Compared with the prior art, the application has the advantages that: according to the application, combustible garbage particles obtained by sorting and crushing decoration garbage are mixed with percolate, so that the mixing mode is improved, the heat value of garbage derived fuel is obviously improved, and the water content is reduced.
Firstly, in the application, the mode of directly mixing the percolate with garbage and then drying and crushing in the prior art is improved to attach the percolate before extrusion molding and discharging of combustible particles. In the prior art, the percolate and the garbage are directly mixed and then dried, the required drying cost is longer, the water removing effect is poor, because the percolate is directly sprayed on the surface of the garbage, water in the percolate can be absorbed by loose garbage, the water removing difficulty is increased, the percolate and the garbage are directly mixed, the percolate and the garbage are uniformly mixed, and after extrusion forming, the components of the mixture are uniform, namely, the inside of the garbage derived fuel also contains the components after the percolate is dehydrated, but in practice, in the combustion process of the garbage derived fuel, the combustion inside of the garbage derived fuel is insufficient, the combustible components in the percolate are difficult to fully utilize, the overall combustion time of the garbage derived fuel is longer, but the actually increased heat value is not increased in proportion, and the gain effect of the mixture of the percolate is further reduced.
Secondly, in the application, instead of simply adhering and mixing the landfill leachate with combustible materials in decoration garbage, the simple soaking mode is generally more suitable for substances with higher viscosity such as fuel oil or sludge in the prior art, the landfill leachate has higher water content and poor viscosity, and is difficult to be adhered to the surface for a long time, and the adhesive in-situ substitution mode is creatively adopted to adhere the leachate in the space occupied by the surface-layer adhesive in the refuse derived fuel (hereinafter, a fuel rod is taken as an example) during extrusion molding, namely, the adhesion stability of the combustible materials in the leachate can be obviously improved similar to adsorption and pinning on the surface layer of the fuel rod. Specifically, the adhesive is firstly mixed with combustible particles, centrifugal treatment is carried out before extrusion, the adhesive is distributed on the surface layer position of the fuel rod by virtue of centrifugal force, percolate is introduced during extrusion molding, the adhesive on the surface layer position occupies a certain space and is molded and solidified, the molded shape has gaps among particles and pits, grooves or holes, the percolate cannot be introduced into the fuel rod under the action of pressure, the adhesive is only adhered to the outer surface of the fuel rod, the adhesive is heated when approaching extrusion discharging, and is preferably heated in a gradient manner, the adhesive is enabled to recover fluidity in the heating process, and convection with a certain content is carried out after the adhesive contacts with the percolate, at the moment, the percolate is transferred to the space occupied by the adhesive, when the temperature is higher than the boiling point or the decomposition temperature of the adhesive, the original space can absorb the percolate under the action of negative pressure, thereby introducing the percolate into the space occupied by the adhesive, meanwhile, the moisture in the percolate under the high temperature is vaporized, the whole moisture content is reduced, the adhesiveness of the combustible in the percolate is improved, the combustible in the whole percolate is ensured to be fully adhered to the fuel in the whole, the heat value is also reduced, the whole heat value of the combustible in the percolate is also is improved, and the whole heat value is finished, and the garbage is fully mixed with the surface layer.
Finally, after the fuel rod is extruded and discharged, the volume of the fuel rod is expanded under the elastic recovery effect, but the compression degree of the outermost layer is maximum, the rebound degree is correspondingly larger, the space which is originally occupied by the binder is not influenced by the volume expansion, and even the openings of the spaces such as pits are reduced due to the volume expansion of the outer layer, so that the possibility of overflow of combustible substances in the percolate is reduced. On the basis, if the outer layer of the fuel rod is plugged by adopting the anhydrous combustible binder, the stability of combustible matters in the percolate can be further ensured, and the loss of the combustible matters in the transportation process is reduced.
