Multi-process flue gas purification system and control method

摘要

The present invention provides a multi-process flue gas purification system and a control method thereof. The flue gas purification system includes an activated carbon intensive desorption activation sub-system (2) and flue gas purification devices (110, 120) corresponding to each process. One flue gas purifier (110, 120) is connected to the activated carbon intensive desorption activation subsystem (2) through the activated carbon transport subsystem (3), respectively. The main control unit represents the activated carbon circulating flow rate of the activated carbon concentrated desorption activation sub-system 2 using the total sum of the activated carbon circulating flow rates sent by the process control units corresponding to all processes, and controls the activated sub-system control unit 102 By adjusting the given frequency of the belt scale 26, the material supply device 22, and the material discharging device 24 in the activated carbon desorption activation subsystem 2, the activated carbon circulating flow rate of the activated carbon desorption activation subsystem 2 And the total sum of the activated carbon circulating flow rates of the flue gas purifiers 110 and 120 in each process is substantially the same.
