大气污染控制工程课程设计厦门理工学院环境工程系2015年1月某厂酸洗硫酸烟雾治理设施设计The Facility Design of X Company for Pickling Sulphuric Acid Gas Governance[摘要]大气污染已经成为了一个全球性的问题，大气污染已经直接影响到人们的身体健康，所以必须通过有效的措施进行治理，大气污染控制工程课程设计是配合大气污染控制工程专业课程而单独设立的设计性实践课程。

本次设计是对某厂酸洗硫酸烟雾治理设施进行设计。

其主要内容包括：集气罩的设计、填料塔的设计、管网的布置及阻力计算等。

本设计采用液体吸收法进行净化，即采用5%NaOH溶液在填料塔中吸收净化硫酸烟雾，经过净化后的气体达到大气污染物综合排放标准。

本次设计通过对酸洗硫酸烟雾治理净化，使我们能够初步掌握治理净化系统设计的基本方法，以及综合分析问题和解决实际问题的能力。

[Abstract]Atomsphere pollection has become a global issue.And efficient measures are urgengtly needed to govern the air pollution,as the air pollution has caused the direct impact on human health. Curriculum Design of Air Pollution Covernace is an experiment-designing course which is set up to assist the course of Air pollution control engineering.This design is aim to devise the treatment facility on pickling sulphuricacid for x factery , which includes the design of gas- ullecting hood and packed tower,the layout of prpe network ,and the calculation of resistance and soon.This design is on the basis of the purification by uguid absorption -stripping,that is the using of 5% liquor NaOH is packed tower to absorb andpurity sulphuric acid.After purification,the air reaches air pollutant release standards.[关键词]硫化工艺；脱硫；碱液吸收法；SDG法[Key words] Vulcanization process；Desulphurization；Alkali absorption method；SDG目录前言................................................................................................................................................... - 4 -一、设计概述..................................................................................................................................... - 5 -1.1设计目的...................................................................................................................................... - 5 -1.2设计要求及任务 .......................................................................................................................... - 6 -1.3设计任务分工 .............................................................................................................................. - 6 -二、设计内容..................................................................................................................................... - 7 -2.1设计任务书.............................................................................................................................. - 7 -2.1.1 课程名称........................................................................................................................... - 7 -2.1.2 基础资料........................................................................................................................... - 7 -2.2工艺原理.................................................................................................................................. - 9 -2.3设计方案的比较和确定 .......................................................................................................... - 9 -2.3.1 除雾器 ........................................................................................................................... - 10 -2.3.2 SDG法 ............................................................................................................................ - 11 -2.3.3液体吸收法 .................................................................................................................... - 12 -2.4. 处理单元的设计计算 ......................................................................................................... - 12 -2.4.1 集气罩的设计计算 ....................................................................................................... - 12 -2.4.2集气罩入风口的计算 .................................................................................................... - 14 -2.4.3填料塔的设计 ................................................................................................................ - 15 -2.4.4填料塔有关附件的选择 ................................................................................................ - 22 -2.4.5加料搅拌池和储液池的设计计算 ................................................................................ - 24 -2.4.6储液池的设计计算 ........................................................................................................ - 24 -2.4.7水泵的选取 .................................................................................................................... - 25 -2.4.8管网的设计及系统阻力计算 ........................................................................................ - 26 -2.4.9系统阻力计算 ................................................................................................................ - 29 -2.4.10节点压力平衡计算 ...................................................................................................... - 32 -2.4.11总压力损失 .................................................................................................................. - 33 -2.4.12烟囱设计高度 .............................................................................................................. - 34 -2.5工艺流程图、设备图 ............................................................................................................ - 38 -三、总结........................................................................................................................................... - 38 -四、参考文献................................................................................................................................... - 39 -五、附录........................................................................................................................................... - 40 -前言我国的能源结构以煤为主，是世界上最大的煤炭生产国和消费国。
