Problems solved by technology

[0003] The explosion hazard of flammable liquids has always been the focus of attention. In recent decades, explosion accidents caused by flammable liquids have caused a large number of casualties and serious property losses.
[0013] At present, there are only some models for predicting fireballs of liquid explosions in China, and there is no test method for determining the fire and explosion hazards of flammable liquids under unconstrained conditions. Therefore, the understanding of the explosion hazards of flammable liquids lacks an experimental basis

Abstract

The invention discloses a method for evaluation of inflammable liquid explosion risk under unrestricted condition in an outfield. The method comprises the following steps of 1, selecting a test place and meteorological conditions, 2, pouring an inflammable liquid sample into a simulation container, 3, determining a position of the simulation container and a position of a determination system and arranging the simulation container and the determination system according to the positions, and 4, arranging an ignition device and carrying out ignition and 5, evaluating risk. The method for evaluation of inflammable liquid explosion risk under unrestricted condition in an outfield can realize explosion process determination under unrestricted condition in the outfield, realize simulation of explosion process conditions approximate to real explosion process conditions and accurately evaluate inflammable liquid explosion risk under unrestricted condition in the outfield.

Description

technical field [0001] The invention relates to a method for judging explosion hazards, in particular to a method for judging the explosion hazards of combustible liquids under unconstrained conditions in an external field. Background technique [0002] The explosion test of flammable liquids under unconstrained conditions refers to the explosion test of flammable liquids placed in an open space, and the dangers include thermal damage and shock wave damage caused by the liquid igniting and exploding. [0003] The explosion hazard of flammable liquids has always been the focus of people's attention. In recent decades, explosion accidents caused by flammable liquids have caused a large number of casualties and serious property losses. The safety problems of flammable liquids are prominent, especially in special environments such as fire fighting, which put forward higher requirements for the safety of flammable liquids. Therefore, all countries in the world attach great impor...
