Abstract
Disclosed herein is a filter apparatus comprising a fluid inlet for a fluid to be filtered in the apparatus; a first fluid outlet for fluid that has been filtered; and one or more barrier filters arranged between the fluid inlet and the first fluid outlet for filtering material from the fluid. In use, the fluid to be filtered is directed from the fluid inlet so as to promote a continuous erosion of material built up on the barrier filter(s). Also disclosed is a method of filtering particles from a particle laden fluid.
Claims12
A filter apparatus comprising:
- a fluid inlet for a fluid to be filtered in the apparatus;
- a first fluid outlet for fluid that has been filtered;
- a bank of barrier filters having a tubular configuration and arranged between the fluid inlet and the first fluid outlet for filtering material from the fluid;
- a distributor for causing the fluid entering the apparatus via the fluid inlet to flow over a surface of each barrier filter;
- and
- a compressor for directing the fluid through the fluid inlet such that the fluid flows around the barrier filter(s);
- wherein, in use, the fluid to be filtered is directed from the fluid inlet so as to promote a continuous erosion of material built up on the barrier filter(s) and wherein the distributor comprises a shell-type structure that interleaves with the barrier filter bank so as to promote a flow of the fluid to be filtered over a substantial portion of the barrier filters.
