Description

Technical Field

[0001] This utility model relates to the field of activated carbon adsorption treatment technology for VOCs, and in particular to a VOCs activated carbon adsorption treatment device. Background Technology

[0002] VOCs activated carbon is an activated carbon material specifically designed for adsorbing volatile organic compounds. It is mainly used in the treatment of industrial waste gas in chemical, pharmaceutical, and coating industries, as well as in indoor air purification. It uses wood-based columnar activated carbon as a base and features a large specific surface area and a high adsorption efficiency of 85%-99.99%, with a carbon tetrachloride adsorption rate of 100%.

[0003] After a period of use, activated carbon adsorption of VOCs is prone to local adsorption saturation, which leads to a decrease in overall adsorption efficiency. In this process, a VOCs activated carbon adsorption treatment device is needed to treat the activated carbon.

[0004] Traditional VOCs activated carbon adsorption treatment devices require production to be shut down when the activated carbon is replaced, which affects the continuity of production. Furthermore, when treating VOCs waste gas with complex composition and large concentration fluctuations, a single adsorption mode is difficult to achieve both high-efficiency adsorption and economical operation.

[0005] Therefore, it is necessary to provide a VOCs activated carbon adsorption treatment device to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides a VOCs activated carbon adsorption treatment device, which solves the problems of poor adsorption effect of VOCs activated carbon adsorption treatment devices with single adsorption mode and the need to stop production when replacing activated carbon, affecting the continuity of production.

[0007] To solve the above-mentioned technical problems, the VOCs activated carbon adsorption treatment device provided by this utility model includes: a support component;

[0008] An adsorption tube is fixedly connected to the top of a support assembly. A processing frame and a placement frame are respectively installed on the front and back of the adsorption tube via a connecting structure. Each processing frame and placement frame has an opening at its top. An adjustment assembly is installed on the top of the processing frame and placement frame. A movable frame is installed at the bottom of the adjustment assembly. Multiple sealing frames are provided on the outer surface of the movable frame. Two installation ports are opened on one side of the movable frame. An activated carbon adsorption structure is installed inside each installation port. The activated carbon adsorption structure includes a core adsorption layer, an auxiliary adsorption layer, and a protective buffer layer. The auxiliary adsorption layer is located between the core adsorption layer and the protective buffer layer. A nitrogen storage structure and a recovery and storage structure are respectively installed near both ends of the top of the adsorption tube. A recovery structure and a filtration structure are installed on the top of the recovery and storage structure. A conveying structure is installed on the top of the nitrogen storage structure. A sealing cap is installed at the opposite ends of the processing frame and placement frame.

[0009] A heating structure is installed on one side of a processing frame, a gas supply structure is installed on one side of the processing frame, and a gas suction structure is installed on the other side of the processing frame.

[0010] The movable frame moves between the adsorption tube, the treatment frame, and the placement frame. Both the front and back of the adsorption tube have openings for the movable frame to move. A sealing frame on the outer surface of the movable frame enhances the sealing of the connections, ensuring no leakage at the adsorption tube openings during movement. The core adsorption layer is filled with honeycomb activated carbon with a high specific surface area, characterized by low resistance and fast adsorption rate. It is mainly used for the rapid adsorption of high-concentration large-molecule VOCs in waste gas, such as benzene compounds and esters. The auxiliary adsorption layer is filled with a composite of granular activated carbon and molecular sieves. The molecular sieves selectively adsorb small-molecule VOCs and some moisture, working synergistically with the granular activated carbon to further purify the waste gas and reduce moisture content. The effect of temperature on adsorption is considered. The protective buffer layer is filled with coarse-porous activated carbon for preliminary filtration of particulate matter in the waste gas, buffering the airflow impact and protecting the internal adsorption layer. The recovery structure and the conveying structure are both composed of a shell and a gas conveying pump. The filtration structure includes a shell and a structure for filtering impurities. When the treatment frame is subjected to nitrogen and high-temperature treatment, the suction structure and the gas supply structure work simultaneously, and only a small amount of nitrogen will be discharged from the active port. During this process, a rubber pad can be used to cover the active port. The adsorption property of the rubber can ensure that the position of the active port is relatively sealed. Combined with the suction structure, this can ensure that nitrogen does not leak. After the treatment is completed, the rubber pad can be removed without affecting the movement of the internal thread frame.

[0011] Preferably, both ends of the adsorption tube are equipped with docking structures, and an interception component is installed inside one of the docking structures;

[0012] The interceptor is installed at the inlet end of the adsorption tube and can filter out larger particles of impurities.

[0013] Preferably, the support assembly includes a base plate and a bracket, and an operation panel is mounted on one side of the placement frame;

[0014] The control panel allows you to set the device's operating parameters.

[0015] Preferably, a control box is mounted on the top of the support assembly, and a door is rotatably connected to one side of the control box;

[0016] The control box is equipped with a lock on the door, and the inside of the control box contains power switches and controllers for the operation of auxiliary equipment.

[0017] Preferably, the adjustment assembly includes two fixing brackets, a drive assembly, two internal threaded brackets, an adjusting screw and a slide bar. The two fixing brackets are used to install the adjusting screw and slide bar above the processing frame, the adsorption tube and the placement frame. The internal threaded brackets are installed on the outer surface of the adjusting screw and slide bar.

[0018] The drive assembly is mounted on one side of one of the fixed brackets to provide rotational drive force for the adjusting screw, and the internal thread bracket and slide bar are slidably connected.

[0019] Preferably, the drive assembly includes a protective housing, an angle sensor, and a drive component, wherein the protective housing is used to mount the drive component that provides rotational driving force.

To improve the VOCs activated carbon adsorption treatment effect and replacement efficiency, a treatment frame and a placement frame are respectively installed on the front and back of the adsorption tube via a connecting structure. An opening is provided at the connection between the adsorption tube and the treatment and placement frames to allow the movable frame to move. The outer surface of the movable frame is sealed by a sealing frame to ensure the airtightness of the connection. Then, two activated carbon adsorption structures, each consisting of a core adsorption layer, an auxiliary adsorption layer, and a protective buffer layer, are installed in the two installation openings on the movable frame. An adjustment component is installed on the top of the adsorption tube to move the movable frame between the adsorption tube, the treatment frame, and the placement frame. This design allows two activated carbon adsorption structures to work alternately. Under the premise of ensuring airtightness, the activated carbon adsorption structures can be cleaned or replaced without stopping production. The operation is simple. At the same time, the layers are connected by a specially designed gas distributor to ensure that the waste gas passes through each layer evenly, thereby improving the adsorption efficiency.

[0043] The working principle of the VOCs activated carbon adsorption treatment device provided by this utility model is as follows:

[0044] A processing frame 5 and a placement frame 9 are respectively installed on the front and back of the adsorption tube 6 via a connecting structure 7. An opening is provided at the connection point between the adsorption tube 6 and the processing frame 5 and placement frame 9 to allow the movable frame 24 to move.

After that, the heating structure 20 is activated to heat the activated carbon. Once the corresponding temperature is reached, the conveying structure 18 is activated to inject nitrogen into the processing frame 5 through the gas supply structure 19 to desorb the VOCs adsorbed on the activated carbon adsorption structure 21. During this process, the recovery structure 16 generates suction, which, together with the filtration structure 17, recovers and stores the nitrogen for later processing and reuse. The activated carbon adsorption structure 21 that has been processed will be reset. During this process, the activated carbon adsorption structure 21 that takes over the work will move into the placement frame 9. When replacement is needed, the sealing cover 4 can be opened to replace the activated carbon adsorption structure 21 inside the processing frame 5 or the placement frame 9.
