Fine water mist multiple orientation discharge fire extinguisher

摘要

The present invention is directed to a suppression system in which a carrier gas and suppression liquid are contained in a common containment vessel and separated by a separation member. The separation is one or more of movable, deformable, or shape changing in response to pressure exerted by the stored gas.

主权项

1. A method for suppressing an exothermic reaction, comprising:
(a) directing an outlet of a suppression device towards the exothermic reaction; (b) opening a valve to permit a suppression liquid and carrier gas in a containment vessel to flow from a containment vessel, the liquid and carrier gas being located in the containment vessel and separated from one another by at least one of a movable and deformable separation member; (c) after the liquid and carrier gas flow from the containment vessel, mixing the liquid and carrier gas to form a suppression fluid, the suppression fluid being in the form of droplets of the liquid dispersed in the carrier gas, wherein the mixing step comprises the substeps:
(C1) passing the liquid through a central passageway of an aspirating venturi;(C2) passing the gas through at least one aspirating tube of the aspirating venturi to form the suppression fluid;(C3) passing the suppression fluid through an aperture to accelerate the suppression fluid to a supersonic velocity;(C4) expanding the gas to form droplets of the liquid entrained in the gas; and(C5) decelerating the droplets of liquid to below a sonic velocity to form an atomized suppression fluid comprising atomized droplets dispersed in the gas; and (d) discharging the atomized suppression fluid in a direction of the exothermic reaction.
