METHOD FOR ATTENUATING THERMAL GAS FLOWS AND USMANOV'S DEVICE FOR REALISING THE SAME

Document Type and Number:

WIPO Patent Application WO/2000/066227

Kind Code:

A1

Abstract:

The present invention pertains to the field of fire-fighting technology and can be used for protecting equipment and persons when extinguishing fires, for dividing the volume of buildings in surface or underground structures or installations into fire-proof compartments, for providing protection against the collapse of ceiling structures and for locating the progression of the flame front in large-scale fires resulting in ecological disasters. The purpose of this invention is to develop a method for attenuating with an improved efficiency the energy flow consisting of light, heat and convection gas flows, and to develop a device of the gun-carriage type for creating a thermal-radiation protection screen which is more reliable, harmless and easy to implement and which provides protection against light radiation and convection gas flows. This method involves creating a curtain of a cooling liquid that is sprayed into space between surfaces. When creating more than one curtain, the method involves using a combined supply of cooling liquid. One of the curtains is formed by spraying the liquid, while the following curtains are formed by supplying an aerated mechanical or chemical foam. The device includes a mounting assembly, a spraying unit as well as grids arranged on both sides of a frame so as to define a gap. Nozzles are further mounted in the openings formed in the tubes of the frame.
