Embodiment 1

[0044] refer to figure 2 As shown, this embodiment provides a fire smoke component quantitative detection device 100, which is used to simulate the combustion process of the material to be tested in a fire scene, so as to quantitatively detect the smoke component produced by the combustion of the test object. The fire smoke component quantitative detection device 100 includes a combustion chamber 10 , a ventilation system 20 , a weighing system 30 , a smoke detection system 40 and a smoke exhaust system 50 .

[0045] Please refer to the picture figure 2 with image 3 , the combustion chamber 10 includes a combustion zone 101 , a smoke layer zone 102 and a smoke detection zone 103 which pass through in sequence from left to right. That is, the combustion area 101 , the smoke layer area 102 and the smoke detection area 103 are arranged side by side.

[0046] The combustion zone 101 is provided with a hatch 104 that can be opened or sealed. The hatch 104 is used for taking a...

Abstract

The invention provides a fire smoke component quantitative detection device, which relates to the technical field of fire analysis. It includes: a combustion chamber, including a combustion area, a smoke layer area and a smoke detection area that pass through from left to right in sequence, and the combustion area is provided with a hatch that can be opened or sealed. The weighing system installed in the combustion area includes a support for placing the object to be tested and a weighing device connected to the support; a ventilation system connected to the combustion area is used to provide fresh air for the combustion area. The smoke detection system connected with the smoke detection area is used to detect the smoke components; the smoke exhaust system is connected with the outlet of the smoke detection area. The material to be tested is burned in the combustion area, and the ventilation volume is accurately controlled through the ventilation system. The multi-zone setting of the combustion chamber enables the smoke generated by combustion to be effectively separated from the fresh air, and the smoke layer area and the detection area are used to enhance the smoke mixing effect , which is closer to the actual fire scene and accurately reflects the smoke of the object under test.

Description

technical field [0001] The invention relates to the technical field of fire analysis, in particular to a quantitative detection device for fire smoke components. Background technique [0002] In recent years, fire accidents have occurred frequently, involving hotels, shops, dormitories and other places with limited space, causing serious casualties and property losses. In a fire, 70% of casualties are caused by toxic fumes. Therefore, it is of great significance to accurately detect the formation of toxic gases in the combustion process of indoor combustibles, such as wood boards and sofas, for the study of fire safety. For indoor fires, the combustion of combustibles is uncontrolled combustion, and the fire development includes growth phase, ventilation restriction phase and decay phase. Since the air supply in a fire scene is mainly controlled by the thermal buoyancy turbulence formed by the fuel burning flame, the ventilation rate in the fire is constantly changing as th...
