| titleOfInvention | A performance optimization method for multiple working conditions of a mixer in a selective catalytic reduction denitrification device |
| abstract | The present invention relates to a multi-working-condition performance optimization method for a mixer of a selective catalytic reduction denitrification device, comprising: step 1, based on the size and structure of an actual SCR denitrification system, establishing a boiler economizer outlet and a denitrification device at a ratio of 1:1 The three-dimensional geometric model of the reactor, and discretize the three-dimensional geometric model, create a grid model, and build a numerical calculation platform; step 2, based on different types of mixers with the same windward area, numerically simulate the gas-solid two-phase in the SCR denitrification system The flow field and the mixing process of each component are analyzed, and the heterogeneity of the gas-solid two-phase flow and the ammonia-nitrogen ratio in the section above the catalyst is analyzed to determine the optimal mixer form. The invention can solve the problems of catalyst wear, high ammonia escape, excessive consumption of reducing agent, and blockage of air preheater caused by factors such as uneven gas-solid two-phase flow field, insufficient ammonia nitrogen mixing, and changes in the flow field at the denitrification inlet caused by deep peak regulation of the unit. . |
