The invention discloses a coupling system for capturing carbon dioxide in flue gas and mineralizing carbon dioxide based on industrial solid waste, comprising: an adsorption reaction device, flue gas is input into the adsorption reaction device and is subjected to an adsorption reaction with an adsorbent arranged in the adsorption reaction device, and a first carbonate product is generated; the first carbonate product is subjected to thermal decomposition treatment by the thermal decomposition device to generate oxide and carbon dioxide; returning the oxide to the adsorption reaction device again for circular reaction; inactivated and scrapped oxides are conveyed into an industrial solid waste mineralization system to participate in reaction; the carbon dioxide is conveyed into an industrial solid waste mineralization system to participate in the reaction. According to the system and the method, capture of CO2 in flue gas and an industrial solid waste mineralization system can be coupled, the two processes are coupled, capture and utilization of carbon dioxide are achieved, waste recycling is achieved, high-quality chemical products can be produced, meanwhile, a flue gas CO2 capture production line is also easily and organically combined with a production line of the industrial solid waste mineralization system, and the process cost is reduced.
Description
technical field [0001] This application belongs to the fields of hydrometallurgy technology, carbon capture, utilization and storage (Carbon Capture, Utilization and Storage), and solid waste resource utilization, and specifically relates to a coupling system of carbon dioxide capture in flue gas and industrial solid waste-based carbon dioxide mineralization . Background technique [0002] The common carbon dioxide capture method in flue gas, taking the calcium cycle method as an example, is currently a very promising process for carbon dioxide capture in the industry. It can also be integrated with steel plants, power plants, cement plants or lime plants; at the same time, the CO recovered 2 High purity, easy to collect, store and transport. Calcium cycle method to absorb CO 2 The core principle is to utilize CaO and CO 2 The reversibility of the reaction enables a continuous cycle of carbonation / calcination to achieve CO 2 capture. [0003] CaO+CO 2 →CaCO 3 ΔH=-17...
