The invention relates to a method for ironmaking by a novel blast furnace. A pressure-swing absorption apparatus and a blast furnace ironmaking device are combined and applied. Carbon monoxide is enriched from blast furnace coal gas by the pressure-swing absorption apparatus after cooling and removing dust, and the enriched carbon monoxide returns to the blast furnace from different parts of the blast furnace. The invention not only lowers coke consumption during the ironmaking process and reduces the coke rate and the energy consumption for ironmaking by the blast furnace, but also solves the problem that utilization rate of the blast furnace coal gas is low. The invention reduces the emission of harmful gas, such as the carbon monoxide, carbon dioxide and the like and is good for the environmental protection. Under proper condition, the coke rate can be reduced from 420kg/t to 180kg/t by the method to the maximum.
