China News Service, Beijing, March 1 (Guo Chaokai) A reporter learned from the Sixth Institute of China Aerospace Science and Technology Corporation on March 1 that China’s first on-board plasma medical waste disposal system developed by 11 institutes has successfully passed principle verification recently. .

The system adopts the most advanced plasma gasification and melting process in the field of waste disposal in the world, and realizes the mobile rapid harmless, clean and zero-discharge treatment of medical waste and epidemic-related organisms. It provides strong technical support for dealing with public health emergencies, and fills the gaps in domestic related technologies.

In recent years, major public health emergencies such as the new crown pneumonia epidemic have occurred from time to time. A large number of medical wastes and organisms involved in the epidemic prevention and control period may cause secondary pollution in the process of circulation and treatment, which is a prominent problem in epidemic prevention and control. The market has an urgent need for a miniaturized mobile medical waste disposal system that is flexible, mobile, clean, environmentally friendly, and highly efficient.

After nearly a year of collaborative innovation, the R&D team has successively overcome five major problems such as size limitation and environmental adaptability, completed the prototype development and successfully passed the principle verification test. Only need to supply water and electricity, a single 12-meter container prototype has a processing capacity of 2 tons/day.

According to the introduction by Han Xianwei, head of the Shaanxi Provincial Key Laboratory of Plasma Physics and Applied Technology and Director of the Plasma Technology Center of the Sixth Academy of China Aerospace Science and Technology Corporation, the system adopts high-end equipment with independent intellectual property rights-large The power plasma torch injects a high-temperature plasma jet with a core temperature of nearly 10,000 degrees into the gasification furnace to melt the pollutants to form glass slag, thereby achieving harmless disposal.

Currently, plasma gasification molten waste disposal technology has been popularized and applied in the fields of garbage disposal, cinder disposal, and sludge disposal. Compared with traditional incineration methods, this technology has high processing temperature, fast processing speed, and thorough processing. It is suitable for almost all medical wastes and epidemic-related organisms. The products are very friendly to the human body and the environment, and have considerable economic benefits and environmental protection after being put into production. benefit.

The Sixth Academy of China Aerospace Science and Technology Group stated that after a simple transformation, the on-board plasma medical waste disposal system can be widely used in various scenarios that require high flexibility, high harmlessness, and high treatment efficiency, such as Disposal of toxic chemical leakage, waste treatment in scenic spots, crop pest control and disaster mitigation, drug and drug disposal, and waste treatment of field troops, etc., have a very broad prospect.
