一种海水直流冷却系统高效复合型消泡剂
摘要
滨海发电厂利用海水作为冷却用水时
直流冷却系统存在泡沫严重问题。对此
通过优化配方及乳化工艺
研制出一种专用消泡剂。研究结果表明
当硅膏∶聚醚改性聚硅氧烷质量比为9∶1
乳化剂HLB值为9.5
乳化剂用量为5%
乳化温度70℃时
制备出的消泡剂性能最佳。投加固含量
40%的消泡剂
28mg/L消泡及抑泡率即可达到100%
性能明显优于其他同类消泡剂
可有效解决海水直流冷却系统的泡沫问题。
Abstract
Aiming at the serious foaming problems existing in cooling system when using seawater as the cooling water in power plants
an effective defoamer was developed to inhibit the foaming.The recipe optimization shows that when the mass ratio of silicon cream to polyether-polysiloxane is 9to 1
the HLB value of emulsifier is 9.5
the mass fraction of the emulsifier is 5% and the emulsification temperature is 70 ℃
the defoamer prepared performs the best.At the addition of 28mg/L
the defoaming rate of 40% defoamer liquid can reach 100%
proving that the prepared defoamer can solve the foaming problems effectively.
