Description
Technical field
The utility model relates to a kind of transformer station matching component, particularly a kind of transformer station sound-proof ventilation unit.
Background technology
A lot of equipment of transformer station all need periodical blowdown, and water higher for the salt concentration of deposition is drained, and the medium at this moment in high-pressure bottle enters low pressure vessel fast by valve and just easily produces noise.
Along with the change exhibition of society, the raising that present people require quality of life, more and more payes attention to for noise pollution; And existing market does not have specific aim product, make the staff in standing and transformer station surrounding area extensively be subject to noise pollution.
Utility model content
Change improving eyesight: for the deficiencies in the prior art, the utility model discloses a kind of transformer station sound-proof ventilation unit.
Technical scheme: the utility model discloses a kind of transformer station sound-proof ventilation unit, comprises the blast pipe, low-noise fan, ventilation duct and the sound arrester that connect successively; Described blast pipe comprises tube wall, lays sound absorbing layer inside tube wall; Described ventilation duct comprises tube wall, lays sound absorbing layer inside tube wall; Described sound arrester comprises gas pipe, is arranged on the shock absorber of gas pipe upper end, and shock absorber upper end is provided with air outlet; Described shock absorber comprises housing, vertically arranges one group of abatvoix in housing; Described sound arrester is vertically arranged; Described sound arrester top is provided with rainhat.
Wherein, described blast pipe tube wall is the galvanized pipe of inner side plastic-blasting.
Wherein, described sound absorbing layer is macromolecule acoustical cotton.
Wherein, described gas pipe is up big and down small horn-like housing.
Wherein, described ventilation duct external diameter is identical with gas pipe lower end external diameter.
Wherein, described shock absorber external diameter is identical with gas pipe upper end external diameter.
During use, equipment is placed in the gas outlet of corresponding transformer station, is guided by low-noise fan, steam by step tracheorrhaphy every, discharge after acoustical cotton sound-absorbing, reduce the propagation of noise.
Beneficial effect: transformer station's sound-proof ventilation unit disclosed in the utility model, structure is simple, effectively can process the noise pollution that transformer station's exhaust produces.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of transformer station's sound-proof ventilation unit.
