Abstract

The application provides a compressor air intake cooling system and compressed air energy storage system, and belongs to the technical field of compressed air energy storage. The compressor air intake cooling system comprises a compressor, a double-fluid nozzle integrated component, a gas supply path and a liquid supply path. The compressor has an air inlet and an air outlet. The double-fluid nozzle integrated component is installed on the air inlet, and the outlet of the double-fluid nozzle integrated component is communicated with the air inlet. One end of the gas supply path is connected with the gas channel of the double-fluid nozzle integrated component, and the other end is connected with the air outlet. One end of the liquid supply path is connected with the liquid channel of the double-fluid nozzle integrated component, and the other end is connected with a cooling liquid storage device. The double-fluid nozzle integrated component is used to provide a lower pressure without high temperature, so that a high gas-liquid flow rate difference can be realized, liquid fine atomization can be realized, the lower pressure can effectively reduce the nozzle wear rate, the maintainability can be improved, the installation requirements of the pipeline and equipment can be reduced, and the reliability and safety of the system can be improved.
