Abstract: Provided are a drawer-type carbon capture solvent purification and recovery device and method. The recovery device includes a support, a mounting frame and a purification module, the purification module is connected in an insertable manner to the mounting frame along the outer periphery of the mounting frame at equal intervals, and two adjacent purification modules are communicated with each other. The left half of the mounting frame forms a purification region, and the right half of the mounting frame forms a regeneration region. A liquid to be filtered sequentially flows through all purification modules in the purification region from top to bottom and then is discharged from a liquid outlet pipe.

Abstract: A hydrophobic MOF-based porous liquid carbon capture absorbent is provided and includes a sterically hindered solvent and a hydrophobic MOFs modified material dispersed in the sterically hindered solvent. A mass percent of the hydrophobic MOFs modified material in the hydrophobic MOF-based porous liquid carbon capture absorbent is 5% to 20%. The hydrophobic MOFs modified material is prepared by a method comprising following steps: dispersing an MOFs material, a surface modifier and a catalyst in an organic solvent, and mixing them evenly, followed by a standing reaction to obtain the hydrophobic MOFs modified material.

Abstract: The disclosure relates to the technical field of carbon dioxide capture, in particular to a carbon dioxide capture tower, which includes a pre-washing impurity removal section, a carbon dioxide absorption section and a flue gas washing section being sequentially arranged from bottom to top in a vertical direction, so that flue gas sequentially flows through the pre-washing impurity removal section, the carbon dioxide absorption section and the flue gas washing section. A carbon dioxide capture tower flue gas inlet is arranged on the pre-washing impurity removal section, and a carbon dioxide capture tower flue gas outlet is arranged on the flue gas washing section. The purpose of this disclosure is to provide a carbon dioxide capture tower aiming at the technical problems that the manufacturing cost of the flue gas carbon dioxide capture system is high and the workload of later operation, overhaul and maintenance is large.

Abstract: A recovery method of absorption solvent waste liquid and a CO2 capture method are provided. The recovery method includes providing mixed slurry of adsorbent and absorption solvent waste liquid; and performing reaction on the mixed slurry at 60-150° C. under ultrasonic and sealing conditions; wherein the adsorbent is solid waste containing alkaline substances. According to the disclosure, solid waste containing alkaline substances is used as an adsorbent to treat the absorption solvent waste liquid, so that toxic and carcinogenic diethylene glycol and other harmful substances formed by self-polymerization in the absorption solvent waste liquid can be adsorbed on the solid waste, and the removal rate can reach more than 88%. After this treatment, the obtained absorption solvent waste liquid can be recycled. In addition, the use of solid waste as adsorbent has low production cost, and the waste can also be used as solid waste.
