Description

Technical Field

[0001] This utility model relates to the field of VOCs waste gas treatment technology, and in particular to a tank-type VOCs waste gas treatment device. Background Technology

[0002] In the current production process of PVC wallpaper, raw and auxiliary materials such as inks, media, plasticizers, and PVC resin are often used. Most of these raw and auxiliary materials are volatile and will enter the air in the form of volatile organic compounds (VOCs). VOCs refer to organic compounds that have high saturated vapor pressure, low boiling point, small molecular weight under standard conditions, and are easily volatilized at room temperature. These substances are one of the main air pollutants. VOCs do not refer to a specific pollutant, but rather to a collective term for a class of organic compounds with similar physicochemical properties.

[0003] However, when the above-mentioned structure is used in a tank-type VOCs waste gas treatment device, the waste gas produced by different production methods is different, so the substances contained in the waste gas are also different. When treating the gas, it is necessary to treat the particulate matter in the waste gas. The treatment method is different for different waste gas compositions, and the reaction with the gas is also different. Therefore, it is necessary to improve the efficiency during mixing to make the reaction more uniform. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a tank-type VOCs waste gas treatment device. When treating waste gas, the waste gas produced by different production methods is different, so the substances contained in the waste gas are also different. When treating the gas, it is necessary to treat the particles in the waste gas. The treatment method is different for different waste gas compositions, and the reaction method with the gas is also different. Therefore, it is necessary to improve the efficiency during mixing to make the reaction more uniform.

[0005] To achieve the above objectives, a tank-type VOCs waste gas treatment device is provided, comprising a tower body, a pump body installed on the outer wall of the tower body, and an air inlet pipe connected to one side of the pump body. A limiting groove is formed inside the outer wall of the air inlet pipe, and a telescopic rod is installed inside the limiting groove. A limiting block is fixedly installed on one side of the telescopic rod, and a telescopic spring is fixedly connected to one side of the limiting block. The telescopic spring is movably sleeved on the outer wall of the telescopic rod, and the other side of the telescopic spring is installed inside the limiting groove. An installation ring is movably sleeved inside the limiting groove, and a filter screen is fixedly installed on the inner wall of the installation ring. The installation ring has slots on its upper and lower sides. An air outlet pipe is installed on one side of the tower body.

[0006] By pushing the mounting ring into the limiting groove, the mounting ring pushes the limiting block to slide into the limiting groove. When the mounting ring is fully embedded in the limiting groove, the extension and contraction of the telescopic spring pushes the limiting block into the slot, thus limiting the installation of the mounting ring. The sealing block is also embedded in the slot to seal the upper and lower connection of the mounting ring, preventing leakage when filtering dust through the filter screen. The filter screen can filter the exhaust gas, making subsequent treatment more efficient. The filter screen can be removed by pushing and pulling, making installation and disassembly more convenient and also facilitating cleaning of the filter screen.

[0007] According to the aforementioned tank-type VOCs waste gas treatment device, a sealing block is fixedly embedded and connected to one side of the limiting block.

[0008] According to the aforementioned tank-type VOCs waste gas treatment device, the inner wall of the limiting groove is provided with a sliding groove, and a slider is movably sleeved inside the sliding groove, and the slider is movably sleeved inside the sliding groove.

[0009] According to the aforementioned tank-type VOCs waste gas treatment device, a handle is fixedly installed on one side of the mounting ring.

[0010] According to the aforementioned tank-type VOCs waste gas treatment device, a motor is installed at the top of the tower body, and a rotating rod is fixedly installed at the bottom of the motor. A first gear is fixedly installed on one side of the rotating rod, and a second gear is meshed with the first gear. The second gear is fixedly installed on the outer wall of the screw, and a threaded block is threadedly connected to the surface of the screw. A connecting ring is fixedly connected to one side of the threaded block, and a through hole is opened in the inner wall of the connecting ring. A feed pipe is fixedly installed on one side of the connecting ring.

[0011] According to the aforementioned tank-type VOCs waste gas treatment device, the inner wall of the tower is provided with a groove, and a threaded block is movably sleeved inside the groove.

[0012] According to the aforementioned tank-type VOCs waste gas treatment device, regulating valves are installed on the outer walls of the inlet pipe, outlet pipe, and feed pipe.

[0013] The motor drives the rotating rod to rotate, which in turn drives the second gear to rotate through the first gear. This causes the threaded block to move up and down on the screw surface, which in turn causes the connecting ring to move up and down. When the additive flows into the feed pipe, the liquid in the connecting ring is sprayed into the tower body through the through hole. The up and down movement of the spraying mechanism allows for more even spraying, enabling the additive to mix and react more evenly with the waste gas, thereby improving the efficiency of waste gas treatment.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figures 1 to 5This utility model discloses a tank-type VOCs waste gas treatment device, including a tower body 1, a pump body 2 installed on the outer wall of the tower body 1, and an air inlet pipe 3 connected to one side of the pump body 2. A limiting groove 4 is opened inside the outer wall of the air inlet pipe 3, and a telescopic rod 5 is installed inside the limiting groove 4. A limiting block 6 is fixedly installed on one side of the telescopic rod 5, and a telescopic spring 8 is fixedly connected to one side of the limiting block 6. The telescopic spring 8 is movably sleeved on the outer wall of the telescopic rod 5, and the other side of the telescopic spring 8 is installed inside the limiting groove 4. An installation ring 11 is movably sleeved inside the limiting groove 4, and a filter screen 12 is fixedly installed on the inner wall of the installation ring 11. The installation ring 11 has slots 13 on the top and bottom. An air outlet pipe 15 is installed on one side of the tower body 1. By pushing the mounting ring 11 to slide into the limiting groove 4, the mounting ring 11 pushes the limiting block 6 to slide into the limiting groove 4. When the mounting ring 11 is fully embedded in the limiting groove 4, the extension and retraction of the telescopic spring 8 pushes the limiting block 6 to be embedded in the slot 13, thereby limiting the installation of the mounting ring 11. The sealing block 7 is embedded in the slot 13 to seal the upper and lower connection of the mounting ring 11, preventing leakage when filtering dust through the filter screen 12.

[0025] A sealing block 7 is fixedly embedded on one side of the limiting block 6. The sealing block 7 seals the connection between the upper and lower parts of the mounting ring 11.

[0026] The inner wall of the limiting groove 4 is provided with a sliding groove 9, and a slider 10 is movably sleeved inside the sliding groove 9. When the limiting block 6 slides in the limiting groove 4, the slider 10 slides in the sliding groove 9, providing stability for the sliding of the limiting block 6 and preventing misalignment.

[0027] A handle 14 is fixedly installed on one side of the mounting ring 11. The mounting ring 11 can be pulled flexibly using the handle 14.

[0028] A motor 16 is installed at the top of the tower body 1, and a rotating rod 17 is fixedly installed at the bottom of the motor 16. A first gear 18 is fixedly installed on one side of the rotating rod 17, and a second gear 19 is meshed with the first gear 18. The second gear 19 is fixedly installed on the outer wall of the screw 20, and a threaded block 21 is threadedly connected to the surface of the screw 20. A connecting ring 23 is fixedly connected to one side of the threaded block 21, and a through hole 24 is opened on the inner wall of the connecting ring 23. A feed pipe 25 is fixedly installed on one side of the connecting ring 23. When the motor 16 is operated, the rotating rod 17 is driven to rotate, and the first gear 18 meshes with the second gear 19 to rotate, causing the threaded block 21 to move up and down on the surface of the screw 20. This causes the connecting ring 23 to move up and down. When the additive flows into the feed pipe 25, the liquid in the connecting ring 23 is sprayed into the tower body 1 through the through hole 24. The up and down movement of the spraying can make the spraying more uniform, so that the additive can be more evenly mixed and reacted with the waste gas.

[0029] The inner wall of the tower body 1 has a groove 22, and the threaded block 21 is movably fitted inside the groove 22. When the threaded block 21 moves threadedly on the surface of the screw 20, the threaded block 21 also slides in the groove 22. The groove 22 restricts the threaded block 21 and prevents the threaded block 21 from rotating synchronously with the screw 20.

[0030] Regulating valves are installed on the outer walls of the air inlet pipe 3, air outlet pipe 15, and feed pipe 25. The air inlet, air outlet, and feed of the air inlet pipe 3, air outlet pipe 15, and feed pipe 25 are regulated by the regulating valves.

[0031] Working principle: First, by pushing the handle 14, the mounting ring 11 is slidably into the limiting groove 4. The mounting ring 11 pushes the limiting block 6 to slide into the limiting groove 4, which also causes the telescopic rod 5 to retract and the telescopic spring 8 to extend and retract. When the mounting ring 11 is fully embedded in the limiting groove 4, the telescopic spring 8 pushes the limiting block 6 to move into the slot 13, thereby limiting the installation of the mounting ring 11. The sealing block 7 moves into the slot 13 to seal the upper and lower connection of the mounting ring 11, preventing leakage when filtering dust through the filter screen 12. By operating the pump body 2, the exhaust gas... The gas is discharged into the tower body 1 through the inlet pipe 3. The motor 16 drives the rotating rod 17 to rotate, which in turn drives the first gear 18 to rotate. The first gear 18 meshes with the second gear 19 to rotate, thereby driving the screw 20 to rotate in the groove 22. This causes the threaded block 21 to move up and down on the surface of the screw 20, which in turn drives the connecting ring 23 to move up and down. When the additive flows into the feed pipe 25, the liquid in the connecting ring 23 is sprayed into the tower body 1 through the through hole 24. The up and down movement of the spraying can make the spraying more uniform, so that the additive can be mixed and reacted more evenly with the waste gas.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
