摘    要
 冶金工业是耗能大户，在一些冶金设备中随着排放的废气带走了大量的余热，同时也排放出大量的粉尘，因而既浪费了能源，又污染了环境。因此，回收利用烧结矿冷却废气余热是节能降耗，保护环保的重要举措，所以很有推广意义。本次设计主要介绍了基于Quantum系列PLC的烧结余热回收装置的控制系统，本系统主要涉及组态软件、PLC系统、仪表、电气等方面的知识。在这次设计中，介绍了利用烧结机冷却废气余热生产蒸汽的工作原理、设备流程、自动控制以及生产效果、并预测投运后的使用效果及其经济效益。上位机采用了MCGS组态软件搭建计算机控制界面，下位机采用Quantum系列PLC自动化平台控制，结合了电气及检测技术完成对水的加热及蒸汽的输送，用过热蒸汽回收余热。MCGS是由北京昆仑通态自动化软件公司开发的一整套基于Windows平台的、用于快速构造和生成上位机监控系统的组态软件系统。Quantum是施耐德电气公司推出的世界上第一个通用自动化平台，具有强大处理能力的大型控制系统。

The design of the agglomerate waste heat recovery system base on the Quantum PLC
Abstract
 Metallurgy industry is a trade whose energy consumption is very great. A great quantity of residual heat is taken away with discharged waste gas in some metallurgy equipment, and at the same time a great quantity dust is discharged. Therefore not only a great deal energy sources are wasted, but also the environment is polluted. Therefore, the recycling using of the agglomerate of cooling waste gas afterheat is the important action of environmental protection and energy conservation consumes falling. So the system is worthy of generalizing. This design mainly introduced that the control system which based on Quantum the series PLC agglutination afterheat recycling installment. This system mainly contains PLC system, measuring appliance， electricity knowledge configuration software, and so on. In this design, the principle, flow sheet, automatic control and application result s of the production of steam from waste heat in waste gases out of sintering circular - cooler are discussed，and forecast the using effect and the economic efficiency after running. The position machine used the MCGS configuration software to build computer control interface, the lower position machine was controlled by the Quantum series PLC automation platform. Fixed electrical and the examination technology to completes the heating of water and the steam transportation， water was used to recover afterheat of vapor’s superheat. The MCGS software based on the Windows platform, which is set by the Beijing Kunlun Mountains that develops the automated software company, was used to structure the production and build machinery supervisory system of the configuration software system fast. Quantum is the first general automated platform which Schneider Electricity Company promotes in the world. It has large-scale handling ability on control system.
