某会议楼七氟丙烷防火及联动报警设计

河南理工大学本科毕业设计1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。关键词：七氟丙烷；预制式灭火系统；火灾联动报警系统；防火分区；安全疏散河南理工大学本科毕业设计2HeptafluoropropaneaconferencebuildingfireandDesignoflinkagealarmAbstract：Therelativeconcentrationofmodernofficeworkers,Highlevelsofeconomicfacilities,hereforerequireahigherleveloffiresafety.thisbuildingishigh-levelmeeting,AccordingtoBuildingcodeforfireprotection,thefloorleveloffiresafetyrequirementsfora,Mostofthefirehydranthasbeeninstalledwiththeregionalwatersprinklersystemsandfireextinguishingsystem,Thearchivesofthefirstfloor,secondfloorcomputerroomandlibraryneedtousegasFire.Ofgasfireextinguishingmaterialcommonlyusedtointroducethefireextinguishingsystemsandfirefightingprinciplesofcomposition,Thesituationforthismeetingwereprefabricatedbuildingfireextinguishingsystem.Firealarmsystemandgasjointprotectionareatodiscussthesafeevacuation,Thequalityoffireextinguishingagentappropriatesecurityinlinewithnationaltechnicalstandards.Sotheuseoftotalfloodingfireextinguishingsystemprefabricated.Thatis,protectionzonewithinthetimespecifiedacertainconcentrationoffireextinguishinggasjetandmakeitevenlythroughouttheprotectionareaisfulloffireextinguishingsystem.Safeandefficientprotection,theadoptionof;Demonstratedthroughscientificexperiments,thebesttimetofightfireisfirestage,thesoonerthealarmoffire,themoreeasilyfire,tothegreatestextentpossibletoavoidfirelosses,firedetectorsandmanualalarmusingacombinationoftheinformationTimelyfeedbacktothefirecontrolcenterinordertomakeasynthesisofitsjudgments,theimplementationoftherelevantcontingencyplans,whichcanbeprovedthatthefirealarmsysteminanimportantpositionlinkage;Protectionareaofgassafetyevacuationtimefor30s,thefireextinguishingagentathightemperatureswillproduceharmfulHF,evacuation河南理工大学本科毕业设计3timemustbelessthantheactualevacuationtime,provethedesignisreasonable,thefinalhasbeencalculated,designedtomeetnationalstandards,moreReasonable.Keywords:Heptafluoropropane;PrefabricatedfireextinguishingsystemFirealarmsystemlinked;FireDistrict;Evacuation河南理工大学本科毕业设计4目录引言...............................................................................................................................6第一章某会议楼七氟丙烷（FM-200）灭火系统设计........................................71.1某会议楼工程概况.....................................................................................71.2七氟丙烷（FM—200）灭火系统..............................................................81.2.1七氟丙烷灭火性能及灭火机理...........................................................81.2.2七氟丙烷灭火系统设计原理...............................................................91.3系统设计........................................................................................................111.3.1灭火方式..............................................................................................111.3.2防火区的划分......................................................................................111.3.3系统组成及要求.................................................................................121.4系统设计计算与选型.................................................................................141.4.1系统计算.............................................................................................141.4.2系统主要组件和设备型号.................................................................17第二章自动报警及联动控制系统设计规定.........................................................192.1火灾自动报警的设计原则...........................................................................192.2自动报警及联动控制系统设计的设计要求...............................................202.2.1自动报警系统设计要求.....................................................................202.2.2联动控制设计要求..............................................................................23第三章联动型火灾报警控制系统...........................................................................233.1联动型控制系统集成....................................................................................233.3.1联动型火灾报警控制系统简介..........................................................233.1.2系统工作原理.....................................................................................243.1.3系统中各组成部分的作用...............................................................253.2火灾自动报警系统.......................................................................................26河南理工大学本科毕业设计53.2.1火灾自动报警系统的组成.................................................................263.2.2火灾探测器的特点与分类..................................................................273.2.3火灾自动报警器的基本形式.............................................................313.3联动控制系统............................
