[0002] Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory area. These waste gases carry smoke and dust and pollute the atmosphere when released into the air.

[0003] A search of existing Chinese patent technology reveals a "waste gas treatment device with a multi-layer activated carbon adsorption structure," publication number "CN216320739U." This device, after entering the adsorption filter box through a connecting pipe, has several staggered activated carbon adsorption cotton and filter membranes in the installation cylinder, facilitating multi-layer adsorption filtration of the incoming waste gas and reducing its impact on the surrounding environment. However, during use, the filtration effect gradually decreases due to the filter components coming into contact with impurities, thus affecting the device's service life. Utility Model Content

[0004] Therefore, it is necessary to address the issue that the filtration effect gradually decreases due to the filter components coming into contact with impurities during use, thus affecting the service life of the device. This necessitates providing a waste gas treatment device with an adsorption layer, comprising: an inlet pipe and an outlet pipe, the axes of which coincide; a waste gas treatment mechanism installed between the inlet pipe and the outlet pipe; wherein the waste gas treatment mechanism includes a storage chamber fixedly connected between the inlet pipe and the outlet pipe, the lower end of which is connected to a temporary storage chamber, a filter assembly installed inside the storage chamber extending below the inlet pipe, and an adsorption assembly disposed inside the filter assembly extending above the storage chamber.

[0005] In one embodiment, the filtration assembly includes two lower tubes fixedly connected to the surface of the storage chamber. The two lower tubes are located at the lower ends of the inlet tube and the outlet tube. A central round rod is fixedly connected between the two lower tubes. Two transverse partitions are fixedly connected to the surface of the central round rod. The transverse partitions are fixedly connected to the inner wall of the storage chamber. A second filter screen is provided on one side of the transverse partitions, and a first filter screen is provided on the other side of the transverse partitions.

[0006] In one embodiment, the adsorption assembly includes a top box fixedly connected to the upper end of the storage compartment, a sealing cover snapped onto the upper end of the top box, an adsorption block fixedly connected to the upper wall of the inner wall of the sealing cover, and the lower end of the adsorption block extending into the interior of the storage compartment and contacting the upper end of the partition.

[0007] In one embodiment, two guide strips are fixedly connected to the inner wall of the top box near the partition, and the guide strips on both sides are symmetrically distributed along the center line of the top box.

[0008] In one embodiment, the end of the lower tube is connected to the surface of the storage compartment, and an arc-shaped disc is fixedly connected to the inner wall of the lower tube. The longitudinal cross-section of the arc-shaped disc is arc-shaped, and the material of the arc-shaped disc is elastic rubber.

[0009] In one embodiment, the second filter screen is rotatably connected to the surface of the central round rod near the inlet pipe, and the first filter screen is rotatably connected to the surface of the central round rod near the outlet pipe.

[0012] Beneficial effects

[0013] The aforementioned waste gas treatment device with an adsorption layer can perform preliminary filtration of the waste gas discharged from the inlet pipe by means of the cooperation between the filter components and the storage chamber, reducing the impurities carried in the gas. Furthermore, the second filter screen can contact the liquid inside the storage chamber with the first filter screen, so that the impurities generated by filtration will be separated from the filter screen by the cooperation of the arc-shaped disc and the electric push rod inside the storage chamber and settle in the temporary storage chamber, thereby extending the service life of the device.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The following is combined with Figures 1-5 This invention describes a waste gas treatment device with an adsorption layer.

[0025] In one embodiment, a waste gas treatment device with an adsorption layer includes: an inlet pipe 1 and an outlet pipe 2, the axes of the inlet pipe 1 and the outlet pipe 2 being coincident; a waste gas treatment mechanism 3, the waste gas treatment mechanism 3 being installed between the inlet pipe 1 and the outlet pipe 2; wherein, the waste gas treatment mechanism 3 includes a storage chamber 31 fixedly connected between the inlet pipe 1 and the outlet pipe 2, the lower end of the storage chamber 31 being connected to a temporary storage chamber 311, a filter assembly 32 being installed inside the storage chamber 31, the filter assembly 32 extending below the inlet pipe 1, and an adsorption assembly 33 being disposed inside the filter assembly 32, the adsorption assembly 33 extending above the storage chamber 31;

[0026] It should be noted that after the impurities in the storage chamber 31 are collected by the filter component 32, they will be collected inside the storage chamber 31. The storage chamber 31 contains liquid, and flocculants can be mixed in the liquid to make the impurities settle quickly. The settled flocculent impurities will gather inside the temporary storage chamber 311 under the action of gravity. The temporary storage chamber 311 can be connected to an external pipe body or welded into one piece. When maintenance is required, a positioning cleaning operation can be performed to maintain the good storage function inside the temporary storage chamber 311.

[0027] like Figure 1-4 As shown, the filter assembly 32 includes two lower tubes 321 fixedly connected to the surface of the storage chamber 31. The two lower tubes 321 are located at the lower ends of the inlet tube 1 and the outlet tube 2. A central round rod 322 is fixedly connected between the two lower tubes 321. Two transverse partitions 325 are fixedly connected to the surface of the central round rod 322. The transverse partitions 325 are fixedly connected to the inner wall of the storage chamber 31. A second filter screen 324 is provided on one side of the transverse partition 325, and a first filter screen 323 is provided on the other side of the transverse partition 325.

[0028] The end of the lower tube 321 is connected to the surface of the storage compartment 31. An arc-shaped disc 326 is fixedly connected to the inner wall of the lower tube 321. The second filter screen 324 is rotatably connected to the surface of the middle round rod 322 near the inlet tube 1. The first filter screen 323 is rotatably connected to the surface of the middle round rod 322 near the outlet tube 2. An electric push rod 327 is fixedly connected to the inner wall of one side of the lower tube 321. The telescopic end of the electric push rod 327 is fixedly connected to the surface of the adjacent arc-shaped disc 326.

[0029] In this embodiment, when the device is in use, the exhaust gas discharged from the inlet pipe 1 can be filtered through the second filter 324 and the first filter 323. The mesh size of the first filter 323 is larger than that of the second filter 324. The upper end of the partition plate 325 is provided with multiple water-permeable holes. Liquid is provided below the partition plate 325 and stored inside the storage chamber 31. Since the storage chamber 31 is connected to the lower pipe 321, the liquid fills the lower pipe 321.

[0030] After a period of time, the impurities in the exhaust gas pass through the second filter screen 324 and the first filter screen 323, and can be filtered and intercepted. The operator can manually rotate the filter screen to move the gas filtering area below the liquid surface. The extension end of the electric push rod 327 contacts the arc-shaped disc 326, causing the liquid to vibrate and help the impurities on the filter screen surface to fall off. Rotating it again to reset the filter screen can maintain the filtering effect of the filter screen on the impurities in the exhaust gas.

[0031] like Figure 2 , Figure 3 and Figure 5 As shown, the adsorption assembly 33 includes a top box 331 fixedly connected to the upper end of the storage compartment 31. A sealing cover 332 is snapped onto the upper end of the top box 331. An adsorption block 333 is fixedly connected to the inner top wall of the sealing cover 332. The lower end of the adsorption block 333 extends into the interior of the storage compartment 31 and contacts the upper end of the partition 325. Two guide strips 334 are fixedly connected to the inner wall of the top box 331 near the partition 325. The guide strips 334 on both sides are symmetrically distributed along the center line of the top box 331. Guide plates 335 are fixedly connected to both ends of the adsorption block 333. The guide plates 335 are slidably connected to the surface of the adjacent guide strips 334.

[0032] In this embodiment, the adsorption block 333 can adsorb and filter the exhaust gas. The guide plate 335 and guide strip 334 work together to keep the installation position stable and maintain a good filtration effect on the exhaust gas. This device makes it easy to replace the adsorption block 333. The material of the adsorption block 333 can be a mesh structure. The liquid under the partition plate 325 can improve the adsorption effect of the adsorption block 333. The adsorption block 333 can be made of activated carbon material. The specific material can be adjusted according to the actual use environment.

[0033] Working principle: The second filter screen 324 and the first filter screen 323 filter the exhaust gas discharged from the inlet pipe 1. The upper end of the horizontal partition 325 has multiple water-permeable holes. Liquid is placed below the horizontal partition 325 and stored inside the storage chamber 31. Since the storage chamber 31 is connected to the lower pipe 321, the liquid fills the lower pipe 321. After a period of time, the impurities in the exhaust gas are filtered and intercepted by the second filter screen 324 and the first filter screen 323. The contact area between the filter screen and the exhaust gas moves to below the liquid surface. The extension end of the electric push rod 327 abuts against the arc-shaped disc 326, causing the liquid in the lower pipe 321 to vibrate, which helps the impurities on the surface of the filter screen to fall off. The adsorption block 333 adsorbs and filters the exhaust gas. The cooperation between the guide plate 335 and the guide strip 334 keeps the installation position stable and maintains a good filtration effect on the exhaust gas.

[0034] It should be noted that the electric linear actuator 327 and other devices mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the electric linear actuator 327 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
