Description

Technical Field

[0001] The utility model relates to the technical field of medical waste disinfection, in particular to a pre-disinfection system for medical waste disposal. Background Art

[0002] In traditional medical waste disposal processes, incineration is widely used as the primary method of disinfection. This technology, based on the principle of high-temperature combustion, involves placing medical waste into a high-temperature incinerator, where the high-temperature flames transform it into ash and flue gas. This method effectively kills bacteria and viruses that may be present in the waste, reducing the risk of infectious disease transmission. It also significantly reduces waste volume and saves storage space. Furthermore, some combustible materials during incineration are converted into heat or electricity, enabling energy reuse.

[0003] However, incineration technology also comes with significant shortcomings: the incineration process produces a large amount of smoke, exhaust gas, dioxins and other toxic substances. These emissions cause serious pollution to the atmospheric environment, affecting human health and the surrounding ecological environment, and the exhaust gas needs to be further purified; incineration requires a large amount of energy to maintain a high temperature environment, resulting in a waste of energy resources.

[0020] After medical waste is put into the disinfection chamber 1, quicklime is put into the disinfection chamber 1 through the conveying mechanism 4, and the medical waste and quicklime are crushed and mixed by the crushing stirrer 14. During the high-speed rotation and crushing process of the crushing stirrer 14, heat is generated in the disinfection chamber 1. Then water is injected into the disinfection chamber 1, and the water and quicklime undergo a hydration reaction and generate heat. The medical waste is disinfected by combining the heat generated by the crushing and hydration reactions, which greatly reduces energy consumption. In addition, the calcium hydroxide produced by the quicklime hydration reaction can also be used as a chemical disinfectant for further disinfection, which has a better disinfection effect, does not produce toxic gases such as dioxins, and can avoid secondary waste generation.
