Abstract
Relating to the wind-generated power equipment, the utility model discloses a cabin anti-corrosion system for a wind generating set on sea or in intertidal zones. The system is provided with a dehumidification and filter device at a designated air intake in the cabin. The other parts with gaps except the designated air intake are relatively sealed or are provided with an air passageway independent of the cabin environment, therefore, forming a relatively sealed space. The air entering the cabin through the designated air intake undergoes dehumidification and the entering particles with measurable diameters are filtered. By controlling the humidity, the salt mist as well as the air flow in the cabin, the cabin is full of relatively drier and purer air that has already been dehumidified and desalted, which creates a micro-positive pressure. The micro-positive pressure ensures that the components and parts in the cabin work in an air environment similar to that on the land, therefore, minimizing to the largest extent the corrosion effects of the humidity and salt mist on the sea to the working components in the cabin. The whole anti-corrosion system only requires partial modifications to the structure and takes a lower cost to build. Further, the anti-corrosion system is simple to be carried out and is quite reliable. The technological solution itself is not so demanding therefore making easy maintenance possible.

The at present domestic method that mainly adopts aspect anticorrosion is: the anticorrosion grade that improves component; Improve the thickness of insulation class or raising corrosion-inhibiting coating.These methods are the cost height comparatively speaking, and reliability is low.At sea or following problem can occur during the installation and operation of intertidal zone:
1. high humility in the atmosphere and high salt fog have very strong corrosion to the component of unit, and corrosion-inhibiting coating was limited to 15 years in the longest anticorrosion year, did not reach 20 years design periods of wind-powered electricity generation unit.
2. because the manufacturing process problem is easy to generate some slits, in case the crevice corrosion generation has been arranged, anticorrosive coat is then powerless, the very fast meeting of component damages because of corrosion or and shortens the life-span.
3. though improved anticorrosion grade, but electronic parts and components are worked under the environment of high salt fog, high humility for a long time, and the surface can form the salt fog particle, form thin film on the electronic parts and components surface after the moisture absorption, cause the electrical apparatus element bad connection easily, danger such as corrosion short circuit; Component of machine causes surface or surface of contact corrosion equally easily, causes mechanical failure.
4. each component is improved anticorrosion grade or use grade peculiar to vessel can cause the significantly lifting of cost and complicated operation.
At present existing a kind of salt grain that prevents to have corrosive action infiltrates the device of offshore wind energy facility, this device utilizes the air pressure generating means to produce forced air, and air is incorporated in the sealed mode zone separates by centrifugal force, make water or salt grain be deposited on outer ledge, be removed then.
This method efficient is lower, and reliability is not high, i.e. the difficult control of air quality, thus do not reach good antiseptic effect.By forced air centrifugal force water is separated with the salt grain relatively, the speed height can fall more water and salt fog, but high velocity air can be taken away part moisture content and salt grain then; Speed is low, can remove and not fall the water and the salt fog particle of larger particles, thereby not reach the air quality of setting at designated space.
This method requires high to equipment in addition.Reach the effect that water or salt grain throw away, must make air-flow produce higher speed, like this, can have relatively high expectations to the air pressure generating means, and high velocity air need be by there being the long passage of bend, seal to passage has high requirements, otherwise the meeting pressure release, these all can exert an influence to the reliability of this device.
Summary of the invention:
The utility model is intended to eliminate many unfavorable factors of existing anticorrosion scheme, and improving design realizes cost efficiency.Dominant ideas of the present utility model are:
In the cabin, specify the intake grill position that dehumidifying and filtrating equipment are installed, the measure of the wind passage of cabin atmosphere is taked to seal relatively or be independent of in other positions, slit except that specifying intake grill, cabin, form a relative sealed space.
To dehumidifying and the certain diameter particulate filtration from the air of specifying intake grill to enter in the cabin, by humidity to appointment intake grill air intake in the cabin, the control of salt fog and flow, make the dehumidifying and desalination after relatively dry and pure air be full of whole cabin, and form phase micro positive pressure to external world, thereby allow in the cabin component under the environment of a similar land air, work, reduced the corrosion of marine humidity and salt fog to greatest extent, to guarantee the proper functioning and the corresponding life-span of component in the cabin to it.
Cabin dehumidifying desalination corrosion protection system described in the utility model can be controlled the environment in a space, carry out anticorrosion from integral body, only need improve, not need each independent component are improved requirement for anticorrosion, especially electric components partial structurtes, saved cost greatly, guarantee the working life of component and complete machine, and implemented simply the reliability height, the technical requirements of equipment own is not high, the whole system easy care.
