PROBLEM TO BE SOLVED: To provide an alkaline wastewater neutralization apparatus which can inhibit the adhesion of scales to a ventilation partition wall, and supply a combustion exhaust gas through ventilation slits over a long period of time. SOLUTION: The alkaline wastewater neutralization apparatus is equipped with a neutralization tank for neutralizing alkaline wastewater with the combustion exhaust gas. The neutralization tank includes an exhaust gas chamber into which the combustion exhaust gas flows, and a gas-liquid contact chamber into which the alkaline wastewater flows. The ventilation partition wall body 26 is installed between the exhaust gas chamber and the gas-liquid contact chamber. The ventilation partition wall body 26 is composed of a plurality of partition members 40 arranged at intervals in a predetermined direction. Each partition member 40 has a partition main body 42 whose both side surfaces form an inclined plane and a heat-resistant resin layer 44 covering the surface of the partition main body 42. The ventilation slit 36 is provided between the heat-resistant resin layers 44 of the adjacent partition members 40. COPYRIGHT: (C)2009,JPO&INPIT
