Description
Technical Field
[0001] This utility model relates to the technical field of chemical waste gas treatment equipment, specifically to a carbon fiber tail gas adsorption device. Background Technology
[0002] In chemical production processes, especially in the synthesis of organic compounds such as o-phenylenediamine, exhaust gases often contain large amounts of harmful substances, such as unreacted raw materials, byproducts, and solvent vapors. Direct emissions of these substances not only cause serious environmental pollution but may also affect production efficiency and product quality. Therefore, effective treatment of waste gases generated during chemical production is necessary.
[0003] Traditional waste gas treatment methods often employ fixed layers of carbon fiber for impurity adsorption. Carbon fiber, as a unique adsorption material, exhibits excellent adsorption performance due to its abundant porous structure and extremely high specific surface area, making it widely used in waste gas treatment.
[0004] However, as the waste gas treatment process progresses, the waste gas tends to concentrate in certain localized areas when passing through the carbon fiber layer, causing these areas to quickly become saturated and their adsorption capacity to drop sharply. Meanwhile, other areas of the carbon fiber layer fail to function effectively due to uneven waste gas distribution, resulting in a significant reduction in overall adsorption efficiency. This not only wastes the adsorption capacity of the carbon fiber but also increases the cost and time required for waste gas treatment. Utility Model Content
[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a carbon fiber exhaust gas adsorption device, which solves the problem that when exhaust gas passes through the carbon fiber layer, it often concentrates in certain local areas, causing these areas to quickly become saturated and the adsorption capacity to drop sharply.
[0006] To achieve the above objectives, according to an embodiment of the first aspect of this utility model, a carbon fiber exhaust gas adsorption device is provided, comprising an adsorption box, a frame, a carbon fiber plate, a movable slide plate, an air inlet hood, and an air inlet pipe. The adsorption box has an air inlet and an exhaust outlet at its two ends, respectively. A slot is provided on the side of the adsorption box, located between the air inlet and the exhaust outlet. The carbon fiber plate is fixedly connected to the frame. A movable groove is provided on the inner side of the adsorption box, located between the slot and the air inlet. The movable slide plate is slidably disposed within the movable groove. One end of the air inlet hood is fixedly connected to the movable slide plate, and the other end of the air inlet hood is connected to one end of the air inlet pipe. The other end of the air inlet pipe is connected to the air inlet.
[0007] According to one embodiment of the present invention, a locking component for limiting the sliding of the insertion frame is fixedly provided on the side of the adsorption box, and the locking component is located at the slot opening of the slot.
[0008] According to one embodiment of the present invention, the locking assembly includes a fixed sleeve and a movable baffle. The fixed sleeve is fixedly disposed at the slot opening of the slot, and the movable baffle is slidably connected to the fixed sleeve.
[0009] According to one embodiment of the present invention, the locking assembly further includes a spring, one end of which is connected to a fixed sleeve, and the other end of which is connected to a movable baffle.
[0010] According to one embodiment of the present invention, one end of the movable baffle is provided with an inclined guide surface.
[0011] According to one embodiment of the present invention, a lead screw is rotatably disposed in the movable slide groove, and the movable slide plate is provided with a mating hole that is threadedly connected to the lead screw.

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] like Figures 1 to 5 As shown, a carbon fiber exhaust gas adsorption device includes an adsorption box 1, a frame 2, a carbon fiber plate 3, a movable slide plate 4, an air inlet hood 5, and an air inlet pipe 6. The adsorption box 1 has an air inlet 7 and an exhaust outlet 8 at its two ends, respectively. A slot 9 is provided on the side of the adsorption box 1, located between the air inlet 7 and the exhaust outlet 8. The carbon fiber plate 3 is fixedly connected to the frame 2. A movable slide groove 10 is provided on the inner side of the adsorption box 1, located between the slot 9 and the air inlet 7. The movable slide plate 4 is slidably disposed within the movable slide groove 10. One end of the air inlet hood 5 is fixedly connected to the movable slide plate 4, and the other end of the air inlet hood 5 is connected to one end of the air inlet pipe 6. The other end of the air inlet pipe 6 is connected to the air inlet 7.
[0029] Specifically, the exhaust gas first enters the intake pipe 6 through the intake port 7. The intake pipe 6 is connected to the intake hood 5, one end of which is fixedly connected to the movable slide plate 4. The movable slide plate 4 can slide within the movable groove 10 inside the adsorption box 1, allowing the position of the intake hood 5 to be adjusted within a certain range. When the exhaust gas enters the adsorption box 1 through the intake hood 5, due to the guiding and distributing effect of the intake hood 5, the exhaust gas can be more evenly distributed on the carbon fiber plate 3.
[0030] The carbon fiber plate 3 is fixedly connected to the adsorption box 1 via the insert frame 2. The slot 9 design allows for easy installation and replacement of the carbon fiber plate 3. When the exhaust gas is evenly distributed on the carbon fiber plate 3, the porous structure and high specific surface area of the carbon fiber can fully exert its adsorption performance, effectively removing harmful substances from the exhaust gas.
[0031] The treated exhaust gas is then discharged from the adsorption box 1 through the exhaust port 8, completing the entire exhaust gas treatment process. Due to the configuration of the air intake hood 5 and the movable slide plate 4, the exhaust gas can be evenly distributed on the carbon fiber plate 3, avoiding the problem of exhaust gas concentrating in certain local areas and causing a rapid decrease in adsorption capacity in traditional methods.
[0032] The intake hood 5 and the movable slide plate 4 ensure that exhaust gas is evenly distributed on the carbon fiber plate 3, fully utilizing the adsorption capacity of the carbon fiber and improving overall adsorption efficiency. Because of the uniform exhaust gas distribution, all areas of the carbon fiber plate 3 are fully utilized, avoiding the problem of rapid saturation in localized areas, thus extending the service life of the carbon fiber plate 3. The improved adsorption efficiency and extended service life of the carbon fiber plate 3 reduce the frequency of replacing the carbon fiber plate 3 and the cost of exhaust gas treatment.
[0033] refer to Figure 1 As shown, in some specific embodiments, a locking component 11 for limiting the sliding of the insertion frame 2 is fixedly provided on the side of the adsorption box 1, and the locking component 11 is located at the slot opening of the slot 9. The main purpose of the locking component 11 is to fix the insertion frame 2 after the carbon fiber plate 3 is installed into the slot 9 through the insertion frame 2, so as to prevent it from sliding or falling off during operation, thereby ensuring the continuity and stability of exhaust gas treatment.
[0034] refer to Figure 2 As shown, in some specific embodiments, the locking component 11 includes a fixed sleeve 12 and a movable baffle 13. The fixed sleeve 12 is fixedly disposed at the slot of the slot 9, and the movable baffle 13 is slidably connected to the fixed sleeve 12.
[0035] After the carbon fiber plate 3 is installed into the slot 9 through the insert frame 2, the operator can manually push the movable baffle 13 to slide it outward within the fixed sleeve 12 until it tightly contacts and locks the insert frame 2. At this time, the movable baffle 13 serves to fix the insert frame 2 and prevent it from sliding or falling off. Conversely, when it is necessary to replace the carbon fiber plate 3, the operator only needs to push the movable baffle 13 in the opposite direction to slide it inward within the fixed sleeve 12 to unlock the insert frame 2, making it easy to slide the insert frame 2 together with the carbon fiber plate 3 out of the slot 9.
[0036] refer to Figure 5 As shown, in some specific embodiments, the locking assembly 11 further includes a spring 14, one end of which is connected to the fixed sleeve 12, and the other end of which is connected to the movable baffle 13.
[0037] After the carbon fiber plate 3 is successfully installed into the slot 9 through the insert frame 2, the spring 14 pushes the movable baffle 13, causing it to slide outward within the fixed sleeve 12 until it is tightly fitted with the insert frame 2. At this time, the elastic force of the spring 14 provides a continuous and stable thrust to the movable baffle 13, ensuring that the movable baffle 13 can firmly lock the insert frame 2 and prevent any form of slippage or detachment. When it is necessary to replace the carbon fiber plate 3, the operator can manually overcome the elastic force of the spring 14 and push the movable baffle 13 in the opposite direction, causing it to slide inward within the fixed sleeve 12, thereby unlocking the insert frame 2.
[0038] refer to Figure 5 As shown, in some specific embodiments, one end of the movable baffle 13 has an inclined guide surface 15. During the insertion of the insert frame 2 into the slot 9, one end of the insert frame 2 can naturally press and push the guide surface 15 of the movable baffle 13, thereby causing the movable baffle 13 to slide inward within the fixed sleeve 12. The guide surface 15 makes the insertion and locking process of the insert frame 2 smoother and simpler, greatly reducing the difficulty of operation and time cost.
[0039] refer to Figure 4 As shown, in some specific embodiments, a lead screw 16 is rotatably arranged inside the movable slide 10, the movable slide plate 4 has a mating hole that is threadedly connected to the lead screw 16, and a motor 17 is fixedly arranged on the top of the adsorption box 1, the output end of the motor 17 is coaxially fixedly connected to the lead screw 16.
[0040] When the position of the intake hood 5 needs to be adjusted to change the distribution of exhaust gas, simply start the motor 17 and adjust its rotation direction and speed to move the movable slide plate 4 along the lead screw 16 to the desired position. In this way, the intake hood 5 can guide the exhaust gas to be distributed more evenly on the carbon fiber plate 3, thereby improving the adsorption efficiency.
[0041] refer to Figure 4 As shown, in some specific embodiments, the intake pipe 6 is a corrugated hose. Due to its unique structural characteristics—a continuous corrugated shape on the pipe body—the corrugated hose exhibits excellent flexibility and extensibility. This characteristic allows the corrugated hose to adapt to various complex installation environments and space constraints, ensuring that exhaust gas can be smoothly delivered from the intake port 7 to the intake hood 5.
[0042] refer to Figure 2 As shown, in some specific embodiments, a handle 18 is fixedly provided on the side of the insertion frame 2. The handle 18 is typically made of a sturdy and easy-to-grip material, such as metal or hard plastic, to ensure stability and safety during operation. When the carbon fiber plate 3 needs to be replaced, the operator can simply grasp the handle 18 and easily pull the insertion frame 2 out of the slot 9 of the adsorption box 1. Similarly, when installing a new carbon fiber plate 3, the operator can also smoothly insert the insertion frame 2 into the slot 9 using the handle 18 and ensure it is firmly in place. This greatly simplifies the replacement process of the carbon fiber plate 3 and improves work efficiency.
[0043] refer to Figure 2 As shown, in some specific embodiments, a filter screen 19 is fixedly installed at the slot of the exhaust port 8. The main function of the filter screen 19 is to act as a barrier to effectively block foreign objects (such as dust, particulate matter, etc.) from the external environment from entering the adsorption box 1. The filter screen 19 is usually made of a fine mesh material, which is small enough to block most foreign objects from passing through while ensuring that the exhaust gas is discharged smoothly.
[0044] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be explained in conjunction with specific application scenarios:
[0045] The exhaust gas first enters the intake pipe 6 through the intake port 7. The intake pipe 6 adopts a corrugated hose structure, which has good flexibility and extensibility, and can adapt to complex installation environments and space constraints. The corrugated hose is connected to the intake hood 5, one end of which is fixedly connected to the movable slide plate 4. The movable slide plate 4 can slide within the movable groove 10 inside the adsorption box 1, and is precisely controlled by the lead screw 16 driven by the motor 17.
[0046] When the exhaust gas enters the adsorption box 1 through the intake hood 5, the guiding and distributing effect of the intake hood 5 allows the exhaust gas to be more evenly distributed on the carbon fiber plate 3. By adjusting the position of the movable slide plate 4, the position of the intake hood 5 can be changed, thereby further optimizing the distribution of exhaust gas. This adjustment process is achieved by the motor 17 driving the lead screw 16, which is simple and precise to operate.
[0047] The carbon fiber plate 3 is fixedly connected to the adsorption box 1 via the insert frame 2, and the slot 9 allows for easy installation and replacement of the carbon fiber plate 3. The porous structure and high specific surface area of the carbon fiber plate 3 can fully utilize its adsorption performance to effectively remove harmful substances from the exhaust gas. The locking component 11 ensures that the insert frame 2 will not slide or fall off after installation, guaranteeing the continuity and stability of exhaust gas treatment.
[0048] The treated exhaust gas is discharged from the adsorption box 1 through the exhaust port 8. A filter screen 19 is installed at the exhaust port 8 to effectively block foreign objects from the external environment from entering the adsorption box 1. The filter screen 19 is made of fine mesh material, which can block most foreign objects from passing through while ensuring smooth exhaust gas discharge.
[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
