Description
Technical field
The present invention relates to environment protection treatment fields, more particularly, to a kind of quick anhydration system of low energy consumption wet stock and method.
Background technique
In environmentally friendly recycling field, material drying and other treatment is a kind of conventional means, and the material of processing generally includes biomass
And sludge.
With growing to even greater heights for oil crisis and reduction of greenhouse gas discharge cry, finding alternative clean energy resource just becomes neutralizing
The optimal strategy of energy crisis and greenhouse effects.Since biomass energy is as a kind of chemical state energy, can not only generate electricity, heat supply,
And liquid fuel and biobased products can also be converted into, be uniquely can extensive substitute fossil fuels the energy, it is main flourishing
The technical specialist and policymaker of country pay much attention to the exploitation of Biomass Industry.In recent years, it is produced along with for biomass energy
Industry is innovated and the fierce controversy such as " the Che Renzheng grain " of generation, " humanitarian crisis ", " environmental problem ", the innovation of world's bio-energy industry
Start to show new trend and feature.
Biomass energy refers to organic wastes such as agricultural and using the energy-source plant that marginal land is planted for original
Material, using starch crops grease as adjusting, the renewable and clean energy resource of production and related chemical products can be from crops straw
The agriculture and forestry products such as stalk, sugarcane, corn, beet, cassava, potato, cottonseed, rape and woods shrub, and Animal husbandry production are discarded
The energy extracted in the organic wastes such as gas object, domestic waste is abandoned in object, industry, is a kind of environment amenable renewable money
Source, such as alcohol fuel, biodiesel, biogas.And energy crop is produced and plants thus, product is to produce biomass
The industry of the energy is then Biomass Industry, or is energy agriculture.Development of the Biomass Industry in recent years in China is agricultural
One concrete embodiment of new function (biomass energy is provided), while it being also sent to the great expectations of " modern agriculture new growth point ",
Biomass Industry Development of China has become the important measure that China accelerates Construction of Modern Agriculture, develops Rural Circulation Economy.
Biomass is directly burnt: directly burning is broadly divided into cooking stove burning, boiler combustion, waste incineration and compact formed
4 kinds of situations of fuel combustion.Many sugar refinery of southern area are generated electricity using bagasse, and Guangdong, two province of Guangxi share small generator
Group 380, total installation of generating capacity is up to 800 megawatts, and there are also such power plants in Yunnan Province.Bagasse power plant is general only to squeeze Ji Yun
Row.China introduces European Technical, and the biomass such as construction stalk, husk are directly burnt or one coal of biomass is mixed and burned the work to generate electricity
Industry Applied D emonstration engineering, the sixth of the twelve Earthly Branches finished item feasibility study works at present.
Biomass solid shaping fuel is former of making a gift to someone after crushing the agriculture and forestry organic waste materials such as crop material, rice husk, sawdust
In tool, under external force, it is compressed into the shape of needs.Then, make fuel directly to burn, can also be further processed, form life
Object charcoal.Currently, the biomass solid shaping machine that China researches and develops out has also been applied to production.The compact formed combustion of production
Material, also the sixth of the twelve Earthly Branches is applied to heating and miniature boiler.After measured, the pollutant of this kind of fuel draining is lower than coal, is a kind of efficient, clean
Net renewable energy.Curing molding method has production technology, equipment simple compared with other methods production biomass energy,
It is easily operated, production equipment to adaptable and curing molding the fuel of various raw materials convenient for storing (can store for a long time and
Long-distance transport) and the features such as be easily achieved industrialization production and large-scale use.In addition, to existing combustion apparatus, including boiler,
Cooking stove etc., being simply transformed can be used.Shaped fuel is easy to use, and especially to northern China extremely frigid zones, a heatable brick bed stove is
Winter main heating form, there is traditional use habit in vast rural area, and shaped fuel is also easy to be received by common people.
Biomass source is extensive, may be from timber, agricultural by product, animal wastes, paper pulp and paper etc., and original
The biological material of form is generally rich in moisture and particle is larger, is not suitable for directly applying, therefore drying and other treatment is to improve it
The necessary means of service efficiency.
" three wastes " disposing task management is always the most important thing of Environmental protection management work, the place of waste water,waste gas and industrial residue
Set management just year by year to rationalization, standardization and scientific transformation, wherein the management of waste residue has been also raised to unprecedented
Height.The disposition of sewage farm excess sludge is that current environment conservative management works the outstanding problem that faces, at each sewage
Reason field all suffers from how to dispose leads to the problem of a large amount of excess sludges daily, since its yield is big, transport disposal is difficult, place
The reasons such as costly are set, are the emphasis of enterprise and environmental protection department at different levels work.
It there is no appropriate compromise method of disposal at present in China, handled in the sludge of industrial wastewater in addition and contain certain proportion
Heavy metal substance and the poisonous and harmful substances such as hydro carbons, oils, belong to hazardous waste classification, long-term arbitrarily to stack, all kinds of nocuousness
Substance can be concentrated in the soil or occur physical-chemical reaction, be likely to result in soil soil property and pollute hardened, groundwater quality pollution
Equal secondary pollutions.
Therefore, sludge treatment problem has become most of sewage farm urgent problems to be solved, and whether sludge treatment
