The Functions of the Separator Drum in Batch-type Waste Tire Pyrolysis

Preliminary separation of heavy oil

During the batch-type pyrolysis process, the high-temperature oil and gas generated by the pyrolysis of waste tires contains a large amount of heavy oil components. After the oil and gas enters the separator drum, its flow rate drops significantly. The heavy oil with higher density settles at the bottom of the separator drum under the action of gravity, achieving preliminary separation of heavy oil from light oil vapor, pyrolysis gas and water vapor. This step can prevent heavy oil from directly entering the subsequent condensation system and avoid pipeline blockage caused by the solidification of cooled heavy oil.

Buffering oil and gas and stabilizing process parameters

Batch-type pyrolysis features obvious batch periodicity, and the oil-gas output, temperature and pressure fluctuate sharply during the three stages of heating-up, pyrolysis and cooling. The separator drum can serve as a buffer vessel to balance the delivery rhythm of oil and gas, alleviate pressure fluctuations in subsequent processes, provide stable gas source conditions for subsequent procedures such as condensation separation and gas recovery, and ensure the stable operation of the entire batch-type equipment.

Ensuring the safe operation of subsequent equipment

In addition to separating heavy oil, structures such as baffles and wire meshes inside the separator drum can also capture a small amount of solid impurities entrained in the oil and gas. This can reduce the abrasion and blockage of subsequent equipment including condensers, oil pumps and gas compressors, extend the service life of the equipment, and lower the frequency and cost of equipment maintenance in batch-type production.
