Abstract
A kind of novel fixed rotary valve trays was presented through several improvements of traditional fixed valve trays. The hydrodynamic performances of the fixed rotary valve trays were experimentally investigated with an air-water system in an organic glass column with an inner diameter of 600 mm. The pressure drop,weeping fraction and entrainment of the fixed rotary valve trays were measured and compared with those of rotary float valve trays and F1 valve trays. The results showed that the dry pressure drop of the fixed rotary valve trays was higher than that of the F1 valve trays while the kinetic energy factor got larger. The wet pressure drop of the fixed rotary valve trays was lower than those of the rotary float valve trays and F1valve trays. The entrainment of the fixed rotary valve trays was less than that of the F1 valve trays by 30%-40%and less than that of the rotary float valve trays by 10%-20%. According to the results of the CFD simulation,the performances of the fixed rotary valve trays were much better than those of the rotary float valve trays and F1 valve trays.关键词
