FIRE SUPPRESSION SYSTEM

摘要

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.

1. A fire suppression system for a fire zone, said fire suppression system comprising:
an exterior case including a removable top lid, a bottom, a first side, a second side, a front and a back, said top lid, said bottom, said first side, said second side, said front and said back defining an interior volume; a first component container mounted within said interior volume of said exterior case, said first component container containing a first liquid foam component of a two-part foam; a second component container mounted within said interior volume of said exterior case, said second container containing a second liquid foam component of said two-part foam; 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 said first and second components from said first and second component containers; a fire detector operably connected to said top lid of 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 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 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; a mixing conduit within said interior volume, said mixing conduit in fluid communication with said first component container and said second component container and configured to receive said first and said second foam components and cause mixing thereof; 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 said mixed first and second foam components into said fire zone.
