Backdraft experimental device and method for testing backdraft critical conditions and parameters based on backdraft experimental device

Abstract

The invention discloses a backdraft experimental device and a method for testing backdraft critical conditions and parameters based on the backdraft experimental device. The device comprises a box body, a controller, a touch screen display, a remote monitoring terminal, a combustion table, a component analysis unit, a real-time monitoring unit and a temperature detecting unit box; one side of thebox body is provided with a door; the other side of the box body is provided with a transparent board; the combustion table is provided with a combustible material and an ignition assembly; the component analysis unit is communicated with the box body; the real-time monitoring unit is disposed in the box body and is connected with the controller; and the temperature detecting unit is disposed in the box body and is connected with the controller. The device has the advantages of simple structure, reasonable design and easiness in control. A control variable method is used to measure the backdraft critical conditions and parameters of combustible materials, and therefore, optimal disaster relief paths can be provided for firefighters, and the personal safety of the firefighters can be fullyensured.

Description

technical field [0001] The invention relates to a backburning experimental device and a method for testing backburning critical conditions and parameters based on the device. Background technique [0002] Flashback is a phenomenon in which hot smoke re-burns sharply due to a sudden and large amount of fresh air after a fire in a building with limited ventilation enters anoxic combustion or even smoldering. The flashback phenomenon threatens the safety of human beings, especially the safety of firefighters, because of its suddenness and powerful destructiveness. At present, people's critical conditions and restraint methods are not perfect. For example, the patent application "Blowback Experimental Device" with the publication number CN1467036A, although it can be used to study the impact of different opening forms, ventilation methods, and fuel types on the backfire. However, it cannot realize the detection of conditions such as fuel position, fuel shape, ignition source po...

Problems solved by technology

At present, people's critical conditions and suppression means are not perfect. For example, the patent application "Blowback Experimental Device" with the publication number CN1467036A, although it can be used to study the impact of different opening forms, ventilation methods, and fuel types on the backfire. However, it cannot realize the detection of fuel position, fuel shape, ignition source position, temperature, critical components of back-burning gas and other conditions, and, according to its experimental data, it is impossible to determine the best fire fighter The disadvantages of disaster relief routes and ensuring the personal safety of firefighters are still very obvious
