Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of activated carbon gas emission treatment equipment, specifically an activated carbon gas emission treatment device. Background Technology
[0002] Activated carbon gas emission treatment devices are equipment that utilize the adsorption properties of activated carbon to treat harmful gases. Their core function is to purify pollutant-containing gases generated in industrial or domestic environments. Their working principle is based on the porous structure of activated carbon. When gases containing formaldehyde, benzene, VOCs, or odors flow through the device, pollutant molecules are adsorbed onto the surface of the activated carbon, thus ensuring that the emitted gas meets environmental emission standards. This device is widely used in industries such as chemical, printing, and coating, as well as in indoor air purification scenarios. It features simple operation, low cost, and direct purification effects, but requires regular replacement of the activated carbon to maintain treatment efficiency.
[0003] For example, a VOC gas activated carbon adsorption, treatment and emission device disclosed in Chinese patent literature (announcement number: CN215610385U) utilizes multiple activated carbon layers in the first, second, third and fourth carbon boxes to allow the gas to be adsorbed layer by layer, thereby increasing the carbon adsorption time, extending the adsorption gas channel, and making the waste gas treatment more thorough. The front and rear carbon boxes facilitate the replacement of activated carbon layers, simplify the operation process and meet the needs of environmental protection improvement.
[0004] However, when replacing the carbon, the doors on the front and back sides of the carbon box must be opened first, and then the internal activated carbon layers must be removed one by one through the movable snap-fit structure. After the new activated carbon layers are replaced, they must be reinstalled one by one. The whole process is complicated, which not only consumes a lot of manpower and time, but also easily leads to low efficiency due to the repetitive nature of the layer-by-layer operation.

[0023] Reference Figures 1 to 5 In this embodiment of the present invention, an activated carbon gas emission treatment device includes: carbon canister 1, carbon canister 2, and exhaust manifold 3. Carbon canister 1 and carbon canister 2 both serve as containers for the treated gas, and exhaust manifold 3 serves as a collection point for the compliant gas treated by the two sets of carbon canisters, achieving unified emission and simplifying the exhaust path.
[0024] An exhaust branch pipe 4 is fixedly connected to the upper outer side of the carbon canister 1. One end of the exhaust branch pipe 4 is fixedly connected to a vacuum pump 5. The exhaust branch pipe 4 serves as a connection between the upper end of a single carbon canister and the vacuum pump 5, transporting the adsorbed gas in the carbon canister to the vacuum pump 5. It is an intermediate channel for gas discharge. The vacuum pump 5 pumps the qualified gas in the carbon canister to the exhaust main pipe 3. Before replacing the activated carbon, it can also remove the residual gas in the carbon canister to prevent leakage.
[0025] The carbon canister 1 is equipped with a processing mechanism 6 inside, which is a core adsorption mechanism that can be quickly replaced. The bottom of the carbon canister 1 is fixedly connected to an air inlet pipe 7, which introduces the gas to be treated into the carbon canister and is the inlet for the gas to enter the adsorption system. One end of the air inlet pipe 7 is fixedly connected to a gas valve 8, which controls the opening and closing of the air inlet pipe 7. One end of the gas valve 8 is fixedly connected to a gas delivery pipe 9, which delivers the external gas to be treated to the device.
[0026] The outlet of the vacuum pump 5 is fixedly connected to the exhaust main pipe 3. There are two sets of exhaust branch pipes 4, vacuum pump 5, processing mechanism 6, inlet pipe 7, air valve 8 and gas delivery pipe 9. The other set of exhaust branch pipes 4 is located on the upper outer side of carbon canister 2, the other set of processing mechanism 6 is located inside carbon canister 2, and the other set of inlet pipe 7 is located at the bottom of carbon canister 2. Two independent processing units, carbon canister 1 and carbon canister 2, are set up. The gas can be controlled to enter one set of carbon canisters by switching the air valve 8. The other set can be used as a backup or maintenance unit, which can ensure that the entire VOC treatment process is uninterrupted. It is especially suitable for industrial scenarios with high requirements for continuous treatment.
[0027] Reference Figure 1 and Figure 2 Multiple sets of support legs 10 are symmetrically fixed to the outside of carbon canister 1, and multiple sets of support legs 10 are also symmetrically arranged on the outside of carbon canister 2. These support legs 1 and 2 are kept stable and prevent them from being directly exposed to the ground and getting damp or damaged. A base 11 is fixedly connected to the bottom of the support legs 10 to fix the entire device to the ground and improve the overall stability of the equipment.
[0028] Reference Figures 1 to 5 The processing mechanism 6 includes a first fixed coupling ring 61, a second fixed coupling ring 62, and a third fixed coupling ring 63. The first fixed coupling ring 61 is fixedly connected to the upper end of the inner wall of the carbon canister 1, the second fixed coupling ring 62 is fixedly connected to the middle end of the inner wall of the carbon canister 1, and the third fixed coupling ring 63 is fixedly connected to the lower end of the inner wall of the carbon canister 1.
[0029] The external threaded can lid 64, handle 65, and top sealing ring 66 are provided. The external threaded can lid 64 is threaded to the top of the carbon can 1. The handle 65 is fixedly connected to the upper middle part of the external threaded can lid 64. The top sealing ring 66 is fixedly connected to one bottom end of the external threaded can lid 64.
[0030] Connector 67 and placement component 68 are provided. Connector 67 is fixedly connected to the other end of the bottom of the external thread can cover 64, and placement component 68 is disposed at the bottom of connector 67.
[0031] The dimensions of the fixed mating ring 61, fixed mating ring 62, and fixed mating ring 63 decrease sequentially. The top sealing ring 66 is movably inserted into the top sealing groove of the carbon canister 1. By holding the handle 65 and rotating the external threaded canister cover 64, it can be removed from the top of the carbon canister 1. Then, the external threaded canister cover 64, the connector 67, and the placement assembly 68 connected to the connector 67 can be removed from the carbon canister 1. During installation, the top sealing ring 66 is connected to the bottom of the carbon canister 1 to achieve a sealing effect.
[0032] Reference Figures 3 to 5 The placement component 68 includes: a circular box 681, an inner sealing ring 682, and a connector 683. The circular box 681 is fixedly connected to the bottom of the connector 67. The inner sealing ring 682 is fixedly connected to the lower outer side of the circular box 681. The inner sealing ring 682 is movably inserted into the fixed mating ring 61. The connector 683 is fixedly connected to the bottom of the circular box 681.
[0033] The circular box 684, the inner sealing ring 685, and the connector 686 are fixedly connected to the bottom of the connector 683. The inner sealing ring 685 is fixedly connected to the lower outer side of the circular box 684. The inner sealing ring 685 is movably inserted into the fixed mating ring 62. The connector 686 is fixedly connected to the bottom of the circular box 684.
[0034] The circular box 3 687 and the inner sealing ring 3 688 are fixedly connected to the bottom of the connector 3 686, and the inner sealing ring 3 688 is fixedly connected to the lower outer side of the circular box 3 687. The inner sealing ring 3 688 is movably inserted into the fixed mating ring 3 63.
[0035] Both carbon canister 1 and carbon canister 2 have a stepped structure, with the outer diameter decreasing in a stepped manner from top to bottom. The bottoms of circular boxes 1 (681), 2 (684), and 3 (687) are all filter structures, with the dimensions of circular boxes 1 (681), 2 (684), and 3 (687) decreasing sequentially. Gas entering carbon canister 1 flows upward from the bottom and, through the stepped multi-layer adsorption structure, passes sequentially through circular boxes 3 (687), 2 (684), and 1 (681). The gas passes through the bottom of each layer of circular boxes. When the filter structure is in place, it will fully contact the activated carbon. Compared with single-layer adsorption, it prolongs the contact time between the gas and the activated carbon, and can more fully adsorb VOC components, reducing the risk of direct emission of untreated gas. During installation, the three circular boxes are tightly connected to the inner sealing rings 682 and 685 on the outside and 688 on the inner wall of the carbon canister 1, respectively, with the fixed mating rings 61, 62 and 63, to prevent gas from flowing around and ensure that all gas passes through the activated carbon for adsorption.
[0036] The working principle of this utility model is as follows: When in use, the gas to be treated is transported to the device through the gas supply pipe 9. The corresponding carbon canister is opened, such as the gas valve 8 on the bottom air inlet pipe 7 of carbon canister 1. The gas enters the interior of carbon canister 1 along the air inlet pipe 7. The gas entering carbon canister 1 flows upward from the bottom. Through the adoption of a stepped multi-layer adsorption structure, it passes through the circular box 3 687, the circular box 2 684 and the circular box 1 681 in sequence. When the gas passes through the filter structure at the bottom of each circular box, it will have full contact with the activated carbon. Compared with single-layer adsorption, the contact time between the gas and the activated carbon is extended, which can more fully adsorb VOC components and reduce the risk of direct emission of untreated gas. The VOC components are adsorbed layer by layer and expanded. After multi-layer adsorption, the qualified gas enters the suction pump 5 through the exhaust branch pipe 4 at the top of carbon canister 1. The suction pump 5 provides power to transport the gas to the exhaust main pipe 3, and finally discharges it through the exhaust main pipe 3.
[0037] When the activated carbon is saturated and needs to be replaced, close the gas valve 8 of carbon canister 1, and use the vacuum pump 5 to remove the gas from carbon canister 1. Then, hold the handle 65 and rotate the external threaded canister cap 64 to remove it from the top of carbon canister 1. The bottom of the external threaded canister cap 64 is connected to the integrated structure consisting of circular box 1 681, circular box 2 684, and circular box 3 687 via connector 1 67. By removing the external threaded canister cap 64, the three sets of circular boxes can be taken out together. Replace the new integrated processing mechanism 6 filled with activated carbon. When inserting, since all three circular boxes are filled with activated carbon and their size decreases from top to bottom, they match the stepped canister body of carbon canister 1. The outer and inner sides of the three circular boxes are also aligned. The sealing ring 682, the inner sealing ring 685, and the inner sealing ring 688 are respectively tightly inserted into the fixed engagement ring 61, the fixed engagement ring 62, and the fixed engagement ring 63 on the inner wall of the carbon canister 1 to prevent gas from flowing around and ensure that all gas is adsorbed by the activated carbon. Then, tighten the rotating outer thread canister cap 64. In this way, the activated carbon can be replaced quickly without disassembling the internal structure of the carbon canister 1 layer by layer. The operation steps are simple, which can greatly shorten the replacement time and greatly improve the efficiency of the replacement operation. At the same time, it can prevent the gas from leaking out of the carbon canister 1 when replacing activated carbon, and also reduce the risk of secondary pollution, making the maintenance operation safer and more efficient.
[0038] The carbon canister has a stepped structure that precisely matches the circular box with decreasing dimensions. This ensures the stability of the circular box during installation and avoids sealing failure due to structural misalignment. The top sealing ring 66 at the bottom of the external threaded canister cap 64 and the internal sealing ring of the circular box form a double seal between the canister cap and the canister body, and between the circular box and the inner wall of the carbon canister. This reduces gas leakage points and minimizes the decrease in processing efficiency or safety hazards caused by sealing problems.
[0039] The device is equipped with two independent processing units, carbon canister 1 and carbon canister 2. Gas can be controlled to enter one of the carbon canisters by switching the gas valve 8. The other canister can be used as a backup or maintenance unit, which can ensure that the entire VOC treatment process is uninterrupted. It is especially suitable for industrial scenarios with high requirements for continuous processing.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
