The sprayed water exchanges heat with the gas in the compressor, so that the exhaust temperature of the compressor can be effectively reduced, and the working performance of the compressor is improved. Under the condition of a fixed water injection flow, the larger the heat exchange quantity between water and gas is, the better the performance of the compressor is. Therefore, the water spray is atomized, the diameter of the liquid drops sprayed into the water is reduced, the heat exchange area can be effectively increased, and the heat exchange quantity is increased.
