3D Printing Multi-Channel Large Volume Microchannel Reactor for Enhanced Removal of Low-Concentration NOx Flue Gas

Compared with conventional reactors that are designed by traditional micromachining technology, the use of 3D-printing technology to manufacture multichannel large-volume microchannel as reaction equipment remove low-concentration NOX wet method is simple and convenient, processing cost low. The results showed when concentration NO was 400 ppm, mixed solution (NH2)2CO mass fraction 3% H2O2 0.5 mol/L used, flow rates gas liquid were 100 mL/min, respectively, under experimental conditions pH = 11, temperature 20 °C 500 mL recycling for min, best removal effect achieved, efficiency 100%. When O2 content in flue increased number length microchannels increased, accordingly, which conducive rapid efficient reaction. application reactor presents a new improving air quality reducing environmental pollution future.
