Ozone water producing apparatus and gas-liquid mixture producing apparatus

摘要

Apparatus for producing ozone water (60) comprises: a gas-liquid mixing vessel (31) having a water-discharge port (38) near its bottom and a gas-discharge port (39) at an upper level; an inner vessel having an upper opening (40) below the level of the gas-discharge port; a main conduit (41) extending into the gas-liquid mixing vessel and opening at a lower level inside the inner vessel and having an upper end (35) connected to a source of water via a water-supply valve (42); a gas-induction conduit (36) having one end connecting to the main conduit and its other end connected to a gas-induction valve (43); a gas-discharge conduit (52) connected between the gas-discharge port and a gas-discharge valve; a communicating conduit (53) connecting the gas-induction valve and the gas-discharge valve; an ozone generator (20) connected to the communicating conduit; and an ozone-decomposing catalyst vessel (45) connected to the communicating conduit.
