The invention provides a device for CO2 mineralization curing of concrete blocks. The device comprises a gas storage tank, a gas mixer, a heater, a supercharger, a pressure buffer tank and a still kettle. An inlet of the gas mixer is communicated with an outlet of the gas storage tank, and the gas mixer is used for mixing CO2 and air to adjust the CO2 concentration. An inlet of the heater is communicated with an outlet of the gas mixer. An inlet of the supercharger is communicated with an outlet of the heater. An inlet of the pressure buffer tank is communicated with an outlet of the supercharger. And an inlet of the still kettle is communicated with an outlet of the pressure buffer tank. The device provided by the invention can accelerate flue gas flow and disturbance, compensates for the insufficient CO2 concentration in the center of each concrete block, increases the probability and improves the efficiency of the mineralization reaction in the center of each concrete block. Flue gas can be continuously co
