Abstract
The present invention relates to treatment method for urban domestic garbage. The present invention comprises the following steps: taking and heating films, bags and flaky waste plastics in garbage which are contracted into irregular shapes of strips and blocks; pulverizing the films, bags and flaky waste plastics into particles with the maximum diameters of 3 to 5mm; taking and pulverizing combustible substances with high heat values in garbage into particles with the maximum diameters of 3 to 5mm; mixing the two kinds of particles according to a weight ratio and adding adhesive agents and calcium oxides and then rolling and molding the particles. The method effectively solves the basic problem that low heat values of the components of organic refuse prevent from improving the heat values of fuel-blocks of finished products by centralizing and treating the waste plastics in garbage and the combustible substances with high heat values which are difficult to treat with other garbage treating methods by artificial and mechanical sorting. The two kinds of particles of the present invention can be reliably contained by the calcium oxides to mutually isolate the particles of the waste plastics, which is favorable for sufficient combustion to reduce the occurrence amount of harmful gas, and the calcium oxides can maximumly adsorb the harmful gas, so the present invention has the advantage of obvious effect of restraining the generation of dioxins.
Description
Technical field
The present invention relates to a kind of treatment process of domestic waste.
Background technology
In the known technology of refuse treatment, directly burning and utilizing burning gained heat to generate electricity is more common method.But the waste plastic in the rubbish directly burns, and consequently certainly leads to two a large amount of evils because of waiting obnoxious flavour (Hce, Sox), causes atmospheric severe contamination.Dislike because of waiting obnoxious flavour even take technological measure such as secondary combustion can not thoroughly eliminate two, and its processing costs is quite expensive.Therefore it is the great technical barrier that is difficult to administer because of waiting obnoxious flavour that the direct waste disposal method that burns produces a large amount of two evils.
External " RDF " (Resuse Derived Fuel) technology at the early-stage, be that refuse reclamation is made solid-fuelled technology, be the waste plastic in the rubbish and other low heat value organic waste composition such as leaf of vegetable in its technological process, rhizome, pericarp and other food wastes etc. make it to become chip shape as pulverization process together, because the waste plastic of chip shape is overlapped with the fragment of Other Waste composition in treating processes, calcium oxide can not fully contain flaky waste plastic in the solid fuel to making, and calcium oxide inhibition two evils are relatively poor because of the effect that waits obnoxious flavour to produce when causing solid fuel ignition.Moreover, the solid fuel calorific value that waste plastic and Other Waste composition are handled institute's output together is also lower, only is (FDAC shipbuilding Co., Ltd. statistical information, Japanese worker seeks Co., Ltd. and provides) about 4000kcal/kg.
Summary of the invention
The present invention produces the inhibition that exists in the solid-fuelled known method two and dislikes the relatively poor and lower technical problem of solid fuel calorific value because of the effect that waits obnoxious flavour to produce in order to solve application " RDF " technology, produces the solid-fuelled method of high heat value and low pollution and propose a kind of domestic refuse of utilizing.
The present invention takes following processing method in order to solve the above-mentioned technical problem that exists in the known method:
1, take film, bag, sheet plastic waste in the rubbish through sorting, the heating bunching becomes irregular, block-shaped.
2, irregular behind the bunching, block-shaped plastic waste are ground into the particle that maximum diameter is 3-5mm.
3, taking the high heating value combustiblematerials that comprises bamboo and wood products, rigid plastics, chemical ﹠ blended fabric, rubber item and hard fruit shell in the rubbish through sorting, to be ground into maximum diameter be the 3-5mm particle.
4, with plastic waste particle and high heating value combustiblematerials particle with 25-40: 40-60 weight ratio thorough mixing is a base-material, adds caking agent and calcium oxide and thorough mixing in the base-material, is respectively 100 with the weight ratio of base-material: 5-8 and 100: 2-5.
5, roll forming.
The present invention can also take following method
The heating bunching of described film, bag, sheet plastic waste, its temperature are in 180-240 ℃ of scope.
Described caking agent is acetylene slag and/or flyash and/or clay.
Described calcium oxide is calcium oxide (CaO) and/or slaked lime.
The present invention has following beneficial effect and outstanding advantage: present method focuses on plastic waste in the rubbish and the reluctant high heating value combustiblematerials of Other Waste treatment process through artificial separation and mechanical sorting, solved effectively because of low heat value organic waste composition hinders the root problem that finished product fuel brick calorific value improves, the calorific value of solid fuel of the present invention can reach 5000-6000Kcal/kg.The more important thing is bunching of the present invention and pulverize after contain muriatic plastic waste particle and high heating value combustiblematerials particle can be contained by calcium oxide reliably, thereby blended high heating value combustiblematerials particle is isolated the plastic waste particle has mutually reduced the content of plastic waste particle in unit volume, consequently one side is impelled the plastic waste particle fully to burn and is reduced Hce, the generating capacity of Sox obnoxious flavour, the Hce that produces when plastic waste particle and high heating value combustiblematerials particle burning on the other hand, the calcium oxide that the Sox obnoxious flavour can reliably be contained absorption reaction to greatest extent becomes nontoxic gas and material, therefore solid fuel of the present invention has the very outstanding advantage of effect that can suppress the Dioxins generation, and the flue gas that burning produces is handled through routine and got final product qualified discharge.
Embodiment
Embodiment: with domestic waste through after mechanical grading removes large-scale special body size composition, again through gravity preparation, selection by winnowing, magnetic separation and cooperate artificial separation, remove brick and tile ash sandstone, glass-ceramic fragment, ferromagnetic material and other low heat value organic waste compositions such as leaf of vegetable, rhizome, pericarp and other food wastes, sort membrane, bag, sheet waste plastic and high heating value combustiblematerials such as bamboo and wood products, rigid plastics, chemical ﹠ blended fabric, rubber item and hard fruit shell etc. respectively.The hot flue gas that utilizes boiler in the refuse disposal system to discharge carries out the hot blast bunching to film, bag, sheet waste plastic becomes irregular, block-shaped.For the waste plastic that adapts to poly-second, poly-third, polychlorostyrene or the like different varieties is obtained satisfied pyrocondensation effect simultaneously, and the low melting point kind does not melt, and the temperature of hot flue gas is controlled in the 180-240 ℃ of scope to good with the method for regulating the cold wind ratio of mixture.
It is that diameter is stand-by at the particle of 3-5mm that waste plastic behind the hot blast bunching is pulverized by pulverizer.By pulverizer the various high heating value combustiblematerialss in the above-mentioned rubbish being pulverized equally is that diameter is stand-by at the particle of 3-5mm.
