Abstract
A filter or catalyst body comprising wires or fibers is disclosed which is constructed in a single-layer or multi-layer as woven cloth, braiding or knitted fabric, the wires or fibers being at least partially connected to one another by sintering or welding. The woven cloth, netting, braiding or knitted fabric is endowed with inserted powdery, granular or chip-like particles which are sintered with or welded to the wires or fibers to provide a filter density which is lower in the inlet region of the filter body since fewer particles are provided there.
Claims21
A filter or catalyst body comprising wires or fibers constructed in one or several layers as woven cloth, braiding or knitted fabric, with the wires or fibers being at least partially connected to one another by sintering, said body containing inserted powdery, granular, or chip-like particles which are sintered with the wires or fibers, and said body having a lower filter density in the inlet region of the body than in other regions of the body by the provision of fewer particles in said inlet region than in said other regions.
A filter having a filter body comprising a plurality of braided layers including wires or fibers at least partially connected to one another, said body containing a plurality of inserted particles which are fixedly attached to the braided layers, and said body having a lower filter density in the inlet region of the filter body than in other regions of the body by the provision of fewer particles in said inlet region than in said other regions.
A filter having a filter body comprising a plurality of braided layers including wires or fibers at least partially connected to one another, said body containing a plurality of inserted particles which are fixedly attached to the braided layers, and said body having a higher filter density in the inlet region of the filter body than in other regions of the body wherein the filter density decreases in the outlet region of said filter body with a decrease in the allocation of particles in said outlet region.
