Non-blast furnace smelting reduction ironmaking process method

The invention discloses a non-blast furnace smelting reduction ironmaking process method which comprises the following steps: conveying an iron-containing material into a smelting furnace through a first injection assembly, conveying biomass carbon into the smelting furnace through a second injection assembly, and discharging coal gas discharged by reduction ironmaking reaction of the iron-containing material in the smelting furnace and the biomass carbon into a second injection assembly; and the carbon dioxide is conveyed to the first injection assembly and the second injection assembly through the carbon dioxide removal facility. The carbon dioxide removal facility is used for removing carbon dioxide in coal gas and conveying the carbon dioxide to the first injection assembly and the second injection assembly, the first injection assembly is used for injecting iron-containing materials into the smelting furnace, and the second injection assembly is used for injecting biomass carbon into the smelting furnace
