Technical Problem
目前，现有脱硫烟气均需要先通过电除尘系统才能进入吸收塔，然而，由于烟气需要汇合进入主烟道，再由主烟道分流进入电除尘入口烟道分支，这样常常导致汇合烟气形成不稳定旋流，导致除尘器入口处形成气流偏斜，从而使得进入电除尘入口烟道分支流量分配不均；此外，汇合烟气尚来不及均流就进入电除尘入口烟道分支，使得烟气大量冲向电除尘入口烟道中间部分分支，这样电除尘入口烟道两侧部分分支烟道内烟气流量较小，从而使得烟气流速变慢，湿度较大的粉尘及金属离子混合物并逐步堆积形成结垢，堵塞烟道，导致电除尘系统无法正常运行，严重影响了除尘效率
Benefits of technology
本实用新型提供的导流系统通过设置的导流主管道、导流弯头和导流排烟管道构建完整的烟气均流路径。其中，通过设置双锥形封堵结构在变径管道内形成渐进式流道压缩，利用下锥体分散来流冲击，上锥体降低流速消除汇合烟气形成不稳定旋流，环向设置的导流件在封堵结构外周形成螺旋流道，强制烟气沿锥面旋转流动，破坏旋流并提升各通道流量均匀性；通过在弯头和导流排烟管道处设置整流格栅，实现稳流的作用，从而保证烟气更均匀地且更稳定地流向电除尘系统烟道分支。
