Description

Technical Field

[0001] The invention belongs to the technical field of waste gas treatment equipment, and in particular relates to an air filter for environmentally friendly treatment of industrial waste gas. Background Art

[0002] Industrial waste gas refers to the waste gas emitted during the industrial production process. Industrial waste gas contains industrial dust and particulate impurities as well as various volatile harmful gases. The dust and harmful gases in industrial waste gas can cause serious damage to the ecological environment and human health. By treating industrial waste gas, the waste gas can be fully purified to reduce the impact of industrial waste gas on the ecology.

[0003] However, existing air filters for environmental protection of industrial waste gas often have the following problems when used:

[0004] The key link in the process of industrial waste gas purification is to filter and remove industrial dust and impurity particles in the waste gas so as to treat harmful gases in the later stage. When the filter device intercepts dust and particles, fine dust and particles will inevitably adhere to the filter holes of the filter device. After a period of filtration, it is easy to cause the filter device to become clogged, which will not only reduce the filtering effect of the filter device on industrial waste gas, but also increase the subsequent cleaning and maintenance costs of the filter device.

[0005] The centralized treatment of dust and particles in industrial waste gas usually adopts natural sedimentation and direct adsorption. In this way, the treatment rate of dust and particles is slow. However, the content of dust and particles in industrial waste gas is high, and the slow treatment rate of dust and particles will directly affect the purification efficiency of industrial waste gas.

[0006] Catalytic oxidation is generally used to treat harmful gases in industrial waste gas in order to oxidize the harmful gases into organic matter. However, the contact between the harmful gases and the oxidizing catalyst is very limited, resulting in low uniformity in the oxidation treatment of harmful gases in industrial waste gas.

Frame 11, small gear 12 and transfer gear 13, the lifting screw 7 is rotatably connected to the top of the exhaust gas treatment cylinder 3, the lifting slider 8 is threadedly connected to the lifting screw 7, the sliding bracket 9 is fixedly connected to the lifting slider 8, the compression tube 10 is slidably connected to the sliding bracket 9, the sealing air frame 11 is fixedly connected to the end of the compression tube 10, and the sealing air frame 11 is connected to the compression tube 10, and a sealing gasket is provided on the sealing air frame 11, and the sealing air frame 11 is sealed with the outer wall of the outer filter cylinder 4 through the sealing gasket, the small gear 12 is fixedly connected to the lower end of the lifting screw 7, the transfer gear 13 is fixedly connected to the lower end of the support shaft 5, and the transfer gear 13 and the small gear 12 are meshed with each other, and the anti-blocking component also includes a compression cylinder 26, a one-way valve 27, A micro alloy spring 28, a roller 29 and a corrugated slide rail 30, the compression cylinder 26 is sealingly and slidably connected to the outer wall of the compression tube 10, a one-way valve 27 is arranged on the circumferential side wall of the compression cylinder 26, the one-way valve 27 includes a cross bracket and a soft rubber gasket, the cross bracket can limit the deformation of the soft rubber gasket, so that the gas can only pass into the compression cylinder 26 from the outside, one end of the micro alloy spring 28 is fixedly connected to the end of the compression tube 10, the other end of the micro alloy spring 28 is fixedly connected to the inner bottom surface of the compression cylinder 26, the roller 29 is fixedly connected to the end of the compression cylinder 26, the corrugated slide rail 30 is fixedly connected to the inner wall of the exhaust gas treatment cylinder 3, the roller 29 matches the corrugated slide rail 30, and a servo motor 35 is fixedly connected to the top of the exhaust gas treatment cylinder 3, and the output end of the servo motor 35 is fixedly connected to the upper end of the lifting screw 7 through a coupling;

[0035] like Figure 2 and Figure 3 As shown, a limit slide bar is fixedly connected to the inner wall of the exhaust gas treatment tube 3, a limit block is slidably connected to the limit slide bar, the limit block is fixedly connected to the lifting slider 8 through a connecting rod, and the lifting movement of the lifting slider 8 is fully limited by the limit block, so that the operation stability of the lifting slider 8 and the roller 29 can be ensured;

[0036] The servo motor 35 drives the lifting screw 7 and the small gear 12 at the lower end to rotate, and the meshing of the small gear 12 and the transfer gear 13 can drive the support shaft 5 and the inner filter cartridge 6 to rotate, so that the inner filter cartridge 6 can rotate in the outer filter cartridge 4. Since the number of outer filter holes on the outer filter cartridge 4 and the number of inner filter holes on the inner filter cartridge 6 are the same, during the rotation of the inner filter cartridge 6, the outer filter cartridge 4 can form a sealing effect for a certain period of time, thereby increasing the retention time of industrial waste gas in the inner filter cartridge 6, so as to improve the removal effect of dust and particulate impurities in the industrial waste gas. When the lifting screw 7 rotates, it can drive the lifting slider 8 to move, so that the sealing air frame 11 can move synchronously. Since the outer filter holes and the inner filter holes have a certain distance in the longitudinal direction, the sealing air frame 11 slides relative to the outer wall of the outer filter cartridge 4. When the filter element 20 is in motion, there will be a relatively sealed environment. At this time, the compression cylinder 26 can be driven to expand and contract relative to the compression tube 10 by the matching and fitting sliding of the roller 29 relative to the corrugated slide rail 30, and the setting of the one-way valve 27 on the compression cylinder 26 can make the sealed air-filling frame 11, the compression tube 10 and the compression cylinder 26 gradually pressurized due to the absorption of the industrial waste gas from which the dust and particulate impurities in the waste gas treatment cylinder 3 have been removed. When the inner filter cylinder 6 is rotated until the outer filter hole and the inner filter hole are connected, the pressurized sealed air-filling frame 11 can be used to fill the inner filter cylinder 6 with air, and the pressurized exhaust gas can be used to impact and eliminate the dust and particulate impurities attached to the outer filter hole and the inner filter hole, so as to avoid clogging of the filter device. This can not only improve the filtering effect of the filter device on industrial waste gas, but also effectively reduce the subsequent cleaning and maintenance costs of the filter device.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 8 As shown, a high-efficiency adsorption component is arranged inside the inner filter cartridge 6, and the high-efficiency adsorption component includes a plurality of strip rails 14, a plurality of strip straight plates 15, a plurality of inclined adsorption plates 16, a plurality of paddles 17, a plurality of disassembly through holes 18 and an annular closed cover plate 19. The plurality of strip rails 14 are arranged on the inner wall of the inner filter cartridge 6, the plurality of strip straight plates 15 are respectively slidably connected in the plurality of strip rails 14, the plurality of inclined adsorption plates 16 are respectively fixedly connected to the lower ends of the plurality of strip straight plates 15, the plurality of paddles 17 are respectively fixedly connected to the upper ends of the plurality of strip straight plates 15, the plurality of disassembly through holes 18 are opened at the top of the exhaust gas treatment cartridge 3, the annular closed cover plate 19 is arranged at the plurality of disassembly through holes 18 on the exhaust gas treatment cartridge 3, the annular closed cover plate 19 is provided with a plurality of silicone pads, the plurality of silicone pads are matched with the plurality of disassembly through holes 18, and the inclined adsorption plate 16 is an activated carbon adsorption plate;

[0038] After the industrial waste gas enters the inner filter cartridge 6, it will impact the bottom of the inner filter cartridge 6 and rebound. At this time, the dust and particulate impurities in the industrial waste gas rebounding from the bottom of the inner filter cartridge 6 can be fully adsorbed by a number of inclined adsorption plates 16. At the same time, the sealing air frame 11 can pass pressurized waste gas into the inner filter cartridge 6, so that the rebound degree of the industrial waste gas in the inner filter cartridge 6 is higher, and the adsorption effect of the inclined adsorption plates 16 on dust and particulate impurities is further improved, thereby improving the adsorption treatment rate of dust and particulate impurities and the purification treatment efficiency of industrial waste gas, and a number of inclined adsorption plates 16 can be disassembled and removed through the disassembly through hole 18 at the top of the waste gas treatment cartridge 3, so as to replace and maintain a number of inclined adsorption plates 16.

[0039] like Figure 1 and Figure 7 As shown, a linkage oxidation treatment component is arranged outside the exhaust gas treatment cylinder 3, and the linkage oxidation treatment component includes an oxidation cylinder 20, a transfer tube 21, a first rotating rod 22, a supporting disc 23, a spoiler rod 24, a plurality of catalyst sheets 25 and synchronous operation components. The oxidation cylinder 20 is fixedly connected to the support frame 2 through a fixed bracket, the transfer tube 21 is arranged at the lower end of the side wall of the exhaust gas treatment cylinder 3, the transfer tube 21 is connected to the oxidation cylinder 20, the first rotating rod 22 is rotatably connected to the top of the oxidation cylinder 20, the supporting disc 23 is fixedly connected to the lower end of the first rotating rod 22, the spoiler rod 24 is fixedly connected to the bottom of the supporting disc 23, a plurality of catalyst sheets 25 are evenly arranged on the inner wall of the oxidation cylinder 20, and the synchronous operation components It is arranged on the outer wall of the exhaust gas treatment tube 3, and the synchronous operation components include a second rotating rod 31, two synchronous wheels 32, a synchronous belt 33 and two transmission gears 34. The second rotating rod 31 is rotatably connected to the outer wall of the exhaust gas treatment tube 3 through a rotating bracket. The two synchronous wheels 32 are respectively fixedly connected to the lifting screw 7 and the upper end of the second rotating rod 31. The two synchronous wheels 32 are connected by a synchronous belt 33. The two transmission gears 34 are respectively fixedly connected to the lower end of the second rotating rod 31 and the upper end of the first rotating rod 22, and the two transmission gears 34 are meshed with each other. An air inlet pipe 36 is arranged on the top of the exhaust gas treatment tube 3, and an exhaust pipe 37 is fixedly connected to the base 1. The oxidation tube 20 is connected to the exhaust pipe 37 through a connecting pipe;

[0040] When the servo motor 35 drives the lifting screw 7 to rotate, the second rotating rod 31 can be driven to rotate through the synchronous wheel 32 at the upper end of the lifting screw 7 and the synchronous wheel 32 at the upper end of the second rotating rod 31 and the synchronous belt 33, and then the first rotating rod 22 is driven to rotate through the engagement of the transmission gear 34 at the lower end of the second rotating rod 31 and the transmission gear 34 at the upper end of the first rotating rod 22, so that the supporting disk 23 and the spoiler rod 24 at the lower end of the first rotating rod 22 start to rotate. Through the rapid rotation of the spoiler rod 24, the harmful gas can be evenly and fully contacted with the several catalyst sheets 25 inside the oxidation cylinder 20, which not only improves the linkage degree of the oxidation treatment of the device, but also can effectively improve the oxidation treatment uniformity and oxidation treatment effect of the harmful gas in the industrial waste gas.

[0041] The working principle of the present invention is as follows:

[0042] When in use, first, the industrial waste gas is passed into the inner filter cartridge 6 in the waste gas treatment cartridge 3 through the air inlet pipe 36, and the servo motor 35 is started. The lifting screw 7 and the small gear 12 at the lower end thereof are driven to rotate by the servo motor 35. The engagement of the small gear 12 with the transfer gear 13 can drive the support shaft 5 and the inner filter cartridge 6 to rotate, so that the inner filter cartridge 6 can rotate in the outer filter cartridge 4. Since the number of outer filter holes on the outer filter cartridge 4 and the number of inner filter holes on the inner filter cartridge 6 are the same, during the rotation of the inner filter cartridge 6, the outer filter cartridge 4 can form a sealing effect for a certain period of time, thereby increasing the retention time of the industrial waste gas in the inner filter cartridge 6, so as to improve the removal effect of dust and particulate impurities in the industrial waste gas. When the lifting screw 7 rotates, the lifting slider 8 can be driven to move, so that the sealing air frame 11 can move synchronously. Since the outer filter holes and the inner filter holes have a certain longitudinal direction, The sealing air-injection frame 11 is relatively sealed when it slides relative to the outer wall of the outer filter cartridge 4. At this time, the compression cartridge 26 can be driven to expand and contract relative to the compression tube 10 by the matching and fitting sliding of the roller 29 relative to the corrugated slide rail 30. The one-way valve 27 on the compression cartridge 26 can be used to gradually increase the pressure of the sealing air-injection frame 11, the compression tube 10 and the compression cartridge 26 due to the absorption of the industrial waste gas from which the dust and particulate impurities in the waste gas treatment cartridge 3 have been removed. When the inner filter cartridge 6 rotates until the outer filter hole and the inner filter hole are connected, the pressurized sealing air-injection frame 11 can be used to inject air into the inner filter cartridge 6, and the pressurized waste gas can be used to impact and eliminate the dust and particulate impurities attached to the outer filter hole and the inner filter hole, so as to avoid the problem of clogging of the filter device. This can not only improve the filtering effect of the filter device on the industrial waste gas, but also effectively reduce the subsequent cleaning and maintenance costs of the filter device.

[0043] After the industrial waste gas passes into the inner filter cartridge 6 through the air inlet pipe 36, the industrial waste gas will impact the bottom of the inner filter cartridge 6 and rebound. At this time, the dust and particulate impurities in the industrial waste gas rebounding from the bottom of the inner filter cartridge 6 can be fully adsorbed by the inclined adsorption plate 16. At the same time, the sealing air frame 11 can pass the pressurized waste gas into the inner filter cartridge 6, so that the rebound degree of the industrial waste gas in the inner filter cartridge 6 is higher, and the adsorption effect of the inclined adsorption plate 16 on dust and particulate impurities is further improved, thereby improving the adsorption treatment rate of dust and particulate impurities and the purification treatment efficiency of industrial waste gas, and the inclined adsorption plate 16 can be disassembled and removed through the disassembly through hole 18 at the top of the waste gas treatment cartridge 3, so as to replace and maintain the inclined adsorption plate 16;

[0044] In the process of removing dust and particulate impurities in industrial waste gas, that is, when the servo motor 35 drives the lifting screw 7 to rotate, the second rotating rod 31 can be driven to rotate by the synchronous wheel 32 at the upper end of the lifting screw 7 and the synchronous wheel 32 at the upper end of the second rotating rod 31 and the synchronous belt 33, and then the first rotating rod 22 is driven to rotate by the engagement of the transmission gear 34 at the lower end of the second rotating rod 31 and the transmission gear 34 at the upper end of the first rotating rod 22, so that the supporting disk 23 and the spoiler rod 24 at the lower end of the first rotating rod 22 start to rotate, and the rapid rotation of the spoiler rod 24 can make the harmful gas and the catalyst sheet 25 inside the oxidation cylinder 20 evenly and fully contact, which not only improves the linkage degree of the oxidation treatment of the device, but also can effectively improve the oxidation treatment uniformity and oxidation treatment effect of the harmful gas in the industrial waste gas.
