DN700旋流板塔设计 摘要 设计一旋流板塔，用于净化废气中的粉尘，任务书给定了塔高，塔径等相关参数。 因为对化工类塔设备认识比较少，在老师的帮助下，找了几本老师指定的书，深入了解了化工方面的许多知识，弄懂了旋流板塔的工作原理，初步确定了设计思路与设计方向。 通过对旋流板塔给定设计条件进行分析，预定好设计方法和步骤。在对旋流板塔的塔体、内件、支座及附件部件的材料选择时，不仅要满足工艺设计，还要考虑自然因素，来进行壁厚计算和强度校核。对加工工艺、装配程序和安全防腐的要求，以及在制造、运输与安装时的注意事项。绘制符合设计要求的旋流板塔图纸，并给出技术要求。 在旋流板塔的结构设计过程中，要以设计书为标准进行规范设计，使设计符合相关标准，同时要满足生产的需求和符合安全生产要求。 关键词：旋流板塔；压力损失；除尘效率；强度； ABSTRACT A swirli
