防排煙管道與排風(fēng)管道的裝置規(guī)范不一樣

The device specifications of smoke control duct and exhaust duct are different

①排煙風(fēng)道外外表與木質(zhì)等可燃構(gòu)件的距離不應(yīng)小于15㎝,或在排煙道外外表包厚度不小于10㎝的保溫資料進(jìn)行隔熱。

① The distance between the outer surface of the smoke exhaust duct and wood and other combustible components shall not be less than 15 cm, or the outer surface of the smoke exhaust duct shall be insulated with insulation materials with a thickness of not less than 10 cm.

②排煙風(fēng)道穿過擋煙墻時(shí)，風(fēng)道與擋煙隔墻之間的空地，應(yīng)用水泥砂漿等不燃資料緊密填塞。

② When the smoke exhaust air duct passes through the smoke retaining wall, the open space between the air duct and the smoke retaining wall shall be tightly filled with incombustible materials such as cement mortar.

③排煙風(fēng)道與排煙風(fēng)機(jī)的銜接，宜選用法蘭銜接，或選用不焚燒的軟性銜接。

③ The connection between the smoke exhaust duct and the smoke exhaust fan should be flange connection or non incineration soft connection.

④需要隔熱的金屬排煙道.有必要選用不燃保溫資料，如礦棉、玻璃棉、巖棉、硅酸鋁等資料。

④ Metal exhaust ducts requiring insulation It is necessary to select incombustible insulation materials, such as mineral wool, glass wool, rock wool, aluminum silicate, etc.

⑤煙氣排出口的資料應(yīng)選用耐火性能好的資料制造;排出口的方位應(yīng)依據(jù)建筑物所在的條件確認(rèn)，有必要避開有焚燒風(fēng)險(xiǎn)的部位。

⑤ The data of flue gas outlet shall be made of data with good fire resistance; The orientation of the exhaust outlet shall be determined according to the conditions of the building, and it is necessary to avoid the parts with incineration risk.

排煙的意圖是將室內(nèi)的煙塵通過抽風(fēng)機(jī)械排到室外,而通風(fēng)是能過機(jī)械使室內(nèi)外的空氣進(jìn)行強(qiáng)制流轉(zhuǎn),他們的通風(fēng)方向和地點(diǎn)就是不同的,

The purpose of smoke exhaust is to exhaust the indoor smoke and dust to the outside through the exhaust machinery, and ventilation is to force the air inside and outside the room through the machinery. Firstly, their ventilation direction and location are different,

其次,他們流轉(zhuǎn)的空氣質(zhì)量是不同的,所以不能運(yùn)用同一個(gè)管道,否則,咱們在通風(fēng)時(shí),不小心把煙塵通到室內(nèi),豈不是適得其反.

Secondly, the air quality they circulate is different, so we can't use the same pipe. Otherwise, it would be counterproductive if we inadvertently send smoke and dust indoors during ventilation

排煙管道與排風(fēng)管道的裝置規(guī)范不一樣，排煙管道系統(tǒng)中要裝置排煙防火閥，而一般的排風(fēng)管道不用裝置。

The device specifications of smoke exhaust duct and exhaust duct are different. Smoke exhaust fire damper shall be installed in the smoke exhaust duct system, while the general exhaust duct does not use devices.
