| titleOfInvention | SCR (selective catalytic reduction) denitration control method based on control strategy optimization |
| abstract | The invention relates to an SCR denitration control method based on control strategy optimization, which adopts a cascade denitration control strategy, wherein a main regulation controller is set to be outlet NOx concentration and used for stabilizing the concentration of denitration outlet NOx at a set value, a regulating quantity is required ammonia flow, a secondary regulation controller is used for controlling the target required ammonia amount and regulating the output to be the opening degree of an ammonia spraying valve, the dynamic characteristics of a system are ensured by adding a feedforward action, and the method comprises the calculation of ammonia nitrogen molar ratio, inlet NOx fold line function optimization, variable lower limit variable parameters and trackable design and CEMS instrument maintenance anti-interference design, solves the problem of large system deviation, adjusts the CEMS instrument maintenance time-varying cascade to be single PID adjustment, and counteracts the interference on the system generated during CEMS instrument sampling, blowing and maintenance. The mode of variable parameter, variable lower limit and variable feedforward action is adopted to eliminate inlet NO X System for large fluctuationThe resulting disturbance. And an auxiliary PID control module is introduced to shield the influence of the valve characteristics on the regulation quality, and the problem that the air preheater is easily blocked due to overhigh ammonia escape is solved. |
