Harmless Pyrolysis Treatment Technology for Hazardous Waste

According to the National Catalogue of Hazardous Wastes (2025 Edition) and relevant technical specifications, the treatment of hazardous wastes must be carried out in strict accordance with their hazardous characteristics—such as toxicity, corrosivity, flammability, reactivity, and infectivity—as well as their chemical composition, under a classified management system. The oxygen‑free pyrolysis technology developed by Jufeng Company is primarily suited for organic wastes, including those containing organic solvents, waste plastics, diatomaceous earth, metal scrap, and medical waste.

Thermal Decomposition Treatment for the Resource Utilization of Waste Phosphogypsum

After years of dedicated research and development, Henan Jufeng Technology Co., Ltd. has successfully developed a resource‑utilization and harmless treatment technology for waste phosphogypsum through thermal pyrolysis. This technology targets the byproduct of the phosphate industry—waste phosphogypsum—and employs an oxygen‑free pyrolysis process. By precisely controlling temperature (200–750°C) and the reaction environment, it achieves efficient conversion and resource recovery of solid waste.

Chain-plate anaerobic pyrolysis furnace

The chain‑plate pyrolysis furnace independently developed by Jufeng Company is a single‑layer, oxygen‑free pyrolysis furnace that employs continuous pyrolysis equipment driven by chain plates. Through technologies such as indirect heating, continuous conveyance, and zone‑specific temperature control, it achieves stable, efficient, and clean conversion of solid waste—making it particularly well suited for large‑scale, standardized solid waste treatment projects. The comprehensive advantages of the chain‑plate pyrolysis furnace in realizing “reduction, harmlessness, and resource utilization” have secured its important position in the field of solid waste treatment.

Multi‑stage Helical Pyrolysis Furnace (Molten Salt Pyrolysis Furnace)

After eight years of development and more than a dozen rounds of technical refinement, Jufeng Technology has independently developed molten salt pyrolysis equipment that utilizes molten salt as a heat transfer medium. The equipment is designed as a multi‑stage spiral‑push furnace, featuring an upper‑lower combined configuration with multiple sets of spirals that reciprocate back and forth. Materials enter from the top and exit from the bottom, while the heating method employs external heating of the spiral outer cylinder, with molten salt serving as the heat transfer medium.

Inner‑embedded mother–daughter pyrolysis furnace

Also known as: embedded twin‑rotor pyrolysis furnace, continuous twin‑rotor pyrolysis furnace, twin‑rotor oxygen‑free carbonization furnace, twin‑rotor carbonization furnace, embedded oxygen‑free pyrolysis rotary kiln, and more. After more than a decade of research and development, Henan Jufeng Technology has launched the “Inner–Outer Embedded Pyrolysis Furnace,” which represents a technological upgrade and optimization based on the single‑unit rotary pyrolysis furnace.

Electromagnetic Heating Rotary Pyrolysis Furnace

Building on the foundation of single‑unit rotary furnaces, Jufeng Technology has independently developed a technology that utilizes electromagnetic induction heating. By passing alternating current through coils wound around the exterior of the rotary furnace body, a high‑frequency magnetic field is generated within the induction coils. As the metal furnace body—typically made of heat‑resistant stainless steel, metal, semiconductor materials, or specialized alloys—enters this magnetic field, eddy currents are induced inside the furnace, generating heat through the formation of these swirling currents. This heating method acts directly on the material’s interior, effectively eliminating heat loss associated with conventional heating methods. Its advantages include energy efficiency, environmental friendliness, precise temperature control, and long equipment lifespan.
