Description
Technical field
The invention belongs to environmentally friendly technical field of new energies, be related to sludge garbage prepare environmentally-friebiomass biomass composite fuel and its
Preparation method.
Background technology
With the quickening of China's rapid economic development and urbanization paces, the yield of municipal sludge rubbish increases therewith, by
Containing harmful substances such as heavy metal and pathogenic microorganisms in sludge garbage, such as process mishandling, can be brought seriously to environment
Secondary pollution, while taking substantial amounts of land resource.It is reported that the present situation of the current sludge waste disposal of China is more than 70%
Throw aside, nearly 20% landfill, next to that carrying out that compost is agricultural or plant species plantation is used less than 10%, sludge anhydration burning is carried out on a small quantity.
Some drawbacks that traditional sludge treatment technology is present, with certain limitation, as country is to the mark of specific resistance to filtration technology
Quasi- more and more higher, conventional art is not adapting to the requirement of social development.It is mainly manifested in the following aspects.
The landfill of sludge garbage, need to take the place of large area；Ground need to do Anti-seeping technology in order to avoid polluted underground water, treatment
It is improper, secondary pollution can be caused；Not reusable edible.The burning of sludge garbage, though can be greatly reduced sludge volume and
Weight, has accomplished minimizing；Processing speed is fast, is not required to long-term accumulation and storage；Can on-site incineration, be not required to long-distance transportation, save
About freight charges；Can recover energy for generating and heat supply；But it is that incinerator invests huge, equipment operation to burn fatal shortcoming
It is costly；Device is complicated, and burning process is not easily controlled, and produces pollutant emission；The insufficient, firepower that burns is not prosperous enough, temperature
The toxic contaminants material such as bioxin, incinerator burning process may be produced to produce poisonous position to be difficult to control to when not high enough,
Need to carry out flue gas specially treated, therefore limit it to use and develop.Sludge composting and Land_use change, mainly by sludge
For compost it is agricultural, for the fertilising of gardening greening vegetation, betterment of land for discarding the ground such as mining site etc.；Compost is mainly used
The effect of microorganism, by unstable organic matter degradation, is converted into relatively stable organic matter, and drop volatile matter content
It is low, reduce the generation of foul smell.Containing nutrients such as abundant organic matters and N/P/K and beneficial to the micro of plant growth in sludge
Element etc., but also containing sludge containing a large amount of pathogen, parasite, Polychlorinated biphenyls and poisonous and harmful substance, do not fired by high temperature
Burn and process and directly applying to agricultural can cause the secondary pollution of soil and water body；Therefore composting process is not sufficient to ensure that security.
Though current China has and prepares fuel source to municipal sludge and utilize technical method, at sludge dewatering minimizing
Reason difficulty is larger, relatively costly so that made fuel price is higher, market is limited etc.；And fail effectively using containing in sludge
Have substantial amounts of organic composition and using in material, especially municipal sludge containing substantial amounts of organic composition, such as vegetable oil,
Animal tallow etc., with fuel value higher, shows according to test, sludge caloric value in 2300 kilocalories or so, intimate lignite etc.
