The invention discloses a method for extracting pure nitrogen from polluted nitrogen high in extraction rate and low in energy consumption. The method includes the following steps that polluted nitrogen enters a main tower and then conducts heat and mass transfer with top-to-bottom liquid on a tower plate or fillers in the main tower from bottom to top, part of pressure is pumped out at the tower top, and the polluted nitrogen serves as a product after being reheated through a main heat exchanger; after polluted liquid nitrogen discharged from the bottom of the main tower enters a subcooler to be cooled through the subcooler, polluted nitrogen evaporated from a main tower condenser is sent to a secondary tower, the polluted nitrogen conducts heat and mass transfer with top-to-bottom liquid on a tower plate or fillers in the secondary tower from bottom to top, the polluted nitrogen generated at the tower top is condensed through a secondary tower condenser, part of the condensed liquid returns to the secondary tower to serve as backflow liquid, and the other part of the liquid enters the main tower to serve as backflow liquid; the polluted nitrogen evaporated from the secondary tower condenser is reheated through the subcooler and the main heat exchanger, and then is sent to a polluted nitrogen compressor to be recycled and utilized. According to the method, the amount of the nitrogen extracted from the polluted nitrogen is higher than the amount of the nitrogen extracted from the air, and the nitrogen extraction rate reaches more than 90%.
