description The utility model relates to the field of chemical production, and particularly provides an organic pigment crude solvent recovery processing system. Comprising a crude solvent tank, a first delivery pump, a methanol rectifying tower, a methanol refining tower and a deamination tower, the output end of the first delivery pump is connected with a ceramic membrane filter, clear liquid filtered by the ceramic membrane filter enters the methanol rectifying tower, insoluble impurities in a crude solution are filtered and separated through the ceramic membrane filter, and the crude solution is obtained. After the impurities are filtered and the impurities dissolved in the solvent are concentrated and separated out, the impurities are separated in a filter pressing manner, so that the impurities are prevented from entering a subsequent rectification process; gas evaporated in the methanol rectifying tower is condensed by a condenser and then sent to a methanol refining tower, the bottom of the methanol rectifying to
