摘要：汽车行业已经成为了近几年我国重要的行业之一，然而由于整车制造四大工艺车间所需的工艺要求以及消防设计十分复杂，导致国内的整车制造业时常发生火灾事故。而且一旦发生火灾事故，火势的蔓延极其迅速，对职工的生命造成了巨大的威胁。因此，开展对油漆车间喷房区域火灾烟气蔓延的研究有着重要的意义。62238
本文运用火灾运动软件FDS建立喷房区域的模型，对喷房区域内的火灾进行数值研究。针对火灾产生的烟气，分别采用喷淋系统以及不同位置的机械排烟系统对其加以控制。通过对比室内温度、能见度等相关参数的变化，分析喷房区域内火灾烟气的蔓延规律及相应控制措施的控烟效果，争取找出最佳的方式。

Fire control design of spray room area of automobile paint workshop based on fire simulation
Abstract：Automobile industry has become one of the important industry in China in recent years, however, due to the vehicle four workshops to produce the required process requirements and fire design is very complex, leading to the domestic automobile manufacturing industry frequent fire accidents. And in the event of fire accident, the spread of fire potential is extremely rapid, to the worker's life caused great threat. Therefore, to carry out of paint shop spray room area of fire smoke spread research has important significance.
In this paper, the use of fire software FDS spray room area was established, spray room area of fire numerical simulation was conducted to investigate the. In view of the fire smoke, respectively, using spray system and different positions of the mechanical smoke exhaust system to be controlled. Through comparing with the indoor temperature, visibility and other related parameters change, analysis spray room area of fire smoke spread rules and the corresponding control measures of tobacco control effect, fighting to find the best way.
Key Words：Spray room area; smoke spread; FDS simulation; spray system; mechanical smoke exhaust system
