Abstract

1354261 Separating and collecting particles from gases 2000 Inc 19 April 1971 [10 March 1970] 9884/71 Heading BIT A device for collecting dust and smoke particles from air or other gases comprises a container 10 having an inlet and an outlet 34, 30 and a series of spaced, apertured plates 40. The apertures progressively decrease in size from the inlet to the outlet and the apertures of adjacent rows are staggered to impart a sinusoidal flow path such that the abrupt changes of gas flow path cause the particles to be thrown out of the gas stream and impinge on the subsequent plate. The apertures may be arranged in circles. The gas velocity is increased each time it passes through a plate.
