Abstract
A positive displacement rotary compressor is designed for near isothermal compression, high pressure ratios, high revolutions per minute, high efficiency, mixed gas/liquid compression, a low temperature increase, a low outlet temperature, and/or a high outlet pressure. Liquid injectors provide cooling liquid that cools the working fluid and improves the efficiency of the compressor. A gate moves within the compression chamber to either make contact with or be proximate to the rotor as it turns.
Claims23
A method for compressing a fluid using a compressor, the compressor comprising:
- a cylindrical rotor casing, the rotor casing having an inlet port, an outlet port, and an inner wall defining a rotor casing volume;
- a rotor;
- a drive shaft, wherein the rotor is rigidly mounted to the drive shaft for rotating with the drive shaft relative to the cylindrical rotor casing;
- and
- at least one liquid injector connected with the rotor casing to inject liquid into the rotor casing volume,
- the method comprising, sequentially:
- receiving a fluid into the rotor casing volume through the inlet port;
- rotating the rotor to compress fluid in the rotor casing volume;
- injecting cooling liquid into the rotor casing via the at least one liquid injector;
- and
- expelling liquid and compressed gas out of the outlet port.
A positive displacement compressor, comprising;
- a cylindrical rotor casing, the rotor casing having an inlet port, an outlet port, and an inner wall defining a rotor casing volume;
- a rotor;
- a drive shaft, wherein the rotor is rigidly mounted to the drive shaft for rotation with the drive shaft relative to the cylindrical rotor casing;
- and
- at least one liquid injector connected with the rotor casing to inject liquid into the rotor casing volume,
- wherein the inlet port is configured to enable suction in of a fluid, and the outlet is configured to enable expulsion of both liquid and gas.
