Fire protection apparatus, systems and methods for addressing a fire with a mist

摘要

Fire protection apparatus, systems, and methods for addressing a fire with a mist are provided. More particularly, the invention provides systems and their method of design which provide a water mist to address and preferably suppress a fire. The invention further provides systems and methods for total flooding volume protection of a space to address a fire, preferably control, suppress, and more preferably extinguish a fire. The invention further provides atomizing devices for use in such systems and methods.

主权项

1. An atomizer for fire protection using a first fluid and a second fluid, the atomizer comprising:
a base, a cover coupled to the base and an internal fluid defining assembly disposed along a longitudinal axis between the base and the cover, the base at a proximal end of the atomizer including a first inlet for receipt of the first fluid and a second inlet for receipt of the second fluid, and the cover defining an outlet at a distal end of the atomizer for discharging the first and second fluid, the fluid defining assembly keeping the first and second fluids isolated from one another from the proximal to the distal end of the atomizer, the assembly including an outer funnel having an inner surface and an outer surface, the outer surface of the outer funnel defining a first fluid flow passageway in communication with the first inlet, the first fluid passage having a divergent-convergent internal geometry and the outer surface defining a continuous curved profile along the longitudinal axis that converges to a first fluid outlet, the first fluid passage the inner surface of the outer funnel defining a second passageway in communication with the second inlet, the assembly including an inner plug member disposed within the passageway and having an outer surface spaced from the inner surface of the outer funnel to define at least a portion of a second fluid flow passageway therebetween extending axially to the outlet, the second fluid flow passageway diverging in the proximal to distal direction to define a discharge orifice for the second fluid in communication with the outlet.
