Abstract
A device for cleaning a bag filter, closed on one side, is arranged on a supporting grid within a housing traversed by the fluid to be cleaned and is provided on the clean-gas side with an injector which is directed into the inside of the fabric filter and is connected to a source of gas of higher pressure than the pressure of the fluid to be filtered. In order to develop the breaking up of the filter cake upon the cleaning of fabric filters in such a manner that as few components as possible of the filter cake are placed in suspended condition and therefore the greatest possible proportion of the filter cake can be removed as a coherent unit, it is proposed that on the clean-gas side (14) of the supporting grid (2a) there be arranged a bag (3) which is expandable by gas pressure, the bag (3) be attached in pressure-tight manner to the injector (10) and the bag (3) be so dimensioned that its circumference corresponds at least to the inside circumference of the supporting grid (2a).
