Technical field
The present invention relates to a kind of pyrolytic reaction devices of medical waste, and in particular to a kind of heat for handling medical waste
Solve reaction unit.
Background technology
Medical waste is also known as clinical waste, refers to medical institutions in medical treatment, disease-prevention or healthcare and other correlated activations
What is generated has directly or indirectly infectious, toxicity and other harmfulness waste, specifically includes infectivity, pathologic, damage
Wound property, Drug, chemically waste.To medical waste if do not strengthened management, arbitrarily abandoning, it is allowed to be mixed into house refuse, scatters
Into people's living environment, air, water source, soil and animals and plants will be polluted, transmission is caused, seriously endanger the body of people
Heart health.Medical waste is a kind of catastrophe risk waste, and treatment of!medical waste problem has become the hot spot of whole world concern, China
《Dangerous garbage register》It is middle to be classified as No. 1 dangerous garbage.
Currently, frequently with treatment of!medical waste technology have sterilization method and high temperature incineration method.Sterilization method needs needle
Different sterilizing methods are selected different medical wastes, and sterilization effect limiting factor is more, due to the type of medical waste
Various and otherness is big, and it is therefore possible to be unable to reach best sterilization effect.And the volume and appearance of rubbish will not occur
It substantially change, directly abandons degradation difficulty, still pollute the environment.So the pretreatment before can be used for burning under general condition,
A kind of preposition processing means of medical waste can only be used as.Burning disposal is the chemical process of a deep oxidation, in thermal-flame
Under effect, the medical waste in burning facility converts it into residue and gas by drying, igniting, burning three phases, disease
Pathogenic microorganism and harmful substance are also effectively destroyed because of high temperature during the burning process, moreover it is possible to effectively realize volume reduction and loss of weight.But
It is that incendivity ingredient accounting is about 90% or so in medical waste, the rubbish for still having 10% or so is incombustible, therefore
There are problems that being not thorough the processing of medical waste, and different medical waste burning points is different, medical treatment is burned using burning method
When rubbish, required temperature is very high, and the heat generated in combustion process can not recycle, and cause energy loss.
Invention content
It is an object of the invention to：There is provided it is a kind of for handling the pyrolytic reaction device of medical waste, using having in rubbish
