Abstract
The apparatus has a container, which encloses a crude gas space, and at least one filter projecting into the crude gas space and having a filter axis and a shape-stable casing. This has a support member with two wire fabrics and a filtration member which forms its outer surface and has a wire fabric. The wire fabrics of the support member and of the filtration member are rotationally symmetrical with the filter axis, are adjacent to one another and are sintered with one another at the points of contact. When process gas is passed from the crude gas space through a filter, the process gas deposits dust present in it onto the outer surface of the casing. The or each filter is stable, durable and resistant to high or low temperatures and can be readily cleaned inside the container with a cleaning gas or a cleaning liquid.
