Description

Technical Field

[0001] This utility model relates to the field of transfer and transportation equipment technology, specifically to a transfer and transportation equipment for uniformly mixing natural gas and air in gas pipeline engineering. Background Technology

[0002] Natural gas is one of the safest fuels. It does not contain carbon monoxide and is lighter than air. If it leaks, it will immediately diffuse upwards and is not likely to accumulate and form an explosive gas. Its safety is relatively high compared to other fuels. Using natural gas as an energy source can reduce the use of coal and oil, thus greatly improving environmental pollution. As a clean energy source, natural gas can reduce sulfur dioxide and dust emissions by nearly 100%, carbon dioxide emissions by 60%, and nitrogen oxide emissions by 50%. It also helps reduce acid rain formation, mitigate the greenhouse effect, and fundamentally improve environmental quality.

[0003] Existing natural gas and air uniform mixing and transfer equipment used in gas pipeline projects cannot provide alarm processing in case of natural gas leakage during transportation, resulting in low safety during the transportation process. Therefore, there is an urgent need for a natural gas and air uniform mixing and transfer equipment for gas pipeline projects to solve the above-mentioned technical problems. Utility Model Content
