一种燃煤可吸入颗粒物及重金属联合脱除的远程监控系统 A remote monitoring system of coal-fired respirable particulate matter and heavy metals combined with removal

技术领域 Technical Field

[0001] 本发明涉及燃煤烟气净化智能监控领域,特别是涉及一种燃煤可吸入颗粒物及重金属联合脱除的远程监控系统。 [0001] The present invention relates to a coal-fired flue gas purification intelligent monitoring field, in particular, to a remote monitoring system of coal-fired respirable particulate matter and heavy metals in the United removal.

背景技术 Background

[0002] 重金属汞作为一种非常重要的全球性污染物而备受关注,即使是在浓度非常低的情况下,它对人类和野生动植物都有相当大的毒性,大气环境中汞的来源除一部分来自天然排放外(例如火山活动和矿藏释放)外,很大一部分来自人为活动,其中煤燃烧所释放的汞就占有较大的比例(30%以上)。 [0002] The heavy metal mercury is a very important global pollutants of concern, even at very low concentration case, its human and wildlife has considerable toxicity, atmospheric sources of mercury in the environment in addition to part from natural emissions outside (such as volcanic activity and mineral release), the large part from human activities, including mercury released from burning coal would account for a large proportion (over 30%). 由于我国煤炭占能源结构比例比较大,所以燃煤烟气中除了燃煤可吸入颗粒物外,汞污染问题更加突出,对人类健康和环境有明显危害,汞及其化合物可通过呼吸道、皮肤和消化道等不同途径侵入人体,造成神经性中毒和深部组织病变, 而且汞毒性具有积累性,往往需几年或者十几年才有所表现,所以在科学实验和工程实践对可吸入颗粒物及汞的脱除过程中,应尽量避免与脱除设备的近距离接触,使操作、监控系统与烟气治理设备在空间上进行分离。 Because the proportion of the energy structure of coal is relatively large, so in addition to flue gas of coal-fired respirable particulate matter, the mercury pollution problem is more prominent, on human health and the environment have obvious hazards of mercury and its compounds through the respiratory tract, skin and digestive Road, and other various channels into the human body, causing nerve poisoning and deep tissue lesions, and toxicity of mercury are cumulative, often takes years or ten years have demonstrated, so the scientific experiments and engineering practice of respirable particulate matter and mercury removal process, should try to avoid close contact with the removal of the device, the operator, monitoring system and flue gas treatment devices are spatially separated. 这就需要自动监控体系和远距离的信号传输体系, 使操作员在远距离进行数据监控和数据分享,减少与有毒有害物质的近距离接触,并且便于数据的收集和整理。 This requires automatic monitoring system and long-distance signal transmission system, the operator in the remote data monitoring and data sharing, reducing close contact with hazardous substances, and facilitate the collection and collation of data.

[0003] LabVIEff是目前唯一的编译型图形化编程语言,以计算机作为仪器的硬件支撑,充分利用计算机的运算、存储、调用、显示及文件管理等功能,把传统仪器的专业化功能软件化,使之与计算机融为一体,这样便构成了一台从外观到功能都与传统仪器完全相同,同时又充分享用了计算机资源的仪器系统。 [0003] LabVIEff is the only compiler-based graphical programming language, computer hardware support as an instrument, make full use of computer processing, storage, recall, display and file management functions, the traditional instruments of the specialized functions of the software, make it blend with the computer, so they constitute one from the appearance of features are identical to the traditional instruments, while fully enjoying the instrument system computer resources. 传统仪器通常由信号采集、信号分析和信号输出三部分组成。 Traditional instruments usually consists of signal acquisition, signal analysis and signal output of three parts. 虚拟仪器同样可以划分为数据采集、数据分析处理和结果显示三大功能模块。 Virtual instrument can also be divided into data acquisition, data analysis and the results show three functional modules. 虚拟仪器系统是由计算机、硬件平台和应用软件组成的。 Virtual instrument is a computer system, hardware platform and application software components. 从构成方式,则有以数据采集卡(DAQ)和信号调理电路组成的PC-DAQ测试系统,以GPIB、VXI、串行总线和现场总线等标准总线仪器为硬件组成的GPIB系统、VXI系统、串行总线系统、现场总线系统等。 From the approach that there are PC-DAQ test system data acquisition card (DAQ) and signal conditioning circuit to GPIB, VXI, serial bus and field bus standard equipment for the GPIB bus system consisting of hardware, VXI system, serial bus system, fieldbus systems. 目前通常采用的方法是在计算机上插入数据采集卡,用软件进行信号分析处理并在计算机屏幕上生成仪器面板。 The current commonly used method is to insert the data acquisition card in the computer, using the software for signal analysis and generation instrument panel on the computer screen.

[0004] 虚拟仪器在国外的应用相当普及,例如美国大学的机械系和电子系,凡是涉及到测试和控制的工作都在使用LabVIEW进行编程。 [0004] Virtual Instrument quite popular in foreign countries, such as mechanical engineering department and electronic department of the American University, all related to the testing and control work in the use of LabVIEW programming. 虚拟仪器已在超大规模集成电路测试,现代家用电器测试以及军事、航天、工厂测试等领域得到广泛应用。 Virtual instrument has been widely used in VLSI test, test household appliances and modern military, aerospace, factory testing, and other fields.

[0005] 由于诸多原因,虚拟仪器进入我国的时间较晚,从事虚拟仪器研究和开发的科研单位数量也很少,对于实验室自动控制的概念相对落后。 [0005] For many reasons, the virtual instrument into China late, the number of research institutions engaged in research and development of virtual instrument rarely, for laboratory automation concept is relatively backward. 尤其对大型电站燃煤烟气中的可吸入颗粒物及重金属汞的远程监测,更缺乏一种行之有效的智能监控方法。 Especially for large-scale coal-fired power plant flue gas particulate matter and heavy metals like mercury of remote monitoring, but the lack of an effective method for intelligent monitoring.

[0041 ] 数据存储模块为了使采集的数据可以在以后调用,就需要把测试数据永久的保存在计算机内。 [0041] The data storage module in order to make the data collected can be called in the future, we need to permanently save the test data in the computer. 这里LABVIEW提供文件I/O功能,文件I/O VI和函数用于打开和关闭文件, 读写文件,在路径控件中创建指定的目录和文件,获取目录信息,将字符串、数字、数组和簇写入文件。 Here LABVIEW provides file I / O functions, file I / O VI and functions for opening and closing files, reading and writing files, create directories and files in the specified path control, get directory information, the strings, numbers, arrays, and clusters written to the file. 保存好的文件可以采用.txt和.exerl文件打开,进行数据处理。 You can use the saved file and .exerl .txt file is opened for data processing.

[0042] 通过对上述各模块的整合与调整,最终完成系统。 [0042] By the above module integration and adjustment, the final completion of the system. 系统运行时,计算机界面可实时显示系统中设置热电偶与流量计所测量的温度值与流量。 The system is running, the computer interface can be real-time display system settings and thermocouple temperature and flow meter measured. 显示界面还可以显示各个热电偶与流量计所测量数据的波形图。 Display screen can also display various thermocouple flowmeter waveform data measurements. 如果需要对所测量的数据进行处理,可随时对界面进行修改添加。 If you need to process the measured data can be added at any time to modify the interface.

[0043] 由于测试系统是基于CFP模块,CFP模块可选用CFP-2020控制器,该控制器本身可以作为一个计算机终端,可以通过局域网设置,通过一个局域网中的任何一台计算机对CFP 控制器进行控制,即对“虚拟实验室”进行远程控制与操作。 [0043] Because the test system is based CFP modules, CFP module can be used CFP-2020 controller, which itself can be used as a computer terminal, you can set up a local area network, a local area network by any computer on the CFP controller control, namely the "virtual laboratory" for remote control and operation.
