The utility model discloses a catalyst-recovering and furfuryl-alcohol clarifying device in the production process of furfuryl alcohol, which is characterized by comprising a furfuryl-alcohol crude-product storage tank, a delivery pump and a ceramic-membrane filtering assembly, wherein the furfuryl-alcohol crude-product storage tank, the delivery pump and the ceramic-membrane filtering assembly are sequentially connected through feeding pipelines, a ceramic membrane is installed in the ceramic-membrane filtering assembly, a dialysis-fluid outlet of the ceramic-membrane filtering assembly is connected with a dialysis tank through a dialysis pipeline, and a concentrated-fluid outlet of the ceramic-membrane filtering assembly is connected with the furfuryl-alcohol crude-product storage tank through a reflow pipeline. By adopting the catalyst-recovering and furfuryl-alcohol clarifying device, the removal rate of a furfuryl-alcohol catalyst can reach more than 99 percent, the catalyst separating effect of the cata
