Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention can be used as a fuel for heating and combustion and as a fuel for an internal combustion engine by converting a liquid which is difficult to treat industrial wastewater or a highly water-containing waste oil into an emulsion fuel. Replenishment of necessary oxygen enables uniform and complete combustion at a theoretical air volume or less, so that harmful exhaust gases such as nitrogen oxides and carbon monoxide and CO ₂ can be reduced. Furthermore, since excess air is unnecessary, it is possible to prevent a decrease in flame temperature and reduce fuel consumption.

[0002]

2. Description of the Related Art Conventionally, in-furnace spray evaporation and indirect heating vapor methods have been used as treatment methods for waste liquid water. The conventional method has a problem that it is difficult to evaporate at a uniform and stable temperature, and the processing cost is increased due to the consumption of fuel and an increase in exhaust gas. Further, the combustion structure of the burner is composed of a fuel spray device, a combustion air blower and an ignition device, and cannot be uniformly super-finely atomized. Therefore, excess air is required for complete combustion, so that the combustion flame temperature and the calorific value decrease. Further, there is a problem that harmful exhaust gases such as nitrogen oxides are generated due to extremely high temperature combustion.

In order to achieve the above-mentioned object, the present invention comprises a tank for mixing and circulating oil and wastewater, a vortex emulsifying device connected to a pump and piping by quartz and a magnetic force, and a pump control device. Emulsion fuel production and supply equipment. In addition, an oil feed pipe that supplies fuel with a vortex spray nozzle, an air compressor that sends combustion air, and an ignition control device, an ultra-micronizing device that disperses oil and wastewater particle diameters ultra-micron to increase the surface area and increase the combustion speed. It is characterized by being constituted by a complete combustion device using a two-fluid gaseous spray with a reburn cylinder.

[0005]

The temperature and calorific value of the apparatus according to the present invention are almost the same as those of the fuel usually used in a boiler, a heating furnace and an incinerator using waste liquid emulsion fuel. Furthermore, as a result of analyzing the amount, composition, and water content of exhaust gas, C
The generation amount of harmful gases such as O, NO _x , HCLSO _x , etc. is several p
pm or less.
