The mode of classified recycling and utilization has been developed for a long time, but the mode still needs to be improved for the utilization condition of recycled materials, the simple recycling processing is delivered to other enterprises for further utilization, the material waste still can be caused, the garbage treatment degree is lower, the integration level is poorer, the gradual improvement of environmental protection requirements is urgent to further improve the in-situ centralized utilization of garbage treatment, the treatment efficiency of decoration garbage is improved, and more benefits are generated. In the prior art, there are schemes for improving the recycling efficiency of decoration garbage by utilizing recycled metal materials to treat and recycle the metal materials in the preparation of garbage derived fuels, but the disclosed schemes are generally aimed at iron-based materials, and further utilization schemes for aluminum-based materials are still lacking. The reason is that the content of aluminum alloy materials in the decoration garbage is higher (about 1-2%) than other garbage, but the conventional aluminum alloy recycling mode is that the aluminum alloy materials are recycled by melting after manual sorting or directly melting and recycling, and in most cases, the aluminum alloy materials are easily picked up and sold by a waster, finally the aluminum content in the decoration garbage entering a garbage treatment plant is greatly reduced, the aluminum alloy remained in the decoration garbage is often separated and difficult, the aluminum alloy is usually fixedly connected with the combustible material, and the aluminum alloy is combusted together with the combustible material with larger volume ratio if directly melting and recycling, so that the combustible material is wasted. The aluminum alloy is soft, and compared with the iron-based material, the aluminum alloy is difficult to granulate directly by crushing and other modes, and how to combine the recovered aluminum alloy into the utilization of other components of the decoration garbage is also a problem to be solved. In addition, a small amount of non-combustible matters such as lime, stone, gypsum, metal and the like are mixed after the combustible matters are primarily crushed, and if the combustible matters are directly used for extrusion molding, the heat value of the produced refuse derived fuel is affected and the refuse derived fuel is not easy to mold.

Specifically, firstly, in the application, the aluminum alloy obtained after the decoration garbage is separated and the aluminum alloy fragments recovered in the friction cleaning step are comprehensively utilized, so that the recycling rate of the aluminum alloy can be obviously improved. Moreover, through the friction cleaning step, on one hand, the purity of the combustible material is improved, the impurity content is reduced, the heat value of the fuel is improved, the generation of slag in the combustion process is reduced, on the other hand, the aluminum alloy block is crushed in two stages, the required size is obtained, the oxide film on the surface of the aluminum alloy is removed through the crushing process, the preparation is made for the subsequent hydrothermal reaction, meanwhile, the surface friction is carried out on the aluminum alloy fragments in the friction cleaning process, and part of the oxide film on the surface of the aluminum alloy fragments can be removed, so that the preparation steps before the hydrothermal reaction of the aluminum alloy are reduced.

In the obtained refuse derived fuel, the weight percentage of the aluminum alloy powder material in the fuel rod is about 5 percent, the quantity ratio is more than 85 percent, the calorific value of the fuel rod is increased from 3400 kilocalories/kg to 3800 kilocalories/kg in the traditional process, the Pb content in the product obtained by carrying out hydrothermal treatment on the fly ash after combustion is reduced from 2.6 mug/mL to 2.2 mug/mL when the powder material is not added, the Zn content is reduced from 0.43 mug/mL to 0.29 mug/mL when the powder material is not added, and the Cu content is reduced from 0.39 mug/mL to 0.31 mug/mL when the powder material is not added.
Example 2
On the basis of example 1, when the extrusion capability of the combustible is sufficiently high, the binder may be subjected to a degreasing operation, that is, in step S6, the temperature is raised to above the boiling point of the binder during the secondary extrusion, and the density and the heat value of the fuel rod may be further improved.
Comparative example 1
This comparative example differs from example 1 in that: in step S6, materials with the same proportion are directly mixed without secondary mixing and extrusion, the aluminum alloy powder material and the binder are uniformly mixed, and then the mixture is mixed with impurity-removed combustible particles, heating and ultrasonic treatment are carried out in the same way, and under the condition that the mixing time is the same as the sum of the two mixing times in the embodiment 1, the materials are extruded and molded through pressure of 8Mpa, and the diameter of the fuel rod is 5cm.

Therefore, the twice mixing process can improve the distribution uniformity of the aluminum alloy powder material in the fuel rod, thereby improving the heavy metal adsorption effect.
Comparative example 2
This comparative example differs from example 1 in that: the combustible materials are not cleaned by adopting the friction cleaning machine, sand, waste metals and the like mixed in the combustible materials can be separated only through crushing, manual selection and magnetic separation, the obtained non-combustible materials such as sand and the like in the combustible materials are difficult to remove, and the separated aluminum alloy is required to be subjected to manual removal of partial oxide films on the surface and then subjected to hydrothermal treatment, so that the labor cost is obviously increased. Further, in the case where the other steps were the same as in example 1, the heat value of the finally obtained fuel rod was 3650 kcal/kg. Therefore, the friction cleaning machine can obviously improve the purity of combustible materials, remove impurities and reduce labor cost.
Comparative example 3
This comparative example differs from example 1 in that: the processing sequence of the aluminum alloy is different, namely, the aluminum alloy fragments are pressed into a cylindrical shape or a strip shape, and then the aluminum alloy fragments are subjected to hydrothermal treatment and polished into powder. The area of the hydrothermal treatment of the aluminum alloy is obviously smaller than that of the embodiment 1 due to the first molding and the hydrothermal treatment, and the finally obtained fuel rod is tested, and the Pb content in the product obtained by the hydrothermal treatment of the fly ash after combustion is 2.5 mug/mL, the Zn content is 0.41 mug/mL and the Cu content is 0.37 mug/mL.
