Description

Thermal renewable energy generating device using mixed waste TECHNICAL FIELD

The present invention relates to an apparatus for generating heat renewable energy using mixed waste, and more particularly, a solid fuel is prepared by crushing mixed waste in a state in which various types of waste are mixed, drying, compressing, and molding at the same time with stirring. It relates to a heat renewable energy generating device configured to be manufactured and configured to generate heat renewable energy in a manner of recovering heat generated during combustion of the manufactured solid fuel.

In general, an incineration method or a landfill method is mainly used as a method of treating wastes such as household wastes generated during daily life, industrial wastes generated at industrial sites, and special wastes generated at medical facilities.

However, such incineration method requires enormous budget for installation and operation of incineration facilities, and air pollution caused by the discharge of hazardous substances generated when waste is incinerated is a problem, and the landfill method is an environmental pollutant contained in the waste. Land and water pollution due to the situation is a problem.

Therefore, as a means to solve these problems, a method of converting waste into fuel has been suggested and is being implemented in some countries, but there is still a lack of specialized technology for converting waste into fuel, and a method for removing harmful substances generated in the process of fueling is inadequate. Therefore, it has been reported that the operation of the facility is stopped due to an explosion or fire accident.

Conventional inventions for treating waste, such as converting waste into fuel, include “Organic Waste Solidification Treatment System” in Korean Utility Model Publication No. 20-0352790, and “Pellet Fuel Using Combustible Waste” in Korean Patent Publication No. 10-1460441. The molding device” has been proposed and disclosed.

In the “Organic Waste Solidification Treatment System” of the Korean Utility Model Publication No. 20-0352790, quicklime, briquettes, dolomite and slaked lime are added to the housing and then stirred for a certain period of time, and at the same time, recycled through a circulation pipe to solidify it. Invention for a device capable of rapidly manufacturing waste and compost and improving manufacturing efficiency at the same time has been proposed, and “Pellet fuel using combustible waste and its molding device” of Korean Patent Publication No. 10-1460441 has 40 to 80 A mixture of a plurality of combustible wastes such as waste urethane pulverized into mesh, waste stylofoam, sawdust, combustible sludge, petrochemical waste, etc. is used as a fuel material, and any one of paraffin, industrial binders, starchy vegetable binders or animal binders An invention has been proposed for an apparatus capable of producing and molding pellet fuel by mixing a fuel material and a binder at a predetermined mixing ratio using a binder as a binder.

However, the conventional inventions as described above are inventions related to a device for manufacturing fuel by processing the same kind of waste such as organic waste and combustible waste, and are regenerated by simultaneously treating mixed waste mixed with various wastes such as combustible waste and non-combustible waste. Since it has not been able to propose a way to manufacture raw materials, it is possible to treat such mixed wastes to produce solid fuel, which is a renewable raw material that can be used as an energy source. It is a situation in which an invention related to a device capable of processing a problem is required.
