Products Description
Continuous Plastic Pyrolysis Plant
This Continuous Plastic Pyrolysis Plant is a full-automatic continuous industrial-grade complete-set disposal equipment specially designed for various waste-plastic materials. It is compatible with shredded and cleaned plastic fragments and plastic granules, with a daily processing capacity of 20-60 tons. Under sealed slight-negative-pressure conditions, the complete unit realizes 24-hour continuous feeding, pyrolysis and carbon-slag discharging, stably producing plastic pyrolysis oil, carbon slag and combustible tail gas. The system adopts special structural optimization targeting plastic melting and coking characteristics. It suits large-scale waste-plastic volume-reduction projects in industrial parks and achieves industrial continuous resource-oriented treatment of waste plastics.

Features
Anti-melting-coking sealed lock-feeding system:
Equipped with pre-heating anti-blocking feeding chamber and multi-stage air-locking sealing mechanism to tackle plastic melting and sticking under heat. It ensures stable and continuous feeding of plastic materials into the furnace and prevents air back-flow.
Multi-temperature-zone sectional pyrolysis reaction chamber:
The chamber is divided into melting-gasification zone, deep pyrolysis zone and residue-drying zone with independent temperature control for each zone. Plastics complete melting, macromolecule cracking and residue dehydration step-by-step, mitigating furnace-blocking risks caused by plastic coking.
Negative-pressure sealed carbon-slag discharging & cooling unit:
Pyrolysis residues are discharged under full-process negative-pressure sealed conditions and indirectly cooled by water cooling with air isolated. It avoids re-ignition of residues upon oxygen exposure, and residues are discharged only after cooling to lower safety risks.
Integrated PLC+DCS intelligent control system:
Feeding speed, zone-wise temperature, furnace negative pressure and oil-gas output flow are centrally monitored. Coking early warning as well as over-temperature and over-pressure interlock protection are configured, supporting remote data access.
Integrated tail-gas graded-reuse & flue-gas-purification module:
Combustible tail gas generated by pyrolysis is preferentially fed back to the furnace as heat source, and excess tail gas can be exported for recovery. A supporting flue-gas-purification unit treats post-combustion exhaust gas to meet emission-control requirements.
Advantages
Optimized for plastic-melting properties for long-term continuous operation:
Different from tyre pyrolysis equipment, it specially addresses pain points of plastic hot-melting wall-sticking and furnace clogging. Frequent shutdown for coke cleaning is unnecessary, making it suitable for large-volume non-stop waste-plastic production.
Slight-negative-pressure sealed process to reduce oil-gas-leakage risks:
The furnace chamber maintains slight negative pressure. Air-lock sealing is adopted throughout material feeding and discharging to minimize oil-gas escape with low on-site odour, facilitating safety and environmental-protection audits in industrial parks.
Tail-gas self-heating source to greatly cut external energy consumption:
Combustible tail gas yielded from plastic pyrolysis serves directly as furnace heating fuel, sharply reducing consumption of coal, natural gas and other external fuels and lowering project operating costs.
Intelligent early-warning & interlock to ease manual-attendance burden:
Automatic alarm and interlock actions are triggered for coking, over-temperature and abnormal pressure. On-site human intervention is reduced, and failure risks such as furnace clogging and over-heating caused by plastic material properties are mitigated.
Wide material compatibility for mixed waste plastics: Pre-treated mixed waste plastics including PP, PE, PS can be processed without strict sorting. It broadens raw-material sources and improves the project's risk-resistance capacity.
Application Scenarios
- Waste-plastic disposal section for large-scale circular-economy industrial parks: Specialized treatment of municipal domestic-waste plastics and industrial waste plastics within solid-waste industrial parks to realize large-volume volume reduction and resource recovery.
- Industrial projects for leading plastic-recycling enterprises: Recycling enterprises processing tens of thousands of tons of waste plastics annually build continuous production lines for stable sales of pyrolysis oil output.
- Overseas industrial-investment solid-waste projects: For overseas industrial investors with sufficient raw-material supplies to dispose of domestic-waste and industrial waste plastics and pursue stable 7×24-hour mass production.
- Plastic-hazardous-waste disposal unit for hazardous-waste-treatment centres: Treat oil-contaminated and impurity-laden plastic hazardous waste and complete the plant-wide solid-waste-disposal chain.
- Pre-treatment project supporting oil-refining industry: Produced plastic pyrolysis oil can be used as feedstock for oil refineries and connected to downstream deep-processing production lines.
Packing & Shipping
Continuous Plastic Pyrolysis Plant is large-scale complete-set industrial equipment. It is split into multiple independent functional modules for bare-metal separate shipment: anti-blocking feeding module, sectional pyrolysis main reactor, sealed slag-discharge cooling unit, DCS electric-control cabinet, tail-gas-reuse system and oil-gas-purification module are transported separately.
Protective blind plates are installed on all flange interfaces and thread positions are coated with anti-rust grease. DCS control cabinets, transmitters and precision measuring instruments are packed in thickened waterproof wooden cases. Sealing assemblies, anti-stick wear-resistant liners, wearing spare parts and special tools are individually packed in wooden crates. Steel-structure components are anti-corrosion-treated with primer plus double-layer weather-resistant topcoat.
Standard modules fit into 40HQ containers; extra-large heavy-duty structural parts are delivered by bulk carrier. Lead-time for standard configuration: 120 days upon receipt of advance payment; 130 days for customized high-capacity and advanced oil-gas-purification versions. Trade terms including EXW, FOB and CIF are supported. Packing lists, equipment dimension-and-weight sheets, general-layout drawings, civil-construction construction drawings and process-flow diagrams can be provided to support overseas customers for customs clearance, plant infrastructure construction and on-site module assembly & commissioning.
FAQ
Q1: What pre treatment requirements are imposed on incoming raw materials for Continuous Plastic Pyrolysis Plant?
A: Raw materials shall be shredded and cleaned to remove sediment and impurities and processed into plastic fragments or granules. Monolithic bulky plastics cannot be fed directly. Excessive impurities will aggravate coking and shorten continuous operation cycles.
Q2: Compared with tyre pyrolysis, what are the key maintenance differences for plastic pyrolysis?
A: Plastics are more prone to melting and wall sticking. Priority shall be given to monitoring feeding temperature and reaction temperature of each zone. Regular inspection for material sticking inside feeding chamber and scheduled maintenance in accordance with operating procedures are required. Long term over load operation is prohibited.
Q3: How many operators are required for the whole production line?
A: Under DCS central control mode, 2 4 operators per shift are required, mainly responsible for central control monitoring and on site inspection. Additional personnel are needed for the raw material pre treatment section.
Q4: How to handle the generated carbon slag residues?
A: Cooled carbon slag can be sold externally as auxiliary fuel. Follow up deep processing equipment can be configured according to customer requirements.
Q5: Can this equipment process mixed feed of plastics and tyres?
A: High proportion mixed feeding is not recommended, as the pyrolysis working conditions of plastics and tyres differ greatly. Customized design for material working conditions is required in advance if mixed processing is needed.
