Abstract

a presente invenção refere-se à processo e a um dispositivo para a limpeza de gas de alto-forno. fluindo em uma direção de fluxo principal (a) o gas de alto-forno passa em uma matriz de saco de filtro (13). o gás de alto-forno filtrado, tendo passado os sacos de filtro, é parcialmente devolvido através de um ou mais bicos (28) que são movidos ao longo da extremidade a jusante do saco de filtro. cada saco de filtro (13) é passado pelo menos uma vez por pelo menos um bico (28) durante um ciclo. um bico passando um saco de filtro sopra o gás de alto-forno filtrado em uma direção de refluxo (b) através do dito saco de filtro. a direção de refluxo é oposta a direção de fluxo principal.
