Embodiment Construction

[0025]In May 2012, under normal outdoor conditions, according to the number of nozzles, the number of nozzles, the installation height (the height from the top of the wood pile to the nozzle), and the filling pressure, the fire extinguishing test at the standard wooden pile level was carried out 15 times, and the test conditions all met GB4351 .1—2005 and GA602—2006 Class A fire test and local application fire extinguishing test standards, that is, the wind speed is not greater than 3m / s, there is no bad weather such as rain, snow or hail, and the ambient temperature is 40°C-55°C , relative humidity 45%-75%, atmospheric pressure 86KPa-106KPa. A suspended hexafluoropropane fire extinguishing device (Hangzhou Fire Fighting Equipment Co., Ltd., model XQLW8 / 6) is used. The dosage of hexafluoropropane is 6kg. A standard atomizing nozzle is used. The nozzle is circular with a diameter of 21mm, and the nozzle is equilateral 3 There are 3 rotating cores evenly distributed in the angul...

Abstract

The invention provides a method for standard wood crib-grade local fire extinguishing through controlling the particle size of a chexafluoropropane fogdrop. It is determined that the particle size of the hexafluoropropane fogdrop is a key condition for fire extinguishing of a hexafluoropropane local fire extinguishing system. The method provided by the invention has the advantages of a high fire extinguishing success rate, a good fire extinguishing effect, a wide application scope and wide application prospects, fills gaps in application of hexafluoropropane in fire extinguishing and research on fire extinguishing of hexafluoropropane at home and abroad and lays a foundation for large scale popularization and application of hexafluoropropane in local fire extinguishing.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to a method for locally extinguishing fires by controlling the particle size of hexafluoropropane droplets to reach the standard wooden crib level. Background technique [0002] At present, except for the carbon dioxide system, other known gas fire extinguishing systems can only be applied in the way of total flooding, and the research work on finding a gas system that can be used as a local application like the carbon dioxide fire extinguishing system has not yet been systematically carried out. [0003] Industrial developed countries have an earlier history of applying gas fire extinguishing systems. Carbon dioxide fire extinguishing systems began to be used in the world in the 1920s, and halon fire extinguishing systems began to be used in the 1960s. The fire extinguishing agents used in early gas fire extinguishing systems in my country were mainly carbon tet...
