Description
Technical field
Field is utilized the invention belongs to pressure energy of natural gas, is related to the band overload built in a kind of gas pipeline and adjusts automatically
The TRT of section.
Background technology
At present during gas ductwork management, it is impossible to carry out good early warning to accident in time, in reply gas pipeline
Before the crisis incident surfaces such as large area leakage, blast, management and dispatching means are pale and weak.Complete gas ductwork monitoring system for
Being normally carried out for combustion gas operation is extremely important.One automaticity height, the monitoring system of perfect in shape and function can be greatly enhanced
Operating efficiency, it is ensured that combustion gas operation security, reliable operation.
All webs' watch is realized, it is necessary to set monitoring device in the range of certain intervals, and monitoring device needs electric power to tie up
Hold operation.Due to more than control point and it is many be located at remote districts, it is too high to be that instrument specially pulls an electric wire cost, and examination ＆ approval are multiple
It is miscellaneous, therefore be badly in need of finding a kind of method that can provide electric energy to instrument on the spot.
The pressure of gas distributing system is far above the pressure required for user, and containing has huge pressure energy, utilizes pressure energy
Generate electricity on the spot for instrument using being a kind of realistic plan.Traditional pressure energy greatly and is needed very much using installation area
Staff operates, and is not generally applicable to as instrument power supply.Therefore, a kind of built in pipeline explosion-proof power generator simple in construction is developed
With practicable meaning, class instrument function demand can be met under conditions of low cost, and can flexibly transport installed in each
Plant the place of existing gas ductwork.
Chinese invention patent application CN 101280723A are for pressure reductions such as high-pressure natural gas point defeated station, urban gate stations
In cause the problem of huge energy is lost, disclose a kind of natural gas pipe network pressure energy gas turbine working domain recovery profit
Use method and device.The invention completes natural gas decompression pressure regulation process from vortex tube, and compressor is cooled down with cryogenic natural gas stream
Air inlet, increase air-mass flow, thus be greatly improved the economy of gas turbine, pressure energy has been obtained effectively
Utilize, but the patent is not generated electricity using pressure energy.Chinese invention patent application CN 101245956A are by pressure energy of natural gas
For expansion power generation, liquefied natural gas itself heavy component（Such as C2, C3Deng）And pressure energy is converted into cold energy work further
Using.Pressure energy is converted into cold energy by the invention with relatively low operating cost, and freezer, the cold water on voltage regulating station periphery are supplied by refrigerant
The cold users such as air-conditioning, waste old deep cooling crush use, or ice cube, dry ice product outward transport sale etc. is made, so as to obtain huge
Big economic benefit, improves efficiency of energy utilization.But the invention is not directed to generate electricity, and because the invention institute extracting method more theorizes,
Industrial practical application is larger.The A of Chinese invention patent application CN 101852529 disclose one kind and utilize gas distributing system pressure
The Efficient utilization method that power can freeze for freezer and cooling water air conditioner technique, but the same technology is not directed to pressure energy and generated electricity
Journey.These above-mentioned patented technologies are all that the technical method of natural gas pipe network pressure energy is effectively reclaimed by particular device, and are generated electricity
Shi Yaoqiu gas pressures drop and flow is stablized relatively, typically require that cryogenic temperature is relatively low during refrigeration, so in the presence of certain office
It is sex-limited.Chinese invention patent application CN203430574U discloses the dress that a kind of utilization mini gas pipe network pressure energy generates electricity
Put, but the patent mainly for voltage regulating station, measuring station etc. these can be interrupted, closure, small-power（1-5KW）Small user.
Therefore, whether from generated output, floor space and equipment, operating cost consider that the patent is unsuitable for being used for pipe network instrument
Table generates electricity, and pipe network instrument particularly from far-off regions generates electricity.
Above-mentioned existing patent is not directed to generate electricity for the mini gas pipe network of instrument power generation, and pipe network instrument at present
Table builds power network or existing pressure energy utilizes device, economy because of its various Special geographical position and the need for electricity of very little
It is all too poor with flexibility.Chinese invention patent application CN105065066A discloses a kind of pipeline to built-in TRT, but
The device does not consider the fluctuation problem of gas flow.The fluctuation of downstream gas consumption causes the ripple of gas discharge in pipeline
Dynamic, violent flowed fluctuation can cause to damage to the impeller and generator of built in pipeline TRT.Once damage, it is necessary to cut
The corresponding upstream pipeline section that breaks is re-replaced, and this not only wastes time and energy, and is also diffused substantial amounts of natural gas and is caused waste.Therefore, for managing
The built in pipeline TRT of net instrument power supply not only wants simple in structure and low in cost, can flexibly transport installed in various existing
The place of gas ductwork, should also possess corresponding overload regulatory function, it is ensured that built in pipeline TRT it is steady in a long-term
Operation.
