Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon adsorption devices, and particularly relates to a multi-layer activated carbon adsorption device for waste gas treatment. Background Art

[0002] An activated carbon adsorption device is a device that uses the adsorption performance of activated carbon to treat pollutants in gases or liquids.

[0003] An activated carbon adsorption device usually consists of the following parts:

[0004] Adsorption bed: filled with activated carbon particles or activated carbon fibers, which is the main area for adsorbing pollutants;

[0005] Outer shell: used to accommodate the adsorption bed and protect the internal structure;

[0006] Inlet and outlet: used to introduce the gas or liquid to be treated and discharge the treated gas or liquid respectively;

[0007] Filter component: at the inlet, used to preliminarily filter larger impurities and protect the adsorption bed;

[0008] The working principle of the activated carbon adsorption device is that when the gas or liquid containing pollutants passes through the adsorption bed, the pollutant molecules are adsorbed by the pores on the surface of the activated carbon, so as to achieve the purpose of purification;

[0009] However, most of the above-mentioned filter components only adopt a single-layer or simple filtering method, which is difficult to effectively remove various pollutants in the waste gas, resulting in the treated waste gas may still cause certain harm to the environment. During the contact process between the waste gas and the filter material, due to the lack of effective agitation and uniform distribution measures, the contact between the waste gas and the filter material is not sufficient and uniform, affecting the adsorption effect and treatment efficiency. In addition, the filter material is prone to blockage after long-term use, which not only reduces the filtering effect, but also requires frequent replacement or cleaning of the filter material, increasing the operating cost and maintenance workload.

[0034] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the technical solution in the embodiment of the present application effectively solves the technical problems that most of the existing filtering components only adopt a single layer or a simple filtering method, making it difficult to effectively remove various pollutants in the waste gas, resulting in the treated waste gas still possibly causing certain harm to the environment. During the contact process between the waste gas and the filtering material, due to the lack of effective agitation and uniform distribution measures, the contact between the waste gas and the filtering material is not sufficient and uniform, affecting the adsorption effect and treatment efficiency. In addition, the filtering material is prone to clogging after long-term use, which not only reduces the filtering effect but also requires frequent replacement or cleaning of the filtering material, increasing the operating cost and maintenance workload.

After filtration, the exhaust gas passes through the three-layer filtration. The exhaust gas is discharged through the exhaust pipe 33, and at the same time, the driving motor 24 can be started. Under the action of the driving motor 24, the rotating column 25 will be driven to rotate, and the rotation of the rotating column 25 will drive the stirring blade 26 to rotate accordingly, thereby stirring the exhaust gas inside the adsorption box 11, so that the exhaust gas and the first activated carbon adsorption plate 17 are more evenly contacted, which can enhance the adsorption effect, and when the rotating column 25 is rotating, it will also drive the baffle 27 to rotate accordingly, and the rotation of the two baffles 27 will squeeze the first activated carbon adsorption plate 17, and the first activated carbon adsorption plate 17 will be compressed by the squeezing force, and every time the baffle 27 rotates around the rotating column 25, the first activated carbon adsorption plate 17 will shake up and down once, so that the first activated carbon adsorption plate 17 is not easy to be blocked when adsorbing exhaust gas, which further enhances the adsorption effect of the equipment;

The two insertion strips 35 are rotatably installed with a turning column 36 inside, and the two turning columns 36 are threadedly installed with a threaded ring 37. When in use, the exhaust pipe can be connected to the lower end of the adsorption box 11 first, and then the first activated carbon adsorption plate 17 can be placed in the placement groove 13.

[0038] In response to the problems existing in the prior art, the utility model provides a multi-layer activated carbon adsorption device for waste gas treatment. The equipment adopts a multi-layer filtering structure, which significantly improves the filtering effect of waste gas, effectively removes harmful substances and reduces pollution to the environment. The equipment adopts a unique stirring and shaking design to make the contact between the waste gas and the filtering component more uniform, enhance the adsorption effect, avoid clogging of the filtering component, and extend the service life and maintenance cycle of the equipment.

[0039] Working principle:

[0040] In the first step, when in use, the exhaust pipe can be connected to the lower end of the adsorption box 11, and then the first activated carbon adsorption plate 17 can be placed in the placement groove 13. At this time, the cover plate 31 can be placed above the adsorption box 11. At this time, the two extrusion strips 34 on the cover plate 31 will complete the resistance and compression of the two second activated carbon adsorption plates 19. At the same time, the two insertion strips 35 will be inserted into the two inner grooves 15. At this time, the two flip columns 36 can be rotated on the two insertion strips 35. Under the rotation of the two flip columns 36, they will be respectively stuck in the two arc grooves 16, and then the two threaded rings 37 on the two flip columns 36 will be rotated to complete the fixation, so that the overall installation and disassembly of the device is more convenient and labor-saving when in use;

[0041] In the second step, after installation, the suction pump 32 can be started. Under the action of the suction pump 32, the exhaust gas inside the adsorption box 11 will be sucked out, and the exhaust gas will be filtered through the first activated carbon adsorption plate 17, the second activated carbon adsorption plate 19 and the third activated carbon adsorption plate 23. After filtering, it will be discharged through the outlet pipe 33. At the same time, the drive motor 24 can be started. Under the action of the drive motor 24, the rotating column 25 will be driven to rotate, and the rotation of the rotating column 25 will drive the stirring blade 26 to rotate accordingly, thereby stirring the exhaust gas inside the adsorption box 11, so that the exhaust gas and the first activated carbon adsorption plate 17 and the second activated carbon adsorption plate 19 and the third activated carbon adsorption plate 23 are mixed. The contact of the activated carbon adsorption plate 17 is more uniform, which can enhance the adsorption effect, and when the rotating column 25 rotates, the baffle 27 will also be driven to rotate. The rotation of the two baffles 27 will squeeze the first activated carbon adsorption plate 17, and the first activated carbon adsorption plate 17 will be compressed by the extrusion force, and every time the baffle 27 rotates around the rotating column 25, the first activated carbon adsorption plate 17 will shake up and down, making it difficult for the first activated carbon adsorption plate 17 to be blocked when adsorbing exhaust gas, further enhancing the adsorption effect of the equipment.
