Description

Technical Field

[0001] This utility model belongs to the field of VOC exhaust gas treatment boxes, and more specifically, it relates to a VOC exhaust gas treatment device. Background Technology

[0002] In many fields such as industrial production, chemical manufacturing, and coating operations, the emission of volatile organic compounds (VOCs) is becoming increasingly prominent. VOCs not only cause serious pollution to the atmospheric environment and trigger environmental problems such as photochemical smog, but also pose a great threat to human health, such as irritating the respiratory tract and affecting the nervous system.

[0003] In existing VOC waste gas treatment devices, activated carbon filters are one of the most commonly used treatment units. Activated carbon, with its large specific surface area and abundant pore structure, can efficiently adsorb VOC components in waste gas, thereby achieving the purpose of purifying the waste gas. However, this traditional activated carbon filter has many drawbacks in practical applications.

[0004] Activated carbon gradually reaches saturation after adsorbing a certain amount of VOCs and loses its adsorption capacity. At this point, the activated carbon needs to be replaced. However, the process of replacing activated carbon usually requires machine shutdown, which not only leads to production line interruption and affects the company's production efficiency and economic benefits, but also because most activated carbon filter boxes use a drawer-type structure to remove and replace the activated carbon. When the drawer is opened to remove the activated carbon, new external ventilation slots are easily created, which can easily lead to a large amount of untreated VOC waste gas being discharged from inside. This untreated waste gas is directly emitted into the atmosphere, which not only aggravates environmental pollution, but also poses a direct threat to the health of on-site operators.

[0005] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a VOC exhaust gas treatment device, in order to achieve a more practical value. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a VOC waste gas treatment device to solve the problem that waste gas leakage is easily caused by stopping the waste gas treatment box to replace activated carbon in the prior art.

[0007] The purpose and effectiveness of this VOC waste gas treatment device are achieved by the following specific technical means: A VOC exhaust gas treatment device includes an exhaust gas treatment box. One end of the exhaust gas treatment box has an air inlet, and the other end has an air outlet. An outer plate is fixedly installed on one side of the exhaust gas treatment box, and multiple sets of sealing grooves are formed on the outer plate. Multiple sets of fixing plates are fixedly installed inside the exhaust gas treatment box, and each of the fixing plates has a ventilation groove at its bottom. Multiple sets of drawers are provided on the exhaust gas treatment box, and a sealing plate is fixedly installed on one end of each drawer. A sealing block is fixedly installed on the sealing plate, and the sealing block is covered with rubber. A drawer plate is fixedly installed on the other end of each drawer.

[0008] Furthermore, each of the multiple sets of fixed plates is fixedly installed with two sets of limiting plates, and a drawer is slidably installed between the two sets of limiting plates.

[0009] Furthermore, two sets of support plates are fixedly installed at the bottom of the drawer, and multiple sets of rotating shafts are rotatably installed on the two sets of support plates. Two sets of grooves are provided on the fixed plate, and the support plates are movably engaged with the inner walls of the two sets of grooves.

[0010] Furthermore, handles are fixedly installed on the outer surface of each drawer, and the drawer is fixedly connected to the outer surface of the outer plate by multiple sets of bolts.

[0011] Furthermore, each of the multiple sets of drawers contains a storage box, which has multiple sets of second ventilation holes. The inner walls of the fixing plate are provided with grooves on both sides. The bottom of each drawer has multiple sets of first ventilation holes, and the multiple sets of first ventilation holes correspond one-to-one with the multiple sets of second ventilation holes.

[0012] Furthermore, multiple sets of support frames are fixedly installed on the outer surface of the outer panel.

[0013] Furthermore, a first guide plate and a second guide plate are fixedly installed inside the exhaust gas treatment box.

[0014] Compared with the prior art, the present invention has the following beneficial effects: By interlocking the sealing block on the sealing plate with the sealing groove on the outer plate, and by using rubber wrapped on the sealing block with good elasticity and sealing properties, the gap between the drawer and the outer plate can be effectively sealed to prevent exhaust gas leakage, which greatly reduces the risk of exhaust gas leakage causing environmental pollution.

[0026] As attached Figure 1 To be continued Figure 7 As shown: This utility model provides a VOC exhaust gas treatment device, including an exhaust gas treatment box 1. The exhaust gas treatment box 1 has an air inlet 2 at one end and an air outlet 3 at the other end. An outer plate 8 is fixedly installed on one side of the exhaust gas treatment box 1, and multiple sets of sealing grooves 81 are opened on the outer plate 8. Multiple sets of fixing plates 7 are fixedly installed inside the exhaust gas treatment box 1, and ventilation square grooves 72 are opened at the bottom of each set of fixing plates 7. Multiple sets of drawers 52 are provided on the exhaust gas treatment box 1. A sealing plate 56 is fixedly installed on one end of each set of drawers 52, and a sealing block 57 is fixedly installed on the sealing plate 56. The sealing block 57 is wrapped with rubber. A drawer plate 5 is fixedly installed on the other end of each set of drawers 52.

[0027] Each of the multiple fixed plates 7 has two sets of limiting plates 71 fixedly installed on it. A drawer box 52 is slidably installed between the two sets of limiting plates 71. The two sets of limiting plates 71 play a guiding and limiting role, ensuring that the drawer box 52 moves in the correct direction during the process of being pulled out and pushed back.

[0028] The bottom of the drawer 52 is fixedly equipped with two sets of support plates 54, and multiple sets of rotating shafts 55 are rotatably installed on the two sets of support plates 54. The fixed plate 7 has two sets of grooves 73, and the support plates 54 are movably engaged with the inner walls of the two sets of grooves 73. The engagement of the support plates 54 and the grooves 73 provides stable support for the drawer 52, allowing it to be placed stably in the exhaust gas treatment box 1. At the same time, the rotating shafts 55 on the support plates 54 play a rolling friction role during the process of the drawer 52 being pulled out and pushed back, reducing the friction force during sliding.

[0029] Handles 51 are fixedly installed on the outer surface of the drawer plate 5, and the drawer plate 5 is fixedly connected to the outer surface of the outer plate 8 by multiple sets of bolts 6. The handles 51 provide the operator with a point of leverage, making it convenient for them to pull the drawer plate 5, thereby driving the drawer box 52 to be pulled out or pushed back. The bolts 6 are used to firmly fix the drawer plate 5 to the outer plate 8, ensuring the stability and sealing of the drawer box 52 under normal working conditions.

[0030] Each of the multiple drawer boxes 52 contains a storage box 76. The storage box 76 has multiple sets of second ventilation holes 75, and the inner walls of the fixing plate 7 have grooves 74 on both sides. The bottom of the drawer box 52 has multiple sets of first ventilation holes 53, and the multiple sets of first ventilation holes 53 correspond one-to-one with the multiple sets of second ventilation holes 75. The storage box 76 is used to store adsorption materials such as activated carbon to adsorb harmful substances in the waste gas. The one-to-one correspondence between the first ventilation holes 53 and the second ventilation holes 75 allows the waste gas to smoothly enter the storage box 76 from the bottom of the drawer box 52 and fully contact the adsorption material. The grooves 74 make it convenient for operators to remove or put the storage box 76 from the drawer box 52 by holding the grooves 74 when changing the storage box 76.

[0031] Among them, multiple sets of support frames 4 are fixedly installed on the outer surface of the outer panel 8. When the drawer 52 is pulled out, the support frames 4 play a supporting role to prevent the drawer 52 from sagging or deforming due to its own weight or external force.

[0032] The exhaust gas treatment box 1 is equipped with a first guide plate 11 and a second guide plate 12. The first guide plate 11 blocks and guides the incoming exhaust gas, allowing the airflow to be discharged from its middle and enter the subsequent treatment area more evenly. The second guide plate 12 guides the treated exhaust gas to flow towards the outlet 3.

[0033] The specific usage and function of this embodiment are as follows: In this utility model, the air inlet 2 of the exhaust gas treatment box 1 is first connected to the external exhaust gas discharge pipe. When the exhaust gas enters the interior of the exhaust gas treatment box 1 from the air inlet 2, it will first encounter the first guide plate 11 set inside the device. The first guide plate 11 is installed at a specific angle and shape, which plays a role in blocking and guiding the incoming exhaust gas. Due to the obstruction of the first guide plate 11, the exhaust gas cannot diffuse directly laterally, but is guided to be discharged from the middle of the first guide plate 11, so that the exhaust gas can enter the subsequent treatment area more evenly. After being initially guided by the first guide plate 11, the exhaust gas will flow along the airflow direction to the ventilation groove 72 at the bottom of the fixed plate 7. The ventilation groove 72 provides a channel for the exhaust gas to enter the drawer 52, and the exhaust gas flows into the interior of the drawer 52 through the ventilation groove 72.

[0034] The drawer box 52 is the core area for waste gas treatment. Inside it is a storage box 76, which has multiple sets of second vents 75. Simultaneously, the bottom of the drawer box 52 also has multiple sets of first vents 53, with each first vent 53 corresponding to a second vent 75 on the storage box 76. Waste gas enters the storage box 76 through these corresponding vents. Storage box 76 is used to store adsorption materials such as activated carbon. When the exhaust gas enters storage box 76, it will come into full contact with the activated carbon. With its huge specific surface area and rich pore structure, the activated carbon can efficiently adsorb VOC components in the exhaust gas, such as benzene, toluene, xylene and other harmful substances, thereby achieving the purpose of purifying the exhaust gas. After being purified by activated carbon filtration, the exhaust gas completes the purification process in the storage box 76 and flows out from the other side of the storage box 76. It then flows out of the drawer box 52 again through the first vent 53 at the bottom of the drawer box 52, which corresponds to the storage box 76. At this time, the second guide plate 12 inside the device comes into play. The second guide plate 12 guides the purified exhaust gas a second time, directing the exhaust gas towards the outlet 3. When activated carbon adsorption becomes saturated and needs replacement, there is no need to stop the machine. The operator uses tools to unlock multiple bolts 6, releasing the fixed connection between the drawer plate 5 and the outer plate 8. The operator then pulls the drawer plate 5 outward by holding the handle 51 on the outer surface of the drawer plate 5, thereby causing the drawer box 52 to slide out of the waste gas treatment box 1. During the sliding of the drawer box 52, the two sets of limiting plates 71 on the fixing plate 7 act as guides, ensuring that the drawer box 52 slides in the correct direction and preventing the drawer box 52 from deviating during the sliding process. When the drawer box 52 slides to the end, the sealing block 57 on the sealing plate 56 at one end of the drawer box 52 and the sealing groove 81 on the outer plate 8 interlock. The sealing block 57 is wrapped with rubber, which has good elasticity and sealing properties, and can effectively seal the gap between the drawer box 52 and the outer plate 8 to prevent waste gas leakage. At this time, although the drawer box 52 is pulled out, the other parts inside the exhaust gas treatment box 1 can still work normally and the exhaust gas treatment will not be affected by the removal of the drawer box 52. After the drawer box 52 is sealed, the operator can take out the storage box 76 from the drawer box 52 by holding the pull grooves 74 on both sides of the inner wall of the fixing plate 7, and then open the storage box 76 to replace the new adsorption material containing activated carbon.
