METHOD FOR MANUFACTURING SOLID BIO-CHARCOAL OF ENVIRONMENT-FRIENDLY LOW CARBON GREEN GROWTH BY UTILIZING INDUSTRIAL ORGANIC WASTES, AND THE SOLID BIO-CHARCOAL PRODUCED THEREOF}

The present invention relates to a method for producing a solid biotan and a solid biotan manufactured using the same, and specifically, selects only combustible materials excluding metallic materials from various industrial and organic organic wastes, and carbonizes them under anoxic conditions to produce carbides. And a method for producing environmentally friendly low carbon green growth solid biotan using industrial and domestic organic wastes that are mixed with emulsified oil produced when carbonizing the carbon and then producing biotan, and solid biotan manufactured using the same will be.

Combustion facilities such as thermal power plants, industrial boilers, and domestic boilers are widely used as energy generating facilities shared by most of them as basic production or heating facilities not only in homes but also in modern industries. This is reaching a considerable scale.

In addition, most of the fuel used for agricultural and agricultural crop cultivation is mainly briquettes and heavy oil (BC oil) due to the small size and lack of funds in rural areas. In addition, there are many problems such as adverse effects on crop growth and environmental pollution due to harmful substances such as carbon, dust, and carbon monoxide emitted from heating facilities due to deterioration of heating facilities, deterioration of thermal efficiency and use of fossil fuel. .

As a result of this situation, the international dependency on fossil energy such as coal or petroleum in Korea reached more than 97%, and domestic fossil energy consumption accounted for about 83% of total domestic energy consumption. It is equivalent to 10,000 tons / day, making it the world's second-largest importer of fuel coal, and generating about 590 million greenhouse gas emissions such as carbon dioxide (CO2), methane (CH4) and nitrogen dioxide (N2O), which are the main components of global warming and greenhouse gases. As it is one of the world's top 10 tons / year, it has been designated as a target of greenhouse gas reduction since 2013, so it is urgently needed to prepare for the low carbon green growth and green energy era.

As a problem of the existing fossil energy, significant carbon monoxide (CO) is generated during combustion, and ashes of coal or briquettes by incomplete combustion generate about 20 to 40% or more, and the weight is about 3.6kg per piece. As it is quite heavy, not only does it cause inconvenience in transportation or use, but also the calorific value is only about 3,000 kcal / kg to 6,000 kcal / kg depending on the type of fuel coal.

In addition, the disadvantages of coal or briquettes using conventional fossil energy are solid fuels and are difficult to catch fire, so they should be stored in a well-dried state. As described above, there is a disadvantage in that fatal toxic gas is generated.

In some cases, the technology for recycling the sewage sludge into fuel has been developed, but in this case, unlike most of the present invention, the existing coal fuel is mixed and used at a predetermined ratio, which may generate some expectation in terms of energy saving effect. However, the low carbon monoxide (CO) emission in terms of reducing the environmental pollution is not a big feature, and most of the existing technologies for fueling sewage sludge or producing only emulsified oils, such as coal, additives or waste plastics It is manufactured by mixing waste, and this technology is known to be very harmful to the human body by generating a carcinogen dioxin, etc. during combustion by additives contained in waste plastics while increasing the calorific value. Only increase the heating value of the fuel itself And pollution reduction side is substantially not considered described as that, is technically much difference in the present invention considering the case with both the amount of energy exploitation of resources and environmental pollution reduction.

In addition, some of the existing fuel pellets produced from agricultural or forest products such as straw bales, rice bran, corn stalks, soybeans, lumber, and waste wood are carcinogenic to heavy metals or harmful components such as benzene, formaldehyde, lead and cadmium. A large amount of substances, etc. may be generated, which may have a great effect on human injury.

On the other hand, industrial and organic organic wastes such as waste tires, waste plastics, and sewage sludge, which are rapidly increasing each year as a highly industrialized society is formed, are produced by industrial organic sludges from concentrated livestock and various industrial wastewater and sewage, sewage or wastewater treatment plants. Occurs over 4 million tons / year, and organic waste such as household waste occurs over 4.1 million tons / year, and various industrial wastes generate more than 3.5 million tons per day, as well as agricultural and forest products, including thin trees and waste wood. The annual output is about 3.5 million tons or more, and there are many problems in supply and demand for subsidies or economically and socially.

The present invention is to solve the above problems, by selecting only the combustibles from various industrial and living organic wastes and carbonizing them under anoxic conditions to produce a carbide and then mixed with the emulsified oil produced when the carbide is carbonized Method for manufacturing environmentally friendly low carbon green growth solid biotan using industrial and domestic organic waste that makes various industrial and domestic organic wastes into bioenergy by manufacturing new renewable energy biotan and solid biotan manufactured using the same The purpose is to provide.

In addition, unlike the conventional waste fueling technology, the present invention does not mix environmental pollutants, such as chemical additives or conventional coal, with carbides, thereby preventing industrial and municipal organic wastes from being released. Another object of the present invention is to provide a method for producing environmentally friendly low carbon green growth solid biotan and a solid biotan manufactured using the same.
