Problems solved by technology

Most of the existing fire extinguishing agents use ammonium phosphate as the oxidant, which has high raw material costs and slow oxidation reaction speed. The fire extinguishing efficiency is low when dealing with fires in small and closed spaces. The fire extinguishing method of spraying can easily cause local flames to extinguish slowly or cannot be extinguished
More importantly, the fire extinguishers that can be used in relatively small and closed areas such as public equipment at present, in order to facilitate the spraying of fire extinguishing agents after the reaction, generally adopt a semi-open installation structure. In larger cases, it is easy to cause chemical spillage, and it has high requirements for the installation site, so it cannot be fastened to the vertical working surface, or even installed upside down
[0003]Based on the above reasons, the fire extinguishing system currently dealing with the narrow and even closed spaces such as the engine room in the public transport equipment, for the vehicles in use, the work is unstable, High use cost and low fire extinguishing efficiency

Abstract

The invention relates to an extinguishing agent and an engine compartment extinguishing apparatus using the extinguishing agent. The extinguishing agent is mainly composed of potassium nitrate, phenolic resin, magnesium powder and inflammable powdered carbon. The extinguishing apparatus comprises an extinguishing module used for storing the extinguishing agent and enforcing fire extinguishing, a temperature sensing module used for sensing the temperature, and a control module connected with the above modules respectively, and the extinguishing module is provided with a gas bottle used for storing the extinguishing agent, a nozzle connected with a starting valve, a extinguishing communication unit connected with the starting valve and the control module respectively, and a power supply unit used for providing electric energy for the starting valve and the extinguishing communication unit. The above extinguishing system controls the control module to realize concentrated control and omit a pipeline system, is suitable for the small and closed space of buses, adopts the fast-reaction extinguishing agent and a directive nozzle to improve the extinguishing efficiency and realize easy installation and maintenance, and is especially suitable for the fire prevention and extinguishing of a closed space. The extinguishing agent, the engine compartment extinguishing apparatus and the extinguishing method also have the above advantages.

Description

technical field [0001] The invention relates to a fire extinguishing agent, in particular to an aerosol fire extinguishing agent, fire extinguishing equipment using the fire extinguishing agent and a fire extinguishing method thereof . Background technique [0002] The space of engine, fuel tank, luggage and other components in transportation equipment is relatively narrow and closed. Once fuel leaks during work, it is easy to cause fire and the consequences are quite serious. Most of the existing fire extinguishing agents use ammonium phosphate as the oxidant, which has high raw material costs and slow oxidation reaction speed. The fire extinguishing efficiency is low when dealing with fires in small and closed spaces. The fire extinguishing method of spraying can easily cause local flames to extinguish slowly or cannot be extinguished. More importantly, the fire extinguishers that can be used in relatively small and closed areas such as public equipment at present, in ...
