Description
Technical field
The invention belongs to Waste Disposal Technology field, a kind of processing system more particularly, to Biohazard Waste and its make
Use technique.
Background technology
Hospital produces substantial amounts of different types of discarded object, in addition, health care discarded object can also be by other as urgent
Medical treatment and nursing service, blood transfusion or the sources such as center, laboratory, zooscopy, blood bank of dialysing produce.Caused by most of discarded object
It is no risk, it is the same that the discarded object of general health care is also similar to household waste.It is essentially from health care
Caused when the administration of mechanism and management and maintenance maintenance, remaining health care discarded object is considered as dangerous, may be used also
It can produce various communicable health problem.Dangerous Biohazard Waste is typically to carry out burning disposal.
Temperature of the discarded object when incinerator is burned is at a relatively high, if medical refuse incinerator is not by complicated first
It will discharge substantial amounts of various poisonous, harmful pollutants during the tail gas treatment device processing entered, including dioxin and furans, again
Metal (such as lead, mercury and cadmium), pellet, sour gas (hydrogen chloride, sulfur dioxide), carbon monoxide and nitrogen oxides
(composition of haze) etc..These emissions bring serious adverse consequences to the safety of operator, publilc health and environment.Institute
Have to just be disposed off before atmosphere is released to this gas, therefore may result in the volume of incinerator operating cost
Outer increase.
Incinerator also can always suffer from unnecessary thermal effect loss.All discarded objects are destroyed in order to reach a high temperature
Purpose, incinerator, which will typically consume more multiple fuel, can just be burned to higher temperature.Dangerous medical waste is due to its own
Infectiousness, general correct way is to reduce artificial operating of contacts as far as possible.So packs of medical wastes will be by
It is sent directly into incinerator to burn, but the difference for causing heat demand has been carried out into quilt because the volume of every bag waste material is different from density
Burn.The final result of such a situation is increase fuel cost to provide higher temperature to achieve the goal.
There is landfill communicable Biohazard Waste to considerably increase human health and the risk of environmental pollution.It is once discarded
Thing is agitated or covered in any way inappropriate, it will further risk occurs.Therefore land-fill method is not one
The Biohazard Waste processing mode planted, is not also allowed by thumping majority government.Such as want to take precautions against these risks, while work as and fill out
When to bury field be also unique available selection, then effective method is exactly just to destroy or remove medical waste in original place
After the infectiousness of thing, just it is transferred to landfill yard and disposes.
The content of the invention
In view of this, the present invention is directed to propose the processing system of a kind of Biohazard Waste and its using technique, can accomplish compared with
Handled under low temperature conditionss in the minimum operating process of harm is reached, completely solve conventional incineration stove and cured in processing
The atmosphere pollution such as caused pollution source such as dioxin during treatment discarded object, so as to realize that more preferable fuel uses effect
Rate and environmental protection efficiency.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：
A kind of processing system of Biohazard Waste, successively including pretreatment unit, carbonizing plant, waste gas cracker and
Exhaust gas processing device；
The pretreatment unit is connected by helix transporting device with the feed cap of carbonizing plant；
