某会议楼七氟丙烷防火及联动报警设计
摘要:
现代化的办公楼人员相对集中,配套设施经济含量高,因此对消防安全的级别要求较高。此建筑属于高级会议楼(办公楼),根据《建筑防火规范》此楼对消防的安全级别要求为一级,多数使用区域已安装消火栓灭火系统和水喷淋灭火系统,其中一楼的档案室、二楼的微机室和图书馆需要使用气体进行防灭火。分析比较常用的气体灭火物质,介绍七氟丙烷灭火系统的组成及灭火原理。针对此会议楼情况进行了预制式七氟丙烷灭火系统设计,火灾联动报警系统设计以及气体防护区安全疏散的讨论。七氟丙烷灭火剂质量符合国家相应安全的技术标准,故采用预制式全淹没灭火系统,即在规定的时间内,向防护区喷射一定浓度的灭火气体,并使其均匀地充满整个防护区的灭火系统,防护安全高效,故采纳;经过科学实验论证,扑灭火灾的最佳时机属于起火阶段,因此对火灾的报警越早,越容易灭火,能尽最大程度避免火灾带来的损失,使用火灾探测器与人工报警的组合,把信息及时反馈到消防控制中心以便其作出综合判断,实行相关的应急预案,由此可以论证出火灾联动报警系统的重要位置;气体防护区的安全疏散时间为30s,由于灭火剂高温时会产生对人体有害的HF,疏散的实际时间必须小于安全疏散时间,论证设计的合理性,最后经过计算,设计符合国家规范,比较合理。

Heptafluoropropane a conference building fire and Design of linkage alarm
Abstract:The relative concentration of modern office workers, High levels of economic facilities, herefore require a higher level of fire safety. this building is high-level meeting, According to "Building code for fire protection, " the floor level of fire safety requirements for a, Most of the fire hydrant has been installed with the regional water sprinkler systems and fire extinguishing system, The archives of the first floor, second puter room and library need to use gas Fire. Of gas fire extinguishing monly used to introduce the fire extinguishing systems and fire fighting principles position, The situation for this meeting were prefabricated building fire extinguishing system. Fire alarm system and gas joint protection area to discuss the safe evacuation, The quality of fire extinguishing agent appropriate security in line with national technical standards. So the use of total flooding fire extinguishing system prefabricated. That is, protection zone within the time specified a certain concentration of fire extinguishing gas jet and make it evenly throughout the protection area is full of fire extinguishing system. Safe and efficient protection, the adoption of; Demonstrated through scientific experiments, the best time to fight fire is fire stage, the sooner the alarm of fire, the more easily fire, to the
