【摘要】：以方型格柵和U型方通這兩種常見的通透性吊頂和常見噴頭及布置方式為對(duì)象,研究格柵吊頂對(duì)噴頭滅火性能及現(xiàn)場(chǎng)煙氣的影響。調(diào)整噴頭類型、數(shù)量、距頂棚的位置,設(shè)置4個(gè)工況進(jìn)行分析,得出各工況的滅火時(shí)間、溫度分布。研究表明,使用同樣的格柵時(shí),下垂型噴頭較直立型滅火性能好;當(dāng)設(shè)置高度一定時(shí),噴頭設(shè)置在格柵下方的滅火效果較上方好;當(dāng)設(shè)置同樣的下垂式噴頭時(shí),方型格柵吊頂對(duì)滅火效果影響較大。
[Abstract]:The influence of grid ceiling on fire extinguishing performance and on-site flue gas of square grid and U-type square pass are studied in this paper, which are two common permeability ceilings and common sprinklers and their arrangement. Adjust the type, quantity and position of sprinkler head from the roof, set up four working conditions to analyze, and obtain the fire extinguishing time and temperature distribution of each working condition. The results show that the vertical sprinkler has better fire extinguishing performance than the vertical sprinkler when the same grille is used, the fire extinguishing effect of the sprinkler set below the grid is better when the setting height is fixed, and when the same drooping sprinkler is set, the square grid ceiling has a great influence on the fire extinguishing effect.
