【摘要】：自2002年多个省市颁布当地标准《细水雾灭火系统设计施工及验收规范》以来,细水雾灭火系统并未取得实质发展,在实体建筑物的设计和使用方面进展缓慢。随着近几年快递业发展及高大空间物流仓库的发展,大数据应用以及IDC机房建设的兴起,仓储及数据中心(机房)的消防灭火问题俞显紧迫!传统上这些场所的灭火设备首选气体灭火系统,但对于数据中心(机房)来说,因气体灭火系统在大空间的设置限制,使得高压细水雾灭火系统的设计逐步兴起。高压细水雾成套设备由国外迅速进入国内市场,并且在烟草仓库、档案馆以及IT机房取得了大量投入使用的业绩。高效的火势控制能力是高压细水雾灭火系统的最大优点,也是高压细水雾灭火系统能够代替气体灭火系统的原因。无毒环保是相对气体灭火系统来说的优势,一次灭火用水量是喷淋系统的5%,是相对于传统喷淋系统的优势。基于这种前景,本文对高压细水雾灭火系统从灭火原理、实际工程方案的制定、设计到最终的工程应用案例,均有所关注。并希望在此基础之上,建立“高压细水雾灭火试验台”作为高压细水雾灭火系统控制的方案验证,为实际工程的使用进行事前研判。本论文从火灾发生的机理和高压细水雾灭火系统的机理分析着手,以便使普通读者了解基本的火灾发生和控制的基本过程。随后,从信息机房及其辅助用房使用功能角度,证明高压细水雾灭火系统,相对于普通的喷淋系统和气体灭火系统来说,是目前最优的控制火灾的设计方案。作为实证案例,根据农行信息中心的工程设计要求,以国外某知名的高压细水雾系统进行了方案设计。根据火灾自动报警及联动控制系统的要求,设计了相应的控制方案,并根据对湿度的要求,增加了通风控制方案。把建筑空间的面积、高度、使用功能、高压细水雾系统参数以及温、湿参数作为常量,以火灾危险源作为变量,作为仿真系统的输入,输出对高压细水雾喷头的平面布置和角度布置。以温、湿度参数为变量作为辅助控制系统的输入条件,监视火灾进程,控制高压细水雾设备和送排风设备启停,最终达到研究目的。实证研究的初衷,正是希望通过实际工程的使用和实验平台的结合,以实验平台验证设计方案,以实际工程使用效果完善实验平台,并希望之后的研究能够持续进行,最终建立高压细水雾灭火系统控制方案的仿真系统,助力性能化设计。
[Abstract]:Since the local standard "Design, Construction and acceptance Code for Water Mist Fire extinguishing system" has been promulgated in many provinces and cities in 2002, the water mist fire extinguishing system has not made substantial development, and has made slow progress in the design and use of physical buildings. With the development of express delivery industry and the development of large space logistics warehouse in recent years, the application of big data and the rise of IDC engine room construction, the fire fighting problem of storage and data center (engine room) is urgent. Traditionally, the gas extinguishing system is the first choice for the fire extinguishing equipment in these places, but for the data center (engine room), the design of the high pressure water mist fire extinguishing system is rising gradually because of the limitation of the gas extinguishing system in the large space. High pressure water mist complete sets of equipment from abroad to enter the domestic market rapidly, and in the tobacco warehouse, archives and IT computer room has achieved a large number of achievements. High efficiency fire control capability is the biggest advantage of high pressure water mist fire extinguishing system, and it is also the reason why high pressure water mist fire extinguishing system can replace gas extinguishing system. Non-toxic environmental protection is the advantage of the gas fire extinguishing system. The water consumption of the primary fire extinguishing system is 5% of the sprinkler system, which is the advantage compared with the traditional sprinkler system. Based on this prospect, this paper pays close attention to the fire extinguishing principle of high pressure water mist fire extinguishing system, the formulation of practical project scheme, the design of the fire extinguishing system and the final engineering application case. On the basis of this, it is hoped that the "high pressure water mist fire extinguishing test rig" will be established as the scheme verification for the control of the high pressure water mist fire extinguishing system, and the practical application of the fire extinguishing system will be studied in advance. In this paper, the mechanism of fire occurrence and the mechanism of high pressure water mist fire extinguishing system are analyzed in order to make ordinary readers understand the basic process of fire occurrence and control. Then, from the point of view of the function of the information machine room and its auxiliary room, it is proved that the high pressure water mist fire extinguishing system, compared with the common sprinkler system and the gas extinguishing system, is the best design scheme for fire control at present. As an empirical case, according to the engineering design requirements of Agricultural Bank Information Center, the project is designed with a famous high pressure water mist system abroad. According to the requirement of automatic fire alarm and linkage control system, the corresponding control scheme is designed, and the ventilation control scheme is added according to the requirement of humidity. Taking the building space area, height, use function, parameters of high pressure water mist system, temperature and humidity as constant, fire hazard as variable, as the input of simulation system, The output plane arrangement and angle arrangement of the high pressure water mist nozzle. The parameters of temperature and humidity are taken as the input conditions of the auxiliary control system to monitor the fire process and to control the start and stop of the high pressure water mist equipment and the air supply and exhaust equipment. Finally the purpose of the research is achieved. The original intention of the empirical research is to verify the design plan through the combination of the actual engineering and the experimental platform, and to perfect the experimental platform with the practical engineering effect, and hope that the later research can be carried on continuously. Finally, the simulation system of high-pressure water mist fire-extinguishing system is established to assist the performance design.
