Zusammenfassung:The embodiment of the invention provides a method for recovering BDO and inhibiting a BDO hydrogenation side reaction through a GBL device, and relates to the field of BDO recovery and BDO hydrogenation side reaction inhibition. The method for recovering the BDO and inhibiting the BDO hydrogenation side reaction by the GBL device comprises the following steps: step 1, crude GBL obtained by dehydrogenation reaction enters a vacuum light component removal tower through a pipeline, and light components in the crude GBL are removed through the vacuum light component removal tower; according to the method, valuable chemicals can be recycled, considerable economic benefits can be brought to enterprises by recycling BDO in the heavy components at the bottom of the high-boiling tower, and meanwhile, the BDO solution containing GBL is introduced into the second-stage high-pressure hydrogenation reactor; the invention has the advantages of inhibiting the generation of side reaction GBL, dissolving polymer in the second
