Core Equipment for the Pyrolysis Section of an Oil Sludge Pyrolysis Refinery

Core Equipment for the Pyrolysis Section of an Oil Sludge Pyrolysis Refinery

The equipment in the pyrolysis section is configured around four core requirements: reaction, material conveying, heat recycling, and safety assurance, and mainly includes:

1. Core Pyrolysis Reactors

Horizontal Rotary Pyrolysis Furnace: The most mainstream model, with a closed rotating structure that ensures uniform heating of materials. Suitable for daily processing capacities of 10–100 tons, ideal for high-viscosity, impurity-containing oil sludge.

Fluidized Bed Pyrolysis Furnace: Features high heat transfer efficiency and fast reaction speed, suitable for large-scale projects with daily processing ≥50 tons, but requires strict control of raw material particle size.

Internal Heating Vertical Pyrolysis Furnace: High thermal energy utilization and uniform temperature distribution, suitable for small-to-medium projects and low-impurity oil sludge.

2. Feeding and Slag Discharge Equipment

Closed Screw Feeder: Dual-screw structure enables continuous and uniform feeding, while isolating air to avoid safety risks.

Water-Cooled Closed Slag Discharger: Cools and discharges high-temperature residues, ensuring system airtightness and operational safety.

3. Heat Recycling and Temperature Control Equipment

Gas Purification System: Purifies combustible gas generated during pyrolysis, removing dust and tar to prevent burner blockages.

Burner + Heat Exchanger: Uses purified gas to heat the furnace, achieving energy self-sufficiency and improving thermal efficiency.

PLC Temperature Control System: Real-time monitoring of furnace temperature and pressure to ensure stable reaction operation.

4. Safety Assurance Equipment

Nitrogen Protection System: Fills the furnace with nitrogen during startup, shutdown, or abnormal conditions to isolate oxygen and prevent explosions.

Pressure Safety Valve + Emergency Vent Device: Automatically relieves pressure when furnace pressure is abnormal to avoid equipment damage.
