高压单相流细水雾灭火系统研制及实验研究

Development of high-pressure single-fluid water mist fire protection system

细水雾灭火以其高效、环保的特点已经成为最具有发展潜力的哈龙替代技术之一。浙江大学流体传动及控制国家重点实验室成功研制了高压单相流细水雾灭火系统 ,采用激光相位多普勒粒子测速仪 (Phase Doppler ParticleAnemometer,PDPA)测量了喷雾参数 ,并参照国际标准进行了细水雾灭火实验。实验结果显示 ,系统喷出的雾滴属于一级细水雾 ,雾云的电绝缘性和驻留性良好 。

Water mist has become one of the most potential replacements of Halon with high efficiency and friendly environment compatibility. A high-pressure single-fluid water mist fire protection system is successfully developed in the State Key Laboratory of Fluid Power Transmission and Control. The spray parameters are measured with the Phase Doppler Particle Anemometer (PDPA) system. Some fire extinguishing tests are carried out according to the related standards. The results show that the mist clouds sprayed from the water mist fire protection system belong to the finest group, which can put out a fire quickly and effectively with good electrical insulation and capability of long hanging in space.
