我国火电厂循环冷却水处理技术的发展

DEVELOPMENT OF RECIRCULATING COOLING WATER TREATMENT TECHNIQUES IN THERMAL POWER PLANTS OF OUR COUNTRY

介绍电力体制改革后我国火电厂循环冷却水处理技术面临的主要问题和今后的发展方向。根据目前的实际需要和可能 ,认为近期内各火电厂循环水的浓缩倍率应以大于 3为控制目标 ,为此提出了 8点建议 :(1 )完善循环水的外部处理方法 ;(2 )开发新型水质稳定剂和高效复合配方 ;(3)加强凝汽器管防腐技术研究 ;(4 )对城市污水用于循环水技术进行研究 ;(5 )探索其它杀菌剂的应用 ;(6 )加强自动控制技术的应用 ;(7)对运行中除垢技术进行研究 ;(8)循环水处理药剂应定点生产。

The main problems lying ahead of recirulating cooling water treatment techniques in thermal power plants of our country after reform of the power system and the development direction of said techniques in the future have been presented. Based on the practical demand and possibility at present, it is considered that the enrichment factor of circulatory water at each thermal power plant in the near future should be greater than three, and taking this factor as a control target. For this reason, eight points of recommendation have been put forward as follows: (1) perfection of external treatment method for circulatory water; (2) development of new stabilizing agents and high-effective complex prescription; (3) strengthening the research of anticorrosion technology for condenser tubes; (4) carrying out the study on technique of using urban sewage as recirculating water; (5) exploring application of other pestisides; (6) strengthening application of automatic control techniques; (7) carrying out the study of descaling technique during the time of operation; (8) assigning fixed points to produce agents used for circulatory water treatment.
