Problems solved by technology

Especially after the outbreak of SARS, a large amount of medical waste was produced, but the lag of medical waste treatment facilities has brought many problems to the harmless treatment of waste and the prevention of secondary pollution
Now all countries in the world generally adopt incineration as the treatment method of medical waste, and the treatment method of this kind of garbage mainly adopts direct-fired incineration, which is dehydration and drying, pyrolysis gasifica

Embodiment Construction

[0019] The process of the present invention will be further described below in conjunction with the accompanying drawings and examples.

[0020] figure 1 The incinerator in is a vertical pyrolysis gasification incinerator. The specific process steps are: medical waste □ lifting feed into the pyrolysis gasification incinerator □ incineration □ flue gas treatment, the incineration steps also include the following process steps: Dehydration drying □ pyrolysis gasification □ combustion □ secondary combustion, flue gas treatment also includes flue gas settlement □ waste heat recovery □ flue gas desulfurization and dust removal process.

[0021] First, the automatic lifting feeding, the medical waste is sent to the feeding port through the closed transport vehicle, and the medical waste is sent into the incinerator by the automatic lifting feeding device. The transportation and feeding of the entire medical waste is carried out in a closed environment, and the operator does not com...

Abstract

The invention relates to a medicine garbage burning technology. The medicine garbage is transferred to the material casting entrance by sealed special transport vehicle and casting equally, quantificatioally into the burning furnace by automatic lifting material feeding device. And the process of dehydration and drying, pyrolysis and gasification, burning, second burning, smoke sedimentation, waste heat recovery and smoke dealing with would be taken. Thus, the content reduce quantity would reach 99%. The invention can effectively avoid the produce of poisonous substance.

Description

Technical field [0001] The invention relates to a medical waste treatment process, in particular to a medical waste incineration process. technical background [0002] Medical waste is infectious waste, which contains dozens or even thousands of times of germs than ordinary waste. It is called a "deadly killer". It is also listed as No. 1 hazardous waste in my country's "National List of Hazardous Wastes". Except for a few cities such as Guangzhou, Hangzhou, and Dalian, which implement centralized disposal and a small part of which are simply incinerated by hospitals, medical waste in most cities is mixed with domestic waste for disposal. Especially after the outbreak of SARS, a large amount of medical waste was produced, but the lag of medical waste treatment facilities has brought many problems to the harmless treatment of waste and the prevention of secondary pollution. Now all countries in the world generally adopt incineration as the treatment method of medical waste, ...
