Abstract

MEDIOS DE FILTRO USADOS PARA EXTRAER MATERIAS EXTRAÑAS DE UNA CORRIENTE DE AIRE QUE FLUYE A SU TRAVES, CUYOS MEDIOS INCLUYEN UN PAR DE LAMINAS PRIMERA Y SEGUNDA, GENERALMENTE PLANAS, DE MATERIAL FILTRANTE, QUE SE EXTIENDEN EN RELACION PARALELA LA UNA RESPECTO A LA OTRA, CON UN ESPACIAMIENTO ENTRE ELLAS. LAS LAMINAS PRIMERA Y SEGUNDA ESTAN CADA UNA FORMADA POR UNA PLURALIDAD DE CONCAVIDADES QUE SE EXTIENDEN, RESPECTIVAMENTE, HACIA DENTRO, HACIA LA OTRA DE LAS LAMINAS, LIMITANDO EN ELLA PARA MANTENER EL ESPACIAMIENTO ENTRE LAS LAMINAS, Y LAS CONCAVIDADES ESTAN ESPACIADAS EN UNA DE LAS LAMINAS UNAS DE OTRAS, A LO LARGO DE LA LONGITUD DE LAS MISMAS, Y TAMBIEN ESPACIADAS DESDE LAS CORRESPONDIENTES CONCAVIDADES EN LA OTRA LAMINA, SIENDO IGUAL PREFERENTEMENTE TAL ESPACIAMIENTO. DEL MISMO MODO, PARES ADYACENTES DE TALES LAMINAS DE MEDIOS DE FILTRO ESTAN SITUADAS EN TAL FORMA QUE LAS CONCAVIDADES EN LAS SUPERFICIES ENFRENTADAS DE PARES ADYACENTES ESTAN DESVIADAS UNAS DE OTRAS, CON LO QUE AGLUTINACIONES DE MATERIAS EXTRAÑAS NO TIENDEN A ACUMULARSE, Y QUEDAN SUJETAS EN FISURAS OPUESTAS FORMADAS POR LAS CONCAVIDADES.
