Description

Technical Field

[0001] This utility model relates to the field of natural gas production site protection technology, specifically a fireproof isolation device for natural gas production sites. Background Technology

[0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere. Natural gas is stored in porous underground rock formations, including oilfield gas, gas field gas, coalbed methane, mud volcano gas, and biogenic gas, with a small amount also found in coal seams. It is a high-quality fuel and chemical raw material. During the production process, natural gas is transported through natural gas pipelines. At the production site, some devices need to be designed to protect the natural gas pipelines to prevent them from bursting when exposed to fire.

[0003] According to a patent application published on the internet (authorization announcement number: CN212564924U), "This utility model provides a liquefied natural gas (LNG) transportation pipeline, relating to the field of LNG transportation technology, including: an inlet pipe, a filter cylinder, a first connecting cylinder, a second connecting cylinder, a drain pipe, a filter structure, a spiral rod, a filter screen, a valve, a connecting block, a first sealing block, a snap fastener, a second sealing block, a bearing, a heat insulation layer, a rubber layer, a wear-resistant layer, and an anti-corrosion layer. The first connecting cylinder is fixedly connected to one end of the filter cylinder, and the second connecting cylinder is movably connected to the other end of the first connecting cylinder. This utility model, by setting up a filter cylinder, a first connecting cylinder, a second connecting cylinder, a drain pipe, a filter structure, a spiral rod, and a filter screen, enables the LNG transportation pipeline to filter impurities inside the LNG during LNG transportation. Simultaneously, the impurities can be centrally cleaned by removing the filter screen, thus improving the cleanliness of the impurities."

[0004] Based on the above, the applicant believes the following deficiencies exist:

[0005] The liquefied natural gas (LNG) transport pipeline includes an inlet pipe, a filter cylinder, a connecting cylinder one, a connecting cylinder two, a drain pipe, a filter structure, a screw rod, a filter screen, and valves. By incorporating these components, the pipeline allows for the filtration of impurities within the LNG during transport. The filter screen can be removed for centralized cleaning of these impurities, making the process easier. However, during transport, leaks may occur at the connection points. Natural gas exposed to fire can explode, causing severe damage to the production site and posing a hazard to workers. The overall sealing and protection of the components in this device are poor, failing to provide adequate fire protection. Utility Model Content
