A Study on the Filtration Characteristics of Baghouse with Tangential Inlet Depending on the Shape of Inner Tube

접선유입 방식 여과집진기의 내통형상 변화에 따른 집진특성 연구

A new type baghouse with tangential inlet and inner tube was developed and it's performances were evaluated. Experiments with variable shapes of inner tube were performed to suggest an optimum shape of inner tube which might decrease the dust loading onto bag filter surface and the amount of reentrained particles by internal gas flow. The dust loading was lower when inner tubes parallel to outer casing exist. When an inner tube covering around the lower portion of bag filters was used, the dust particles detached from the filter surface by cleaning process were reentraind by internal recirculating gas flow.
