Abstract

EL DISPOSITIVO FILTRANTE PARA FILTRAR UNA CORRIENTE DE GAS, ESPECIALMENTE PARA FILTRAR EL GAS PRODUCIDO POR UN GENERADOR DE GAS PARA UN SACO DE GAS DE PROTECCION CONTRA IMPACTOS, PRESENTA UN ELEMENTO FILTRANTE, EL CUAL A SU VEZ PRESENTA EN DIRECCION A LA CORRIENTE, CAPAS DE MATERIAL FILTRANTE SUCESIVAS DE DISTINTA PERMEABILIDAD. EL ELEMENTO FILTRANTE SE HA CONCEBIDO COMO UN CUERPO ARROLLADO (38), EL CUAL SE HA CONSTITUIDO POR EL ENROLLAMIENTO DE BANDAS DE MATERIAL FILTRANTE. LA BANDA DE MATERIAL FILTRANTE PRESENTA SECTORIALMENTE DIFERENTES MATERIALES FILTRANTES, PREFERENTEMENTE TELA METALICA, DE DISTINTO ANCHO DE MALLA Y DE FIBRAS METALICAS. A CAUSA DEL ENROLLADO DE ESTA BANDA DE MATERIAL FILTRANTE SE ORIGINA UN CUERPO ARROLLADO (38), CUYAS ESPIRAS ESTAN COMPUESTAS DE MATERIALES DIFERENTES, CON DIFERENTE EFECTO FILTRANTE. ESTE CUERPO ARROLLADO FILTRANTE (38) ES INCORPORADO P.EJ. EN LA ZONA INTERMEDIA ANULAR, ENTRE LOS DOS TUBOS (12,14) DE UN TUBO DOBLE DE UN GENERADOR DE GAS. EN BASE AL AUMENTO DE LA PRESION DEL GAS A DEPURAR, SE COMPRIME EL CUERPO ARROLLADO (38), CON LA CONSECUENCIA DE QUE SE MEJORA LA FUNCION FILTRANTE.
