Description
Technical field
The utility model belongs to natural fuels can transportation technology field, particularly relate to a kind of medium pressure gas pot type superimposed trailer, utilize the direct pipe network of pipe network pressure head to get in gas, the short distance to press transportation, be the equipment of the economic air feed of independent combustion gas user that closes on (in the radius 100km scope) pipe network.
Background technology
In recent years, along with the adjustment of China's energy mix, natural fuels becomes one of China's main energy sources gradually, along with " the enforcement of engineerings such as West-east Gas, " extra large gas lands ", " Russia send in gas south "; the shared energy proportion of natural fuels is with increasing, and the use of natural fuels is very universal.Along with the expansion gradually of natural fuels customer volume, carry the natural fuels storage that replenishes, the demand of transportation device to increase as gas ductwork thereupon.Because there is variation in domestic combustion gas operation form, traditional plenum system has pipe network reduce pressure direct air feed, way high pressure far away (20MPa) transportation decompression air feed, and the operation form is mainly invested the pipeline air feed, live on one's own life sub-district or independent industrial user's air feed.
Perforation along with natural fuels transfering natural gas from the west to the east high-pressure delivery pipeline, city natural gas pipe network is popularized, a kind of equipment (middle pressure transport trolley) that utilizes the direct pipe network of pipe network pressure head to get pressure transportation in gas, the short distance of market in urgent need development is the economic air feed of independent combustion gas user that closes on (in the radius 100km scope) pipe network, for combustion gas operator provides a kind of brand new operation way.
Summary of the invention
The purpose of this utility model is to provide a kind of medium pressure gas pot type superimposed trailer, has solved the combustion gas transportation and has replenished the problem that must use compressor in the process, transport difficulty, can not directly get gas.
