摘　　要：针对MOX燃料(钚铀氧化物混合燃料)芯块磨削生产线粉尘吸收问题,结合国内外现有的除尘技术及MOX燃料芯块粉尘的性质,设计了一种基于过滤除尘技术,应用扰流板、反吹原理进行三级过滤的脉冲反吹工业集尘器,使磨削产生的0.3 μm粒度以上的粉尘的吸收率达到99%,无二次污染。并将该集尘器应用于模拟MOX燃料芯块磨削试验研究中,与管道系统,风机及控制测试辅助装置等设计出一套除尘方案,经验证效果明显,证明了该集尘器的有效性,该设计方案的可行性。Aiming at the dust absorption problem of MOX fuel pellet grinding line, combined with the existing dust removal technology and the nature of MOX fuel pellet dust, this paper designs a filter named pulse backflush industrial dust collector, based on filter dust removal technology, using spoiler, and anti-blowing principle to filter for three times, which makes the dust particles above 0.3 μm be ab-sorbed by 99%, without secondary pollution. The dust collector is applied to the MOX fuel pellet grinding test, and a dust removal scheme is designed with the pipeline system, the fan and the con-trol test AIDS. The effect is obvious, thus the effectiveness of the dust collector and the feasibility of the design system are proved.
