Spherical explosive powder fire extinguisher

Abstract

The invention relates to a spherical explosive powder fire extinguisher, comprising a spherical shell and a dry powder extinguishing agent, wherein the spherical shell is filled with the dry powder extinguishing agent; a satchel charge and an ignition device are arranged at the center of the spherical shell; the ignition device is used for controlling detonation of the satchel charge; the spherical shell is composed of two semispherical shells; the ignition device preferably is a remote control ignition device which is arranged at the center position of the spherical shell, or a temperature control blasting fuse which is arranged out of the spherical shell and is connected with the satchel charge through a lead; the shell and the internal dry powder extinguishing agent are simultaneously exploded by the explosive force which is generated after the satchel charge in the fire extinguisher explodes; the dry powder extinguishing agent is evenly sprayed on a comburant in a fire, so as to put out the fire; an impact wave generated in explosion also plays a fire-extinguishing role; and the fire-extinguishing effect is significant.

Description

technical field [0001] The invention relates to a fire extinguisher, in particular to a spherical explosive dry powder fire extinguisher. Background technique [0002] At present, commonly used fire extinguishers include foam fire extinguishers, water mist fire extinguishers, pressure handle type dry powder fire extinguishers, etc., and can also be used to directly spray the fire source with a water pipe to extinguish the fire. The above fire extinguishing process needs to be operated in the fire field with fire extinguishing tools when a fire occurs, and the fire extinguishing speed is slow. The fire extinguishing effect is not obvious, and people and fire extinguishing tools must be close to the fire source simultaneously during operation, which brings hidden dangers to the life safety of fire extinguishers. [0003] And the fire extinguishing effect of the fire extinguishing agent added in the existing fire extinguisher is not ideal, and some fire extinguishing agents als...

AI Technical Summary

Problems solved by technology

[0002] At present, commonly used fire extinguishers include foam fire extinguishers, water mist fire extinguishers, pressure handle dry powder fire extinguishers, etc., and can also be used to directly spray the fire source with a water pipe to extinguish the fire. The above fire extinguishing process needs to be operated in the fire field with fire extinguishing tools when a fire occurs, and the fire extinguishing speed is slow. The fire extinguishing effect is not obvious, and people and fire extinguishing tools must be close to the fire source at the same time during operation, which brings hidden dangers to the life safety of fire extinguishers

[0003] Moreover, the fire extinguishing effect of the fire extinguishing agent added in the existing fire extinguisher is not ideal, and some fire extinguishing agents also play a combustion-supporting effect after failure, which further affects the fire extinguishing effect
