Abstract
(EN)
A dust removal apparatus of outside filter bag type and a method for removal of dust from the dust removal apparatus are provided. The dust removal apparatus of outside filter bag type includes a housing (2), inside which a cell plate (5) are provided. The cell plate (5) fastens filter bags (6). The bag-cages (61) are inserted into the filter bags (6). The bag cages (61) support the filter bags (6) firmly. The dust removal apparatus of outside filter bag type further includes a reverse blow unit for providing a reverse-air flow with stable pressure while removal of dust. The method for removal of dust includes steps as follow, blowing reverse-air flow with stable pressure into filter bags firstly; cutting off the reverse-air flow after prescriptive time.

L'invention concerne un appareil pour retirer la poussière de type à sac de filtre externe et un procédé pour retirer la poussière de l'appareil pour retirer la poussière. L'appareil pour retirer la poussière de type à sac de filtre externe comprend un boîtier (2), qui est équipé à l'intérieur d'une plaque cellulaire. La plaque cellulaire (5) fixe les sacs de filtre (6). Les gaines de sac (61) sont insérées dans les sacs de filtre (6). Les gaines de sac (61) supportent fermement les sacs de filtre (6). L'appareil pour retirer la poussière de type à sac de filtre externe comprend en outre une unité de soufflage inversé pour fournir un courant d'air inversé avec une pression stable en retirant la poussière. Le procédé pour retirer la poussière comprend les étapes suivantes, souffler le courant d'air inversé avec une pression stable dans les sacs de filtre en premier lieu; couper le courant d'air inversé après le temps prescrit.
