HYDROTHERMAL REACTOR AND HYDROTHERMAL REACTION DEVICE

PROBLEM TO BE SOLVED: To provide a hydrothermal reactor in which there is a less fear of blockade when a liquid to be treated in which an inorganic salt is easily produced or a solid-like substance to be treated is treated and the concentration of the inorganic salt in the fluid to be treated can be made low. SOLUTION: The hydrothermal reactor 10 is a hydrothermal reactor in which the liquid to be treated is subjected to a hydrothermal reaction treatment and is provided with a closed type inner cylinder provided as a reaction cartridge; an upper part released reactor body 16 with a bottom accommodating the inner cylinder; and a reactor lid 18 for closing an upper opening of the reactor body. The hydrothermal reactor 10 is constituted as a double cylinder type pressure balance type reactor. In the hydrothermal reactor 10, the lower part of the inner cylinder mainly functions as a hydrothermal reaction area. A deposition mechanism 42 for depositing salts produced in the hydrothermal reaction area and a fine particle originally contained in the liquid to be treated is provided between a flow-in port 36a of a treating fluid leading out pipe 36 at the upper part of the inner cylinder and the hydrothermal reaction area. A plurality of stages of mesh plate (wire gauze) 44 crossing the inner cylinder and detachably provided is provided as the deposition mechanism 42. COPYRIGHT: (C)2004,JPO
