Embodiment Construction

[0016] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0017] Such as Figure 1-2 As shown, a kind of chemical fire fuel identification method based on combustion product of the present invention, its steps are as follows:

[0018] a. Select a chemical combustible sample with high purity, put the sample into the flue gas generating device for combustion, and then start the first fan in the flue gas generating device to input the flue gas generated by combustion into the mixing device;

[0019] b. Turn off the first fan, start the second fan in the mixing device to input the mixed flue gas in the mixing device into several light chambers through capillary tubes, and collect the radiation intensity changes caused by the direct light and scattered light in the light chamber affected by the flue gas data;

[0020] c. Input the data into the database established by the computer, randomly sel...

Abstract

The invention relates to the technical field of chemical fire prevention and control, in particular to a combustion product based chemical fire fuel identification method. The method includes the steps of: a. selecting a high purity chemical combustible sample, putting the sample into a flue gas generation device for combustion, and inputting the flue gas produced by combustion into a mixing device; b. inputting the uniformly mixed flue gas in the mixing device into several light chambers through capillary tubes, and collecting the radiation intensity variation data generated by the influenceof flue gas on direct light and scattered light in the light chambers; and c. inputting the data into a database established a computer, randomly selecting part of the data in the database as the training set, performing training by Randomforest algorithm, and then testing the training set with the rest data so as to determine the effectiveness. The method identifies the influence of flue gas generated by different combustion products on medium-long wave light rays to collect sample data and establish the big database, also employs Randomforest machine algorithm learning to realize rapid analysis and response of fire scene comburent, and can reduce the risk and rescue difficulty of chemical fires.

Description

technical field [0001] The invention relates to the technical field of chemical fire prevention and control, in particular to a chemical fire fuel identification method based on combustion products. Background technique [0002] Due to the complexity of placing items in chemical sites, it is difficult to quickly identify the source of fire and the type of fuel in the event of a fire. For example, in the Tianjin Port incident, due to the lack of understanding of the types of explosives, firefighters adopted incorrect methods of extinguishing the fire, resulting in greater casualties and property losses. Therefore, the rapid determination of the fire category, especially the rapid determination of the fuel type is very important for controlling the fire and reducing losses. During the fire process, a large amount of smoke will be produced due to insufficient combustion of fuel, and a large number of studies have shown that the smoke produced by different types of fuel is diff...
