SUMMARY OF THE INVENTION The present invention provides an emulsion manufacturing apparatus having a simple mechanism for solving the above-mentioned problems, a burner capable of burning all fuels, and high-efficiency power generation using exhaust heat. Aim for a highly efficient cogeneration system.

[0004]

In order to solve the above-mentioned problems, the present invention connects a waste oil tank 1, a surfactant tank 2 and a water tank or tap water 3 to a pre-mixing tank by pipes, and determines each quantity. A long-term stable emulsified fuel can be produced by putting the mixture in a mixing tank, connecting it to the quartz-equipped swirl-impact mixer 6 by a pipe 5 with a circulation pump 4, and circulating it through an ionizer 7 by an alternating magnetic force a plurality of times.

As a means for cleanly burning the above-mentioned emulsified fuel, a high-pressure air compressor is used for fuel atomizing, and a swirling vortex flow external two-fluid atomizing nozzle 9 with a compressed air inclined slit is used to produce ultrafine atomization and swirl secondary air. It is possible to induce a water gasification reaction of water in the multi-stage combustion cone 11 and stably continue heat storage complete combustion. The ignition method is LPG
With gas ignition 12, turndown provides an emulsion burner 8 with stepless proportional control by adjusting the pressure of fuel supply valve 10.

As a method of using the above-mentioned emulsified fuel for industrial equipment, in order to convert exhaust heat loss into energy by using it as fuel for existing combustion furnace 13, boiler / gas turbine engine 14 and diesel engine 15. , Install Stirling engine generator 16 to supply power,
Furthermore, a hot water supply and absorption heat cooling / heating heat exchanger 18 is installed downstream thereof, and a plurality of Peltier elements 19 for power generation are arranged in place of heat insulating materials such as a combustion furnace or a boiler, an engine body and an exhaust stack to supply electric power. Enables a highly efficient cogeneration system.

[0007]

When water is added to waste oil and is circulated in the emulsifying apparatus of the present invention, a stable water emulsion fuel having ultrafine particles can be produced in a short time at low cost. This emulsified fuel is hard to vaporize at room temperature, and it is safe to move and store at a high flash point.

Further, the above-mentioned fuel is ignited at room temperature with a simple facility in a dedicated emulsion burner, and even if the water content is 50%, the flame temperature is 1200 ° C. or higher, CO-0%, NOx10.
Can clear ppm or less and O ₂ concentration of 4%. This phenomenon enables complete combustion by oxygen-hydrogen combustion in a water gasification reaction, and effectively acts as energy saving due to non-adhesion of carbon in a boiler or the like and prevention of global warming due to CO ₂ reduction.
