高寒地区工艺循环冷却水系统冬季运行防冻措施

Anti Freezing Measures in Winter Operation of Process Circulating Cooling Water System in Cold Area

通过对辽宁营口某生产基地工艺循环冷却水系统原设计进行分析,判断系统结冰的主要位置及原因,并采取系统优化、冷却塔布水盘改进、增设洒水导流板、添加防冻剂等防冻技术措施对原设计进行改良,并对运行管理提出了改进性建议,使系统在冬季能够正常运行。对高寒地区工业管道等工艺循环冷却水系统的防冻设计和施工及冬季运行提供参考。

This article through to the Liaoning Yingkou production base of technology of circulating cooling water system of the original design were analyzed, and the main position of judging the system freezes, and take the system optimization, cooling tower water plate, a guide plate and adding improved sprinkler add antifreeze antifreeze technical measures of original design is improved, and the operation management put forward the improvement suggestions, so that the system can run normally in winter.In this paper, we hope to provide some reference for the design and construction of the anti freezing design and construction of the technological circulating cooling water system of the industrial pipeline in cold area.
