Description
Technical field
The utility model belongs to hot technical field of power generation, particularly relates to a kind of direct expanding solar heating electricity generation system based on overlapping Rankine cycle.
Background technology
Hot generation technology is one of important channel utilizing solar energy.According to the data at concentration solar generating market survey center, global solar electricity generation system (SEGS) installed capacity in 2014 increases by 32%, has reached 4533MW.In the solar power system of all business, system based on parabolic trough collector (PTC) is the most ripe and main flow, constitutes about all operations and the 90% of power station under development installed capacity.
Generally paraboloid trough type heat generating system (PTC-SEGS) uses steam Rankine cycle based on turbo-expander, it has following defect: first, in order to avoid in expanding, water vapour occurs in condensation, only superheated steam (being close to or higher than 673K) could enter turbine.Because water droplet is once formed, the blade of turbine can be clashed at high speed, cause damage and reduce mechanical efficiency.Secondly, steam Rankine cycle is in order to obtain high temperature heat source, and the requirement to heat collection technology is the highest.In groove type heat collector, the glass to metal seal of receiver is a kind of tubular seals, and this not only needs suitable mechanical strength, in addition it is also necessary to air-tightness good under vacuum state.Due to metal and the diverse feature of glass (such as thermal coefficient of expansion and wettability), when running temperature is when about 673K drops to about 300K at night suddenly daytime, and receiver there will be seal failure or degradation phenomena.In solar power station in early days, this inefficacy or degeneration are difficult problems.In order to reach the high temperature of 673K, groove type heat collector focusing ratio is generally more than 60.Big focusing ratio needs high-precision tracking system, safeguards frequently, moving component and the maintenance of gear and replacing.3rd, store high-grade heat highly difficult.Regenerative apparatus is critically important to the continuity ensureing solar electrical energy generation.U.S. SEGS
I power station employing mineral oil can be with accumulation of heat 3 hours as heat-transfer fluid.Below 573K temperature, this technology successfully can be allocated the electric power produced, and meets without public peak load during solar irradiation.But for operating in the more efficient thermal power station under higher heat-collecting temperature, mineral oil can be highly combustible, it is impossible to use.4th, from cost consideration, thermal power station to be the bigger the better.Generally along with the increase of installed capacity, the construction cost of every kilowatt can decline.Reason is those fixed costs in extensive power station and the similar of small-scale power station, and picture turbine, pump, generator are the most in hgher efficiency.Generally paraboloid trough type heat generating system scale is at a few to tens of megawatts, and some is even up to 100 megawatts.This needs leveling land of square meters up to a million, thus can only be at desert or lonely regional Construction.
Above problem can solve by using screw expander.Screw expander is a kind of positive-displacement expansion engine, it uses the principle of rotary displacement, it is to avoid fluid at a high speed.Generally, it is made up of a pair of helical screw and a valve jacket.Fluid flows to other grooves of large volume from the groove of import small size, oppositely drives twin-screw.In this process, the temperature and pressure of fluid declines, and merit is exported by power transmission shaft.Comparing with turbo-expander, screw expander can process gas-liquid mixture, saturated vapor and liquid.It has rapid starting/stopping, it is allowed to thermal source pressure and volume flow wide fluctuations, and rotating speed is low, simple in construction, and maintenance cost is low, and assembling is easy, the features such as mobility is excellent.Screw expander just uses as far back as 20 century 70s in geothermal power generation, and present technology is the most ripe.A lot of steam Rankine cycle power station based on screw expander is had at present in iron and steel and flue gas waste heat, industrial radiation heat, geothermal energy utilization.Existing business-like 50kW-1.5MW on market, the screw expander with water as working medium, isentropic efficiency is at 0.7-0.85.Owing to avoiding superheater, it is used in solar electrical energy generation will having very much prospect.Solar energy heating temperature controls at below 573K, and generating efficiency is similar with the power station based on turbo-expander of main flow.
In view of cost benefit, the one of screw expander is big, and defect is low Design compression ratio.Existing Power Plant Design pressure ratio is typically at 2.5-8.This means if given saturated-steam temperature is 523K(correspondence saturation pressure is 3.98MPa), design condensation temperature should be higher than that 424K(correspondence saturation pressure is 0.49MPa).Available in high-temperature steam can will be unable to by the abundant conversion of single screw expander.A solution is two or more screw machine assembled in series.But so complicated design (the especially goodness of fit in axle center).The feasibility of screw expander series connection there is presently no and is proved.
In view of this, a kind of direct expanding solar heating electricity generation system based on overlapping Rankine cycle of necessary offer, it can run at low ambient temperatures well, there is higher generating efficiency, be suitable to distributed construction on a small scale, the technology of thermal-arrest and accumulation of heat requires the lowest, and has high stability and high reliability.
