Title:
FOG FIRE EXTINGUISHING METHOD AND DEVICE
Document Type and Number:
Japanese Patent JP3885145
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make a fire extinguish liquid reach a fire source in the form of fog by enclosing a fire extinguishing liquid and pressurized gas, and alternately spraying both from a fog nozzle.
SOLUTION: Pressurized gas 7 and a fire extinguishing liquid 8 are enclosed in a pressure container 2, and a selector float 3 is provided as a fluid selector means for alternately supplying the fire extinguishing liquid 8 and the pressurized gas 7 to a fog nozzle 5. When a fire occurs, one opening the valve of a nozzle hose 6, the fire extinguishing liquid 8 is sprayed through the nozzle hose 6 from the fog nozzle 5 by pressure of the pressurized gas 7. By such spraying, the liquid level L is disturbed so that the state where only the fire extinguishing liquid 8 or the pressurized gas 7 is sucked from a fluid suction port is repeated in a short cycle. Accordingly, short cycle injection of pressurized gas 7 only occurs, so that injection is repeated in irregular cycle in the order of the fire extinguishing liquid 8 → the pressurized gas 7 → the fire extinguishing liquid 8. Thus, the fog of the fire extinguishing liquid 8 can be forced to reach a fire source by the pressurized gas 7.
