The utility model discloses production equipment for biodiesel with a low acid value. The production equipment comprises an adsorption column, a biodiesel header tank, a methanol header tank, a receiving groove and a pipeline, wherein the adsorption column is internally filled with D301-FC macroporous adsorbing non-polar resin; the biodiesel header tank and the methanol header tank are connected to an inlet of the adsorption column through the pipeline; and the receiving groove is connected to an outlet of the adsorption column through the pipeline. The production equipment has the advantages that the D301-FC macroporous adsorbing non-polar resin is used for adsorbing an acidic material, so that the acid value can be reduced below 0.6, and the production equipment is simple, convenient to operate, low in operation cost and suitable for massive continuous operation. |
