Abstract

1383769 Gas filter KOCKUMS MEKANISKA VERKSTADT AB 30 June 1972 [2 July 1971] 30880/72 Heading BIT To clean the gas filter bags 12, the open ends of the bags are closed by lowering plates 20, and sound vibrations are generated inside the bags by means 11 attached to plates 20, which shakes the bags while minimising noise outside the filter housing. In Fig. I plates 20 are lowered by delivering gas to bellows 18, and as the gas pressure rises further this gas aatuates the pneumatic diaphragm valve sirens 11 and escapes into bags 12 to assist cleaning thereof by reverse flow. In Fig. 2 (not shown) the bellows have separate gas supplies so that bags can be cleaned singly or in groups while the others continue to filter. The housing may be lined with mineral wool to reduce external noise, but as shown section 2 is of concrete. The plates could alternatively be moved mechanically, and the means 11 could be electrically powered.
