【摘要】：過去的發(fā)電廠用來傳輸煤炭的系統(tǒng)形式是半自動化,其主要方式有兩種,一種是繼電器運行,另外一種是全人工操作。而整個運輸煤炭現(xiàn)場常常處于煤塵遍布的環(huán)境下,不僅對人們的身體健康產(chǎn)生較大的危害,同時因為運輸煤炭的系統(tǒng)涉及范圍非常廣,經(jīng)常會出現(xiàn)多種故障情況,常見的情況有皮帶脫離軌道,皮帶斷開和落煤管運輸不暢等,造成發(fā)電廠工作效率始終提升不上去。而隨著社會主義經(jīng)濟迅速發(fā)展,發(fā)電廠也逐漸擴大生產(chǎn)規(guī)模,因此對煤炭的需求也大大超過以往,由此可見,過去的輸煤系統(tǒng)與發(fā)電廠經(jīng)濟日益增長的規(guī)模不相適應(yīng)。 本文對于霍煤鴻駿電力分公司1號機輸煤系統(tǒng),研發(fā)出一套能夠編程的輸煤控制操作系統(tǒng)。同時對系統(tǒng)的構(gòu)成進行了闡述,不僅分析了系統(tǒng)的軟件部分和硬件部分,同時也對人機操作界面中的通訊做了介紹,為系統(tǒng)軟件的升級打下了基礎(chǔ)。同時,本文從目前火電廠經(jīng)濟性的運行效率出發(fā)設(shè)計了一套配煤摻燒系統(tǒng)。目前,輸煤系統(tǒng)操作已經(jīng)完全進入了全自動操作領(lǐng)域,而它對于工業(yè)硬件的控制,可以產(chǎn)生相當程度的抗干擾能力,可以直接用于工業(yè)操作現(xiàn)場。雖然這樣,因為霍煤鴻駿電力分公司1號機輸煤系統(tǒng)在非常差的環(huán)境下運行,出現(xiàn)不同程序的干擾,造成輸煤系統(tǒng)無法正常完成相應(yīng)的設(shè)計和調(diào)試工作。大部分電廠的輸煤系統(tǒng)都存在兩方面原因,一方面是無法正常運行,另一方面抗干擾能力較差。本文結(jié)尾則對輸煤系統(tǒng)操作運行方面進行了深層次的探討,同時提出了若干條與抗干擾有關(guān)的建議和操作方法,在實際操作運行中有重要的參考價值。
[Abstract]:In the past, the system used to transfer coal in power plants was semi-automated. There were two main ways, one was relay operation, the other was full manual operation. And the entire coal transportation site was often in a coal dust environment. Not only does it do great harm to people's health, but also because the coal transportation system involves a very wide range, there are often a variety of malfunctions. The common conditions include belt detaching from track, belt disconnecting and coal falling pipe transportation is not smooth, and so on. With the rapid development of the socialist economy, the power plants have also gradually expanded their production scale, so the demand for coal is much higher than before. Thus, it can be seen that, The coal transportation system in the past did not match the growing scale of the power plant economy. In this paper, for the coal transportation system of No. 1 machine of Huo Coal Hongjun Electric Power Company, a set of programmable coal transportation control operating system is developed. At the same time, the composition of the system is expounded, not only the software and hardware parts of the system are analyzed, At the same time, the communication in the man-machine interface is introduced, which lays the foundation for the upgrade of the system software. At the same time, this paper designs a coal blending system based on the economical operation efficiency of the thermal power plant. The operation of coal conveying system has entered the field of fully automatic operation, and its control of industrial hardware can produce a considerable degree of anti-interference ability and can be directly used in industrial operation field. Because the coal conveying system of Huo Coal Hongjun Electric Power Branch No. 1 machine is running in a very bad environment, there is interference from different procedures. As a result, the coal conveying system is unable to complete the corresponding design and commissioning work normally. There are two reasons for the coal transportation system in most power plants. On the one hand, they are unable to operate normally. On the other hand, the anti-interference ability is poor. At the end of this paper, a deep discussion is made on the operation and operation of coal conveying system, and some suggestions and operation methods related to anti-interference are put forward. It has important reference value in practical operation.
