Abstract
This invention is about the multistage flat solar heat collector central vapor generating system. It is made up of the multistage flat solar heat collector, the mirror reflection heat collector, the intermediate pressure vapor tank and the normal steam turbine electric power plant. The characteristics are that it mainly uses the highly active multistage flat solar heat collector to achieve the tasks of collection of the electrothermal energy. Then it produces the low-pressure vapor that is heated and pressed by the mirror reflection heat collector, which is used to generate electricity. This advantage is low cost colligate efficiency which is good for the economy and the environment.
Description
Technical field
Present technique belongs to solar energy and utilizes scientific domain, exactly is to belong to solar energy heating generating science and technology.
Technical background
In order to utilize solar electrical energy generation, prior art adopts photovoltaic cell and the generating of light collecting thermal-arrest more, has obtained many achievements in this respect, and has begun to take shape certain scale.But to compare cost still higher because prior art and other generating is produced, and large size is promoted the approval that does not also obtain commodity production, and therefore, on the angle of economy and science, further raising awaits.
Summary of the invention
The objective of the invention is for easy technology, lower cost utilizes the solar energy heating generating fully, obtains higher income.Realization has the operation of commerciality on a large scale of strong competitive ability.
The object of the present invention is achieved like this, and the present invention mainly is by the multi-stage, efficient flat-plate solar heat collector, the reflecting condensation heat collector, and medium pressure steam vapour storage tank and the conventional steam turbine power generation factory that is complementary combine.It is characterized in that, mainly adopt the multi-stage, efficient flat-plate solar heat collector, finish the collection of most of generating heat energy, produce low pressure steam,, press the generating of vapour storage tank stable power-supplying factory in sending again by after the reflecting condensation heat collector increasing temperature and pressure.
1, the multi-stage, efficient flat-plate solar heat collector is by elementary, and secondary and final stage three big levels constitute.Elementary can the composition by a plurality of little levels, mainly finish the heating of circulation warm water, make its water temperature near 100 ℃.Then, secondaryly again water is become steam.At last, produce low pressure steam, pump in the reflecting condensation heat collector increasing temperature and pressure level by final stage.Secondary and final stage can be made up of several little levels.
2, low pressure steam makes steam reach 250 ℃-350 ℃ after reflecting condensation heat collector increasing temperature and pressure, when pressure reaches (1.8-4.5) MPa, injects by check valve automatically and presses vapour storage tank.
3, middle pressure vapour storage tank is that a very big height of collection steam flow is incubated firm large-scale setting.The purpose that makes is to stablize supplies with the steamer power station production normally continuously that is complementary with its capacity fully.
4, the power station with institute for medium pressure steam add again can adjust after, the startup steam turbine set normally move generating.This is still to prolong the traditional approach of usefulness at present.
5, the whole generating system all will consider the high heat preservation performance of equipment fully in design, the rational distribution of resources between the performance of firm safety durable, the reliability of automatic sensing system and each system and the significant problem of cost cost.
The present invention compared with prior art has following advantage: 1, the multistage efficiently flat plate collector fabrication and installation of advanced person are easy, and cost is lower, has the commercial competition advantage.2, flat-plate solar heat collector and gathering surface technology of water catchment and usefulness have splendid economy and ecological, environmental protective comprehensive benefit.
Description of drawings
Fig. 1 is a system of the present invention simplified diagram.
Fig. 2 is a final stage flat-plate solar heat collector schematic representation.
Fig. 3 is a final stage flat plate collector sectional elevation schematic representation.
Sequence number among the figure: 1 primary planar type solar thermal collector, 2 level flat plate collectors, 3, the final stage flat plate collector, 4, parabolic mirror, 5 light and heat collection increasing apparatus, 6 circulation warm water pumps, 7 hot water pumps, 8 low pressure steam pumps, 9 steam pumps that boost, 10 check valves are pressed vapour storage tank in 11,12 steam turbine power generation factories, 13 storage vapour sensed systems, 14 flat plate collector cover plates, 15 thermal-arrest plates, 16 pressure steam accumulator bodies, 17 cabinet insulation layers, 18 selectivity efficient coating or plating layers, 19 metallic red outer reflective layer, 20 casing stress framves, 21 conductive metal heat exchange wings.
Embodiment
At first, circulation warm water adds primary planar type solar thermal collector 1, when treating that solar energy is heated to water near 100 ℃, pumps into secondary flat-plate solar heat collector 2 automatically by hot water pump 7.Become steam behind the heat temperature raising once more through solar energy, pump into final stage flat plate collector 3 by steam pump 8 automatically.Solar energy continue to heat boost to the low pressure steam certain value after, the steam pump 9 that boosts will pump into light-condensing and heat-collecting device 5 to low pressure steam automatically.Under the heat temperature raising situation that solar energy is concentrated, steam can reach 250 ℃-350 ℃, pressure can reach more than the 1.8MPa, and via check valve 10, continuously medium pressure steam is injected medium temperature and medium pressure vapour storage tank 11 in up-time at solar energy, supply with the steam turbine power generation factory 12 that is complementary by the medium pressure steam jar at last and use generating.And the circulating water of power station is failed back flat plate collector again and is used continuously.As long as stop when needing to stop production heat collector 1 is supplied water.
System of the present invention is in the process of running, and the solar energy that multistage flat plate collector gathers will be the major component of power generation energy resource.Therefore, just make its cost be lower than existing thermal power station.But,, how to have used existing advanced person's flat plate collector technology here, it is significantly lowered at the following cost of prerequisite that effect heightens, remain the problem that has a high potential.
