What is High-Temperature Dry Heat Treatment
High-temperature dry heat treatment is a widely used method for medical waste sterilization. It utilizes high temperatures to inactivate microorganisms and pathogens in medical waste, while reducing its volume and weight through processes like dehydration. The treatment effectively makes medical waste harmless and reduces its environmental impact.
Key Conditions for High-Temperature Dry Heat Treatment
Equipment Required for High-Temperature Dry Heat Treatment
Sterilizer
Typically made from high-temperature, corrosion-resistant metals such as stainless steel. These materials ensure the equipment's durability and safety, as they must withstand high heat and exposure to various chemicals in medical waste.
Piping
For the pumping unit, corrosion-resistant materials such as PVC or metal piping lined with resistant coatings are used to prevent damage from pressure fluctuations and exposure to hazardous gases.
Equipment Size
Equipment size is determined based on treatment volume and space availability. Small-scale equipment for medical clinics may have a capacity of a few cubic meters, while large-scale systems for treatment centers can handle dozens of cubic meters.
Grinder
The grinder must be made from high-hardness, abrasion-resistant materials like special alloys or hard ceramics to prevent excessive wear during the grinding of medical waste.
Features of High-Temperature Dry Heat Treatment
Sterilization
By maintaining a temperature between 180°C and 200°C for a specified duration, the treatment effectively kills pathogens, including bacterial spores, viruses (e.g., Hepatitis B, HIV), and fungi. This ensures a safe environment and prevents disease transmission.
Volume Reduction
Medical waste volume can be reduced by 80% after grinding, making it easier to handle, transport, and store. After treatment, the waste is converted into fine particles or fragments suitable for landfill or further processing.
Small-scale
The high-temperature environment facilitates evaporation of moisture, further reducing the waste's weight and volume. This enhances waste disposal efficiency and minimizes leachate generation in landfills.
Advantages of High-Temperature Dry Heat Treatment
Operational Process
Disposal After Use
Equipment Cleaning and Maintenance
The equipment must be regularly cleaned to remove waste debris and prevent clogs. Regular inspections ensure the optimal performance of key components like the mill and heating system.
En savoir plusLandfilling
After treatment, the waste is sent to a landfill. The landfill must meet certain standards, such as proper depth and cover layer thickness, to prevent re-exposure of treated waste to the environment.
En savoir plusPrecautions During Operation
01
Equipment Inspection
Before each operation, check the sealing of the bin door, mill wear, and the performance of the vacuum and heating systems to prevent equipment failure.
02
Classification des déchets
Properly classify medical waste before treatment to avoid mixing in flammable or explosive substances that could cause hazards during the process.
03
Standardized Operation
Operators must follow strict procedures and wear appropriate personal protective equipment (PPE), such as gloves, masks, and protective clothing, to prevent exposure to hazardous waste.
04
Parameter Monitoring
Constantly monitor temperature, pressure, and time during the treatment process to ensure compliance with operational requirements. Adjust or halt the process if parameters deviate.
Principaux éléments à prendre en compte lors du choix de l'équipement
Performance
Choose equipment with precise temperature control, stable vacuum performance, and efficient grinding capabilities to ensure high sterilization efficiency.
Reliability
Consider equipment durability, failure rates, and after-sales service. Reliable equipment reduces operating and maintenance costs.
Environmental Impact
Check if the equipment meets environmental standards for exhaust gas and wastewater discharge. Ensure it has effective tail gas filtration and wastewater treatment systems.
After-Sales Support
Choose equipment from manufacturers that provide comprehensive after-sales support, including installation, training, regular maintenance, and spare parts supply.
International Standards and Regulations
Lignes directrices de l'OMS
The World Health Organization advocates for medical waste treatment methods that ensure complete inactivation of pathogens and follow safety standards to protect human health and the environment.
Chinese Regulations
China’s regulations require that high-temperature dry heat treatment facilities comply with national standards. Treatment processes must be conducted following prescribed procedures, and waste discharge must meet environmental protection standards.
Leading Manufacturers
Europe & North America: High-temperature dry heat treatment technology is widely used in medical waste treatment centers across these regions. Chine: Manufacturers like Xinhua Medical et Jiangsu Huaxing Medical Equipment Co., Ltd are major suppliers of medical waste treatment equipment, offering tailored solutions to meet regional needs.
