Abstract

1,211,094. Air filter. H. NIELSEN & SON MASKINFABRIK A/S. 8 Nov., 1967 [8 Nov., 1966], No. 50901/67. Heading B1T. A filter for removing solids from smokeladen air comprises a plurality of open-ended, outward flow fabric filter tubes 5 extending from air inlet chamber 4 to solids outlet hoppers 17 and enclosed by a chamber which is divided into sections 10. Each section communicates with a downstream fan 14 by a passage 11 or 12 which is selectively closable by a pivoted or sliding damper (Figs. 3, 4, not shown) which also controls an opening to atmosphere. By closing one passage at a time and allowing ambient air to be drawn into that section by the generally sub-atmospheric pressure in the filter, the tubes therein are cleaned and shaken by the reverse flow. Dampers may be operated manually or mechanically from a central point, and may each be shifted several times to shake tubes repeatedly. Before restoring normal filtering flow to a section, other dampers 28 are opened so that ambient air carries any dust from the downstream sides of sections 10 up into inlet chamber 4. Dust passes from hoppers 17 into bags 18 or onto a conveyor belt. The temperature of incoming air is boosted by hot air from an oil burner 8. Filtered air is discharged into chimney 16.
