Abstract

The objective of the present invention is to provide a liquid feed system for a compressor, capable of easily forming fine droplets of a liquid to be injected into the compressor. A liquid feed system 100 of a compressor 1 for compressing a gas injects a liquid 50 into the inside of the compressor 1. The liquid feed system 100 adjusts the temperature of the liquid 50 to be injected into the compressor 1 to a temperature at least equal to a saturation temperature Tf corresponding to a pressure inside the compressor 1, and adjusts the temperature to a temperature lower than a saturation temperature Ti corresponding to a pressure of the liquid 50 at the time of injection into the compressor 1, and then injects the liquid 50 into the compressor 1.

Claims7

Dependent claims

A liquid feeding system for injecting liquid into a compressor that compresses a gas, the liquid feeding system including:

a pump configured to pressurize a pressure of the liquid;
a first flow path through which the liquid pressurized by the pump flows;
a second flow path through which the liquid discharged from the compressor flows, the liquid having a temperature higher than a temperature of the liquid flowing through the first flow path;
a mixer configured to mix the liquid flowing through the first flow path with the liquid flowing through the second flow path;
a third flow path configured to inject the liquid mixed by the mixer into the compressor;
and
a flow rate adjusting valve configured to adjust a temperature of the liquid flowing through the third flow path by adjusting a flow rate of the liquid flowing through the first flow path or the second flow path,
wherein a temperature of the liquid injected into the compressor is adjusted to a temperature equal to or higher than a saturation temperature corresponding to a pressure inside the compressor, and the liquid is injected into the compressor.
