高压细水雾灭火系统在大型综合交通枢纽工程中的应用与探讨

Application and Research of High-Pressure Water Mist Fire-Extinguishing System in a Large-scale Comprehensive Transportation Hub

结合天津站综合交通枢纽的特点,分析地下大空间公用建筑电器设备火灾的危险性,总结国内外地铁气体灭火系统的现状及存在的问题,研究高压细水雾系统应用的可行性和方式,为大型综合交通枢纽工程中电器设备间的消防工程开发了一种更为节能、环保、经济的系统。

In this thesis, in combination with the characteristics of Tianjin Station comprehensive transportation hub, the fire risk of electrical equipment in a underground large-space public building was analyzed, and the current situation and problems existing in gas fire extinguishing system used in domestic and international metros were summarized. Moreover, the feasibility and the mode about the application of high-pressure water mist system were studied. On this basis, a new fire protection system for electrical equipment room in large-scale comprehensive transportation hub was developed in this thesis, which is more energy-efficient, more environment-friendly, and more economical.
