Description
Technical field
The utility model belongs to fuel gas transmission and technical field of power generation, and in particular to a kind of natural gas wellhead pressure energy power generation
Throttle system.
Background technique
For natural gas in collection process, natural gas has elevated pressures and very high humidity, in order to reduce investment outlay and give birth to safely
It produces, needs to carry out reducing pressure by regulating flow to underground natural gas, then carry out the production processes such as surface gathering and transferring, pretreatment again.Natural gas from
Gas well extraction after, when flowing through restricting element, natural gas due to throttling act on, volume expansion, pressure reduction, temperature sharply under
Drop results in gas hydrates or condensation water freezing is made to block pipeline；Meanwhile too low temperature will also result in pipeline material
Expect that cold brittleness increases, brings security risk.To prevent above-mentioned unfavorable phenomenon, the well site natural gas collection generallyd use both at home and abroad at present
There are two types of defeated process flows:
(1) in well head using heating furnace (combustion parts natural gas) come heated natural gas.If well head is that high sulfur-bearing is natural
Gas, then cannot directly burn this well head natural gas, need to draw natural gas outside other pipe laying, construction cost is quite high.
(2) spray anti-freeze inhibitors (such as methanol) into natural gas.This method not can be reduced too low temperature to pipeline
Cold brittleness security risk caused by material.
In addition to this, it is gentle to be concentrated mainly on the pressure loss of energy during gas throttling for the energy consumption of both techniques
Thermal energy consumption in body heating process, particularly with room temperature separating technology, the natural gas after heating must reach 60 DEG C of left sides
It is right just to can enter separator.If the pressure energy lost in throttling process can make full use of, while saving and additionally consuming
Thermal energy then not only can produce huge economic benefit, but also can eliminate environmental pollution caused by combustion of natural gas.
Utility model content
In view of this, the utility model aim is to provide a kind of throttle system of natural gas wellhead pressure energy power generation, make it
The pressure energy lost in throttling process can be made full use of, the thermal energy additionally consumed is saved, reduces cost and security risk.
To achieve the goals above, the utility model is realized by the following technical solutions: a kind of natural gas wellhead pressure
The throttle system that power can generate electricity, including expansion unit, air cooler and generator, the expansion unit is by least three-level expanding machine string
Connection forms and is arranged with the generator coaxle, the inlet end and an air inlet pipe of the first order expanding machine in the expansion unit
Connection, exhaust end by the connection of air cooler described in one first delivery pipe, afterbody expanding machine in the expansion unit into
Position of the gas end by the way that one second delivery pipe is connect with the air cooler, exhaust end is connect with an exhaust pipe, in the expansion unit
The inlet end of other expanding machines between the first order expanding machine and afterbody expanding machine passes through second delivery pipe
It is connect with the air cooler, exhaust end is connect by first delivery pipe with the air cooler, second delivery pipe and institute
It states and is designed with electric heater unit on exhaust pipe, the electric heater unit and the power generation mechatronics.
Further, the electric heater unit is heating tape.
The utility model has the beneficial effects that the throttle system of natural gas wellhead pressure energy power generation provided by the utility model,
Since the electric energy of heating tape is provided by generator, the electric power of the sending of generator is produced by natural gas in expansion unit decompression acting
It is raw.Therefore, the pressure energy that throttle system provided by the utility model can make full use of natural gas to lose in throttling process, section
The thermal energy about additionally consumed achievees the purpose that reduce cost and security risk.
Detailed description of the invention
Fig. 1 is the work flow diagram of the utility model.
Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figure 1, the utility model provides a kind of throttle system of natural gas wellhead pressure energy power generation, including expanding machine
Group, air cooler 8, generator 6, air inlet pipe 1, exhaust pipe, the first delivery pipe 7, the second delivery pipe 9 and heating device.
Expansion unit is connected in series by least three-level expanding machine and is coaxially disposed with generator 6, in the present embodiment, preferably
The series for expanding unit is level Four.The inlet end of first order expanding machine 2 connect with air inlet pipe 1, exhaust end is first defeated by one
Pipe 7 is sent to connect with air cooler 8.The inlet end of second level expanding machine 3 is connect with air cooler 8, is vented by second delivery pipe 9
End is connect by first delivery pipe 7 with air cooler 8, and the setting of third level expanding machine 4 is identical as second level expanding machine 3, the
The inlet end of quadruple expansion engine 5 is connect by second delivery pipe 9 with air cooler 8, exhaust end and exhaust pipe connect.Every
Electric heater unit is all set in two delivery pipes 9 and on exhaust pipe, which connect with generator 6.It is preferred that electric heating
Device is heating tape 10, and heating tape 10 is directly wound on the second delivery pipe 9 and exhaust pipe.
Working principle: the high-pressure natural gas come out by import is entered the first order expanding machine in expansion unit by air inlet pipe 1
2, first step decompression is carried out, the temperature of decompression is controlled at -5 DEG C or so.From first order expanding machine 2 come out after cryogenic natural gas warp
First delivery pipe 7 is sent to air cooler 8, utilizes atmospheric heat heated natural gas.Natural gas after being heated by air cooler 8, through the
Two delivery pipes 9 are sent in second level expanding machine 3, and natural gas is heated the heating of band 10 during passing through the second delivery pipe 9.With
This analogizes, and final natural gas is discharged after being heated to suitable temperature from exhaust pipe.
