The method of operation in the utility model is as follows:
Wind enters from the intake grill of outer narrow pipe 1, because interior narrow pipe 2 integral body by contracting formula are set in outer narrow pipe 1, therefore, reducing by contracting degree of space between outer narrow pipe 1 inner peripheral surface and interior narrow pipe 2 outer circumferential faces, and on the outer circumferential face of interior narrow pipe 2, be provided with tapered sleeve 3, make increasing by contracting degree of space between outer narrow pipe 1 inner peripheral surface and interior narrow pipe 2 outer circumferential faces, thus, wind speed is along with long-pending the dwindling gradually and enhancing gradually of pipeline section in the space between outer narrow pipe 1 inner peripheral surface and interior narrow pipe 2 outer circumferential faces, under the guiding of Windshield 12, wind speed further increases, and adjust after direction through stator 7, impact the blade 51 of impeller 5, thereby concentrated wind energy is converted to the kinetic energy of blade 51, by impeller 5, drive the central shaft of generator 6 to rotate, make generator 6 generatings, lose the wind of most of energy under the wind-guiding effect of rear wind scooper 13, the section of extending out 41 through wake flow pipe 4 is discharged, because air-flow is by the rear formation high velocity air of outer narrow pipe 1, high velocity air flow velocity after promoting blade 51 rotations obviously reduces, therefore at the interior generation wind screen of wake flow pipe 4, now from the intake grill of interior narrow pipe 2, enter the wind in interior narrow pipe 2, after the interior narrow pipe 2 by contracting formula, wind speed strengthens gradually, quick flow in interior narrow pipe 2 can break through wind screen, and drive the Accelerating Removal of the air-flow at a slow speed wake flow pipe 4 in wake flow pipe 4, thereby guarantee the patency of air-flow in whole pipeline, the flow direction of wind is as shown in the direction of arrow in Fig. 2, the exhaust outlet place of the section of extending out 41 of wake flow pipe 4 has further adopted ripple type saw tooth structure, the outside swiftly flowing air-flow of wake flow pipe 4 enters in pipeline from the slot of the section of extending out 41, the relatively slow air-flow of the interior flow velocity of wake flow pipe 4 is accelerated, further promote the discharge of wake flow, reduced thus the pressure at blade 51 back sides, make blade 51 rear portions form low pressure area, because blade face is positive, the pressure difference at the back side increases, at wake flow pipe 4 afterbody peripheries, form negative pressure, make the intake grill of outer narrow pipe 1 and interior narrow pipe 2 can receive more air to enter pipeline.
On the tube wall of narrow pipe 1, along circumference, be provided with and let out air port 18 outside, and control and let out opening of air port 18 by open and close door 8 is set, close, wherein, the form of external door 81 by sliding door is located at lets out 18 outsides, air port, inside door is located at the inner side of letting out air port 18 with the form of stud connection, when in pipe, wind speed is excessive, by control system, detect and send signal, thereby controlling external door 81 traveling priorities and inside door 82 opens and lets out air port 18 to upset in pipe, by letting out the effect in air port 18, air-flow superfluous in pipe is discharged, thereby the wind speed in outer narrow pipe 1 is maintained in the reasonable scope, protection generator 6 nonoverloads, guarantee the continual and steady generating of generator 6, by the setting of the silk 10 of eliminating the noise, can significantly reduce the interior quick flow of pipe from letting out the noise producing when discharge in air port 18.
Under the with serious pollution environment of haze, the dust particles such as PM2.5 are the main matter of atmosphere pollution, also be the good nucleus of condensation, and moisture in atmosphere has absorption, bonding, the function of fixing " particulate ", the utility model is connected with mist device 15 processed by pipeline in the section of extending out 41 of wake flow pipe 4, when utilizing wind-power generating system described in the utility model to carry out after wind-power electricity generation, the green energy that generator 6 is produced is supplied with the mist device 15 processed being connected with the section of extending out 41, mist device 15 processed produces after water smoke, again by pipeline 14, nozzle 16 and the section of extending out 41 are sprayed water smoke in atmosphere, under the coagulation of water smoke, the dust particles such as PM2.5 settle down from air, thereby in the situation that not affecting the manufacturing, effectively reduce diffussion of dust amount, improve Regional Atmospheric Environment, thereby reach the object of falling haze from " basis ", city is installed and is applied the wind-power generating system that haze function falls in mist processed that has described in the utility model, can purify for a long time existing pollution of atmosphere, thereby realize the object of controlling haze from " mark ".The utility model is creatively applied to wind-power generating system fall the air contaminant treatment field of haze, by green energy, oneself supplies with, and with green wind energy control atmosphere pollution, has realized green circulatory, accelerate atmospheric cleaning paces, there is high social benefit and economic benefit.
Described in the utility model have the wind-power generating system that haze function falls in mist processed and also can be applied to other applications such as modern agriculture pesticide spraying, irrigation water sprinkling, mine and construction engineering depositing dust.
More than describing is to explanation of the present utility model, is not the restriction to model utility, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
