HTF-B型斜流消防排煙風(fēng)機(jī)用于有消防要求的建筑物如地鐵逐道高層建筑體育管地下商場(chǎng)等場(chǎng)合的消防排煙和通風(fēng)換氣。一般采用雙速電機(jī),平時(shí)低速運(yùn)行做通風(fēng)換氣用,如一旦發(fā)生火災(zāi),通過(guò)電控系統(tǒng)自動(dòng)切換成高速運(yùn)行,在半小時(shí)內(nèi)迅速排除煙氣,使火場(chǎng)內(nèi)人員安全撤離,保護(hù)國(guó)家和人民的生命財(cái)產(chǎn)安全。輸送空氣和其他不自燃、對(duì)鋼材無(wú)腐蝕性報(bào)體,氣體內(nèi)不允許有粘性物質(zhì)。所含的塵土及硬質(zhì)顆粒物不大于150mg/m3,作通風(fēng)換氣用時(shí)進(jìn)氣氣溫度不得超過(guò)80度,作消防用時(shí),煙氣溫度在280度時(shí)能連續(xù)運(yùn)行30分鐘以上。
Htf-b diagonal flow fire smoke exhaust fan is used for fire smoke exhaust and ventilation in buildings with fire protection requirements, such as subway, high-rise buildings, sports pipes, underground shopping malls and so on. Generally, the two speed motor is used for ventilation at low speed. In case of fire, it will be automatically switched to high-speed operation through the electric control system to quickly remove the smoke within half an hour, so as to make the personnel in the fire site evacuate safely and protect the life and property safety of the state and people. Conveying air and other non spontaneous combustion and non corrosive newspapers to steel, and viscous substances are not allowed in the gas. The dust and hard particles contained shall not be greater than 150mg / m 3, When used for ventilation, the inlet air temperature shall not exceed 80 ° C. when used for fire fighting, the flue gas temperature can run continuously for more than 30 minutes when it is 280 ° C.
