The pyrolysis of waste plastics produces a small amount of solid residue containing fixed carbon, which has secondary utilization value. Traditional treatment mostly involves direct transport for disposal, which not only increases solid waste removal costs but also causes resource waste. A complete residue treatment process can achieve compliant collection and secondary utilization of residues, improving the closed-loop production system. Henan Yongle Group has optimized the residue collection and treatment structure of plastic refining equipment and provided an orderly residue collection system, helping plants achieve closed-loop resource utilization of materials.

The plastic refining equipment is equipped with a closed automatic residue discharge structure. The solid residue after pyrolysis can be discharged smoothly, with the entire process operating in a sealed manner, avoiding workshop pollution caused by residue dust and scattering, keeping the production area clean and tidy, and meeting environmental production standards.

The residue discharge rate of the equipment matches the pyrolysis rhythm, allowing residue cleaning to be completed without affecting furnace conditions. Residual solid material in the furnace is discharged promptly, preventing residue accumulation from affecting subsequent pyrolysis reactions and ensuring continuous and stable operation of the production line.

The collected pyrolysis residue has a stable composition and uniform calorific value. It can be used as auxiliary fuel for plant heating, drying and other processes, or applied in fields such as building material auxiliary materials, realizing secondary monetization of waste materials and improving the resource utilization rate of the entire project.

The standardized centralized residue treatment mode reduces the discharge of solid waste from the plant, lowers the pressure of compliant solid waste disposal, simplifies solid waste ledger registration and management processes, and meets the requirements of routine environmental inspections.

Relying on a complete closed-loop residue treatment system, the plastic refining equipment achieves full-chain resource treatment of waste plastics, from raw material disposal and oil production to residue utilization, improving the solid waste recycling system and supporting the green and long-term operation of the project.
