Air medium velocity uniformity directly affects the drying effect when large Vertical Cuttings Dryer is functioned indoor.
Based on the research of the wind speed field uniformity in drying chamber, as to provide theoretical basis for research and development of large vertical cuttings dryer. Mainly through uniform wind board are installed in intakes and change material surface roughness measuring wind speed value in drying chamber, analysis and wind plate and the material surface effects on medium speed uniformity.Results show that the vertical dryer into the wind and the wind plate is installed inside,
on both sides can obviously improve the medium into the drying chamber and through the dry material of medium air velocity uniformity, compared with without uniform wind board, set the short well after the wind plate of 360 mm, medium into the drying chamber a and b duct inlet velocity uniformity of reduced by 73.67% and variation coefficient of 73.67% to 22.27% and 29.36%, medium speed within the scope of the drying chamber plane through the material uniformity coefficient of variation of the reduced from 40.3% to 40.3%.
Material surface roughness affect dry indoor wind field. Drying room area is Large vertical dryer large, and adopts the profile into the wind, the uniformity of dry indoor air velocity field of medium is one of the important factors that affect the drying effect.
Multilayer belt drier, the spray chamber through dryer of the dryer dry indoor the uniformity of temperature field and velocity field and its influence on the effect of drying on the material for a number of research, found the dryer drying chamber is uneven distribution of wind speed and lead to low efficiency of drying, drying of the main causes of uneven.
Therefore, the study on the large vertical dryer dry indoor velocity field, especially the uniformity of wind field seems important.
