In order to meet state environmental protection, The macro-control policy of energy saving and emission reduction, Meet the country’s solid waste reduction, recycling and resource recovery requirements, From the project’s economic benefits and the protection of arable land, conserve energy and improve the environment of social benefits, Companies decided to invest in annual processing capacity of 60,000 tons of flammable solid waste treatment project to conduct a feasibility study on carbonization.
Significance of project construction
Combustible garbage carbonizing treatment project is a combustible waste as raw materials, “High temperature pyrolysis, gas volatile, sulfur release carbon enrichment “process made” man-made carbon ” waste treatment technology.Garbage carbonizing technology combustible waste can be reduced in size by more than 95% than direct landfill will save more than 80%! Put an end to the waste disposal generally exists in stacking fermentation odor emissions, As well as secondary noxious liquid leakage to the atmosphere and groundwater pollution; By-product of garbage carbonizing process “artificial carbon” fixed carbon content is high (about 90%), About twice the coal (coal-fired fixed carbon content of 55%), With good flammability is a new advanced fuels, Simultaneously the partial carbonization of rubbish can be activated very scalable (can activate up to 75%)， Is the ideal material for adsorption of activated carbon.
The market situation
Survey: China’s medium and small cities continuously since the late 19th century the construction of more than 100 hectares of landfills more than 400 seats, Covers an area of tens of thousands of hectares of land, All day and smell the nostrils, Sewage overflows, Serious threat to residents living and production, therefore, badly need for landfill excavation, sifting garbage of different ingredients, and refusing harmless treatment and resource utilization. If garbage carbonizing treatment technology which about 2 million cubic meters of combustible waste harmless after carbonization treatment of about 1 million tons, only accounted for more than 70 hectares of conservation, economic and social benefits can be gauged; this example serves to illustrate the garbage carbonization treatment technology of huge market demand, economic benefits, social benefits are the market structure adjustment in China highlighted another emerging Sun occurs during project.
Production sites and site selection
Production sites according to local conditions, make full use of abundant, roads built where convenient, reducing investment in the project.
Raw material requirements
Raw materials used in the production of urban refuse and industrial paper and other combustible organic materials.
1．Waste inorganic constituents of less than or equal to 5%.
2．Lime: CaO content greater than 40%.
Major sources of raw materials, quality and price standards
Combustible garbage: from the transit of waste transfer station or landfill digging. Used cars shipped to the factory, the factory price of 0.
Lime: the use of nearby factories to produce raw lime powder. Used cars shipped to the refinery, the factory price of 500 Yuan/ton.
Processing capacity
Processing products: combustion of municipal solid waste treatment capacity: 60,000 tons a year.
Treatment standards
After processing raw materials and reduced in size by more than 90%, flue gas emissions reached EU2000/76/EC or GB13271-2001 standards, the treated “man-made carbon” fixed carbon content reaches more than 75%.
main technical parameters
1．Combustible waste composition and moisture control
Waste water: 60% inorganic content: 5%
Litter size: maximum length 50 mm, thickness 15 mm
2．Baking temperature: 150 degrees Celsius
Drying time: 10-25 min
3．Carbonizing temperature: 200-800 degree Celsius
Carbide time: 10-25 min
4．Product temperature: 25-40 degree

The General plan and transportation
This machine adopts the design of double layer and multi passage. It is mainly composed of drier, carbonizing machine and other auxiliary equipments. Double-layer design make the lower part of the machine contact the hot air as much as possible, this design is helpful to raise the heat utilization efficiency from the beginning. The lower layer equipments utilize residue heat in carbonizing gas to flash steam the materials. This is the second stage to raise the utilization efficiency of heat. The optimized and concentration multi-pipe design of hot exhaust gas (generated from gasifier or hot blast heater) recycling pipe, carbonizing and fission heat collecting pipe, flash steaming steam collecting pipe, combustion emission collecting pipe can raise the heat utilization efficiency in the third time. After three time of optimized usage of heat, the temperature of the emission gas is below 100 centigrade. Under the inspection of related institutes, the heat use ratio of our equipment is over 85%. Our equipment is called perfect flax stem carbonizing equipment by Erie flax factory in Xinjiang province.
Environmental protection
1．Implementation of this project’s environmental standards
(1) the industrial enterprise factory boundary noise standards GB12348-90 “ⅱ” such criteria;
(2) the GB9878-96 of integrated wastewater discharge standard table 3 “second-level” standard;
(3) the atmospheric pollutant emission standard of boilers GB13271-2001 table 1 “second-level” standard.
Energy saving effect and evaluation of the project
Combustible garbage carbonization process energy consumption compared with the incinerator and burned trash, energy saving rate below 120% if compared with traditional landfill, saves 95% of disputes over land. Combustible garbage carbonization process is fully implemented, “reduction”, “harmless” and “resources”. Combination of these, combustible garbage carbonization treatment compares with any kind of approach are the most ideal, one of the greenest, most energy-efficient, most scientific approach, average energy efficiency of more than 110%.
