Description

Technical Field

[0001] This application relates to the field of flue gas treatment and fire safety technology, and in particular to a flame arrester for flue gas treatment pipelines. Background Technology

[0002] Flame arresters in flue gas treatment pipelines are key safety components in flue gas purification systems in chemical, metallurgical, and waste incineration industries. Their core function is to block the flame propagation path through metal mesh, corrugated plates, or ceramic honeycomb structures, while allowing high-temperature flue gas to pass through and complete post-treatment processes such as dust removal and desulfurization. With increasingly stringent environmental regulations and the trend towards larger industrial installations, flame arresters must operate stably for extended periods in high-temperature, highly corrosive media and complex impurity environments, and must be adaptable to harsh conditions such as frequent start-ups and shutdowns and airflow pulsations. Currently, the industry generally adopts a design mode of static flame arresters combined with flange bolt fixation, relying on periodic manual cleaning or high-pressure backflushing to maintain flow efficiency, and passively ensuring the airtightness of pipeline connections through gaskets and fasteners.

[0003] Traditional flue gas duct flame arresters have some technical drawbacks: First, flame arresters exposed to dusty flue gas for a long time are prone to local blockage due to particulate matter deposition. Manual cleaning requires shutdown and disassembly, and it is difficult to completely remove the tar or crystals adhering to the slits, resulting in a decrease in flame arresting efficiency and even the risk of backfire. Second, flange connections rely on bolt preload to maintain a seal. Under thermal expansion vibration or airflow impact, minor leaks are prone to occur due to gasket creep or bolt loosening. Leak point detection is difficult, and re-tightening operations in high-altitude pipe racks are risky. Utility Model Content

[0027] This application discloses a flame arrestor for flue gas treatment pipelines.

[0028] Please see Figures 1 to 4 A flame arrester for flue gas treatment ducts includes a rotating structure 3 for internal cleaning and a fixing structure 2 for fixing external ducts. The rotating structure 3 is fixedly installed on one side of the fixing structure 2 and is installed inside a flexible hose 5.

In the rotating structure 3, the first ring 31 supports and connects the components, and the connecting rod 34 on one side extends downward to connect to the second ring 35. The bottom of the second ring 35 has a rotating shaft 32, and the rotating ring 33 on the outside of the rotating shaft 32 can rotate with the rotating shaft 32. The second agitator 37 on the outside of the rotating ring 33 and the agitator 36 that cooperate with it can stir and clean the inside of the flame arrester during the rotation, preventing the accumulation of impurities from affecting the flame arresting effect.

[0030] Please see Figures 1 to 4 The fixed structure 2 includes a circular tube 21. A washer 22 is fixedly connected to one side of the circular tube 21. A limiting ring 23 is fixedly connected to one side of the washer 22. A plurality of fixing blocks 26 are fixedly connected to one side of the limiting ring 23. A push rod 24 and a push rod 29 are provided on one side of the fixing block 26. A slider 25 is slidably connected to the middle of the push rod 24 and the push rod 29. Friction rings 28 are fixedly connected to the outer sides of the push rod 24 and the push rod 29. A limiting ring 27 is fixedly connected to the outer side of the limiting ring 23.

[0031] It should be explained that the circular tube 21 of the fixed structure 2 can support and connect components. The gasket 22 on one side can buffer pressure and enhance sealing. The limiting ring 23 on one side of the gasket 22 and the limiting ring 27 on the outside can restrict the position of the components and prevent displacement. Multiple fixing blocks 26 on one side of the limiting ring 23 fix and support the components. The push rod 24 and push rod 29 on one side of the fixing block 26 can generate thrust. The slider 25 in the middle of the two can slide to adjust the magnitude and direction of the thrust. The friction ring 28 on the outside can increase friction, making the fixation more stable and ensuring reliable connection between the flame arrester and the pipeline.

[0032] Please see Figures 1 to 4 The fixing structure 2 is installed inside the box 1, and the connecting plate 4 is fixedly connected to the outside of the box 1.

[0033] It should be explained that the fixing structure 2 is installed inside the housing 1. It is responsible for firmly fixing the internal components of the flame arrester to ensure that it does not shake or shift during operation. The housing 1 provides protection and installation space for the internal structure, and the connecting plate 4 fixedly connected to its outer side facilitates the connection of the flame arrester to external pipes or other equipment, ensuring that the flue gas can smoothly enter the flame arrester for treatment.

[0034] Please see Figures 1 to 4 A flexible hose 5 is provided on one side of the connecting plate 4, and the flexible hose 5 is installed inside the housing 1.

[0035] It should be explained that the connecting plate 4 on the outside of the housing 1 connects to external components, and a flexible hose 5 is provided on one side of the connecting plate 4. This flexible hose 5 is installed inside the housing 1. It can bend flexibly to adapt to the internal spatial layout of the housing 1, transport flue gas, and allow the flue gas to smoothly enter the flame arrester for treatment.

[0036] Please see Figures 1 to 4 A rotating structure 3 is provided on one side of the connecting plate 4, and a ring 31 is provided on the outer side of the rotating structure 3.

[0037] It should be explained that a rotating structure 3 is provided on one side of the connecting plate 4.

[0042] The implementation principle of a flame arrester for a flue gas treatment pipeline according to an embodiment of this application is as follows:

[0043] First, when the flame arrester in the flue gas treatment pipeline is working, the fixed structure 2 is supported by the round pipe 21, the gasket 22 buffers the pressure and enhances the sealing, the limiting ring 1 23 and the limiting ring 27 restrict the position of the components, the fixed block 26 provides fixed support, the push rod 1 24 and the push rod 29 generate thrust, the slider 25 adjusts the magnitude and direction of the thrust, and the friction ring 28 increases the friction, so that the flame arrester is firmly installed on the external pipeline, ensuring that the internal components do not shake or shift during operation.

[0044] Secondly, the rotating structure 3 begins to operate. It is installed inside the hose 5, with the first ring 31 supporting and connecting the components, and the connecting rod 34 extending downward to connect to the second ring 35. The rotating shaft 32 at the bottom of the second ring 35 drives the rotating ring 33 to rotate, and the second agitator 37 and the first agitator 36 on the outside of the rotating ring 33 rotate accordingly, stirring and cleaning the inside of the flame arrester to prevent impurities from accumulating and affecting the flame arresting effect, and ensuring the smooth flow of flue gas treatment.

[0045] Finally, the flue gas enters the flame arrester through the connecting plate 4. The connecting plate 4 connects to external components, and the hose 5 is installed inside the housing 1 to transport the flue gas into the flame arrester. During the flue gas treatment process, the limiting ring 23 restricts the rotation range of the rotating ring 33 to prevent component misalignment, ensure stable equipment operation, and allow the flue gas to pass smoothly through the flame arrester before being discharged.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
