Multi-process flue gas purification system and its control method

摘要

The present invention discloses a multi-process flue gas purification system and a control method therefor, wherein the centralized desorption subsystem and the sintering process subsystem are installed in a sintering process to form an integrated structure with the adsorption subsystem of the sintering process. It allows the activated carbon circulating between them to complete the cycle through the transport device group, and does not require additional transport equipment, thereby saving transport resources and at the same time weakening the impact on the system operation during transport. In the present invention, the concentrated desorption subsystem includes a material distribution device, and distributes the activated carbon to the adsorption subsystem of the sintering process through the first material distribution member, the activated carbon flow rate of the concentrated desorption subsystem, the adsorption subsystem of the sintering process, and the remaining adsorption The equilibrium relationship between the concentrated desorption subsystem and the adsorption subsystem on the side of the concentrated desorption subsystem by making the activated carbon flow rates of the subsystems equalize with each other and setting the operating parameters of the material intake device, the material discharge device and the material distribution device of the concentrated desorption subsystem to achieve precise control over
