Description
Technical field
The utility model is solar energy and fuel compensating generator, belongs to energy field.
Background technology
Existing fuel generating device is mainly coal-fired power plant and oil fired power station, is with the water in fuel heating steam boiler, makes water become the superheated steam that steam is further heated as HTHP again and promotes steam turbine generator generating.And the burning of fuel will be discharged a large amount of pernicious gases, contaminated environment.Solar energy is clean energy resource, the existing scheme with the middle high-temp solar heat collectors such as slot type and fuel complemental power-generation, but all need with focusing mirror, and speculum cost is high, can only utilize again direct light.On the other hand, the cryogenic applications technology of solar energy is well developed, and especially glass vacuum pipe heat collector and the flat plate collector in solar low-temperature heat collector, has had higher cost performance, and be made into solar water heater, be widely used.Existing solar low-temperature heat collector obtains heat energy than burning at least cheap 3 times of coal.And new patented product all-glass vacuum flat plate collector obtain heat energy will be than burning cheap 5 times of coal.So the fuel power generation function of solar energy and fuel power plant has had very strong complementarity.Past existing enterprise solar energy vacuum tube heat collector, water Baidu from normal temperature is heated to, send fuel vapour boiler to, but this combination solar energy only provides the heat energy of tens cards to each gram of water, compare with the heat that every gram of water is heated to the required hundreds of card of superheated steam from normal temperature, the contribution of solar energy is too little.Have the boiler of being exactly to be evaporated quantitative limitation, hot water not to be used, and therefore, also needs to find more scientific and effective complimentary fashion again.
Summary of the invention:
The purpose of this utility model, be to provide a kind of solar energy and fuel compensating generator, when having the sun, utilize cheap solar energy for power plant saves a part of fuel, to reduce the cost of electricity-generating of power plant and to reduce disposal of pollutants, increase the ratio of regenerative resource in primary energy application.
Technical scheme: the TRT being made up of solar energy and fuel complementation, is characterized in that: heat collector 1 connects water tank 2, and water tank 2 connects vaporizer 4 through water pump 3; Heat collector 12 connects the heat exchanger 14 of vaporizer 4 the insides through circulating pump 13; The venthole of vaporizer 4 connects steam pump 5, steam pump 5 connects fuel vapour pot 6 through check-valves 15, and fuel vapour boiler 6 connects steam turbine generator 7, and steam turbine generator 7 connects condenser 8, condenser 8 connects water pump 16 through reversal valve 17, and water pump 16 connects water tank 2 again; Above-mentioned parts all connect with pipe fitting.
Operation principle: heat collector 1 is stored in water tank 2 water heating, delivers to vaporizer by hot water with water pump 3; Heat collector 12 heat mediums are delivered to heat exchanger 14 through circulating pump 13, provide heat of vaporization to hot water, and making hot water vaporization is Low Temperature Steam, inject fuel vapour boiler be heated to be superheated steam again with steam pump, promote steam turbine generator generating.
Beneficial effect: utilize the solar thermal collector of Cheap highly effective to receive solar energy, the Low Temperature Steam water is vaporized into as containing a large amount of latent heats of vaporization is entered to fuel vapour boiler.Each gram of water becomes superheated steam needs the heat of approximately 800 cards, and the heat of vaporization of water is 540 cards, and every gram of Low Temperature Steam band approximately 600 card heats enter boiler.The heat energy that medium obtains at solar thermal collector is more than what provide in fuel vapour boiler.Utilize solar low-temperature heat collector to coordinate fuel vapour boiler, can save approximately 2/3 fuel, and only have 1/3 of burning coal with the cost that solar low-temperature heat collector obtains heat energy.This had both greatly reduced the production cost of electric power, had reduced again disposal of pollutants, had produced double effects.
