Process for burning medical refuse

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, ...

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 gasification, volatile gas evaporation and combustion and fixed carbon The several stages of medical waste incineration such as combustion are all carried out in the same incineration equipment. Although this technology has been developed for more than 100 years, it has the disadvantages of large gas supply, high dust content in the flue gas, and high dust content in the flue gas. High control requirements, complex flue gas treatment system, high investment and operating costs, etc.
