文章针对高温高压的条件对传统旋风分离器入口结构进行改进,提出了圆柱形径向插入、端面加导流板结构的新型旋风分离器结构。由冷态模型下对超细滑石粉和FCC催化剂颗粒的分离效率-压降对比试验结果表明,新型旋风分离器入口结构强度性能优良,虽然对超细粉料分离性能略有不足,但对大颗粒粉料的分离性能接近传统直切入口旋风分离器,可以满足要求。并且数值流场模拟结果表明,分离器压降与实验结果相一致。
In this paper, the inlet structure of traditional cyclone is improved according to the conditions of high temperature and high pressure. A new cyclone structure with cylindrical radial insertion and end face plus baffle structure is proposed. The experimental results of the separation efficiency-pressure drop comparison of the ultrafine talc and FCC catalyst particles under the cold model show that the inlet strength of the new cyclone separator is excellent. Although the separation performance of the ultrafine powder material is slightly inadequate, Particle powder separation performance close to the traditional straight-cut inlet cyclone, to meet the requirements. And numerical simulation of flow field shows that the pressure drop of the separator is consistent with the experimental results.
