Problems solved by technology

[0005] 1) Dozens or even hundreds of metal "fly ash" and acid gases are released during the incineration process, seriously affecting human health
[0006] 2) Landfilling of medical waste requires a large amount of land, resulting in waste of land resources
Due to the high organic content of medical waste, which is difficult to decompose, it will inevitably cause secondary pollution to the environment, land and groundwater sources, and pose a hazard to human health.
[0007] 3) During the transportation process of transporting medical waste from hospitals and other medical institutions to centralized treatment places, germs and viruses will continue to spread on the way, bringing potential risks of secondary pollution to the society
Incineration and burial will waste a large amount of plastic, metal and other recyclable materials, wasting natural resources
[0009] One of the methods commonly used to deal with medical waste is mainly to sterilize through one-time high-temperature steam, but only one steam disinfection often cannot completely kill the virus

Embodiment Construction

[0018] In the present invention, a sealed container is evacuated and then injected with high-temperature steam for several minutes, then evacuated and then injected with high-temperature steam, repeated several times, and finally disinfectant is injected to complete the disinfection process.

[0019] The device used in the present invention is as figure 1 As shown, the sterilization tank 1 is a sealed container, and the sealed container has an openable cover body 2 . An air extraction port 3, a steam inlet 4 and a disinfectant inlet 9 are also provided on the sealed container body, and the air extraction port 3 is connected to an air extraction pump 5 for vacuumizing the disinfection tank 1; the steam inlet 4 is connected to a steam generator 7. The steam generator 7 is used to generate and provide high-temperature steam into the disinfection tank 1 , and the disinfection solution inlet 9 is connected to a disinfection solution tank 11 .

[0020] Because the disinfection meth...

Abstract

The invention provides a disinfecting method for medical waste, which comprises the steps of: evacuating a sealed container and then injecting above 135 DEG C steam for a period of time, then evacuating and then injecting above 135 DEG C steam, repeating the operation for several times, and finally injecting a disinfecting solution to complete the disinfecting process. Under a vacuum state, virus can be more thoroughly killed by adopting high-temperature steam disinfection for many times and matching with the disinfecting solution.

Description

technical field [0001] The invention relates to a disinfection method of medical waste. Background technique [0002] Medical waste (also known as medical waste) has the characteristics of full-space pollution, acute infection and latent pollution, and the harmfulness of microorganisms contained in it is dozens, hundreds or even thousands of times that of ordinary domestic waste. Improper treatment will become the source of nosocomial infection and social environmental pollution, and more seriously, it can become the source of epidemics. [0003] Medical waste contains bacteria, viruses and harmful substances to varying degrees. Moreover, the organic matter in the waste not only breeds mosquitoes and flies to cause the spread of diseases, but also releases malodorous gases such as ammonia (NH3) and hydrogen sulfide (H2S) during decomposition, generating a variety of harmful substances, polluting the atmosphere, and endangering human health; It is also the main cause of cro...
