This application discloses a multi-process flue gas purification system and its control method, including activated carbon centralized analysis and activation subsystem, and flue gas purification devices corresponding to each process. Focus on analyzing the connection of activation subsystems to realize the recycling of activated carbon. The main control unit uses the sum of the activated carbon circulation flow sent by the process control units corresponding to all processes to represent the activated carbon circulation flow of the activated carbon centralized analysis and activation subsystem, and controls the activation subsystem control unit to adjust the activated carbon centralized analysis and activation subsystem. The given frequency of the material device and the discharge device makes the activated carbon circulation flow at the activated carbon centralized analysis and activation subsystem substantially equal to the sum of the activated carbon circulation flow of the flue gas purification device in each process, thereby making the adsorption part of the multi-process flue gas purification system The purpose of synchronous operation with the parsing part is achieved, and the operating efficiency is improved.
Description
Technical field [0001] This application relates to the field of gas purification technology, and in particular to a multi-process flue gas purification system and its control method. Background technique [0002] Iron and steel enterprises are the pillar enterprises of the entire national economy. However, while making important contributions to economic development, they are also accompanied by serious air pollution problems. There are many processes in iron and steel enterprises that produce flue gas emissions, such as sintering, pelletizing, coking, ironmaking, steelmaking, and steel rolling. The flue gas emitted by each process contains a large amount of dust and SO. 2 And NO X And other pollutants. After the polluted flue gas is discharged into the atmosphere, it not only pollutes the environment, but also poses a threat to human health. For this reason, iron and steel enterprises usually adopt activated carbon flue gas purification technology, that is, the flue gas purific...
