During the working process of the generator set, a small amount of waste and small solid particles are produced, and the main harm is noise. Its sound value is about 108 dB, which seriously affects people's normal work and life.

發(fā)電機(jī)組房消音環(huán)保工程需要根據(jù)機(jī)房的具體情況進(jìn)行設(shè)計(jì)和施工。為了保障機(jī)組的正常工作，在設(shè)計(jì)發(fā)電機(jī)組房消音工程時(shí)，需要注意以下幾個(gè)方面:

The noise elimination and environmental protection project of generator set room needs to be designed and constructed according to the specific conditions of the machine room. In order to ensure the normal operation of the unit, the following aspects should be paid attention to when designing the silencing project of generator set room:

1.系統(tǒng):機(jī)房內(nèi)不得設(shè)置燃油箱，不得堆放易燃易爆物品、要配置消防器材.同時(shí)，井聯(lián)電柜等電氣設(shè)備要與發(fā)電機(jī)組房隔離開來，以免影響電氣元件的工作壽命。

1. System: fuel tank shall not be set in the machine room, inflammable and explosive articles shall not be stacked, and fire-fighting equipment shall be equipped At the same time, electrical equipment such as well connection cabinet shall be isolated from the generator set room to avoid affecting the working life of electrical components.

2.進(jìn)風(fēng)系統(tǒng):每臺(tái)發(fā)電機(jī)組工作時(shí)需要大量的新鮮空氣,所以機(jī)房有足夠的進(jìn)風(fēng)。

2. Air inlet system: each generator unit needs a lot of fresh air during operation, so there is enough air inlet in the machine room.

3.排風(fēng)系統(tǒng):發(fā)電機(jī)組工作時(shí)，鏟生大量的熱量，為便發(fā)電機(jī)組能正常工作,機(jī)房環(huán)境溫度不得超過50握氏度，而對(duì)柴油機(jī)奧好的工況來說，機(jī)房環(huán)境溫度應(yīng)低于37.8攝氏度， 所經(jīng)要抽部分熱量出機(jī)房。發(fā)電機(jī)組房隔音工程的主要內(nèi)容:

3. Exhaust system: when the generator set is working, it generates a lot of heat. In order to make the generator set work normally, the ambient temperature of the machine room shall not exceed 50 ° C. for the excellent working condition of the diesel engine, the ambient temperature of the machine room shall be lower than 37.8 ° C, and part of the heat shall be pumped out of the machine room. Main contents of sound insulation works of generator set room:

1.機(jī)房出入通道的隔音:本著方便發(fā)電機(jī)組調(diào)入、調(diào)出及機(jī)房人員工作方便的原則來設(shè)置-個(gè)或二個(gè)隔音門，以金屬構(gòu)架，內(nèi)附高質(zhì)量隔音材料,度以8cm至12cm為宜.

1. Sound insulation of the entrance and exit of the machine room: one or two sound insulation doors shall be set in the principle of facilitating the transfer in and out of the generator set and the work of the machine room personnel. They shall be metal frame with high-quality sound insulation materials inside, and the degree shall be 8cm to 12cm

2.進(jìn)風(fēng)系統(tǒng)的隔音:在進(jìn)風(fēng)面設(shè)置消音槽和隔音墻，采取強(qiáng)制進(jìn)風(fēng)方式以保持機(jī)組正常運(yùn)行所需的新鮮空氣。

2. Sound insulation of air inlet system: set silencing trough and sound insulation wall on the air inlet surface, and adopt forced air inlet mode to maintain fresh air required for normal operation of the unit.

3.排風(fēng)系統(tǒng)的隔音。在排風(fēng)面沒置消音槽和隔音墻，采取強(qiáng)制排風(fēng)方式，以更大的限度降低發(fā)電機(jī)工作環(huán)境溫度。

3. Sound insulation of exhaust system. There is no silencing slot and sound insulation wall on the exhaust surface, and the forced exhaust mode is adopted to reduce the working ambient temperature of the generator to a greater extent.

4.煙道消聲系統(tǒng):在機(jī)房外的煙管上安裝級(jí)阻尼式消音哭器，以降低發(fā)動(dòng)機(jī)排煙噪聲,同時(shí)又要不影響廢氣的排放。

4. Flue silencing system: stage damping silencers are installed on the smoke pipes outside the machine room to reduce the exhaust noise of the engine without affecting the emission of exhaust gas.

5.吸音墻和吸音天花,在機(jī)房內(nèi)寺上安裝吸盤音材料，以防止境音從機(jī)房頂傳出和回彈，降低室噪音分貝數(shù)。

5. For the sound-absorbing wall and ceiling, install sound-absorbing materials on the temple in the machine room to prevent the ambient sound from coming out and rebounding from the roof of the machine room and reduce the decibel of room noise.
