Description
Technical field
It is built on stilts combustion gas heat-preserving anti-freezing pipeline and its application method specifically the present invention relates to electric tracing technology.
Background technology
Combustion gas main source is that based on liquefied oil gas, coal gas and mixing air, fuel gas transmission mode uses Gas Pipe
Road.Natural gas (associated gas for including oil field production) is transported to urban gas center or industrial enterprise from exploitation ground or treatment plant
The pipeline of user, also known as gas pipeline.
Patent document 201510695214.X (the applyings date：2015.10.23) disclose a kind of antifreeze house lead in of self-loopa combustion gas
Device, it is intended to solve cold district winter gas house pipe because low temperature causes mass sets in combustion gas, the pipeline in turn resulted in
Frozen block problem.The device includes：Gas inlet pipe, Gas Pipe external thermal insulation and Gas Pipe house lead in valve, wherein gas inlet pipe
It is divided into indoor section and outdoor section, it is characterized in that piece combustion gas circulation of connection between the indoor section and outdoor section of gas inlet pipe
Pipe, the outdoor section of wherein combustion gas circulation pipe adds heat-insulation layer, and gas inlet pipe constitutes peripheral passage with combustion gas circulation pipe.
The present invention is simple in construction, it is not necessary to any plant equipment power, without other any energy losses, it is adaptable to civilian to build
Build and public building gas house pipe network.Significantly, the density contrast caused using the temperature difference provides power to antifreezing effect, and then is formed
Circulate, indoor heat is effectively passed into outdoor section gas inlet pipe.
But above-mentioned patent document mainly solve be ground connection install gas pipeline, especially solve ground connection install combustion
The introducing tube portion of feed channel, due to being restricted by conditions such as landform, house architectural structures, Some gases pipeline buried can not be applied
If the then use for combustion gas has further improvement, is mainly manifested in installing for gas pipeline, pacified by past ground connection
Dress is changed into hanging installation.The gas pipeline vacantly installed is not possess calorific capacity in itself, and simple insulation can not solve knot
The problem of dew freezes.The main cause that condensation freezes is that water and steam can be generated with gaseous C2, C3 and C4 and crystallized in coal gas
Hyrate, hyrate can reduce the circulation section of coal gas in pipeline, or even block pipeline.Condensation, which freezes, not only influences the defeated of pipeline
Ability is sent, also in the presence of very big potential safety hazard.Solve the condensation ice formation issues of wet combustion gas, it is necessary to overhead gas pipeline
Do heat tracing and isothermal holding.
Using under hanging installation situation, the laying of pipeline is not restricted by conditions such as landform, house architectural structures, but anti-
The difficulty for freezing insulation is increased, and with the development of science and technology, now uses the heat tracing measure anti-freezing and heat-insulating of vortex deforst technique, for example
《Oil-gas field surface engineering》The Study on processing method for the gas pipeline frozen block that the 6th phase of volume 28 in 2009 delivers, author Liu Wenyang,
Pipeline frozen block mostly occurs to be introduced at the introducing pipe of pipe, pressure regulating box and batch meter in cell unit, because introducing tube portion is in ground
On, it is partially in underground.Solving frozen block has two approach, and one is prevented before frozen block is formed；Two are formed in frozen block
Solved afterwards using the means of physics and chemistry.The measure taken includes setting up water trap, the management for strengthening equipment and application vortex
Not damaged deforst technique etc..
It is to convert electrical energy into magnetic field to be vortexed deforst technique, and magnetic field converts the technology of heat energy.Cable, which is wrapped in, to thaw
Pipeline on, then cable is formed the device of similar magnetic coil, the center maximum intensity in magnetic field, so producing
Heat radially carries out thermograde change by pipe center along pipeline, within a certain period of time discharges the ice-out inside pipeline.
The technology does not destroy heat-insulation layer, and conveyance conduit can be made to thaw and recover normal.
But vortex deforst technique is thawed after being frozen suitable for pipeline condensation, for antifreezing effect before pipeline condensation icing simultaneously
It is bad, if being always maintained at electric cable heating, energy waste certainly will be caused.
