6 FAQs about [Energy storage airbag explosion]

Does airbag suppression effect on methane/air explosion shock wave and flame?

This work aims to verify the suppression effect of airbag on the methane/air explosion shock wave and flame through a flexible explosion suppression system and analyze the suppression mechanism of airbag shrinkage and deformation energy absorption on shock wave. 2. Experimental System and Method 2.1. Flexible-Airbag Gas-Explosion Suppression System

Why do explosion suppression airbags fire naturally?

In the process of energy absorption by the airbag, the flame is extinguished naturally, because the methane in the pipeline cannot be replenished, which leads to the interruption of the explosion. Based on the two-dimensional model, the stress and deformation theory of the explosion suppression airbag is analyzed.

How long does an explosion suppression airbag take to deploy?

The actual volume of the airbag deployed in the pipeline is 3.81 L. The experiment verifies that the deployment time of the explosion suppression airbag can be controlled within 20 ms, and the time required by the explosion suppression agent system and the execution system is 22.8 ms.

What is a flexible airbag gas-explosion suppression system?

A flexible-airbag gas-explosion suppression system is composed of a detection system, a gas generator, a powder storage tank, and a closed diaphragm. The gas generator is the key component of the explosion suppressor agent system.

What is the stress and deformation theory of explosion suppression airbag?

Based on the two-dimensional model, the stress and deformation theory of the explosion suppression airbag is analyzed. The law of deformation energy absorption and the relationship between internal pressure and external pressure during the process of the airbag from the initial state to the ultimate state are obtained.

What is the maximum overpressure in airbag explosion suppression experiment?

The difference between the theoretical value and the maximum overpressure at the pressure measuring point P3 (0.358–0.37 MPa) in the airbag explosion suppression experiment is 0.0148–0.0268 MPa, and the maximum error is 7.8%.
