The invention discloses a fiber separation type saturated oil separation recovery device and method for base oil solvent extraction extract, the device comprises a cooler and a fiber separator which are connected in sequence, the fiber separator comprises a shell, the shell is provided with a liquid inlet, a liquid outlet, a gas inlet and a deoiling port which can be controlled to be opened and closed, the liquid inlet is used for being connected with the cooler, and the gas inlet is used for being connected with the deoiling port. The air inlet is used for introducing hot air, the deoiling opening is used for discharging saturated separated oil, the shell is filled with fiber yarns, and meanwhile, an extrusion plate for extruding the fiber yarns is arranged. According to the method, the solubility of the NMP solvent is reduced, the selectivity is improved and the saturated oil contained in the extract is released from the NMP solvent by adopting a cooling means, and then the saturated oil adsorbs and swells the cellosilk and the NMP solvent and the unsaturated oil are discharged by adopting a fiber separation technology, so that the saturated oil is separated, the loss of base oil is avoided, and the extraction efficiency is improved. The overall yield of the base oil is improved; the whole process is good in stability, low in operation cost and high in efficiency.
Description
technical field [0001] The invention relates to the technical field of waste lubricating oil treatment, in particular to a fiber separation type saturated oil separation recovery device and method for base oil solvent extraction liquid. Background technique [0002] Lubricating oil is composed of base oil and a certain amount of additives. After a period of use, lubricating oil will lose its normal function due to the introduction of impurities and deterioration of additives, and become waste lubricating oil. Waste lubricating oil contains saturated oil (light component base oil, as the reason component) and unsaturated oil, and also contains impurities such as sludge, metal particles, carbon black, water, additives and degradation products. [0003] With the development of technology and the improvement of environmental protection requirements, waste lubricating oil can be processed to obtain regenerated base oil. The main process includes distillation and extraction. The w...
