Safety Assurance of Batch-Type Pyrolysis Oil Extraction Equipment

Safety Assurance of Batch-Type Pyrolysis Oil Extraction Equipment

I. Design and Process Prevention

Sealed Explosion-Proof Design: The furnace is a pressure vessel equipped with explosion-proof flanges and sealing gaskets, with pressure resistance testing conducted on key components.

Oxygen-Free Environment: Nitrogen purging is applied throughout the process, and sealed valves are used for feeding and slag discharge to prevent air from entering the furnace.

Overpressure & Overtemperature Protection: Equipped with multi-stage safety valves and rupture discs; automatic power cutoff/feed stop is triggered in case of overtemperature.

II. Real-Time Operation Monitoring

Key Parameter Monitoring: Real-time monitoring of furnace temperature, pressure, and oxygen content; automatic alarms and interlock protection are activated when parameters exceed safe thresholds.

Leak Detection: Combustible gas detectors are installed at potential leak points, triggering immediate alarms and feed cutoff upon detection of leaks.

Automatic Interlock System: The heating source is automatically cut off in case of overtemperature or overpressure, and an emergency shutdown is initiated if the cooling system fails.

III. Emergency Response and Protection

Fire Protection Facilities: Equipped with foam fire extinguishers, fire water cannons, and an emergency vent flare.

Standardized Operation: Strict operating procedures are established, with regular safety training and emergency drills conducted.

Regular Maintenance: Pressure vessels undergo annual third-party inspections, and safety accessories are calibrated periodically.
