Abstract Scope |
The efficient separation of fine particles from industrial flue gas is still a challenging task. Reverse spray washing technology is gradually used in dust removal due to its advantages of simple structure and large interphase contacting area. In this paper, the lab-scale reverse spray washing device was established. The changes of gas-liquid two-phase flow pattern, pressure drop and structure characteristics under different operating conditions were studied. It was found that four types flow regimes, hollow tapered, foaming, annular and column types, will form. The foaming type has fast surface renewal speed and large contacting area, which is more conducive to the removal of fine particles in the flue gas. The operation and performance diagram of the nozzle was drawn. The formation of different flow patterns can be controlled by controlling the ratio of liquid to gas and the axial and tangential liquid flow ratio of the nozzle. |
