FIREFIGHTING DEVICE, CHARGED DISPERSAL HEAD, AND CHARGED DISPERSAL METHOD

摘要

A firefighting device comprises: a fire extinguishing agent supply apparatus which supplies a water-based fire extinguishing agent via a pipe; a charged dispersal head which is installed in a protection area, and which charges and disperses discharge particles of the fire extinguishing agent which is pressurized and supplied by the fire extinguishing agent supply apparatus; and a voltage application unit which applies a charge voltage to the charged dispersal head. The charged dispersal head further comprises: a nozzle which discharges the fire extinguishing agent in an external space; a fire extinguishing agent-side electrode unit which is positioned within the nozzle and makes contact with the fire extinguishing agent; a deflected dispersal member which deflects the fire extinguishing agent which comes from the nozzle in an arbitrary direction in a semi-circular shape or a fan shape and forms a thin film flow, and thereafter separates and divides the thin film flow into a particle group flow and disperses same; and an inductive electrode unit which is positioned near a thin film flow separation and division unit.
