Description
Technical field
The present invention relates to wind-power generating system, particularly a kind of comprehensive energy duct well power station in conjunction with solar energy, geothermal power.
Background technique
The mankind to fossil fuel, as oil, coal etc. seize the environmetal impact that causes increasingly expand, and this kind of energy supply is limited, also increasingly exhausted.Therefore, utilize the power generation system of wind energy, solar thermal energy all to be paid much attention at world wide, also obtain the development of advancing by leaps and bounds in recent years.Common drive the wind-driven generator of blade with natural wind, be converted into mechanical energy again drive generator using solar energy as thermal source, the industry of entering utilizes the stage all.But above-mentionedly utilize the form of wind energy and solar energy all to exist to depend on unduly the natural condition such as wind-force, sunshine, defect that complex structure, input-output ratio are low.For above-mentioned deficiency, wind energy 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 solar energy heating air, drives wind-driven generator to produce electric energy by forming upward flow perpendicular to the air channel on ground.Such as, solar chimney wind turbine described by International Publication WO01/96740A, namely disclose air preheat by solar energy greenhouse, the air channel imported again perpendicular to ground forms upward flow, drive the turbo machine drive electrical generators work in air channel, it coordinates the state modulator such as rotating speed, moment of generator by complicated computer controlled system; And for example Chinese patent application CN101487452A, CN102128150A, is disclosed basic principle and structure that solar energy and energy and wind energy integrative utilize, and considers the form being realized heat energy, luminous energy comprehensive utilization by the structure such as photovoltaic cell, heat conductive tube.
As the scheme of public technology front exemplified, all have employed aforesaid basic principle, the air of solar energy preheating rises in vertical air plenums, and position suitable in air channel drives the generating of turbine, impeller drive electrical generators.But facts have proved, only according to above-mentioned basic principle, the effective capacity with industrial utilization can not be realized, and published technological scheme, described by above-mentioned WO01/96740A, still there is the defect of inefficiency, control principle complexity.Trace it to its cause, first, as everyone knows, the thermal capacity of air and heat conduction efficiency not high, and highly transparent, and be unfavorable for the savings of heat energy, add the guide functions in back segment air channel, air velocity is very large, only by one section of greenhouse type hole capital after selling all securities, the air of flowing just can not be heated to enough temperature, can not form the temperature difference enough with surrounding environment, make the upward flow in air channel can not produce enough speed and pressure.Moreover, published technological scheme is all inadequate to the peak regulation process exporting electric energy, and utilizes the unstable natural energy resources such as solar energy, wind energy to generate electricity, and technical problem the most thorny is at present exactly to obtain stable electric energy output, especially, time grid-connected with public electric wire net, this defect is more outstanding.
As the scheme of public technology front exemplified, the effective capacity with industrial utilization can not be realized, except can not fully excavate except the potential energy of natural energy resources, wind generating unit as main electrical generation components does not consider the particularity of this type systematic and in addition special structural design yet, therefore, the energy that can do work cannot all be made full use of.

Moreover as the scheme of public technology front exemplified, all have employed aforesaid basic principle, the air of solar energy preheating rises in vertical air plenums, position suitable in air channel drives the generating of turbine, impeller drive electrical generators.But all do not relate to the processing mode of wind top of tower tail gas stream.Facts have proved, when acting air-flow tail gas in air duct well is in tower top discharge to atmosphere environment, owing to also having certain flow velocity, air that is static with the external world or that only have a horizontal flow velocity collides, huge exhaust noise can be produced, and in tower top end turbulization, this turbulent flow also have impact on the smooth and easy degree of exhaust, even can produce tower top structure when serious and destroy.Above-mentioned known technological scheme does not all consider this potential threat.
For this reason, present inventor, for the defect of above-mentioned conventional art, proposes effective solution by the application spy.
