Abstract

1414049 Dust filter HEINRICH LUHR VDI STAUBTECHNIK 27 March 1973 [28 March 1972] 14788/73 Addition to 1387485 Heading BIT The parent Specification 1387485 is modified in that the gas filter for removing fine dust from an air stream using recycled agglomerated filtered dust retains the dust within the filter. The dust blown by a moving nozzle from the filter bags falls in.to the incoming dust laden air in trough 14 and agglomerates further fine dust and is carried back by the air flow onto the filtering surfaces repeatedly, and a portion of dust, equal in quantity/unit time with the input dust is discharged (through rotary valve 9). Discharge means may include an auger or a fluidised bed using a porous angled intermediate floor (23) (Fig. 6 not shown). The dust input may be either from the top or bottom of the housing 1, the gas flowing upwardly and inwardly through the filter bag walls and out at (16).
