Abstract
The invention discloses a low-noise diesel generating set. The low-noise diesel generating set comprises a box body and a diesel generating set. Innovation points comprise that air inlets and air outlets are formed in the box body; the air inlets are formed in the top surface and the bottom surface of the box body on one side of an electric generator; the air outlets are formed in the top surface and the bottom surface of the box body on one side of a diesel engine; an air inlet silencing area, a set arrangement area, a smoke discharging pipeline silencing area and an air exhaust silencing area are arranged inside the box body; the set arrangement area is arranged at a central position at the bottom on the internal side of the box body; the smoke discharging pipeline silencing area is arranged above the set arrangement area; a silencer is connected to the smoke discharging pipeline; the air inlet silencing area is arranged at an electric generator end of the diesel generating set; an air inlet silencing plate is arranged inside the air inlet silencing area; the air exhaust silencing area is arranged at a diesel engine end of the diesel generating set; an air exhaust silencing baffle plate is arranged inside the air exhaust silencing area. The low-noise diesel generating set achieves the purpose of reducing noise due to comprehensively utilization of technologies of sound insulation and sound absorption and is simple in structure and obvious in noise reducing effect.
Description
Technical field
The present invention relates to a kind of diesel generating set, be specifically related to a kind of diesel generating set of low noise.
Background technique
Diesel generating set take diesel engine as prime mover, drags a kind of power apparatus of synchronous generator generating.Diesel generating set starts rapidly, operation and maintenance convenience, little investment, the electricity generating device stronger to the conformability of environment.
Operationally there is the shortcoming that vibrations are large, noise is large in diesel generating set, noise is mainly derived from motor, comprise Explosive noise, fan noise, exhaust sound etc., if do not take necessary noise reduction measure, the noise of unit operation will cause serious harm to surrounding environment.
Summary of the invention
The object of the invention is to for deficiency of the prior art, a kind of low noise diesel generator set of excellent noise reduction effect is provided.
For solving the problems of the technologies described above, in the technology that the present invention adopts, scheme is:
A kind of low noise diesel generator set, comprise casing and diesel generating set, its innovative point is: described casing is provided with intake grill and exhaust outlet, intake grill is arranged at end face and the bottom surface of generator one side box body, exhaust outlet is arranged at end face and the bottom surface of diesel engine one side box body, the madial wall that casing does not arrange intake grill and exhaust outlet is provided with acoustical cotton, and box house arranges air intake noise reduction district, unit arranges district, gas exhaust duct noise reduction district and air draft noise reduction district; Described unit arranges that district is positioned at box inside bottom centre position, and unit arranges that above district be gas exhaust duct noise reduction district, and gas exhaust duct is connected with baffler; Described air intake noise reduction district is positioned at diesel generating set generator end, and air intake noise reduction arranges air intake muffler plate in district; Described air draft noise reduction district is positioned at diesel generating set diesel engine end, and air draft noise reduction arranges air exhausting soundproofing baffle plate in district.
Further, described intake grill and exhaust outlet place arrange grid.
Further, described diesel generating set support bottom is provided with beam.
Further, be provided with air-flow between described air intake muffler plate and casing and separate guide plate, described air-flow separates guide plate and casing is bolted.
Beneficial effect of the present invention: the source that group produces for noise of diesel motor set, rationally carry out casing Noise measarement subregion, and the integrated use technology such as sound insulation, sound absorption reaches the object of noise reduction, and structure of the present invention is simple, and noise reduction is obvious.
