MODULE FOR FIRE SUPPRESSION WITH DISPERSED LIQUID AND LIQUID DISPERSER Russian patent published in 1999 - IPC

FIELD: fire fighting equipment, in particular, suppression of fire by means of gas propelled liquid such as water. SUBSTANCE: module has balloon filled with fire suppressing liquid and compressed gas, siphon tube positioned within balloon and having channel with reduced section and through side openings made in this channel and adapted for communication with balloon gas cavity. Module is further provided with locking and starting device connected with siphon tube and liquid disperser communicated via locking and starting device with siphon tube. To enhance uniform dispersion of liquid in premises to be protected from fire, siphon tube is composed of two parts interconnected so that part with enlarged section is positioned in balloon gas cavity. Effective section area of side openings made in siphon tube junctions is from 0.03 to 0.1 of effective section area of siphon tube part positioned in gas cavity. Liquid dispersing openings in disperser body are arranged in axially aligned successive rows. Annular conical deflector is positioned on outer surface of disperser body in front of terminating row of openings with respect to liquid supply branch pipe. Top part of conical surface of deflector is positioned adjacent to gas-liquid flow supply side. EFFECT: increased efficiency and enhanced reliability in operation. 9 cl, 1 dwg, 1 tbl
