Abstract
Description
Technical Field
[0001] This utility model relates to the field of adsorption devices, and in particular to an adsorption device for purifying volatile organic waste gas. Background Technology
[0002] VOC emissions from industrial production pose a serious threat to the environment and human health. VOCs mainly come from industries such as chemical, printing, and coating. Their emissions not only pollute the air but may also lead to secondary pollution such as photochemical smog. In actual use, when the humidity content in the exhaust gas is high, the adsorbent will preferentially adsorb moisture. To solve this problem, a dehumidification structure is added to pre-treat the exhaust gas during adsorption treatment. However, the existing dehumidification methods still have shortcomings.
[0003] In existing technologies, adsorption devices for purifying volatile organic compounds (VOCs) typically incorporate a dehumidification mechanism before the adsorption unit to reduce the moisture content entering the unit and prevent the adsorbent from preferentially adsorbing moisture from the waste gas during subsequent adsorption, thus affecting the final adsorption effect. However, during use, some particulate matter originally suspended in the waste gas will enter the condensate water along with the condensation of water vapor. These particulate matter may contain harmful substances such as heavy metals and organic pollutants. Their presence transforms the condensate water from ordinary water into a potentially hazardous wastewater. Directly discharging this particulate-containing condensate water would undoubtedly harm the environment. Therefore, it is necessary to improve the adsorption device for purifying VOCs to address these issues. Utility Model Content
[0004] To overcome the problem that when dehumidification systems pre-treat exhaust gases, some particulate matter mixes with condensate, and the particulate matter is discharged with the condensate, causing environmental pollution.
[0005] The technical solution of this utility model is as follows: an adsorption device for purifying volatile organic waste gas, including a mounting base, an air inlet, and a purification mechanism. A mounting frame is fixedly connected to the top of the mounting base, and the purification mechanism is located on the top of the mounting base.

A first limiting block is fixedly connected inside the first fixed box, and a first sliding frame is slidably connected to the inner side of the first limiting block. A pre-filter plate body and a dust filter plate body are located inside the first sliding frame. An activated carbon filter plate is located inside the pre-filter plate body. A drainage pipe is fixedly connected to the bottom of the first fixed box.
[0006] Preferably, three first sliding frames are provided, which are sequentially connected to the inner side of the first limiting block in the upper, middle and lower positions. The pre-filter plate body, the dust filter plate body and the activated carbon filter plate are respectively arranged inside the three first sliding frames.
[0007] Preferably, a rotating rod is rotatably connected inside the first sliding frame, and a sliding plate is threadedly connected to the outside of the rotating rod, with the sliding plate slidably connected inside the first sliding frame.
[0008] Preferably, the first sliding frame has a rotating groove at the relative position of the rotating rod, and the rotating rod is rotatably connected inside the rotating groove.
[0009] Preferably, the purification mechanism includes a second fixed box, which is fixedly connected to the top of the mounting base. A second limiting block is fixedly connected inside the second fixed box, and an activated carbon adsorbent placement shelf is slidably connected to the inner side of the second limiting block. A fixing buckle is fixedly connected to the front of the second fixed box, and a rotating plate is rotatably connected to the fixing buckle. A sealing gasket is fixedly connected to the rotating plate. A fixing block is fixedly connected to the front of the second fixed box, and a snap-fit block is slidably connected inside the fixing block. The snap-fit block is snap-fitted inside the rotating plate. A first spring is fixedly connected between the snap-fit block and the fixing block.

[0010] Preferably, the guide block has a limiting groove at the relative position of the fixed rod, and the guide block is slidably connected inside the limiting groove.
[0011] Preferably, the conveying pipe has a groove at the relative position of the sliding rack, and the sliding rack is slidably connected inside the groove.
[0012] The beneficial effects of this utility model are:
[0013] 1. After the exhaust gas is dehumidified by the condenser body, it is filtered by the pre-filter plate body, the dust filter plate body and the activated carbon filter plate before being discharged. The dehumidified water is thoroughly filtered, and particulate matter in the water is intercepted and removed step by step, which greatly improves the cleanliness of the water and avoids the impact of particulate matter on the environment when discharged with condensate. This avoids the problem that some particulate matter will mix with condensate when the dehumidification mechanism pre-treats the exhaust gas, and then the particulate matter will be discharged with the condensate, causing environmental pollution.
[0014] 2. By cooperating with the sliding rack and rotating gear, the grid blades are driven to rotate back and forth, so that the exhaust gas entering the second fixed box is more evenly guided to the activated carbon adsorbent placement plate, avoiding excessive local adsorption after the exhaust gas enters in a concentrated manner.

Detailed Implementation
[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0026] Please see Figure 1 - Figure 5This utility model provides an embodiment of an adsorption device for purifying volatile organic waste gas, including a mounting base 1, an air inlet 21, and a purification mechanism. A mounting frame 4 is fixedly connected to the top of the mounting base 1, and the purification mechanism is located on the top of the mounting base 1. The air inlet 21 is fixedly connected to the mounting frame 4, and an air inlet grille 22 is fixedly connected inside the air inlet 21. A first fixed box 23 is fixedly connected to the top of the mounting base 1, and a conveying pipe 24 is fixedly connected to the first fixed box 23. A suction fan body 25 is located inside the conveying pipe 24. A condenser body 26 is located inside the first fixed box 23, and a first limiting device is fixedly connected inside the first fixed box 23. The first limiting block 27 has a first sliding frame 28 slidably connected to its inner side. A pre-filter plate body 29 and a dust filter plate body 210 are installed inside the first sliding frame 28. An activated carbon filter plate 211 is installed inside the pre-filter plate body 29. A drain pipe 212 is fixedly connected to the bottom of the first fixed box 23. During use, the exhaust fan body 25 operates, causing exhaust gas to enter the first fixed box 23 through the air intake grille 22 and air intake 21. Inside the first fixed box 23, the exhaust gas passes through the condenser body 26, where the condenser body 26 condenses the moisture inside, causing it to fall to the first sliding frame 28. After three... After filtration by the pre-filter plate body 29, dust filter plate body 210, and activated carbon filter plate 211 inside the first sliding frame 28, the exhaust gas is discharged through the drain pipe 212. After dehumidification by the condenser body 26, the exhaust gas is transported to the purification mechanism for further purification through the conveying pipe 24. Three first sliding frames 28 are provided, and these three frames are sequentially slidably connected to the inner side of the first limiting block 27. The pre-filter plate body 29, dust filter plate body 210, and activated carbon filter plate 211 are respectively located inside the three first sliding frames 28. The exhaust gas is filtered by the three first sliding frames 28 and the pre-filter plate body 29, dust filter plate body 210, and activated carbon filter plate 211 located inside them. The filter plate 211 filters water thoroughly before discharging it to avoid environmental impact. A rotating rod 213 is rotatably connected inside the first sliding frame 28, and a sliding plate 214 is threadedly connected to the outside of the rotating rod 213. The sliding plate 214 is slidably connected inside the first sliding frame 28. Rotating the rotating rod 213 drives the sliding plate 214 to slide, thereby releasing the restriction on the filter plate, which facilitates subsequent replacement and cleaning, making maintenance more convenient. A rotating groove is opened in the first sliding frame 28 at the relative position of the rotating rod 213. The rotating rod 213 is rotatably connected inside the rotating groove. The rotating groove restricts the rotation of the rotating rod 213 to prevent the rotating rod 213 from moving and affecting the sliding of its sliding plate 214.
[0027] Please see Figure 2 , Figure 6 - Figure 9In this embodiment, the purification mechanism includes a second fixed box 31, which is fixedly connected to the top of the mounting base 1. A second limiting block 32 is fixedly connected inside the second fixed box 31, and an activated carbon adsorbent placement shelf 33 is slidably connected to the inner side of the second limiting block 32. A fixing buckle 34 is fixedly connected to the front of the second fixed box 31, and a rotating plate 35 is rotatably connected to the fixing buckle 34. A sealing gasket 36 is fixedly connected to the rotating plate 35. A fixing block 37 is fixedly connected to the front of the second fixed box 31, and the interior of the fixing block 37... A sliding connection includes a snap-fit block 38, which snaps into the interior of the rotating plate 35. A first spring 39 is fixedly connected between the snap-fit block 38 and the fixing block 37. A first motor 310 is fixedly connected to the back of the conveying pipe 24. A rotating disk 311 is fixedly connected to the output end of the first motor 310. A fixing rod 312 is fixedly connected to the rotating disk 311. A sliding rack 313 is slidably connected to the back of the conveying pipe 24. A guide block 314 is fixedly connected to the sliding rack 313. The fixing rod 312 is slidably connected to the guide block 314. Inside, the sliding rack 313 is externally engaged with a rotating gear 315. A grid blade 316 is fixedly connected inside the rotating gear 315. The grid blade 316 is rotatably connected inside the conveying pipe 24. A first spring 39 provides thrust to the locking block 38, pushing the locking block 38 to more securely engage inside the rotating plate 35, thus restricting the rotating plate 35. This ensures that the sealing gasket 36 fits snugly against the gap between it and the second fixed box 31, preventing exhaust gas leakage and its impact on the surrounding environment. The guide block 314 is positioned relative to the fixed rod 312. A limiting groove is provided at the position, and the guide block 314 is slidably connected inside the limiting groove. The limiting groove restricts the sliding of the fixed rod 312, preventing the fixed rod 312 from disengaging from the guide block 314 when it slides, thus affecting its ability to drive the sliding rack 313 to slide. The conveying pipe 24 has a sliding groove at the relative position of the sliding rack 313, and the sliding rack 313 is slidably connected inside the sliding groove. The sliding groove restricts the sliding of the sliding rack 313, allowing the sliding rack 313 to slide linearly inside the sliding groove, preventing it from tilting and affecting its meshing with the rotating gear 315.
[0028] During operation, the exhaust fan 25 drives the exhaust gas through the intake grille 22 and intake port 21 into the interior of the first fixed box 23. Inside the first fixed box 23, the exhaust gas passes through the condenser 26, where the condenser 26 condenses the moisture inside, causing it to fall to the first sliding frame 28. After being filtered by the three layers of the first sliding frame 28—the pre-filter 29, the dust filter 210, and the activated carbon filter 211—the exhaust gas is discharged through the drain pipe 212. After dehumidification, the gas in the main body 26 is transported to the second fixed box 31 through the conveying pipe 24. When the gas passes through the conveying pipe 24, the first motor 310 drives the rotating disk 311 to rotate. When the rotating disk 311 rotates, it cooperates with the guide block 314 through the fixed rod 312, which drives the sliding rack 313 to slide back and forth. When the sliding rack 313 slides, it cooperates with the rotating gear 315, which drives the grille blade 316 to rotate, thereby adjusting the angle and direction of the exhaust gas entry to prevent it from concentrating inside the second fixed box 31. After being placed inside the fixed box 31, the particulate matter inside is adsorbed and purified by the activated carbon adsorbent placement plate 33 before being discharged. When it is necessary to replace or clean the activated carbon adsorbent placement plate 33, the locking block 38 is slid to release it from the locking with the rotating plate 35. Then, the rotating plate 35 is rotated to open it, thereby releasing the restriction on the activated carbon adsorbent placement plate 33, which can then be removed. The replacement activated carbon adsorbent placement plate 33 is then placed back inside the second limiting block 32, and the rotating plate 35 is rotated, passing through the sealing gasket. 36 is released from the gap between the activated carbon adsorbent placement plate 33 and the second fixed box 31 to seal it and prevent subsequent exhaust gas from flowing out through the gap. After rotating the rotating plate 35, the locking block 38 is released, and the first spring 39 provides a pushing force to the locking block 38. When the filter plate needs to be cleaned later, the corresponding first sliding frame 28 is pulled out and removed along with the filter plate to be replaced. After removal, the rotating rod 213 is rotated, and the sliding plate 214 is moved away from the filter plate by the rotating rod 213, and then the filter plate is removed for replacement.
[0029] Through the above steps, after the exhaust gas is dehumidified by the condenser body 26, it is filtered by the pre-filter plate body 29, the dust filter plate body 210 and the activated carbon filter plate 211 before being discharged. This solves the problem that when the dehumidification mechanism pre-treats the exhaust gas, some particulate matter will mix with the condensate water, and the particulate matter will be discharged with the condensate water, causing environmental pollution.
