1、I 水煤气洗涤塔结构及强度设计水煤气洗涤塔结构及强度设计 摘要摘要 塔设备是石油炼制，石油化工、天然气化工等生产工程不可或缺的重 要设备。塔设备的性能对于整个装置的产品产量、质量、生产能力和消耗 定额，以及三废处理和环境保护等各个方面，都有重大影响。因此，塔设 备的设计和研究，受到化工、炼油等行业的极大重视。 洗涤塔是一种新型的气体净化处理设备。它是在可浮动填料层气体净 化器的基础上改进而产生的，广泛应用于工业废气净化、除尘等方面的前 处理，净化效果很好。对煤气化工艺来说，煤气洗涤不可避免，无论什么 煤气化技术都用到这一单元操作。由于其工作原理类似洗涤过程，故名洗 涤塔。洗涤塔与精馏塔类似。本

2、设备用于煤气化工段，用于净化和冷却粗 煤气。本文主要介绍了洗涤塔的设计，着重叙述了塔设备结构的确定、材 料的选择、强度的计算、地震载荷以及卡曼涡街的计算等。 该洗涤塔分为气液接触区、洗涤区和气固，气液分离区。粗煤气从洗涤 塔中部进入洗涤塔，与激冷水接触混合，对粗煤气进行洗涤和净化。煤气继续 向上进入泡罩塔板，用冷凝液进行再次洗涤，气体进一步净化。经过塔板洗涤 后的煤气上升至旋流板除沫器，分离灰分和液态水。 关键词关键词: : 结构设计、强度校核、卡门涡街 II Water gas washing tower structure and the strength design Abstract

3、The tower equipment is an important oil refining, petrochemical, gas and chemical production engineering equipment. Tower equipment performance for the entire device product yield, quality, production capacity and consumption quotas, as well as all aspects of waste treatment and environmental protec

4、tion have a significant impact. Therefore, the design of the tower equipment and research, by the great weight of the chemical, oil refining and other industries The scrubber is a new type of gas purification equipment. Floating filler layer gas purifier on the basis of improvement produced by widel

5、y used in the pre-treatment of industrial waste gas purification, dust and other aspects of the purification works well. For coal gasification process, gas washing is inevitable, no matter what the gasification technology used in this unit operation. Due to its working principle is similar to the wa

6、shing process, hence the name scrubber. Scrubber similar to the distillation column. The equipment used for gas chemical industry segment for the purification and cooling of the crude gas. In this paper, the design of the scrubber, focusing on narrative structure of the tower equipment, material selection, calculation of the intensity, seismic load and Kaman Vortex calculation The scrubber is divided into the gas-liquid contact area, washing area and the gas-solid, gas-liquid separation zone.
