Production Process Flow
- Raw-material Pre-treatment and Compatibility: Different waste types go through manual sorting to remove non-pyrolyzable foreign substances, then fed into the pre-treatment unit for shredding, screening and drying. Compatibility mixing is performed according to calorific value, moisture content and heavy-metal content of waste. Homogenized feedstock meeting pyrolysis requirements is stored in raw-material silos. For hazardous waste, stabilization pre-treatment is conducted simultaneously to immobilize heavy metals and decompose toxic-harmful substances.
- Sealed Feeding into Reactor: Materials from silos are delivered into the pyrolysis reactor via sealed explosion-proof feeding devices. The feeding port is fully closed and sealed after charging to guarantee air-tight, oxygen-free and negative-pressure conditions inside the reactor and prevent escape of toxic-harmful gas.
- Flexible Temperature-controlled Pyrolysis: The combustion chamber ignites for heating. While rotating, the reactor follows pre-set multi-stage heating profiles. Waste completes pyrolysis reactions within the optimal 350-450 °C temperature window for organic-chain cleavage and oil-gas release. Heavy-metal immobilization and toxic-substance decomposition are realized simultaneously.
- Oil-gas Purification and Condensation: Oil-gas generated from pyrolysis is separated via gas headers and delivered into multi-stage tubular condensers. Fast heat exchange and liquefaction are realized by forced circulating-water cooling. Liquid pyrolysis oil flows into oil-storage tanks; non-condensable gas enters the combustible-gas purification system.
- Combustible-gas Recycling: Purified combustible gas passes through explosion-proof flame arrestors and feeds into the combustion chamber as heating fuel to substitute external energy sources and realize on-site energy self-sufficiency. Surplus combustible gas can be collected and stored for other on-site energy-consumption purposes for circular-energy utilization.
- Residue Stabilization Treatment: Heating stops upon completion of pyrolysis. The reactor keeps rotating for accelerated cooling. When furnace temperature drops to a safe level, pyrolysis residues are discharged through sealed slag-removal devices. After cooling, residues go into stabilization units for further immobilization of heavy metals and toxic substances, producing stabilized residues compliant with landfill standards for safe landfilling or resource recovery.
- Deep Flue-gas Purification & Discharge: Flue gas exhausted from the combustion chamber sequentially passes through desulfurization tower, denitrification unit, activated-carbon-adsorption tower and catalytic-combustion unit for deep purification. Pollutants including acid gas, heavy metals, dioxins and organic waste gas are removed. Treated gas is released through explosion-proof chimneys after reaching emission standards, with smokeless, odor-free and non-toxic exhaust throughout the workflow.
- Product Storage & Utilization: After passing inspection, pyrolysis oil stored in tanks, collected combustible gas and stabilized residues can be sold directly or reused on-site, completing full-chain harmless treatment, volume reduction and resource recovery of waste.
