PURPOSE:To form an inexpensive highly reliable reaction tank by a method wherein a corrosion-resistance container taking charge of corrosion resistance and receiving no stress is provided in a pressure-resistant container and the outside pressure-resistance container takes charge of pressure resistance through the liquid having no corrosiveness received between two containers. CONSTITUTION:In a high pressure high temp. reaction tank handling a highly corrosive oxidizing process, pressure-resistant function and corrosion-resistant function are separated. A corrosion-resistant container 3 only taking charge of corrosion resistance and having no stress is provided in a pressure-resistant container 1 and the outside pressure-resistant container 1 takes charge of pressure resistance through the liquid having no corrosiveness (e.g., high b.p. oil) received between two containers 1, 3. As a result, the reliability of a reaction tank for cogeneration system also used in wet oxidizing system water treatment simultaneously realizing waste water treatment and the highly efficient generation of local energy can be enhanced and the cost reduction thereof can be achieved. |
