The invention relates to a cleaning device for cleaning filter bags in a filter system. Each cleaning device is associated with one of the several filter bags that are suspended in a separating floor of the filter system, respectively. Each cleaning device has a cleaning gas supply which can be activated by means of a valve and which opens into a ring channel with a cleaning gas exit gap. The aim of the invention is to improve a device of this type in such a way as to ensure that the entire length of the respective filter bag is cleaned. To this end, a nozzle body (8) is located underneath the cleaning gas exit gap (10). The cross-section of this nozzle body is configured in such a way that starting from an upper curvature which has a crown area (11) in an area of the cleaning gas exit gap (10), the lateral surfaces extend at an acute angle to each other in a tip (12), the inner path from the upper crown area (11) to the tip (12) being longer than the outer path. |
