Abstract
The invention relates to a novel method for comprehensive treatment of municipal solid wastes, comprising the following steps: separating different components in the municipal solid wastes by the procedures of preceding separation, water separation and wind separation, wherein bricks, tiles and stones are made into building materials, and plastics are granulated; and degrading and reducing organic matters and sludge, wherein the degraded organic matters are made into fertilizers or RDF. The invention fully conforms to the waste harmlessness, reduction and reclamation principle.
Description
Technical field
The invention belongs to the environmental protection field, particularly a kind of new method of Urban Domestic Waste Comprehensive Treatment.
Background technology
China's domestic waste output is huge at present, and treating capacity does not catch up with far away.The refuse landfill in present many cities overload operation, there are problems such as occupation of land is big, processing speed is slow, percolate processing difficulty in the mode disposal of refuse with landfill simultaneously.The fertilizer that composting process is processed is difficult to accepted by market because fertilizer efficiency is not good.Directly burning is the most effective decrement mode, but the domestic waste moisture content of China is higher, directly burns very difficulty, and easy generation of secondary pollution, and environment is produced very big threat.All there are many drawbacks in a certain method disposal of refuse of simple dependence.The present invention provides a kind of method of comprehensive garbage disposal, to overcome the deficiency that above technology exists.
Summary of the invention
Technical problem to be solved by this invention is: a kind of new method of Urban Domestic Waste Comprehensive Treatment is provided, to overcome the deficiency that exists on the conventional garbage treatment technology, for garbage disposal provides a kind of new way.
Technology contents of the present invention:
A kind of new method of Urban Domestic Waste Comprehensive Treatment is characterized in that: the steps include:
(1) preceding sorting
Domestic waste sorts out big part combustible through preceding sorting, makes RDF, and residue gets into the wet concentration device.
(2) wet concentration
Rubbish is after the wet concentration apparatus processes, and dregs forms mud in water, and brick and tile, stone and separating organic matters come.Mud input degraded device processes, brick and tile, stone are made building materials again through fragmentation.
(3) selection by winnowing
The organic matter that wet concentration goes out is isolated plastics and organic matter through selection by winnowing, and plastics are wherein processed plastic grain and sold, the organic degradative reduction equipment that gets into.
(4) degradative reduction
The mud input degraded equipment that organic matter that selection by winnowing is gone out and wet concentration produce; Add catalyst (sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid or in controlling catalyst at least a); Feed steam, make pressure in 0.6MPa～1.5MPa, temperature in 160～200 ℃ of scopes, carry out the reaction of 1h～3h.
(5) Separation of Solid and Liquid
After degradative reduction finishes, discharge excess liquid in the degraded equipment, handle through multiple-effect evaporation.
(6) spray quick-fried discharge
Solid material sprays quick-fried discharge in the presence of certain pressure, part moisture vapors away with steam, and the material water ratio of this moment is about 40%.Through extrusion dehydration, material water ratio can be reduced to below 30% again.Through the rubbish that degradative reduction is handled, can be used for making fertilizer, also can process RDF.
Effect of the present invention: through degradative reduction, most of macromolecular substances is degraded to small-molecule substance, has destroyed the structure of original organic matter, and constitution water is wherein also separated thereupon, changes free water into, and rubbish is dewatered more easily; Behind the degradative reduction, organic matter reaches stable state, is difficult for producing foul smell, is easy to storage.
Description of drawings
Accompanying drawing 1 is the process flow chart of this technology.
The specific embodiment
The present invention relates to dewatering organic in a kind of domestic waste, combine instance that its practical implementation step is described at present.
(1) preceding sorting
Domestic waste sorts out big part combustible through preceding sorting, makes RDF, and residue gets into the wet concentration device.
(2) wet concentration
Rubbish is after the wet concentration apparatus processes, and dregs forms mud in water, and brick and tile, stone and separating organic matters come.Mud input degraded device processes, brick and tile, stone are made building materials again through fragmentation.
(3) selection by winnowing
The organic matter that wet concentration goes out is isolated plastics and organic matter through selection by winnowing, and plastics are wherein processed plastic grain and sold, the organic degradative reduction equipment that gets into.
(4) degradative reduction
The mud input degraded equipment that organic matter that selection by winnowing is gone out and wet concentration produce adds catalyst (sulfuric acid), feeds steam, make pressure in 0.6MPa, temperature at 160 ℃, carry out the reaction of 1h.
(5) Separation of Solid and Liquid
After degradative reduction finishes, discharge excess liquid in the degraded equipment, handle through multiple-effect evaporation.
(6) spray quick-fried discharge
Solid material sprays quick-fried discharge in the presence of certain pressure, part moisture vapors away with steam, and the material water ratio of this moment is about 40%.Through extrusion dehydration, material water ratio can be reduced to below 30% again.Through the rubbish that degradative reduction is handled, process RDF.
Utilize this method disposal of refuse, processing speed is fast, and the processing cycle is short, thoroughly reaches the purpose of innoxious, minimizing, resource.
