Description

Technical Field

[0001] This utility model relates to the field of gas purification equipment technology, and more specifically, to an activated carbon adsorption device for purifying gases. Background Technology

[0002] With the rapid development of industrial production and the advancement of urbanization, the exhaust gases emitted by industries such as chemical, coating, and printing contain a large amount of volatile organic compounds and harmful particulate matter. These pollutants not only damage the atmospheric environment but also pose potential harm to human health. Activated carbon adsorption, due to its advantages such as high adsorption efficiency, relatively low cost, and simple operation, is widely used in exhaust gas purification equipment.

[0003] The existing structure only has staggered activated carbon layers without baffles, and the gas may flow directly through the gaps between the two layers of activated carbon, resulting in some of the waste gas not being effectively adsorbed. A search revealed that Chinese patent CN219701504U discloses an activated carbon adsorption device. This structure uses two relatively staggered activated carbon layers, with an inclined baffle between them. This splits the gas into two paths at the inlet of each activated carbon adsorption component. One path passes directly through activated carbon layer one for purification, while the other passes through activated carbon layer two, achieving a good purification effect on the waste gas. The relatively staggered arrangement of activated carbon layers one and two reduces the width of the activated carbon box, meeting the installation requirements of actual sites.

[0004] However, in actual use, the activated carbon layer is only fixed by connecting to the side plate. Although there is a baffle to assist in guiding the flow, it may loosen under long-term airflow impact, resulting in uneven airflow distribution and affecting the regularity of the airflow path. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an activated carbon adsorption device for purifying gas, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An activated carbon adsorption device for purifying gas includes an adsorption device housing, one end of which is provided with a waste gas inlet and the other end of which is provided with a clean gas outlet. The interior of the adsorption device housing is provided with a purification mechanism for realizing graded filtration and adsorption of waste gas. The purification mechanism includes a primary filter ring, a left end baffle, an activated carbon interlayer frame, and a right end baffle. The primary filter ring, left end baffle, activated carbon interlayer frame, and right end baffle are arranged sequentially inside the adsorption device housing along the gas flow direction. The primary filter ring is adjacent to the exhaust gas inlet and is detachably threaded inside the adsorption device housing. The left end baffle is located on one side of the primary filter ring and is fixedly connected to the activated carbon interlayer frame. The end of the activated carbon interlayer frame away from the left end baffle is fixedly connected to the right end baffle. The primary filter ring has a mesh structure, and the activated carbon interlayer frame has an upper and lower two-layer structure to increase the contact area with the gas.

[0007] By adopting the above technical solutions: the primary filter ring is designed with a mesh structure and is threaded and detachable, which can not only efficiently intercept large impurities in the exhaust gas, but also facilitate disassembly, cleaning or replacement in the later stage, reducing maintenance difficulty. The activated carbon sandwich frame adopts a two-layer structure, which greatly increases the contact area with the gas, improves the adsorption effect of harmful substances, and makes the purification more thorough. The various components of the purification mechanism are arranged in an orderly manner along the gas flow direction. Together with the pretreatment of the primary filter ring and the deep adsorption of the activated carbon sandwich frame, a graded purification system is formed to ensure the purification accuracy of exhaust gas.

[0008] As a further description of the above technical solution: the surface of the adsorption device housing is provided with a threaded groove at one end of the exhaust gas inlet, a threaded ring is threadedly connected inside the threaded groove, an air inlet pipe is fixedly provided at one end of the threaded ring, and an air outlet pipe is fixedly provided at one end of the clean gas outlet.

[0009] By adopting the above technical solution, it is convenient to open the inlet end for maintenance of internal components such as the primary filter ring and activated carbon interlayer frame, without the need for complicated tools; the threaded connection can also enhance the sealing of the inlet end, preventing waste gas leakage and environmental pollution, while the fixed setting of the outlet pipe ensures the stable discharge of clean gas and guarantees a smooth gas delivery process.

[0010] As a further description of the above technical solution: the inner wall of the adsorption device housing is fixedly provided with two opposing guide strips, one end of the guide strip is fixedly provided with a limiting plate, the guide strip is slidably connected with the right end baffle, and the right end baffle is in contact with the limiting plate. The position of the activated carbon interlayer frame is fixed by the sliding guidance of the guide strip and the positioning of the limiting plate. A fixing frame is fixedly installed on the top of the activated carbon sandwich frame, and an insert plate mesh is inserted into the inside of the fixing frame. The insert plate mesh is used to limit the position of the activated carbon particles. The fixing frame and the insert plate mesh are locked together by bolts to realize the replacement of activated carbon.

[0011] By adopting the above technical solution: the guide strip on the inner wall of the shell slides and the baffle on the right end, and the limiting plate can accurately position the activated carbon interlayer frame, avoiding displacement caused by gas impact and ensuring the stability of the purification path. The top fixing frame of the activated carbon interlayer frame and the insert plate mesh are locked with bolts, which not only prevents the activated carbon particles from being lost with the airflow, but also makes it easy to disassemble the insert plate mesh to replace the activated carbon, thus taking into account both purification stability and maintenance convenience.

[0012] The technical effects and advantages of this utility model are as follows: This utility model adopts a combination structure of threaded detachable primary filter ring and guide sliding activated carbon sandwich frame to solve the problems of cumbersome maintenance and insufficient purification stability of traditional equipment. The primary filter ring has a mesh structure, which can accurately intercept large particles of impurities and avoid clogging of the activated carbon layer. Its threaded connection design allows cleaning and replacement without disassembling the entire shell, improving operational efficiency. The activated carbon sandwich frame is positioned by guide strips and limiting plates. With the upper and lower two-layer structure, it not only ensures a regular gas flow path but also expands the adsorption contact area. The bolt locking design of the insert mesh and the fixed frame prevents the loss of activated carbon particles and ensures uniform gas penetration, achieving efficient purification of waste gas. There is no risk of gas leakage throughout the process, making it suitable for waste gas treatment needs in various industrial and civil scenarios. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1 like Figure 1-5 As shown, this embodiment provides an activated carbon adsorption device for purifying gas, including an adsorption device housing 1, one end of the adsorption device housing 1 is provided with a waste gas inlet 2, the other end of the adsorption device housing 1 is provided with a clean gas outlet 3, and the interior of the adsorption device housing 1 is provided with a purification mechanism for realizing graded filtration and adsorption of waste gas. The purification mechanism includes a primary filter ring 4, a left end baffle 5, an activated carbon interlayer frame 6, and a right end baffle 7. The primary filter ring 4, the left end baffle 5, the activated carbon interlayer frame 6, and the right end baffle 7 are arranged sequentially inside the adsorption device housing 1 along the gas flow direction. The primary filter ring 4 is adjacent to the exhaust gas inlet 2, and the primary filter ring 4 is detachably threaded inside the adsorption device housing 1. The left end baffle 5 is located on one side of the primary filter ring 4, and the left end baffle 5 is fixedly connected to the activated carbon interlayer frame 6. The end of the activated carbon interlayer frame 6 away from the left end baffle 5 is fixedly connected to the right end baffle 7. The right end baffle 7; The primary filter ring 4 has a mesh structure, and the activated carbon interlayer frame 6 has an upper and lower two-layer structure to increase the contact area with the gas.

[0021] As can be seen, in the above technical solution, the primary filter ring 4 is designed as a mesh structure, which can intercept large particulate impurities in the exhaust gas and prevent them from clogging the activated carbon interlayer frame 6, thus extending the activated carbon replacement cycle. At the same time, the primary filter ring 4 adopts a threaded detachable design, which can be disassembled and installed by a single person in just a few minutes. The activated carbon interlayer frame 6 is designed as two layers, which increases the adsorption area compared to a single-layer structure, thereby improving the adsorption efficiency of harmful substances. Furthermore, the purification mechanism is arranged in sequence along the gas flow direction, consisting of four core components: the primary filter ring 4, the left end baffle 5, the activated carbon interlayer frame 6, and the right end baffle 7, forming a graded purification process. This reduces gas short-circuiting and improves purification accuracy. The detachable design of the primary filter ring 4, combined with the double-layer structure of the activated carbon interlayer frame 6, increases the amount of waste gas that the device can process at one time and reduces the cost of replacing parts during maintenance, thus balancing purification performance and economy.

[0022] Usage process: The waste gas to be treated enters the device through the waste gas inlet 2 via the inlet pipe 9, which is threadedly connected to the housing 1 of the adsorption device. The inlet pipe 9 is fixed to the threaded groove on the surface of the housing by the threaded ring 8, and a sealing gasket is provided on the contact surface to ensure the sealing when the gas is introduced and to prevent leakage. After the gas enters the housing 1 of the adsorption device, it flows inward along the preset path and first contacts the first component of the purification mechanism. The gas flows through the primary filter ring 4, which has a mesh structure and can initially intercept large particulate impurities, dust and other pollutants in the exhaust gas. The primary filter ring 4 adopts a threaded and detachable design, so it will not shift due to gas impact during the filtration process, and at the same time, it provides convenience for subsequent cleaning or replacement. Then the pretreated gas passes through the left end baffle 5 and enters the activated carbon interlayer frame 6 area which is fixed and limited by the left end baffle 5 and the right end baffle 7. The right end baffle 7 is slidably connected to the guide strip 11 on the inner wall of the shell and is positioned by the limiting plate 12 to ensure that the activated carbon interlayer frame 6 is in a stable working position and to ensure that the gas flow path is regular. The gas enters the activated carbon sandwich frame 6 with an upper and lower two-layer structure. The filling material can be honeycomb carbon or granular carbon. It is in full contact with the internal filling material, and the harmful substances are adsorbed and removed by the activated carbon. The clean gas that has completed the adsorption and purification passes through the right end baffle 7, through the clean gas outlet 3 at the other end of the adsorption device housing 1, and is discharged from the device through the fixedly set gas outlet pipe 10, thus completing the entire purification process.

[0023] Example 2 like Figure 2 , 4 As shown in Figure 5, this embodiment provides an activated carbon adsorption device for purifying gas, including a threaded groove on the surface of the adsorption device housing 1 at one end of the exhaust gas inlet 2, a threaded ring 8 connected to the inside of the threaded groove, an air inlet pipe 9 fixedly installed at one end of the threaded ring 8, and an air outlet pipe 10 fixedly installed at one end of the clean gas outlet 3. Two opposing guide strips 11 are fixedly installed on the inner wall of the adsorption device housing 1. A limiting plate 12 is fixedly installed at one end of the guide strip 11. The guide strip 11 is slidably connected to the right end baffle 7, and the right end baffle 7 is in contact with the limiting plate 12. The position of the activated carbon interlayer frame 6 is fixed by the sliding guidance of the guide strip 11 and the positioning of the limiting plate 12. A fixed frame 13 is fixedly installed on the top of the activated carbon sandwich frame 6. An insert plate mesh 14 is inserted into the fixed frame 13. The insert plate mesh is used to limit the activated carbon particles. The fixed frame 13 and the insert plate mesh 14 are locked together by bolts 15 to realize the replacement of activated carbon.

[0024] As can be seen, in the above technical solution, the exhaust gas inlet 2 is connected to the intake pipe 9 through the threaded groove and the threaded ring 8. The threaded fit shortens the time required for disassembly and assembly of the intake pipe 9, improves efficiency compared to the traditional welded structure, and improves the sealing of the connection to prevent exhaust gas leakage. The inner wall of the shell is provided with two opposing guide strips 11, which, together with the limiting plate 12, can accurately position the activated carbon interlayer frame 6 to prevent purification deviation caused by displacement and improve the stability of gas flow. The fixed frame 13 and the insert plate mesh 14 are locked together by bolts 15, which makes disassembly and assembly convenient, improves the efficiency of activated carbon replacement, and prevents carbon particle loss.

[0025] Usage process: During later maintenance, unscrew the threaded ring 8 connected to the air intake pipe 9, remove the air intake pipe 9, and then insert it into the adsorption device housing 1. Rotate the primary filter ring 4 counterclockwise because it is connected by threads to remove the primary filter ring 4. If only a small amount of dust is attached to the surface of the primary filter ring 4, use a brush to clean it in the opposite direction along the mesh structure. If the impurities are severely blocked or the primary filter ring 4 is damaged, replace it with a new primary filter ring 4. Then pull the left end baffle 5 outward, causing the right end baffle 7 to slide along the guide strip 11, causing the activated carbon interlayer frame 6 to be removed as a whole. Next, unscrew the bolts 15 on the fixing frame 13, remove the insert mesh 14, pour out the waste activated carbon in the interlayer frame, clean the carbon powder remaining on the inner wall of the interlayer frame with a brush, and then clean or replace the insert mesh 14. Next, evenly fill the activated carbon sandwich frame 6 with new activated carbon, cover it with the insert mesh 14, and use bolts 15 to lock the fixing frame 13 and the insert mesh. Then slide the sandwich frame back to its original position along the guide strip to ensure that the right end baffle is in contact with the limiting plate 12. Then rotate the primary filter ring 4 clockwise into the interior of the adsorption device housing 1 and abut against the left end baffle 5. Then install the air inlet pipe 9 into the exhaust gas inlet 2 of the attached device housing 1.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
