the tank 1. A lifting ring 4 is fixedly connected to the top wall of the tank 1. A filter cylinder 5 is rotatably connected to the lifting ring 4. The upper end of the filter cylinder 5 is connected to the exhaust port 3. The lower end of the filter cylinder 5 is immersed in the cleaning liquid. Multiple first openings 6 are opened on the filter cylinder 5. A first filter screen 7 is fixedly connected to the filter cylinder 5. The first filter screen 7 covers the multiple first openings 6.

[0037] like Figures 1 to 3 The exhaust gas enters the tank 1 through the inlet pipe 2. Since the lower end of the filter cartridge 5 is immersed in the cleaning liquid, the exhaust gas can only pass through the first filter screen 7 and the first port 6 to enter the filter cartridge 5. The first filter screen 7 filters out large particulate impurities in the exhaust gas, but the sticky particles in the exhaust gas will adhere to the first filter screen 7. The filtered exhaust gas is discharged from the tank 1 through the exhaust port 3.

[0038] The drive mechanism is installed on the tank 1, and the drive mechanism is used to drive the filter cartridge 5 to rotate.

[0039] The cleaning mechanism is installed on the tank body 1 and is used to clean the first filter screen 7. The cleaning mechanism includes a cleaning cover 8, a vertical pipe 9, a roller brush 11, a water supply pipe 12, a first water pump 13, a vertical shaft 14, and a first motor 15. The cleaning cover 8 is fixedly connected to the inner wall of the tank body 1. The vertical pipe 9 is rotatably connected to the cleaning cover 8. The vertical pipe 9 has multiple water outlet holes 10. The roller brush 11 is fixedly sleeved on the vertical pipe 9. The roller brush 11 rubs against the first filter screen 7. One end of the vertical pipe 9 is connected to the water supply pipe 12 through a rotary joint. The end of the water supply pipe 12 away from the vertical pipe 9 is connected to the outlet of the first water pump 13. The first water pump 13 is installed on the tank body 1. The inlet of the first water pump 13 is connected to the bottom of the tank body 1. The other end of the vertical pipe 9 is fixedly connected to the vertical shaft 14. The vertical shaft 14 is connected to the output shaft of the first motor 15 through a coupling. The first motor 15 is installed on the tank body 1.

[0040] like Figure 2 , Figure 5 and Figure 6 The first water pump 13 can extract the cleaning fluid from the bottom of the tank 1 and pump the cleaning fluid into the vertical pipe 9 through the water supply pipe 12. The cleaning fluid in the vertical pipe 9 flows through multiple water outlets 10 to the roller brush 11.

[0041] The first motor 15 can drive the vertical tube 9 to rotate via the vertical shaft 14. The vertical tube 9 drives the roller brush 11 on it to rotate. The rotating roller brush 11, together with the cleaning liquid on it, can brush and wash the first filter screen 7.

[0042] Then, the filter cartridge 5 is driven to rotate by the drive mechanism, and the filter cartridge 5 drives the first filter screen 7 on it to rotate. The roller brush 11 can continuously brush the entire first filter screen 7, thereby removing large particles and sticky particles from the first filter screen 7, preventing the first filter screen 7 from being blocked, and keeping the first filter screen 7 unobstructed. Compared with the existing technology, it can effectively improve the treatment efficiency of exhaust gas.

[0043] In a preferred embodiment of this application, the cleaning mechanism further includes a water absorption assembly, which includes multiple support rollers 16, a water absorption belt 17, and a squeezing roller 18. The multiple support rollers 16 are rotatably connected to the cleaning cover 8. The multiple support rollers 16 are all fitted with a water absorption belt 17, which is made of water-absorbing material. The multiple support rollers 16 are connected by transmission through the water absorption belt 17. The water absorption belt 17 abuts against the first filter screen 7. A squeezing roller 18 is provided on one side of the water absorption belt 17. The squeezing roller 18 is rotatably connected to the cleaning cover 8. The squeezing roller 18 cooperates with the support rollers 16 to squeeze the water absorption belt 17.

[0044] like Figure 4 and Figure 5The water-absorbing belt 17 comes into contact with the first filter screen 7. The water-absorbing belt 17 can absorb the cleaning liquid remaining on the first filter screen 7, keeping the first filter screen 7 dry and facilitating filtration.

[0045] Furthermore, the rotating first filter screen 7 can drive the water absorption belt 17 to rotate. When the water absorption belt 17, after absorbing the cleaning liquid, rotates between the squeeze roller 18 and the support roller 16, the cleaning liquid in the water absorption belt 17 will be squeezed out, so that the water absorption belt 17 can continuously absorb the cleaning liquid remaining on the first filter screen 7.

[0046] In a preferred embodiment of this application, the lower end of the cleaning cover 8 has a plurality of drainage grooves 19, such as... Figure 5 Multiple drainage channels 19 facilitate the discharge of cleaning fluid from the roller brush 11 and the absorbent belt 17 from the cleaning hood 8.

[0047] In a preferred embodiment of this application, the driving mechanism includes a ring rail 20, a slider 21, an internal gear ring 22, a gear 23, and a second motor 24. The ring rail 20 is fixedly connected to the lifting ring 4. Multiple sliders 21 are slidably connected to the ring rail 20. Each slider 21 is fixedly connected to the filter cartridge 5. An internal gear ring 22 is fixedly connected to the filter cartridge 5. A gear 23 is meshed on the internal gear ring 22. The gear 23 is fixedly connected to the output shaft of the second motor 24. The second motor 24 is mounted on the tank body 1.

[0048] like Figure 2 and Figure 3 The ring rail 20 supports the filter cartridge 5 through multiple sliders 21. The second motor 24 drives the gear 23 to rotate, and the gear 23 can drive the filter cartridge 5 to rotate along the ring rail 20 through the meshing internal gear ring 22.

[0049] In a preferred embodiment of this application, a sealing element is provided between the upper end of the filter cartridge 5 and the top wall of the tank 1, such as... Figure 2 The sealing element ensures the airtightness between the upper end of the filter cartridge 5 and the top wall of the tank 1.

[0050] In a preferred embodiment of this application, a retaining ring 25 is fixedly connected to the bottom of the tank 1, the upper end of the retaining ring 25 is higher than the liquid level of the cleaning fluid, a plurality of second openings 26 are opened on the retaining ring 25, and a second filter screen 27 is fixedly connected to the retaining ring 25, the second filter screen 27 covers the plurality of second openings 26.

[0051] like Figure 2 and Figure 3The cleaning fluid on the roller brush 11 and the absorbent belt 17 will fall down to the inside of the baffle ring 25. The cleaning fluid inside the baffle ring 25 can pass through the second filter screen 27 and the second port 26 to the outside of the baffle ring 25. The second filter screen 27 can intercept and filter impurities in the cleaning fluid. The cleaning fluid flowing to the outside of the baffle ring 25 is relatively clean, so that the first water pump 13 always draws relatively clean cleaning fluid, which has a better cleaning effect on the first filter screen 7 and can save the use of cleaning fluid.

[0052] In a preferred embodiment of this application, a plurality of scrapers 28 are fixedly connected to the lower end of the filter cartridge 5, and the plurality of scrapers 28 rub against the second filter screen 27.

[0053] like Figure 4 The filter cartridge 5 can drive multiple scrapers 28 to rotate, and the multiple scrapers 28 can scrape off the impurities on the second filter screen 27, preventing the second filter screen 27 from being blocked by impurities.

[0054] In a preferred embodiment of this application, the lower end of the tank 1 is connected to a collection hopper 29, and a valve is installed on the outlet of the collection hopper 29;

[0055] like Figure 2 The impurities scraped off the second filter screen 27 will fall into the collection hopper 29. By controlling the valve on the outlet of the collection hopper 29, the impurities in the collection hopper 29 can be discharged when needed.

[0056] As a preferred embodiment of this application, a second water pump 30 is installed on the tank 1. The inlet of the second water pump 30 is connected to the bottom of the tank 1. A delivery pipe 31 is connected to the outlet of the second water pump 30. One end of the delivery pipe 31 away from the second water pump 30 passes through the exhaust pipe 32 and is connected to a nozzle 33. One end of the exhaust pipe 32 is connected to the exhaust port 3.

[0057] like Figure 2 The second water pump 30 can draw out the relatively clean cleaning liquid from the outside of the baffle ring 25 and pump the cleaning liquid to the nozzle 33 through the delivery pipe 31. The cleaning liquid sprayed from the nozzle 33 sprays the filtered exhaust gas, thereby further purifying the exhaust gas. The purified exhaust gas is discharged through the upper end of the exhaust pipe 32 and enters the subsequent purification equipment.

[0058] Under the restriction of the exhaust pipe 32, the cleaning fluid sprayed from the nozzle 33 will not spray onto the first filter screen 7, and the sprayed cleaning fluid will fall onto the inside of the retaining ring 25.

[0059] As a preferred embodiment of this application, the tank 1 is connected to a water supply pipe 34, and a liquid level sensor and a turbidity sensor can be installed at the bottom of the tank 1 to monitor the liquid level and turbidity of the cleaning fluid inside the tank 1, and then add new cleaning fluid to the tank 1 through the water supply pipe 34 when needed.

[0060] Working principle: The first water pump 13 can draw the cleaning liquid from the bottom of the tank 1 and pump it into the vertical pipe 9 through the water supply pipe 12. The cleaning liquid in the vertical pipe 9 flows through multiple water outlets 10 to the roller brush 11.

[0061] The first motor 15 can drive the vertical tube 9 to rotate via the vertical shaft 14. The vertical tube 9 drives the roller brush 11 on it to rotate. The rotating roller brush 11, together with the cleaning liquid on it, can brush and wash the first filter screen 7.

[0062] Then, the filter cylinder 5 is driven to rotate by the drive mechanism, and the filter cylinder 5 drives the first filter screen 7 on it to rotate. The roller brush 11 can then continuously brush the entire first filter screen 7, thereby removing large particles and sticky particles from the first filter screen 7.
