Pulse type fire extinguishing device with low-density agent and electrical equipment

Abstract

The invention relates to a pulse type fire extinguishing device with a low-density agent and electrical equipment. The pulse type fire extinguishing device with the low-density agent comprises a fire extinguishing container and an aerosol fire extinguishing agent, wherein the aerosol fire extinguishing agent is placed in the fire extinguishing container and is used for spraying fire extinguishing substances to the outside from the fire extinguishing container after ignition, and the density of the aerosol fire extinguishing agent is smaller than 12.9 g / mm<3>. According to the pulse type fire extinguishing device with the low-density agent and the electrical equipment, due to the fact that the density of the agent is smaller than 12.9 g / mm<3>, the aerosol fire extinguishing agent can be in full contact with oxygen, the combustion speed is increased in a geometric multiple mode, the reaction is violent, the capacity of the fire extinguishing substances generated in unit time is large, the spraying speed is high, the generated pulse intensity is high, so that extremely strong impact can be generated on flames, an ignition source is directly cut off, the ignition source is effectively separated from combustible materials, continuous combustion of the flames is successfully blocked, and a good fire extinguishing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a pulse type fire extinguishing device with low-density chemicals and electrical equipment. Background technique [0002] At present, the fire extinguishing methods commonly used in the market mainly include pipe network aerosol fire extinguishing method, fire detection pipe perfluorohexanone fire extinguishing method, pipe network dry powder fire extinguishing method and pipe network water system fire extinguishing method. [0003] Among them, the pipe network aerosol fire extinguishing method is that the powder column burns layer by layer to release the fire extinguishing substance, and the fire detection tube type perfluorohexanone fire extinguishing method uses perfluorohexanone as the fire extinguishing medium, and there is no need to lay fire extinguishing agent delivery pipelines, which can be passed through the sensor The temperature detection fire tube senses the...
