Field of the Invention
The present invention relates to a drain water reformer for reforming drain water generated in the exhaust system for exhausting the exhaust gas.

According to the fifth aspect of the present invention, the engine (20) is provided with the opening / closing means (46) for opening / closing the electrical connection between the metal member (42, 43, 44) and the exhaust member (32, 33). By connecting the opening / closing means (46) when the engine is operating, reforming of drain water generated from the operating engine (20) can be facilitated, and it is simpler than the system of electrolysis Drain water reformer with the following structure.
According to the sixth aspect of the present invention, when the exhaust gas containing the acidic component is cooled by the exhaust system (30), the vapor of the acidic component in the exhaust gas is condensed to become acidic drain water. When metal members (42, 43, 44) made of magnesium material are immersed in the drain water, Mg ²⁺ ions are dissolved in the drain water from the metal members (42, 43, 44) . When Mg ²⁺ ion dissolves in drain water , this Mg ²⁺ ion reacts with OH ⁻ to react with Mg (OH) ₂ and HNO ₃ and H ₂ SO ₄ contained in drain water, and ₃ Mg (NO ₃ ) _{Since 2} and MgSO ₄ are generated and mixed with the drain water, the acidic drain water is reformed to be neutral or alkaline. In addition, since the metal members (42, 43, 44) are consumed by dissolving Mg ²⁺ ions, maintenance for periodically replacing the metal members (42, 43, 44) is required, The frequency of maintenance can be less than that of the conventional method in which the neutralizing agent (calcium carbonate) is charged and dissolved. Further, this magnesium material has active dissolution characteristics in the acidic to neutral region, but in the alkaline region, it becomes stable because it generates an immobile body, so dissolution does not proceed in this region. Therefore, the metal members (42, 43, 44) are not consumed when immersed in the alkaline modified drain water. In addition, as Mg ²⁺ ions are dissolved, magnesium, which is one of the minerals contained in the water supply, is dissolved, so that it can be discharged directly to the sewer and there is no concern about environmental pollution.
