| Abstract: |
| Based on the treatment technology of SO2 in ship flue gas, according to the flue gas flow rate and the concentration of SO2, this paper designed and calculated relevant parameters from four aspects, including the tower diameter, type and height of packing layer, number of liquid nozzles, and demister. Then this paper proposed specific parameters of seawater desulfurization absorption tower for ships under the condition of existing flue gas flow rate and sulfur content. At the same time, considering the variation of sulfur content in the flue gas, and ensuring that SO2 in the flue gas can be completely removed, the author set four rows of liquid nozzles. Through the finite element analysis software FLUENT, the start and stop modes of the nozzles under different sulfur content conditions were optimized according to the sulfur content at the outlet, pressure distribution and flow velocity distribution in the tower. |
