FIELD: process engineering.
SUBSTANCE: invention relates to gas filtration. Fabric filter has at least first and second compartments. Bin allows fluidisation of dust accumulated in compartments for formation of fluidised dust layer. Separating plate is arranged between compartments to isolate them. Channel is made at lower end of said separating plate to allow fluidised dust flow through said channel. Separating plate is arranged to extend into fluidised dust layer to produce seal even with one compartment disconnected. With compartment disconnected, its inlets and outlets are closed for bin dust to be fluidised to produce seal between compartments.
EFFECT: reduced capital and operating costs.
