一風(fēng)冷發(fā)電機(jī)房的通風(fēng)系統(tǒng)歸納起來有四套系統(tǒng)
The ventilation system of an air-cooled generator room can be summarized as four systems
平時(shí)通風(fēng)系統(tǒng)
Regular ventilation system
柴油發(fā)電機(jī)組組房通風(fēng)換氣用,就是一般10~15次換氣次數(shù)的通風(fēng)量,可僅設(shè)排風(fēng)機(jī) 如果給排水有氣體滅火,這套系統(tǒng)還要承擔(dān)滅火完畢后的排風(fēng)系統(tǒng)。
The ventilation and ventilation system for diesel generator set rooms is usually 10-15 ventilation times, and can only be equipped with exhaust fans. If there is gas in the water supply and drainage system to extinguish the fire, this system also needs to bear the exhaust system after the fire is extinguished.
發(fā)電機(jī)組發(fā)電機(jī)工藝進(jìn)排風(fēng)系統(tǒng)
Generator process air intake and exhaust system for generator sets
電機(jī)本身有個(gè)很大的排風(fēng)管,這個(gè)是發(fā)電機(jī)自帶的,我們配合提一個(gè)風(fēng)井就可以,同時(shí)設(shè)計(jì)進(jìn)風(fēng)系統(tǒng)補(bǔ)充排風(fēng)量和發(fā)電機(jī)組燃燒空氣量(電氣提資),設(shè)送風(fēng)機(jī),此系統(tǒng)風(fēng)量很大。
The motor itself has a large exhaust duct, which comes with the generator itself. We can cooperate with the installation of an air shaft, and at the same time, design an air intake system to supplement the exhaust air volume and the combustion air volume of the generator set (electrical supply). Install a supply fan, which has a large air volume in this system.
這一套系統(tǒng)也有設(shè)計(jì)是預(yù)留風(fēng)井而已,與發(fā)電機(jī)報(bào)價(jià)無關(guān)。
This system is also designed as a reserved air shaft and is not related to the generator quotation.
柴油發(fā)電機(jī)組發(fā)電機(jī)排廢氣系統(tǒng)
Diesel generator generator exhaust system
牽涉到環(huán)保問題,通常稱之為“排煙管”,發(fā)電機(jī)自帶,電氣的標(biāo)準(zhǔn)圖集上還設(shè)專門給這個(gè)系統(tǒng)設(shè)一個(gè)井,實(shí)際上工程設(shè)計(jì)建筑很難有這么多空地。多半是由發(fā)電機(jī)排風(fēng)井排出室外 ,還有不明白的問題可以直接聯(lián)系發(fā)電機(jī)廠家。
It involves environmental protection issues, commonly referred to as "smoke exhaust pipes". The generator comes with it, and the electrical standard atlas also has a dedicated well for this system. In fact, it is difficult for engineering design buildings to have so much open space. Most likely, it is discharged from the outdoor through the generator exhaust shaft. If you have any questions, you can directly contact the generator manufacturer.
儲(chǔ)油間排風(fēng)系統(tǒng)
Oil storage room exhaust system
可以與1合用,此時(shí)通往儲(chǔ)油間的支管上設(shè)止回閥防火閥;也可以單獨(dú)設(shè)系統(tǒng),采用防爆通風(fēng)機(jī)。
It can be used in conjunction with 1, and a check valve and fire damper are installed on the branch pipe leading to the oil storage room; Alternatively, a separate system can be installed using explosion-proof ventilation fans.
二柴油發(fā)電機(jī)組房通風(fēng)包括兩部分,平時(shí)通風(fēng)和工作通風(fēng)。
The ventilation of the diesel generator set room includes two parts: regular ventilation and working ventilation.
平時(shí)通風(fēng):風(fēng)冷和水冷發(fā)電機(jī)的機(jī)房平時(shí)通風(fēng)取6次換氣次數(shù),儲(chǔ)油間通風(fēng)換氣次數(shù)不小于3次。對(duì)于采用氣體滅火系統(tǒng)的機(jī)房,在火災(zāi)后,本通風(fēng)系統(tǒng)負(fù)責(zé)排除室內(nèi)廢氣,但不是事故通風(fēng)。
Daily ventilation: The machine rooms of air-cooled and water-cooled generators should have 6 ventilation changes, and the ventilation changes in the oil storage room should not be less than 3 times. For computer rooms using gas fire extinguishing systems, this ventilation system is responsible for removing indoor exhaust gases after a fire, but it is not accident ventilation.
工作通風(fēng):柴油發(fā)電機(jī)組須考慮工作耗氧所需空氣量;風(fēng)冷發(fā)電機(jī)冷卻風(fēng)量大,一般采用自然進(jìn)風(fēng),柴油發(fā)動(dòng)機(jī)自帶風(fēng)扇壓力排放,但250kw柴油發(fā)電機(jī)組自帶風(fēng)機(jī)壓頭只有150Pa左右,在井道阻力大時(shí)需增加風(fēng)機(jī)克服井道阻力,一般進(jìn)風(fēng)井阻力大,加進(jìn)風(fēng)機(jī);排風(fēng)井阻力大,則加排風(fēng)機(jī)。
Working ventilation: The diesel generator set must consider the amount of air required for working oxygen consumption; The air-cooled generator has a large cooling air volume and generally adopts natural air intake. The diesel engine comes with a fan for pressure discharge, but the 250kw diesel generator set comes with a fan pressure head of only about 150Pa. When the shaft resistance is high, a fan needs to be added to overcome the shaft resistance. Generally, when the shaft resistance is high, an inlet fan needs to be added; If the resistance of the exhaust shaft is high, an exhaust fan should be added.
柴油發(fā)電機(jī)組房采用氣體滅火,進(jìn)排風(fēng)通道上應(yīng)設(shè)電磁閥,在250kw柴油發(fā)電機(jī)組房發(fā)生火災(zāi)氣體滅火啟動(dòng)時(shí),連鎖關(guān)閉這些閥門,以保證滅火效果。
The diesel generator room adopts gas fire extinguishing, and electromagnetic valves should be installed on the inlet and exhaust channels. When a fire occurs in the 250kw diesel generator room and gas fire extinguishing is activated, these valves should be interlocked and closed to ensure the fire extinguishing effect.
柴油發(fā)電機(jī)組排煙為有壓排煙,煙氣溫度高,氣流速度高,煙氣需高空排放,煙管應(yīng)考慮保溫隔熱,同時(shí)需設(shè)減震吊架。
The smoke exhaust of diesel generator sets is pressurized smoke exhaust, with high smoke temperature and airflow speed. The smoke needs to be discharged from high altitude, and the smoke pipe should be considered for thermal insulation, and shock absorption hangers should be installed.
