Embodiment
Further specify technological scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
The principle of patent of the present invention is that implementation structure is simplified, the effect that comprehensive utilization rate of systems improves through combining heat-exchange system and ventilation filtration system.
As shown in Figure 1, heat-exchanger rig 4 is connected to form heat transferring medium through pump group 3 and heat-producing device 2 closed cycle is filtered in the ventilation that is arranged in the engine room cover 1; Wherein, Pump group 3 guarantees that heat transferring medium filters the closed cycle between the heat-exchanger rig 4 at heat-producing device 2 and ventilation; Air after filtering heat-exchanger rig 4 purifications through ventilating and participating in heat exchange gets in the cabin, and the hole of folding reason size on engine room cover 1 can guarantee to realize in the cabin malleation effect; Prevent that under the wind effect salt fog particle gets in the cabin.Get into air clean relatively in the cabin simultaneously; Mix with air in the cabin; Regulate environment in the cabin; Especially in the winter time, be higher than the temperature cabin at this moment through the gas temperature that ventilate to filter heat-exchanger rig 4 heat radiations, can be after in the air entering cabin of filtering heat-exchanger rig 4 to the cabin through ventilating in integrated environment play heat effect.
Like Fig. 1,2, shown in 3; Heat-exchanger rig 4 is filtered in the marine ventilation with wind power generating set of the present invention; Comprise heat exchanger and filter box 4-5; Wherein heat exchanger is made up of induced draught fan 4-1 and plate and fin type heat radiating fin structure 4-2, and plate and fin type heat radiating fin structure 4-2 is connected to form the closed cycle of heat transferring medium through pump group 3 and heat-producing device 2; The ingress of filter box 4-5 is provided with steam-water separator 4-9; And the multi-layer air filtering core that in filter box 4-5, behind the steam-water separator 4-9, is provided with different brackets (is just imitated air-filtering core body 4-8; Middle air-filtering core body 4-7, the high-efficiency air filtering core body 4-6 of imitating); Filter box 4-5 is arranged on the air-cooled inlet side (bottom) of the plate and fin type heat radiating fin structure 4-2 of heat exchanger, and induced draught fan 4-1 is arranged on the opposite side of plate and fin type heat radiating fin structure 4-2.
Marine air is the steam-water separator 4-9 in elder generation's process filter box 4-5 under the effect of induced draught fan 4-1; Drop in the certain limit in the maritime environment and salt fog composition are wherein removed, and air (is just imitated air-filtering core body 4-8, middle effect air-filtering core body 4-7 through the air-filtering core body then; High-efficiency air filtering core body 4-6); Further the salt fog of variable grain degree in the air is removed, for the filtration grade of air-filtering core body and the number of plies is set can carries out actual setting according to the on-site maritime environment situation of wind-powered electricity generation unit, the gas that purifies through the air-filtering core body gets into plate and fin type heat radiating fin structure 4-2; Heat transferring medium in the plate and fin type heat radiating fin structure 4-2 cools off; Get into then in the cabin,, discharge through the opening that is provided with on the engine room cover 1 with the air mixing in the cabin.
For the ease of detecting the validity of air-filtering core body; All arrange pressure transducer (Pressure probe) 4-4 in both sides up and down at each layer of air filtering core, and the pressure difference sensing equipment 4-3 that is connected with each pressure transducer (Pressure probe) 4-4 is arranged in filter box 4-5 arranged outside.Through gathering; Pressure transducer (Pressure probe) 4-4 passes to pressure difference sensing equipment 4-3 with signal; Feed back the formed resistance of each layer of air filtering core; After certain layer of air filtering core resistance reached whole resistance, pressure sensing device 4-3 reported to the police, and needed the air-filtering core body is cleaned or changes.
Replacing for the ease of the air-filtering core body; Steam-water separator 4-9, just imitate air-filtering core body 4-8; Middle effect air-filtering core body 4-7 and high-efficiency air filtering core body 4-6 fix through the draw-in groove structure in filter box 4-5, and the side of filter box 4-5 is provided with access door 4-10, opens access door 4-10; Can directly steam-water separator 4-9 and air-filtering core body be extracted out in filter box 4-5, it is cleaned or changes.
For the air-filtering core body number of plies and grade can be according to concrete ambient conditions setting, only represented the schematic representation of the three-stage filtration situation of primarily efficient filter, medium air filtration, high efficiency filter among Fig. 2, Fig. 3.
To sum up, the embodiment of the invention is simplified structure fully, raises the efficiency; Through combining with heat exchanger and filtration system; Not only can save a cover induced draught fan structure, can improve the ageing of heat exchanger performance simultaneously, and can utilize the air that gets in the cabin that the environment in the cabin is carried out suitable adjusting.
The above; Be merely the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, anyly is familiar with this technological people in the technical scope that the present invention disclosed; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
