基于PLC的转炉除尘控制系统设计中文摘要本文介绍了转炉除尘的基本工艺和流程，并设计了基于PLC的清灰、输灰控制系统。首先分析烟气除尘的要求和工艺，了解国际技术现状，确定了设计方案。采用西门子S7-300PLC与WINCC作为整个控制系统的核心控制设备。根据实际生产和工艺要求，完成了整个控制系统的硬件组态、输入输出点分配、PLC程序编写以及监控界面设计。最后根据控制要求设计自动运行、手动以及换模三种状态的PLC程序，并联合WINCC仿真调试，基本实现了转炉烟气除尘的功能，完成了任务书上的设计要求。关键词除尘，清灰，输灰，PLC，WINCC外文摘要TitleTheDesignoftheControlSystemforConverterdedustingBasedonPLCAbstractThispaperintroducesthebasicprocessandprocessofconverterdedusting,anddesignsthecontrolsystembasedonPLC.Firstly,therequirementsandprocessoffluegasdedustingwereanalyzed,andthedesignschemewasdetermined.AdoptSiemenss7-300plcandWINCCasthecorecontrolequipmentofthewholecontrolsystem.Accordingtotheactualproductionandprocessrequirements,thehardwareconfiguration,inputandoutputpointdistribution,PLCprogrammingandmonitoringinterfacedesignofthewholecontrolsystemarecompleted.Accordingtothecontrolrequirementsdesignautomaticoperation,manualandPLCprogramthreestatesofthemould,andjointWINCCsimulationdebugging,basicallyachievedthefunctionofthededustingofconverterfluegas,completedthetaskdesignrequirementsofthebook.Keywordsdustremoval,dustcleaning,dusttransport,plc,wincc目录1引言.................................................................11．1课题来源与课题意义..............................................11．2转炉除尘技术的国内外发展状况简介与方法选择......................11．3预期结果........................................................22转炉除尘系统概述.....................................................22．1除尘工艺说明....................................................22．2设备简介........................................................32．3控制设备选择....................................................42．4设计内容与步骤..................................................43系统设计.............................................................43．1系统概述........................................................43．2系统I/0点号表..................................................63．3控制设备的选型.................................................174软件程序............................................................174．1除尘程序.......................................................174．2清灰程序.......................................................194．3卸灰程序.......................................................244．4故障操作方式...................................................255监控画面及其功能....................................................256综合调试............................................................306．1仿真连接.......................................................306．2调试...........................................................316．3实现的功能.....................................................35结论.................................................................37致谢.................................................................38参考文献............................................................391引言1．1课题来源与课题意义自21世纪以来，钢铁冶金行业发展飞速。钢铁冶炼的同时会产生大量高温烟气，包含大量有毒气体和粉尘等物质，如果不加处理直接通过烟囱排放到空气中，那不仅会对大...
