Description

Hot air generator using waste oil {HOT AIR GENERATING DEVICE BY USING WASTE OIL}

The present invention relates to a hot air generating device using waste oil, in particular, the outside air forcibly supplied into the combustion chamber by the blower is heated to a sufficiently high temperature by passing through the air supply pipe installed in a coil state inside the combustion chamber to completely burn fuel In addition, the exhaust gas and various pollutants in the exhaust gas is completely burned to maximize the thermal efficiency.

In the mechanized modern industrial society, various waste oils generated at numerous car repair shops and factories cause serious environmental pollution if they are not collected and disposed of properly. Such waste oils have high calories and can be recycled as energy. Although this is high, it is difficult to process and is incinerated.

Conventional techniques for incineration of waste oils mentioned above include Utility Model Registration Application Nos. 98-16058, Utility Model Registration Applications Nos. 99-15274 and 91-17544.

Utility Model Registration Application No. 98-16058 discloses a waste oil incineration boiler capable of functioning as a boiler with heat to incinerate waste oil by installing a heating chamber in which a central combustion chamber is provided and a tank surrounded by an upper portion thereof. This device was designed to have the function of a boiler that simply heats the water contained in the tank with the heat generated by burning the waste oil.Therefore, there was no system for incinerators to incinerate the waste oil completely. There was a problem that the environmentally harmful waste gas is ejected.

Utility Model Application No. 98-15274 has a long cylindrical combustion tube inserted into the lower part of the gas chamber, and a primary combustion part is installed at the lower part of the combustion tube, and a secondary combustion part is installed at the upper side of the gas chamber to install waste oil. A waste oil combustor for incineration is introduced, which is not a continuous incineration, but rather a process in which waste oil is first incinerated in a combustion tube located inside a gas chamber and unburned gas is moved for secondary combustion for second incineration. Because it must go through, there is still a problem to complete combustion in the secondary combustion unit.

In addition, Utility Model Registration No. 91-17544 is provided with a combustion chamber and a flow control tank, and is blown down the road under the upper upper and lower chambers of the combustion chamber for supplying air to the inner lower portion of the combustion chamber, and supplies air throughout the combustion chamber. Disclosed is a combustion apparatus for waste oil having a blower tube configured to supply the fuel so that the waste oil can be sufficiently combusted in the combustion chamber. The mixing ratio of air is very important for combustion, and it is a fact that it is the key to complete combustion. However, there is a problem that it is very difficult to achieve a sufficient complete combustion simply by supplying air as in the waste oil combustion device.

The present invention was devised to solve the above-mentioned conventional problems, and an object of the present invention is to solve the problems caused by the exhaust gas by completely burning the waste oil as a fuel, and at the same time, to heat the waste oil with high combustion heat. In addition, the present invention provides a hot air generating device using waste oil having a low operating cost to supply hot air to a greenhouse or a plastic house.

In order to achieve the above object, in the first embodiment of the present invention, an air supply unit forcibly supplying outside air by a blower into a combustion chamber made of a cylinder, a fuel supply unit for supplying waste oil into the combustion chamber, and an upper portion of the combustion chamber. In the air exhaust unit is provided, the air supply unit is installed to be wound in multiple stages while forming a coil form along the inner wall of the combustion chamber so that the air generated in the blower along the pipe to which the air is supplied is supplied to the inside of the combustion chamber and heated sufficiently. Is installed vertically in the center of the combustion chamber, and the air discharge hole is radially formed so that heated air is evenly distributed in the combustion chamber around the tube extending vertically in the center of the combustion chamber so that the waste oil supplied to the fuel supply unit burns. As the flames are generated from the lower part of the combustion chamber As the air inside the tube heats up, the temperature rises, and the air discharged to the combustion chamber from the vertical tube installed in the center of the combustion chamber becomes superheated and is discharged to help fuel combustion and to completely burn the pollutants in the fuel and discharge it to the exhaust section. The exhaust unit is provided with a hot air generating device using waste oil that can be installed to extend the heating duct to supply hot air to the greenhouse or vinyl house.

In the above embodiment, the waste oil is completely burned through the multi-stage combustion process by the superheated air that is combusted from the lower end of the combustion chamber and discharged to the multistage from the coiled tube, so that the contaminants in the exhaust gas can be completely removed.

In the second embodiment of the present invention, the outside air is first supplied to the vertical tube forming the air supply unit, and then passed through the coil-type tube, and an air discharge hole is formed inside the coil-type tube to heat the heated air in the center of the combustion chamber. Provided with a hot air generating device using the waste oil to be supplied to the combustion chamber through the outlet of the coil-type tube after the outside air introduced into the vertical tube is supplied in the superheated state by being concentrated to the vertical tube.

In the second embodiment of the present invention, as the fuel is burned in multiple stages from the lower part of the combustion chamber, hot air is discharged through the exhaust part after contaminants in the batch gas are completely removed without the release of unburned gas.

In a third embodiment of the present invention, the water is supplied to the air supply unit by a metering pump, and the supplied water is gasified into hydrogen and oxygen by air heated at a high temperature in the supply supply unit to form an emulsion, thereby completely burning fuel. Help.
