Description

Technical Field

[0001] The invention relates to the technical field of medical waste disinfection, and in particular to a medical waste microwave disinfection device. Background Art

[0002] Medical waste refers to waste that is directly or indirectly infectious, toxic or otherwise hazardous and is generated by the medical and health system during medical, preventive, health care and other related activities.

[0003] The application of microwave technology in medical waste treatment is based on the principle of using microwave energy for heating and disinfection. When electric microwaves pass through medical waste, they cause the water molecules in the waste to vibrate at high speed, generating frictional heat, thus achieving the effect of high-temperature sterilization. Microwave technology can efficiently kill bacteria, viruses and other pathogens in a relatively short time. This is because microwave energy directly acts on the water molecules in the waste, causing them to heat up rapidly, destroying the cell structure of the pathogens and making them inactive. This efficient sterilization ability makes microwave technology an ideal choice for treating infectious medical waste. Secondly, microwave technology has high energy utilization. Microwave energy can directly act on the water molecules in the waste with almost no energy loss, so the sterilization efficiency is very high. Compared with traditional thermal treatment sterilization methods, microwave technology can reach the required high temperature faster, thereby improving treatment efficiency.

[0004] The existing microwave disinfection treatment system for medical waste is mainly composed of a feeding unit, a crushing unit, a disinfection treatment unit, a discharging unit, an automatic control facility, an exhaust gas treatment unit and a steam supply unit. The disinfection treatment unit uses a closed screw conveyor to transport the crushed medical waste. During the transportation, the microwave generator and the steam generator work together to treat the transported medical waste with microwaves, and the sterilization and disinfection of the medical waste is completed under the conditions of ensuring a certain temperature and residence time. Although the existing microwave disinfection device has a certain disinfection effect on medical waste, due to the characteristics of the spiral conveying structure, the medical waste particles are squeezed and compressed during the transportation process, the porosity is reduced, and the high-temperature steam (absorbing electromagnetic waves, assisting in heating, and improving the disinfection effect) introduced cannot fully contact with the medical waste, and the steam introduced is often concentrated on the upper part of the cylinder of the disinfection device, and cannot be well contacted with most of the medical waste located at the bottom of the screw conveyor.
