Description
Technical field
The present invention relates to the innoxious comprehensive utilization of resources of cover medical waste system, this system belongs to the dangerous solid waste process field of environmental protection industry.
Background technology
Medical waste is the solid waste that medical institutions, physiological and pathological research institution etc. produce, mainly comprise excision thing, surgical dressing (gauze, absorbent cotton etc.), disposable transfusion device, disposable syringe, blood bag, have the treatment refuse of body fluid, epidemic victim's blood, phlegm, secretion, vomitus, clinical laboratory, discarded sample, the laboratory animal corpse the like waste of pathology department.Medical waste contains a large amount of viruses, bacterium and chemical agent, is a kind of to the great material of environmental hazard.It has been listed in the Basel Convention of control hazardous waste transboundary movement and disposal thereof in the world, the Chinese government also listed it in 1998 " national hazardous waste register ".Because medical waste has features such as total space pollution, acute infection and latent infection, its harmfulness is very big.If manage badly, deal with improperly and will bring out great environmental pollution accident, serious harm human beings'health.
Along with improving constantly of living standard, people pay attention to the quality of life quality and living environment more, and the processing of medical waste has been subjected to people's great attention! The most frequently used processing method of medical waste has:
Landfill disposal: the medical waste landfill not only takies a large amount of soils, also be difficult to accomplish innoxious, volume reduction ratio is littler, the percolate of medical waste landfill contains a large amount of viruses, bacterium and chemical agent, meeting water-supply source and soil environment have been brought long-term harm, the pernicious gases such as biogas that landfill produces bring pollution etc. to air, these insoluble problems, and serious threat is to peripheral resident's health.
Burning disposal: medical waste is through high temperature incineration, and poisonous and harmful substance is thoroughly decomposed and is transformed into inanimate matter, and it is remarkable to burn back solid waste minimizing effect, is processing method comparatively completely.
Application number is 200820212569.4 utility model patent, introduced a cover pyrolytic incineration furnace apparatus, this equipment adopts the mode that pyrolysis is fired again to carry out burning disposal, medical waste is decomposed under the indoor high temperature anaerobic condition of a combustion, gasification, short chain gas after the decomposition enters dual firing chamber and carries out purification of combustion, realizes harmless treatment.
The patent No. is the utility model patent of 02232562.X, is earlier medical waste to be fermented in negative pressure cabin, and it is combustion-supporting that the biogas of generation is sent into incinerator, and the medical waste after the fermentation process realizes harmless treatment through Roarykiln and twice burning of vertical incinerator.
Also useful plasma technology burns the equipment of medical waste, and the temperature of plasma can realize harmless treatment with medical waste moment high-temperature gasification, no residue about 10,000 ℃.But the complicated investment of plasma processing is very big, the power consumption and the expense of equipment operation are all very high, and the equipment operation maintenance specification requirement is higher, and the flue gas after the burning still need be handled.
The burning disposal of medical waste has been burnt it with the medical plastic of high value etc., causes the huge waste of resource, burns and also will consume a large amount of auxiliary fuels, is not inconsistent the requirement with sustainable development.Simultaneously, the pollutants such as dioxin that produce in the medical waste combustion process bring serious harm to environment and human health; Burning the flying dust and the slag that produce is that danger wastes still needs security landfill to handle equally, and these have all seriously limited the development of burning disposal.
Disinfect: the harm of medical waste is that it contains a large amount of viruses, bacterium and chemical agent, adopts sterilization methods such as high temperature and high pressure steam, chemical agent, microwave, radiation, can kill microorganisms such as virus, bacterium:
The patent No. is 200410035466.1 patent of invention, it is a kind of pulsation replacing process that adopts the sterilization of steam increasing temperature and pressure, vacuumizes drying, to method and the equipment thereof that medical waste is carried out harmless treatment, this method sterilization completely, does not produce secondary pollutions such as flue gas.
Application number is 200720043414.8 patent of invention, is to adopt to clear up still feeding high temperature and high pressure steam, and medical waste is carried out sterilization treatment.
The patent No. is 200410026158.2 patent of invention, is the effect that utilizes microwave, and medical waste is depolymerized, and complicated organic compound is changed into the process of nontoxic simple compounds.
Application number is 200810113500.0 patent of invention, is to utilize radiation sterilization ground method, the medical waste after pulverizing is carried out radiation sterilization handle.
Above-mentioned medical waste disinfection treatment method is widely used, can thoroughly kill wherein bacterium and virus, fundamentally solves innoxious problem.But disinfect the final disposal that is not medical waste.
Turning sludge into fuel is handled: because the content of plastics, toilet paper, staple is very big in the medical waste, calorific value is higher, can be used to make fuel, carries out recovery of resources with the form of heat energy.Comparatively the Cheng Shu method of utilizing has: one is that pyrolysis gas is combustion gas after purified treatment with the gasification of medical waste low temperature pyrogenation, can be used for the burning heating; This method still need be handled the lime-ash after the pyrolysis.They are two years old, be with after the medical waste harmless treatment, through extrusion dehydration, pulverizing, oven dry, add additives (also can mix an amount of sawdust or powder of straw according to actual needs again) such as desulfurization, heavy metal passivation, stir after the special process device fabrication goes out efficiency of combustion height, free of contamination RDF (garbage derivatived fuel), RDF can be used as boiler or other fuel with hot equipment.
If can earlier recoverable materials such as medical plastic, paper material be sorted out and recycle, more remaining combustible is carried out just science, reasonable, perfect more of heat energy recycle.
The processing method of above-mentioned medical waste and relevant technical equipment system be imperfection all, can only be a part in the complete innoxious comprehensive utilization of resources of the medical waste system.
Recycling treatment: though medical waste is harmful discarded object, but medical flexible plastics such as medical duroplasts such as disposable syringe wherein, matter holding box, dish and one-time infusion tube, infusion bag, blood bag, waste fluid bag all are that the high-quality non-toxic plastic is made, these class article have very high recycling and are worth, through just fabrication cycles utilization once more after innoxious, the purified treatment; Packing case wherein etc. contains the stationery article, also can reclaim narrow resources paper pulp by making beating; Common plastics wherein also can be recycled through after innoxious, the purified treatment; Also have glass, metal etc. to have more the value of recycling; Combustibles such as remaining foreign material such as cotton goods, wet pad can be used for producing RDF and reclaim heat energy.As seen, medical waste can all be recycled as resource.
If will carry out the recycling of resource to medical waste, the innoxious comprehensive utilization of resources of complete medical waste system should comprise: harmless treatment equipment, perfect screening installation and advanced three major parts of recycling equipment are formed reliably.This system with the medical waste harmless treatment after, effectively classify again, and sorted each component carried out the recycling of high value, only in this way can realize whole recyclings of medical waste.In the removal process of resource, the medical waste treatment system also should be considered the problem of energy savings and environmental protection.
The content of invention
