AI Technical Summary

Technical Problem

Existing dry powder explosion suppression materials are insufficient for suppressing explosions in hydrogen/hydrogen storage metal powder composite systems, and cannot effectively cope with their high sensitivity and rapid explosion process.

Method used

An inert gas/liquid-solid composite modified dry water explosion suppression material is used. The inert gas drives the liquid-solid composite modified dry water material to be uniformly dispersed in a confined space. Combined with salt additives and surfactants, a stable modified mixture is formed. The explosion suppression effect is improved by the synergistic effect of physical endothermic and chemical blocking.

Benefits of technology

It significantly reduces the peak explosion pressure and prolongs the time to peak pressure arrival, achieving a synergistic effect of physical and chemical explosion suppression, improving explosion suppression efficiency, material stability, and ease of use.
