Plate Design for Mixer Sparger

Abstract

An apparatus is disclosed for the generation of hydrogen peroxide. The apparatus is designed to allow for a greater range of tolerances in its manufacture. The apparatus provides for the production of a large scale volume of hydrogen peroxide by the generation of a liquid bearing bubble cloud. The bubbles are generated with a tiny volume before flowing over the reactor bed to generate the hydrogen peroxide.

1 . An apparatus for mixing at least two gases comprising:
 at least one first plate having a first side and a second side, wherein the first plate has a first plate main channel defined in the first side and the first plate main channel has an inlet and a plurality of outlets, and a plurality of first plate secondary channels defined in the first side wherein each first plate secondary channel has an inlet in fluid communication with a corresponding first plate main channel outlet and a first plate secondary channel outlet, and at least one tertiary channel defined in the plate and extending through the plate with inlets in fluid communication with the secondary channel outlets and an outlet in fluid communication with the second side of the first plate; and   at least one second plate having a first side and a second side, wherein the second plate has a second plate main channel defined in the first side and the second plate main channel has an inlet and a plurality of outlets, and a plurality of second plate secondary channels defined in the first side wherein each second plate secondary channel has an inlet in fluid communication with a corresponding second plate main channel outlet, and a second plate secondary channel outlet;   wherein at least a portion of each first plate tertiary channel outlet is in fluid communication with a second plate secondary channel, and where the first and second plates are stacked in an alternating sequence with the first plate second side in contact with the second plate first side, and held together to form a gas sparger having a first gas inlet, a second gas inlet, and a plurality of mixed gas outlets.   
     
     
         2 . The apparatus of  claim 1  wherein the first plate tertiary channels are substantially perpendicular to the secondary channels. 
     
     
         3 . The apparatus of  claim 1  wherein the main channels are substantially perpendicular to the secondary channels. 
     
     
         4 . The apparatus of  claim 1  wherein the tertiary channels have an effective diameter of less than 300 micrometers. 
     
     
         5 . The apparatus of  claim 1  wherein the mixing section of the second plate secondary channels have an effective diameter of less than 300 micrometers. 
     
     
         6 . The apparatus of  claim 5  wherein the mixing section of the second plate secondary channels have an effective diameter of less than 200 micrometers.
