Abstract

In an apparatus for filtering gases with a closed container which is divided by a horizontal perforated plate into a lower compartment provided with a gas inlet and an upper compartment provided with a gas outlet, and with tubular or candle-shaped filter elements which are sealingly suspended in holes of the perforated plate and are supported by a flange-type enlargement at their upper end on the perforated plate, in order to also ensure reliable sealing during swivel motion of the filter elements relative to the perforated plate, it is proposed that the flangetype enlargement form a bearing surface which lies on the surface of a sphere with center point above the bearing surface and on the vertical center axis of the filter element, and that the hole in the perforated plate so surround at a distance the filter shell of the filter element downwardly adjoining the enlargement that the filter element can swivel over a certain angular range about the center point of the sphere.
