초록
A scrubber is a typical piece of equipment used to reduce the amount of sulfur oxides emitted from marine engines. Many different types of scrubbers have been studied. In this research, the influence of two different types of scrubber structures on backpressure and flow streamlines was studied. Backpressure is closely related to the power and efficiency of the engine, and the behavior of the flow streamlines is related to the duration for which the exhaust gas and cleaning water are in contact. The length and number of horizontal and vertical baffles were calculated and analyzed. The result showed that an inner structure with a baffle length ratio of 0.6 with two baffles was considered optimal in the case of a horizontal scrubber, whereas a baffle length ratio of 0.7 with two baffles was considered optimal in the case of a vertical scrubber.
