Abstract

The invention discloses a ship desulfurizing and dedusting system and belongs to the technical field of ship flue gas desulfurization. The system comprises a flue gas pipeline, a dedusting fan and a chimney in sequential connection, the upstream position of the flue gas pipeline is connected with a desulfurizer conveying unit while the downstream position of the same is provided with a dedusting unit, the desulfurizer conveying unit comprises an unpacking station, a mill, a middle bin and a powder conveyor in sequential connection, an output pipeline of the powder conveyor is connected with the flue gas pipeline, and an ejection device is arranged at the tail end of the output pipeline. The system is compact, convenient in operation and maintenance, little in one-time investment, small inoccupied area and low in running cost; the system is a completely-dry system and does not need water, thereby being less prone to causing secondary pollution; byproducts generated after gas-solid separation is performed on flue gas by a deduster can be used for industrial recycling like cement, glass, chemical industry, papermaking, dye and printing and dyeing; the system is high in desulfurizingefficiency and dedusting efficiency and completely meets technical requirements of domestic and international environment protection on sulfur dioxide emission.

Description

technical field [0001] The invention relates to the technical field of ship flue gas desulfurization, in particular to a ship desulfurization and dust removal system. Background technique [0002] At present, in the field of ship flue gas desulfurization, only the seawater scrubbing desulfurization process is widely used, but the disadvantages are also very prominent. Due to the limited space available on the ship, there is no effective pre-dust removal equipment at the front end of the desulfurization tower on the ship, the particulate matter exceeds the standard, the particulate matter dust is discharged, and the wastewater generated after desulfurization is likely to cause secondary pollution. With the promulgation of the sulfur limit order, countries around the world will gradually implement more stringent environmental standards. The current seawater desulfurization method will face the risk of overall transformation or secondary investment. The desulfurization tower s...
