Description

Technical Field

[0001] This utility model relates to the field of flame arrestor technology, specifically a filter-type pipeline flame arrester with a multi-stage isolation structure. Background Technology

[0002] A pipeline flame arrester is a safety device used to prevent the outward spread of a hydrogen flame. It consists of a solid material (flame-arresting element) that allows gas to pass through and has many tiny channels or gaps. The gaps or channels of the flame-arresting element are required to be as small as possible, so that when the flame enters the flame arrester, it is divided into many small flame streams by the flame-arresting element. Due to heat transfer (gas is cooled) and the wall effect, the flame streams are extinguished.

[0003] Existing pipeline flame arresters have certain shortcomings in terms of filtration and flame arrest, so a new design was developed to address these issues. Utility Model Content

[0004] To solve the problems mentioned above, this utility model is achieved through the following technical solution: a filter-type pipeline flame arrester with a multi-stage isolation structure, including a flame arresting device, wherein a cleaning device is fixedly connected to one side of the outside of the flame arresting device;

[0005] The flame arrestor includes a flame arrestor housing. A filter plate is fixedly connected to one side of the inner wall of the flame arrestor housing to filter impurities in the flame, protect the flame arrestor structure, stabilize the medium flow, and avoid the risk of "detonation." A flame arrestor frame is fixedly connected to the middle of the inner wall of the flame arrestor housing. A flame arrestor element is fixedly connected to the inner side of the flame arrestor frame. Through a "flame quenching" mechanism, it directly cuts off the flame propagation and prevents backfire by "blocking the backfire path," ensuring a balance between medium flow and flame arrestor function. A multi-level isolation mechanism is fixedly connected to the side of the inner wall of the flame arrestor housing away from the filter plate to construct a "multi-layer flame quenching barrier," significantly improving flame arrestor reliability, coping with "extreme combustion scenarios," expanding the scope of flame arrestor application, ensuring long-term operational stability, and reducing the risk of "functional degradation." A friction mechanism is fixedly connected to the side of the filter plate away from the flame arrestor element. The friction mechanism rotates to rub the outer side of the filter plate, thereby cleaning impurities on the surface of the component, preventing the filter plate holes from becoming clogged, clearing channel blockage, restoring the "flame quenching" capability, reducing media flow resistance, ensuring normal equipment operation, reducing impurity corrosion, and extending the life of the flame arrestor core. A chip discharge port is opened on the outer side of the flame arrestor shell near the filter plate. The outer side of the flame arrestor shell near the chip discharge port is fixedly connected to the outer side of the cleaning device, which cleans impurities inside the pipe, prevents particles from accumulating inside the pipe, prevents affecting flame flow efficiency, prevents blockage inside the pipe, restores the effectiveness of the "flame quenching channel", avoids backfire or explosion, and eliminates additional safety risks caused by "abnormal flow field".

[0006] Preferably, the friction mechanism includes an outer end, with a connecting shaft rotatably connected to the inner side of the outer end. A friction bracket is fixedly connected to the outer side of the connecting shaft near the filter plate, so that the friction bracket controls the scraper to rub the outer side of the filter plate, thereby cleaning impurities on the surface of the component, preventing the filter plate holes from becoming blocked, thus clearing channel blockage, restoring the "flame quenching" capability, reducing media flow resistance, ensuring normal equipment operation, reducing impurity corrosion, and extending the life of the flame arrestor core. A scraper is fixedly connected to the outer side of the friction bracket away from the connecting shaft, and a first paddle is fixedly connected to the outer side of the connecting shaft away from the scraper.

[0007] Preferably, the multi-level isolation mechanism includes an isolation shell, the outer side of which is fixedly connected to the inner wall of the flame-arresting shell. An upper side plate is fixedly connected to one side of the inner wall of the isolation shell, and fine holes are formed on the outer side of the upper side plate. A lower side plate is fixedly connected to the inner wall of the isolation shell near the upper side plate. The flame passes through the upper and lower side plates, thereby forcing the flame to "detour", lengthening the propagation path, enhancing "heat exchange", rapidly cooling the flame, dividing the flame front, and weakening the combustion intensity. Coarse holes are formed on the outer side of the lower side plate, and the flame flows alternately from the fine holes to the coarse holes. This adapts to low flow rate and high safety scenarios, balances "flame arrest" and "medium flow", reduces medium flow resistance, and ensures normal delivery. This constructs a "multi-layer flame quenching barrier", significantly improves the reliability of flame arrest, copes with "extreme combustion scenarios", expands the application range of flame arrest, ensures long-term operational stability, and reduces the risk of "functional decay".

[0008] Preferably, the cleaning device includes an outer housing, the top of which is fixedly connected to the outside of the flame arrestor housing. A valve plate is fixedly connected to the outside of the outer housing to prevent flames from entering the equipment and causing damage. An external pipe is fixedly connected to the outside of the outer housing away from the flame arrestor housing. A scraping mechanism is fixedly connected to the inner wall of the external pipe. A fan is fixedly connected to one side of the external pipe. Impurities flow through the external pipe toward the fan, thereby removing internal impurities, preventing particles from accumulating inside the pipe, preventing the flame flow efficiency from being affected, preventing blockage inside the pipe, restoring the effectiveness of the "flame quenching channel", avoiding backfire or explosion, and eliminating additional safety risks caused by "abnormal flow field".

[0009] Preferably, the wall scraping mechanism includes a receiving shaft, an outer column rotatably connected to the outer side of the receiving shaft, a second paddle fixedly connected to the middle of the outer side of the outer column, and wall scraping brackets fixedly connected to both sides of the outer side of the outer column. The wall scraping brackets control the wall scraping column to rub against the inner wall of the pipe. The wall scraping column is rotatably connected between the opposite surfaces of the wall scraping brackets, which plays a role in cleaning impurities on the inner wall of the pipe, reducing the accumulation of impurity particles on the inner wall of the pipe, avoiding excessive accumulation that affects the airflow or particle flow effect, preventing the chip removal effect, and further reducing impurity residue, thereby keeping the inside of the equipment clean.

[0010] Preferably, a silicone block is fixedly connected to the outer side of the scraping column. The silicone block is made of ceramicized silicone, which has a high temperature resistance, thereby reducing rigid collisions between components, reducing wear between components, and extending the service life of the components. The outer side of the silicone block has a strip groove to optimize the friction interface, improve the adaptability of use, disperse frictional heat, prevent "local overheating aging", adapt to irregular friction surfaces, and improve friction sealing or positioning.

[0011] Beneficial effects

[0012] This utility model provides a filter-type pipeline flame arrester with a multi-stage isolation structure. It has the following beneficial effects:

[0013] 1. This filter-type pipeline flame arrester with a multi-stage isolation structure, through its flame arresting device design, allows the flame to enter from the side of the flame arresting housing near the filter plate. The filter plate then filters impurities from the flame. The flame passes through the flame arresting element and the multi-stage isolation mechanism, thus constructing a "multi-layer flame quenching barrier," significantly improving flame arresting reliability, coping with "extreme combustion scenarios," expanding the scope of flame arresting applications, ensuring long-term operational stability, reducing the risk of "functional decay," and thereby achieving the flame arresting effect of the equipment.

[0014] 2. This filter-type pipeline flame arrester with a multi-stage isolation structure forces the flame to "detour," lengthening its propagation path, enhancing heat exchange, rapidly cooling the flame, dividing the flame front, and weakening the combustion intensity. The flame flows alternately from the fine pores to the coarse pores, thus adapting to low-flow-rate, high-safety scenarios, balancing "flame arrest" and "medium flow," reducing medium flow resistance, and ensuring normal delivery. This effectively constructs a "multi-layer flame quenching barrier," significantly improving flame arrest reliability, addressing "extreme combustion scenarios," expanding the flame arrestor's applicable range, ensuring long-term operational stability, and reducing the risk of "functional degradation."

[0015] 3. This filter-type pipeline flame arrester with a multi-stage isolation structure, through its cleaning device design, uses a fan to generate airflow to absorb impurities inside the flame arrester housing. The impurities flow towards the fan side through an external pipe, thereby removing internal impurities, preventing particles from accumulating inside the pipeline, preventing the flame flow efficiency from being affected, preventing blockage inside the pipeline, restoring the effectiveness of the "flame quenching channel", avoiding backfire or explosion, and eliminating additional safety risks caused by "abnormal flow field".

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a filter-type pipeline flame arrester with a multi-level isolation structure, including a flame arresting device 1, and a cleaning device 2 fixedly connected to one side of the outside of the flame arresting device 1.

[0025] The flame arresting device 1 includes a flame arresting housing 11. A filter plate 12 is fixedly connected to one side of the inner wall of the flame arresting housing 11. A flame arresting frame 13 is fixedly connected to the middle of the inner wall of the flame arresting housing 11. A flame arresting element 14 is fixedly connected to the inner side of the flame arresting frame 13. A multi-stage isolation mechanism 16 is fixedly connected to the side of the inner wall of the flame arresting housing 11 away from the filter plate 12. A friction mechanism 15 is fixedly connected to the side of the filter plate 12 away from the flame arresting element 14. A chip discharge port 17 is opened on the side of the flame arresting housing 11 near the filter plate 12. The side of the flame arresting housing 11 near the chip discharge port 17 is fixedly connected to the outside of the cleaning device 2. The flame enters from the side of the flame arrestor housing 11 near the filter plate 12, filtering impurities from the flame, protecting the flame arrestor structure, stabilizing media flow, and avoiding the risk of "detonation." A friction mechanism 15 is installed on the side of the filter plate 12 near the flame inlet. The kinetic energy generated by the flame flow acts on the outer side of the friction mechanism 15, causing it to rotate and rub against the outer side of the filter plate 12. This cleans impurities from the component surface, preventing blockage of the filter plate 12's pores, clearing channel blockages, restoring the "flame quenching" capability, reducing media flow resistance, ensuring normal equipment operation, reducing impurity corrosion, and extending the life of the flame arrestor core. The cleaned impurities settle towards the chip discharge port 17 as the flame kinetic energy dissipates, where the cleaning device 2 absorbs the particles or impurities, thus achieving... The function of cleaning impurities inside the pipeline is to prevent particles from accumulating inside the pipeline, to prevent affecting the flame flow efficiency, to prevent blockage inside the pipeline, to restore the effectiveness of the "flame quenching channel", to avoid backfire or explosion, and to eliminate additional safety risks caused by "abnormal flow field". The flame flows through the filter plate 12 to the flame arrestor element 14. The flame arrestor element 14 directly cuts off the flame propagation through the "flame quenching" mechanism. By "blocking the backfire path", it prevents the flame from igniting in reverse and ensures the balance between medium flow and flame arresting function. A multi-level isolation mechanism 16 is set on the other side of the inner wall of the flame arrestor shell 11. The multi-level isolation mechanism 16 is used to build a "multi-layer flame quenching barrier", which greatly improves the reliability of flame arresting, copes with "extreme combustion scenarios", expands the scope of application of flame arresting, ensures long-term operational stability, and reduces the risk of "functional decay".

[0026] The friction mechanism 15 includes an outer end 151, with a connecting shaft 152 rotatably connected to the inner side of the outer end 151. A friction bracket 153 is fixedly connected to the outer side of the connecting shaft 152 near the filter plate 12. A scraper 154 is fixedly connected to the outer side of the friction bracket 153 away from the connecting shaft 152. A first paddle 155 is fixedly connected to the outer side of the connecting shaft 152 away from the scraper 154. The kinetic energy generated by the flame flow acts on the outer side of the first paddle 155, causing the first paddle 155 to drive the connecting shaft 152 to rotate. This causes the friction bracket 153 to control the scraper 154 to rub against the outer side of the filter plate 12, thereby cleaning impurities from the surface of the component. This prevents the holes in the filter plate 12 from becoming clogged, thus clearing channel blockages, restoring the "flame quenching" capability, reducing media flow resistance, ensuring normal equipment operation, reducing impurity corrosion, and extending the life of the flame arrestor core.

[0027] The multi-level isolation mechanism 16 includes an isolation shell 161. The outer side of the isolation shell 161 is fixedly connected to the inner wall of the flame arrestor shell 11. An upper side plate 162 is fixedly connected to one side of the inner wall of the isolation shell 161. A fine hole 163 is opened on the outer side of the upper side plate 162. A lower side plate 164 is fixedly connected to the inner wall of the isolation shell 161 near the upper side plate 162. A coarse hole 165 is opened on the outer side of the lower side plate 164. The upper side plate 162 and the lower side plate 164 are evenly arranged on the inner wall of the isolation shell 161. The flame flows through the fine holes 163 of the upper side plate 162 to the coarse holes 165 of the lower side plate 164, thereby forcing the flame to "detour", lengthening the propagation path, strengthening "heat exchange", rapidly cooling the flame, dividing the flame front, and weakening the combustion intensity. The flame flows alternately from the fine holes 163 to the coarse holes 165, thereby adapting to low flow rate and high safety scenarios, balancing "flame arrest" and "medium flow", reducing medium flow resistance, and ensuring normal delivery. This constitutes a "multi-layer flame quenching barrier", greatly improving the reliability of flame arrest, coping with "extreme combustion scenarios", expanding the scope of flame arrest application, ensuring long-term operational stability, and reducing the risk of "functional degradation".

[0028] Please see Figure 5-6The cleaning device 2 includes an outer housing 21. The top of the outer housing 21 is fixedly connected to the outside of the flame arrestor housing 11. A valve plate 22 is fixedly connected to the outside of the outer housing 21. An external pipe 23 is fixedly connected to the outside of the outer housing 21 away from the flame arrestor housing 11. A scraping mechanism 25 is fixedly connected to the inner wall of the external pipe 23. A fan 24 is fixedly connected to one side of the external pipe 23. The valve plate 22 controls the closure of the outer housing 21 to prevent flames from entering the equipment and causing damage. When the flame stops flowing, the fan 24 generates airflow to absorb impurities inside the flame arrestor housing 11. The impurities flow through the external pipe 23 to the fan 24, thereby removing internal impurities, preventing particles from accumulating inside the pipe, preventing the flame flow efficiency from being affected, preventing blockage inside the pipe, restoring the effectiveness of the "flame quenching channel", preventing backfire or explosion, and eliminating additional safety risks caused by "abnormal flow field".

[0029] The wall-scraping mechanism 25 includes a receiving shaft 251, an outer column 252 rotatably connected to the outer side of the receiving shaft 251, a second paddle 253 fixedly connected to the middle of the outer side of the outer column 252, and wall-scraping supports 254 fixedly connected to both sides of the outer side of the outer column 252. A wall-scraping column 255 rotatably connects between the opposing surfaces of the wall-scraping supports 254. The wind force generated by the fan 24 acts on the second paddle 253, causing the second paddle 253 to drive the outer column 252 to rotate. This causes the wall-scraping supports 254 to control the wall-scraping columns 255 to rub against the inner wall of the pipe, thereby cleaning impurities from the inner wall of the pipe, reducing the accumulation of impurity particles on the inner wall of the pipe, avoiding excessive accumulation that could affect airflow or particle flow, preventing impact on chip removal efficiency, and further reducing impurity residue, thus keeping the inside of the equipment clean.

[0030] A silicone block 256 is fixedly connected to the outer side of the scraper column 255, and a strip-shaped groove 257 is formed on the outer side of the silicone block 256. The silicone block 256 is made of ceramicized silicone material, which has a high temperature resistance. When the silicone block 256 rotates with the scraper column 255, it reduces rigid collisions between components, reduces wear between components, and thus extends the service life of the components. The strip-shaped groove 257 optimizes the friction interface, improves the adaptability of use, disperses frictional heat, prevents "local overheating aging", adapts to irregular friction surfaces, and improves friction sealing or positioning.

[0031] During operation, the flame enters from the side of the flame arrestor housing 11 near the filter plate 12, filtering impurities from the flame, protecting the flame arrestor structure, stabilizing media flow, and avoiding the risk of "detonation." A friction mechanism 15 is installed on the side of the filter plate 12 near the flame inlet. The kinetic energy generated by the flame flow acts on the outer side of the friction mechanism 15, causing it to rotate and rub against the outer side of the filter plate 12. This cleans impurities from the component surface, preventing blockage of the filter plate 12's pores, clearing channel blockages, restoring the "flame quenching" capability, reducing media flow resistance, ensuring normal equipment operation, reducing impurity corrosion, and extending the life of the flame arrestor core. The cleaned impurities settle towards the chip discharge port 17 as the flame kinetic energy dissipates, where the cleaning device 2 absorbs the particles or impurities. This system effectively cleans impurities inside the pipe, preventing particle accumulation, ensuring efficient flame flow, preventing blockages, restoring the effectiveness of the "flame quenching channel," preventing backfire or explosion, and eliminating additional safety risks caused by "abnormal flow fields." The flame flows through the filter plate 12 to the flame arrestor element 14, which directly cuts off flame propagation through the "flame quenching" mechanism. By "blocking the backfire path," it prevents reverse ignition of the flame, ensuring a balance between medium flow and flame arresting function. A multi-level isolation mechanism 16 is set on the other side of the inner wall of the flame arrestor shell 11. This multi-level isolation mechanism 16 constructs a "multi-layer flame quenching barrier," significantly improving flame arresting reliability, addressing "extreme combustion scenarios," expanding the applicability of the flame arrestor, ensuring long-term operational stability, and reducing the risk of "functional degradation."
