Description

A purification device for petrochemical waste gas Technical Field

[0001] This utility model relates to the field of waste gas treatment equipment, and in particular to a purification device for petrochemical waste gas. Background Technology

[0002] In the production process of the petrochemical industry, a large amount of complex and harmful waste gas is generated. This waste gas includes inorganic waste gas such as ammonia, hydrogen sulfide, and sulfur dioxide, as well as organic waste gas such as benzene, toluene, and xylene. Its strong odor not only pollutes the surrounding environment, but also causes great harm to human health. Therefore, the development of efficient and reliable petrochemical waste gas purification devices has become a key issue that urgently needs to be solved in the field of environmental protection.

[0003] In existing technologies, various processes and equipment are employed for the purification of petrochemical waste gas. For example, some equipment utilizes the adsorption properties of activated carbon, using its porous structure to adsorb organic molecules in the waste gas, achieving preliminary purification; others use combustion methods, decomposing the waste gas into harmless substances at high temperatures. When treating organic waste gas, some UV photolysis purification equipment uses specially designed high-energy UV ultraviolet light beams to irradiate the waste gas, breaking down the molecular chains of organic compounds and degrading them into low-molecular-weight compounds. Its working principle is that the waste gas is conveyed into the equipment by a fan, first passing through a filter to remove large molecules and particles, and then undergoing a decomposition reaction under ultraviolet irradiation in the reaction chamber.

[0004] However, a significant problem exists in traditional equipment for purifying waste gas using ultraviolet irradiation: the ultraviolet lamps in these devices are positioned relatively fixed. When irradiating and purifying waste gas, the fixed irradiation angle and range can easily create irradiation dead zones inside the equipment. Some waste gas cannot be fully irradiated by ultraviolet light, making it difficult to achieve effective pyrolysis and purification. This reduces the overall purification effect of the equipment on chemical waste gas and affects the quality of waste gas emissions meeting standards. Therefore, a purification device for petrochemical waste gas is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a purification device for petrochemical waste gas, which aims to improve the problem that the position of the ultraviolet lamp in traditional equipment is relatively fixed, which easily leads to blind spots in irradiation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A purification device for petrochemical waste gas includes a purification box, a fixing block 1 is fixedly connected to the inner wall of the purification box, a plurality of ultraviolet lamps are arranged on the inner wall of the fixing block 1, and a rotating component and a purification component are arranged on the outer wall of the plurality of ultraviolet lamps.

[0008] The rotating assembly includes a gear ring and a gear, which are located on one side of the plurality of ultraviolet lamps. A connecting tube is fixedly connected to the outer side of the plurality of ultraviolet lamps. A plurality of limiting rings are fixedly connected to the outer wall of the connecting tube. The plurality of limiting rings are rotatably connected inside the first fixing block. One side of the connecting tube is fixedly connected to one end of the gear ring.

The bottom of the support plate is fixedly connected to the bottom of the inner wall of the purification box.

[0013] As a further description of the above technical solution:

[0014] The purification component includes a manganese-based ozone decomposition catalyst plate, which is located on the outer wall of the plurality of ultraviolet lamps. A frame is fixedly connected to the outer wall of the manganese-based ozone decomposition catalyst plate, and the frame is attached to the connecting pipe.

[0015] As a further description of the above technical solution:

[0016] Multiple connecting shells arranged in a circular array are fixedly connected inside the frame. Each connecting shell has a fixing shell on its outer wall, and the outer walls of the multiple fixing shells are fixedly connected inside the connecting tube.

[0019] As a further description of the above technical solution:

[0020] Each of the threaded rods is fixedly connected to a connecting post at the other end, and a frustum push block is fixedly connected to one end of each connecting post.

[0021] As a further description of the above technical solution:

[0022] The connecting shell has multiple holes inside, and each hole has a ball slidably connected to its inner wall. The diameter of the inner wall of each hole is larger on the inward side than on the outward side, and the diameter on the outward side is smaller than the outer diameter of the ball. The ball engages with the inside of the fixed shell, and the frustum pusher is in contact with the ball.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Referring to Figures 1-4, one embodiment of this utility model is provided: a purification device for petrochemical waste gas, including a purification box 1, a fixing block 2 fixedly connected to the inner wall of the purification box 1, a plurality of ultraviolet lamps 6 arranged on the inner wall of the fixing block 2, the fixing block 2 is used to support the ultraviolet lamps 6 and provide them with a stable installation position to ensure that the ultraviolet lamps 6 remain stable during operation, and a rotating component and a purification component are arranged on the outer wall of the plurality of ultraviolet lamps 6.

[0036] The rotating assembly includes a gear ring 5 and a gear 8, located on one side of multiple ultraviolet lamps 6. The gear ring 5 and gear 8 mesh with each other to achieve transmission, driving the connecting pipe 3 to rotate, allowing the ultraviolet lamps 6 to evenly irradiate the chemical waste gas. The connecting pipe 3 is fixedly connected to one side of the multiple ultraviolet lamps 6, fixing the ultraviolet lamps 6 and transmitting rotational power, enabling the ultraviolet lamps 6 to revolve. Multiple limiting rings 4 are fixedly connected to the outer wall of the connecting pipe 3, limiting the axial displacement of the connecting pipe 3 and preventing it from shifting during rotation. The multiple limiting rings 4 are rotatably connected inside the fixing block 1 2. One side of the connecting pipe 3 is fixedly connected to one end of the gear ring 5. Multiple reflectors 7 are fixedly connected to the inner wall of the connecting pipe 3, reflecting the ultraviolet light, enhancing the ultraviolet irradiation range, and improving the purification efficiency of the chemical waste gas. A fixing block 2 12 is fixedly connected to the outer wall of the purification box 1, fixing the motor 11 and ensuring the smooth operation of the motor 11. For stability, a drive assembly is provided at one end of gear 8. The drive assembly includes a motor 11, which is located at one end of gear 8. Motor 11 provides power to drive gear 8 to rotate, thereby driving gear ring 5 and connecting pipe 3 to rotate. A fixing block 2 12 is fixedly connected to the outer wall of purification box 1. One side of fixing block 2 12 is fixedly connected to the outer wall of motor 11. The output end of motor 11 extends through into the interior of purification box 1 and is fixedly connected to transmission column 10. Transmission column 10 is used to transmit the power of motor 11 to gear 8 to realize power transmission. One end of transmission column 10 is fixedly connected to the outer wall of gear 8. Gear 8 and gear ring 5 mesh with each other. The meshing transmission of gear 8 and gear ring 5 realizes the rotational movement of connecting pipe 3, so that ultraviolet lamp 6 can fully irradiate chemical waste gas. A support plate 9 is rotatably connected to the outer wall of transmission column 10. Support plate 9 is used to support transmission column 10 and reduce vibration and friction during transmission. The bottom of support plate 9 is fixedly connected to the bottom of inner wall of purification box 1.

[0037] Referring to Figures 3, 5, and 6, the purification assembly includes a manganese-based ozone decomposition catalyst plate 13. The manganese-based ozone decomposition catalyst plate 13 is located on the outer wall of multiple ultraviolet lamps 6. The manganese-based ozone decomposition catalyst plate 13 is used to decompose the ozone generated by the ultraviolet lamps 6, preventing secondary pollution. A frame 14 is fixedly connected to the outer wall of the manganese-based ozone decomposition catalyst plate 13. The frame 14 is used to fix the manganese-based ozone decomposition catalyst plate 13 and facilitates disassembly and replacement. The frame 14 is fitted to the connecting pipe 3, and a ring array is fixedly connected inside the frame 14. Multiple connecting shells 18 are arranged in a row. The connecting shells 18 are used to install threaded rods 17 and retaining balls 21, enabling quick fixing and disassembly of the frame 14. Each connecting shell 18 has a fixing shell 22 on its outer wall, which cooperates with the retaining ball 21 to fix the position of the frame 14. The outer walls of the multiple fixing shells 22 are fixedly connected to the inside of the connecting tube 3. Each connecting shell 18 has a threaded rod 17 threadedly connected to its inner wall. The threaded rod 17 is used to push the frustum pusher 20 to move, controlling the engagement and disengagement of the retaining ball 21. Each threaded rod 17... Each of the 7 parts is fixedly connected to a transmission column 16 at one end. The transmission column 16 is used to transmit rotational force to the threaded rod 17 for easy operation. Each transmission column 16 is fixedly connected to a handle 15 at one end. The handle 15 is used to facilitate the operator to rotate the threaded rod 17 to disassemble and install the frame 14. Multiple handles 15 are located on the outside of the frame 14. Each threaded rod 17 is fixedly connected to a connecting column 19 at the other end. The connecting column 19 is used to connect the threaded rod 17 to the frustum push block 20 to transmit thrust. Each connecting column 19 is fixedly connected to a connecting column 19 at one end. A frustum pusher 20 is fixedly connected to the fixed shell 22. The frustum pusher 20 is used to push the locking ball 21 to move, so as to achieve engagement and disengagement. Multiple holes are opened inside the connecting shell 18. The locking ball 21 is slidably connected to the inner wall of each hole. The locking ball 21 is used to engage with the groove inside the fixed shell 22 to fix the position of the frame 14. The diameter of the inner wall of each hole is larger on the inward side than on the outward side, and the diameter on the outward side is smaller than the outer diameter of the locking ball 21. The locking ball 21 engages with the inside of the fixed shell 22, and the frustum pusher 20 is in contact with the locking ball 21.

[0038] Working principle: During equipment use, the ultraviolet lamp 6 is activated, utilizing the light generated by the ultraviolet lamp 6 to purify the chemical waste gas. The reflector 7 reflects the light, allowing more ultraviolet light to irradiate the surface of the chemical waste gas. Then, the motor 11 is activated, and the output end of the motor 11 drives the gear 8 at one end of the transmission column 10 to rotate on the inner wall of the gear ring 5. Since the gear ring 5 and the gear 8 mesh, they drive the connecting pipe 3 at one end of the gear ring 5 to rotate, causing multiple ultraviolet lamps 6 on the inner wall of the connecting pipe 3 to revolve. This ensures that the chemical waste gas is fully irradiated by the ultraviolet light. The limiting ring 4 limits the position of the connecting pipe 3 to prevent it from shifting during rotation. Ultimately, this achieves a good purification effect on the chemical waste gas, solving the problem of the relatively fixed position of the ultraviolet lamp 6 in traditional equipment, which easily leads to blind spots in irradiation. This enhances the purification effect of the equipment on chemical waste gas.

[0039] The ultraviolet light emitted by the ultraviolet lamp 6 easily reacts with oxygen to generate excess ozone. When this ozone passes through the pores and gaps inside the manganese-based ozone decomposition catalyst plate 13, the manganese-based ozone decomposition catalyst plate 13 decomposes the ozone into oxygen. For example, MnO2 / γ-Al2O3 is a common manganese-based ozone decomposition catalyst. MnO2 is the active component that plays a catalytic role, and γ-Al2O3, as a carrier, can increase the specific surface area of ​​the catalyst, allowing MnO2 to be better dispersed and improving catalytic efficiency. By using a synergistic approach of photocatalysis and thermocatalysis, ozone is decomposed into oxygen. Photocatalysis uses ultraviolet light to irradiate a catalyst, exciting its electronic transitions and generating highly oxidizing active species to accelerate ozone decomposition. Thermal catalysis utilizes the heat generated during the reaction to allow ozone to undergo a chemical reaction on the catalyst surface, decomposing it into oxygen, thus achieving ozone removal and preventing secondary pollution. This is existing technology and will not be elaborated further. When the manganese-based ozone decomposition catalyst inside the manganese-based ozone decomposition catalyst plate 13 needs replacement, rotating the handle 15 causes the threaded rod 17 at one end of the transmission column 16 to rotate within the inner wall of the connecting shell 18. Since the threaded rod 17 is threadedly connected to the connecting shell 18, its rotation drives the frustum pusher 20 towards the handle 15 via the connecting column 19, until the frustum pusher 20 separates from the outer wall of the retaining ball 21. Because the connecting shell 18... The internal opening has a structure that is larger at one end and smaller at the other. This provides sliding space for the ball 21 while preventing it from accidentally falling out of the fixed shell 22. Next, the frame 14 is pulled, and the groove inside the fixed shell 22 pushes the ball 21 to move towards the inside of the connecting shell 18. Once the ball 21 is completely separated from the inner wall of the fixed shell 22, the frame 14 can be easily separated from the outer wall of the connecting tube 3. Then, the frame 14 on the outer wall of the other manganese-based ozone decomposition catalyst plate 13 is moved back to one end of the connecting tube 3. Based on the same principle, the ball 21 engages with the groove inside the fixed shell 22, thus fixing the position of the frame 14. This achieves the ozone purification effect of the equipment and solves the problem that the ultraviolet light generated by the ultraviolet lamp 6 in traditional equipment easily reacts with oxygen to form excessive ozone, thereby enhancing the ozone purification effect of the equipment.
