Problems solved by technology
Circulating water and low-temperature frozen water enter the circulating water circuit together, which increases the burden on the circulating water purification system. At the same time, a large amount of water participates in multiple cycles, which may easily lead to blockage and scaling.

The invention belongs to the technical field of air cooling, and particularly relates to a semi-open type air separation pre-cooling system. The semi-open type air separation pre-cooling system comprises an air cooling tower. The air cooling tower is internally divided into an upper space and a lower space through a partition. The top of the upper space is provided with an air outlet, and the bottom of the lower space is provided with an air inlet. The semi-open type air separation pre-cooling system further comprises a water cooling tower and a water chilling unit. The upper portion of the lower space communicates with a circulating water feeding pipe, and the lower portion of the lower space communicates with a circulating water returning pipe. The upper portion of the upper space communicates with a cooling water inlet pipe, and the lower portion of the upper space communicates with a cooling water outlet pipe. The cooling water outlet pipe communicates with the upper portion of a water cooling tower, the lower portion of the water cooling tower communicates with one end of the water chilling unit, and the other end of the water chilling unit communicates with the cooling waterinlet pipe. The semi-open type air separation pre-cooling system can guarantee independent circulation of circulating water and low-temperature cooling water, the load of a circulating water purification treatment system is reduced, and the cooling efficiency of the low-temperature cooling water is optimized.
Description
technical field [0001] The invention belongs to the technical field of air cooling, and in particular relates to a semi-open air separation precooling system. Background technique [0002] The air separation system is widely used in many engineering fields such as metallurgical engineering, and the pre-cooling system is an indispensable part of the air separation system. The temperature of the filtered and compressed air is about 100 degrees. It must be cooled by a pre-cooling system (usually including an air-cooling tower and a water-cooling tower) before entering the downstream purification system for final distillation and separation. [0003] Usually, in the process construction of the air separation pre-cooling system, the air is cooled twice by circulating water and low-temperature chilled water in the air-cooling tower. The circulating water comes from the circulating water system of the air separation plant, and the low-temperature chilled water is produced by a wat...
