Abstract
A dust filter has a vertically oriented filter housing and a partition dividing the filter housing into a lower dust-contaminated air chamber and an upper clean air chamber. The partition has a plurality of openings. Self-supporting filter tubes are suspended from the openings and extend into the lower dust-contaminated chamber, wherein the self-supporting filter tubes are open upwardly in a direction toward the clean air chamber. Several self-supporting filter tubes are combined to a filter bundle, respectively, wherein a spacing between the self-supporting filter tubes of each filter bundle is smaller than a spacing of the filter bundles relative to one another. A device for cleaning off dust and product particles adhering to outer surfaces of the self-supporting filter tubes is provided.
Claims22
A dust filter comprising:
- a vertically oriented filter housing (1);
- a partition (2) dividing the filter housing (1) into a lower dust-contaminated air chamber (3) and an upper clean air chamber (4), wherein the partition (2) has a plurality of openings;
- self-supporting filter tubes (5) suspended from the openings and extending into the lower dust-contaminated chamber (3), wherein the self-supporting filter tubes (5) are open upwardly in a direction toward the clean air chamber (4);
- wherein several self-supporting filter tubes (5) are combined to a filter bundle (7), respectively, wherein a spacing between the self-supporting filter tubes (5) of each one of the filter bundles (7) is smaller than a spacing of the filter bundles (7) relative to one another;
- and
- means (10, 16) for cleaning off dust and product particles adhering to outer surfaces of the self-supporting filter tubes (5);
- wherein the means for cleaning comprises a compressed air pulse injector having compressed air sources (10) arranged in the clean air chamber (4) above the filter bundles (7), respectively, and configured to remove by compressed air pulses the dust and product particles adhering to the outer surfaces of the filter tubes (5);
- and
- catch nozzles (13) arranged at a top side of the partition and surrounding the self-supporting filter tubes (5) of the filter bundles (7), respectively, wherein the catch nozzles (13) are configured to concentrate the compressed air of the compressed air pulse injector system onto the self-supporting filter tubes (5) of the filter bundles (7).
