Waste lubricating oil regeneration coagulation sedimentation composite equipment

Abstract

The invention relates to waste lubricating oil regeneration coagulation sedimentation composite equipment, which belongs to the field of waste lubricating oil regeneration. When waste oil liquid is subjected to regeneration treatment with a flocculation sedimentation method, the long sedimentation time after flocculation reaction is the main reason for low regeneration efficiency. The purpose of the invention is to design coagulation sedimentation composite equipment which is compact in structure, simple in process, reliable in operation, high in sedimentation efficiency, convenient in cleaning, and low in investment and running cost. The equipment of the invention mainly comprises two parts which are a blending flocculation device and a sedimentation device, and adopts an idea of adding a plurality of partition plates in the flocculation equipment to reduce the relative sedimentation distance. Compared with the existing equipment, the equipment of the invention organically combines the blending flocculation device and the sedimentation device, so as to reduce the floor area of the equipment, saves the manufacturing cost of the equipment, improves the efficiency of flocculation and sedimentation. According to the equipment of the invention, the structure is scientific and simple, the design is reasonable and reliable, the floor area is small, the cleaning of sedimentation impurities is convenient, pollutants can be well removed, and the quality of regenerated lubricating oil is improved, resulting in a high practical value.

Description

technical field [0001] The invention relates to waste lubricating oil regeneration coagulation settling equipment, which belongs to the field of waste lubricating oil regeneration. Background technique [0002] When using the flocculation sedimentation method to regenerate the waste oil, the long sedimentation time after the flocculation reaction is the main reason for the low regeneration efficiency. It often takes several hours to several days to settle with the existing ordinary settling device, and with the increase of the processing capacity, the settling distance becomes larger, which further prolongs the time required to complete the settling, making the waste oil regenerated by flocculation settling method industrial applications are limited. [0003] During the working process of the engine, the lubricating oil is catalyzed by temperature, various media, metals, etc., and gradually decays to produce various oxidation products that are harmful to the engine, namely ...
