Why Intermittent Pyrolysis Equipment Is Recommended for Waste Plastic to Oil

Why Intermittent Pyrolysis Equipment Is Recommended for Waste Plastic to Oil

1. Low Investment, Fast Payback, Low Risk

• Intermittent equipment has a simple structure and much lower cost than continuous equipment.

• It covers a small area with simple supporting facilities, reducing civil engineering and installation costs.

• Suitable for small and medium investments; a complete production line can be set up with hundreds of thousands to over one million RMB.

• The payback period is generally 1–2 years, with low financial pressure.

Continuous equipment often costs millions to tens of millions RMB, with high requirements for raw materials, capital, and management, which is too risky for new investors.

2. Low Requirements for Raw Materials, Wide Adaptability

Waste plastics and tires collected in practice are mixed materials:

• Irregular sizes

• Uneven moisture content

• Containing soil, impurities, iron wires, and rubber

• Complex components (mixed PE/PP/PET/PVC, etc.)

Advantages of intermittent equipment:

• No fine crushing or strict sorting required.

• Can directly process blocks, whole tires, and mixed waste plastics.

• High tolerance to moisture and impurities.

Continuous equipment requires highly homogeneous, clean, and uniformly sized raw materials; slight defects in materials will cause blockage, machine jamming, and unstable oil output.

3. Simple Operation, Easy for Workers to Master

• Single reactor, batch operation with fixed process: feeding → sealing → heating → oil production → cooling → slag discharge.

• Moderate automation; ordinary workers can operate independently after a few days of training.

• Easy troubleshooting, simple maintenance, and low-cost spare parts.

Continuous equipment has a complex system with many instruments, interlocks, screws, seals, and temperature control systems; shutdowns cause huge losses.

4. Low Failure Rate, Easy Maintenance

The core components of intermittent equipment are:Pyrolysis reactor + combustion system + dust removal + condensation systemNo complex continuous conveying, sealing, or metering devices, so it hardly breaks down.

Continuous equipment runs nonstop for a long time, resulting in severe wear, high sealing requirements, and high maintenance costs and downtime risks.

5. Easier to Meet Environmental Standards and Obtain Permits

With strict environmental supervision, key indicators include:

• Flue gas treatment

• Leakage prevention

• Temperature control

Advantages of intermittent equipment:

• Closed operation of a single reactor, with centralized waste gas treatment.

• Stable combustion, making it easier to control dioxins, smoke, and dust.

• Mature structure with many cases for EIA (Environmental Impact Assessment) and safety assessment, smoother approval process.

The complex system of continuous equipment may easily cause emission problems if sealing or negative pressure control is poor.

6. Flexible Production, Suitable for Small Plants and Individual Investors

• Can run partially or shut down when raw materials are insufficient, no waste.

• Flexible working hours; can start or stop production as needed.

• Suitable for rural, township, and small recycling stations.

•
