[0004] The existing filter structure of the exhaust gas treatment device is fixed and difficult to replace and maintain. Once the filter structure becomes saturated or damaged, it often takes a lot of time and effort to disassemble and reinstall it. Utility Model Content

[0005] To address the problem that the filter structure of existing waste gas treatment devices is fixed and difficult to replace and maintain, this utility model provides a high-efficiency waste gas treatment device.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] An embodiment of this utility model provides a high-efficiency waste gas treatment device, comprising:

[0008] An adsorption box has an air inlet and an air outlet. The adsorption box includes a primary filtration structure and a secondary filtration structure. The primary filtration structure includes a first filter material. The secondary filtration structure includes several activated carbon drawers arranged in an array and activated carbon placed in the activated carbon drawers. The activated carbon drawers are provided with a perforated structure for the passage of exhaust gas. The adsorption box is provided with several placement slots. The activated carbon drawers are slidably installed in the placement slots.

[0009] A fan is installed at the air outlet. The fan is used to create a negative pressure inside the adsorption box so that the exhaust gas enters from the air inlet and passes through the primary filter structure and the secondary filter structure in sequence, and is finally discharged from the air outlet.

[0010] According to some embodiments of the present invention, the adsorption box includes a primary filtration chamber and a secondary filtration chamber, wherein the primary filtration structure is disposed in the primary filtration chamber and the secondary filtration structure is disposed in the secondary filtration chamber.

[0011] According to some embodiments of the present invention, the adsorption box is provided with a door panel for opening and closing the primary filtration chamber.

[0012] According to some embodiments of the present invention, the placement groove is connected to the secondary filtration chamber and the placement groove penetrates the outer surface of the adsorption box, and the activated carbon drawer can be pulled out and slid in the placement groove and can isolate the secondary filtration chamber.

[0013] According to some embodiments of the present invention, the adsorption box further includes a first partition plate disposed between the primary filtration chamber and the secondary filtration chamber. The first partition plate is disposed in the middle of the adsorption box. An upper air duct is formed between the top of the first partition plate and the inner top wall of the adsorption box, and a lower air duct is formed between the bottom of the first partition plate and the inner bottom wall of the adsorption box. The upper air duct and the lower air duct are respectively connected to the secondary filtration chamber.

[0014] According to some embodiments of the present invention, a second partition is further provided in the secondary filtration chamber.

[0027] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0030] Embodiments of this utility model provide a high-efficiency waste gas treatment device, such as... Figure 1-6 As shown, it includes:

[0031] The adsorption box 100 has an air inlet 101 and an air outlet 102. The adsorption box 100 includes a primary filtration structure 110 and a secondary filtration structure 120. The primary filtration structure 110 includes a first filter material 112. The secondary filtration structure 120 includes several activated carbon drawers 122 arranged in an array and activated carbon placed in the activated carbon drawers 122. The activated carbon drawers 122 are provided with a hollow structure 123 for the passage of exhaust gas. The adsorption box 100 is provided with several placement slots 105. The activated carbon drawers 122 are slidably installed in the placement slots 105.

[0032] Fan 200 is installed at air outlet 102. Fan 200 is used to create negative pressure in adsorption box 100 so that exhaust gas enters from air inlet 101 and passes through primary filter structure 110 and secondary filter structure 120 in sequence, and is finally discharged from air outlet 102.

[0033] The adsorption box 100 is used for filtering and adsorbing waste gas. Waste gas enters the adsorption box 100 through the inlet 101, and after treatment, is discharged through the outlet 102. The primary filtration structure 110 uses a first filter material 112, which can be activated carbon or filter cotton, etc., mainly used to filter large particulate impurities or preliminary pollutants in the waste gas, playing a pretreatment role and reducing the burden on subsequent treatment processes.

[0034] The secondary filtration structure 120 consists of several activated carbon drawers 122, each containing activated carbon. Activated carbon is a material with a high specific surface area and adsorption capacity, effectively adsorbing harmful gases (such as organic matter and odors) in waste gas. The activated carbon drawers 122 are arranged in an array and have a perforated structure 123 to allow waste gas to pass through. This design ensures that the waste gas can fully contact the activated carbon and facilitates the replacement and maintenance of the activated carbon. The adsorption box 100 has several placement slots 105, and the activated carbon drawers 122 are slidably installed in the placement slots 105. This pull-out design facilitates the installation, replacement, and cleaning of the activated carbon drawers 122, improving the maintenance convenience of the device. By adopting a two-stage filtration structure, the primary filtration structure 110 intercepts large particulate impurities, while the secondary filtration structure 120 adsorbs harmful gases through activated carbon, effectively improving the efficiency of waste gas treatment. The pull-out design of the activated carbon drawers 122 facilitates the replacement and maintenance of the activated carbon, reducing maintenance costs and time. An adsorption box 100 is equipped with a placement slot 105, which makes the installation of the activated carbon drawer 122 more stable. At the same time, the fan 200 is located at the air outlet 102, which can effectively form negative pressure and ensure the smooth flow of exhaust gas.

[0035] The fan 200 is located at the air outlet 102. The fan 200 creates a negative pressure inside the adsorption box 100 by drawing air. The formation of the negative pressure drives the exhaust gas from the air inlet 101 into the adsorption box 100, and through the primary filtration structure 110 and the secondary filtration structure 120 in sequence, ultimately causing the purified exhaust gas to be discharged from the air outlet 102.

[0036] The working principle of this utility model is as follows:

[0037] like Figure 2 As shown, the exhaust gas enters through the inlet 101 of the adsorption box 100. First, it passes through the primary filtration structure 110, where large particles or initial pollutants are intercepted by the first filter material 112. Then, the exhaust gas enters the secondary filtration structure 120, where it undergoes adsorption treatment by the activated carbon in the activated carbon drawer 122. The high adsorption performance of the activated carbon effectively removes harmful gases and odors from the exhaust gas. After two stages of filtration, the exhaust gas is discharged from the outlet 102 under the action of the fan 200, achieving the purpose of purifying the exhaust gas.

[0038] In some embodiments, the adsorption box 100 includes a primary filtration chamber 111 and a secondary filtration chamber 121, with the primary filtration structure 110 disposed in the primary filtration chamber 111 and the secondary filtration structure 120 disposed in the secondary filtration chamber 121.

[0039] The primary filtration chamber 111 is mainly used for preliminary filtration of exhaust gas. The primary filtration chamber 111 contains a primary filtration structure 110, including a first filter material 112. This design ensures that after exhaust gas enters the adsorption box 100, it first passes through the primary filtration chamber 111, where large particulate impurities or preliminary pollutants are intercepted, serving a pretreatment function. Through preliminary filtration, the impurity content in the exhaust gas entering the secondary filtration chamber 121 can be effectively reduced, extending the service life of the secondary filtration structure 120 (activated carbon). The interception of large particulate impurities by the primary filtration structure 110 prevents these impurities from clogging the perforated structure 123 of the activated carbon drawer 122, thereby ensuring that exhaust gas can smoothly pass through the secondary filtration structure 120.

[0040] The secondary filtration chamber 121 is mainly used for deep purification of the exhaust gas after preliminary filtration. The secondary filtration chamber 121 is equipped with a secondary filtration structure 120, including several activated carbon drawers 122 arranged in an array and activated carbon placed inside the drawers 122. The activated carbon drawers 122 have a perforated structure 123 for the exhaust gas to pass through and are slidably installed in the placement slot 105.

[0041] Furthermore, the adsorption box 100 is provided with a door panel 104 for opening and closing the primary filtration chamber 111.

[0042] The adsorption box 100 is equipped with a door panel 104 for opening and closing the primary filtration chamber 111. The main function of the door panel 104 is to facilitate the maintenance, replacement, or inspection of the primary filtration structure 110 inside the primary filtration chamber 111 by the operator. The adsorption box 100 includes an outer shell 103, which serves as the external frame of the adsorption box 100 and protects the internal primary filtration structure 110 and secondary filtration structure 120 from damage caused by the external environment (such as dust, rain, mechanical impact, etc.).

[0043] Furthermore, the placement slot 105 is connected to the secondary filtration chamber 121 and the placement slot 105 extends through the outer surface of the adsorption box 100. The activated carbon drawer 122 can be pulled out and slid in the placement slot 105 and can isolate the secondary filtration chamber 121.

[0044] The placement slot 105 is connected to the secondary filtration chamber 121, ensuring that the waste gas can smoothly enter the activated carbon drawer 122 from the secondary filtration chamber 121 for adsorption treatment. The placement slot 105 extends through the outer surface of the adsorption box 100. This design allows the activated carbon drawer 122 to be directly pulled out from the outer surface of the adsorption box 100, facilitating maintenance and replacement of activated carbon by operators. Operators do not need to enter the adsorption box 100; they can simply pull out the activated carbon drawer 122 through the operating port on the outer surface of the adsorption box 100, greatly improving maintenance convenience. After being pushed into the placement slot 105, the activated carbon drawer 122 tightly isolates the secondary filtration chamber 121, ensuring that the waste gas flows along a predetermined path within the secondary filtration chamber 121, improving adsorption efficiency. A sealing gasket or sealing strip can be used between the activated carbon drawer 122 and the placement slot 105 to ensure that no waste gas leakage occurs during operation.

[0045] In some embodiments, the adsorption box 100 further includes a first partition 106 disposed between the primary filtration chamber 111 and the secondary filtration chamber 121. The first partition 106 is disposed in the middle of the adsorption box 100. An upper air duct is formed between the top of the first partition 106 and the inner top wall of the adsorption box 100, and a lower air duct is formed between the bottom of the first partition 106 and the inner bottom wall of the adsorption box 100. The upper air duct and the lower air duct are respectively connected to the secondary filtration chamber 121.

[0046] like Figure 3 As shown, the first partition 106 is located in the middle of the adsorption box 100, dividing the outlet of the primary filtration chamber 111 into an upper air duct and a lower air duct. This design allows the exhaust gas after primary filtration to be distributed into the two air ducts. This distribution helps to improve the adsorption efficiency of the activated carbon drawer 122 and avoids local overloading of activated carbon while other parts are not fully utilized. Distributing the exhaust gas ensures that the activated carbon drawer 122 in the secondary filtration chamber 121 can more effectively contact the harmful substances in the exhaust gas, thereby improving the overall purification effect.

[0047] Furthermore, a second partition 107 is provided inside the secondary filtration chamber 121. The second partition 107 is located at the outlet of the secondary filtration chamber 121. The air outlet 102 is located in the middle of the adsorption box 100. The second partition 107 is provided with an air outlet groove 108 that connects with the air outlet 102. The placement groove 105 is located between the first partition 106 and the second partition 107.

[0048] like Figure 3 As shown, the second baffle 107 is located at the outlet of the secondary filtration chamber 121, optimizing the flow path of the exhaust gas within the secondary filtration chamber 121. By providing an outlet slot 108 that connects to the outlet 102, the second baffle 107 ensures that the exhaust gas treated by the activated carbon drawer 122 can be evenly discharged from the outlet 102. The design of the second baffle 107 prevents exhaust gas that has not been adequately adsorbed from being directly discharged from the outlet 102. By guiding the exhaust gas through the activated carbon drawer 122 for thorough adsorption, it ensures that harmful substances in the exhaust gas are removed to the maximum extent.

[0049] In some embodiments, the adsorption box 100 is further provided with a sliding groove 115, which is used to install the primary filter structure 110.

[0050] The design of the sliding groove 115 makes the installation and replacement of the primary filter structure 110 more convenient and quick. Operators can easily push the primary filter structure 110 in or out using the sliding groove 115, without complicated disassembly and installation steps. Since the primary filter structure 110 is mainly used to intercept large particulate impurities in exhaust gas, its replacement frequency may be relatively high. The design of the sliding groove 115 greatly reduces maintenance time and labor intensity, improving the overall operating efficiency of the unit.

[0051] The sliding groove 115 is located inside the primary filtration chamber 111 and is used to install the primary filtration structure 110. The sliding groove 115 is typically designed on the inner wall of the adsorption box 100 and matches the shape and size of the primary filtration structure 110. The sliding groove 115 can be designed as a linear sliding or track sliding type to ensure that the primary filtration structure 110 can be smoothly pushed in and pulled out.

[0052] Furthermore, the primary filtration structure 110 includes an installation mesh 113, which can slide into the adsorption box 100 along the sliding groove 115.

[0053] The mounting net 113 is used to fix and support the first filter material 112. In this embodiment, the first filter material 112 is filter cotton. It provides a stable frame for the filter cotton, ensuring that the filter cotton will not shift or deform when exhaust gas passes through. The mounting net 113 is designed to slide in and out of the adsorption box 100 along the sliding groove 115, making the installation and replacement of the filter cotton more convenient and quick. Operators do not need to enter the adsorption box 100; they can simply push the mounting net 113 in or pull it out through the sliding groove 115 to complete the replacement. The filter cotton is installed inside the mounting net 113 and can be fixed to the mounting net 113 by means of clips, screws, or adhesives, ensuring that it will not loosen during operation.

[0054] In some embodiments, the first filter material 112 is an activated carbon plate 114, which can slide into the adsorption box 100 along the sliding groove 115.

[0055] The activated carbon plate 114 not only intercepts large particulate impurities in the exhaust gas (similar to the function of filter cotton), but also adsorbs some harmful gases and odors in the exhaust gas. This design allows the primary filtration stage to go beyond physical interception and perform preliminary chemical adsorption, further purifying the exhaust gas. By introducing the activated carbon plate 114 into the primary filtration stage, some harmful gases can be adsorbed in advance, reducing the concentration of pollutants entering the secondary filtration chamber (activated carbon drawer 122), thereby extending the service life of the secondary filtration structure 120 and reducing maintenance costs.

[0056] In some embodiments, the hollow structure 123 is a plurality of elongated grooves 124 disposed on both sides or at the bottom of the activated carbon drawer 122.

[0057] The hollow structure 123 (long groove 124) provides a uniform flow channel for the exhaust gas, allowing it to pass more smoothly through the activated carbon drawer 122 and avoiding obstructed flow due to local blockages. The design of the long groove 124 increases the contact area between the exhaust gas and the activated carbon, ensuring that harmful substances in the exhaust gas can be more fully adsorbed by the activated carbon, thereby improving the purification effect.

Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
