A pressure-suppressing pulse type fire extinguishing method and its fire extinguishing device

Abstract

The invention discloses a pressure-holding pulse type fire-extinguishing method and a fire-extinguishing device. The method comprises the following steps: step 1): placing a fire extinguishing agent in a closed container; step 2): igniting the fire extinguishing agent when a fire occurs; step 3) : The fire-extinguishing substance produced after the fire extinguishing agent is ignited fills the entire airtight container, and the pressure in the airtight container gradually increases; Step 4): The discharge end of the airtight container is opened because the pressure reaches the critical value, and the fire-extinguishing substance is ejected to carry out the fire-extinguishing process; The present invention also provides a corresponding fire extinguishing device; the present invention greatly speeds up the spraying speed of the fire extinguishing material and improves the fire extinguishing efficiency.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a pressure-holding pulse type fire extinguishing method and a fire extinguishing device thereof. 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. Among the above four fire extinguishing methods, The pipe network aerosol fire extinguishing method is that the powder column burns layer by layer to release the aerosol generating agent; the fire detection tube type perfluorohexanone fire extinguishing method uses perfluorohexanone as the fire extinguishing medium, no need to lay fire extinguishing agent delivery pipelines, and can pass through the temperature sensing The fire detection tube sens...

[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. Among the above four fire extinguishing methods, The pipe network aerosol fire extinguishing method is that the powder column burns layer by layer to release the aerosol generating agent; the fire detection tube type perfluorohexanone fire extinguishing method uses perfluorohexanone as the fire extinguishing medium, no need to lay fire extinguishing agent delivery pipelines, and can pass through the temperature sensing The fire detection tube senses the temperature and releases the fire extinguishing agent after starting; the pipe network dry powder fire extinguishing method and the pipe network water system fire extinguishing method are based on the dry powder fire extinguishing method and the water fire extinguishing method, adding the pipe network system to reduce spraying as much as possible However, the above-mentioned fire extinguishing methods all have the same problem. Because they are all affected by the burning area, although the spraying is stable, the spraying speed of the fire extinguishing material is generally slow, and the fire extinguishing efficiency lower
