OXIDATION TOWER AND HYDROGEN PEROXIDE PRODUCTION APPARATUS COMPRISING OXIDATION TOWER

摘要

PROBLEM TO BE SOLVED: To provide an oxidation tower that can prevent at least a lower portion of a small oxidation tower positioned lowermost from having the accumulation of hydrogen peroxide, and provide a hydrogen peroxide production apparatus comprising the oxidation tower.SOLUTION: The present invention relates to an oxidation tower 10 that is for use in contacting an actuation solution with air at the time of producing hydrogen peroxide by anthraquinone method. The oxidation tower 10 comprises three small oxidation towers 12a to 12c that are vertically connected with one another. At least a small oxidation tower 12, positioned lowermost, is configured to allow an actuation solution to contact air in a counter current manner. The remaining towers, small oxidation towers 12a and 12b, are configured to allow the actuation solution to contact air in a parallel current manner.SELECTED DRAWING: Figure 1
