Dissolvent refining equipment for producing environment-friendly rubber filling oil

The utility model belongs to the technical field of petrochemical industry, and discloses dissolvent refining equipment for producing environment-friendly rubber filling oil. An extraction tower of the equipment is provided with a raffinate oil inlet or a residual liquid inlet as well as an extract oil inlet. The raffinate oil inlet or the residual liquid inlet is arranged at a lower part from a raw material oil inlet to a dissolvent inlet of the extraction tower; and the extract oil inlet is arranged at a circulatory extraction outlet at the bottom of the extraction tower. With the dissolvent refining equipment, under the condition that heavy lubricating oil dissolvent extract oil is taken as raw material oil, ring-less environmental-friendly aromatic hydrocarbon can be remained, and toxic polycyclic aromatic hydrocarbon can be removed, so that higher aromatic hydrocarbon-content environmental-friendly rubber filling oil which meets the European Union environmental protection instruction requirement can be produced.
