meanwhile, the organic waste gas discharging device starts to continuously supply organic waste gas into each organic waste gas injection pipe (11), the organic waste gas in the waste gas injection pipe (11) is transversely injected into the boiled liquid ethanol in the lower boiling gasification cavity (4) through a plurality of vent holes (20) in the form of bubble jet, the boiled liquid ethanol continuously generates gasified ethanol steam and continuously floats upwards, the transversely injected organic waste gas and the ethanol steam in a floating state generate continuous collision fusion below the liquid level (10) of the ethanol liquid, mixture bubbles of the ethanol steam and the organic waste gas are generated, the mixture bubbles of the ethanol steam and the organic waste gas finally float upwards and are broken at the liquid level (10) of the ethanol liquid and enter a bubble breaking and splashing cavity layer between the liquid level (10) of the ethanol liquid and the partition plate (2), the partition plate (2) also plays a role of preventing splashing liquid from entering the upper steam fusion cavity (9), then the mixed gas of the ethanol steam and the organic waste gas in the bubble breaking splashing cavity layer continuously overflows into the upper steam fusion cavity (9) through a plurality of steam overflow holes (18), the mixed gas of the ethanol steam and the organic waste gas in the steam fusion cavity (9) is further continuously fused, and then the pressurized mixed gas of the homogenized ethanol steam and the organic waste gas is generated in the upper steam fusion cavity (9), and further the mixed gas of the ethanol steam and the organic waste gas in the upper steam fusion cavity (9) is upwards sprayed out of a flame channel formed between the outer wall of the inner shell (5) and the combustion furnace body (7) through a gas spraying gap (19), and the mixed gas of the ethanol steam and the organic waste gas entering the flame channel is ignited by the combustion waste heat or an electronic ignition device, and at the moment, the mixed gas jet flow of the ethanol steam and the organic waste gas upwards sprayed out of each gas spraying gap (19) is sprayed to the top of the inner wall of the combustion furnace body (7), the mixed gas of the ethanol steam and the organic waste gas which is shot to the top of the inner wall of the combustion furnace body (7) is gradually and downwards diffused to the position of the bottom of the inner wall of the combustion furnace body (7) along the radian of the inner wall of the combustion furnace body (7), and the mixed gas of the ethanol steam and the organic waste gas is in a continuous combustion state in the process of gradually and downwards diffusing to the position of the bottom of the inner wall of the combustion furnace body (7) along the radian of the inner wall of the combustion furnace body (7), so that the organic waste gas is combusted and consumed in the combustion process, and combustion products which do not pollute the environment; and finally, the flue gas is discharged through a smoke discharge pipe (8), and the heat exchange water pipe (3) is coiled on the inner wall of the combustion furnace body (7), so that the heat exchange water pipe (3) is wrapped by mixed gas combustion flame of ethanol steam and organic waste gas, and is continuously heated, and the liquid flowing in the heat exchange water pipe (3) is continuously heated.
