METHOD AND APPARATUS FOR SEPARATING PARTICULATE MATTER FROM GASES Inventor: Joseph G. Wilson Abstract of the Disclosure A centrifugal separator has an outer tube and an inner tube concentrically positioned therein, forming an annular gas inlet channel between the outer and inner tubes, and slots are defined in the inner tube to provide communica- tion between this annular channel and the space within the inner tube. A collection chamber for collecting particulate matter and for allowing the flow of bleed gases is provided towards the bottom of the annular channel. Transverse dis- charge means communicate with the collection chamber for removing material therefrom. The separator includes at least one swirling vane for imparting swirling motion to gas flowing in the annular channel. Separation of particulate matter from the swirling gas due to centrifugal force occurs when the gas initially enters the annular channel and as the gas swirls within the annular channel. Further separation of particulate matter occurs when the swirling gas in the channel experiences a sudden change in flow direction during entering the slots in the inner tube. Clean gas discharge means are provided at the bottom of the inner tube so that clean gas exits the separator from below. A plurality of such centrifugal separators are mounted in a pair of upper and lower parallel tube sheets located within a separator vessel. The tube sheets define a main separation chamber therebetween, with a gas inlet chamber thereabove, and a clean gas discharge chamber therebelow. Gas containing particulate matter enters the inlet chamber of the vessel from above, passes directly into the multiple separators in the separation chamber, and is discharged downwardly through the bottom discharge chamber. Means to remove separated particulate matter and bleed gas from the separation chamber are provided. -2-
