Faced with the increasing amount of medical waste, how to safely and environmentally recycle it and achieve resource utilization is a global concern. As a manufacturer of environmental protection equipment, HUAYIN medical waste pyrolysis equipment provides an innovative solution. This article will provide detailed answers to several key questions about pyrolysis of medical waste to oil.
1. Can medical waste be pyrolyzed to produce oil?
Not all medical waste is suitable for pyrolysis to oil. The core of pyrolysis technology is to convert organic waste into energy. Therefore, the efficiency of medical waste to oil depends entirely on its organic content. Medical waste rich in polymers (such as plastics and rubber) is an ideal feedstock for oil production, while other types of waste are primarily targeted for harmlessness and reduction.
2. Which medical waste can be pyrolyzed to oil?
To achieve a high oil yield, the selection of raw materials is crucial. Medical waste most suitable for oil production via pyrolysis includes:
- Plastic medical waste: Disposable IV bags, IV tubing, plastic IV bottles, syringe casings (excluding needles), etc. These items are primarily composed of PP and PE and are the primary contributors to pyrolysis oil.
- Rubber medical waste: Discarded medical gloves, rubber tubing, bottle stoppers, etc.
In contrast, cotton balls, gauze, and human tissue, while harmless, have a low oil yield due to their high water and cellulose content. Inorganic materials such as metals and glass are separated as residue.
3. What are the working steps of HUAYIN medical waste pyrolysis equipment?
HUAYIN medical waste pyrolysis equipment mainly includes the following working steps:
- Feeding: Collected medical waste is fed into the sealed pyrolysis reactor via an automatic feeding system.
- High-temperature pyrolysis: In the hypoxic environment, the reactor is heated to a high temperature (typically 400-500°C). The macromolecular chains of organic matter in the medical waste are broken, vaporizing to form oil and gas.
- Oil and gas cooling: The generated high-temperature oil and gas enter a specialized cooling system, condensing into liquid pyrolysis oil, which is then collected in a storage tank.
- Exhaust gas purification and utilization: After purification, the uncondensed combustible gas is partially recycled into the combustion chamber to power the pyrolysis process, achieving energy self-sufficiency. Excess gases and flue gases are treated through a rigorous purification system to ensure compliance with emission standards.
- Slag discharge: After the reaction is complete, the solid matter remaining in the reactor (carbon black/residue) is automatically discharged for separation and recovery.
4. Can the oil produced by medical waste pyrolysis be used directly?
The oil directly produced by medical waste pyrolysis equipment is a “crude” or “unrefined” oil, similar in properties to industrial crude oil. It cannot be used directly in engines or generators. It is characterized by high impurities, high viscosity, and instability.
This pyrolysis oil must be processed before use:
- Simple Application: After initial filtration, it can be used directly as an industrial fuel, replacing heavy oil in cement plants, boilers, asphalt plants, etc.
- Processing Application: To be used as diesel, it must undergo a series of refinery processes, including distillation, refining, bleaching, and deodorization, to produce non-standard diesel suitable for construction equipmentry or generators.
