设计简介
[摘要] 旋风除尘器由进口管、筒体、锥体、排气管、灰斗几部分组成，旋风除尘器是利用气流旋转过程产生的离心力，使粉尘从含尘气流中分离出来的。气流做旋转运动时，粉尘在离心力的作用下甩向外壁，到达外壁的粉尘在下旋气流和重力的共同作用下沿壁面落入灰斗。本设计主要介绍了旋风除尘器各部分结构尺寸的确定以及旋风除尘器性能的计算。以普通旋风除尘器设计为基础，结合现代此类相关课题的研究方法，设计出符合一定压力损失和除尘效率要求的除尘器，在CAD/CAM软件辅助设计的基础上，绘制旋风除尘器装配图、零件图。本设计分以下几部分对以上内容进行了讨论：首先，通过查阅资料计算出旋风除尘器各部分尺寸；其次，绘制出旋风除尘器装配图及旋风除尘器各零部件图；最后，整理资料，选取与论文相关的英文文献进行翻译并完成设计说明书。

[Abstract] Cyclone dust collector comprises an inlet pipe, cylinder, cone, an exhaust pipe, an a few parts, cyclone dust collector is the centrifugal force generated by the airflow rotation process, the dust is separated from the gas stream. Air rotating movement, the role of dust under the centrifugal force thrown to the wall to wall, the dust in air and under action of gravity along the wall into ash hopper. This paper introduces the design calculation of cyclone dust collector to determine the size and structure of each part of the cyclone dust collector performance. To the ordinary cyclone design as the foundation, combining the research methods of modern such issues, designed in line with certain pressure loss and the dust removal efficiency requirements of the precipitator, based on CAD/CAM software aided design, drawing the cyclone assembly diagram, parts diagram. This design is divided into the following parts of the above contents are discussed: firstly, through access to information to calculate the size of each part of the cyclone dust collector; secondly, draw the cyclone dust collector cyclone assembly drawing and parts drawing; finally, data sorting, selection and the related English literature translation and complete the design specification.
