Patent ID: 7144437

Claim:
A vertically oriented separator for separating liquid from a gas stream, said separator comprising an inlet nozzle ( 121 , 221 , 321 ) arranged mainly perpendicularly to the centre axis of the separator and communicating with a circular swirl-inducing inlet device ( 101 , 201 , 301 ) being outwardly limited by the separator wall ( 103 , 203 , 303 ), inwardly limited by a mainly centrally arranged pipe ( 117 , 217 , 317 ) and upwardly limited by a sealed top cover ( 122 , 222 , 322 ); a first separation compartment ( 112 , 212 , 312 ) arranged below the pipe ( 117 , 217 , 317 ); a second separator compartment ( 123 , 223 , 323 ,) arranged above the pipe ( 117 , 217 , 317 ), so the incoming fluid successively and under continuous swirl is forced to pass from the circular swirl-inducing inlet device ( 101 , 201 , 301 ) to the first separator compartment ( 112 , 212 , 312 ) and further through the pipe ( 117 , 217 , 317 ) to the second separator compartment ( 123 , 223 , 323 ); axial flow cyclones ( 107 , 207 , 307 ) arranged between the second separation compartment ( 123 , 223 , 323 ) and the separator gas outlet nozzle ( 109 , 209 , 309 ); and one or more drain pipes ( 104 , 204 , 304 ) for drainage of liquid separated from the gas in the axial flow cyclones.
