新型水系灭火剂自动喷水灭火技术试验研究

摘要

为突破自动喷水灭火系统以会展中心为代表的高大空间场所应用高度的限制以及进一步提升其灭火效能,开展了在净空高度为20 m、新型水系灭火剂应用下的自动喷水灭火系统控灭火性能研究.试验结果表明,自动喷水灭火系统在20 m高净空场所下能及时动作,在按1%混合比添加具有良好渗透性能及热凝胶性能的新型水系灭火剂后,提高了水在燃烧物表面的粘附能力和停留时间.在给定的喷水强度下,仅开放3只喷头即能有效控制火势的增长和蔓延,系统的控火性良好.%In order to break the limitation of the application height of automatic sprinkler systems in the high clearance facilities such as exhibition center, experiment study has been carried out on the fire extinguishment performance of auto sprinkler systems added new type water based extinguishing agent under 20 m ceiling height.Experiment result showed that auto sprinkler system actuat-ed under 20 m high ceiling,1% proportioning ratio of new type wa-ter based extinguishing agent entended the stayment of the water on the combustion surface, and the system controled the fire with only 3 sprinklers activated under preset water density. The system has excellent fire control behavior.
