ABSTRACT:
Chlorine dioxide is increasibly used to bleach pulp and the like. Chlorine dioxide is produced in a reactor, which contains a plurality of superimposed bubble cap trays, which are provided with passages for the gas and with duct, which is independent of the gas passages and serves as an overflow for the liquid. In order to maintain a maximum ClO.sub.3 /acid ratio for the longest time possible, the reaction chamber above each bubble cap tray is divided into a large number of reaction compartments by vertical partitions, which define openings for the passage of the reaction liquid. Acid can be supplied to each compartment. The partitions can be used to define in each reaction chamber any desired number of reaction compartments, which are connected in parallel for the flow of acid and are connected in series for the flow of the chlorate solution.
