Description

The Apparatus of Recycling Wastes for a Substitute Energy

The present invention mixes and drys high-temperature waste (synthetic resin, synthetic rubber, PE, etc.) with waste wood chip (Chip) in a ratio of 2: 1 among industrial wastes. The present invention relates to an apparatus and a system for manufacturing a solid of a certain standard in a molding part so that it can be used as an alternative energy.

Conventional industrial wastes are partially selected and used as raw materials for recycled products. Poor conditions or large mixing of foreign substances are treated by incineration, landfilling, etc. In addition, it is difficult to build incinerators and landfills due to the proliferation of NIMBY phenomena among local residents, and as a countermeasure, the wastes will be used as solid energy for alternative energy.

In the meantime, some interested companies have tried to make alternative energy by shaping waste in various ways, but it is not only poor coarse molding due to lack of segregation collection, poor selection, raw material homogeneous and uniform mixing, but also combustion for alternative energy. When the contents melted or flowed down or became char, it was impossible to burn completely. This incomplete combustion caused dioxins, which had a negative effect on the social environment.

As a way to solve the above problems and put them into practical use, the present invention is designed to separate the wastes of each site and to mix them at a certain ratio according to the characteristics of the wastes and to quantify the waste wood chip mixing. It prevents spills and prevents the formation of char film coverings in the char state to completely burn out the solid fuel, thereby preventing the emission of harmful waste gases and also as a drying heat source of the wood chip drying apparatus 9. The purpose of the present invention is to use recycling heat generated by pyrolytic combustion of waste, and to recycle the waste heat discharged from the drying apparatus 9 to the mixed raw material drying apparatus 13.

In order to achieve the above object, through mixing and adjusting device 10 for mixing waste material and waste wood chips, which are high-molecular compounds, at a ratio of 2: 1 by weight, the mixture is mixed into a uniform raw material while the waste is pyrolyzed and burned. In order to suppress or prevent the generation of environmentally harmful substances such as NOx, SOx, and chlorine (Cl), an additive (lime as a neutralizer) is introduced into the mixed raw material by the injection dosing device 12a, and then the mixed raw material supply device 12 And a method of manufacturing a molded product having a size of Ø30m / m × L50m / m to be used as a recycled alternative fuel in the solidification molding apparatus 14 through a waste heat-drying apparatus 13.

In particular, in the drying apparatus 13, the waste heat generated from the wood chip drying apparatus 9 is used as a heat source to dry the water content to 15%. At this time, even if the burner is directly heated or indirectly heated, the temperature inside the kiln is maintained. When the temperature is above 150 ℃, the raw material, which is a synthetic polymer compound, may be plasticized and deposited on the wall. Therefore, the waste heat of the drying device 9 (220 ℃ ~ 250 ℃) can be prevented and the drying efficiency can be improved. It is a waste recycling plant that produces fuel savings by using a system.
