Claim 0:
1. A flue gas low-temperature adsorption denitration method, comprising: pressurizing a flue gas that has been subjected to dust removal and desulfurization, precooling pressurized flue gas, cooling precooled flue gas to a temperature lower than room temperature by a flue gas cooling system (1), flowing the flue gas at the temperature lower than room temperature into a low-temperature denitrification system (2), performing physical adsorption denitrification in the low-temperature denitrification system (2), precooling the flue gas that has been subjected to dust removal and desulfurization with denitrificated flue gas, and flowing heat-absorbed clean flue gas into a chimney to be discharged.
