Background technology
For the most of well opening natural gas difference electricity generation system announced at present, they use piston type or turbine type mostly
Formula generator system, two kinds also exist a problem exactly jointly: all have to pass through separator before it generates electricity and divide accordingly
From, because piston type generator can not enter with liquid or impurity, turbine type does not carry out magazins' layout and then can damage rapidly.
So both of which must separate in the separator, but the operating pressure of current separator is the highest, and this just will cause
Carrying out blood pressure lowering significantly before separation to process, result in substantial portion of pressure can not utilized.
Based on above-mentioned situation, this utility model utilizes three-apexed rotor engine (being formed by rotary polygonal piston engine transformation) to replace
TRT before, and devise new multilevel system in parallel, whole system has higher adaptation ability, can directly enter
Row differential pressure power generation and then sufficiently utilize pressure energy.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that utilize the plural parallel stage three of high-pressure gas pressure energy
Angle rotor dynamic machine, sufficiently utilizes pressure unnecessary in pipelined can be used for generating electricity.
This utility model utilize well head high-pressure natural gas pressure can multistage three-apexed rotor electricity generation system, mainly by gas well christmas tree,
Pressure regulator valve, reheater, three-apexed rotor engine, electromotor, switch valve are connected composition with natural gas line.Described gas well gas production
Tree is connected with pressure regulator valve, and pressure regulator valve is connected to reheater；The multistage three-apexed rotor exporting parallel connection two-strip structure identical of reheater moves
Power unit；Wherein a multistage three-apexed rotor powerplant module is at first order three-apexed rotor engine and second level three-apexed rotor engine
Between pipeline in the middle of accessed reheater, the concentric shafts of first order three-apexed rotor engine pass through second level three-apexed rotor engine
Axle be connected with electromotor；Leading portion in another multistage three-apexed rotor powerplant module is connected to switch valve, and then switch valve connects three
Angle rotor dynamic machine, then be linked in reheater, it is linked into three-apexed rotor engine the most again, is finally incorporated to during supervisor converges and tune
Pressure valve connects, and the concentric shafts of the multistage three-apexed rotor engine of this pipeline is connected with electromotor by the axle of three-apexed rotor engine.
Natural gas is delivered to pressure regulator valve from gas well christmas tree through gas well outlet line, enters in reheater and heat, then after pressure regulation
Enter in parallel pipeline, pipeline branch road and can drive the first order respectively through corresponding first order rotor dynamic machine release pressure
The axle of rotor dynamic machine rotates, and natural gas is entered reheater by pipeline after first order rotor dynamic machine is out and heats, heating
Rear entrance second level rotor dynamic machine drives the axle concentric with first order rotor dynamic machine to rotate again.Then two branch roads is natural
Gas imports in same pipeline, subsequently into follow-up operation.
There is a switch valve at the beginning having one in two parallel pipelines, and its purpose is to close, now when gas flow is less
Article one, generating pipeline just can carry out blood pressure lowering generating, if when flow is bigger, now opens switch valve and shunts natural gas.
Advantage of the present utility model and beneficial effect have: 1, distinguish conventional natural gas power system and sufficiently make use of natural gas
Pressure energy.2, generating device structure simple and durable.3, multilevel power generation system in parallel is used to have higher adaptation ability.4, energy
Produce bigger electric power and environmental protection.

Detailed description of the invention
Below in conjunction with the accompanying drawings the technical solution of the utility model is described specifically:
In FIG, this utility model utilizes the multistage three-apexed rotor electricity generation system of well head high-pressure natural gas pressure energy, mainly by gas
Well christmas tree 1, pressure regulator valve 2, reheater 3, three-apexed rotor engine 4, electromotor 7, switch valve 8 are with natural gas line even
Connect composition.Described gas well christmas tree 1 is connected with pressure regulator valve 2, and pressure regulator valve 2 connects reheater 3；The outlet of reheater 3 is in parallel
The multistage three-apexed rotor powerplant module that two-strip structure is identical；Wherein a multistage three-apexed rotor powerplant module turns at first order triangle
Having accessed reheater 5 in the middle of pipeline between sub-engine 4 and second level three-apexed rotor engine 6, first order three-apexed rotor moves
The concentric shafts of power machine 4 is connected with electromotor 7 by the axle of second level three-apexed rotor engine 6；Another multistage three-apexed rotor moves
Leading portion in power unit is connected to switch valve 8, and then switch valve 8 connects three-apexed rotor engine 9, then is linked in reheater 10,
It is linked into three-apexed rotor engine 11 the most again, is finally incorporated to be connected with pressure regulator valve 13 during supervisor converges, the multistage triangle of this pipeline
The concentric shafts of rotor dynamic machine is connected with electromotor 12 by the axle of three-apexed rotor engine 11.
Natural gas is transported to pressure regulator valve 2 from gas well christmas tree 1, by pressure regulator valve 3 pressure regulation, adds subsequently in reheater 3
Heat, is divided into two kinds of situations of height and operates to this, the first: under relatively low flow condition, closing switch valve 8, natural gas
Only enter in the pipeline of three-apexed rotor engine 4, thus discharge pressure energy for the first time and drive three-apexed rotor engine 4
Axle rotates, and then natural gas heats in entering reheater 5, enters in three-apexed rotor engine 6 and accelerate and triangle after heating
The axle rotation that rotor dynamic machine 4 is concentric, is finally incorporated to during supervisor converges enter subsequent technique after pressure regulator valve 13 pressure regulation；The second:
In the case of high flow, open fast valve 8, without the pipeline flow process of switch valve 8 with the most the same, natural on that pipeline
Gas is in fast valve 8 enters into the pipeline of three-apexed rotor engine 9, thus discharges pressure energy for the first time and drive triangle to turn
The axle of sub-engine 9 rotates, and then natural gas heats in entering reheater 10, enters three-apexed rotor engine after heating
Accelerating the axle concentric with three-apexed rotor engine 12 in 11 to rotate, entrance supervisor of finally confluxing together with that pipeline passes through in converging
Subsequent technique is entered after pressure regulation 13 pressure regulation.
