Background technique
Along with developing rapidly of China's economic, the primary energy consumption total amount of China is increasing, adds that the energy of China's " rich coal, oil-poor, weak breath " is possessed structure, makes the accounting of coal consumption in China's primary energy very big.Exploitation and the utilization of a large amount of coal resources, brought huge environmental issue, as acid rain, greenhouse effect, haze etc.
Under this background, the important pushing hands of China using energy-conserving and environment-protective as the strategic transformation of promotion national economy, and be defined as one of seven great strategy new industries.Because national policy is helped, add the wide market space, various circles of society have strengthened the technological development of energy-conserving and environment-protective and new energy field.And as wherein heat recovery and the photothermal power generation field in important segmentation field, be also like this.
At present, in energy-saving field, middle high-temperature flue gas heat recovery technology is substantially ripe, flue-gas temperature is greater than 250 ℃ of above residual heat resources, due to its higher energy quality, make it can be used for producing the steam of generating use, make residual heat resources be converted into electric energy, and obtained tremendous development in engineering application.And in industrial enterprise, also exist in a large number lower than 250 ℃ of following fume afterheat resources, although its heat recovery equipment and engineering design technology are ripe, but because its producing steam quality is low, cannot be converted on a large scale electric energy, thereby limit the feasibility of its heat recovery.
At new energy field, photovoltaic generation has formed huge industrial chain; But the discontinuity of photovoltaic generation, makes the quality of electric power that photovoltaic plant produces, and cannot compare with conventional power plant.Heat accumulation mode can be passed through in photo-thermal power station, the quality that has greatly improved solar power station generating dutation and transmitted electric power, and it possesses the extensive coal fired power plant that substitutes, and bears the important task of electrical network basis power load.Yet because photothermal power generation related industry is at an early stage of development, its cost of electricity-generating, far above coal fired power plant, is even compared also expensive upper one times of left and right with photovoltaic plant.Adding country, to foster policy uncertain, causes the photo-thermal power station investment repayment phase long, do not possess trade investment and be worth.Above-mentioned factor has restricted the development of whole photothermal power generation industrial chain jointly.
In sum, the present utility model is developed according to the different characteristics in above-mentioned two fields, has designed a kind of novel solar-thermal generating system, makes it to possess cheap power supply cost, thereby promotes the cooperative development of low temperature heat and photothermal power generation industry.
Summary of the invention
For solving the problem of above-mentioned middle existence, the utility model provides a kind of tower solar-thermal generating system based on low temperature heat, a large amount of cryogenic waste heat resources that this system has not only effectively utilized industrial enterprise to exist, and increased solar energy heat utilization part, thereby improved total generated energy in power station, and made power station investment possess good economic benefit.Technological scheme described in the utility model is as follows:
A tower solar-thermal generating system based on low temperature heat, comprising:
Heliostat battle array, thermal-arrest tower, sloppy heat salt storage tank, hot melt salt storage tank, low temperature exhaust heat boiler, steam superheater, Turbo-generator Set, condenser system; Low temperature exhaust heat boiler is connected with vapour condenser with steam superheater respectively; Steam superheater is connected with Turbo-generator Set; Hot solution storage tank, sloppy heat salt storage tank are connected with thermal-arrest tower respectively; Described Turbo-generator Set is also connected with described vapour condenser.
The beneficial effect of the technological scheme that the utility model provides is:
This technology, on the basis based on the low-temperature flue gas waste heat utilization of resources, has been developed tower type solar solar-thermal generating system; The generation engineering that adopts the technical program to build, reclaimed the low-temperature flue gas waste heat resource of a large amount of discharges at present, utilized again sunlight heat resource, reduced on the whole new energy power stations operating cost, improved the gross generation in power station, make in the situation that not relying on the special subsidy of country, institute builds a power station and possesses trade investment value, thereby promotes the application of power-saving technology and new energy.
Accompanying drawing explanation
Accompanying drawing is system principle structural representation of the present utility model.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail:
As shown in drawings, this figure has shown system principle structure of the present utility model, comprises heliostat battle array 1, thermal-arrest tower 2, hot melt salt storage tank 3, sloppy heat salt storage tank 4, steam superheater 5, low temperature exhaust heat boiler 6, Turbo-generator Set 7, vapour condenser 8.Described heliostat battle array 1, thermal-arrest tower 2, for absorbing solar energy heating fused salt, are connected with hot melt salt storage tank 3, sloppy heat salt storage tank 4; Described low temperature exhaust heat boiler 6 produces saturated vapour, and is connected with steam superheater 5, Turbo-generator Set 7, vapour condenser 8.
Above-mentioned exhaust heat boiler, by absorbing the cryogenic waste heat resource of industrial enterprise, produces low-pressure saturated steam.
Above-mentioned steam generator, is used to the high-temperature molten salt of self-heating fused salt storage tank, heats the saturated vapour that exhaust heat boiler produces, so that it is overheated.
The detailed process of the present embodiment is: on the one hand, sunlight reflexes to thermal-arrest tower 2 by heliostat battle array 1, and by assembling solar beam, heating is from the low-temperature molten salt of sloppy heat salt storage tank 4, and the high-temperature molten salt that thermal-arrest tower 2 produces enters hot melt salt storage tank 3; High-temperature molten salt from hot melt salt storage tank enters steam superheater 5 and saturated vapour heat exchange, and after heat exchange, temperature reduces and becomes low-temperature molten salt, and enters sloppy heat salt storage tank 4.
On the other hand, from the water of vapour condenser 8, enter low temperature exhaust heat boiler 6, be heated generation saturated vapour; Saturated vapour deliver to steam superheater 5 overheated after, enter Turbo-generator Set 7 acting generating, do the steam completing and be condensed into water in vapour condenser 8, be admitted to low temperature exhaust heat boiler 6.
