Description

Technical Field

[0001] The utility model relates to the technical field of natural gas, and more specifically to a natural gas pipeline filter. Background Art

[0002] Natural gas refers to a type of combustible gas that exists in nature. It is a fossil fuel, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere. There are a large number of solid and liquid impurities in the raw natural gas obtained from mining. These impurities determine that the raw gas cannot be directly delivered to end users. In other words, the natural gas delivered to end users must be treated with impurity removal and filtration, so pipeline filters will be used.

[0003] Existing natural gas pipeline filters filter natural gas through a filter screen. However, after long-term use, a lot of impurities may stick to the filter screen, which may cause the filter screen mesh to be clogged, affecting the transportation efficiency of natural gas. Replacing the filter screen requires disassembling the pipeline or the filter assembly, which is cumbersome and inconvenient and has certain limitations. Utility Model Content
