Embodiment 3

[0068] Compared with other flue gas scrubbing devices, such as the packed tower, two-stage series spray tower, foam tower and bubble tower adopted by PureSOx, BELCO, Hamworthy and Ecosilencer respectively, the first three devices adopt hybrid system, and the last one adopts open The ring is the seawater desulfurization system. Their desulfurization rates are 99%, >97%, 99%, and 90%. Although good results have been achieved, the size of these tower equipment is about Φ5 m×10 m. The volume occupies a large amount of ship space, and the investment cost and operating cost are relatively high. The application number published in 2006 is 200810048002.2 and the name is "Sea-sea Ship Smoke Desulfurization Method and Device". Packed scrubbers are used for seawater desulfurization. Under the condition of 3% of the volume, it can reduce the emission of SO 2 When the sulfur content of the equivalent fuel oil is 0.1%, that is, the desulfurization rate reaches 96.7%. However, when the sulfu...

Abstract

The invention belongs to flue gas desulfurization and dust removal technology, in particular to a flue gas desulfurization and dust removal process and integrated device suitable for ships, which solves the problems existing in the existing ship flue gas desulfurization and dust removal process and equipment. Flue gas desulfurization and dust removal equipment, including multi-stage cross-flow rotary packed bed, lean liquid tank, lean liquid circulating pump, aeration tank, etc. The flue gas desulfurization process includes the open seawater flue gas desulfurization process and the closed alkali liquor flue gas desulfurization process. The two processes can be used in combination, and combined with the rotating packed bed, it has the advantages of high desulfurization rate, low energy consumption, simple process, low investment and operating costs, stable operation, convenient start and stop, and realizes the integration of desulfurization and dust removal.

Description

technical field [0001] The invention belongs to the technical field of flue gas desulfurization and dust removal, and in particular relates to a flue gas desulfurization and dust removal process and an integrated device suitable for ships. Background technique [0002] Ship power plant (large diesel engine) uses heavy oil with extremely high sulfur content, resulting in a large amount of SO in its exhaust x , causing serious air pollution. In order to control the pollution caused by marine diesel engine emissions, the International Maritime Organization (IMO) has revised the MARPOL73 / 78 Convention Annex VI "Regulations on the Prevention of Air Pollution from Ships", and the regulations on the content of marine fuel oil are more stringent: for sulfur oxides Emission control areas shall not exceed 0.1% from January 1, 2015; for non-control areas, starting from January 1, 2012, the sulfur content of global marine heavy fuel oil will be reduced from 4.5% in Annex VI to 3.5%. ...
