文档介绍：电解铝烟气净化集散控制系统
摘要
随着工业的发展,现代化、信息化进程的加快,新时代的工业对工业尾气排放日趋重视,一旦废气处理不当直接排放会对环境以及人民生命财产带来重大影响。因此必须妥善处理废气,达标排放。
本设计就是针对电解铝烟气排放做的一个回收净化的控制,介绍了集散控制系统以及其控制过程。附带介绍集散控制系统各部分的功能和设备要求。
本设计详细介绍了电解铝烟气从出来到进入布袋除尘器处理,再到排放一系列的控制过程。对实现控制目标的每一个设备的选型,以及设备组态软件做了详细叙述。
在本论文的最后写了集散控制系统的前景展望,以及工业控制未来的发展,和世界一些关于工业废气处理的先进技术。

Abstract
With industrial development, modernization and information technology to speed up the process, new era of industrial to industrial emissions increasing attention, Once the exhaust emissions of impropriety directly on the environment and people's lives and property have significant ramifications. It is necessary to properly handle exhaust emission standards.
The smelter was aimed at the design of flue gas emissions do a recovery and purification of control, on the distributed control system and its control processes. With distributed control system on the part of the functional and equipment requirements.
This smelter details the smelter out of the smoke from entering the bag filter, and then a series of emission control process. To achieve the control objectives for each of a selection of equipment, and equipment configuration software gave a detailed description.
In this paper the final was made to the Distributed Control System Prospect, and industrial control future development, and some of the world's industrial emissions of advanced technology.
Keywords:Electrolytic aluminium; Haze purification technology; Distribution control system
