Abstract

La présente invention concerne un épurateur d'air poussiéreux portatif modulaire comprenant un bac amovible, un distributeur de gaz impur, une plaque à ouvertures, une pluralité de filtres tubulaires, un toit, une chambre à gaz pur, une chambre de collecte de poussière, et un ensemble à jet d'impulsion. Le distributeur de gaz impur est positionné de manière à distribuer un gaz impur dans la chambre de collecte de poussière à partir une périphérie de la pluralité de filtres. Le bac amovible dépend du distributeur de gaz sale. La plaque à ouvertures forme au moins un plafond partiel pour le bac. La pluralité de filtres tubulaires est suspendue dans le bac par les ouvertures de la plaque à raison d'un filtre par ouverture. Le toit est positionné au-dessus de la plaque à ouvertures. La chambre à gaz pur est délimitée entre la plaque et le toit. L'ensemble à jet d'impulsion est positionné au moins en partie dans la chambre à gaz pur. L'ensemble à jet d'impulsion comprend une pluralité de buses pour pulser des jets de gaz vers le bas en direction de la pluralité de filtres, à raison d'une buse par filtre pour déloger la poussière accumulée dans le bac amovible.
