酸性声化学在溶除盘式热分散机硅酸盐垢中的应用
Application of Acid Phonochemistry in Removing Silicate Scale on Disk Disperser
摘要
Abstract
On the basis of traditional method of acidic cleaning, ultrasound, was jointly used to remove the silicate sacle on the disk disperser in this study. The feasibility and optimized technical parameters were also investigated. The results indicated that the self-made mixed corrosion inhibitor showed better performances than traditional corrosion mhibitor-urotropine. In contrast to the 19.70% -32.94% removal rate of silicate scale without ultrasound, 84.38% silicate scale was removed in the presence of ultrasound. For the silicate scale of 3 mm thickness, the scales were effectively dissolved when 8% - 10% acid and 200 -300 W ultrasound were applied at 40 -50℃ and cleaning fluid was 100 mL in the beaker of 150 mL. The acid phonochemical method is an effective method to remove the silicate scales on the disk disperser.关键词
