Embodiment 1
[0033] Firstly, the flue gas after denitrification, dust removal and desulfurization is pressurized by the booster fan, and then enters the absorption reactor containing amine solid adsorbent, and the CO in the flue gas 2 Adsorbed by amine solid adsorbent, the resulting clean flue gas is discharged into the atmosphere. absorbed CO 2 The amine solid adsorbent enters the regeneration reactor for regeneration treatment. The reasonable regeneration method is to remove CO from flue gas by amine solid adsorbent. 2 The key to technology. The regeneration method can have the following options, as attached figure 1 shown. (1) Thermal regeneration. Provide heat to the regeneration reactor to increase the temperature of the regeneration reactor, so that the temperature of the regeneration reactor is higher than that of the absorption reactor, so that the CO adsorbed by the amine solid adsorbent 2 It can be effectively desorbed, so that the amine solid adsorbent can be reused. (2) ...
