ROBOTIC FIRE COMPLEX WITH NITROGEN-WATER FIRE EXTINGUISHING Russian patent published in 2011 - IPC B05B17/00 A62C37/00 

FIELD: fire-fighting means.

SUBSTANCE: robotic fire complex with nitrogen-water fire extinguishing refers to robotic fire fighting installations. Object of the invention is development of a system with considerably lowered water consumption, with applying alternative available fire extinguishing agent, with no capital intensive pump station, water supply source and switching station employed. For this purpose, the system additionally comprises a nitrogen generator and ejectors. The nitrogen generator is connected with a receiver containing nitrogen under working pressure, connected to a fire pipeline for nitrogen supply to fire monitors. The ejectors supply water to a nitrogen flow, are built in a flow part of fire monitor nozzles, connected to tapped containers.

EFFECT: considerable reduction of water consumption which is ejected in a small amount and sprayed into a nitrogen jet which represents in turn available effective fire fighting means filled up from air; besides, the invention allows avoiding applying in the system such permanent structures, as pump stations, water supply sources and switching stations.
