D88尊龙燃氣發電機組由燃氣發動機、發電機、控制柜等部件組成,燃氣發動機與發電機安裝在同一個鋼制底盤上。機組以天然氣、井口伴生氣、煤礦瓦斯氣、水煤氣、煉化尾氣、沼氣、焦爐煤氣、高爐煤氣等可燃性氣體為燃料,啟動迅速,經濟性好,特別是由于高質量城市生活的需求,燃氣發電機組已廣泛應用于電信、郵局、銀行、圖書館、醫院、賓館等部門。

The gas generator is composed of a gas engine, a generator, a control cabinet, etc. the gas engine and the generator are installed on the same steel chassis. Set to Iguchi Banoike, natural gas, coal mine gas, water gas, refinery tail gas, methane gas, coke oven gas, blast furnace gas and other combustible gas as fuel, start quickly, the economy is good, especially because the demand for high quality of life in the city, the gas turbine has been widely used in telecommunications, post office, bank, library, hospital Hotel and other departments.

D88尊龙機組運行時產生的噪聲給城市環境帶來了嚴重的噪聲污染,影響了人們的正常工作和生活,也限制了燃氣發電機組的廣泛應用。針對燃氣發電機組噪聲污染問題,燃氣發電機組廠家的小編提出了一套整改措施,以期降低機組噪聲,促進燃氣發電機組的推廣應用。

The noise generated by the operation of the unit brings serious noise pollution to the urban environment, affects the normal work and life of the people, and limits the wide application of the gas generator set. In order to solve the problem of noise pollution of gas generator set, the paper puts forward a set of measures to reduce the noise of the unit, and promote the popularization and application of gas generator set.

1、聲源分析

D88尊龙燃氣發動機噪聲是燃氣發電機組的主要噪聲來源,燃氣發動機噪聲可分為空氣動力噪聲、燃燒噪聲、機械噪聲、排氣噪聲和振動噪聲。空氣動力噪聲主要包括進、排氣和風扇旋轉引起的空氣振動噪聲,這部分噪聲直接向空氣中傳播。氣缸內燃燒所形成的壓力振動通過缸蓋,機體向外輻射的噪聲叫燃燒噪聲;活塞對缸套的撞擊,配氣機構、噴氣系統等運動部件產生的撞擊振動噪聲統稱為機械噪聲。

D88尊龙Gas engine noise is the main noise source of gas generator set, and the noise of gas engine can be divided into aerodynamic noise, combustion noise, mechanical noise, exhaust noise and vibration noise. The aerodynamic noise mainly includes the air vibration noise caused by the intake, exhaust and fan rotation. The cylinder head vibration by pressure cylinder formed by the body noise radiated noise of the cylinder piston is burning; impact, the impact of vibration noise motion of gas distribution mechanism, jet system and other components are called mechanical noise.

2、改造設計

基于燃氣發電機組的工作原理,難以用降低聲源噪聲的方法來消聲,所以主要是要有效阻斷其噪聲傳播途徑。消聲技術的核心就是利用聲波在傳播中自然衰減的規律去縮小噪聲的污染面。具體降低噪聲的方法有以下幾種:吸聲、隔聲及改變噪聲傳播方向。

Based on the working principle of the gas generator set, it is difficult to use the method to reduce the noise of the noise source, so it is necessary to effectively block the way of noise transmission. The core of the technology is to reduce the noise pollution surface by using the law of natural attenuation of the sound wave. There are several methods to reduce noise, such as sound absorption, sound insulation and noise propagation.
