Abstract
Abstract In this apparatus, a stream of gas having particles of dust is subjected to a change of direction such as, for example, a 90* turn. As the stream of gas is turned, the particles of dust which are suspended in the gas, and being heavier than the gas, tend to collect and form a lamina of dust particles along the inner surface of the wall forming the outside curve of the turn through the action of centrifugal force. The lamina of dust particles is deflected out through an opening in the wall forming the outside curve of the turn, and the clean air which is positioned adjacent the inside curve of the turn is directed passed the opening.

Claim 1
Independent Claim
182 words
Apparatus for separating dust from a stream of gas, which comprises: a continuously curved gas separation chamber having an inner wall and an outer wall and a cross sectional configuration that is wider than it is deep, said chamber including an inlet opening at one end thereof for receiving a stream of gas containing dust, an outlet opening at the other end thereof for discharging gas and an aperture provided in the outside wall adjacent the outlet opening, a first blade mounted in the aperture for separating dust from the stream of gas, a second blade mounted in the aperture upstream of the first blade for separating dust from the stream of gas, means to pivot said first blade to change its angle relative to the direction of flow of the stream of gas, means to pivot said second blade to change its angle relative to the direction of flow of the stream of gas, means for moving said first and second blades in unison, and an exhaust compartment communicating with the aperture to receive dust separated from the stream of gas.
