摘　　要：热水型溴化锂制冷机是一种应用广泛的节能型制冷设备。对热水型溴化锂制冷机组的原理、组成及特点进行了介绍,并将其应用于醋酸高温裂解气急冷过程。结果表明,在过程中引入溴化锂制冷机组后,裂解气冷却工段使用的冷却剂乙二醇的制冷量减少了405 kW,占现有用量的97.87%,节约电能83 kW,占现行能耗的30%,节能降耗效果显著。Hot-water type lithium bromide refrigerator is the equipment which has been widely used for energy-saving. In this paper, the operating principle, elements and characteristics of the lithium bromide refrigeration unit were introduced, and then it was applied to the quench cooling section of cracking gas in acetate pyrolysis process. The results indicate that it not only can reduce ethanediol consumption 405kw, but also can save electrical energy 83kw, the energy saving effect is significant.
