Waste hydraulic oil treatment refers to the process of treating and utilizing waste hydraulic oil.
Hydraulic systems are widely used in industrial production and construction machinery, and waste hydraulic oil will cause environmental pollution and waste of resources.
Waste hydraulic oil treatment has become an important environmental protection work.
1.Reasons for waste hydraulic oil disposal: There are two main reasons for the generation of waste hydraulic oil.
First, due to the influence of long-term use and working environment, hydraulic oil will gradually reduce its performance indicators, such as increased viscosity, increased foam, oxidation and deterioration.
Second, in the process of maintenance and replacement of mechanical equipment, the old hydraulic oil needs to be discharged in order to replace the new hydraulic oil.
2.Methods of waste hydraulic oil treatment: Waste hydraulic oil treatment can be carried out by physical methods, chemical methods or physicochemical methods.
Physical methods mainly include filtration, centrifugal separation and distillation.
Chemical methods mainly include additives, neutralizers and solvents.
The physicochemical method is a combination of multiple methods.
3.Steps of waste hydraulic oil treatment: The steps of waste hydraulic oil treatment are as follows: (1) Collection and storage of waste hydraulic oil: Collect waste hydraulic oil and store it in a special container for subsequent treatment.
2) Preliminary filtration of waste hydraulic oil: The physical filtration method is used to carry out preliminary filtration of waste hydraulic oil through filtration equipment to remove particle impurities.
3) Chemical treatment of waste hydraulic oil: add an appropriate amount of chemical additives, such as antioxidants, anti-wear agents, etc., to improve the performance of waste hydraulic oil.
4) Comprehensive treatment of waste hydraulic oil: Physicochemical methods, such as centrifugal separation, distillation, etc., are used to comprehensively treat waste hydraulic oil to restore its original performance.
5) Reuse of waste hydraulic oil: The treated hydraulic oil can be reused to reduce resource waste and environmental pollution.
4.The significance of waste hydraulic oil treatment: The significance of waste hydraulic oil treatment is to protect the environment and save resources.
If the waste hydraulic oil is not treated, it will cause water and soil pollution and affect the health of the ecological environment.
Through the treatment of waste hydraulic oil, it can not only reduce the emission of pollutants, but also make use of waste hydraulic oil and improve resource utilization.
5.Prospect of waste hydraulic oil treatment: The development of waste hydraulic oil treatment technology has broad prospects.
With the process of industrialization and urbanization, the application of hydraulic system will be further expanded, and the amount of waste hydraulic oil will increase accordingly.
The development and application of efficient, economical and environmentally friendly waste hydraulic oil treatment technology will become an important research direction in the future.
Waste hydraulic oil treatment is an important environmental protection work, through the use of physical, chemical and physicochemical methods to treat waste hydraulic oil, waste and reuse of waste hydraulic oil can be realized, reduce resource waste and environmental pollution.
With the wide application of hydraulic system, the development prospect of waste hydraulic oil treatment technology is very broad.
We should strengthen the research and application of relevant technologies to promote the in-depth development of waste hydraulic oil treatment.
