Oil Purifier Operating Procedure

The operation of an oil purifier, typically used for waste oil treatment, oil filtration, or oil regeneration, generally involves several steps to ensure efficient separation of contaminants (such as solids, water, and other impurities) from the oil. Below is a general operation procedure for an oil purifier, especially those utilizing centrifugal force (like oil centrifuges).

 Oil Purifier Operation Procedure 

--- 

 1. Preparation:

- Inspection and Setup:

  - Ensure that the oil purifier is properly installed and connected to the power supply.

  - Check the system’s components (pumps, centrifuge drum, inlet and outlet valves, filters) for any visible damage or wear.

  - Verify that all safety protocols are in place, including emergency stop buttons, correct pressure settings, and proper sealing.

- Verify Oil Type:

  - Ensure the waste oil to be processed is compatible with the oil purifier’s design.

  - Confirm that the oil does not contain any foreign objects that could damage the system.

- Ensure Proper Oil Levels:

  - Check the oil level in the tank. The purifier typically requires a certain amount of oil to work efficiently (neither too little nor overfilled).

---

 2. Pre-Filtration (if applicable):

Some oil purifiers include a pre-filtering stage to remove larger particles before the oil is sent to the centrifuge for finer separation.

- Install Pre-Filters: If the oil is highly contaminated, install any required mesh filters or strainers.

- Start the Pre-Filtration Process: Allow the pre-filters to remove larger solid particles before the oil enters the main purifier system.

---

 3. Start the Purifier:

- Start the Centrifuge:

  - Power on the oil purifier, ensuring that the centrifuge is rotating at the recommended speed (usually between 2,000–8,000 RPM, depending on the system).

  - The centrifugal force generated will begin to separate contaminants from the oil.

- Introduce the Waste Oil:

  - Open the inlet valve to feed the waste oil into the purifier system. The oil is usually pumped into the centrifuge at a consistent rate.

  - The waste oil is typically introduced into the centrifugal drum at the center, where it will start spinning.

---

 4. Separation Process:

- Centrifugal Force:

  - As the centrifuge spins at high speed, the denser impurities (such as water, sludge, dirt, and metals) will be forced toward the outer wall of the bowl or drum, while the lighter purified oil will move toward the center.

- Layer Formation:

  - The oil forms a cleaner layer in the center of the drum.

  - Solids (sludge) accumulate at the outer edges or in the collection chamber.

  - Water (if present) may separate into its layers depending on the specific oil being purified and the contaminants.

---

 5. Separation and Discharge:

- Solid Waste Removal:

  - The separated solid waste (sludge) that accumulates in the outer layers will either be manually or automatically discharged via a discharge port or sludge outlet.

- Water Separation (if applicable):

  - Some oil purifiers are equipped with a separate discharge port for water separation, allowing the water to be expelled from the system.

- Purified Oil Extraction:

  - The clean oil, now separated from solids and water, exits the centrifuge through the discharge port for purified oil.

  - This oil can be collected in a clean tank for reuse or further treatment if necessary.

---

 6. Monitoring and Adjustment:

- Monitor Parameters:

  - Check the operating parameters such as the flow rate, pressure, and centrifuge speed regularly to ensure everything is functioning within the recommended specifications.

  - Use a pressure gauge to monitor inlet and outlet pressure, ensuring that the system is not clogged or underperforming.

- Adjust Flow Rate:

  - Depending on the viscosity of the oil and the contamination level, adjust the flow rate to optimize the purification process.

- Sludge Collection:

  - Some systems may require periodic manual removal of collected sludge. Automated systems may discharge this waste at set intervals. 

--- 

 7. Final Inspection:

- Check Oil Purity:

  - Once the process is complete, check the purity of the discharged oil using visual inspection or testing tools. The oil should appear clearer and free of major particles or contaminants.

- Clean the System:

  - After processing, it's important to clean the oil purifier system to prevent contamination of future batches and ensure consistent performance.

  - Clean the centrifuge drum, discharge ports, filters, and any other components that may have accumulated residues.

---

 8. Shutdown:

- Turn Off the Centrifuge:

  - After the oil purification process is complete, power off the system, allowing it to come to a stop naturally.

- Close Valves:

  - Close the inlet and discharge valves to prevent contamination of future batches and ensure consistent performance.

Clean the centrifuge drum, discharge ports, filters, and any other components that may have accumulated residues.

8. Shutdown:

Turn Off the Centrifuge:

After the oil purification process is complete, power off the system, allowing it to come to a stop naturally.

Close Valves:

Close the inlet and discharge valves to prevent contamination when the system is off.

Maintenance:

Periodically check and ｒｅｐｌａｃｅ any worn-out parts (e.g., seals, filters, bearings).

Perform any necessary maintenance, such as lubrication or cleaning, to extend the life of the purifier.

Safety Considerations:

Always wear personal protective equipment (PPE), including gloves, safety goggles, and hearing protection when operating and maintaining the oil purifier.

Ensure that the system is grounded to prevent electrical accidents, especially when working with electrically powered centrifuges.

Always follow the manufacturer’s manual for specific operational and safety guidelines.

Types of Oil Purifiers:

Different types of oil purifiers can include:

Centrifugal Oil Purifiers: These are the most common, utilizing centrifugal force to separate impurities.

Vacuum Oil Purifiers: These use vacuum pressure to remove water and gases from oils.

Pressure Filtration Systems: Some purifiers utilize pressure filtration methods in addition to or instead of centrifugal force.
