<p><P>PROBLEM TO BE SOLVED: To enable high fire extinguishing and smoke consuming effect using Coulomb force by securing sufficient charging amount even when a spraying amount is increased, and to widely and uniformly spray a fire extinguishing agent having a large charging amount. <P>SOLUTION: In the event of a fire, a water-based fire extinguishing agent is supplied to a charging spray head 10 installed in protection sections through piping by applying pressure; the fire extinguishing agent injected from the charging spray head 10 is deflected in an arbitrary direction to form a thin film flow 56, and then fragmented and separated into particle group flows 58 for spraying; and an external electric field is applied to the vicinity of the fragmented and separated part P of the thin film flow 58 and charged. The charging spray head 10 includes: a nozzle part 40 that injects a fire extinguishing agent to the outside space; a fire extinguishing agent side electrode part 46 that is arranged inside the nozzle part 40 to come in contact with the fire extinguishing agent; a deflector 42 that, after deflecting the fire extinguishing agent discharged from the nozzle part 40 in an arbitrary direction to form the thin film flow 56, fragments and separates it into the particle group flow 58 for spraying; and an induction electrode part 48 that is arranged near the fragmented and separated part P of the thin film flow 56. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
