Abstract
The invention discloses a runoff kinetic energy power plant, which comprises the facilities such as an underwater axial-flow type synchronous generator (patent application number: 200910183696.5), a gauge pile, a buoyancy tank, a connection rod, a slip ring, and a grid-connected system and the like, and realizes the arrayed hydroelectric generation of the natural kinetic energy of river runoff with low investment and high efficiency in a scientific and innovative way under the premise of preventing the disasters and protecting the ecology without influencing the river running and the irrigation. Through verification, when the velocity of the water flow is 3m/s, the energy density of the water flow is 13500w/m<2>.s and 20 times higher than the energy density (600w/m<2>.s) of the wind energy with the same velocity. The perennially lost water energy is changed into electric power needed by the national economy and the people's livelihood, so as to provide cheap and green renewable energy to the users in the neighborhood; and the carbon-free generation manner is in coincidence with the demands of the man and the nature, the economy and the environment protection, and the harmonious coexistence and the sustainable development.
Description
Technical field
The runoff kinetic energy generating field that the present invention relates in the river, the river makes up.
Background technique
The our times energy scarcity, scarcity of resources, energy-saving and emission-reduction and development renewable and clean energy resource (as solar energy, water energy, wind energy, geothermal power etc.) are advocated in environmental deterioration, become the international competitively focus of development.China's economy and the people's livelihood are in and continue extraordinary developing period at present, and power shortages have been a big bottleneck of restriction national economy sustainable development.Hydroelectric power proportion in renewable energy sources is bigger, and the construction in water power plant must possess abundant waterpower resourses and special landform, physical features, geological condition, needs to drop into a large amount of human and material resources and financial resources.Hydroelectric power can be implemented equally as long as The turbulent river crashes its way through in the middle and lower reaches area that is located in great rivers.According to " water resources in china " verification that Lu Jinkai, Du Guohuan write, the average annual run-off in China rivers and creeks is 2.65x10
13m
3, wherein just there is 9.335x10 every year in the Changjiang river
11m
3The water yield, fall and east flows into the sea with physical features is slow.Learn that according to law of conservation of energy water can fade to kinetic energy by potential energy, its summation remains unchanged, and kinetic energy can be represented with following physical equation:
In the formula: E is the kinetic energy of current, and M is a flow, and V is a flow velocity.The size that shows flow kinetic energy in the formula be directly proportional with the quadratic power of the first power of flow and flow velocity (real fluid kinetic energy should calculate with the bernoulli's equation of complexity).
Experiment confirm, water velocity are when 3m/s, and energy density can reach 13500W/m.s, exceed how 20 times than the energy density (600W/m.s) with fast wind-force! And the section face of the main rivers flow velocity of China more than 2m/s is a lot, and they are containing huge potential for commercial electricity production.Therefore, in the middle and lower reaches area of China's great rivers, utilizing abundant, stable natural current, build the runoff kinetic energy generating field, is the another innovation that water can utilize.
Summary of the invention
Runoff kinetic energy generating field of the present invention be with " axial flow synchronous generator under water " (application for a patent for invention number: 200910183696.5), reinforced concrete dowel pile, steel buoyancy tank; slip ring; connecting rod, facilities such as conflux cable and grid-connected system constitute, and are not influencing navigation; irrigate; take precautions against natural calamities and the prerequisite of ecological protection under, populous, economically developed; the plains region of hydroelectric resources scarcity; utilize natural; cheap; carbon-free green water energy with scientific and reasonable and innovative approach practical simple, is realized instant effect; drop into low; the efficient height, the runoff generating of scale, this is in the renewable energy sources; resource and development, the model of the harmonious doulbe-sides' victory of economy and environment.Solar energy is compared in the runoff generating, and wind energy generating plant is simple and easy, and is with low cost, and resource is stable, and supply and demand is accessible.Because water is incompressible liquid, learn according to energy transfer and conservation law, after part water reduces water wheels acting kinetic energy, can continue to obtain the transmission of upper waters energy and replenish, can continue to promote downstream water wheels rotary electrification.Because the runoff water yield is continually, and is inexhaustible, so runoff kinetic energy also is nexhaustible.If any the generating field of hundred " axial flow synchronous generator under water " composition array 12MW, annual electricity generating capacity 1.05 hundred million degree can be saved 0.37 hundred million ton of coal, reduce by 0.925 hundred million ton of discharge of poisonous waste.Obviously, realize that the generating of scale runoff is the inevitable outcome of fluid dynamic theory and social practice, its society and expanding economy prospect will be very fine.
