Abstract

<P>PROBLEM TO BE SOLVED: To provide a method for treating and effectively recycling a scrap vending machine without polluting the environment. <P>SOLUTION: After manually classifying and collecting fluorocarbon gas, battery, fluorescent tubes, and copper components of a cooling device in the waste vending machine, the remainders are charged in an electric furnace in an original shape, the flammables are burned as a combustion improving agent for melting, while non-flammables not melted in a molten steel are melted in a steel-making slag, and discharged in a pollution-free manner. When a plastic plate of a front panel is collected, the plastic plate is granulated, and used for a reduction-improving agent for cokes in collecting zinc in a steel- manufacturing dust. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing method for recovering the main body of a waste vending machine as iron scraps of a steelmaking raw material,
Further, the present invention relates to a method for reusing a plastic plate incorporated in the panel as a coke reduction aid.

[0002]

2. Description of the Related Art Conventionally, waste electric appliances and the like are generally crushed by a shredder and then iron is recovered by a magnetic separator, and nonferrous metal is recovered by a nonferrous metal separator or manually selected. It was being landfilled. on the other hand,
The amount of shredder dust generated has grown enormous with the demand for resource recycling, and there has been a shortage of landfill sites. For this reason, incineration is performed for the purpose of reducing the volume of shredder dust, and unburned material residue is landfilled as incinerated ash of shredder dust.

Further, a method of treating shredder dust is disclosed in Japanese Patent Laid-Open No. 11-1017, but it is considered that the utilization rate as a resource is low and recovery of treatment cost can hardly be expected. In addition, combustible materials such as plastics are incinerated during the treatment process and are not used effectively.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and solves an environmental problem that is inevitably generated during processing or increases the processing cost that is secondary. It is to solve the above problem and to provide an effective reuse processing method.

[0005]

According to the method of the present invention, in order to achieve pollution-free environmental problems, a fluorocarbon gas / battery / fluorescent tube and a copper structure of a cooling device are installed in a waste vending machine. Hand-select to prevent pollution from shredders. As a problem other than the above, by charging the main body after selection into the electric furnace as a steelmaking raw material in its original shape and melting it, the incombustibles in the residue generated by shredding are melted and solidified into steelmaking slag. Detoxify.

[0006] Japanese Unexamined Patent Publication No. 5-13272
From the technical knowledge obtained by the method of recovering zinc and lead from steelmaking dust in No. 1, plastics that incompletely burn in the rotary kiln are [Chemical formula 1] C + CO ₂ = 2CO, ΔG ° =
40800-41.7T (Boudouard real
It is presumed that it promotes the action. From this, the plastic plate incorporated in the front panel of the waste vending machine is pressed, crushed, and recovered, and is used as a coke reduction aid in the zinc-lead recovery system of electric furnace dust.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The main points of the implementation of the pollution-free processing method for a waste vending machine according to the present invention will be described below with reference to the drawings. Fig. 1 shows the case where CFCs, batteries, fluorescent tubes, and copper components of a cooling device of a waste vending machine are selectively collected and the remaining main body is inserted into the electric furnace in its original form, and only the front panel is pressed. This is an example in which a plastic plate is crushed and collected and charged into an electric furnace.

In FIG. 2, the crushed plastic is further pulverized by a crusher, and this is continuously charged into a rotary kiln as a reducing aid (equivalent to 2 to 5% of a predetermined amount of coke) and the steelmaking dust is reduced and roasted. In this example, zinc in the dust is recovered. FIG. 3 is an example of the result of improving the zinc recovery rate by the above implementation.

[0009]

The present invention has the following effects.

The amount of dust consisting of incombustibles and combustibles generated in the shredder process of the waste vending machine is about 200 kg per 100 standard vending machines, but the waste generated in the present invention is the dust collector of the electric furnace. There is only a small amount of dust that accompanies the original steelmaking dust captured in. Processing capacity is 70
Ton electric furnace 5 units per charge (Unit weight: 300k
It can be charged up to g) and can be processed appropriately.

If the plastic plate incorporated in the front panel of the waste vending machine is recovered, it can be used as a coke reduction aid in the recovery system of zinc and lead in steelmaking dust, and the recovery rate of zinc can be improved. You can
