The present invention proposes a kind of method and apparatus that utilizes steam to produce power, wherein according to the present invention, these power plant comprise having from steam source simultaneously to the mechanism of the power plant combining unit delivering vapor of many combinations, and each unit has one by steam driven and produce the steam turbine of waste hot steam; One is connected with steam turbine, and its operating pressure preferably is not less than the condenser of atmospheric pressure, and it is used for collecting uncondensable gas and is input to the systematic working medium of condenser and condensation waste heat steam by vaporization; The rankine cycle turbine of a closed system of moving with systematic working medium; One continuous by steam turbine and the turbine-driven preferably single generator that is used to generate electricity of rankine cycle.Be used for steam is preferably included a control valve that is connected with each power plant unit from steam source to the mechanism that each power plant combining unit is carried.The present invention even also go for an above-mentioned power plant combining unit.And then each power plant combining unit comprises a systematic working medium condenser that is used for this systematic working medium of condensation, and this condenser is preferably air cooled; With a mechanism that is used for making the systematic working medium that is condensed to turn back to the vaporizer of the system that is positioned at stram condenser inside.And perhaps a mechanism that is used for compressing the incondensable gas that the stram condenser that is positioned at each described power plant unit inside exists is provided, compressed uncondensable gas is discharged in the recovery well with the steam condensate that is pressurized that produces in stram condenser.
Consider that the present invention is suitable for relying on available steam operation in geothermal vapour and other thermal source such as the industrial flow, the working medium of the rankine cycle turbine of the closed system in power plant unit is pentane preferably.
Because in the present invention, thermal source steam is assigned to each power plant combining unit with the pressure of steam source itself basically, thereby the diameter of distribution duct is less relatively, and the size of control valve is also little as a result, has reduced the expense of the said equipment so in fact.In addition, because each power plant unit has all comprised a steam turbine, the rankine cycle turbine of a closed system and independent generator preferably.Therefore the present invention has improved Economy, has simplified the control of operation, and has improved efficient.
Embodiment of the present invention are described below by embodiment and with reference to accompanying drawing:
Fig. 1: be the ground thermodynamic device of prior art;
Fig. 2: be principle schematic according to ground of the present invention thermodynamic device;
Fig. 3: be one embodiment of the present of invention schematic representation.
Referring now to accompanying drawing, parameter 10 one of expression are used for the general ground thermodynamic device of geothermal vapour generating among Fig. 1, wherein come the steam in the artesian well 11 to flow to steam turbine 15 through conduit 12 and control valve 13.Turbine obtains energy and drives generator 18 from steam, it utilizes control system 14 that electricity is transported to electrical network through electric power protection subtense angle 17.Usually, electric power protection subtense angle 17 includes circuit breaker and other protection mechanisms, also adopts power distribution unit.Steam discharge distribution duct 19a, 19b and 19c utilize control valve 22a, 22b, 22c is to stram condenser 27a, and 27b and 27c import the waste hot steam that steam turbine 15 is discharged, control valve 22a, 22b and 22c are by the rankine cycle that is positioned at closed system (ORC) power plant unit 20a, 20b, the control mechanism 25a of 20c inside, 25b and 25c control respectively.Because be used for the steam of power plant unit is the waste hot steam that steam turbine 15 is discharged, so its pressure is relatively low, is generally 25 pounds/inch
2, therefore, pipeline 19a, 19b, the diameter of 19c is relatively large, for example about 140cm, and its valve 22a that has, 22b and 22c have bigger size, and the cost of making the said equipment is quite high.Stram condenser 27a, 27b, 27c is preferably in to be higher than under the atmospheric pressure situation and moves, from this system, extract the uncondensable gas that is present in the steam so that help compressed machine 26, then utilize pump 42 to be transported in the recovery well 45 through delivery pipe by condensation product and the compressed gas that stram condenser produces.Coiler 28a, 28b, 28c are positioned at the stram condenser of system fluid 27a, is used for cooler condenser among 27b and the 27c.Condenser is also as the vaporizer of the systematic working medium of the rankine cycle power plant unit of system.At coiler 28a, 28b, the system fluid that is vaporized among the 28c is transported to steam turbine 30a, and 30b and 30c to be driving generator 35a, and 35b and 35c transport to electrical network by power distribution unit and electric power protection subtense angle 34a, 34b and 34c with electricity.The systematic working medium steam of being discharged by turbine 30a, 30b and 30c is transported to systematic working medium condenser 36a, 36b and 36c, and be condensed therein, the system fluid that is condensed turns back under the effect of pump 38a, 38b and 38c among vaporizer coiler 28a, 28b and the 28c, has finished the circulation of system fluid like this.The cooling water that is arranged in cooling water device (not shown) can be used to cool off these condensers, and perhaps the air of preferably being carried by forced draught air-cooling apparatus (not expressing) is used to cool off these condensers.
Be used for controlling unit control system 25a, the 25b of the waste hot steam amount of transporting to power plant unit 20a, 20b, 20c and 25c according to monitor the power that produced by generator 35a, 35b and 35c and (or) pressure of vaporization coiler 28a, 28b and 28c, adjust the aperture of control valve 22a, 22b and 22c.In addition, these control system thermal source steam flow of transporting to steam turbine 15 by 13 pairs of control valves is controlled.If it is less so for example to transport to the electric power of electrical network, control system transmit a signal to control valve 22a, 22b and 22c to reduce their aperture, make the waste hot steam quantitative change of transporting to stram condenser 27a, 27b and 27c little, the pressure in the vaporizer coiler is diminished.As a result, steam turbine 30a, the 30b of system, 30c and the output of the generator that is connected with them reduce.In this case, also can suitably reduce the thermal source steam flow that is transported to steam turbine 15, thereby reduce its operating pressure and therefore reduced the output of steam turbine by the aperture of adjusting control valve 13.This is owing to the cooling medium of the systematic working medium in the rankine cycle turbine unit that is included in each system as the stram condenser of steam turbine 15.And, if one of rankine cycle power plant of system breaks down as 20a and will be closed, control system 25a is with closed control valve 22a so, valve 13 produces corresponding the adjustment as a result, the thermal source steam flow that is transported to steam turbine 15 is changed, also make this turbine depart from its rated pressure, under the lower situation of efficient, move.
In Fig. 2, numeral 50 expressions are according to the device that produces power with steam of the present invention, wherein distribution duct 51A is used for being transported to simultaneously from the geothermal vapour that well 51 is discharged the steam turbine the power plant combining unit of many combinations, wherein shows three unit 55a, 55b and 55c.Yet the present invention also goes for a power plant unit.Separator 53 be used for the geothermal fluid of heat with separate from being included in the steam of discharging geothermal fluids by well 51, and exsiccator 52 can be used for guaranteeing the humidity minimum in the steam.Usually, the vapor pressure of thermal source is about 150 pounds/inch
2Here for convenience, we relate to power plant combining unit 55a, and it includes steam control valve 57a and steam turbine 60a, so that receive thermal source steam, and steam expands a process axle 61a driving generator 65a work done in turbine 60a.The operation of valve 57a is controlled by control system 56a.Stram condenser 62a is preferably in to be higher than under the atmospheric pressure and moves so that impel the uncondensable gas separation that is included in the steam.By using the system fluid cooling steam among the coiler 67a that is input to condenser inside, the waste hot steam that stram condenser 62a condensation is discharged from steam turbine 60a.Above-mentioned this scheme needn't adopt vacuum pump.Compressor 59 is used for compressing the uncondensable gas that is present in stram condenser 62a.Compressed gas flows into and puts in place in the exhaust duct 79 in valve 77 downstreams, is piped in the recovery well 80 with condenser condensation product that produce and that discharge from suction booster 76a there.Coiler 67a is also as the vaporizer of the turbine of the rankine cycle of closed system.The working medium of system is vaporized in coiler.The FLUID TRANSPORTATION that is vaporized also expands in the steam turbine 70a of system therein, preferably also drives generator 65a by axle 68a and produces useful work.The example of the rankine cycle turbine of an available closed system is by U.S. Pat 3,409, and 782 is disclosed, and its disclosed content is used as reference here.Adopt preheater 71a, so that the geothermal fluid that makes the heat of discharging from separator 53 is through suction booster 54A, before it is input to coiler 67a, systematic working medium is carried out preheating, the useless geothermal fluid of discharging from preheater 71a preferably flows to valve 77 through pipeline 78, is drained into well 80 so that reclaim through discharge conduit 79.Valve 77 helps to keep in the pipeline 54 and connects in the pipeline between preheater 71a and the pump 54A and connect in the pipeline that preheater exports to be in relative high pressure, and the steam flashing that appears at these ducted brine stream is excluded basically.Preferably utilize pentane as systematic working medium.Yet other system fluid such as dichlorodifluoromethan etc. also can use.Preferably the capacity of generator 65a is greater than the capacity of steam turbine 60a and the turbine 70a of system.The generate output that it produced preferably equals the summation of steam turbine 60a and the steam turbine 70a of system capacity.For example the capacity of steam turbine 60a can be that 1.5MW and the capacity that has the steam turbine 70a of system also are 1.5MW, and the capacity of generator 65a is 3MW so, allows the oepration at full load simultaneously of water vapor turbine and steam turbine like this.Although do not express, preferably be installed in clutch on axle 61a and the 68a between generator and water vapor turbine and the steam turbine and have separately generator.System fluid condenser 72a is used for system's steam that condensation is discharged by steam turbine 70a, and this condenser provides air cooling by the powerful air ventilation plant or the most handyly by corresponding device thereof cooling water is transported to condenser and cools off.Pump 74a makes the system fluid that is condensed turn back to coiler 67a, has finished the circulation of fluid of system like this.Thereby power plant 50 are a kind of like this mixed power plants, and it comprises a part and the part with the system fluid operation with the geothermal vapour operation.
Like this, as can be seen from Figure 2, when device 50 operations, the steam that comes artesian well 51 is after separator 53 and exsiccator 52 discharges, by action, be assigned to each power plant combining unit through pipeline 51A by control system 56a, 56b and 56c control steam control valve 57a, 57b and 57c.Because steam is to be equivalent to thermal source vapor pressure in the well 51 rather than to be assigned to the power plant combining unit with the low relatively steam turbine exhaust pressure of general employing shown in Figure 1, so the diameter of distribution duct is less relatively, for example working as working pressure is 150 pounds/inch
2The time, diameter is about 50cm.And owing to this reason, the size of control valve 57a, 57b and 57c is also relative less, has obtained sizable saving like this.Be transported to the steam expansion work done of steam turbine 60a, 60b and 60c, drive generator 65a, 65b and 65c generates electricity by axle 61a, 61b and 61c.The waste hot steam that turbine 60a, 60b and 60c discharge is transported among stram condenser 62a, 62b and the 62c, and condensation therein, the condensation product that is collected in stram condenser utilizes suction booster 76a, 76b and 76c to be transported in the well 80 through pipeline 75, and compressed machine 59 compressions of the uncondensable gas that is collected in stram condenser are transported in the well 80.Systematic working medium is vaporized among coiler 67a, 67b and 67c by the liquid heating back of the heat of discharging from separator 53 in preheater 71a, 71b and 71c; this working medium is transported to steam turbine 70a, 70b and 70c; and expand therein; turbine is rotated; drive generator 65a, 65b and 65c generating, deliver power to electrical network by protection loop and corresponding power distribution unit.System's steam turbine 70a, 70b and 70c contribute to the generated energy of generator 65a, 65b and 65c like this.Shared generator and electrical apparatus element such as shared power distribution unit have improved the Economy of system and have been convenient to operation.The waste hot steam of being discharged by turbine 70a, 70b and 70c is transported to system fluid condenser 72a, 72b and 72c, and is condensed therein, and the condensation product that is generated utilizes pump 74a, 74b and 74c to be transported among vaporizer coiler 67a, 67b and the 67c respectively.The geothermal fluid of discharging from preheater 71a, 71b and 71c utilizes mixing arrangement mixed with the condensation product of discharging from suction booster 76a, 76b and 76c, is input to recovery well 80 through valve 77 again.
In the embodiment shown in Figure 2, control system 56a, 56b and 56c utilize steam control valve 57a, 57b and 57c correspondingly to control the size that the steam flow that is transported to the power plant combining unit is controlled each unit generated energy by monitoring generator 65a, 65b and the generating strength of 65c and the pressure among vaporizer coiler 67a, 67b and the 67c.For example when normal operation,, the thermal source steam that is transported to a power plant unit such as 55a is reduced by the control valve of suitably regulating it if the control system indication will be carried less current to electrical network.Make this unit to the less power of electrical network output, and allow other power plant unit to continue operation, to keep their efficient with their declared working condition.Like this, in this case, in unit 55a, control system 56a reduces the aperture of control valve 57a, allow more a spot of thermal source delivery of steam to steam turbine 60a, then stram condenser 62a diminishes the operating pressure among the vaporization coiler 67a, cause that steam turbine 70a and water vapor turbine 60a institute work reduce, and then the power that generator 65a is sent descends accordingly.And if owing to reasons such as accident or maintenances, one of this combining unit can not move, and do not move the control system of unit and will close its control valve simply, and other unit continues operation with its declared working condition.As a result, being positioned at water vapor turbine among other combining units is in operation and can keeps higher efficient.This is opposite with general power plant example as shown in fig. 1, in this device, among closing unit 20a, 20b and the 20c one, the reducing of steam flow that also will cause being transported to the steam turbine 15 among Fig. 1 by part steam off valve 13, make the operating pressure of steam turbine depart from its rating value, the result makes its decrease in efficiency.And in the present invention, owing to comprised the steam turbine of combining with the rankine cycle turbine of closed system and be preferably in that an independent generator is arranged in each power plant unit, it is higher to have obtained an operational efficiency, Economy is improved, and control system simply produces power plant.Wherein each unit has only a steam control valve, and it has eliminated the rankine cycle turbine that resembles steam turbine of the prior art and system needs independent control valve.And a steam turbine and a closed system rankine cycle turbine are combined into a power plant unit, make that the manufacturing of this device unit and maintenance are all more convenient.For example the present invention has saved the big supporting structure that the steam turbine manufacturing is installed in the prior art.In addition, be preferably among the special embodiment, pump 74a, 74b and 74c also can be installed on the common axle with steam turbine and system's turbine, start automatically with the rankine cycle turbine that allows system.Preferably in the present invention, the unit is in the hot stand-by duty of oriented accessory transmission of electric energy, so that when needing, it can be connected at once with electrical network.
In this scheme, condensation product is mixed with geothermal fluid mutually with a spot of uncondensable gas, be input in the recovery well 80 with pipeline, the salt solution inorganic matter sediment yield in the pipeline that leads to recovery well and in the well itself is reduced.This mainly is because the pH value of condensation product is low as 3-5.This effect be of value to reduce each pipeline each other go into the pollution of the sludge (mainly being silica) in the relevant parts of recovery well with jet fluid.Though the salt solution of discharging from separator 53 in this programme is used to the system fluid the rankine cycle turbine of pre-heating system, but salt solution can directly enter recovery well and not preheating has the system fluid of condensation product and incondensable gas, also can reduce above-mentioned inorganic matter deposition with this.In addition, although have separator and exsiccator in this programme, the present invention is also applicable to some places, and the character of underground heat and steam does not need this kind equipment there.
Although this programme belongs to the utilization of geothermal vapour, the present invention also goes for other thermal source such as industrial fluids and steam, sunshine pond and from used heat in the industrial flow such as flue gas.An intermediate heat exchanger can be installed if desired, and the steam that will pass through to be generated from the heat that thermal source obtained is delivered to the power plant combining unit.An embodiment of above-mentioned application as shown in Figure 3, wherein from including the hot flue gas form of thermal source 107() steam source 105 produce steam, pressurized water loop 106 has pump 108 and is used to generate the flash chamber 110 of steam.The power plant combining unit 115 that is combined includes the rankine cycle turbine 130 of steam turbine 120 and closed system, remove outside the mechanism that is not used in the processing incondensable gas (common this gas is non-existent), unit combination is moved to be substantially similar to reference to the mode of one of described unit of Fig. 2.Stram condenser 122 also is preferably under the situation that is not less than atmospheric pressure and works.Suction booster 119 is used to increase the pressure of condensation product of the liquid water of exhaust steam condenser 122, and makes it flow into pressurized water loop 106.Preferably suction booster 119 can be a jet pump, and it utilizes the high pressure of flowing liquid in the pressurized water loop.The power plant unit of combination and the steam source use in conjunction of the so-called press water heat exchanger shown in Fig. 3, higher mainly due to the steam of discharging flash chamber 110 outlets with the temperature of the steam that enters into steam turbine 120, the higher and very economical of efficient when making by the thermal power transfer electric energy.In addition, in this programme, avoided the employing superheater.In addition, adopted system fluid in having the part power plant of the above-mentioned type thermal source, because their thermodynamic properties, it has tangible advantage, and for example they have low relatively boiling point.When adopting suitable system fluid, resulting steam moisture minimum when in steam turbine, expanding, and high relatively preheat value (that is: is brought up to the needed heat of vapourizing temperature of liquid form with system works liquid from the temperature of condenser in the time per unit, with the ratio of the required total amount of heat of vaporization working medium in the time per unit.）。Ban use of the place of containing the combustible substance device at some, adopt advantageous particularly of the present invention.In these cases, the steam turbine of combining unit part can be installed in prohibits scene of a fire institute, in above-mentioned place even allow generating.
