Described air inlet is opened in housing bottom, and described gas outlet is opened in case top.
Described steam-water separator, salt spray filter all are removably fixed in the housing.
After adopting such design; The utility model has the following advantages at least: introduce engine room inside after adopting centrifugal fan with moist salt fog air process steam outside the cabin and salt filtration; Make engine room inside be full of through the pure air after filtering; And form pressure-fired with nacelle exterior, external humidification salt fog air can't get into engine room inside, and equipment prevents salt air corrosion in the cabin thereby effectively protect; Improved the service life of equipment in the cabin, but and extensive use at sea or in the engine rooms of wind power generators of coastal waters.
Description of drawings
Above-mentioned only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to specify.
Fig. 1 is the structural representation of a kind of sea of the utility model or coastal waters engine rooms of wind power generators salt filtration ventilation unit.
Fig. 2 is the scheme of installation of a kind of sea of the utility model or coastal waters engine rooms of wind power generators salt filtration ventilation unit.
The specific embodiment
See also shown in Figure 1ly, the utility model sea or coastal waters engine rooms of wind power generators salt filtration ventilation unit 1 mainly are made up of housing 10 and the steam-water separator 11, salt spray filter and the blower fans 14 that removably are fixed in the housing 10.
Wherein, housing 10 bottoms offer air inlet 15, and the top offers gas outlet 16.
Steam-water separator 11 is preferably the water fender of shutter, selects for use the fiberglass material to make, and acid, alkali, salt and multiple oils and the solvent of atmosphere, water and general concentration all had resistivity preferably.A whole set of water fender is made up of framework and some groups of string sheets, and every group of string sheet is some corrugated platings, and with plastic sheath at interval, the stainless steel wire rockbolt connects between sheet and the sheet.Water fender is pressed certain distance assembling, facing the wind and place, air-flow can repeatedly change airflow direction with the waveform shape of shelves water plate when passing through, after air-flow reaches certain speed, be about to airborne miniature water droplet elimination, thereby reach the purpose of dehumidifying.As shown in the figure, the best position of steam-water separator 11 is near air inlet 15 places.
Salt spray filter can be made up of primarily efficient filter layer 12 and medium air filtration layer 13, is installed in successively between the air inlet of steam-water separator 11 and blower fan 14.
Primarily efficient filter layer 12 adopts high-intensity multilayer aluminium alloy hole pattern W type pressing lap structure, and the pressing lap design can change airflow direction, strengthens effective filtration area, increases the dust containing capacity of filter.Primarily efficient filter layer 12 is mainly used in removes airborne big dust particle or large diameter floating foreign material.Consider service life and long-time maintenance cost, design primarily efficient filter layer can clean use repeatedly, is difficult for stopping up and influences result of use.
Medium air filtration layer 13 adopts glass fibres to do filtrate, and the W type fold case structure, and it is big to have an air quantity, and resistance is low, the big characteristics of dust containing capacity, mainly fine solid particle and the airborne salt grain in the filtered air.Medium air filtration layer 13 front end are by the protection of primarily efficient filter layer, corresponding prolongation in the service life of medium air filtration layer generally speaking.
The air inlet and the salt spray filter of blower fan 14 join; Air outlet and gas outlet 16 join; The purpose that is provided with like this is in order to prolong the service life of blower fan 14, makes blower fan 14 in device, be positioned at the end of gas channel, and the air through blower fan 14 is the pure air through filtering.Under with the constant power operation, the total head of centrifugal fan is greater than axial flow blower, and therefore the running status of centrifugal fan will start from equipment long-time running security consideration, the preferred centrifugal fan of the utility model surely in axial flow blower under the regular situation.
Please cooperate and consult wind-driven generator shown in Figure 2, common and mainly comprise cabin 2, pylon 3, wheel hub 4 and blade 5, wherein, cabin 2 is installed in above the pylon 3, and blade 5 is installed on the wheel hub 4, and is connected with cabin 2 through wheel hub 4.The utility model sea or coastal waters engine rooms of wind power generators salt filtration ventilation unit 1 promptly are installed in the afterbody in cabin 2; Cabin 2 afterbodys have air inlet on engine room cover; The air inlet 15 of the utility model is fixed with stainless steel bolt with the engine room cover air inlet openings, between add the sealing damping and handle.
During use, after the power taking, lasting slave is introduced air out of my cabin to this device in the cabin, through multiple filtration, and effective Chalk-dust filtering but also can steam in the air-flow and salt fog effectively be isolated not only.This device is introduced new wind in the cabin, form pressure-fired in the cabin, and outside salt fog can't get into engine room inside, can improve the service life of equipment in the cabin.
Be the air-flow trend among the figure shown in the arrow; As shown in the figure, at first through steam-water separator 11, air-flow can repeatedly change airflow direction with the waveform shape of steam-water separator 11 home record water plates to moist salt fog air-flow; When air velocity is 0.5～3m/s scope; Behind the undulating path through the water fender composition, be about to airborne miniature water droplet elimination, thereby reached the purpose of dehumidifying.
Air-flow continues through primarily efficient filter layer 12.The multilayer aluminium alloy hole pattern W type pressing lap design of primarily efficient filter layer 12 can change through airflow direction, and effective filtration area is strengthened, and increases the filter water environment capacity.Primarily efficient filter layer 12 can filter diameter greater than 5 microns salt fog particles, and filter efficiency reaches 90%.
Air-flow through primarily efficient filter continues through medium air filtration layer 13.This filter course adopts the folding case structure of W type, adopts special glass fibre to do filtrate, mainly filters diameter less than 0.5 micron trickle salt fog particles, and filter efficiency is greater than 95%.
Air through humidity and salt filtration passes through 2 inside, centrifugal fan 14 introducing cabins.Centrifugal fan 14 adopts the 380V three phase supply, and anticorrosion grade reaches the C4 rank of stipulating among the ISO12944.
When wind-driven generator normally moved, the utility model is 2 interior power takings from the cabin, and centrifugal fan 14 operate as normal in it from the nacelle exterior air draught, through introducing 2 inside, cabin behind the multistage filtering, form malleation through the engine room cover air inlet.Pure air escapes into nacelle exterior through installation slits such as engine room cover and tower tube, engine room cover and wheel hubs in the cabin 2, and outside moist salt fog air can't get into engine room inside.Like this, owing to have the pure air environment all the time in the cabin 2, the equipment such as mechanical electric in it have obtained protection, thereby have prolonged working life.On the other hand, introducing new wind and also improved the ventilation and heat situation in the cabin 2, also is favourable to the normal use of various device.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in the protection domain of the utility model.
