摘　　要：颗粒床除尘器因其耐高温、耐腐蚀、运行阻力低、除尘效率高等优点,受到了越来越广泛的关注,也使其成为最具发展前途的除尘技术之一.文章优化了工业尺寸移动床除尘器入口结构,通过加入导流板的形式消除气流不均匀分布对除尘性能的影响,优化结果表明:加入9个导流板时能最大限度保证入口气流均匀性,使进入颗粒床主体的气流速度差降到了0.8m/s以下,并且导流板尾部的弧形设计对均匀性起了决定性作用.Due to its advantages of high temperature resistance,corrosion resistance,low running resistance and high dust removal efficiency,the granular bed precipitator has attracted more and more attention and made it one of the most promising dust removal technologies.In this paper,the inlet structure of industrial-sized mobile granular bed precipitator is optimized.The effect of non-uniform airflow distribution on the dust removal performance is eliminated by adding aguide plate.The optimization results show that the inlet airflow uniformity can be maximized when 9 baffles are added.The velocity difference of the gas flow into the main body of the granular bed is reduced below 0.8 m/s,and the arc design of the tail of the baffle fin plays a decisive role on the uniformity.
