The invention develops an auxiliary design method for a catalyst based on a digital mirror image, and belongs to the technical field of fire coal denitration. The auxiliary design method comprises thefollowing steps of: establishing a catalyst single-duct model, and carrying out numerical value simulation and analysis on the single-duct model under multiple groups of different conditions; according to a great quantity of results obtained by the numerical value simulation, establishing a BP (Back Propagation) neural network model and a database; finally, utilizing the database to search an output parameter under a corresponding input condition to obtain a corresponding flow field situation; giving an inlet parameter condition of each single duct of a first layer of the catalyst, searchingaccording to the database to obtain an outlet parameter condition, and taking an upper layer outlet parameter as a lower layer inlet parameter. According to the auxiliary design method, the problems of long calculation time of
