ADVANCED TECHNOLOGY OF PRODUCTION OF FOAM WITH COMPRESSED AIR Russian patent published in 2012 - IPC A62C5/02 

FIELD: fire-fighting means.

SUBSTANCE: method is proposed for continuous creation of foam with compressed air, particularly for fire fighting or for disinfection by filing two components: a compressed air and a mixture of water and at least a foam-forming agent in a chamber for foam forming, and this foam is taken out into the tip through the pipeline. Each of the components: a mixture of foam-forming agent and water and compressed air is continuously fed into the chamber for foam-forming at constant pressure and constant volume flow, for example, through pressure regulators and flow rate controllers. The pressure of the foam is adjusted in the outlet of the chamber for foam-forming to maintain a constant pressure of mixing foam in the chamber for foam-forming, preferably via an automatic valve. The chamber for foam-forming may preferably be a chamber of static type, containing grids.

EFFECT: invention provides a simple implementation of creation of foam with compressed air, preferably with a compressed gas, with a high and consistent quality.
