Description

Solid Apparatus for Forming Refuse Fuel {The Apparatus for Forming Refuse Fuel}

The present invention is a solid fuel alternative fuel forming apparatus. In detail, wastes of high heat value (more than 4000Kcal / Kg) are collected from the wastes, and the metals and other non-combustibles are sorted and removed, and shredded and dried to a certain size to average calories (7000Kcal / Kg) is a waste recycling solidification device for molding the mixed waste to be.

Conventional industrial wastes and municipal wastes have been generally incinerated and landfilled, but this method has many problems such as NIMBY phenomenon and landfill shortage due to incineration not only in environmental protection but also economic and social aspects. Proper and effective alternatives are urgently needed.

When waste treatment is required to solve the above problems, eco-friendly treatment of waste and use of it as alternative energy leads to the accumulation of national economic resources and productivity improvement in the industrial society, thus creating economic and social added value. It is expected.

Conventional waste disposal methods cause problems such as air pollution due to incomplete combustion and lack of prevention facilities, and soil pollution due to landfill. The same waste treatment system will have to be completely reconfigured.

In order to solve the above problems, the present invention solidifies the high-calorie polymer compound (synthetic resin, synthetic rubber, synthetic fiber, PP, PE, etc.) that increases the air pollution during incineration, especially among industrial wastes and household wastes. The purpose is to recycle waste.

To achieve this goal, waste is recycled through systems such as sorting, crushing, drying and molding.

This system collects and sorts the raw materials from industrial wastes and household wastes from the home, which can be fueled, and accumulates them (high calorie value, heavy calorie value, calorific value, etc.) and mixes these wastes together. Mixing control unit, the sorting device unit for transporting them and sorting the non-combustibles, the crushing device unit for cutting and crushing the selected waste uniformly, the rotary drying unit for mixing and drying the crushed waste (15% moisture content) It is composed of a solidification molding unit and the like that is molded uniformly.

Hereinafter, detailed embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a process chart for recycling waste fuel by using the present invention, and FIG. 2 is a detailed view of a characteristic molding apparatus of the present invention, and a high-molecular value polymer compound (synthetic resin, synthetic rubber, synthetic fiber) of industrial waste. Etc.) and stockpiles (8) for collecting and storing wastes such as waste furniture, waste wood, and waste paper at high heat, medium heat, and low heat, etc., and mixing and inputting them so that appropriate calorific value (6500 Kcal to 7000 Kcal / Kg) is formed. Adjust the size and condition of the raw material approximately in the raw material supply tank (9) to supply, belt conveyor sorting device (1) to remove metals and other non-combustibles among them, and shredding device (2) to cut and shred it to a certain size. do.

Since the crushed waste has an average moisture content of about 35% to 40%, it is dried by about 15% using a rotary kiln device (3) as well as adjusted to sufficiently mix the crushed raw materials and to supply a fixed amount. Consists of a supply device 4 and a molding device 5 for solidifying the same, and the molded solid fuel is sized and packaged through a grinding device 6 according to a use.

In the raw material input device (9), a certain ratio (high heat is 25%, medium heat is 50%, low heat is 25%) is added according to the type of waste, and raw materials are introduced. In the sorting device (1), metals and glass bottles contained in the waste are input. The purpose is to remove the non-combustibles such as, stones, etc. to prevent wear of the crusher and to improve the efficiency of the molding machine during molding.

In the sorting method, it is possible to remove impurities such as soil by firstly sorting by hand using manpower, secondly by sorting metals by using magnet magnet, and thirdly by vibrating screen conveyor.

In the shredding device 2 for shredding waste, the sorted waste is cut or shredded into 5 cm to 10 cm in size to mix or homogenize raw materials for each component.

The device for drying the crushed and crushed wastes (3) is a rotary kiln device that has a function of drying raw materials having an average water content of 40-50% to 15% or less of moisture and a sufficient mixing of various wastes. Kiln) and the heat input to the kiln is dried by hot air by the hot wind generator 7 to burn waste material as a direct heat to prevent generation of gas. In addition, the drying device is equipped with a control device such as drying speed control is a special kiln device for waste drying that can obtain a predetermined drying effect uniformly.

The waste raw material dried and mixed in the kiln device 3 is input and supplied to a molding machine through a fixed amount supply device 4 to balance the quality of the product as well as to enable automation in the molding part. Device.

Molding apparatus 5 for solidifying the waste is the heat transfer coil plate 21, the twin screw 20, the extrusion die 22, the gas discharge doctor device generated during molding as shown in the detail (Fig. 2) When the mixed waste raw material dried in the fixed-quantity supply device (4) is constantly put into the molding machine, the mixed waste material is transported by the twin screw (20) and molded and extruded through the extrusion mold (22). The average temperature is fixed at 450 ° C. by the heat transfer coil plate 21 attached to the outside of the elliptical mold supporting the screw, so that the molding state of the product is always homogeneous.

The mechanical operation of the most important parts of the molding process is homogeneous by uniform operation of the raw material in the metering supply device 4, the constant internal temperature by the heat transfer plate, and the operation of standardizing the molding movement speed of the twin screw 20. It is possible to produce a product of the product, and the pyrolysis gas discharged at the extrusion port is introduced into the hot air generator 7 used in the drying device 3 through the discharge doctor 23 has the effect of the interconnection device that can burn the exhaust gas. .

Since the molded article extruded from the molding apparatus 5 has a variety of sizes and shapes, it is very inconvenient to use it as a fuel, so it is ground to a diameter of about 3 Cm in the grinding and crushing apparatus 6 and fuelized as an alternative energy using a separate combustion apparatus. Is possible. At the time of fuelization, the heat of fuel is about 6500Kcal / Kg ~ 7000Kcal / Kg, so it is possible to automate or continuously supply as needed, so that the combustion apparatus is diversified to achieve the desired purpose. Can be obtained.

As described above, the solid fuel molded by the solidification molding apparatus of waste is not only recycled waste and recycled as alternative energy, but also all the processes and individual devices in the treatment process are composed of eco-friendly systems. Is large.
