Description
One, technical field
The invention belongs to optical technical field, belong to high-energy light-gathering space weapon field especially.
Two, background technology
The technology close with the present invention is disc type solar energy heat generating system and tower-type solar thermal power generating system (drawing from " generation of electricity by new energy technology " China Electric Power Publishing House).
The disc type solar energy heat generating system
Utilize rotational paraboloid mirror to collect sun power, this is a notion that proposes very early.As far back as the seventies in 19th century, the small-sized solar power station that builds up in the Paris, FRA suburbs is exactly an early stage point focusing disc type solar energy power system.Just in recent years, along with developing rapidly of novel motive power machine and other correlation technique, so that cooperate the new type power genset to constitute modern disc type solar energy thermal electric generator rotational paraboloid mirror.
Over nearly 20 years, the initial purpose of exploitation disc type solar energy thermal electric generator is to use for the space.According to existing data analysis, the disc type solar energy thermal electric generator is compared with solar energy photovoltaic generator, and the installation weight of its unit generated output is lighter.Use as the space, this is a crucial technical parameter.Now, main application purpose is for solving the powerup issue of outlying Desert Area, and this economically may be more worthwhile.
The disc type solar energy heat generating system constitutes complete optically focused, thermal-arrest and a generator unit based on single rotational paraboloid mirror.Owing to can not do very greatly with single rotational paraboloid mirror, therefore the single power of this solar energy thermal-power-generating device is all smaller, is generally 5～50kW.It can generate electricity separately dispersedly, also can form a bigger electricity generation system by a plurality of.
Device constitutes
The principle of work of disc type solar energy heat generating system is fairly simple.Utilize rotational paraboloid mirror, the incident solar ray collecting is gone up on one point, be point focusing.Place the sunlight receiver at the focus place, heating working medium drives the dynamic power device generating; Or directly place cluster engine at the focus place and generate electricity, as the disc type solar energy Stirling Blast Furnace Top Gas Recovery Turbine Unit (TRT) that constitutes by the Stirling engine group, technical more advanced.
The disc type solar energy thermal electric generator is made up of 3 parts substantially: rotational paraboloid mirror, receiver and tracking means.
(1) rotational paraboloid mirror
The mirror surface structure of the mirror surface structure of rotational paraboloid mirror and grooved parabolic mirror is just the same, all is silvered glass back side mirror usually.A rotational paraboloid mirror is generally formed by tens minute surface group structures, makes supporter with the steel construction ring, and whole dish mirror is installed on concrete or the steel construction frame by sun altitude and position angle gear drive.The elevation angle gear reduction rate is 18300: 1, and the position angle gear reduction rate is 23850: 1, in time follows the tracks of the sun by the control of double-axis tracking device thus.
The optically focused ratio of disc type catoptron can be up to 500～6000.The focus place can produce very high temperature, generally all more than 650 ℃.
(2) receiver
Receiver is installed on the focus of disc type catoptron by support bar.Existing test unit has adopted two kinds of dynamic power modes, and a kind of is the generating of organic working medium Rankine cycle engine, and a kind of is the generating of gas working medium Bu Laodun circulation Stirling engine.
1. organic working medium Rankine cycle engine generating
The receiver of this driven power generation system mostly is single flow cavity type boiler, and heat-carrying working medium is used silicone oil more, and its advantage is a not pressure-bearing of receiver, receiver very light weight like this, design and operation and safeguard all simple than religion.Receiver outsourcing heat-insulation layer, opening part dress fan housing is to reduce the thermal loss of receiver.The turnover oil pipe lays along the receiver support bar.Can reduce sunshade like this and prevent mechanical damage.
Organic working medium mostly is toluene, adopts the single-stage axial steam turbine to drive the high speed alternator generating, and unit is installed in by the mirror holder, with dish mirror symmetric arrangement, plays the gravitational equilibrium effect to the dish mirror.Working medium is carried out heat exchange by heat exchanger and silicone oil, and steam turbine working medium temperature in is 400 ℃.
2. gas working medium Bu Laodun circulation Stirling engine generating
This driven power generation system is the focus place that the stirling generator group is directly installed on the disc type catoptron.The sunlight that focuses on directly drops on the heat absorption assembly of engine head, heats its gas inside working medium.The running temperature of this system is many at 800～1000 ℃.
Stirling engine is the closed loop piston engine, and it is a kind of ancient engine, is Scotsman R.Stirling as far back as 1816 and invents, so be called Stirling engine.Its appearance and the application internal combustion engine early than popularization and application at present far away.
Stirling round-robin working medium is helium, and it promotes periodic duty by outside heat supply, so Stirling engine also claims external combustion engine.The circulation of whole Stirling is made up of two isothermal processs and two isochoric process, promptly isotherm compression, etc. appearance heating, isothermal expansion and etc. put heat.Gas working medium heating in expansion process, gas working medium heat release in compression process.Because circulation is heating and heat release under isothermal, satisfies the second law of thermodynamics, so the Stirling round-robin thermal efficiency is identical with the Carnot cycle with maximum heat engine efficiency in theory.Therefore, the efficient of actual Stirling engine is in identical temperature range of operation, all higher than the efficient of any hot machine.
(3) tracking means
The disc type condenser adopts the double-axis tracking device, and the tracking mode of heliostat is identical in its fundamental mode and the tower power station.In the disc type solar energy thermal electric generator, condenser makes catoptron follow the tracks of the sun by the elevation angle and the position angle gear drive of tracking means control mirror holder.
Tower-type solar thermal power generating system
Tower-type solar thermal power generating system also claims the concentrated solar heat power generation system.
Tower-type solar thermal power generating system is to utilize numerous plane reflection lens arrays, solar radiation is reflexed on the sun receiver that places high top of tower, and heating working medium produces superheated vapor, the generating of driving steam turbine genset, thus sun power is converted to electric energy.Obviously, the plane mirror number in the array is many more, and then its optically focused is bigger than more, and the heat-collecting temperature of receiver is also just high.
Electric power station system constitutes
Total system is made of 4 parts: beam condensing unit, heat collector, regenerative apparatus and steamer Blast Furnace Top Gas Recovery Turbine Unit (TRT).
(1) beam condensing unit
The beam condensing unit at tower type solar energy thermal power generation station is the plane reflection lens array group who arranges by certain arrangement mode in a large number.They by four quadrants be distributed in tall and big center receive tower around, forms a huge Jing Chang, obviously, the Power Plant Design capacity is bigger, the catoptron area that then needs is also bigger, mirror field size also just more greatly.Rule of thumb, the long-pending 2.43km that is about of the mirror scene of generated output 100MW needs
2
1. heliostat
Heliostat is the most basic optical unit body in the tower type solar thermo-power station, and it is made up of level crossing, mirror holder and follower 3 parts.Level crossing is contained on the mirror holder, and it is instantaneous from the motion tracking sun to drive minute surface by its tracking means.
Heliostat structure: be to adopt to have the plane mirror that good reflection rate film makes (a), be contained in the transparent membrane enclosed globe shade.Transparent membrane has very high sunlight transmitance.The bracing frame of this heliostat is very light, so the electric power consumption of follower can be very little.(b) be to adopt aluminium or silver to be the glass back mirror of reflectorized material, the catoptron area of a heliostat is generally 30～40m
2, combine by some little mirror surfaces.The minute surface area of large-scale heliostat is approximately by 100m
2, for example the minute surface area of part heliostat is 98m in U.S.'s sun II number tower power station
2Because heliostat is far away apart from the cat head receiver, in order to make sunlight excessive defocusing of unlikely generation after the heliostat reflection, so that flashing back the sunlight more than 95% falls on the receiver of cat head, general minute surface is the planoconcave mirror with small radian.This small radian be exactly sun subtended angle 16 '.The heliostat of this structure is all adopted at existing most of tower type solar energy thermal power generations station at present.
A large-scale tower type solar energy thermal power generation station is adorned in its mirror field usually by several thousand heliostats, therefore has very high light concentrating times.Usually have 500～3000 times, working temperature is all more than 350 ℃.So tower-type solar thermal power generating system also claims the high temperature solar heat generating system.
Therefore heliostat is one of critical component of tower type solar power house, also is the main investment part in power station, and it occupies the main place in power station, and the performance to heliostat has strict demand, and specific requirement is: 1. specular reflectance height; 2. the minute surface flatness error less than 16 '; 3. integral mechanical structure intensity height, the attack of the anti-8 grades of typhoons of energy in service; 4. stable; 5. all weather operations; 6. can produce in enormous quantities; 7. be easy to install; 8. safeguard and lack long working life.
2. Jing Chang design
The Jing Chang design is a most important component in the global design of tower type solar energy thermal power generation station. method for designing is: at first select specific season, the for example middle winter, arrange the linear north-south array of catoptron then, make it not have sunshade each other, and can intercept the maximum possible share of incident solar radiation. heliostat is permanent stationary positioned, points to and directly aims at the sun receiver that is installed in cat head.
3. follow the tracks of and monitor controller
Control system in the tower power station is a sets of computer, be used to monitor and control the ruuning situation of each system of power station, the Collaborative Control in whole power station is provided. because tower power station formula has huge heliostat field, every heliostat all needs independent control, follow the tracks of the sun, so in the solar energy thermal-power-generating station, the control system in tower power station is the most complicated.
In each system in whole power station a lot of sensors are housed, a large amount of continuous and the measurement data of being interrupted in service and alerting signal are from reaching central control room everywhere. and host record and demonstration are arranged. and show system pipeline in service and instrument and indication valve duty simultaneously.
(2) center receives tower
The center is accepted tower and is also claimed the power tower, is the Accumulated Heat Units at tower type solar energy thermal power generation station. and it is made up of solar radiation receiver and high tower two parts, and receiver is installed on the high cat head, and working medium conveyance conduit etc. is arranged in the hollow tower body.
1. reception tower
(1) structure. roughly by two kinds of forms, promptly cavity type and outside are subjected to the light type to the solar radiation receiver at tower type solar energy thermal power generation station.On structure, no matter the receiver of which kind of form, be basic heat exchange unit all with the comb bundle, just by the principle of work difference, group constitutes multi-form. and the principle of work of cavity type receiver is that numerous comb bundles surround the cavity with certain opening size, and sunlight incides on the cavity inside tube wall from the cavity opening, carries out heat exchange at cavity inside. obviously, the thermal loss of this cavity type receiver can be reduced to minimum, is suitable for adopting the steamer power generation cycle of modern high parameter.
It is the cylinder that numerous comb bundles surround certain diameter that the outside is subjected to the principle of work of light type receiver, outside generating surface is directly exposed to, sunlight incides and carries out heat exchange on the surface. compares with the cavity type receiver, it is big that its thermal loss is obviously wanted. but the receiver of this version can more acceptant mirror field edge on the reflected radiation of heliostat, so it more is applicable to large-scale tower-type solar thermal power generating system.
On the heat exchange principle, receiver all is the solar radiation direct current cooker. in fact, initial deviser also conceives according to the direct current cooker principle. as the comb bundle of heat exchange basic unit body, adopt the heat-resisting copper pipe of little caliber to make. the outside is subjected to the comb bundle of light type receiver, its outside surface needs the coated with high temperature selective absorbing film. and opposite, the cavity type receiver need not coating by its heat absorption principle. and by contrast, this also is an advantage of cavity type receiver.
2. tower
In the mirror field at tower type solar energy thermal power generation station, standing has a very high perpendicular tower.Numerous heliostat that distributes all around of tower, receiver is installed on the top of tower.The heliostat of sunlight around the tower reflexes to receiver .. working medium on the cat head is delivered to cat head through pipeline from ground receiver heating, and the working medium after the heating is sent ground back to through pipeline again. and connecting line and control interconnection all lay along tower between all ground and the cat head receiver.
At present, used perpendicular tower in the tower type solar energy thermal power generation station has two kinds of patterns of reinforced concrete and steel framework on the structure.
The height of perpendicular tower is decided by the scale of Jing Chang. the design capacity in power station is bigger, and then the scale of Jing Chang is bigger, and perpendicular tower is also just high. for example, the tower type solar energy thermal power generation station that European Union builds in Italian Sicily, mirror field floor area 3.5 ten thousand m
2, tower height 55m, U.S. sun II number tower power station, Jing Chang takes up an area of 440,000 m
2, tower height 91m..
(3) regenerative apparatus
The regenerative apparatus at tower type solar energy thermal power generation station, two open type heat storage slots of pressure-bearing not normally: one is cold salt bath, a hot salt bath, make thermal storage medium with salt-mixture. the cold salt in the cold salt bath, by pumping toward the receiver of cat head, through solar energy heating to high temperature, store in the hot salt in the groove. during operation, hot salt adds hot water by steam generator and becomes superheated vapor, drives the generating of steam turbine engine group, and then returns cold salt bath.
Operating condition by salt-mixture is near normal pressure, so receiver pressure-bearing not, allows to adopt the thin-wall steel tube manufacturing, thereby can improve the heat flow density of heat-transfer pipe, reduce the physical dimension of receiver, so that the radiation and the convection heat losses that reduce receiver, make receiver have higher absorption efficiency.
From using, the salt-mixture here has heat-carrying and the hot dual-use function of storage concurrently, makes hold over system become simple and efficient. generally store the thermal efficiency greater than 91%.
