Pressure energy of natural gas is used for expansion power generation, liquefied natural gas self heavy component (such as C2, C3Deng) and pressure can be converted into
Cold energy makees application further.Pressure can be converted into cold energy with relatively low operating cost by this utility model, by coolant for pressure regulation
The cold users such as the freezer of periphery, cooling water air conditioner, waste old deep cooling crush that stand use, or make ice cube, dry ice product outward transport
Sell, thus obtain great economic benefit, improve efficiency of energy utilization.But this utility model is not directed to generating, and because this is real
More theorizing with novel institute extracting method, industry practical application is bigger.Chinese utility model patent application CN
101852529 A disclose and a kind of utilize natural gas pipe network pressure energy refrigeration for the efficient utilization of freezer and cooling water air conditioner technique
Method, but this technology is not directed to pressure energy power generation process equally.These patented technologies above-mentioned are all effectively to be returned by particular device
Receive the technical method of natural gas pipe network pressure energy, and during generating, require that gas pressure fall is relative with flow stable, during refrigeration one
As require that cryogenic temperature is relatively low, so having some limitations.Chinese utility model patent application CN203430574U is open
A kind of device utilizing mini gas pipe network pressure energy to generate electricity, but this patent mainly for voltage regulating station, measuring station etc. these
Can be interrupted, closure, the small user of small-power (1-5KW).Therefore, whether from generated output, floor space and equipment, fortune
Going into original consideration, this patent is unsuitable for generating electricity for pipe network instrument, particularly the generating of remote districts pipe network instrument.
Above-mentioned existing patent is all not directed to generate electricity for the mini gas pipe network of instrument power generation, and pipe network instrument at present
Table, because of its various Special geographical positions and the least need for electricity, is built electrical network or existing pressure can be utilized device, economy
The poorest with motility.Chinese utility model patent application CN105065066A discloses a kind of pipeline to built-in generating dress
Put, but this device do not take into account the fluctuation problem of gas flow.The fluctuation of downstream gas consumption causes gas discharge in pipeline
Fluctuation, impeller and the electromotor of built in pipeline TRT can be caused damage by violent flowed fluctuation.Once damage, just need
Cutting off corresponding upstream pipeline section again to change, this not only wastes time and energy, and also diffuses substantial amounts of natural gas and causes waste.Therefore, use
Built in pipeline TRT in pipe network instrument power supply not only wants simple in structure and low in cost, can transport flexibly be arranged on various
The place of existing gas ductwork, also should possess corresponding overload regulatory function, it is ensured that built in pipeline TRT long-term
Stable operation.
