Abstract

Invenţia se referă la un stingător cu spumă care foloseşte, ca substanţă de stingere, o substanţă fluorurată de tip AFFF, respectiv spumant cu formare de film apos şi realizează o spumă aeromecanică prin trecerea soluţiei de substanţă de stingere printr-un dispozitiv de producere a spumei (2). Sub acţiunea unei presiuni, obţinută dintr-o butelie de CO(3), se realizează spargerea membranei rezervei de substanţă de stingere (6). După omogenizare prin agitare, se deschide un robinet (5) şi substanţa stingătoare este antrenată, printr-un tub (4), într-un sistem de duze (9 şi 10), după care, prin creşterea presiunii dinamice, se realizează scăderea presiunii statice în zona unor prize de aer (11). Soluţia începe să treacă în stare de spumă şi, prin impactul în crucea de înfoiere (12), se realizează spuma aeromecanică. Datorită obţinerii unui regim turbulent de curgere în sistemul de duze, întreaga cantitate de soluţie spumantă trece în stare de spumă.The invention relates to a foam extinguisher which uses, as an extinguishing agent, a fluorinated substance of the type AFFF or an aqueous film-forming foam and produces an aeromechanical foam by passing the extinguishing solution solution through a foam-producing device (2). Under pressure, obtained from a CO (3) cylinder, breakdown of the extinguishing agent reservoir (6) is performed. After stirring, a tap (5) is opened and the extinguishing substance is entrained through a tube (4) into a nozzle system (9 and 10), after which, by increasing the dynamic pressure, pressure drop is achieved static in the area of some air inlets (11). The solution starts to penetrate and, by impact in the paving cross (12), the aeromechanical foam is made. Due to the turbulent flow in the nozzle system, the whole amount of the foam solution goes into foam.
