Description

Device for simulating and stabilizing combustion environment of combustion improver

Technical Field

The utility model relates to a simulation combustion environment technical field specifically is a combustion improver combustion environment device is stabilized in simulation.

Background

In the prior art, the pilot fire is a commonly used crime criminal committee and is also one of the causes of fire. The longitudinal fire cases are mostly hidden in common fire, and the fire scene property can be determined only by surveying the fire scene and investigating the fire cause. However, the field of the longitudinal fire case is complex, the longitudinal fire case is not only damaged by fire, but also damaged by water brewing during fire extinguishing and personnel in the fire scene, and the extracted sample is greatly different from a pure product. Moreover, most combustion improvers in a fire scene are volatile, and particularly, light mineral oil is little remained in the fire scene, so that difficulty is brought to the inspection and identification of the combustion improvers in combustible liquid residues in the fire scene. For the identification of fire scene material evidence, the main method adopted at home and abroad at present is to detect whether flammable liquid with light unburnt or overfire degree exists in the fire scene residues. And on the basis of the analysis, various analysis means are adopted for analysis. However, the use of the identification method is premised on timely fire suppression, no serious fire field combustion, and the extracted sample is required to be very pure and not to be polluted, otherwise, the residual flammable liquid component in the fire field is not easy to detect. However, fire sites are often damaged by oxidation, combustion, water bubbles and fire fighting personnel, and the extracted samples are often contaminated. And most combustion improvers in a fire scene are volatile, and particularly light mineral oil is difficult to find in the high-temperature environment of the fire scene. The conventional method for judging whether the combustion improver exists in the fire scene or not by detecting the residues of combustible liquid in the fire scene often encounters a plurality of difficulties in the process of detection and identification. The inventor research team finds that the metal material which is widely applied in the building field is generally not flammable, but in a fire environment, the metal material interacts with the surrounding environment combustion atmosphere to generate chemical reaction. Therefore, different metal materials can be oxidized by simulating different combustion environments of the combustion improver, so as to determine the relationship between the oxidation atmosphere of different combustion improvers and the surface oxidation forms after the metal is oxidized.

The existing device for simulating the combustion environment of the combustion improver has the defects that only one combustion improver and one combustion material can be tested at one time, the combustion temperature is unstable, and the combusted gas is not treated and is directly discharged.
