The invention provides a catalytic reduction denitrifying device for removing liquid phase at an ultralow temperature. Through a reduction tower and a catalyzing system, industrial glue gas containingSO2 and NOX is fed into a catalyzing device, and a liquid phase catalyst in the catalyzing device is atomized through an atomizing spray gun and is fully mixed with the industrial flue gas, so that NOx molecules in the flue gas in contact with the liquid phase catalyst are captured and molecular chains of the molecules are broken to form N.O<+> to finish the denitrifying catalytic reaction. The flue gas after the denitrifying catalytic reaction enters the reduction tower, a spraying device in the reduction tower conveys a liquid phase reducer in the reduction system to the top of the reduction tower, and the flue gas moves from bottom to top and the reducer moves from top to bottom to form a convection impact, so that the flue gas and the reducer are mixed fully to finish desulfurizationand denitrification reacti
