Description

FIELD OF THE INVENTION [0001] The present invention relates to a fueling apparatus and a fueling method for waste,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fueling apparatus and a fueling method for waste, and more particularly, to a fueling apparatus and a fueling method for waste that produce solid fuel by separately separating and separating combustibles from waste.

Recently, technologies and policies for securing energy using waste resources have been actively promoted to reduce GHGs due to resource depletion and climate change globally. In advanced countries such as Europe and Japan, Fuel (MT (Mechanical Biological Treatment) or MBT (Mechanical Biological Treatment) facility, which is the production technology of SRF (Solid Refuse Fuels), is increasing.

In Korea, the regulations on the quality standards of solid fuels, manufacturing facilities and storage facilities have been revised and enforced by the "Law Concerning the Promotion of Resource Conservation and Recycling", and nine fuel facilities are in operation as of 2013, Is under construction or planned.

Most of these refuse fueling facilities include a crusher 210 for crushing the waste, a screen separator 220 for screening the crushed waste, and an organic material A separator 230, a metal separator 240 for sorting the metals contained in the selected waste, a wind turbine 250 for sorting the waste selected from the metals by the specific gravity difference, An optical separator 260 for sorting by the light wavelength, a crusher 270 for crushing waste selected by the specific gravity and optically sorted waste, a drier 280 for drying the crushed waste, And is a molding SRF manufacturing facility in the form of a pellet having a molding machine 290 for molding.

In addition, some of the refuse fueling facilities include a crusher 110 for crushing the waste as shown in FIG. 1, a screen separator 120 for screening the crushed waste, and a screening device for screening the metal contained in the screened waste An optical sorting unit 150 for sorting the waste selected by the specific gravity by the optical wavelength, a sorting unit 150 for sorting the sorted waste by the specific wavelength, A non-shaped SRF production facility in the form of a fluff having a dryer 170 for drying the waste and a crusher 160 for crushing the waste sorted by the specific gravity difference.

The waste fuels project is being promoted in a positive manner, such as replacing fossil fuels, improving resource efficiency, and increasing the use period of waste landfills, beyond the conventional collective heat recovery method.

However, in most waste fuels, more than 30% of landfill residues are generated and recycled or incinerated, which is a contradiction in cost, environmental and energy recovery. Since these residues are buried or incinerated, additional operating costs are incurred, thereby deteriorating the overall economy of the fuel plant.

In the fueling process, the combustible component is recovered as SRF, which is a solid fuel, and the remnants remaining after the recovery are more than 30% of the input waste. The residues are mixed at a ratio of about 25% water, organic matter and inorganic matter in a ratio of about 50:50, and there is a slight difference depending on the fueling process, weather, and area. In addition, in order to recycle the generated residues and make them energy-efficient, the quality of waste fuel products should be met, such as water content of less than 25% and ash content of less than 20%.

In order to recover the combustible materials from the generated residues to improve the efficiency of the waste fueling facility, it is possible to improve the recovery rate of the whole combustible waste by improving the existing process and increasing the yield or installing a separate residue collecting facility.

However, the method of improving existing sciences is not good for the mass or operation of the existing process, but it can cause troubles of the existing process, and the method of recovering the residue by using the separate facility requires additional equipment installation cost, There is a problem in that the operating expenses required for the operation are increased.
