Technical field
Fire, the distributed heat-electricity-cold combined supply coal poly-generation of nuclear power generation cogeneration of heat and power.
Background technology
(1), foreword:
The guiding of energy power system research depends primarily on trend that world energy sources development changes with structure and the development that energy science itself is studied.Its research can be divided into for 3 generations: the research of the first generation, based on the first law of thermodynamics, generally tries to achieve the higher thermal efficiency by raising cycling hot force parameter and parts internal efficiency; The feature of the second generation is based on second law, and the grade difference focusing on energy organically combines from cascade utilization and different circulation, proposes supply system; Conception of Sustainable Development is given prominence in the research of the third generation, focuses on supply system and efficient clean utilization, optimizes economic effect and to be combined and energy and environment are comprehensively permeated.
There are four large disadvantages in conventional fossil energy dynamical system: the heavy losses of combustion process fuel grade, the tomography that high temperature section thermal power transfer utilizes, a large amount of middle low temperature heat energy emission loss of low-temperature zone and to ecological environment severe contamination.For this reason, people constantly propose that power conversion utilizes new ideas, the new mechanism of Engineering Thermophysics process, thermodynamic cycle is newly conceived and energy source and power New Development Pattern, the study hotspot that constantly developing is new in traditional energy scientific basic.They normally improve energy resources utilization rate and the key of improving the ecological environment and breach, are intended to set up revolutionary energy power system.A new generation's energy power system is a more complicated system, its research object is the complexity science of physical level, except more furtheing investigate common problem (system simulation and complex optimum, the system integration, function and characteristic, the regulation and control of system multi-objective evaluation criterion and system with prepare) outward, at present based on different developing goals, main direction of studying has: 1. thermodynamic cycle innovation and power conversion utilize new mechanism; 2. multi-functional energy power system; 3. the utilization system of multiple-energy-source; 4. non-harmful energy power system; 5. middle low-temperature energy sources conversion system etc.
Thermodynamic cycle is the theoretical foundation of dynamical system development.For many years, the improvement of various thermodynamic cycle is all follow to improve constantly on the one hand the maximum temperature of circulation with the ratio of minimum temperature with improve component capabilities in principle; On the other hand actual cycle is carried out as far as possible close to the direction of desirable Carnot cycle.
At present, people carried out analyzing in detail to nearly all simple cycle, there has been comprehensive grasp to the characteristic of these simple cycle.Present people start sight is turned to how to build new circulation, and improve in its thermodynamic property as far as possible.In energy and power engineering field, realized the output of mechanical energy by thermodynamic cycle, the research around thermodynamic cycle is the permanent problem of using energy source conversion art, high efficiency of energy, the clean pioneering basic research developing the corresponding thermodynamic cycle of needs.
(2), capillary pump loop heat pipe (CPL):
Capillary pump loop heat pipe (CPL) forms primarily of with lower part: evaporimeter, condenser, steam channel, fluid passage reservoir, isolator and control system (heater and temperature sensor).The schematic diagram of capillary pump loop is as Fig. 1. shown in.
Hydraulic fluid absorbs heat and carburation by evaporation from thermal source in evaporimeter, the steam produced enters condenser through steam channel, steam is released heat and condenses into liquid in condenser, the capillary force that liquid provides due to capillary structure and get back to evaporimeter through fluid passage.Circulation like this, heat is constantly transmitted to condenser from evaporimeter with the form of phase-change heat transfer by the working medium in loop.Isolator is arranged on the porch that fluid pipeline enters evaporimeter, and the incondensable gas carried of fluid passage and vapor bubbles are collected in its effect, prevents them from entering the capillary wick of evaporimeter and blocking fluid flow.Reservoir is applicable to restarting of any situation in the startup of temperature adjusting and evaporimeter and running.CPL is as thermal control element, and it has following features:
(1) CPL has higher heat-transfer capability and isothermal.Due in CPL loop, the passage of steam and liquid is distinct, so there is not the entrainment limit in general heat pipe.Except evaporimeter, remainder can adopt smooth tube, this reduces the pressure loss of system, thus makes the heat-transfer capability of CPL higher than general heat pipe.In CPL loop, the phase transition process of fluid almost completes under isothermal, and therefore, the isothermal of CPL system is very good.The pressure loss in CPL loop is little, makes CPL system can realize long distance heat transfer.
(2) CPL has excellent temperature control characteristic.CPL can utilize control system the operating temperature in loop to be regulated and controled in required temperature range.Reservoir is connected with CPL loop, and therefore the two has identical operating pressure, by carrying out the operating pressure of regulating system to the heating of reservoir or condensation, thus regulates the heat exchange area of condenser to reach the operate in saturation temperature of control system.
(3) heat shares characteristic.The evaporimeter of CPL can be formed in parallel by multiple evaporimeter, the thermic load of each evaporimeter can be very different, even if some evaporimeters do not have load, due to the swabbing action of pressure balance in system and each evaporimeter, it also can share the load of all the other evaporimeters, makes system temperature consistent.
(4) pressure injection characteristic.Once indivedual evaporimeter occurs drying up because thermic load surprisingly overloads, in the continuation of system runs, by heating reservoir, pressure injection can be carried out and the evaporimeter dried up resumed work.
(5) thermal diode characteristic.Do not have capillary structure in condenser, therefore heat can only be transmitted to condenser from evaporimeter, from then on serves the effect of thermal diode.
Add the thermal conductivity factor that nano particle significantly improves liquid in a liquid, its reason may have following two aspects: cupric oxide-water nano-fluid.
A), because the thermal conductivity factor of solid particle is far longer than the thermal conductivity factor of liquid.Solid particle add the structure changing liquid, enhance the energy transfer process of mixture inside, the thermal conductivity factor of liquid increased.Thermal Conductivity of Nanofluids increases along with the increase of nano particle volume integral number.The volume fraction of nano particle is larger, and in unit volume, the nano particle of liquid dispersion is more, causes the microconvection of the heat transfer of nano particle and nano particle, nano particle and liquid to strengthen, and energy transferring is accelerated, and thermal conductivity increases; The thermal conductivity factor of nano-fluid is relevant with the thermal conductivity factor of the material forming nano particle, and the thermal conductivity factor forming the material of nano particle is larger, and the thermal conductivity factor of nano-fluid is also larger.
B), due to the small-size effect of nano particle, the nano particle suspended in nano-fluid is by the effect of brown force, do random motion, the phenomenons such as Blang's diffusion, thermal diffusion are present in nano-fluid, the micromotion of nano particle makes have microconvection phenomenon to exist between nano particle and liquid, this microconvection enhances the energy transfer process between nano particle and liquid, increases the thermal conductivity factor of nano-fluid.The most important thing is, the nano particle suspended in nano-fluid is while doing random motion, energy entrained by himself also there occurs migration, compared with microconvection reinforced heat conduction coefficient between nano particle with liquid, this part energy transfer that nanoparticle movement produces greatly strengthen nano-fluid internal energy transmittance process, larger to the effect of nano-fluid reinforced heat conduction coefficient.Nanoparticle size is less, and Thermal Conductivities of Nanofluids is larger.This is because the internal heat transfer of nano-fluid occurs in the surface of liquid and nano particle, surface area is larger, and heat transfer is just more effectively with rapid, and namely particle specific surface area is more conducive to heat transfer more greatly.When nanoparticle size reduces time, specific area can increase with the speed of 103 times, and therefore the reduction of nanoparticle size will directly cause the raising of thermal conductivity.Meanwhile, the temperature of nano-fluid is higher, and the thermal conductivity factor of nano-fluid is larger.Because along with the raising of nano-fluid suspension temperature, main medium is transmitted as nano-fluid internal energy--the intensity aggravation of nano particle micromotion, nano particle and nano particle, the frequency of colliding between nano particle and liquid strengthen, the speed of energy transferring is accelerated, and the ability of nano-fluid reinforced heat conduction coefficient is strengthened.
Can improve heat exchange property and the critical heat flux density of evaporator section at Experimental Study On Thermosiphonby Adding Nanoparticles To Working Fluid, the coefficient of heat transfer of condensation segment does not change; Heat pipe operating pressure is lower, and the effect of nano particle opposite heat tube enhanced heat transfer is more remarkable, and maximum 160% critical heat flux density that improves of the coefficient of heat transfer of heat pipe improves 120%; There is a best nanoparticle mass concentration, under this concentration, the coefficient of heat transfer of heat pipe evaporator section is the highest.
(3), fire, nuclear power plant's prior art state:
Fire, nuclear power plant's steam turbine have condensing-type (containing steam extraction and condensing formula) and back pressure type two kinds, and except the multiplex back pressure type of thermal power plant unit of steam power plant, most non-Steam Turbine for steam power plant is condensing-type machine.In China's fire, nuclear power plant's installation general power, nearly 86% is non-heat supply type.Cold junction must be there is, the some position that namely in Steam Power Circulation, steam temperature is minimum in the thermodynamic cycle that steam turbine utilizes high temperature and high pressure steam to do work.To condensing-type unit, steam, after the whole impeller acting of steam turbine, becomes exhaust steam, drains into exhaust casing, enter steam turbine cold junction--condenser.In this contactless cooler of condenser, exhaust steam heat transfer, to recirculated cooling water, after discharging its latent heat of condensation, becomes condensate water and is returned to boiler.What ensure steam turbine cold junction effect is flow through the recirculated cooling water that condenser absorbs the exhaust steam latent heat of condensation.Cooling water has two sources: one is take from natural water area; Two is the cooling towers from power plant.Generating set is not out of service, recirculated cooling water (warm water discharge) then a moment ceaselessly by a large amount of Decay heat removal to environment.Compose the waste heat amount of depositing in circulating cooling water of power plant very huge, abandon hot inevitable to heat engine production process.Steam (steam discharge) condensation (heat release) after steam turbine work done becomes condensate water after backheat, to enter boiler again, steam work done in steam turbine that boiler produces, and in the cyclic process of this heating agent, needs to release a large amount of condensation heat.The main feature of condensation heat is as follows:
Grade is low.Exhaust steam pressure: water-cooled, 4-8kPa; Air cooling, 15kPa.Condensation temperature: water-cooled, 29-41.5 DEG C; Air cooling, 54 DEG C.
Amount is large, concentrated.Average generating heat dissipation accounts for about 32% of total input.The recyclable condensation heat that pure condensed steam operating mode enters air accounts for more than 50%, is more than 1.5 times of the heat dissipation that generates electricity; The 0.7-1.3 of generating heat dissipation is about doubly for the recyclable condensation heat of thermal condition.
Power plant's heat exhaust is huge directly related with its heat engine production efficiency.General large thermal power plant BTHE is only 40%, and nuclear power is not as good as 35%, and more than 60% heat is discharged to environment (mainly cooling water is taken away).For 1000MW thermal power steam turbine group, the circulating cooling water yield about 35 ~ 45m3/s (3 × 106 ~ 4 × 106m3/d), draining temperature rise (namely exceeding the temperature in environment waters) 8 ~ 13 DEG C (becoming depending on season), this temperature rise compose heat about 1.2 × 106 ~ 1.9 × 106kJ/s deposited; Run 5000h meter per year, average annual 3.0 ~ 4.8 × 1013kJ/a, its heat amounts to standard coal about 70 ~ 1,140,000 t/a.The warm water discharge temperature of discharging, winter 20 ~ 35 DEG C; Summer 25 ~ 45 DEG C (different depending on power plant their location).Nuclear power generating sets quantity of circulating water is 1.2 ~ 1.5 times of fired power generating unit, and abandoning heat can be more.National thermoelectricity installation total amount about 7.9 hundred million kilowatts in 2010, accounts for thermoelectricity total capacity 86% by non-thermal power plant unit capacity and roughly estimates, about have the suitable whole year 8.4 hundred million tons of standard coals to throw away in vain in environment.Thermal power plant every loss reference value subordinate list 1.
(4), injection supercharging:
Injector supercharging is the high-energy fluid utilizing one pressure higher, makes the device that another strand of low energy fluid pressure is improved.Because structure is simple, be connected easily with miscellaneous equipment, maintenance management is convenient and become a kind of important device in a lot of field already, and is the focus of research always.Jet theory perfect further in recent years, and has widened range of application.But, conventional injector supercharging still can not meet the instructions for use in each field, the development of military equipment as important in some, the recovery (lighter hydrocarbons recovery) etc. of the crude oil gas of oil field enormous amount, existing ejectors technique will be applied to these fields, there are two fatal deficiencies: one be system inlet pressure loss bigger than normal, cannot special requirement be met; Two is that multilevel system all must from inter-stage carrying-off certain media, and requires not to be inconsistent.Therefore using for meeting, managing that the inlet pressure of injector pressure charging system is lost enough little, simultaneously again not from its inter-stage carrying-off certain media, just having become two key issues of necessary solution.
Summary of the invention
The heat that waste heat (condensation heat) in fire, nuclear power plant's recirculated cooling water cooling procedure discharges is huge, the negative heat affecting of its discharge environment; Propose and adopt heat absorption type heat pump, loop heat pipe, key technical problem that injection supercharging, ejection circulation systems technology solve recycling waste heat of condensation.Figure (3) is in new century harmonious power construction process, and circulating cooling water of power plant condensation heat efficiency utilization has just been complied with and accelerated to advance the construction of environmental protection cleaner power sources, and power plant construction is become environmentally friendly and this requirement of resource-conserving industry.
Accompanying drawing explanation
Figure (1) capillary pump loop heat pipe (CPL) forms primarily of with lower part: evaporimeter, condenser, steam channel, fluid passage reservoir, isolator and control system (heater and temperature sensor).
Figure (2) CPL has excellent temperature control characteristic.CPL can utilize control system the operating temperature in loop to be regulated and controled in required temperature range.
Figure (3) is overall system view, 4. 1. steam enter steam turbine, enters gas extraction system and 5. then enter absorption type heat pump system and 7. reach normal temperature state 15-25 DEG C and after circulating pump (11) enters deoxygenation, enter therrmodynamic system recycle and form previous stage Rakin system after generating.By bleed 2. with waste hot gas 3. and steam one tunnel of the joint group main steam that becomes injection pressurization cycle be increased to 3-5MPa through two-step supercharging or three grades of superchargings and enter hot water generator by separately leading up to the pressure of 150 DEG C of hot water of loop heat pipe and 8. generate electricity.Can obtain after hot water generating 80 DEG C of water, 50 DEG C of circulating pumps after heat supply 10. arrive sorption type heat pump (12), 7. the heat absorption of the heat of condensation heat through loop heat pipe 6. post bake to 92 DEG C, then be increased to 3-5MPa through the pressure that injection pressurization cycle two-step supercharging 9. or three grades are pressurized to 150 DEG C of hot water and enter hot water generator and 8. to generate electricity and 9. heat supply is injection type back pressure circulating pump.(12) combination cooling loop technology.This combination cooling loop is made up of quarter-phase circuit and excess enthalpy fluid loop.Quarter-phase circuit is similar to loop circuit heat pipe operation mechanism, and excess enthalpy fluid loop sets up circulating pump between reservoir and evaporimeter, and under ensureing high heat flux, evaporimeter is also unlikely to evaporate to dryness, thus substantially increases the maximum heat transport of loop circuit heat pipe.This technology, relative to traditional quarter-phase circuit, runs more reliable; Relative to injection cooling, reduce the impact by gravity and acceleration; Relative to conventional heat pipe and loop circuit heat pipe, improve heat flow density and maximum heat transport capability, is a kind of heat transfer unit (HTU) with high input heat flow.

A turbine electricity generation system with ejection circulation loop.Capital equipment has injector, pumping chamber, turbine and loop heat pipe heater.Working steam is introduced in jet pipe and makes adiabatic expansion, the condensation hot water being heated to 90 DEG C is introduced mixing chamber mixing by the high velocity air produced, mixed vapour body is increased to 3-5MPa in the indoor adiabatic deceleration supercharging of diffusion through the pressure that two-step supercharging or three grades are pressurized to 150 DEG C of hot water and enters hot water generator and heat supply, corresponding with Fig. 5 (level pressure heating d-e), enter the external work done of gas-turbine adiabatic expansion, then enter the circulatory system (level pressure heat release f-o); Part steam temperature and pressure meet injector and normally run required entry condition.Ejection circulation system be divided into two loops to see the working medium of the condensation hot water of figure (4) quality o does the external work done of circulation o-c-d-e-f-o, and the working medium that quality is a steam makes ejection circulation a-b-c-d-e-o supercharging condensation hot water.Although the form of condensation heat water and steam is different, the thermodynamic properties of one is very close, and steam generally used is very little compared with condensation heat water quality, can be left in the basket, so be that a certain amount of steam working medium is in work all the time in whole cyclic process.Adiabatic expansion in jet pipe is irreversible adiabatic process on figure (4).C represents vapor stream and injection condensation heat fluid mixed state in mixing chamber, and reversible process c-d represents the adiabatic compression process of mixed liquid in diffusion room, and real process, with friction and shock wave, is irreversible.Process d-e is reduced to constant volume heating process.When whole circulation being regarded as one and being overall, unit mass working medium global cycle caloric receptivity is Q, heats two parts obtain by constant volume heating and level pressure.

Detailed description of the invention
1: ejection circulation
Injector belongs to the one of compressor, and its most basic purposes improves the pressure of working medium.In many thermodynamic cycle process, liquid supercharging equipment is essential, and usually directly will consume mechanical energy.The circulation merit made from the ejection circulation of a forward replaces the mechanical energy directly consumed, and improves whole efficiency.
In order to improve the performance of injector, introduce the main jet with lobe strengthening mixed structure, effect is increased the mixed area of two fluids, adds mass ratio of induced-to-inducing air, improves mixing efficiency, shorten mixing distance.Except improving except flowing on the basis of fixing Rational structure, adopting adjustable ejector to meet the needs that operating mode has larger change simultaneously, increasing adjusting device and also must increase flow resistance.
New multistage injector, just refers to that when working under can meeting optimum state, prime fluid-mixing is whole driving fluids of rear class just, namely not from the multilevel system (being called for short new multistage system) of inter-stage carrying-off certain media.Past due to overemphasize not from inter-stage carrying-off certain media to the harmful effect of induction efficiency, the multilevel system of research is caused to be all will from the specific type of inter-stage carrying-off (condensation) certain media, compared with them, the induction efficiency of new multistage system slightly declines, but exactly because it sacrifices a little efficiency, just be provided with the two large characteristics that other any type injector all cannot possess simultaneously: it does not require from its inter-stage carrying-off certain media, thus a lot of field uses proposition this requisite requirement to injector can be met.It makes its inlet pressure closely by specialized designs, can use inlet pressure difference be less than 20% as level two, thus meets a lot of field uses proposition another strict demand to injector.Due to its this two large special performance, new multistage system is because have certain difference with original injector achievement in research, and it manufactures and designs the particular requirement must following self.
Connected by multiple stage ejector, can realize higher pressure ratio (total pressure ratio Pmn/Pc1), wherein every one-level all can realize a part (point pressure ratio Pmi/Pci) for total pressure ratio.The progression (N) of series connection, just can directly be determined by total pressure ratio and a point pressure ratio.Usually a point pressure ratio at different levels is not identical, as got its mean value (Pmi/Pci), then has:
N＝lg(Pmn/Pci)/lg(Pmi/Pci)
Wherein total pressure ratio is given by design condition; Average pressure ratio at different levels then roughly can be determined by empirical data, also can be solved by original achievement according to expansion ratio at different levels and associated flow.Obviously, series connection progression more to raising total pressure ratio more favourable, but because of progression cross multipair design and management debugging wait all will bring very burden, the more troubles of progression are larger, therefore in most cases with 2-3 level connect be advisable, generally no more than 4 grades.
Total pressure ratio in each inter-stage reasonable distribution, both decide the success or failure of design, also directly had influence on service efficiency.And research shows, uniform distribution is suitable from theory, but is unsuitable for practical application, because it requires that working fluid pressure at different levels is different, and must regulate at any time, thus totally unfavorable to use management.Therefore conveniently use, the distribution of total pressure ratio should follow the principle that the pressure ratio at different levels of uneven distribution-is from front to back successively decreased successively, thus guarantee that in system, injector working fluid at different levels can use identical pressure, decrease the link that ejection system operating pressure at different levels regulates respectively, be conducive to the simplification of equipment.
The selection of injector type at different levels, under prescribed conditions, connected by series ejectors, can realize higher compression ratio (full compression ratio), the every first injector in train all can realize a part (point compression ratio) for full compression ratio.The progression of series connection, just can directly be determined by full compression ratio and these two data of point compression ratio.Usually a point compression ratio at different levels is not identical, if get its mean value, then has:
Progression=(full compression ratio)/(every grade of average compression ratio)
Improve outlet mixture stream pressure, reducing gateway pressure reduction, is the basic goal of multiple stage ejector.Injector is band diffuser according to design feature, accessible most high supercharging pressure level.And with regard to the boost performance of injector, can select according to the characteristic of these injectors pressure ratio scope at different levels.In conjunction with the distribution method of total pressure ratio, by analysis relatively after, the suitable scheme of injector type at different levels can be selected.
