The recycling methods of waste transformer oil mainly include the following:
- Filtration: Remove solid particles and impurities in the oil through mechanical filtration.
- Centrifugal separation: Use centrifugal force to separate water and solid impurities in the oil.
- Vacuum dehydration: Heat the oil under vacuum conditions to remove water and gas.
- Acid treatment: Use sulfuric acid or other acidic substances to remove acidic impurities and oxides in the oil.
- Alkali treatment: Use alkali to neutralize the acidic substances in the oil, and then remove the generated saponification by washing.
- Adsorption treatment: Use adsorbents such as activated clay and silica gel to remove polar substances and impurities in the oil.
- Electrical purification: Remove tiny particles and colloidal substances in the oil through the action of the electric field.
- Thermal polymerization: Polymerize unstable substances in the oil at high temperature, and then remove them by filtration.
- Distillation: Separate different components in the oil by distillation to remove light and heavy impurities.
- Multi-step treatment: Combine multiple methods for treatment, such as physical filtration first, chemical treatment, and finally vacuum dehydration.
- Biodegradation: Use microorganisms to degrade organic pollutants in oil, suitable for treating waste oil containing biodegradable substances.
1. Pretreatment: Remove large particles and moisture.
2. Deep treatment: select appropriate chemical or physical methods for deep purification according to the specific pollution of the oil.
3. Post-treatment: Perform vacuum dehydration, filtration and other steps to ensure the purity of the oil.
4. Quality inspection: Perform quality inspection on the recycled oil to ensure that it meets the use standards.
- Safe operation: Pay attention to safety when handling waste oil and avoid contact with harmful substances.
- Environmental protection requirements: The treatment process should meet environmental protection requirements to avoid secondary pollution.
- Economic efficiency: When selecting a treatment method, economic efficiency should be considered to ensure the cost-effectiveness of recycling.
Through the above methods, waste transformer oil can be effectively recycled, reducing resource waste and environmental pollution.
