Abstract (en)
[origin: WO2022096049A1] The invention relates to a device for cleaning an exhaust gas mixture volume flow, more particularly comprising solvents, more particularly organic solvents, more particularly NMR (N-methylpyrrolidone), for use in a continuous cyclical cleaning process, comprising: a main cleaning stage and a fine cleaning stage, wherein, following the main cleaning stage, the exhaust gas mixture volume flow can be split by means of a splitting means into a main volume flow, which is to be guided back to a point upstream of the main cleaning stage, more particularly upstream of an upstream drying unit particularly for coated cathode materials, and a secondary volume flow, which is to be guided through a fine cleaning stage, wherein the main cleaning stage comprises at least one condensate cleaner, wherein the fine cleaning stage comprises at least two adsorption wheels, particularly two-stage adsorption wheels, configured for the adsorption of solvent, particularly NMR, which are arranged one after the other in series, wherein an output flow from the fine cleaning stage is to be guided via a return line, particularly back to a point upstream of the main cleaning stage.
