FOAM GENERATOR OF EJECTION TYPE Russian patent published in 2013 - IPC A62C31/00 

Abstract RU 2497561 C1

FIELD: fire-fighting facilities.

SUBSTANCE: invention is used in automatic fire-extinguishing systems by generating high-expansion polydisperse foam. The foam generator of ejection type comprises a sprayer, a foam nozzle and a distributor of two-phase flow. The sprayer is formed vortex type, which is connected with the foam nozzle housing. The nozzle housing is made in the form of a cylindrical shell and is mounted coaxially and axially relative the sprayer. On the foam nozzle housing, the windows are made for ejecting air. At the output of the housing the distributor of two-phase flow is fixed. In the middle part of the foam nozzle housing, the conical surface of the diffuser is attached with its large base, on which the windows are made for ejecting air. The smaller base of the truncated conical surface of the diffuser is fixed to the outlet of the sprayer. The sprayer consists of a sleeve on which one side the partition is located perpendicular to its axis. The partition is connected to the inlet of the fitting for supplying foam generating and fire extinguishing solution into the vortex chamber. The chamber is mounted on the inner surface of the sleeve of the sprayer and is formed as a cylindrical cavity with tangential openings. The cylindrical cavity is formed by the foam nozzle ring and two partitions, one of which is directed towards the fitting, is made solid, and the other is directed towards the diffuser - with the outlet.

EFFECT: increased efficiency of spraying of fire-extinguishing foaming agent.
