(Continued from page 6) (2) When the other operating parameters constant, the pressure and the pressure loss increases with the flow. To better the separation, cyclone underflow need for proper back pressure. (3) vortex cavity and the cone section of the pressure loss,[link widoczny dla zalogowanych], followed by the population segment, while the cylindrical tail pipe section of minimum pressure loss. Cyclone separation section of the effective pressure loss in the cyclone chamber, not at the entrance. Pressure loss of each segment (especially the entrance), make full use of effective pressure loss and reduce the pressure loss is invalid, the future of the important issues to increase. (4) found that, rationalize cyclone structure and can improve the separation efficiency,[link widoczny dla zalogowanych], reduce the total pressure loss; reasonable control of the inlet pressure to reduce the pressure increment, and access to higher separation efficiency.
