Come more serious, the especially development of hyundai electronicses information technology, medical Chemical Engineering Technology, cause the generation of many hazardous wastes.Together
When with the quickening of Urbanization in China, urban population has a very big development, therefore is produced as all kinds of wastes of city public hazards
Raw amount is growing day by day.Either industrially developed country, or developing country, all suffer from dangerous waste disposal problem.
According to《The big or middle MSW pollution environment preventing and treating annual report in the whole nation in 2015》Statistics, 2014,244 big,
Middle urban industry hazardous waste yield up to 2436.7 ten thousand tons, wherein, 1431.0 ten thousand tons of volume of comprehensive utilization, disposal amount 889.5 ten thousand
Ton, 138.0 ten thousand tons of storage capacity.Industrial dangerous waste volume of comprehensive utilization is accounted for using disposing the 58.2% of total amount, and disposal, storage are distinguished
Accounting 36.2% and 5.6%, it is the main path for handling industrial dangerous waste to effectively utilize and dispose, and urban is to history heap
The hazardous waste deposited has carried out effective utilization and disposal.The province that industrial dangerous waste yield comes front three is Shandong, lake
South, Jiangsu.2014,244 big or middle 62.2 ten thousand tons of Urban Medical Wastes yield, disposal measured 60.7 ten thousand tons, most of city
Medical waste treatment rate all reached 100%.The province that clinical waste yield comes front three is Guangdong, Zhejiang, Henan.Disappear
Except the pollution of hazardous waste, its innoxious, minimizing and recycling are realized, has become the significant problem that China must solve.
The portion that Zhejiang various regions the departments concerned is renovated according to Zhejiang Provincial Commission, provincial government on construction of ecological province and environmental pollution
Administration, the harmlessness disposing work of sludge, Polluted Soil and industrial dangerous waste is deepened constantly, strengthen sludge, Polluted Soil and industry danger energetically
The scientific research and popularization and application of useless disposal technology, accelerate to promote sludge, Polluted Soil and industrial dangerous waste harmlessness disposing facility to build
If.And according to《The new 2 years action schemes of 811 environmental protection》General plan, with " minimizing, stabilisation, recycling and harmless
Change " it is target, using mechanism and technological innovation as means, attached most importance to harmlessness disposing Facilities Construction, adhere to overall planning, substep
Implement, suit measures to local conditions, guidance to different types of areas, key breakthrough, with a band and, take effective measures, conscientiously accelerate promote sewage sludge harmlessness
Disposing task.
It is that numerous disposal options realize that minimizing, innoxious and recycling are preferable using cement kiln synergic processing hazardous waste
One kind.Ended for the end of the year 2013, China be completed, build in and it is proposed set cement kiln synergic processing hazardous waste enterprise sum
More than 200, wherein about 25% enterprise is related to cooperative disposal hazardous waste, national cement kiln cooperative disposal hazardous waste it is total
The t/d of ability 20,000,2103, the total amount of China's quality coal in cement kiln systems disposal hazardous waste reached 55.9 ten thousand t.

Free-falling behind summit, into charging aperture, carry out follow-up disposal process.It is between each equipment of lock feeding device and equal with cement kiln
It is attached using pipeline, the flame retardant coating made of exotic material is provided with pipeline.
The connection of pipeline and smoke-box, design angle are less than 35 degree, the i.e. angle of connecting pipe outer wall and smoke-box outer wall, are less than
35 degree.This design can make it is broken after waste packing articles material hurtle down into smoke-box, will not the hardened accumulation on duct wall, just
In the incineration disposal of material.
D, incineration disposal
Waste packing articles material after broken passes through smoke-box（Or dore furnace）Into cement high temperature area, 800-1000 DEG C of temperature, stop
The time is stayed in more than 4s, is more than 14s in the total system residence time, while is oxidizing atmosphere in cement kiln, waste packing articles
Organic principle moment is broken down into vapor and carbon dioxide, by being discharged into air after dust cleaning, the composition that can not decompose with
Cement raw material enters rotary kiln together, and heavy metal therein is cured to cement products, obtains waste packing articles thoroughly harmless
Change is handled.
Specifically, reference picture 1-2, waste packing articles material is conveyed into factory, by trolley hoist hang 11 by partial material transport to
Middle deck is stacked, and partial material is directly lifted to the top of shredder 2, and for manual control slowly after decentralization, shredder 2 carries out work
Make, waste packing articles material is subjected to cutting and torn up, naturally it is also possible to is transported to waste packing articles material by infeed belt conveyor 12
The top of shredder 2；By the material that shredder 2 is disposed by outfeed belt conveyor 3, Pneumatic reverse turning bed air valve 4, gas are sent to
The packaging bag lock feeding system that dynamic slide valve 5 forms, pipeline 6 made of the bottom seamless steel pipe of Pneumatic gate valve 5 are directly same
Cement kiln smoke-box connects, and the inwall of pipeline 6 has refractory material, and the angle of inclination that pipeline 6 is connected with cement kiln smoke-box is less than 35 degree, i.e.,
α is less than 35 ° in figure.By the operation principle of Pneumatic reverse turning bed air valve 4 and Pneumatic gate valve 5, material is constantly added by pipeline 6
Into smoke-box, high temperature incineration disposal is carried out.Reach innoxious, the disposal of resources of waste packing articles material.
Above-mentioned embodiment is used for illustrating the utility model, rather than the utility model is limited,
Spirit of the present utility model and any modifications and changes in scope of the claims, made to the utility model, all fall
Enter the scope of protection of the utility model.
