Emergency system for cooling water of air compressor during long-chain binary acid circulating water failure

The utility model provides an emergency system for cooling water of an air compressor during long-chain dicarboxylic acid circulating water failure, which comprises a chilled water return tank and the air compressor which form a closed-loop circulating system, the chilled water return tank is connected with the air compressor through a cooling circulating water inlet pipe, the air compressor is connected with the chilled water return tank through a water return pipe, and the chilled water return tank is connected with the air compressor through a water return pipe. And the chilled water return tank is also connected with a tap water pipe and a circulating water tank. According to the emergency system for cooling water of the air compressor when the long-chain dicarboxylic acid circulating water breaks down, when a circulating water system breaks down, existing equipment of a power station is used for providing cooling circulating water for the air compressor, the minimum air volume needed by strains in a ferm
