Abstract
A compressor which may also function as a vacuum pump or as a contactor has a rotor surrounded by a gill ring through which the gas or lower density fluid enters. The gas or lower density fluid, compressed if desired, is discharged from inside the gill ring.
Claims16
A compressor which comprises:
- (i) a casing,
- (ii) a rotor journalled for rotation inside the casing,
- (iii) a gill ring comprising a plurality of closely spaced stationary vanes positioned around the periphery of the rotor for directing incoming fluid to be compressed into a rotating annulus of working fluid within the gill ring for entrainment in the ring of working fluid,
- (iv) a fluid inlet communicating with the space outside the gill ring, and
- (v) a fluid outlet communicating with the space inside the gill ring.
A compressor for gases which comprises:
- (i) a casing,
- (ii) a rotor having radially-extending vanes for imparting rotational movement to a working fluid and journalled for rotation within the casing,
- (iii) a gill ring comprising a plurality of closely spaced stationary vanes positioned around the periphery of the rotor for directing incoming fluid to be compressed into a rotating annulus of working fluid within the gill ring for entrainment in the ring of working fluid;
- (iv) a fluid flow passage surrounding the outer periphery of the gill ring,
- (v) a fluid flow inlet communicating with the fluid flow passage surrounding the outer periphery of the gill ring,
- (vi) a fluid discharge outlet for compressed gas communicating with the space inside the gill ring.
In a gas compressor system which comprises a compressor, means for admitting gas to be compressed into the compressor, means for admitting a working fluid to the compressor, a liquid/gas separator connected to the discharge outlet of the compressor for separating compressed gas from liquid entrained therein, the improvement comprising a compressor having:
- (i) a casing,
- (ii) a rotor having radially-extending vanes for imparting rotational movement to a working fluid and journalled for rotation with the casing,
- (iii) a gill ring comprising a plurality of closely spaced stationary vanes positioned around the periphery of the rotor for directing incoming fluid to be compressed into a rotating annulus of working fluid within the gill ring for entrainment in the ring of working fluid,
- (iv) a fluid flow passage surrounding the outer periphery of the gill ring,
- (v) a fluid flow inlet communicating with the fluid flow passage surrounding the outer periphery of the gill ring,
- (vi) a fluid discharge outlet for compressed gas communicating with the space inside the gill ring.
A method of compressing a gas, which comprises the steps of:
- (i) passing a gas to be compressed through a gill ring comprising a plurality of closely spaced stationary vanes positioned around the periphery of a rotor,
- (ii) flowing a rotating annulus of working liquid past the inner periphery of the gill ring thereby to entrain the gas into the rotating annulus of liquid,
- (iii) separating the gas entrained in the liquid from the rotating annulus of the liquid,
- (iv) removing the separated, compressed gas from the side of the rotating annulus remote from the gill ring.
