Fine Water Mist Fire Extinguishing Device
Descripción
1.The high pressure water mist system device uses water as the fire extinguishing medium, and uses a special atomizing nozzle to decompose the water flow into small water droplets to extinguish the fire under a specific pressure (usually the minimum pressure of the nozzle is 10MPa). With the characteristics of economy and wide application, it has become an important technology to replace the halon fire extinguishing system, and has a wide application prospect.
2.Fine water mist: sprayed at the minimum working pressure of the nozzle, measured on a plane 1m down from the axis of the nozzle, the water mist with the droplet size Dv0.99 less than 400μm, and Dv0.50 less than 200μm.
Composition and working principle
The water mist fire extinguishing device consists of a high-pressure water mist special water storage tank, a water mist fire extinguishing device pump unit (including high-pressure main pump, high-pressure backup pump, voltage stabilizer pump, pump unit control cabinet, water inlet solenoid valve, water inlet filter It is composed of water supply system, water supply pipe network, partition control valve box group of water mist fire extinguishing device, water mist sprinkler, high pressure water mist pipeline and fire detection and alarm system. It works as follows:
