Description
Technical Field
[0001] This utility model relates to the field of gas filtration and purification technology, and in particular to a gas filtration and purification device. Background Technology
[0002] A gas filtration and purification device is a functional device specifically designed to remove impurities, pollutants, and harmful components from gas. It works by using physical interception, adsorption, and separation techniques to remove substances from gas that could affect transmission safety, equipment operation, or end-use performance, thus outputting clean gas that meets national or industry standards and ensuring the safety, stability, and environmental friendliness of gas throughout the entire supply chain.
[0003] Gas filtration and purification devices operate through multi-stage interception and precise separation. Gas containing impurities enters the pretreatment chamber, where a guide plate guides the flow to form a spiral flow field. Centrifugal force is used to separate large particles, liquid oil, and water. Impurities are discharged through the drain port, and the gas enters the core filtration unit. The porous structure adsorbs micro-oil mist, which is then adsorbed by activated carbon. The purified gas is then transported after pressure regulation by a pressure stabilizing valve to ensure stable operation. However, existing gas filtration and purification devices have performance limitations and cannot handle all impurities. The types of impurities that the filtration devices can handle are limited, and a single device cannot achieve purification of multiple impurities. Furthermore, the purification range is narrow and easily affected by operating conditions. If multiple impurities are to be processed, impurities may pass through the filter element before being fully filtered, requiring multiple sets of different types of devices to be connected in series. This increases equipment investment and expands the system size. Utility Model Content

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a gas filtration and purification device, comprising a filter tank 1, a purification mechanism 2 fixedly connected to the upper part of the inner wall of the filter tank 1, the purification mechanism 2 being used to filter and purify gas, and a maintenance mechanism 3 fixedly connected to the bottom of the outer wall of the purification mechanism 2, the maintenance mechanism 3 being used for convenient disassembly of the device; the purification mechanism 2 includes a purification tank 201, the purification tank 201 being fixedly connected to the middle of the inner wall of the filter tank 1, an exhaust pipe 202 connected to the top of the outer side of the filter tank 1, a circulation pipe 203 connected to the bottom of the outer wall of the purification tank 201, and a sealing ring fixedly connected to the top of the outer wall of the purification tank 201. 204. A screen 205 is fixedly connected to the middle of the inner side of the purification tank 201. A filter element 206 is fixedly connected to the top of the inner wall of the screen 205. A rotating assembly 207 is fixedly connected to the top of the outer wall of the filter tank 1. The rotating assembly 207 includes an air supply pipe 2071. The air supply pipe 2071 is fixedly connected to the top of the outer wall of the filter tank 1. A motor 2072 is fixedly connected to the middle of the top wall of the air supply pipe 2071. The model of the motor 2072 is Y112M-2. A blade 2073 is fixedly connected to the output end of the motor 2072. A flange 2074 is fixedly connected to one side of the outer wall of the air supply pipe 2071.
[0032] Specifically, the gas to be purified enters the system from the top of the device through the gas delivery pipe 2071 of the rotating component 207. The motor 2072 starts and drives the blades 2073 to rotate, which helps to stabilize the gas delivery and initially sort the airflow, reducing the impact on subsequent purification. The flange 2074 on the outer wall of the gas delivery pipe 2071 ensures the connection is sealed. The gas enters the filter tank 1 and flows to the purification mechanism 2. It first enters the purification tank 201 and is initially intercepted by the screen 205 for larger solid impurities. Then, it is finely filtered by the filter element 206 for fine solid particles and liquid droplets, achieving deep purification. The sealing ring 204 at the top of the purification tank 201 ensures a seal. The gas that is not completely purified flows back through the circulation pipe 203 for secondary filtration. The clean gas that meets the standards is discharged through the exhaust pipe 202 for downstream use. The maintenance mechanism 3 can be easily disassembled, replaced or cleaned during device maintenance to ensure stable operation of the device.
[0033] Reference Figure 1 , Figure 2 and Figure 5 The maintenance mechanism 3 includes a fixing ring 301, which is fixedly connected to the inner middle of the filter tank 1. A fixing bracket 302 is fixedly connected to the top side of the fixing ring 301. A connecting ring 303 is rotatably connected to the top of the outer wall of the fixing bracket 302.

[0034] Specifically, the maintenance mechanism 3 uses the fixing ring 301 as its base carrier, which is securely connected to the middle of the inner side of the filter tank 1, providing an installation reference for the maintenance mechanism 3. The top fixing bracket 302 is rotatably connected to the connecting ring 303. When maintaining the internal screen 205 and filter element 206, the connecting ring 303 is rotated to open the maintenance channel; when closing, the screws 304 around the bottom of the connecting ring 303 are used to tighten it with the corresponding parts to ensure sealing. The bottom connecting assembly 305 on the outer wall of the fixing ring 301 enhances the structural stability and sealing performance. The support ring 3051 is fixed in the middle of the inner side of the fixed ring 301. The bottom support frame 3052 of its inner wall supports and positions the main components of the purification tank 201 to prevent shaking. The second fixed frame 3055 cooperates with the fixed sleeve 3054 to reinforce the connection between the fixed ring 301 and the filter tank 1. The sealing gasket 3053 at the top of the fixed sleeve 3054 enhances the sealing of the connection part to prevent gas leakage. The maintenance mechanism 3 realizes quick disassembly and assembly of the purification components through the rotatable connection structure, multi-point fastening design and sealing components to ensure the stability of the device structure and gas sealing.
[0035] Reference Figure 1 , Figure 2 and Figure 3 Flange 2 4 is fixedly connected to the bottom of filter tank 1. Connecting plate 5 is fixedly connected to the four corners of the outer side of flange 2 4. Fixed rod 7 is rotatably connected to the front and rear sides of the outer wall of connecting ring 303. Fixed plate 6 is fixedly connected to the front and rear sides of the bottom of filter tank 1. Funnel 8 is connected to the bottom of the outer wall of filter tank 1. Bolt 9 is fixedly connected to the bottom of the outer wall of funnel 8. Connecting frame 10 is fixedly connected to the top of filter tank 1. Sleeve 11 is fixedly connected to the left end of the outer wall of exhaust pipe 202.
[0036] Specifically, the flanges 4 around the bottom of the filter tank 1 cooperate with the connecting plate 5 at the outer corner to strengthen the bottom structure of the tank, and the connecting plate 5 facilitates the fixing of the filter tank 1 to downstream equipment or support structures; the fixing plates 6 on the front and rear sides of the bottom of the filter tank 1 further improve the overall stability of the tank body and prevent shaking during operation. Impurities and accumulated liquid generated during purification are collected through the funnel 8 connected to the bottom of the outer wall of the filter tank 1. The bolts 9 at the bottom of the outer wall of the funnel 8 can control the opening and closing of the outlet of the funnel 8, which facilitates the periodic discharge of impurities; clean gas is discharged from the exhaust pipe 202. The sleeve 11 at the left end of the outer wall of the exhaust pipe 202 facilitates the connection with the pipeline of the downstream gas-using equipment, ensuring the sealing and stability of the exhaust connection; in the maintenance mechanism 3, the fixing rod 7 rotatably connected to the front and rear sides of the outer wall of the connecting ring 303 can be flexibly adjusted during disassembly and maintenance, which facilitates the replacement and cleaning of the screen 205 and filter element 206 components, ensuring the long-term stable operation of the device.
[0037] Working principle: The gas to be purified enters the device through the gas delivery pipe 2071 in the rotating assembly 207 from the top of the device. The motor 2072 starts and drives the blades 2073 to rotate. The power generated by the rotation of the blades 2073 can help stabilize the gas delivery and at the same time preliminarily sort the gas flow, reducing the impact of airflow turbulence on subsequent purification stages. The flange 2074 on the outer wall of the gas delivery pipe 2071 ensures the airtightness of the connection between the gas delivery pipe 2071 and the external gas delivery pipeline to prevent gas leakage. The gas enters the filter tank 1 and flows to the purification mechanism 2 fixed in the middle of the inner wall of the filter tank 1. It first enters the purification tank 201. In the purification tank 201, the gas first comes into contact with the screen 205 in the middle of the inner side. The screen 205 preliminarily intercepts and filters the larger solid impurities in the gas. The gas that has been preliminarily filtered by the screen 205 continues to flow upward and reaches the filter at the top of the inner wall of the screen 205. The filter element 206 further filters out fine solid particles, liquid droplets, and other impurities in the gas, achieving deep purification. The sealing ring 204 at the top of the outer wall of the purification tank 201 effectively prevents the purified gas from leaking from the connection gap between the purification tank 201 and the filter tank 1, ensuring the sealing performance of the device. If some gas is not completely purified or requires secondary treatment during the purification process, it can be returned to the device through the circulation pipe 203 connected to the bottom of the outer wall of the purification tank 201 for secondary filtration and purification, ensuring the gas purification effect. The clean gas that meets the standards after multi-stage filtration and purification is discharged from the device through the exhaust pipe 202 connected to the top of the outer side of the filter tank 1, and supplied to downstream gas-using equipment. The maintenance mechanism 3, which is fixedly connected to the bottom of the outer wall of the purification mechanism 2, replaces or cleans the easily worn parts such as the screen 205 and the filter element 206 in the purification mechanism 2, ensuring the long-term stable operation of the device.
[0038] The maintenance mechanism 3 is based on the fixed ring 301, which is securely connected to the middle of the inner side of the filter tank 1, providing an installation reference for the maintenance mechanism 3. The top fixing bracket 302 and the connecting ring 303 form a rotatable connection structure. When it is necessary to maintain internal components such as the screen 205 and filter element 206, the connecting ring 303 can be rotated to open the maintenance channel. When closed, the connecting ring 303 is fastened to the corresponding components by multiple screws 304 around the bottom, ensuring the sealing of the maintenance mechanism 3 after closure. The connecting component 305 at the bottom of the outer wall of the fixed ring 301 further enhances the structural stability and sealing performance: the support ring 3051 is fixed inside the fixed ring 301. In the middle, the support frame 3052, which runs through the bottom of its inner wall, supports and positions the main components of the purification tank 201, preventing shaking caused by airflow impact during operation. The fixing frame 3055 cooperates with the fixing sleeve 3054 to reinforce the connection between the fixing ring 301 and the filter tank 1 from the bottom, while the sealing gasket 3053 at the top of the fixing sleeve 3054 enhances the sealing of the connection, preventing gas leakage from gaps and ensuring that the device can still operate stably after maintenance. The maintenance mechanism 3, through its rotatable connection structure, multi-point fastening design and sealing components, not only realizes the quick disassembly and installation of purification components, but also ensures the structural stability and gas sealing of the device during normal operation.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
