摘要
在传统酸洗除去热分散机齿盘硅酸盐垢的基础上,增加超声波,探索声化学法溶除盘式热分散机硅酸盐垢的可行性及较佳技术参数。结果表明:与常规的盐酸缓蚀剂乌洛托品相比,自配混合缓蚀剂有更好的缓蚀效果;无超声波时,溶液的溶垢率在19.70%～32.94%,加超声波后,溶液的溶垢率最高可达84.38%。当硅酸盐垢物厚度为3 mm左右时,较佳清洗参数为:150 mL烧杯加100 mL清洗液,清洗温度40～50℃,溶液HCl质量分数8%～10%,超声波功率200～300 W。超声波配合低浓混酸溶液的声化学方法,能够快速、安全、清洁、有效地溶解热分散机盘片上的硅酸盐垢,降低清洗液对设备的腐蚀。
On the basis of traditional method of acidic cleaning, uhrasound, 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 inhibitor-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 phonoehemical method is an effective method to remove the silicate scales on the disk disperser.
