This invention discloses a high-efficiency catalytic conversion device and method for CO2 in lime kiln tail gas of steel plants. The high-efficiency catalytic conversion device for CO2 in lime kiln tail gas of steel plants includes a tail gas collection unit, an impurity adaptive pretreatment unit, a waste heat classification and utilization unit, a CO2 catalytic conversion unit, a product separation unit, and a circulation regulation unit arranged sequentially along the tail gas flow direction. The impurity adaptive pretreatment unit has a composite filter bag dust removal module that can remove dust and SO2 from the tail gas and a priority oxidation reforming module that can oxidize part of the CO in the tail gas to CO2. The waste heat classification and utilization unit divides the tail gas waste heat into three levels through a heat exchanger and a heat distribution controller. The low-temperature waste heat is used for preheating before the CO2 catalytic conversion of the raw material gas, the medium-temperature waste heat is used for reaction heating in the methanation reactor, and the high-temperature waste heat is used for electrolysis power supply in the solid oxide electrolysis cell. This can realize the on-site high-efficiency capture and high-value conversion of CO2 in lime kiln tail gas, which is very suitable for the existing energy conditions of steel plants.
