Large air cooling tower for air separation

The invention relates to the field of air separation, in particular to a large air cooling tower for air separation. The invention provides a large-scale air cooling tower for air separation, which can rotatably spray cooling water, enlarge the spraying range of the cooling water and ensure complete cooling and separation of air. A large air cooling tower for air separation comprises an outer box, a top cover, side frames, an inlet pipe, an exhaust mechanism and the like, the top cover is connected to the upper side of the outer box, the side frames are connected to the inner side of the middle of the outer box, the inlet pipe is connected to the lower portion of the outer box, and the exhaust mechanism capable of exhausting cooled air is arranged on the top cover. When the rotating shaft rotates, the lifting ring is driven to rotate, the rotating sleeve drives the rotating pool to rotate, the water distributor rotates, cooling water flows out of the fixed pool and then is introduced into the water distributo
