Abstract
Description
Technical Field
[0001] This utility model belongs to the field of waste gas treatment technology, and in particular relates to a plasma waste gas treatment device for preventing carbon buildup. Background Technology
[0002] Plasma exhaust gas purifiers are devices that utilize low-temperature plasma technology to treat air pollutants. They are primarily used in industrial waste gas treatment in sectors such as petroleum, pharmaceuticals, and paint, but also have applications in homes, hospitals, and offices. The device consists of a microwave excitation zone, a low-temperature plasma excitation zone, and an electrode zone. It ionizes the air using a high-voltage electric field to generate high-energy particles that decompose volatile organic compounds, PM2.5, and formaldehyde, producing harmless substances such as carbon dioxide and water. Employing an electrocatalytic oxidation process combined with an adsorption-decomposition-carbonization flow, it boasts high treatment efficiency, requires no filter maintenance, and offers advantages such as low energy consumption and quiet operation. Core components include a microwave unit, electrodeless lamp assembly, and a high-voltage electric field. The device's performance can be assessed through the coverage of the discharge area and its power parameters.
[0003] Patent document CN222518094U discloses a low-temperature plasma waste gas treatment device, including a treatment device and an inlet pipe and an outlet pipe connected at both ends of the treatment device. A low-temperature plasma device is fixedly installed inside the treatment device. Two strip-shaped holes are opened on the top of the treatment device, and dust removal filters are slidably inserted into each of the two strip-shaped holes. Baffles are fixed at both ends of the dust removal filters. A vertical plate is fixedly installed on the top of the treatment device, and a switching application mechanism for switching the two dust removal filters is provided between the vertical plate and the two dust removal filters.
[0004] The application document states that by switching between two filters, the dust accumulated on the surface of the filters after long-term use can be effectively cleaned, ensuring stable exhaust gas treatment. However, during the process of exhaust gas entering the treatment device through the intake pipe, incompletely burned carbon substances in the exhaust gas will adhere to the wall of the intake pipe, which can easily cause blockage over time and affect the entry of exhaust gas. Therefore, this aspect needs to be improved. Utility Model Content
[0005] The purpose of this invention is to provide a plasma waste gas treatment device that prevents carbon buildup, which solves the existing problems through the design of an anti-carbon buildup and clogging mechanism.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a plasma exhaust gas treatment device for preventing carbon buildup, comprising a body, an exhaust pipe that is fixedly connected to the top of the body, a first opening and a second opening that are fixedly connected to the side of the body, a filter screen, a plasma electrode rod and a shaking mechanism inside the body, and an anti-carbon buildup and clogging mechanism on the side of the body away from the first opening; the anti-carbon buildup and clogging mechanism includes an intake pipe, a support plate that is fixedly connected to the inside of the intake pipe, a slide rod that is slidably connected to the side of the support plate, a closing plate that is fixedly connected to the side of the slide rod, a closing ring that is fixedly connected to the surface of the slide rod, a telescopic spring that is provided on the side of the support plate, a connecting groove that is formed in the inner wall of the intake pipe, a connecting hole that is formed inside the intake pipe, an outlet that is formed on the side of the connecting groove, a short rod that is fixedly connected to the side of the connecting groove, a closing ring and a limiting block that are fixedly connected to both ends of the short rod, and a compression spring that is sleeved on the surface of the short rod.
[0008] Furthermore, the end of the telescopic spring away from the support plate is fixedly connected to the closing plate. In the initial state, the closing plate is in contact with the air intake pipe. When no exhaust gas enters the machine body through the air intake pipe, the air intake pipe will be in a closed state.
[0009] Furthermore, in its initial state, the closed ring is close to the connecting hole, which is connected to the connecting groove. When the closed ring moves to the right, it will close the connecting hole.
[0010] Furthermore, in the initial state, the closed ring is in contact with the outlet, and the two ends of the compression spring are in contact with the limiting block and the connecting groove, respectively. When the closed ring and the short rod move to the right, the compression spring will be compressed.
[0011] Furthermore, the elastic potential energy of the extension spring is less than that of the compression spring. This design ensures the correct operation of the equipment.
[0012] Furthermore, the shaking mechanism includes a pressure chamber, which is fixedly connected inside the machine body. One end of the pressure chamber is provided with an air bladder, and the other end of the pressure chamber is slidably connected to a piston rod.
[0013] Furthermore, the airbag is initially in an inflated state, and when the airbag is squeezed, the air pressure inside it enters the air chamber and pushes the piston rod upward.
[0014] Furthermore, the end of the piston rod away from the pressure chamber is close to the bottom of the filter screen. The purpose of this design is to ensure that the airflow can be better guided when passing through the filter screen.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model has a carbon buildup and blockage prevention mechanism. When unburned carbon in the exhaust gas adheres to the wall of the intake pipe and forms a blockage, the short rod, sealing ring and other components will work together to open the connection hole and opening, so that the exhaust gas can enter through the connection groove that is not covered by carbon, thereby preventing carbon buildup from affecting the entry of exhaust gas.
[0017] 2. This utility model, by setting a shaking mechanism, achieves the following: during the process of opening the connection hole and opening with the cooperation of components such as the short rod and the closed ring, the piston rod moves upward and hits the filter screen with the cooperation of components such as the air bag and the air pressure chamber. At this time, the filter screen shakes and shakes off the carbon deposits on the surface, preventing the filter screen from being blocked by carbon deposits.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[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] Please see Figures 1-5 As shown, this utility model is a plasma exhaust gas treatment device for preventing carbon buildup, including a body 1. An exhaust pipe 3 is connected through and fixedly to the top of the body 1. A first opening 4 and a second opening 5 are connected through and fixedly to the side of the body 1. A filter screen 6, a plasma electrode rod 7, and a shaking mechanism 8 are arranged inside the body 1. An anti-carbon buildup and clogging mechanism 2 is arranged on the side of the body 1 away from the first opening 4. The anti-carbon buildup and clogging mechanism 2 includes an intake pipe 21, a support plate 22 is fixedly connected inside the intake pipe 21, and a sliding connection is made to the side of the support plate 22. A sliding rod 23 has a closing plate 24 fixedly connected to its side and a closing ring 25 fixedly connected to its surface. A telescopic spring 26 is provided on the side of the support plate 22. A connecting groove 27 is provided on the inner wall of the air intake pipe 21, and a connecting hole 28 is provided inside the air intake pipe 21. An outlet 29 is provided on the side of the connecting groove 27. A short rod 210 is fixedly connected through and to the side of the connecting groove 27. A closing ring 211 and a limiting block 212 are fixedly connected to both ends of the short rod 210, respectively. A compression spring 213 is sleeved on the surface of the short rod 210.
[0029] As shown in the figure, the end of the telescopic spring 26 away from the support plate 22 is fixedly connected to the closing plate 24. In the initial state, the closing plate 24 is in contact with the air intake pipe 21. When no exhaust gas enters the machine body 1 through the air intake pipe 21, the air intake pipe 21 will be in a closed state.
[0030] As shown in the figure, the closed ring 25 is initially close to the connecting hole 28, and the connecting hole 28 is connected to the connecting groove 27. When the closed ring 25 moves to the right, it will close the connecting hole 28.
[0031] As shown in the figure, the closed ring 211 initially abuts against the outlet 29, and the two ends of the compression spring 213 abut against the limit block 212 and the connecting groove 27 respectively. When the closed ring 211 and the short rod 210 move to the right, the compression spring 213 will be compressed.
[0032] As shown in the figure, the elastic potential energy of the extension spring 26 is less than that of the compression spring 213. This design ensures the correct operation of the equipment.
[0033] As shown in the figure, the shaking mechanism 8 includes a pressure chamber 81, which is fixedly connected inside the body 1. One end of the pressure chamber 81 is provided with an air bag 82, and the other end of the pressure chamber 81 is slidably connected to a piston rod 83.
[0034] As shown in the figure, the airbag 82 is initially in an inflated state. When the airbag 82 is squeezed, the air pressure inside it will enter the air pressure chamber 81 and push the piston rod 83 to move upward.
[0035] As shown in the figure, the end of the piston rod 83 away from the air pressure chamber 81 is close to the bottom of the filter screen 6. The purpose of this design is to ensure that the airflow can be better guided when passing through the filter screen 6.
[0036] One specific application of this embodiment is as follows: The intake pipe 21 is connected to the exhaust port. Exhaust gas enters the intake pipe 21, and the air pressure pushes the closing plate 24 to the right, opening the intake pipe 21. The extension spring 26 is stretched, and the exhaust gas enters the machine body 1 through the intake pipe 21. The filter 6 performs initial filtration of the exhaust gas, removing large particulate impurities, while the plasma electrode rod 7 adsorbs other harmful substances in the exhaust gas. Finally, the purified exhaust gas is discharged through the exhaust pipe 3. The filter 6 or plasma electrode rod 7 can be inspected by opening the first opening 4 or the second opening 5. The movement of the closing plate 24 to the right will cause the sliding rod 23 and the closing ring 25 to move to the right. When the closing ring 25 moves to the right, it will seal the connecting hole 28, thus preventing exhaust gas from entering the connecting groove 27 under normal conditions. However, if the exhaust gas is not completely burned... When carbon deposits adhere to the wall of the intake pipe 21 and cause blockage, the telescopic spring 26 rebounds, causing the closing plate 24 to move to the left to return to its original position. At this time, the sliding rod 23 and the closing ring 25 move to the left to return to their original position, and the connecting hole 28 is opened. Exhaust gas enters the connecting groove 27 through the connecting hole 28. The air pressure pushes the closing ring 211 to move to the right to open the outlet 29. At this time, exhaust gas can enter through the connecting groove 27, which is not covered by carbon deposits, thus preventing carbon deposits from affecting the entry of exhaust gas. When the closing ring 211 moves to the right, it will squeeze the air bag 82. When the air bag 82 is squeezed, the air pressure inside it will enter the air pressure chamber 81 and push the piston rod 83 to move upward. The upward movement of the piston rod 83 will hit the filter screen 6, causing the filter screen 6 to shake and shake off the carbon deposits on the surface, preventing the filter screen 6 from being blocked by carbon deposits. This helps to improve the overall device's ability to prevent carbon deposits.
