Abstract

Proceso y dispositivo para limpiar gas de horno. Fluyendo en una dirección de flujo principal (A), el gas de horno pasa por un conjunto de filtros de saco (13). El gas de horno filtrado que ha pasado por los filtros de saco, se devuelve parcialmente a través de una o más boquillas (28) que se mueven a lo largo de los extremos aguas abajo de los filtros de saco. Cada filtro de saco (13) pasa al menos una vez por al menos una boquilla (28) durante un ciclo. Una boquilla que pasa por un filtro de saco inyecta gas de horno filtrado en una dirección de contraflujo (B) a través de dicho filtro de saco. La dirección de contraflujo es opuesta a la dirección de flujo principal.
