IMPROVEMENTS IN DEVICES FOR THE PRODUCTION AND SPILLAGE OF EXTINGUISHING FOAM IN FIRE FIGHTING PLANTS OF HYDROCARBON TANKS

Abstract

Abstract Translated from French PERFECTIONNEMENTS AUX DISPOSITIFS POUR LA PRODUCTION ET LE DEVERSEMENT DE MOUSSES EXTINCTRICES DANS DES INSTALLATIONS DE LUTTE CONTRE L'INCENDIE DE CUVES D'HYDROCARBURE A TOIT FLOTTANT COMPRENANT UNE SERIE DE TUYAUX VERTICAUX DISPOSES REGULIEREMENT AUTOUR DE LA CUVE D'HYDROCARBURE ET DONT LES EXTREMITES SUPERIEURES LIBRES SONT POURVUES D'UN DIFFUSEUR 9, LESDITS TUYAUX ETANT RELIES A UNE SOURCE D'EAU SOUS PRESSION AVEC INTERPOSITION DE MOYENS D'INTRODUCTION D'UN AGENT EMULSIONNANT, CARACTERISES EN CE QUE LES DIFFUSEURS 9 COMPORTENT DEUX BECS 20, 21 QUI FORMENT UN ANGLE ENTRE EUX ET DONT LES EXTREMITES LIBRES SONT DIRIGEES VERS LE TOIT FLOTTANT, CHAQUE BEC 20, 21 COMPORTANT UNE FENTE LONGITUDINALE 28 DANS SA PARTIE OPPOSEE A SON EXTREMITE LIBRE ET TOURNEE VERS LE TOIT FLOTTANT. IMPROVEMENTS IN THE DEVICES FOR THE PRODUCTION AND DISCHARGE OF FIRE EXTINGUISHING FOAMS IN FIRE FIGHTING SYSTEMS OF OIL TANKS WITH A FLOATING ROOF INCLUDING A SERIES OF VERTICAL PIPES REGULARLY ARRANGED AROUND THE HYDROCARBON TANKS AND SUPERCARBON EXIBRATION AROUND THE TANK. ARE EQUIPPED WITH A DIFFUSER 9, THE SAID PIPES BEING CONNECTED TO A SOURCE OF WATER UNDER PRESSURE WITH THE INTERPOSITION OF MEANS OF INTRODUCING AN EMULSIONING AGENT, CHARACTERIZED IN THAT THE DIFFUSERS 9 HAVE TWO NOZZLES 20, 21 WHICH FORM AN ANGLE BETWEEN THEM AND WHOSE FREE ENDS ARE DIRECTED TOWARDS THE FLOATING ROOF, EACH BEC 20, 21 INCLUDING A LONGITUDINAL SLIT 28 IN ITS OPPOSITE PART OF ITS FREE END AND TURNED TOWARDS THE FLOATING ROOF.
