Abstract

It is comprised of a support (1) which has internally the extinguisher itself, as fire preventing element, a plurality of them being placed repeatedly and regularly on the edge of the gutter (4) of the floating roof of the tank (3). This gutter embodies the junction ring of the elastic which is part of said floating roof. The automatic explosion of the extinguishers puts out the fire by covering it with foam which seals and presses the elastic against the wall of the container tank. The supports incorporate wicks of a pyrotechnic warning system.

Los soportes están uniformemente distribuidos a la distancia conveniente y pueden incorporar un sistema pirotécnico para que cuando se produzca la explosión, ésta sea oída por los operarios de la planta. El soporte incluye dos placas paralelas: una superior y otra inferior, vinculadas por la parte delantera por una pareja de barras metálicas, en tanto que posteriormente incluye una plancha que se prolonga arqueadamente por los laterales para sujetar el extintor y a su vez actuar como deflector que permite que el producto extintor dispersado pueda ser controlado y dirigido.The supports are uniformly distributed at a convenient distance and can incorporate a pyrotechnic system so that when the explosion occurs, it is heard by the plant's operators. The stand includes two parallel plates: one upper and lower, linked by the front by a pair of metal bars, while subsequently includes an iron that extends arched on the sides to hold the extinguisher and in turn act as a baffle that allows the dispersed extinguishing product can be controlled and directed.

En el interior del soporte se encuentra el extintor o dispositivo de extinción y prevención de incendios, consistente en un recipiente contenedor del producto de extinción y de una carga explosiva en comunicación directa con una mecha que emerge al exterior del recipiente.Inside the support is the extinguisher or fire prevention and extinguishing device, consisting of a container containing the extinguishing product and an explosive charge in direct communication with a wick that emerges outside the container.

El producto de extinción es ventajosamente espuma para sellar la abertura que pueda determinarse entre el aro del techo flotante y la pared del depósito o tanque contenedor del producto inflamable, sofocando totalmente el fuego al cubrirlo de espuma y oprimir el elástico del techo flotante contra la pared del contenedor.The extinguishing product is advantageously foam to seal the opening that can be determined between the hoop of the floating roof and the wall of the deposit or container tank of the flammable product, totally quenching the fire when covering it with foam and pressing the elastic of the floating roof against the wall of the container
