Problems solved by technology

But for the medium and high viscosity waste oil (kinematic viscosity is 100-460mm 2 / s), because of its high viscosity and density, and the lack of mature treatment technology, it can only be used as low-grade oil after simple processing for a long time, and cannot achieve high-level recycling.
This is not only an economic waste, but also may cause environmental pollution

Embodiment Construction

[0030] Purification and regeneration process flow of the present invention is as figure 1 shown.

[0031] Now the present invention will be further described in conjunction with an embodiment and a process flow diagram.

[0032] Box 1: Recycled used oil feedstock

[0033] The recovered waste oil referred to in the present invention refers to the recovered waste oil mixed with various high-viscosity lubricating oils, such as waste hydraulic oil, waste gear oil, waste bearing oil, etc., and their properties are quite different due to different recycling channels. The stock oil of the present invention is the waste oil that this enterprise reclaims, and its original data adopts the statistical value of the test data of all the waste oils that reclaim in a period of time, promptly is based on the lower limit of the average value, in production according to its actual situation The fluctuation range is adjusted.

Abstract

The present invention relates to the utilization of waste resource, and especially the regeneration and utilization of mixed waste oil of high and medium viscosity. The purification and regeneration process of waste oil of high and medium viscosity includes the following steps: natural deposition and rough filtration; heating for flocculation and deposition; three stages of pre-treatment including the secondary filtering; low temperature and high vacuum dewatering and fine filtering; inspection, etc. Through the purification and regeneration process, the produced oil product may reach the standard of new oil product.

Description

technical field [0001] The invention relates to the development and utilization of waste resources, in particular to the regeneration and utilization of mixed waste oil, especially mixed waste oil with medium and high viscosity. Background technique [0002] General production enterprises will produce a certain amount of waste oil. A large enterprise produces a considerable amount of waste oil a year. For example, Shanghai Baosteel will produce thousands of tons of waste oil every year. The low viscosity (kinematic viscosity at 100mm 2 / s or less) the waste oil treatment process is relatively mature. But for the medium and high viscosity waste oil (kinematic viscosity is 100-460mm 2 / s), because of its high viscosity and density and the lack of mature treatment technology, it can only be used as low-grade oil after simple processing for a long time, and cannot achieve high-level recycling. This is not only an economic waste, but also may cause environmental pollution. C...
