Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a low-temperature plasma synergistic catalytic purification device for industrial waste gas. Background Technology

[0002] In recent years, the rapid development of modern industry has led to a significant increase in toxic and harmful waste gases, resulting in a sharp rise in the amount of volatile organic compounds (VOCs). VOCs have become one of the major gaseous pollutants plaguing countries worldwide. As people's demands for living environment and quality of life increase, emission standards for VOCs will become increasingly stringent.

[0003] In the prior art, such as the patent application CN211098411U entitled "A Plasma Synergistic Photocatalytic Device for Treating Waste Gas," a purification chamber and three sealing plates are included. The top and bottom inner walls of the purification chamber are symmetrically provided with three equally spaced first grooves, and the inner walls of each of the six first grooves are fixedly fitted with sliding guide rails. Sliding blocks are slidably connected to the outer walls of the sliding guide rails. The plasma synergistic photocatalytic device for treating waste gas proposed in this utility model, by setting up a dust filter plate, a plasma synergistic catalytic discharge device, and a plasma photocatalyst reactor, can first perform preliminary dust filtration on the waste gas, and then use the low-temperature plasma synergistic catalytic effect to decompose the organic waste gas into harmless small molecules. The light emitted by the plasma discharge serves as the light source for photocatalysis, working in conjunction with the plasma photocatalyst reactor to catalytically decompose harmful particles, achieving a very effective waste gas purification effect.

[0004] Existing industrial waste gas low-temperature plasma synergistic catalytic purification devices do not have a clamping and fixing structure for the plasma synergistic catalytic discharge device and the plasma photocatalyst reactor during use, which makes them prone to shaking and causes inconvenience. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing technologies lack a clamping and fixing structure for plasma synergistic catalytic discharge devices and plasma photocatalyst reactors, which easily cause shaking during use and thus inconvenience. Therefore, this invention proposes a low-temperature plasma synergistic catalytic purification device for industrial waste gas.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a low-temperature plasma synergistic catalytic purification device for industrial waste gas, comprising a catalytic purification component, a pressing component at one end of the catalytic purification component, a filter component on the catalytic purification component, the catalytic purification component including a purification chamber and an air inlet pipe, a plasma synergistic catalytic discharge device and a plasma photocatalyst reactor disposed inside the purification chamber, pressure plates disposed on the sides of both the plasma synergistic catalytic discharge device and the plasma photocatalyst reactor, the pressing component including a fixing frame, a limiting pressure plate movably installed inside the fixing frame, a sealing gasket disposed on the side of the purification chamber, and multiple limiting plates disposed inside the purification chamber.

[0007] Preferably, the filter assembly includes a filter cover, which is sleeved on the outside of the air intake pipe, and the outer side of the filter cover is threadedly connected to a threaded sleeve.

[0008] Preferably, a blocking ring is installed on the outer side of the filter screen cover, and the blocking ring is connected to the side of the threaded sleeve.

[0009] Preferably, a limit ring is installed on the outer side of the air intake pipe.

[0010] Preferably, a fan is installed on the side of the purification chamber, and an air outlet frame is installed on the outside of the fan.

[0011] Preferably, a handle is installed on the side of the pressure plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, pulling the handle facilitates the pulling of the plasma synergistic catalytic discharge device and the plasma photocatalyst reactor. A sealing gasket is provided on the side of the purification box to provide a sealing effect. The movable limiting plate moves inside the fixed frame, causing the limiting plate to limit the plasma synergistic catalytic discharge device and the plasma photocatalyst reactor, which helps to press and fix the plasma synergistic catalytic discharge device and the plasma photocatalyst reactor, ensuring the stability of the plasma synergistic catalytic discharge device and the plasma photocatalyst reactor, ensuring their normal operation, avoiding inconvenience caused by shaking, and facilitating maintenance and repair, thereby improving the convenience of operation.

[0014] 2. In this utility model, by sleeved the filter screen cover on the outside of the air inlet pipe and threadedly connected to the outside of the filter screen cover with a threaded sleeve, it is beneficial to limit the position of the filter screen cover, which facilitates the installation, removal and replacement of the filter screen cover. The blocking ring helps to limit the installation of the threaded sleeve, and the limiting ring helps to limit the position of the threaded sleeve. The filter screen cover is beneficial to filtering impurities and particulate matter in industrial waste gas. At the same time, the filter screen cover is set on the air inlet pipe to prevent particulate matter from entering the purification chamber, ensuring the stable operation of the equipment inside the purification chamber, and facilitating the cleaning of impurities and particulate matter.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: a low-temperature plasma synergistic catalytic purification device for industrial waste gas, including a catalytic purification component 1, a pressing component 2 at one end of the catalytic purification component 1, a filter component 3 on the catalytic purification component 1, the catalytic purification component 1 including a purification chamber 101 and an air inlet pipe 103, a plasma synergistic catalytic discharge device 106 and a plasma photocatalyst reactor 107 are arranged inside the purification chamber 101, pressure plates 108 are arranged on the sides of both the plasma synergistic catalytic discharge device 106 and the plasma photocatalyst reactor 107, the pressing component 2 includes a fixing frame 201, a limiting pressure plate 202 is movably installed inside the fixing frame 201, a sealing gasket 203 is arranged on the side of the purification chamber 101, a plurality of limiting plates 204 are arranged inside the purification chamber 101, and a handle 109 is installed on the side of the pressure plate 108.

[0023] In this embodiment, by placing the plasma synergistic catalytic discharge device 106 and the plasma photocatalyst reactor 107 inside the purification chamber 101, the organic waste gas is decomposed using the low-temperature plasma synergistic catalysis to generate harmless small molecules. The light emitted by the plasma synergistic catalytic discharge device 106 serves as the light source for photocatalysis, working in conjunction with the plasma photocatalyst reactor 107 to catalytically decompose harmful particles, achieving a very effective waste gas purification effect. Pulling the handle 109 facilitates the pulling of the plasma synergistic catalytic discharge device 106 and the plasma photocatalyst reactor 107. The limiting plate 204 facilitates the movement of the plasma synergistic catalytic discharge device 106 and the plasma photocatalyst reactor 107. The catalyst reactor 107 is provided with left and right limits. A sealing gasket 203 is provided on the side of the purification box 101. The sealing gasket 203 helps to provide a sealing effect. The movable limiting pressure plate 202 moves inside the fixed frame 201, causing the limiting pressure plate 202 to limit the plasma co-catalytic discharge device 106 and the plasma photocatalyst reactor 107. This helps to press and fix the plasma co-catalytic discharge device 106 and the plasma photocatalyst reactor 107, ensuring their stability and normal operation, avoiding inconvenience caused by shaking, and facilitating maintenance and repair, thereby improving the ease of operation.

[0024] Example 2: As Figures 1-4As shown, the filter assembly 3 includes a filter cover 301, which is sleeved on the outside of the air intake pipe 103.

A fan 104 is installed on the side of the purification box 101, and an air outlet frame 105 is installed on the outside of the fan 104.

[0025] In this embodiment, by sleeved the filter cover 301 on the outside of the air inlet pipe 103 and threadedly connected to the outside of the filter cover 301 with a threaded sleeve 303, it is beneficial to limit the position of the filter cover 301 and facilitate the installation, removal and replacement of the filter cover 301. The blocking ring 302 helps to limit the installation of the threaded sleeve 303, and the limiting ring 304 helps to limit the position of the threaded sleeve 303. The filter cover 301 is beneficial to filtering impurities and particulate matter in industrial waste gas. At the same time, the filter cover 301 is set on the air inlet pipe 103 to prevent particulate matter from entering the purification chamber 101, ensuring the stable operation of the equipment inside the purification chamber 101, and facilitating the cleaning of impurities and particulate matter. The fan 104 helps to increase the airflow velocity, thereby improving the efficiency of waste gas purification treatment.

[0026] The working principle of this embodiment is as follows: In use, the filter screen 301 facilitates the filtration of impurities and particulate matter in industrial waste gas. The plasma-assisted catalytic discharge device 106 and the plasma photocatalyst reactor 107 are placed inside the purification chamber 101. The low-temperature plasma assisted catalytic action decomposes the organic waste gas, generating harmless small molecules. The light emitted by the plasma-assisted catalytic discharge device 106 serves as the light source for photocatalysis, working in conjunction with the plasma photocatalyst reactor 107 to catalytically decompose harmful particles, achieving a highly effective waste gas purification effect. The filter screen 301 is fitted onto the outside of the inlet pipe 103, and a threaded sleeve 303 is threaded onto the outside of the filter screen 301, facilitating the cleaning of the filter screen 301. The limit position facilitates the installation, removal, and replacement of the filter cover 301. Pulling the handle 109 facilitates the pulling of the plasma synergistic catalytic discharge device 106 and the plasma photocatalyst reactor 107. The side of the purification box 101 is provided with a sealing gasket 203, which helps to provide a sealing effect. The movable limit plate 202 moves inside the fixed frame 201, causing the limit plate 202 to limit the plasma synergistic catalytic discharge device 106 and the plasma photocatalyst reactor 107, which helps to press and fix the plasma synergistic catalytic discharge device 106 and the plasma photocatalyst reactor 107, ensuring the stability of the plasma synergistic catalytic discharge device 106 and the plasma photocatalyst reactor 107.
