FOAM GENERATOR Russian patent published in 2018 - IPC A62C31/12 B05B1/34 

FIELD: fire safety; fire engineering.

SUBSTANCE: invention relates to the field of fire-fighting equipment and is designed for use in automatic systems of fire-fighting by generation of a high-expansion polydisperse foam under conditions of room smoke screening by blockage of quick-burning products with a high-expansion polydisperse foam. In the foam generator, each of the spray nozzles consists of a cylindrical hollow body with a fluid supply channel, threaded portion and garter belt section. In the lower part of the cylindrical hollow body with a channel for supplying liquid, a hollow conical swirler is fixed. Conical shell of the swirler is fixed by means of at least three spokes fixed at one end to the conical shell of the swirler in its upper part and the other end to the annular groove formed on the inner surface of the fluid supply channel. On the surface of the hollow cone swirler a screw thread is made.

EFFECT: technical effect: higher efficiency of spraying a fire-fighting liquid solution of a foaming agent (a high-expansion polydisperse foam).
