Description
Technical field:
The present invention relates to wind power plant.
Technical background:
Present stage wind-power electricity generation is developed rapidly in China, and installation amount presents explosive growth.Along with land wind provides
A large amount of exploitations in source and the huge DEVELOPMENT PROSPECT of offshore wind speed, development offshore wind farm is natural.Oversea wind resource
Condition is better than land, and the site that land is suitable to install Wind turbines is limited, but Oversea wind power generation is compared with land wind-power electricity generation
There is many difficulties, the anticorrosion of offshore wind turbine is one of difficult point.
The most domestic method that mainly uses in terms of anticorrosion is: improve the anticorrosion grade of parts；Improve the class of insulation
Or improve the thickness of corrosion-inhibiting coating.These methods cost comparatively speaking is high, and reliability is low.At sea or Intertidal zone installation and operation
Time there will be following problem:
1. the high humility in air and high salt fog have the strongest corrosion to the parts of unit, the longest the preventing of corrosion-inhibiting coating
Corruption is limited to 15 years in year, does not reaches 20 years design periods of Wind turbines.
2. due to manufacturing process problem, easily producing some gaps, once had crevice corrosion generation, anticorrosive coat is the most incompetent
For power, parts quickly can damage because of corrosion or and shorten the life-span.
3. although improve anticorrosion grade, but electronic devices and components working for a long time in the environment of high salt fog, high humility, surface
Salt fog granule can be formed, form thin film after moisture absorption on electronic devices and components surface, easily cause electric elements loose contact, rotten
The danger such as erosion short circuit；Component of machine the most easily causes surface or contact surface corrosion, causes mechanical breakdown.
4. each parts improved anticorrosion grade or use grade peculiar to vessel that cost can be caused to be substantially improved, and operating
Complicated.
The most existing a kind of salt grain preventing from having corrosiveness penetrates into the device of offshore wind energy facility, and this device utilizes gas
Hair Fixer generating apparatus produces forced air, and introduces air in a closed region and separated by centrifugal force, makes water
Or salt grain is deposited on outer ledge, then it is removed.
The method is inefficient, and reliability is the highest, i.e. air quality difficulty controls, thus does not reaches good antiseptic effect.
Relatively being separated water and salt grain by forced air centrifugal force, speed height can fall more water and salt fog, but high speed gas
Stream can take away part moisture content and salt grain then；Speed is low, can remove water and the salt fog granule not falling larger particles, thus specify sky
Between do not reach the air quality of setting.
Additionally the method is high to equipment requirements.The effect that water to be reached or salt grain throw away, it is necessary to make air-flow produce higher
Speed, so, can require higher to pressure generator, and high velocity air needs the longer passage by there being bend, right
The seal of passage has high requirements, otherwise can pressure release, these all can produce impact to the reliability of this device.
Summary of the invention:
It is contemplated that eliminate many unfavorable factors of existing Corrosion prevention scheme, improving design, it is achieved cost efficiency.This
The dominant ideas of invention are:
Specify air inlet position that dehumidifying and defecator are installed in cabin, to cabin other seams in addition to specifying air inlet
Opposing seal or the measure of the wind passage independent of cabin atmosphere are taked in gap position, form the space of an opposing seal.
Dehumidify and the filtration of certain diameter granule, by cabin to from the air specifying air inlet to enter in cabin
The humidity of interior appointment air inlet air intake, salt fog and the control of flow, make the relatively dry after dehumidifying and desalination and pure air
It is full of whole cabin, and forms phase pressure-fired to external world, thus allow the parts in cabin can be similar land at one
Work in the environment of air, decrease the marine moist and salt fog corrosion to it to greatest extent, to ensure parts in cabin
Normal work and the corresponding life-span.
Cabin of the present invention dehumidifying desalination corrosion protection system can control the environment in a space, prevents from entirety
Rotten, it is only necessary to partial structurtes are improved, it is not necessary to individually each parts to be improved requirement for anticorrosion, the most electrically
Parts, are greatly saved cost, it is ensured that parts and the service life of complete machine, and implement simple, and reliability is high, equipment
Technology own is less demanding, whole system easy care.
Accompanying drawing illustrates:
Accompanying drawing is the cabin dehumidifying desalination pressure-fired system air intake figure of wind power generating set
Detailed description of the invention:
Below in conjunction with accompanying drawing, the invention will be further described.
In cabin, desalination dehumidifying air inlet system figure is as shown in drawings；
Desalination dehumidifying air inlet system is positioned at rear end, cabin, electromotor and gear-box cooler and all establishes relatively independent wind
Passage, all takes the measure of opposing seal with impeller junction and cabin with pylon junction in cabin, is formed in making cabin
The space of one opposing seal.
At the desalination dehydrating unit that air inlet is set up, by the dehumidification by condensation to air and to the air themperature entering cabin
It is controlled by condensing unit and heater, it is ensured that the air in entrance cabin is in suitable temperature range, so that it is guaranteed that machine
High temperature or the water thin film being condensed out in metal surface is not had in cabin.In desalination dehydrating unit, increase filter element simultaneously,
By setting certain filter diameter, salt fog is filtered.
Ambient atmosphere, by specifying desalination dehydrating unit air inlet air intake, filters laggard through coarse filtration, dehumidification by condensation, essence
Enter cabin, it is ensured that enter the humidity of air in cabin and salt fog amount in wind generating set engine room the corrosion threshold of parts with
Under, make relatively dry and pure air be full of whole cabin.
The intake of desalination dehydrating unit is by calculating plus certain surplus cabin internal leakage, and sets up pressure
Gap sensor adjusts the charge flow rate of desalination dehydrating unit, it is ensured that engine room inside remains dynamic pressure-fired shape the most to external world
State, thus the quality of air in ensureing cabin, simultaneously, it is ensured that a certain amount of leakage, to keep the thermal balance in cabin.
When desalination dehumidification system works, environment and air-flow in cabin move towards as shown in FIG., it is ensured that wind-power electricity generation
Machine cabin humidity and salt fog reach designated value, thus meet wind turbine cabin inner components operating environment requirements, maximum
Limit decrease the marine moist and salt fog corrosion to it.
Above-mentioned cabin dehumidifying desalination pressure-fired system can also be any part of wind power generating set, such as pylon, machine
Cabin, impeller, as a relatively independent space, are being specified air inlet to install filtering, dehumidifying device, are being filtered by outside air
Enter this relatively independent space with dehumidifying, and form a dynamically balanced pressure-fired system, reach the antiseptic effect in whole space.
The anticorrosion being carried out wind power generating set by above method all should belong to this patent protection domain.
It addition, for the dehumidifying part of dehumidification by condensation defecator in cabin dehumidifying desalination pressure-fired system, except with
Outside dehumidification by condensation, it is also possible to reach the effect of dehumidifying with physics dehumidifying or heating and dehumidification.Also this patent protection domain should be belonged to.
