Fig. 1 is a kind of rough schematic view of pipeline gas gas transmission station.Gas transmission station comprises coming gas acceptance division 10 and multiple combustion gas departures portion 12.Come to be provided with combustion gas processing system 14 between gas acceptance division 10 and each combustion gas departures portion 12.Upstream is come after gas carries out various process by combustion gas processing system 14, by the combustion gas departures portion of correspondence to downstream gas transmission, such as, transports to other gas transmission branch line or other user.
As shown in Figure 1, upstream is carried out gas and is utilized many gas transmission circuits to distribute to downstream by gas transmission station.Every bar gas transmission circuit, except comprising the normal combustion gas processing system 14 used, also includes combustion gas processing system 16 for subsequent use.When the normal combustion gas processing system 14 used breaks down or need to overhaul, unlatching is come into operation by combustion gas processing system 16 for subsequent use.The position residing in the transmission of whole pipeline according to gas transmission station, combustion gas processing system 14 generally comprises separations, metering, heating, pressure regulation, blowdown, emptying, promptly blocks, pigging, the wherein part or all of subtense angle such as distribution.It is pointed out that separation, metering, blowdown, emptying, promptly block, pigging, gas distribution system etc. are not the emphasis will introduced herein, be not therefore further introduced herein.
Fig. 2 is the schematic diagram of the combustion gas processing system of a kind of pipeline gas transmission.This combustion gas processing system is arranged between gas acceptance division 10 and one of them combustion gas departures portion 12.As previously mentioned, the some of them subtense angle of combustion gas processing system, be such as separated, measure, blowdown, emptying, promptly block, pigging, gas distribution system, do not draw at this, be not discussed further yet.
This combustion gas processing system comprises turbo-expander 20.Turbo-expander 20 comprises fuel gas inlet 22 and gas outlet 24.Gas is carried out in the upstream that fuel gas inlet 22 receives gas pipeline for always gas acceptance division 10.Upstream is carried out gas and is expanded in turbo-expander 20 after step-down from gas outlet 24 downstream transport.
In order to meet the gaseous-pressure requirement of pipeline transmission, the pressure through the combustion gas of turbine expander step-down needs to maintain predetermined value.According to the diverse location of gas transmission station in whole pipeline transmission, predetermined value described herein is different.Such as, gaseous-pressure can be depressurized to 4MPa from 10Mpa, is depressurized to 2.5MPa or is depressurized to 1.6MPa from 2.5MPa from 4MPa, and can float within the specific limits.Should be understood that, at some gas transmission stations, the gaseous-pressure through pressure regulation can maintain other predetermined value.
In the embodiment of fig. 2, the maintenance of this predetermined gaseous-pressure utilizes the operation of turbo-expander self to realize.Specifically, namely turbo-expander comprises nozzle ring capable of changing cross sections 26(, stator blade) and turbine portion 28(is namely, movable vane).By adjusting the angle of nozzle blade, the flow area of above-mentioned nozzle ring capable of changing cross sections 26 can be changed, thus change the gaseous-pressure after pressure regulation.
The downstream position of gas outlet 24 is provided with pressure transducer 30, for detecting the pressure of the pipeline gas exported from gas outlet 24.The angle of self blade of pressure sensing result adjustment that nozzle ring capable of changing cross sections 26 detects according to pressure transducer 30, thus the gaseous-pressure after step-down of being expanded by turbo-expander 20 maintains predetermined value.
At some gas transmission stations, need to control the fuel gas temperature in pipeline.If temperature is too low, in combustion gas, hydrocarbon and water may form hydrate and blocking pipe equipment.Therefore, in the appropriate location of pipeline, heater 32 and temperature transducer 34 can be set, according to the temperature detection result that temperature transducer 34 detects, pipeline and interior combustion gas thereof be heated, fuel gas temperature be maintained be suitable for the predetermined value transmitted.This predetermined value is a temperature range, can determine or relevant specification specifies according to actual conditions.
In one embodiment, above-mentioned voltage-regulating system also comprises the generator 36 be connected with turbo-expander 20.Wherein, when pipeline gas flow through turbo-expander 20 drive described turbo-expander 20 to rotate time, described turbo-expander 20 drives generator 36 to generate electricity.The electric power that generator 36 produces can supply the equipment use in gas transmission station, such as can as the energy of above-mentioned heater 32.In a specific embodiment, above-mentioned heater 32 can be electric heater.In another embodiment, also can be with electric-heating water, then carry out the combustion gas in heating pipe with hot water.
