description The difference of deashing performance between the areas of positive-to-blowing holes and that of non-positive-to-blowing holes is an important problem that causes a non-uniform deashing performance to a flat box filter cartridge, which limits the improvement of raising the ash cleaning efficiency to this kind of filter. In order to solve the above problems, the influence of blowing pressure, blowing distance and blowing hole area on cleaning performance was studied. Industrial coating test was also carried out to investigate and verify the actual ash cleaning performance under the optimal conditions obtained from the above investigations. Finally, the design method of the size of the slotted blowing hole was optimized. The results showed that at 0.3 MPa of the pulse pressure, the cleaning performance can meet the cleaning requirements and the best cleaning uniformity can be obtained. With the increase in slot-type nozzle area, the pressure at the areas facing the non-positive nozzles increased significantly, and thus the overall cleaning uniformity increased. The slot-type nozzle area of 273, 546 and 819 mm<sup>2</sup> had the best cleaning effects at the jet distances of 40, 20~40 and 20 mm, respectively. The findings of this study are of great significance and can provide theoretical and experimental reference for important parameters selection of the flat cartridges filter in industrial application to improve the efficiency of dust removal.
