The direction of piece) it is arranged, in the space that the first rotating plate and the second rotating plate are formed, heat focus is focused on by wind-powered electricity generation leaf by concave mirror
On piece, to not only can during processing focus on the heat of sunlight infrared ray on wind electricity blade, simultaneously because from hot wind
The heat that the hot wind that nozzle sprays is had can also be focused on heat on wind electricity blade by the concave mirror of both direction, thus by force
Change the utilization rate of heat, avoids unnecessary thermal loss as far as possible.
On the mixed vapour and hot wind mixed injection to blade formed by setting pure water and alcohol mixeding liquid body, due to
Vapor and alcohol vapour are changed into liquid by gaseous state pre-cooling and are required to discharge a large amount of heat, therefore physical state in this way
Variation is so that blade surface obtains relatively large number of heat, to substantially increase blade deicing efficiency.And due to the ice of ethyl alcohol
Point is very low, and the blowing and condensation of certain time can form certain ethyl alcohol film in blade outer surface, even and if such ethyl alcohol film
Short-term presence, which also can freeze again to blade surface, causes certain obstruction, to reduce the possibility that blade freezes again
Property.Simultaneously because ethyl alcohol gasification temperature is low compared with water, thus mixed vapour during rise in component can it is few as far as possible
The parts surface of blades condenses, so that more steam is changed into liquid after reaching blade surface as far as possible, thus

By the way that the second blower is arranged, after third blower extracts gas to pylon inside, pass through during moving up
Heating element heats gas, and the second blower inverts during beginning, is vented from the top down, thus by gas heating zone
The pressure that gas in domain flows up reduces, so that air pressure increases in the region, so that gas flow rate from bottom to top is significantly
It reduces, so that gas degree of heat greatly improves, so that reaching 90 ~ 105 DEG C of left sides from the gas temperature that hot-blast spray nozzle sprays
It is right.
It is periodically rotated and reverse by the way that the second blower is arranged, when reversion, thus sprayed in hot-blast spray nozzle
Hot blast rate is very small, and not spraying as far as possible guarantees the temperature of gas, and when the second blower rotates forward, gas heating zone
Interior air pressure abrupt release, thus the rotation of cooperation the second blower and the first blower, the flow velocity of the hot wind sprayed from hot-blast spray nozzle
It is relatively high, so as to rapidly contact hot wind with wind electricity blade, enhances hot wind and exchanged with the heat of wind electricity blade, also kept away
The unnecessary loss of heat is exempted from.
The heating element of the liquid such as pure water and ethyl alcohol is set below Hot-blast Heating region, and the steam after heating evaporation is suitable
Pylon move up, contacted at hot-blast spray nozzle position with hot wind, hot wind carries spraying by hot-blast spray nozzle for steam pulsed
To wind electricity blade, so that hot wind is sufficiently mixed with steam, what the heat exchange and steam condensation that hot wind is adequately utilized discharged
Dual heat, while hot wind high speed being cooperated more efficiently to remove the ice sheet of wind electricity blade outer surface with the heat of blade collision
It goes.
By the way that the first rotating plate and the second rotating plate that can be rotated up is arranged, wind electricity blade to be processed is included at one
In region, the effect so as to which the heat in the region is played a heat preservation (as a further preference, can be first
Rotating plate and the second rotating plate edge-perpendicular are provided with the rubber strip of solid matter, and the face of heat blocking is further arranged from side), at this
