Abstract

The apparatus has at least one container. This has an inner wall part which separates a crude gas space from a clean gas space and holds filters projecting into the crude gas space as well as wet cleaning devices which have a displaceable spray member with a rotatable spray head having liquid outlet holes. During normal operation of the apparatus, process gas is passed through the container and the filters, the filters removing dust from the process gas and each spray member being present in a rest position and being flush with a surface of the wall part, which surface is adjacent to the crude gas space. The spray members are displaced into the crude gas space for wet-cleaning of the filters and then sprayed with cleaning liquid against the filters, the wet cleaning devices not connecting the crude gas space to the clean gas space in any position of the spray members.
