Description
Technical field:
The utility model relates to a kind of field of Environment Protection, relates in particular to a kind of dangerous waste and medical waste incinerator complexes.
Background technology:
Hospital wastes refer to the refuse that all needs of hospital abandon, can not recycle, and comprise and biological and inanimate also comprise house refuse.The refuse producing in the process of the activities such as clinical waste refers to patient and diagnoses, treats, nursing.
Different from house refuse, medical waste thing contains a large amount of bacteriums, virus and chemical agent, there is extremely strong infectiousness, bio-toxicity and corrosivity, unprocessed or process halfway medical waste and stack arbitrarily, very easily cause the pollution to water body, soil and air, human body is produced to direct or indirect harm, also may become the source of pestilence.
Medical waste is a class catastrophe risk refuse, medical waste is processed problem has become the focus that the whole world is paid close attention to, and China is classified as dangerous garbage No. 1 in < < dangerous garbage register > >.Reinforcement is to the normalized management of medical waste and harmless treatment, is in protection of the environment or is all being extremely important aspect prevention from suffering from the diseases and control.
Chemistry refuse refer to there is toxicity, the discarded chemical substance of corrosivity, inflammable and explosive property is as the chemical reagent of medical image chamber, laboratory abandoned, the chemosterilants such as discarded Peracetic acid, glutaraldehyde, discarded mercury sphygmomanometer, mercury thermometer etc.
Dangerous waste and medical waste not only has potentiality and the chronicity of Ordinary solid waste environmental pollution, but also have inflammable, explosive, poisonous, harmful, burn into infection etc., is harmfulness, and harm consequence has cumulative bad, hysteresis quality and chronicity.At present existing multiple heat treatment technics can be for the treatment of the useless refuse of danger, but what the most generally adopt so far is high temperature incineration method.
Domestic dangerous waste incineration engineering ground zero, with European and American developed countries hazardous Waste Incineration engineering operations decades experience, technique choose with operative norm on have big gap.China's < < hazardous waste centrally disposes engineering construction technical specification > > HT/T176-2005 and issues and implement, it is the technical specification that industry has rigid constraint power, under standard instructs, successively built up successively province and district district dangerous waste incineration in recent years and centrally disposed engineering, the main technological process adopting as shown in Figure 3.
Such technique is processed by all means, regardless of the way of environmental consequence, is compared than the project of burning before, has had essential difference, becomes environmental protection project truly.But due to process detail, design level, operation management level, comprise many-sided reasons such as scale of investment, environmental protection tests dynamics, all there are a lot of weak points in a lot of projects, cannot reach set and comprehensive environmental protection tests requirement, although some project is gone into operation the several years, cannot pass through environmental protection inspection and acceptance always.These deficiencies are embodied in following aspects:
1) dangerous waste incineration technique adopts rotary kiln and dual firing chamber's combustion mode conventionally, often because discarded object kind changes frequent, cause clean combustion to be difficult to tissue, easily tempering, detonation, leak out, furnace temperature is fluctuated unstable, and the time of staying is inadequate, easily coking, over-emitting black exhaust, refractory material is short service time, and slag conglomeration, the phosphorus content phenomenon that exceeds standard becomes normality;
2) flue gas treatment effeciency is low, especially discharging dioxin value in flue gas exceeds standard, owing to affected by clean combustion technology and harmful substance firing efficiency, in addition prevent that the chilling that synthesizes again and the absorption link of activated carbon from not reaching specification requirement, greatly how far dioxin value surpasses the emission limit set 0.5TEQng/m of dioxin country
3, with standard 0.1 TEQng/m of European Union
3differ greatly especially;
3) automatic control level is low, and operating personnel's quantity is many, and labour intensity is large;
4) without foul smell, collect and process, operating environment is poor, and work personnel are vulnerable to harm;
5), because the reasons such as disintegrating machine spark, tempering and kiln hood string wind easily cause fire and personal safety accident, the garbage storing hole situation of catching fire takes place frequently.
6) hazardous waste compatibility is unreasonable, and calorific value is unstable, need to supplement auxiliary fuel, add many reasons such as equipment failure rate is high, and continuous operating time is short, so integrated operation cost is high; For reducing costs, operator can reduce the consumption that flue gas is processed various medicaments again, causes the not up to standard of exhaust emissions.So vicious circle, causes the environmentally hazardous situation of environmental protection project;
7) steam utilizes after producing nowhere, and energy waste situation is serious.
