The hot water supply apparatus using the perfect combustion of the waste and the method

The present invention relates to a hot water supply device and method by the complete combustion of waste for incineration of various combustible wastes such as waste tires, waste plastics and hot water, more specifically, the outer wall of the outer case surrounding the outer peripheral surface of the incinerator The water is supplied between the inner wall and the inside of the incinerator transfer screw located in the center of the incinerator, so that the water is heated using the heat generated during the combustion of the waste to supply hot water for heating and at the same time, the incinerator transfer screw It does not overheat and deforms, and in order to completely burn waste and waste tires, the oxygen supply required for incineration is smoothed by the discharge of air through the air supply pipe on the inner circumferential surface of the incinerator, and waste is discharged through the first incinerator ash outlet and the second incinerator ash outlet. It is easy to remove dust and incineration after incineration. , It will through the noxious gas emissions of the hot water supply apparatus and method according to the complete combustion of waste is the complete removal of toxic gases formed.

Conventional hot water supply apparatus by burning wastes does not use the heat generated during combustion efficiently and discharges it to the outside or installs a small tank additionally to reheat the water through secondary combustion. Waste heat was recycled. In addition, the waste fuel was burned while being transported from the incinerator using a screw to supply waste fuel, but at this time, there was a problem in that the screw was deformed due to the high temperature inside the incinerator, and the incinerator or dust was properly collected after incineration. Workers must collect and remove dust or incineration by hand, and when incineration incineration is not smooth, the combustion of incinerator is not complete combustion, and incomplete combustion causes serious gas and air pollution. It was serious.

The present invention is to solve this problem is to efficiently use the heat generated during the combustion of waste to supply hot water for heating, and to prevent the incinerator transfer screw inside the incinerator deformed due to overheating, the first incinerator ash outlet after incineration And 2nd incineration ash outlet to simply remove dust and incineration without any inconvenience to the operator, and fully burn the waste through supply of sufficient air to suppress the generation of harmful gases harmful to the human body, The aim is to minimize air pollution.

In order to achieve this purpose, water is supplied by forming an empty space between the inner wall and the outer wall of the incinerator outer case, and the incinerator transfer screw in the center of the incinerator forms an empty space inside the screw blade and the screw shaft to supply water. The first incineration ash outlet and the incineration ash conveying part are formed, and the second incineration ash outlet is formed at the outlet of the incinerator to easily remove dust and incineration, and the air discharge pipe having a plurality of air discharge holes perforated on the outer circumferential surface of the outer case. The present invention is characterized in that the supply of air is smooth and the complete combustion iron wire is formed in the noxious gas removal unit to completely burn the partially incompletely burned combustion gas to completely remove the noxious gas.
