摘　　要：针对SDB28-14型湿式电除尘器除尘效果差的问题,分析认为是喷嘴口易堵塞且结构配置不合理、喷水压力未达到最佳值造成的。采取更换喷射角为60°的实心喷嘴、将水压提升至0.350 MPa等措施后,湿式电除尘器除尘率由87.0%提高到98.6%,检修周期由6个月/次提高到12个月/次,每年节省23.23万元。In view of the poor dust removal effect by the SDB28-14 wet electrostatic precipitator,this was caused by such factors as nozzles being apt to be blocked,structure arrangement being unreasonable and spray hydraulic pressure not reaching to the optimal value according to analytical results.After taking these measures such as substituting solid nozzles with a injection angle of 60°for old ones and increasing the water pressure to 0.350 MPa,the dust removal rate by the wet electrostatic precipitator was increased to 98.6%from 87.0%,the maintenance cycle was increased to 12 months per time from 6 months per time,and then 232.3 thousand Yuan was saved per year.
