Abstract: This disclosure provides a system for coupling supercritical carbon dioxide cycle power generation and lithium extraction from brine. The system comprises an absorption heat pump unit, a supercritical carbon dioxide cycle power generation unit, and a unit for extracting lithium from brine. This system organically couples the exothermic characteristics of the supercritical carbon dioxide cycle system with the endothermic characteristics of the lithium extraction from brine system, and the waste heat is recycled in a cascade as the heat source in the lithium extraction from brine system, thereby effectively reducing the total energy consumption of power generation and lithium extraction and reduce the total equipment investment of the system, and significantly improving the efficiency of adsorption and lithium precipitation in the lithium extraction from brine system.

Abstract: A recycling system includes a reaction kettle, a stirring device, and an electromagnetic device. The reaction kettle is provided with a liquid inlet, a gas inlet, a liquid outlet, and a slag discharge port. The stirring device is arranged on the reaction kettle. The stirring device includes a stirring rod and at least one stirring paddle. One end of the stirring rod extends into the reaction kettle, and the at least one stirring paddle is arranged on the end of the stirring rod. The electromagnetic device includes a first electromagnetic coil, and the first electromagnetic coil is wound on an outer circumferential surface of the reaction kettle. The arrangement of the stirring device allows the geothermal water to fully contact with the gas, which is conducive for the suspension of the ferroferric oxide in the geothermal water.
