Well power station, comprehensive energy air channel

Technical field

The utility model relates to wind-power generating system, particularly a kind of well power station, comprehensive energy air channel that combines solar energy, geothermal power.

Background technique

Human to fossil fuel, enlarge day by day like the environmetal impact that is caused of seizing of oil, coal etc., and this type energy supply is limited, also exhausted day by day.Therefore, utilize the power generation system of wind energy, solar thermal energy all to be paid much attention to, also obtained the development of advancing by leaps and bounds in recent years at world wide.Common with natural wind drive blade wind-driven generator, be converted into mechanical energy with solar energy again as thermal source and drive generator, all entering industry is utilized the stage.But the above-mentioned form of utilizing wind energy and solar energy all exist to natural condition such as wind-force, sunshine depend on unduly, complex structure, the low defective of input-output ratio.To above-mentioned deficiency, wind energy is combined with solar thermal energy, the using energy source means of learning from other's strong points to offset one's weaknesses also are seen in open.Its basic principle is with the solar energy heated air, forms upward flow through the air channel perpendicular to ground and drives wind-driven generator generation electric energy.For example; The described solar chimney wind turbine of International Publication WO01/96740A; Promptly disclose through solar energy greenhouse air preheat; The air channel that imports again perpendicular to ground forms upward flow, and the turbo machine that drives in the air channel drives generator work, and it passes through complicated computer controlled system and coordinates parameter controls such as the rotating speed of generator, moment; And for example one Chinese patent application CN101487452A, CN102128150A disclose basic principle and structure that solar energy and energy and wind energy integrative utilize, and consider the form that realizes heat energy, luminous energy comprehensive utilization through structures such as photovoltaic cell, heat conductive tubes.

The scheme of public technology as preceding giving an example has all adopted aforesaid basic principle, and the air of solar energy preheating rises in vertical air channel, and suitable position drives turbine in the air channel, impeller drives generator for electricity generation.But facts have proved,, can not realize having the effective capacity of industrial utilization only according to above-mentioned basic principle, and disclosed technological scheme, described like above-mentioned WO01/96740A, still there are inefficiency, the complicated defective of control principle.Trace it to its cause, at first, well-known; The thermal capacity of air and heat conduction efficiency are not high, and highly transparent, and are unfavorable for the savings of heat energy; Add the guide functions in back segment air channel, air velocity is very big, only through one section greenhouse type hole capital after selling all securities; Flow air just can not be heated to enough temperature, can not form the temperature difference enough with surrounding environment, makes the upward flow in the air channel can not produce enough speed and pressure.Moreover; Disclosed technological scheme is handled all inadequate to the peak regulation of output electric energy, and utilizes unstable natural energy resources such as solar energy, wind energy to generate electricity, and the most thorny technical problem is exactly to obtain stable electric energy output at present; When especially being incorporated into the power networks with public electric wire net, this defective is more outstanding.

Like the scheme of public technology of preceding giving an example; Can not realize having the effective capacity of industrial utilization; Except that can not fully excavating the potential energy of natural energy resources; Do not consider the particularity of this type systematic and therefore special structural design in addition, all can't make full use of the energy that can do work as the wind generating unit of main generating parts yet.

In the above-mentioned generation mode, within the specific limits, the air channel well is high more, stable, the powerful upward flow of easier acquisition; The diameter of air channel well is big more, is easy to adopt major diameter, relatively low speed, generator system efficiently more.But build major diameter and higher relatively air channel well, belonged to huge engineering, its investment is difficult to regain effectively through the production capacity in later stage.In view of the above; Though have in order to the technological scheme that overcomes this defective open; For example Chinese patent discloses CN201246272Y and CN2851632Y, and the former provides the technological scheme that makes up the air channel well with light-duty splicing construction, but its structural strength still dislikes not enough; The resonance that high velocity air possibly cause can't be born, thereby high-intensity application in industry can not be dropped into; The latter has then sacrificed necessary height under the prerequisite that enlarges cross section diameter as far as possible, airspeed and smoothness all can't effectively be improved.

Moreover the scheme of public technology as preceding giving an example has all adopted aforesaid basic principle, and the air of solar energy preheating rises in vertical air channel, and position suitable in the air channel drives turbine, impeller drives generator for electricity generation.But the processing mode that does not all relate to wind top of tower tail gas stream.Facts have proved; Acting air-flow tail gas in the well of air channel is when tower top discharge is in atmosphere environment, owing to also have certain flow velocity, air static with the external world or that only have a horizontal flow velocity collides; Can produce huge exhaust noise; And in cat head end turbulization, this turbulent flow has also influenced the smooth and easy degree of exhaust, under the serious situation even can produce destroy the cat head structure.Above-mentioned technique known scheme is not all considered this potential threat.
