NOVELTY - Industrial exhaust energization system comprises a carbon dioxide absorbing device (1) connected with a nitrogen separating device (13), a first deoxidization column (7) connected with the carbon dioxide separating device. The first deoxidization column is connected with a synthetic gas fermentation strain growth tank (8) and a synthetic gas fermentation strain fermentation tank (10). The carbon dioxide separating device is connected with e.g. a micro algae culturing device, a micro algae and micro algae culturing liquid separating device and a micro algae separating device.    USE - Used as an industrial exhaust energization system.    ADVANTAGE - The device: organically couples micro algae oil production with synthetic gas fermentation strain fermentation, as it efficiently energizes carbon dioxide and carbon monoxide in the energized exhaust and obtains ethanol and diesel and a small amount of acetic acid by product; achieves energization by processing all components of industrial exhaust by biological methods, thus relieving environmental pollution caused by industrial exhaust.    DETAILED DESCRIPTION - Industrial exhaust energization system comprises a carbon dioxide absorbing device (1) connected with a nitrogen separating device (13), a first deoxidization column (7) connected with the carbon dioxide separating device. The first deoxidization column is connected with a synthetic gas fermentation strain growth tank (8) and a synthetic gas fermentation strain fermentation tank (10). The carbon dioxide separating device is connected with a micro algae culturing device, a micro algae and micro algae culturing liquid separating device, a micro algae separating device, a micro algae extract diesel reactor and a diesel output pipe. The micro algae culturing liquid return pipe is connected between the micro algae culturing device and the micro algae and micro algae culturing liquid separating device. The micro algae separating device is connected with a second deoxidization column, the synthetic gas fermentation strain growth tank, an acetic acid separating device, the synthetic gas fermentation strain fermentation tank, an ethanol separating device and an ethanol output pipe. A synthetic gas fermentation strain culturing liquid return pipe is connected between the acetic separating device and the synthetic gas fermentation strain growth tank. A bacterium culturing liquid return pipe is arranged between the synthetic gas fermentation strain fermentation tank and the ethanol separating device. An acetic output port of the acetic acid separating device is connected with the acetic acid output pipe which is connected with the micro algae culturing device by the acetic acid return pipe. The synthetic gas fermentation strain fermentation tank is connected with the carbon dioxide absorbing device by a carbon monoxide and carbon dioxide return pipe.
