一种SCR烟气脱硝装置

Abstract

本实用新型公开了一种SCR烟气脱硝装置，涉及烟气脱硝技术领域，包括塔体，所述塔体的顶部设置有布袋器，所述布袋器的顶部设置有进烟口，所述塔体的顶部设置有进气口，烟气经进烟口进入布袋器，通过布袋过滤去除颗粒物，洁净烟气向下进入塔体，氨气通过进气口进入盘管，经盘管底部喷嘴均匀喷出，与烟气混合，所述塔体的内部设置有连接架，所述连接架的底部固定连接有盘管，通过连接架带动盘管的动态高度调节，使氨气喷射范围覆盖塔体内不同高度的烟气层，避免传统固定喷射导致的氨气分布不均问题，且固定杆与环形孔的斜向限位作用，将轴向位移转化为周向旋转，使盘管在喷射氨气时同步进行旋转，旋转运动突破径向扩散局限，显著提升氨气分布均匀性。
