文档介绍：摘要图书馆储藏大量图书和文字资料,不仅具有经济价值,书籍本身更具有重大文化价值。图书馆本身作为大型公共场所,人员密度大,人口流动大,在火灾方面藏有巨大安全隐患。本次设计是根据国家相关法律法规,对哈尔滨图书馆进行七***丙烷灭火系统设计和火灾自动报警系统设计。在七***丙烷灭火系统设计中,将哈尔滨图书馆合理划分为 22个防护区, 对七***丙烷灭火系统的设置进行了分析与计算。最终确定共需喷头种类 JP—16、 JP—18、 JP—20、 JP—22 共 4种,喷头数量总计 88个。在火灾自动报警系统设计中,将该图书馆划分为4个报警区域和 50个探测区域并进行合理设计。共选用了 110 个感烟探测器、 311 个感温探测器、 58个手动报警按钮和 54个声光报警器。在设计的结尾部分,对哈尔滨图书馆本身的设计进行了安全疏散验证且验证合格,最大限度保证建筑内人员及财产的安全。关键词: 七***丙烷;火灾自动报警;安全疏散 II ABSTRACT There is an enormous amount ofbooks and documents in the library. Not only has it economic value, but also has it significant cultural value. Tremendous as the library is, full of population, there must have some hidden safety. The aim of this graduation is to design the FM-200 system and the automatic fire alarm system using a legal way in the Harbin library. In the FM-200 system, it has been divided into 22 protection parts. According to the accurate analysis and calculation, it has finally decided to choose JP-16, JP-18, JP-20, and JP-22 around 88 nozzles. In the automatic fire alarm system, it has been fallen into 4 firealarm areas and 50exploration areas, including 110 smoke detectors, 311 temperature detectors, 58 manual warning buttons, and 54 audible and visual alarms In the end, the design has maximized to ensure the safety of evacuation and property.
