Abstract

1,229,952. Gas filters. INTENSIV-FILTER G.m.b.H. 24 May, 1968 [2 June, 1967], No. 24842/68. Heading B1T. Dust is removed from a gas by means of a plurality of tubular fibre filter elements 16 suspended from a resiliently loaded support plate 17 in a housing 10 having a crude gas inlet 13, an outlet 15 for clean gas and a flushing gas housing 26. To clean the elements (Fig. 2, not shown) backflushing is commenced (as shown, by closing aperture 14 and opening aperture 27); and a chamber A, defined by a beater plate 19 and flexible sealing means 21, is subjected to negative pressure pulsations so causing plate 19 to reciprocate and a hammer 20 to strike plate 17, thus shaking the filter elements. Dust from elements 16 falls into worm 12 and is discharged. As described, a leaf spring 30, for returning plate 19, is provided. A pipe 23 connects chamber A to the outlet 15 which is at subatmospheric pressure. Pulsations are produced by means 24, 25 which block pipe 23 and open chamber A to atmosphere. Reference has been directed by the Comptroller to Specification 1,029,373. 1,119,545.
