Abstract
Abstract A gas separation apparatus is provided for removing moistened particles from a stream of air by subjecting the moistened particle laden air stream to centrifugal force to separate the moistened particles from the air stream and thence separating the water from the particles and finally causing the air stream to pass to an outlet through a mechanical separator assembly to remove any particles still remaining therein.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
170 words
A gas separator apparatus comprising: a generally cylindrical housing rotatable about a central axis and defining a main separating chamber; a dirty gas inlet communicating with the interior of said housing; means within said housing for increasing the radial velocity of the dirty gas introduced into said housing through said gas inlet; stationary fluid intake passage means extending radially outwardly of the central axis of said housing into the main separating chamber, said passage means including a fluid intake opening at the outermost end thereof, and a fluid outlet in communication with the opposite end thereof; stationary particulate intake passage means extending radially outwardly of the central axis of the housing into the main separating chamber, said passage means including a particulate intake opening at the outermost end thereof, and a particulate outlet in communication with the opposite end thereof; a clean gas outlet; and an impingement plate separator disposed between the interior of said housing and said clean gas outlet for mechanically removing particles from the gas being treated.
Claim 2
Dependent Claim
170 words
A gas separator apparatus comprising: a generally cylindrical housing rotatable about a central axis and defining a main separating chamber; a dirty gas inlet communicating with the interior of said housing; means within said housing for increasing the radial velocity of the dirty gas introduced into said housing through said gas inlet; stationary fluid intake passage means extending radially outwardly of the central axis of said housing into the main separating chamber, said passage means including a fluid intake opening at the outermost end thereof, and a fluid outlet in communication with the opposite end thereof; stationary particulate intake passage means extending radially outwardly of the central axis of the housing into the main separating chamber, said passage means including a particulate intake opening at the outermost end thereof, and a particulate outlet in communication with the opposite end thereof; a clean gas outlet; and an impingement plate separator disposed between the interior of said housing and said clean gas outlet for mechanically removing particles from the gas being treated.
Claim 3
Dependent Claim
22 words
The invention defined in claim 1 wherein said particulate intake opening is disposed in the region of the periphery of said housing.
Claim 4
Dependent Claim
19 words
The invention defined in claim 1 wherein said impingement plate separator includes an annular array of spaced apart plates.
Claim 5
Dependent Claim
14 words
The invention defined in claim 3 wherein said separator is rotatable with said housing.
Claim 6
Dependent Claim
23 words
The invention defined in claim 3 wherein said plates are planar and are generally normal to the axis of rotation of said housing.
Claim 7
Dependent Claim
41 words
The invention defined in claim 1 wherein the fluid intake opening of said fluid intake passage means and the particulate intake opening of said particulate intake passage means extend in a direction opposite to the direction of rotation of said housing.
