Description
Technical field
The present invention relates to a kind of anti-salt fog system, particularly about a kind of salt fog resistant system for wind generating set at sea.
Background technique
Because marine air institute's moisture content and salinity are high, so air is very serious to the erosion of offshore wind generating group.The measure that the anti-salt fog of existing offshore wind generating group corrodes mainly contains: do sealing and installing the sealing hairbrush for mechanical part brush paint, for electronic device, yet the effect of these seal approach is not very good.
Summary of the invention
At the problems referred to above, the purpose of this invention is to provide a kind of effective salt fog resistant system for wind generating set at sea of salt fog easy to install, anti-.
For achieving the above object, the present invention takes following technological scheme: a kind of salt fog resistant system for wind generating set at sea is characterized in that: it comprises an axial-flow blower, a supporting frame, a salt filtration layer, dehumidifying filter layer, a bracket and a bottom bracket; The bottom of the air duct of described axial-flow blower is fixedly connected on the sidewall in generator cabin; The support frame as described above bottom is fastened on the top of the air duct of axial-flow blower; Described bracket and bottom bracket all are fixedly connected on the top of support frame as described above, and described salt filtration layer, dehumidifying filter layer cover the top of support frame as described above respectively under the support of described bracket, bottom bracket.
Described bracket be diameter match with the air duct top of described axial-flow blower ring-like, have a base plate and a riser, described base plate one end is fixed on the support frame as described above, and the other end setting that extends internally constitutes a support part that is used to place described salt filtration layer with described riser.
Described bottom bracket is arranged on the bottom of described bracket, for diameter match with the internal diameter of support frame as described above ring-like; Described bottom bracket has a sidewall, described sidewall upper is provided with an outward extending flange, so that described bottom bracket is fixed on the support frame as described above, the lower end of described sidewall is provided with a supporting plate that extends internally, with the carriage of the described dehumidifying filter layer of described sidewall formation one placement.
Also comprise two contact seal circles, be installed in the joint of described generator cabin and wheel hub and the joint of described wind generating set engine room and tower tube respectively.
The present invention is owing to take above technological scheme, it has the following advantages: 1, the present invention is owing to adopt axial-flow blower to blast air in the cabin, and adopt the mode of salt filtration layer and the combination of moisture filter layer to remove airborne moisture and the salinity that blasts, therefore make the air and the cabin internal air pressure that are full of moisture-free and salinity in the cabin be higher than ambient pressure gradually, have and prevent that ambient air from entering the advantage in cabin.2, therefore the present invention can guarantee the advantage that the air in the cabin is not revealed owing in the junction of cabin and wheel hub and the junction of cabin and tower tube seal ring is installed.The present invention can be widely used in the anti-salt fog operation of offshore wind generating group.

Embodiment
Be described in detail of the present invention below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the present invention is installed on the sidewall in generator cabin 7, comprises an axial-flow blower 1, a supporting frame 2, a salt filtration layer 3, a dehumidifying filter layer 4, a bracket 5, a bottom bracket 6.
Wherein, axial-flow blower 1 has an air duct 11, and the bottom of air duct 11 is connected on the sidewall in generator cabin 7 with bolt, and the sidewall in corresponding generator cabin, air duct 11 bottoms 7 is the open end.
Supporting frame 2 is big or small match with air duct 11 tops of axial-flow blower 1 columnar structured, and the top of supporting frame 2 and bottom are provided with the side edge of outside protrusion, and the side of supporting frame 2 bottoms is continued to use the air duct top that is bolted to axial-flow blower 1.
As shown in Figure 3, the present invention also comprises two contact seal circles 9, two contact seal circles 9 are installed in generator cabin 7 and the joint of wheel hub 10 and the joint of generator cabin 9 and tower tube 12 respectively, leak from each joint to avoid the air in the generator cabin 7.
During use, axial-flow blower 1 is after the electrical network power taking, and the hole that is communicated with by the sidewall with generator cabin 7 blasts air in generator cabin 7, has leached airborne salinity and moisture behind air process salt filtration layer 3 that blasts and the dehumidifying filter layer 4.Axial-flow blower 1 constantly blasts air in wind generating set engine room 7, again because wind generating set engine room 7 adopts contact seal circle 9 to seal with the joint and the generator cabin 7 of wheel hub 10 with the joint of tower tube 12 simultaneously, thereby the air in the assurance wind generating set engine room 7 are not revealed, make the air pressure in the wind generating set engine room 7 be higher than ambient pressure gradually, the then extraneous air that has salinity and moisture can't enter in the wind generating set engine room 7, thereby avoids the erosion of ambient air to wind power generating set.
The embodiment of apparatus of the present invention only is used to illustrate the present invention; wherein the structure of each parts, the position is set and Placement all can change to some extent; every improvement of carrying out on the basis of technical solution of the present invention and equivalents all should not got rid of outside protection scope of the present invention.
