化工装置空冷和水冷应用对比和选择

COMPARISON AND SELECTION OF COOLING BY WATER AND AIR APPLIED IN CHEMICAL PLANTS

分析说明水冷、各种空冷的型式和应用特点,对水冷、直接空冷、间接空冷大规模应用于乏汽冷却进行技术经济性对比,提出在不同水资源条件下大规模冷却选择的方式,并指出在化工装置中的工艺余热冷却中,空冷有巨大的应用潜力。

Characteristics and types of water cooling and air cooling have been analyzed and described.Technical economy of exhaust steam cooling applied largely with water cooling, and direct air cooling and indirect air cooling has been compared. At last, an appropriate way of large scale cooling under different water resource conditions has been put forward, and a huge potential of air cooling has been pointed out in waste heat cooling application.
