Description


[0001] The present invention is related to a system for electric generating using accumulation pressure to impact a turbine provided in an electric generator taking advantage of high-speed fluid generated by mixing of high pressure air and water, thereby the electric generator can be run for generating electricity, and to supply electric power for the electricity consumptive elements on the pressure-accumulation electric generating system wi th part of the electricity generated, in order that the pressure-accumulation electric generating system can be run more smoothly.

[0002] Main providers in the global energy-source markets mostly are those for electricity generating by firepower and nuclear energy; although they can provide electric power for living and economic development, energy source consumption, environmental pollution and the problems to the descendants they make are unsolvable. By the fact that environmental pollution gets more and more serious, and the crisis of energy source gradually gets evident, obtaining regenerative energy sources have been the mainstream in the future for energy sources; the regenerative energy sources are released energies that have existed in the nature, they can be used by non public polluting techniques, e.g. they include: solar energy, wind power, hydraulic power, subterranean heat energy, biomass energy etc. However, among the variant modes of electricity generating, the hydraulic-power generating mode is one of the most effective modes, the reason is that solar energy has the limitation of time and appropriate weather for electricity generating, wind power for electricity generating also has the limitation of season and site, subterranean energy has the limitation of district, and the technique of biomass energy has not been completely mature yet. Water is the material that can be obtained easiest, when water flow and air flow with the same speed are respectively impacted onto a turbine provided on an electric generator, by virtue that the quantity of the water is much larger than that of the air, the efficient dynamic energy converted for the electric generator from the water will relatively be much larger.

[0003] However, obtaining and converting of the regenerative energy sources normally can only be achieved by having larger sites and spaces, general small electric generators mainly use petrochemical fuels for electricity generating, i.e.: diesel electric generators and gasoline electric generators. These types of electric generators will result more serious environmental pollution in practice except that they can speedy consumption of energy sources.

[0004] In view of the above stated, the present invention aims at providing a small electric generating system using regenerative energy to get an object of saving energy source and generating electricity. The pressure-accumulation electric generating system of the present invention mainly comprises: a fluid spraying device with a pressure accumulation tank, the fluid spraying device is provided with a fluid spraying pipe in communication with the pressure accumulation tank; an electric generator with a turbine, when the turbine runs, the electric generator generates electricity; and a pressurizing unit connecting with the fluid spraying device. By injecting the fluid into the pressure accumulation tank after pressurizing of the fluid by the pressurizing unit, the fluid is released from the fluid spraying pipe to impact the turbine with a high speed; the turbine runs after impact by the fluid to drive the electric generator to generate electric power. The fluid includes air and water in practice, by the feature that the air has a higher expansion ratio after pressure releasing to impel the water with higher unit specific weight to form a high pressure fluid with mixed air and water; the fluid obtains an optimum energy transferring effect when it impacts the turbine. And after running the electric generating system, part of the electricity generated can afford using of the pressurizing unit, and can help the electric generating system to do the pressurizing operation of mixing air and water.

[0005] Before the pressure-accumulation electric generating system of the present invention generates electricity normally, the pressure accumulation tank in the fluid spraying device can generate spraying-flow pressure at the initial stage by a mode of direct pressurizing by the electric power of an electric cell or a high-pressure air bottle, thereby an electric generator runs to generates electricity; and when the pressure-accumulation electric generating system generates electric power, part of the electricity generated affords using of the pressurizing unit. By virtue that the amount of the electric power generated by the pressure-accumulation electric generating system is larger than that of consumption electricity of the pressurizing unit, the electric power can be supplied for the pressurizing unit as a sustaining aid to increase pressure for the pressure-accumulation electric generating system. Electric generating of the pressure-accumulation electric generating system can be smoother. After water in the spraying flow impacting on the turbine is collected, it is injected into the fluid spraying device again to have the water resource recycled for using, thereby no public damage and pollution can be generated.

And a fluid collecting tank 63 is provided under the penetrated area 62 of the base 60, so that the water after being impacted onto the turbine 21 can be collected to be drawn by the water pump 31 for reuse.
