Description

Melt incineration device using brown gas {ARTIFICIAL INTELLIGENCE SUPPLY BURNER DEVICE OF NANO-BUBBLED BROWN GAS}

The present invention relates to a brown gas system, and more specifically, to use the heat of the drying gas generated after pyrolyzing waste to melt char without wasting it. The char is converted into molten slag in the pyrolysis zone and then melted. The amount of brown gas used is minimized by using the enormous heat generated in the dry gas combustion area, and the installation area is minimized by installing a waste heat boiler on the top of the melting incinerator main body and installing a stack on the top of the waste heat boiler to form an integrated system. It is compact and does not emit pollutants, and maximizes the waste heat recovery rate by installing a thermal barrier between the plurality of water pipes formed vertically between the water chamber and the steam chamber of the waste heat boiler to prevent heated exhaust gas from escaping directly into the stack. This is about a melting incineration system using Brown gas that allows this.

In general, brown gas refers to a mixed gas in which hydrogen and oxygen produced by electrolysis of water are mixed at a mixing ratio of 2:1, and has four major characteristics unique to brown gas: completely pollution-free characteristics, complete combustion characteristics, and implosion. It is an ideal fuel with implosion characteristics and thermonuclear reaction characteristics, and is attracting attention as a clean fuel for the new era.

Such brown gas has the conditions for complete combustion of hydrogen and oxygen in a chemical equivalent ratio of 2:1, so there is no need for a separate air supply device and chimney to supply oxygen like in the conventional combustion method.

When brown gas is used for heating, there is a significant energy saving effect because there is no need for special ventilation, and since brown gas is reduced to water vapor after combustion, it also has a humidifying effect, allowing for comfortable heating.

Figure 1 shows a conventional brown gas pyrolysis melting furnace using brown gas as described above.

Referring to Figure 1, the conventional brown gas pyrolysis melting furnace has a vertical tunnel shape at the bottom, and is connected to a compression device 20 on one side, forming an incineration inlet 31 horizontally, forming a tunnel along the lower surface forming an inclined plane. It has a structure in which a tapping port 32 is formed at the end of the part that protrudes outward, and the tunnel-shaped space naturally forms a pyrolysis melting chamber (A).

The upper part of the main body 30 connected to the pyrolysis melting chamber (A) is greatly expanded to form a drying gas combustion chamber (B), and an exhaust port 33 is formed in the upper part of the drying gas combustion chamber (B), and the exhaust port 33 is connected to the rear end of the incinerator. The facility consists of a water-cooled cooling facility, an air-cooled cooling facility, a semi-dry reaction tower, a bag filter, an exhaust fan, and a stack.

In addition, the Brown gas burner 12 is mounted on a plurality of burner holes formed at certain positions on the furnace wall of the Brown gas pyrolysis melting chamber (A), and the first burner (12a) is located at the horizontal center line of the compressed incineration inlet (31). It is installed at a certain position on the furnace wall on the opposite side of the furnace, and the second burner (12b) is installed below the first burner (12a) to melt the char that falls after pyrolysis. In the same way, the third burner (12c) is installed on the inclined surface. It is installed horizontally so as to heat the top surface of the molten metal flowing along it, and a fourth burner (12d) is installed at the molten metal outlet (32) in the same manner.

In addition, the fifth burner (12e) is installed on the top of the first burner (12a) and the sixth burner (12f) is installed on the furnace wall opposite to it, so that the upper part of the pyrolysis melting chamber (A) is also maintained at a high temperature even if there is a scattering difference. It is configured to melt and fall.

However, in the conventional Brown gas melting furnace as shown in FIG. 1, the pyrolysis melt chamber (A) forms a vertically narrow turbine and has as many as six Brown gas burners from the first burner (12a) to the sixth burner (12f). The composition has been pointed out as a major problem. This is because the enormous combustion heat of the drying gas generated in the large space of the drying gas combustion chamber (B) constructed at the top only rises upward along with the brown gas combustion heat rising from the lower vertical tunnel, so the molten slag melting down from the melting chamber (A) is melted. This is because it does not provide any help and is wasted.

As shown in Figures 2 to 6, the melting and incineration system using brown gas according to an embodiment of the present invention includes a water energy plant 110 that turns tap water into fuel (brown gas) and supplies it stably 24 hours a day, 365 days a year. , a waste pyrolysis area (AA) in an internal space surrounded by No. 1 and No. 2 Brown gas burners (111, 112) that receive fuel from the water energy plant (110) and burn it, and the melting incineration chamber wall (121); A melting incineration chamber 120 that forms a dry gas combustion zone (BB) and a brown gas combustion zone (CC) and an exhaust port 123 at the top, and waste heat for recovering high heat rising from the melting incineration chamber 120. By installing the stack 136 on top of the boiler 130 and the waste heat boiler 130 and arranging it vertically, the exhaust gas generated in the melting and incineration chamber 120 naturally flows into the stack 136 by natural convection phenomenon and chimney effect. It is designed to be discharged through.

More specifically, the melting incineration chamber 120 forms a thermal decomposition area (AA) connected to the waste input device 140 on one side, and a ceramic material containing silicon carbide refractory (SiC) as a main component is installed in the burner hole on the opposite side. A Brown gas heating tube (113) made by compression molding is installed, and a No. 1 Brown gas burner (111) is installed on the Brown gas heating tube (113) to directly heat the waste. At the top of the melting incineration chamber (120) A dry gas combustion zone (BB) is formed with a plurality of external air inlet holes 122 on the four sides of the wall, so that the dry gas burns and generates enormous heat, and a brown gas combustion zone is formed at the bottom of the dry gas combustion zone (BB). It is configured to form (CC).

Therefore, the waste inputted into the pyrolysis area (AA) by the waste input device 140 is heated and pyrolyzed by the Brown gas fired by the No. 1 Brown gas burner 111 without blowing combustion air.

A 'U'-shaped pit 125 is formed along the slope at the bottom 124 of the melting chamber of the Brown gas combustion zone (CC) to allow molten metal to flow, and a No. 2 Brown gas burner 112 is installed at the outlet.
