PURPOSE:To enhance heat recovering rate by alternately superposing many flat and corrugated plates of a square including a rectangle so that the corrugated directions meet at right angles by turns; passing a gas to be treated through the resulting honeycomb-shaped catalyst bed from a side; and then passing the gas from other side intersecting perpendicularly to the first side. CONSTITUTION:Oxidation catalyst is attched to a honeycomb structure having passes intersecting perpendicularly by turns, and the resulting heat exchange type catalyst bed A is set in the center of shell 3. A gas to be oxidized is introduced from the A1 side of primary introduction chamber 4 through pipe 8 with blower 9 and taken out form the A2 side of primary taking-out chamber 5. The gas is then passed through the bed from the A3 side of secondary introduction chamber 6 to the A4 side of secondary taking-out chamber 7. Exothermic oxidation reaction takes place between the A1 and A2 sides, the residue is oxidized between the A3 and A4 sides, and exhaust gas is released from pipe 10. By this method a catalyst bed and a heat exchanger are unified to enhance heat recovering rate to 75-85%. |
