A plurality of elongated tubular porous bags are arranged in a straight line side by side in a housing through which a dirty stream of gas is passed impinging on the outer surfaces of the bags and thus collecting dirt particles there. In the middle of each bag, extending from end to end thereof, is an impervious linear partition dividing the interior of each bag into two non-communicating half portions. To clean the collected dirt off the outer faces of the bags, means is provided for discharging a cleaning stream of gas into two adjacent selected half portions of two different bags under sufficient pressure to pass outwardly through the half portions and dislodge the dirt collected on the outer faces of those half portions, while the apparatus continues to collect direct particles on the other bags including the other half-portions of the two bags currently being cleaned.

A method of cleaning bag collectors of dirt particles wherein a plurality of elongated tubular porous bags are arranged in a bag housing with their longer dimensions parallel and in a straight line side by side with means for passing a dirty stream of gas simultaneously through said bags radially inwardly, thus collecting dirt on the outer faces of said bags, means for discharging the clean stream of gas at an open end of said bags, a substantially impervious linear partition in the middle of each bag normal to said straight line dividing the inside of each bag into two non-communicating half portions extending from end to end of each bag and beyond said open ends of said bags to said means for discharging said clean stream of gas; comprising selectiVely closing said clean gas discharging means of two adjacent half portions of two of said bags, and selectively passing a cleansing stream of gas into the interior of said selected two adjacent half portions under sufficient pressure to pass outwardly through said two adjacent half portions and dislodge the dirt collected on the outer faces of said two adjacent half portions, while continuing to collect dirt particles on the other half portions of said two bags whereby the space between said two selected half portions is relatively quiescent and said dislodged dirt falls downwardly.
