一种脱硫塔静电除尘器

Abstract

本实用新型公开了一种脱硫塔静电除尘器，涉及脱硫塔除尘器技术领域，包括除尘器壳体，所述除尘器壳体的内部设置有湿式静电除尘组件，所述除尘器壳体的顶部设置有驱动组件；所述湿式静电除尘组件包括固定连接在除尘器壳体内壁的若干个支撑杆。本实用新型实现高效除尘与净化，提升烟气处理效果：湿式静电与喷淋协同，湿式静电除尘盘可通过静电吸附烟气中的颗粒物，而上、下喷淋管分别位于其上下两侧，喷淋头能向除尘盘及周围喷洒液体(如脱硫剂)，一方面增强对颗粒物的吸附与沉降，另一方面可中和烟气中的酸性成分，配合除沫器去除烟气中夹带的液滴，实现“静电吸附+喷淋净化+除沫”的多级处理，大幅提升烟气净化效率。
