Abstract

Procedimiento para la limpieza de elementos de filtro, de tela, a modo de manga, en un aparato neumático de extracción de polvo por flujo de aire inverso a través de respectivas aberturas libres, en cada uno de dichos elementos de filtro en dirección inversa y corriente abajo respecto a la dirección de aire filtrado, caracterizado por incluir una fase de choque seguida inmediatamente de una fase de lavado; incluyendo dicha fase de choque el desprendimiento de una capa de polvo acumulado desde dicho elemento de filtro por la repentina aplicación de flujo inverso de aire de alta intensidad; de una breve duración, por lo que la tela de dicho elemento es vuelta desde una posición filtrante a una posición modificada; corriente arriba respecto a dicha posición filtrante; e incluyendo dicho fase lavadora la separación de por lo menos parte de las partículas restantes de polvo desde dicho elemento de filtro por la aplicación continuada de flujo de aire inverso de intensidad de flujo reducida y controlada, pero de mayor duració, mientras se hace retornar gradualmente dicha tela del citado elemento de filtro desde dicha posición modificada a la mencionada posición filtrante.
