Synergistic Effect Evaluation of Slot-Type Nozzle Area, Jet Pressure and Jet Distance on Improving Deashing Performance of Flat CARTRIDGE Filter

The difference of deashing performance between the areas positive-to-blowing holes and that non-positive-to-blowing is an important problem causes a non-uniform to flat box filter cartridge, which limits improvement raising ash cleaning efficiency this kind filter. In order solve above problems, influence blowing pressure, distance hole area on was studied. Industrial coating test also carried out investigate verify actual under optimal conditions obtained from investigations. Finally, design method size slotted optimized. results showed at 0.3 MPa pulse can meet requirements best uniformity be obtained. With increase in slot-type nozzle area, pressure facing non-positive nozzles increased significantly, thus overall increased. 273, 546 819 mm2 had effects jet distances 40, 20~40 20 mm, respectively. findings study are great significance provide theoretical experimental reference for parameters selection cartridges industrial application improve dust removal.
