Waste Treatment using Thermal Technology
An increase in the world’s population and an improvement in quality of human life have caused natural resource depletion as well as fossil fuel depletion. Fossil fuel depletion has been of particular interest, globally. However, material resource depletion has also become a serious issue. Recycled waste material has recently become of interest because of the massive amount of natural resource consumption worldwide. Therefore, the introduction of a material recycle system in municipal and industrial waste management is of vital importance. Even among them, quality improvement of recycled material is also one an issue. Quality of recycled material reduces the cost of new products which include recycled materials, as well.
Generally, metal waste collected by recycling business operators is melted directly by an electric steelmaking furnace or blast furnace without accurate sorting, and results in a low grade material which includes impurities. Various manual operations have been introduced as removable methods for impurities before the melting operation. In metalworking factories, numerous oily cutting waste chips are produced. The cutting oil which is included in the cutting chips acts as an impurity for the recycled metal. Some removal methods, such as compression, centrifugal separation or chemical dissolution, are introduced to remove oil from metal waste. The centrifugal separation method cannot remove oil well enough from metal due to the metal waste having a complex shape. The oil gathered in a recess remains on metal waste. On the other hand, if the oil is removed with chemicals, the oil dissolves into a chemical substance and becomes difficult to separate from the chemical agent. In addition, from an environmentally-conscious standpoint, it is difficult to dispose of liquid waste contained in the surroundings of the chemical substance.
Superheated steam has been a very popular heat source for industrial and municipal applications, such as air conditioning and boilers. In particular, most of the electric power supply is generated by using superheated steam turbine systems in a power plant. Superheated steam is a gas which is generated by heating saturated steam until it exceeds the boiling point. The steam can heat the materials by convection, radiation and condensation heat transfers. A drying system using superheated steam plays an important role in high-moisture material drying procedures due to the high thermal efficiency of the steam. For industrial application, the superheated steam is used to dry various materials, such as wood, coffee beans, vegetables, and raw garbage, based on special characteristics such as inert gas, high specific enthalpy and condensation heat transfer. When the processing chamber is filled with the superheated steam, a chemical reaction, such as ignition, can be prevented since the steam does not contain oxygen. Hence, fires or explosions cannot take place in the processing apparatus. It brings about safe operation, especially for waste processing. Similarly, this gas also presents useful features for waste disposal, including sterilization, degreasing and deodorization. Accordingly, the system using superheated steam has been very useful in waste processing. Nonetheless, in order to obtain superheated steam, a large amount of latent heat for water evaporation is required. Thus, it is important to cyclically use the steam without condensation. This results in high thermal efficiency.
Here, the superheated steam is introduced to improve the quality of metal waste disposed from metalworking factories as recycling materials. A practical steam circulation-type material recycle system is proposed. The waste material is heated by superheated steam under an inert gas atmosphere, and impurities are removed from the primary material.
