The invention belongs to the technical field of energy and environment protection, and particularly relates to a high-temperature catalytic combustion device and method for liquid nitrogen washing tail gas. The high-temperature catalytic combustion device for the liquid nitrogen washing tail gas can achieve high-temperature combustion of the liquid nitrogen washing tail gas, recycled heat is high, the recycled heat can be fully utilized, the using range of the heat is widened, and energy saving and emission reducing are achieved. The high-temperature catalytic combustion device is small in equipment number, small in investment cost, low in running cost, small in energy consumption, and easy, convenient and safe to operate. The high-temperature catalytic combustion device is wide in application range of heat recycled for treating the liquid nitrogen washing tail gas, direct conveying to a pulverized coal drying device is achieved, and drying for pulverized coal is achieved; and conveying to sites needing steam
