Description
Technical field
The present invention relates to a kind of natural gas and coal bed gas pipe transportation technology field, specially a kind of natural gas transportation system
System.
Background technology
Since 2012, there is always big face when Winter-Spring is communicated and the autumn and winter communicate in the North China in China, the regions such as the Yellow River and Huai He River
Long-pending haze weather, PM2.5 concentration belong to serious air pollution to hundreds of.Main cause is that coal and oil are extensive
It applies in industrial production and daily life, chimney tens of thousands daily, fuel combustion vehicle release volume of smoke and dioxy
Change sulphur.Mix in air, a kind of aerosol of stabilization is formed by complicated chemical reaction.Therefore, the use of coal is reduced
Exactly administer one of the effective means of haze.For this purpose, China, which started to advocate energetically in 2017, utilizes clean energy resource, using natural
Gas, solar power generation, water generating, the technologies such as wind-power electricity generation, while eliminating seriously polluted coal-burning boiler.Especially coal,
No matter industry or it is civilian gradually replace with natural gas, thus having raised vigorous coal, to change fate dynamic.In city, natural gas
It is very ripe managing defeated system, but the extensive country regions, always without the defeated system of natural gas tube, therefore also to establish corresponding
The defeated system of natural gas tube.Natural gas will pass through gas production, gas collection, purification, gas transmission, gas storage, gas transmission pipeline net work entrance from exploitation to user
User terminal, a defeated system of complete natural gas tube are the intermediate engineerings with connecting air source with user.Keep the defeated system of Gas Pipe
Stabilization safe operation be our technical problems to be solved.Whole device main material is the pipeline of various bores, main
Engineering concentrates on the laying of pipeline, and if China's West-East National Gas Transmission Project is related to thousands of miles, the pipeline laying of long range needs to wear mountain
More ridge, for the sake of security, the major part of gas pipeline are embedded in underground.Manage to consider the problems of in defeated system operation it is main
It is the cleaning problems inside pipeline service life and pipeline.Corrosive pipeline is a kind of FAQs, and the pipeline that we use is general
For iron pipe, if protection is not in place, wall erosion goes out perforation, then can cause serious leakage problem, and this corrosion is led
Come from the external world.Then due to the untreated clean dust carried in combustion gas inside pipeline, moisture long time sedimentation gradually forms
Aggregate and block pipeline, influence air input efficiency.
It would therefore be desirable to the outer wall anti-corrosion and internal cleaning of gas pipeline be solved the problems, such as, to ensure the defeated system of Gas Pipe
The operation steady in a long-term of system.
