Intelligent dynamic partition ammonia spraying control method and system

The invention provides an intelligent dynamic partition ammonia spraying control method and system. The method comprises an intelligent total amount control method and an intelligent partition controlmethod. The invention further provides an ammonia spraying system using the method. The ammonia spraying system comprises a DCS system module, a PLC controller module and a big data analysis module.The DCS system module is connected with the PLC controller module through an LC card by adopting a MODBUS communication protocol, and the PLC controller module is connected with the big data analysismodule through a TCP/IP protocol. The ammonia spraying total amount of the denitration reactor can be effectively controlled, the ammonia spraying uniformity can be guaranteed according to the branchpipe adjusting valves, ammonia escape is effectively reduced, and the purpose of environment-friendly emission is achieved. 本发明提供了一种智能的动态分区喷氨控制方法和系统，该方法包括智能总量控制方法和智能分区控制方法。本发明还提供了一种利用上述方法的喷氨系统，包括DCS系统模块、PLC控制器模块和大数据分析模块；所述DCS系统模
