Description

Technical Field

[0001] The utility model relates to the field of liquid accumulation in natural gas pipelines, and in particular to a device for removing liquid accumulation in natural gas pipelines. Background Art

[0002] A natural gas pipeline refers to a pipeline that transports natural gas from a mining site or processing plant to a city gas distribution center or industrial enterprise user. It is also called a gas transmission pipeline. As natural gas is affected by changes in temperature and pressure during long-distance transportation, water and heavy hydrocarbon components in the natural gas are prone to gas-liquid phase change and precipitate during pipeline transportation. They cannot be completely removed, forming liquid accumulation in low-lying areas of undulating pipelines, leading to increased pipeline pressure, reduced transportation efficiency, and accelerated pipeline corrosion. In severe cases, it is easy to cause natural gas leakage and other problems. Therefore, long-distance natural gas transmission pipelines must be equipped with liquid removal devices to solve the many problems mentioned above.

[0003] However, the common natural gas pipeline liquid removal devices on the market currently require the transmission pipeline to be closed first and then the accumulated liquid to be discharged, which will affect the normal transportation of natural gas. If the transmission pipeline is not closed, the natural gas will be transmitted to the outside through the removal device, causing natural gas leakage. Utility Model Content
