Gas-liquid processing apparatus

摘要

The present invention is to provide a gas-liquid processing apparatus having a high contact efficiency of a gas and a liquid and a high reaction efficiency at a low production cost. A static type fluid mixer (30) comprises a passage pipe for the passage of a fluid and a spiral blade body arranged in the passage pipe with the longitudinal direction substantially perpendicularly but being absent in the center portion of the passage pipe. A liquid and a gas are supplied into the static type fluid mixer and a fluid is returned from the bottom portion of the static type fluid mixer to the upper portion via the pipe (36) for the fluid circulation. The fluid is maintained in the static type fluid mixer at a pressured state higher than the atmospheric pressure.
