Abstract

A fire suppression system for a fire zone including a first tank containing a first liquid component of a two-part foam and a second tank containing a second liquid component of the foam. The system includes at least one liquid component release device configured to be selectively capable of releasing the first and second components from their respective containers upon receipt of a signal from a fire detector upon detection of a fire. The two-part foam components are propelled through the system by a pressurized propellant that, upon release of the release device, causes the exit of the foam components from their respective tanks, through a mixing conduit to at least one nozzle. The nozzle is configured to spray the liquid component foam mixture into the fire zone wherein the foam cures into a substantially semi-rigid, closed cell foam that is substantially impermeable and may have charring and/or intumescence properties.

Dependent claims

A fire suppression system for a fire zone, said fire suppression system comprising:

a case including a bottom and at least one sidewall;
a first component container mounted within said case, said first component container containing a first liquid foam component of a two-part foam;
a second component container mounted within said case, said second container containing a second liquid foam component of said two-part foam;
at least one component release device mounted within said case, said at least one component release device in fluid communication with said first component container and said second component container, said at least one component release device being configured to be selectively capable of releasing said first and second foam components from said first and second component containers;
a fire detector operably connected to said case, said fire detector in electric communication with said at least one component release device, wherein said fire detector electronically signals for the release of said first and said second liquid foam components upon detection of smoke and/or heat;
a propellant in fluid communication with said first and said second foam component wherein the activation of said at least one component release device results in at least one of (i) a unrestrained positive pressure applied upon said first foam component and said second foam component by said propellant thereby causing the exit of said first foam component from said first component container and the exit of said second foam component from said second component container, and (ii) a direct release of said propellant;
a mixing conduit within said case, said mixing conduit in fluid communication with said first component container, said second component container, and said propellant and configured to receive at least one of said first and said second foam components and cause mixing thereof and said propellant;
and
at least one nozzle operably connected to said case, said at least one nozzle in fluid communication with said mixing conduit and configured to spray at least one of said mixed first and second foam components and said propellant into said fire zone.

6 more elements

A removable fire suppression system for a fire zone, said fire suppression system comprising:

an exterior case including a bottom and at least one side defining an interior volume;
a first component container mounted within said interior volume, said first component container containing a first component of a two-part fire retardant agent;
a second component container mounted within said interior volume, said second component container containing a second component of said two-part fire retardant agent;
at least one component release device mounted within said interior volume, said at least one component release device in fluid communication with said first component container and said second component container, said at least one component release device being configured to be selectively capable of releasing at least one of said first and second components from said first and second component containers and a propellant;
a fire detector operably connected to said exterior case, said fire detector in electric communication with said at least one component release device, wherein said fire detector electronically signals for the release of at least one of said first and said second components and said propellant upon detection of smoke and/or heat;
wherein said propellant is in fluid communication with said first and said second components, wherein the activation of said at least one component release device results in at least one of (i) a unrestrained positive pressure applied upon said first component and said second component by said propellant thereby causing the exit of said first component from said first component tank container and the exit of said second component from said second component container and (ii) a direct release of said propellant;
a mixing conduit within said interior volume, said mixing conduit in fluid communication with said first and second component containers and said propellant and configured to receive at least one of said first and said second foam components and cause mixing thereof and said propellant;
and
at least one nozzle operably connected to said exterior case, said at least one nozzle in fluid communication with said mixing conduit and configured to spray at least one of said mixed first and second components and said propellant into said fire zone.
