CLEANING DEVICE FOR TUBULAR FILTER ELEMENTS

摘要

Disclosed is a device for tubular filter elements which extend from the separating floor of a dust filter into the dust-laden air chamber thereof and several of which are combined to form a group that is jointly inserted in the separating floor. A pneumatic pipe (11) is disposed above the outlet ports of the filter elements. Injectors (14) are flowably connected to said pneumatic pipe (11) so as to discharge a jet of compressed air into the outlet ports of the filter elements, which are disposed underneath. In order to create a cleaning device with a reduced loss of flow during the cleaning process, resulting in the filter elements being rinsed in a more efficient manner, an injector (14) which is directed into the outlet port (15) of the filter element (5) is positioned above each filter element (5) of the group. The injectors (14) which are assigned to the group of filter elements (5) are disposed on the floor (13) of a common distribution chamber (12) that is connected to the pneumatic pipe (11).
