| description | The utility model relates to a gas-solid catalytic reactor with an axial flow fixed bed, which mainly solves the problems in the prior art that reactant gas flow which crosses through a catalyst bed layer of the reactor is not distributed uniformly, catalyst can not be fully used uniformly, and the pressure drop of a preliminary distributor for gas is larger. The utility model has the technical proposal that reactor with an axial flow fixed bed, which is provided with the preliminary distributor with a conical single stage baffle plate for inlet gas, is adopted, and the height of the lateral annular space of the preliminary distributor for inlet gas is the height required for maintaining average flow speed of from 5 m/s to 12 m/s when the gas crosses through the annular space; the single stage baffle plate is a conical single stage baffle plate, and the conicl angle of the conical single stage baffle plate is from 90 DEG to 175 DEG. The problems are better solved, and the utility model can be used in gas-solid catalytic reaction. |
