Abstract
The invention discloses a mixing grid and an oxidation-reduction reaction device, and belongs to the technical field of oxidation-reduction reaction. The mixing grid comprises at least one group of annular grids and at least one group of V-shaped grids. Each group of annular grids and each group of V-shaped grids are arranged between a first cylinder body and a second cylinder body. Each group ofannular grids comprises a plurality of annular grid strips which are arranged at intervals, and the plurality of annular grid strips are arranged on the same plane; each group of V-shaped grids comprises a plurality of V-shaped grid strips which are arranged at intervals, and the opening direction of each V-shaped grid strip faces the inlet of a reactor. When the oxidation-reduction reaction is carried out through the mixing grid, gas to be reacted can flow along the side faces of the V-shaped grid strips to be diffused in a sector shape, and the turbulence intensity of the gas to be reacted in the mixing grid is increased, so the concentration of the gas to be reacted entering the reactor can be balanced, and the problems that the reaction rates of all positions in the reactor are inconsistent and the reaction uniformity is poor are solved.
Description
technical field [0001] The invention belongs to the technical field of oxidation-reduction reaction, and in particular relates to a mixed grid and an oxidation-reduction reaction device. Background technique [0002] The mixing grid is a device arranged near the inlet of the reactor to improve the uniformity of the gas to be reacted inside the reactor. [0003] In the related art, the grid bars in the hybrid grid are generally cylindrical steel bars arranged in an array. The gas to be reacted can pass into the mixing grid from the gas delivery port, and under the action of the grid bars arranged in an array, the gas to be reacted can be uniformly mixed with the air. The uniformly mixed gas to be reacted can be passed into the reactor. [0004] However, the mixing effect of the mixing grid is poor, so that the concentration of the gas to be reacted in various places inside the reactor is inconsistent, resulting in inconsistent reaction rates and poor reaction uniformity in ...
