Fire extinguishing device

Abstract

The invention relates to a fire extinguishing device. The fire extinguishing device comprises a fire extinguishing container, a spraying assembly and a liquid cooling agent; a containing cavity is filled with aerosol fire extinguishing agent and liquid cooling agent, and the aerosol fire extinguishing agent makes direct contact with the liquid cooling agent; and the liquid cooling agent and the aerosol fire extinguishing agent do not generate chemical reaction. According to the fire extinguishing device, after the aerosol fire extinguishing agent is ignited, the aerosol fire extinguishing agent generates high-temperature fire extinguishing substance, and the high-temperature fire extinguishing substance have a certain initial spraying speed and are sprayed to the nozzle along the sprayingpath; in the spraying process to the nozzle, the liquid cooling agent is in direct contact with the aerosol fire extinguishing agent without passing through an air guide channel to absorb heat of thefire extinguishing substance in time, and the corresponding high-temperature fire extinguishing substance releases heat for cooling so as to reduce the temperature of the fire extinguishing substancesprayed out of the nozzle; and the resistance of the liquid cooling agent to the fire extinguishing substance is small, and the fire extinguishing effect is improved while the passing speed of the fire extinguishing substance is not affected; and the liquid cooling agent can be sprayed from the nozzle together with the fire extinguishing substance to extinguish fire.

Description

technical field [0001] The invention relates to the technical field of fire fighting, in particular to a fire extinguishing device. Background technique [0002] Aerosol fire extinguishing agent is a newly developed type of fire extinguishing agent in the field of fire extinguishing. It burns the fuel in the fire extinguishing agent to form a fire extinguishing substance, so as to achieve the purpose of fire extinguishing. [0003] Usually, the temperature of the aerosol fire extinguishing agent is very high after it is sprayed. In the design of the traditional fire extinguishing device, a large amount of space needs to be provided for the air guide channel and the placement of heat-absorbing and cooling substances. During the injection process, the passing speed of the fire extinguishing material is limited, thereby reducing the fire extinguishing efficiency of the aerosol fire extinguishing agent. Contents of the invention [0004] Based on this, it is necessary to solv...

Problems solved by technology

[0004] Based on this, it is necessary to solve the problem that the speed of the fire extinguishing material is limited when the aerosol fire extinguishing agent is ignited to form a fire extinguishing substance sprayed to the nozzle of the traditional fire extinguishing device, thereby reducing the fire extinguishing efficiency of the aerosol fire extinguishing agent. A fire extinguishing device with high fire extinguishing efficiency
