The intelligent SCR denitration control system is a kind of control system that realizes the high efficiency, stability and optimization of SCR denitration by adopting advanced control strategy and technical means. SCR denitrification technology is a kind of nitrogen oxide (NOx) emission control technology widely used in thermal power plants, industrial boilers and other fixed pollution sources. Under the action of the catalyst, NOx in the flue gas is reduced to harmless ammonia and water. Intelligent SCR denitration control system adopts advanced control strategies and technical means to achieve efficient, stable and optimized control of SCR denitration.
The SCR denitration PLC control system of Guangdong Green Valley environmental protection technology Co., LTD is mainly composed of data processing module, data acquisition module, control strategy module, actuator module and human-computer interaction module. In the SCR denitration process, the PLC control system is responsible for monitoring and adjusting various key parameters to ensure that the equipment efficiently and stably reduces NOx emissions.
1. Data collection and recording. The process of data acquisition is to collect the temperature, NOx concentration, pressure, flow rate and other parameters of the flue gas in real time by installing various sensors in the SCR denitration system, and transmit these data to the data processing module. Through real-time analysis and processing of data acquisition, the accuracy and reliability of data are ensured, including data filtering, outlier detection, and data fusion.
2. Data analysis and control. According to the processed data, the control module needs to use the current control algorithm to calculate the appropriate control parameters such as the amount of ammonia spray, the number of catalyst layers, and the flue gas flow rate, so as to realize the optimal control of the SCR denitration process. According to the control parameters calculated by the control strategy module, the ammonia injection valve and flue gas regulating valve are adjusted in real time to control the denitration process of SCR.
3. User interface. Through the form of human-computer interaction, the operator can monitor the operation of the system in real time through the touch screen, and can view various parameters and alarm information at any time, and can manually adjust and intervene in the adjustment operation.
4. Fault diagnosis and safety. Through the analysis and mining of the system operation, it is necessary to continuously optimize the control, improve the denitration efficiency and stability of the system, and also need to have perfect safety protection measures to protect the excessive ammonia injection and the overheating of the catalyst, to ensure the safe and reliable operation of the system.
5. Remote access. The PLC control system of Guangdong Green Valley environmental protection technology Co., LTD can be remotely monitored and controlled, so that relevant managers can access the system from any location through a network connection.
6. System integration and scalability. The PLC control system of Guangdong Green Valley environmental protection technology Co., LTD can be integrated with the management system of other factories to achieve data sharing and overall optimization, and more control modules and functions can be added according to demand.
Intelligent SCR denitrification system, through real-time monitoring, real-time acquisition, processing and analysis of data, using today’s control strategy and actuator control, to achieve efficient, stable and optimized control of SCR denitrification process, reduce NOx emissions.
