Abstract
The invention relates to noise processing in the field of electric appliances, and discloses a generator room noise processing system. The generator room noise processing system comprises a generator room, wherein a generator set is arranged in the generator room; a noise-reduction air intake system is arranged on one side of the generator room, and a noise-reduction air exhaust system is arranged on the other side of the generator room; an air intake wall and an air exhaust wall are arranged on the generator set. The generator room noise processing system adopts a method in combination of sound insulation, sound absorption, noise reduction, heat insulation and vibration reduction to take comprehensive treatment measures on air power noise, mechanical and electromagnetic noise and solid transmitted noise in the generator room, so as to effectively reduce the environmental noise, well organize the air movement in the generator room, meet airflow rate required by operation of the generator set, ensure the normal operation of the generator set, and avoid secondary noise, the low-carbon material is adopted, which is simple and easy to get and cheap, so that the noise processing cost is greatly lowered, and the value of noise outside the generator room is decreased from the original 108 dB to an enterprise factory boundary daytime noise level which is no more than 65 dB(A).
Description
Technical field
The present invention relates to the noise processed of appliance field, specifically a kind of generator room noise processed system.
Background technology
Along with developing rapidly of China's industry, in recent years, in order to alleviate the contradiction of mains supply deficiency, newly-built diesel power plant or to configure the unit in middle-size and small-size house generator room a lot.Yet the noise of generating set operation will cause serious harm to surrounding environment thereupon.If do not take necessary noise reduction measure, not only reduce productivity effect, also greatly damage the health index of operating personnel and surrounding enviroment biology.Reduce discharging at national energy-saving under the call of green energy conservation, protect and improve environmental quality, diesel-driven generator station noise reduction reduction of discharging project is put into national grid, the daily index that must complete of each generating set producer.
After generator uses, the other integrated noise of unit can reach 105～110dB (A), and the noise of unit exhaust port is about 110～115dB (A).Usually generator room is narrow strip, and width is slightly partially narrow, selectively little while organizing air-flow, and during generator operation, heat radiation requires highly, need fully take into account ventilation; Because machine room is nearer apart from factory circle, require border to reach below 65dB (A) in addition, difficulty of governance is higher; Due to centralized power generation, body is propagated grade acoustic pressure stack of shaking, and acoustic pressure sound level intensity is too high, so eliminate noise structure and take measures to need scientific and reasonable.We should science the understanding noise abatement, and the single subject of can not be only it being regarded as to acoustics studies and uses, otherwise final improvement result will be also to have spent a lot of unjust moneys there is no solving practical problems, even brings other negative effects.
In real work, effectively controlling oil machine noise in machine room is very real and must a solve problem to external radiation.The measures such as the single sound absorption of conventional power generation usage machine room noise abatement process using, noise elimination, do not accomplish and should effectively reduce ambient noise, organize again the Air Flow in machine room, meet the air mass flow of generating set operation needs, to ensure the normal operation of unit.The simple air mass flow that reduces leaking of noise and sacrifice in engine room can cause the oil machine surface cool inhomogeneous, reduces the generate output of oil machine, and impact is normally used.
Summary of the invention
The object of the present invention is to provide a kind of generator room noise processed system.
Purpose of the present invention can be achieved through the following technical solutions:
