Description

Technical Field

[0001] This application relates to the field of industrial waste gas purification technology, and in particular to an activated carbon adsorption purification device for industrial volatile gases. Background Technology

[0002] Modern industrial production processes, such as chemical, coating, printing, and electronics manufacturing, generate large amounts of waste gases containing volatile organic compounds (VOCs). These gases not only pollute the atmosphere, causing environmental problems like photochemical smog and ozone pollution, but also pose health risks, such as respiratory irritation, cancer, and birth defects. Therefore, the effective purification and treatment of industrial VOCs has become a critical issue that urgently needs to be addressed in the environmental protection field.

[0003] Currently, the main methods for purifying industrial volatile gases include adsorption, combustion, and catalytic oxidation. Among these, activated carbon adsorption is widely used in the treatment of low-concentration, high-volume industrial waste gases due to its advantages such as low cost, simple operation, and high purification efficiency. However, existing activated carbon adsorption equipment for industrial volatile gas purification still has at least the following shortcomings: First, the waste gas is prone to uneven distribution and diffusion within the purification equipment, resulting in insufficient contact between the activated carbon and the waste gas. This means that some activated carbon may not fully exert its adsorption capacity, or some volatile gases in the industrial waste gas may not come into contact with the activated carbon, leading to low purification efficiency and poor purification effect. Second, when the activated carbon inside the equipment becomes saturated, it needs to be shut down and replaced, affecting the continuity of industrial production and waste gas purification treatment, thus limiting its practicality.

[0004] Therefore, we propose an activated carbon adsorption purification device for industrial volatile gases to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide an activated carbon adsorption industrial volatile gas purification device, which can replace the activated carbon particles in the volatile gas purification treatment box without stopping the machine, thereby improving efficiency and ensuring the continuity of industrial production and waste gas purification treatment.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: an activated carbon adsorption industrial volatile gas purification device, comprising an industrial volatile gas purification cabinet, wherein a partition is fixedly installed inside the industrial volatile gas purification cabinet, and a waste gas inlet pipe located below the partition is fixedly connected to the left side of the industrial volatile gas purification cabinet. Two volatile gas purification treatment boxes located above the partition are fixedly installed inside the industrial volatile gas purification cabinet, and the sides of the two volatile gas purification treatment boxes that are far apart from each other extend outside the industrial volatile gas purification cabinet. The bottom inner walls of both volatile gas purification treatment boxes are... Hollow gas collecting plates are fixedly installed. The bottom of each hollow gas collecting plate is fixedly connected to a waste gas conveying pipe. One end of each waste gas conveying pipe extends into the industrial volatile gas purification cabinet and is located below the partition. Multiple evenly distributed gas distribution pipes are installed on the top of each hollow gas collecting plate. Activated carbon particles are placed in each of the two volatile gas purification treatment boxes above the hollow gas collecting plates. Exhaust branch pipes are fixedly connected to the top of each of the two volatile gas purification treatment boxes. The top of the industrial volatile gas purification cabinet is fixedly connected to a main exhaust pipe. The ends of the two exhaust branch pipes that are close to each other are fixedly connected to the main exhaust pipe.

[0007] A further feature of this application is that: a solenoid valve 1 is fixedly installed on each of the two exhaust gas delivery pipes, and a solenoid valve 2 is fixedly installed on each of the two exhaust branch pipes.

[0008] A further feature of this application is that a dust filter is fixedly installed inside the industrial volatile gas purification cabinet, and the dust filter is located between the exhaust gas conveying pipe and the exhaust gas inlet pipe.

[0009] A further feature of this application is that the dust filter is an arc-shaped structure with a concave center.

[0010] A further feature of this application is that baffle screens are fixedly installed on the top inner walls of both volatile gas purification and treatment boxes, and the ends of the two exhaust branch pipes away from the exhaust main pipe are respectively located inside the corresponding baffle screens.

[0011] A further feature of this application is that the air distribution pipe includes a Y-shaped pipe and multiple spherical air outlets. The Y-shaped pipe is fixedly connected to the top of the hollow air collection plate, and the multiple spherical air outlets are all fixedly installed on the Y-shaped pipe and are evenly distributed.

[0012] A further feature of this application is that each of the two volatile gas purification treatment boxes has a cleaning port located in the industrial volatile gas purification cabinet on its top, and each of the two volatile gas purification treatment boxes has a sealing cover plate fixed to its top by screws, with the two sealing covers plate being adapted to the corresponding cleaning port.

[0013] A further feature of this application is that a second cleaning port located below the dust filter is provided on the front side wall of the industrial volatile gas purification cabinet, and a second sealing cover is fixedly installed on the front side wall of the industrial volatile gas purification cabinet by screws, the second sealing cover being adapted to the second cleaning port.

[0014] This application includes at least one of the following beneficial technical effects:

[0015] 1. With the coordinated action of two volatile gas purification treatment boxes, two waste gas conveying pipes, two exhaust branch pipes, two solenoid valves and two solenoid valves, the direction of industrial waste gas flow can be flexibly adjusted. The two volatile gas purification treatment boxes can be used alternately to carry out comprehensive and efficient adsorption purification treatment of volatile gases in industrial waste gas. The activated carbon particles in the volatile gas purification treatment boxes can be replaced without stopping the machine, thereby improving efficiency and ensuring the continuity of industrial production and waste gas purification treatment.

[0016] 2. This application, by setting multiple evenly distributed gas distribution pipes on the hollow gas collection plate, and using a combination of Y-shaped pipes and spherical gas outlets, allows for a more uniform and widespread distribution of waste gas within the volatile gas purification treatment box compared to traditional straight pipe gas distribution methods. This enables the industrial waste gas to diffuse evenly and comprehensively, flowing upwards through the activated carbon particles, ensuring a full contact area between the volatile gases in the industrial waste gas and the activated carbon particles. This fully utilizes the adsorption capacity of the activated carbon particles, resulting in a more comprehensive and effective removal of volatile gases from the industrial waste gas, improving purification efficiency and quality, and enhancing the comprehensiveness and effectiveness of activated carbon particles in adsorbing and purifying volatile gases in industrial waste gas.

This intercepts and blocks dust particles in the waste gas in the space below the dust filter, effectively preventing dust particles from entering the volatile gas purification treatment cabinet.

[0024] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] See Figures 1-5This application provides an activated carbon adsorption purification device for industrial volatile gases, including an industrial volatile gas purification cabinet 1. A partition 2 is fixedly installed inside the industrial volatile gas purification cabinet 1. A waste gas inlet pipe 3 located below the partition 2 is fixedly connected to the left side of the industrial volatile gas purification cabinet 1. Two volatile gas purification treatment boxes 4 are fixedly installed inside the industrial volatile gas purification cabinet 1, located above the partition 2. The sides of the two volatile gas purification treatment boxes 4 that are furthest from each other extend outside the industrial volatile gas purification cabinet 1. Hollow gas collecting plates 5 are fixedly installed on the bottom inner wall of the volatile gas purification treatment box 4. Waste gas conveying pipes 6 are fixedly connected to the bottom of both hollow gas collecting plates 5. One end of each waste gas conveying pipe 6 extends into the industrial volatile gas purification cabinet 1 and is located below the partition plate 2. Multiple evenly distributed gas distribution pipes 8 are installed on the top of both hollow gas collecting plates 5. Activated carbon particles 9 are placed above the hollow gas collecting plates 5 inside both volatile gas purification treatment boxes 4. Under the synergistic effect of 8, the waste gas entering the volatile gas purification treatment box 4 can be evenly and comprehensively diffused and flow from bottom to top through the activated carbon particles 9, ensuring that the contact area between the volatile gases in the waste gas and the activated carbon particles 9 is comprehensive, giving full play to the adsorption capacity of the activated carbon particles 9, and more comprehensively and effectively removing the volatile gases in the industrial waste gas, improving purification efficiency and quality. The top of each of the two volatile gas purification treatment boxes 4 is fixedly connected to an exhaust branch pipe 10, and the top of the industrial volatile gas purification cabinet 1 is fixedly connected to an exhaust main pipe 11. The two exhaust branch pipes 10 are fixedly connected to the exhaust main pipe 11 at their closest ends. By setting two volatile gas purification treatment boxes 4, two waste gas conveying pipes 6 and two exhaust branch pipes 10 on the industrial volatile gas purification cabinet 1, they can be used alternately to adsorb and purify the volatile gases in the industrial waste gas. In this way, the activated carbon particles 9 in the volatile gas purification treatment box 4 can be replaced without stopping the machine, improving purification efficiency and ensuring continuous and stable waste gas purification treatment and industrial production.

[0026] In this embodiment, the gas distribution pipe 8 includes a Y-shaped pipe 81 and multiple spherical gas outlets 82. The Y-shaped pipe 81 is fixedly connected to the top of the hollow gas collection plate 5, and the multiple spherical gas outlets 82 are all fixedly installed on the Y-shaped pipe 81 and are evenly distributed. The gas distribution pipe 8 adopts a combination of Y-shaped pipe 81 and spherical gas outlets 82. Compared with the traditional straight pipe gas distribution method, it can make the waste gas more evenly and widely distributed in the volatile gas purification treatment box 4, and improve the comprehensiveness and effectiveness of activated carbon particles 9 in adsorbing and purifying volatile gases in industrial waste gas.

[0027] In this embodiment, solenoid valve 7 is fixedly installed on both exhaust gas conveying pipes 6, and solenoid valve 12 is fixedly installed on both exhaust branch pipes 10. The design of the two solenoid valves 7 and 12 allows for flexible adjustment of the industrial exhaust gas flow direction. When the activated carbon particles 9 in one of the volatile gas purification treatment boxes 4 need to be replaced, the corresponding solenoid valve 7 and 12 are closed, and the other solenoid valve 7 and 12 are opened. This allows the other volatile gas purification treatment box 4 to continue its exhaust gas purification work, enabling equipment maintenance without shutdown and ensuring the continuity of industrial production and exhaust gas purification treatment.

[0028] In this embodiment, a dust filter 13 is fixedly installed inside the industrial volatile gas purification cabinet 1. The dust filter 13 is located between the exhaust gas conveying pipe 6 and the exhaust gas inlet pipe 3. The dust filter 13 is designed to perform dust removal and filtration treatment on the exhaust gas entering the industrial volatile gas purification cabinet 1. It can intercept and block dust particles in the exhaust gas in the space below the dust filter 13, effectively preventing dust particles from entering the volatile gas purification treatment box 4. The dust filter 13 has an arc shape with a concave center, which can increase the filtration area for dust particles and make the filter holes on the dust filter 13 less likely to be completely blocked, maintaining the good air permeability of the dust filter 13, ensuring effective interception and filtration of dust particles in the exhaust gas, and reducing the frequency of cleaning the dust filter 13.

[0029] In this embodiment, baffles 14 are fixedly installed on the top inner walls of the two volatile gas purification treatment boxes 4. The ends of the two exhaust branch pipes 10 away from the exhaust main pipe 11 are respectively located in the corresponding baffles 14. The aperture size of the baffles 14 is smaller than the particle size of the activated carbon particles 9. The baffles 14 can block and intercept the activated carbon particles 9, preventing them from entering the exhaust branch pipes 10.

[0030] In this embodiment, the top of each of the two volatile gas purification treatment boxes 4 is provided with a cleaning port 15 located in the industrial volatile gas purification cabinet 1. The top of each of the two volatile gas purification treatment boxes 4 is fixed with a sealing cover 16 by screws. The two sealing covers 16 are respectively adapted to the corresponding cleaning ports 15. The design of the cleaning ports 15 and the sealing covers 16 is to replace the activated carbon particles 9 in the volatile gas purification treatment box 4.

[0031] In this embodiment, a second cleaning port located below the dust filter 13 is provided on the front side wall of the industrial volatile gas purification cabinet 1. A second sealing cover 17 is fixedly installed on the front side wall of the industrial volatile gas purification cabinet 1 by screws. The second sealing cover 17 is adapted to the second cleaning port. The design of the second cleaning port and the second sealing cover 17 facilitates the cleaning out of the dust particles located below the dust filter 13 inside the industrial volatile gas purification cabinet 1.

[0032] In this embodiment, it should be noted that both solenoid valve 7 and solenoid valve 12 are commercially available, and their wiring connection and control methods are mature technologies in the field and have been fully disclosed, so they will not be described in detail here.

[0033] With the above structure, when the activated carbon adsorption industrial volatile gas purification equipment provided in this application is in use, the industrial waste gas enters the industrial volatile gas purification cabinet 1 through the waste gas inlet pipe 3 and is located in the space below the partition 2. At this time, the dust filter 13 first starts to play its role. With its arc-shaped structure increasing the filtration area, delaying filter pore clogging, and maintaining good air permeability, it comprehensively and effectively intercepts and filters the dust particles in the waste gas, so that the dust particles are blocked in the space below the dust filter 13. After dust removal and filtration, the industrial waste gas continues to rise through the filter pores on the dust filter 13. At this time, the left solenoid valve 7 and the right solenoid valve 12 are opened, while the right solenoid valve 7 and the right solenoid valve 12 are kept closed. The dust-filtered industrial waste gas will pass through the left side. The waste gas is conveyed through the exhaust pipe 6 into the hollow gas collection plate 5 inside the volatile gas purification treatment box 4 on the left (during this period, the volatile gas purification treatment box 4 on the right is in standby mode). The industrial waste gas entering the hollow gas collection plate 5 is then discharged through multiple spherical gas outlets 82, which allows the industrial waste gas to be evenly dispersed and diffused into the activated carbon particles 9 in a comprehensive and uniform manner. The waste gas passes through the activated carbon particles 9 from bottom to top. With its rich microporous structure and huge specific surface area, the activated carbon particles 9 capture the volatile gas molecules in the industrial waste gas through physical adsorption and van der Waals forces, thereby achieving efficient and comprehensive purification treatment of the volatile gases in the industrial waste gas. The purified gas continues to rise and is discharged through the exhaust branch pipe 10 on the left and finally merges into the exhaust main pipe 11.

[0034] When the activated carbon particles 9 in the volatile gas purification chamber 4 on the left are nearing saturation and need to be replaced, open the solenoid valves 7 and 12 on the right, and then close the solenoid valves 7 and 12 on the left. At this time, the industrial waste gas, after dust removal and filtration, will enter the hollow gas collecting plate 5 in the volatile gas purification chamber 4 on the right through the waste gas conveying pipe 6 on the right. According to the above waste gas treatment principle, the activated carbon particles 9 in the volatile gas purification chamber 4 on the right can continue to efficiently and comprehensively purify the volatile gases in the industrial waste gas. During this period, the operator can use a wrench. Remove the sealing cover 16 on the top of the left volatile gas purification chamber 4, clean out the activated carbon particles 9 inside, refill with new activated carbon particles 9, and finally replace the sealing cover 16 in its original position. The left volatile gas purification chamber 4 can then be used as a standby unit. By using the two volatile gas purification chambers 4 alternately, comprehensive and efficient adsorption and purification of volatile gases in industrial waste gas can be achieved. The activated carbon particles 9 inside the volatile gas purification chamber 4 can be replaced without stopping the machine, improving efficiency and ensuring the continuity of industrial production and waste gas purification.
