Direct air carbon capture system and method
The invention discloses a direct air carbon capture system and method. The system comprises an alkali liquor absorption and regeneration integrated device, a heat pump system, an ager, a calcining furnace, a condensation separator and a compressor, the alkali liquor absorption and regeneration integrated device consists of a shell, an arched biomass carbon material gas absorption plate, a barren liquor tank, a particle reaction tank, a filter and a solution pump; cO2 absorption occurs on the surface of the biomass carbon material gas absorption plate, and directional transfer of barren liquor and rich liquor is realized due to capillary action, siphonage generated by height difference of a barren liquor tank and a particle reaction tank and ion concentration difference; the heat pump system not only recovers water vapor in decarburized air, but also is used for primary preheating of CaCO2; caO curing reaction heat is used for secondary preheating of CaCO3. By utilizing the pore structure, capillarity and siphonic effect of the biomass carbon material gas absorption plate, the CO2 absorption rate is improved, and the pump work is saved. The heat pump system is used for saving water resources. And system energy consumption is reduced by using system waste heat.
