The air cooling tower is the core equipment of the air separation precooling system, which is mainly used to cool and wash the high-temperature compressed air discharged from the air compressor, provide qualified low-temperature gas source for subsequent molecular sieve purification and cold box rectification, and ensure the stable operation of the whole unit.
The air cooling tower adopts the countercurrent packing heat exchange structure, the tower is filled with high-efficiency packing, and the top is equipped with a spray device and a wire mesh demister. During operation, the high-temperature compressed air at 80 to 100 ℃ discharged by the air compressor enters from the bottom of the tower and flows from bottom to top; The cooling water is the normal temperature make-up water and the low-temperature chilled water prepared by the water-cooling tower, which is sprayed from top to bottom from the tower top, and the air and water are fully contacted in reverse for heat exchange.
