Description
Technical field
The utility model relates to a kind of wind-power electricity generation wind-tunnel, is specifically related to a kind of wind-power electricity generation wind-tunnel that adopts vortex type to increase wind energy density, belongs to technical field of wind power generation.
Background technique
Wind energy resources is very abundant on earth.Chinese feature energy storage capacity 25.3 hundred million MW, coastal and offshore islands available wind energy density is greater than 200W/m
2, land available wind energy density is at 100～200W/m
2Between, land high mountain available wind energy density is at 300～700W/m
2Between.The existing techniques situation: wind-power electricity generation available wind energy density value is low, and wind energy utilization is low.The natural wind energy condition that submits to that artificial wind power equipment is passive can not be in the low wind energy density of every surrounding city zone, and using wind-power electricity generation is that the city directly supplies power.And existing wind power equipment single-machine capacity is little, and peak output can only reach the MW level.
The model utility content
The purpose of the utility model is low in order to solve existing wind-power electricity generation wind-tunnel natural situation wind energy density value; Wind power equipment unit generated output is low; And the problem that can't be applied to the generating of surrounding city zone, and then a kind of wind-power electricity generation wind-tunnel that adopts vortex type to increase wind energy density is provided.
The technological scheme of the utility model is: the wind-power electricity generation wind-tunnel that adopts vortex type to increase wind energy density comprises blower cover, wind-tunnel, wind wheel, the first aperture formula volume damper, a plurality of wind-force air blower of compensating, a plurality of wind-force compensator and a plurality of second aperture formula volume damper; Blower cover and wind-tunnel are coaxially set from right to left, and wind wheel is installed in the outlet end of wind-tunnel, and the first aperture formula volume damper is installed in the outlet end of wind-tunnel; The ratio of the diameter of blower cover and the diameter of wind-tunnel is between 2.5 to 3.5; Offer a plurality of holes on the blower cover, a plurality of holes circular array arranges that each place, hole is equipped with a wind-force compensator; The wind-force air blower of compensating is housed in the wind-force compensator, and the second aperture formula volume damper is installed in the entrance point of wind-force compensator.
The utility model compared with prior art has following effect: the ratio of the diameter of the blower cover of the utility model and the diameter of wind-tunnel is between 2.5 to 3.5; Make wind tunnel wind energy density increase substantially; Adopt aperture formula volume damper, when ambient wind velocity is lower than 1m/s, the work of wind-force air blower of compensating; Make the interior wind speed of wind-tunnel reach 42m/s, promptly start wind speed.When ambient wind velocity reached 2.5m/s, the work of wind-force air blower of compensating quit work, and the wind speed that aperture formula volume damper exhaust outlet ejects swirling eddy reaches 250m/s.Swirling eddy blows on the wind wheel blade back, is the inaccessible lift of existing wind-powered electricity generation wind wheel blade in service, and in the prior art, the wind-powered electricity generation wind wheel blade is vertical with wind direction.And the generating wind-tunnel of the utility model is plunderred area unit generated output at identical wind wheel wind and is risen to hundred MW class by several megawatts; Realized fully in the low wind energy density of surrounding city zone; Using wind-power electricity generation is urban electricity supply directly with 10KV, has removed the burden of the remote transmission & distribution of wind energy turbine set wind-power electricity generation from.
