摘    要
 冶金工業(yè)是耗能大戶，在一些冶金設(shè)備中隨著排放的廢氣帶走了大量的余熱，同時也排放出大量的粉塵，因而既浪費了能源，又污染了環(huán)境。因此，回收利用燒結(jié)礦冷卻廢氣余熱是節(jié)能降耗，保護環(huán)保的重要舉措，所以很有推廣意義。本次設(shè)計主要介紹了基于Quantum系列PLC的燒結(jié)余熱回收裝置的控制系統(tǒng)，本系統(tǒng)主要涉及組態(tài)軟件、PLC系統(tǒng)、儀表、電氣等方面的知識。在這次設(shè)計中，介紹了利用燒結(jié)機冷卻廢氣余熱生產(chǎn)蒸汽的工作原理、設(shè)備流程、自動控制以及生產(chǎn)效果、并預(yù)測投運后的使用效果及其經(jīng)濟效益。上位機采用了MCGS組態(tài)軟件搭建計算機控制界面，下位機采用Quantum系列PLC自動化平臺控制，結(jié)合了電氣及檢測技術(shù)完成對水的加熱及蒸汽的輸送，用過熱蒸汽回收余熱。MCGS是由北京昆侖通態(tài)自動化軟件公司開發(fā)的一整套基于Windows平臺的、用于快速構(gòu)造和生成上位機監(jiān)控系統(tǒng)的組態(tài)軟件系統(tǒng)。Quantum是施耐德電氣公司推出的世界上第一個通用自動化平臺，具有強大處理能力的大型控制系統(tǒng)。

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.
