Description

Technical Field

[0001] This invention belongs to the field of waste gas treatment technology, and in particular relates to activated carbon fiber composite materials and oxidation catalysis systems for adsorbing and oxidizing organic waste gases. Background Technology

[0002] Organic waste treatment refers to the physical, chemical, and biological treatment of organic waste and its pollutants to reduce environmental pollution or even turn waste into treasure. Organic waste is an important category of hazardous waste. Some organic wastes are toxic, persistent, and difficult to degrade, thus posing a great threat to the environment and humans. Activated carbon fiber composite materials are often used for adsorption and purification in the treatment of organic waste gas.

[0003] Currently, the surface of activated carbon fiber composite materials is easily damaged by the impact of organic waste gas during operation, which also leads to the loss of catalyst components within the activated carbon fiber composite materials. This results in a slow catalytic oxidation efficiency of organic waste gas by activated carbon fiber composite materials. In addition, the oxidation catalytic system requires frequent maintenance, affecting the reliability and convenience of using the activated carbon fiber composite material oxidation catalytic system.

[0004] Therefore, we propose an activated carbon fiber composite material and an oxidation catalytic system for adsorbing and oxidizing organic waste gas to solve the above problems. Summary of the Invention

[0007] Preferably, the interior of the thin cotton layer is filled with polymetallic oxide catalyst powder.

[0008] Preferably, the wear-resistant layer has a thickness of 0.2-0.5 mm and is made of polyester fiber cloth.

[0009] Preferably, the upper and lower surfaces of the activated carbon fiber layer are provided with multiple contact grooves that are staggered.

[0010] An activated carbon fiber composite material oxidation catalytic system for adsorbing and oxidizing organic waste gas includes the activated carbon fiber composite material for adsorbing and oxidizing organic waste gas as described above, and also includes a purification cylinder and multiple fixed frames for mounting the activated carbon fiber composite material. Two rectangular through holes are opened on both outer walls of the purification cylinder. Two sets of symmetrically distributed movable frames are movably connected to the walls of the rectangular through holes. A first sealing plate is fixedly connected to the outer walls of the two movable frames in each set. A second sealing plate is fixedly connected to the opposite side of the multiple movable frames. A support mesh plate is fixedly connected to the inner wall of the fixed frame. The upper surface of the support mesh plate is movably connected to the lower surface of the adjacent fixed frame. A limit mechanism is fixedly connected to the upper surface of the fixed frame. A driving mechanism is fixedly connected to the outer wall of the purification cylinder.

[0011] Preferably, the limiting mechanism includes multiple cylinders fixedly connected to the upper surface of the fixed frame, a movable ring is movably connected to the inner wall of the cylinder, an insert rod is fixedly sleeved on the inner wall of the movable ring, a spring is movably sleeved on the rod wall of the insert rod, and multiple slots that cooperate with the side ends of the insert rod are provided on the inner wall of the movable frame.

[0012] Preferably, the outer walls of the plurality of insert rods are fixedly connected to a pull plate, and a guide slope is provided on the side of the insert rod near the slot.

[0013] Preferably, the driving mechanism includes a bracket fixedly connected to the outer wall of the purification cylinder, a motor fixedly connected to the inner wall of the bracket, a drive gear fixedly connected to the output end of the motor, two through holes opened on the outer wall of the purification cylinder, and a lead screw connected to the hole wall of the through hole through a sealed bearing, a driven gear fixedly connected to the side end of the lead screw, the outer wall of the driven gear meshing with the outer wall of the drive gear, and the second sealing plate and one of the first sealing plates are provided with threaded holes that cooperate with the lead screw, and the lead screw is located inside the threaded holes.

[0014] Preferably, the outer wall of the purification cylinder is hinged with a cover plate, and the upper surface of the cover plate and the outer wall of the purification cylinder are fixedly connected with a pull rope.

[0015] Preferably, two L-shaped brackets are fixedly connected to the outer wall of the purification cylinder.

[0016] Compared with existing technologies, the advantages of activated carbon fiber composite materials and oxidation catalytic systems for adsorbing and oxidizing organic waste gases are as follows:

[0017] 1. Through the design of the wear-resistant layer, thin cotton layer, and activated carbon fiber layer, when organic waste gas undergoes adsorption and oxidative catalytic purification through the activated carbon fiber composite material, the wear-resistant layer firstly prevents the organic waste gas from impacting and wearing the surface of the activated carbon fiber composite material. Moreover, the multi-metal oxidation catalyst powder in the thin cotton layer can improve the efficiency of organic waste gas oxidation catalysis and increase the conversion rate of organic waste gas treatment. In addition, the thin cotton layer, U-shaped connecting fiber layer, and contact groove can effectively increase the adsorption area of ​​the activated carbon fiber composite material, thereby increasing the adsorption speed. This mechanism can effectively improve the wear resistance and oxidation catalytic conversion rate of the activated carbon fiber composite material, improve the adsorption and purification efficiency, and enhance the reliability and effectiveness of the activated carbon fiber composite material.

[0018] 2. Through the designed drive and limit mechanisms, when the activated carbon fiber composite material in the activated carbon fiber composite oxidation catalytic system requires maintenance after prolonged use, the motor is first started. The motor, through the drive and driven gears, causes the lead screw to rotate rapidly. The lead screw, through the first and second sealing plates, drives the moving frame to move rapidly, causing the moving frame inside the purification cylinder to be quickly discharged, while the moving frame outside the purification cylinder quickly enters the purification cylinder. The newly installed activated carbon fiber composite material in the outer moving frame continues to treat the waste gas. Then, any unqualified activated carbon fiber composite material protruding from the purification cylinder is replaced. This alternating use improves the convenience of maintenance for the oxidation catalytic system, minimizing disruption to its normal operation. Maintenance only requires pulling the limit mechanism to replace the activated carbon fiber composite material inside the moving frame, saving time and effort. This mechanism provides convenient maintenance for the activated carbon fiber composite oxidation catalytic system, minimizing disruption to its normal operation, thereby improving the reliability and convenience of its use.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1, such as Figure 1-4 As shown, the activated carbon fiber composite material for adsorbing and oxidizing organic waste gas includes an activated carbon fiber layer 1. Multiple contact grooves 7 are staggered on the upper and lower surfaces of the activated carbon fiber layer 1, increasing the adsorption area and improving the adsorption effect. An upper fiber cloth layer 2 is connected to the upper surface of the activated carbon fiber layer 1, and a lower fiber cloth layer 3 is connected to the lower surface. U-shaped connecting fiber layers 4 are connected to opposite sides of both the upper and lower fiber cloth layers 2 and 3. A thin cotton layer 5 is connected to the inner wall of the U-shaped connecting fiber layer 4, and the interior of the thin cotton layer 5 is filled with multi-metal oxide catalyst powder. A wear-resistant layer 6, 0.4 mm thick, is sewn onto the upper surface of the U-shaped connecting fiber layer 4 using thread. The wear-resistant layer 6 is made of polyester fiber cloth, which has strong wear resistance. The edges of the upper and lower fiber cloth layers 2 and 3 are connected by thread sewing. This structure effectively improves the wear resistance and oxidation catalytic conversion rate of the activated carbon fiber composite material, and enhances the adsorption and purification efficiency.

[0026] An activated carbon fiber composite material oxidation catalytic system for adsorbing and oxidizing organic waste gas includes the activated carbon fiber composite material for adsorbing and oxidizing organic waste gas as described above, and also includes a purification cylinder 10 and multiple fixed frames 11 for installing the activated carbon fiber composite material. Two rectangular through holes are opened on both outer walls of the purification cylinder 10. Two sets of symmetrically distributed movable frames 12 are movably connected to the walls of the rectangular through holes. A first sealing plate 13 is fixedly connected to the outer walls of the two movable frames 12 in each set. A second sealing plate 14 is fixedly connected to the opposite side of the multiple movable frames 12. A support mesh plate 15 is fixedly connected to the inner wall of the fixed frame 11. The upper surface of the support mesh plate 15 is movably connected to the lower surface of the adjacent fixed frame 11.

[0027] A cover plate 17 is hinged to the outer wall of the purification cylinder 10. A pull rope 18 is fixedly connected to the upper surface of the cover plate 17 and the outer wall of the purification cylinder 10. The cover plate 17 can protect the activated carbon fiber composite material on the outside of the purification cylinder 10. Two L-shaped frames 19 are fixedly connected to the outer wall of the purification cylinder 10. The L-shaped frames 19 can facilitate the installation of the oxidation catalytic system.

[0028] A limiting mechanism 8 is fixedly connected to the upper surface of the fixed frame 11. The limiting mechanism 8 includes multiple cylinders 81 fixedly connected to the upper surface of the fixed frame 11. A movable ring 82 is movably connected to the inner wall of the cylinder 81. A plug rod 83 is fixedly sleeved on the inner wall of the movable ring 82. A pull plate 16 is fixedly connected to the outer wall of the multiple plug rods 83. A guide slope is provided on the side of the plug rod 83 near the slot 85. The pull plate 16 can easily pull the plug rod 83 at the same time. A spring 84 is movably sleeved on the rod wall of the plug rod 83. Multiple slots 85 that cooperate with the side ends of the plug rods 83 are provided on the inner wall of the movable frame 12. This mechanism can easily detach and install the fixed frame 11 from the movable frame 12.

[0029] Example 2 is based on Example 1, such as... Figure 1As shown, a drive mechanism 9 is fixedly connected to the outer wall of the purification cylinder 10. The drive mechanism 9 includes a bracket 91 fixedly connected to the outer wall of the purification cylinder 10. A motor 92 is fixedly connected to the inner wall of the bracket 91. A drive gear 93 is fixedly connected to the output end of the motor 92. Two through holes are opened on the outer wall of the purification cylinder 10, and a lead screw 94 is connected to the hole wall through a sealed bearing. A driven gear 95 is fixedly connected to the side end of the lead screw 94. The outer wall of the driven gear 95 meshes with the outer wall of the drive gear 93. The second sealing plate 14 and one of the first sealing plates 13 are both provided with... The screw 94 is fitted with a threaded hole, and the screw 94 is located inside the threaded hole. This mechanism allows the movable frame 12 outside the purification cylinder 10 to quickly enter the purification cylinder 10 as well, and allows the brand-new activated carbon fiber composite material in the outer movable frame 12 to continue the waste gas treatment work. Then, the unqualified activated carbon fiber composite material protruding from the purification cylinder 10 is replaced. The alternation of the two can improve the convenience of maintenance of the oxidation catalytic system. The maintenance process should not affect the normal operation of the oxidation catalytic system as much as possible, so that the activated carbon fiber composite material oxidation catalytic system has the function of convenient maintenance.

[0030] The operating principle of this invention is described as follows: When organic waste gas is adsorbed and catalytically purified by activated carbon fiber composite material, the wear-resistant layer 6 firstly blocks the impact and wear of organic waste gas on the surface of the activated carbon fiber composite material. Furthermore, the multi-metal oxidation catalyst powder in the thin cotton layer 5 improves the efficiency of organic waste gas oxidation catalysis and increases the conversion rate of organic waste gas treatment. In addition, the thin cotton layer 5, U-shaped connecting fiber layer 4, and contact groove 7 effectively increase the adsorption area of ​​the activated carbon fiber composite material, thereby increasing the adsorption speed. This mechanism effectively improves the wear resistance and oxidation catalytic conversion rate of the activated carbon fiber composite material, enhances the adsorption and purification efficiency, and improves the reliability and effectiveness of the activated carbon fiber composite material. When the activated carbon fiber composite material in the oxidation catalytic system requires maintenance after long-term use, the motor 92 is started first. The motor 92 causes the lead screw 94 to rotate rapidly through the drive gear 93 and driven gear 95. The lead screw 94 passes through the first sealing plate 13 and the second sealing plate... The inlet plate 14 drives the moving frame 12 to move quickly, and the moving frame 12 inside the purification cylinder 10 is quickly discharged. Meanwhile, the moving frame 12 outside the purification cylinder 10 also quickly enters the purification cylinder 10, and the brand-new activated carbon fiber composite material in the outer moving frame 12 continues to treat the waste gas. Then, the unqualified activated carbon fiber composite material protruding from the purification cylinder 10 is replaced. The alternation of the two improves the convenience of maintenance of the oxidation catalytic system. The maintenance process does not affect the normal operation of the oxidation catalytic system as much as possible. Moreover, during maintenance, only the limit mechanism 8 needs to be pulled to replace the activated carbon fiber composite material in the moving frame 12. The insertion rod 83 is pulled by the pull plate 16 to disengage the insertion rod 83 from the slot 85, and the fixed frame 11 and activated carbon fiber composite material are taken out from the moving frame 12 for replacement, which saves time and effort. This mechanism makes the activated carbon fiber composite oxidation catalytic system easy to maintain, and does not affect the normal use of the activated carbon fiber composite oxidation catalytic system as much as possible, thereby improving the reliability and convenience of the activated carbon fiber composite oxidation catalytic system.
