Lubricating oil regeneration device of waste internal-combustion engine

Abstract

The invention relates to a lubricating oil regeneration device of a waste internal-combustion engine, belonging to the technical field of regeneration device structures. The lubricating oil regeneration device comprises a pretreatment tank of raw materials; the pretreatment tank of the raw materials is connected with a first-stage heat exchanger which is connected with a first-stage distiller; the first-stage distiller is connected with a first-stage cooler and a first-stage waste oil tank; the firs-stage cooler is connected with a first-stage finished product oil tank which is connected with a first-stage intermediate oil tank which is connected with a second-stage heat exchanger; the second-stage heat exchanger is connected with a second-stage distiller which is connected with a second-stage cooler and a second-stage waste oil tank; the second-stage cooler is connected with a second-stage finished product oil tank which is connected with a second-stage intermediate tank; the second-stage intermediate tank is connected with a third-stage heat exchanger which is connected with a third-stage distiller; and the third-stage distiller is connected with a third-stage finished product oil tank and a third-stage waste oil tank. The invention has reasonable structural design and can thoroughly separate and purify light and heavy base oil components in the waste lubricating oil.

Description

technical field [0001] The invention relates to a regeneration device for lubricating oil of a waste internal combustion engine, which belongs to the technical field of regeneration device structures. Background technique [0002] Lubricating oil is widely used in transportation, manufacturing, rubber and plastics, chemical industry and other industries. With the growth of the national economy, its demand and consumption are also increasing. At present, the annual sales volume of lubricating oil in China has exceeded 5 million tons, and it is increasing every year. The rate of increase of more than 13% means that at least 4 million tons of waste lubricating oil are produced every year, and there is a trend of continued growth. The quality control of lubricating oil in the use process is particularly important. Since the use process is inevitably "polluted" by mechanical high temperature, waste water, metal and other powder impurities, the waste oil that is replaced when it i...

Problems solved by technology

The quality control of lubricating oil in the use process is particularly important. Since the use process is inevitably "polluted" by mechanical high temperature, waste water, metal and other powder impurities, the waste oil that is replaced when it is off-line is burned as fuel oil and cannot be recycled. The first Waste of resources, the second increases the cost of the enterprise, and the third is when fuel oil is burned and pollutes the environment

[0003] Lubricating oil will inevitably be mixed with a small amount of water and mechanical impurities during the working process. These impurities will cause the viscosity of the lubricating oil to rise, emulsification, and affect the cooling and lubrication effects. The carbon chains of these polymer heavy oil components are continuous at high temperatures. It is easy to break, leading to symptoms such as lubrication failure, and new oil needs to be replaced immediately. At present, there is no research on the processing and regeneration of base oil in lubricating oil
