摘要： A wet flue-gas desulfurization system which effectively reduces the mist concentration in the treated gas at its outlet. The system includes an absorption column, formed with a tank at the bottom which is supplied with an absorbent slurry and a circulating pump for forcing the slurry upwardly from the tank into the flue gas inlet at the top of the column for contact with flue gas. Sulfur dioxide, for example, is removed from the flue gas, being introduced in the flue gas inlet, by absorption with the absorbent slurry. The treated gas, free of sulfur dioxide, is discharged through a gas-outlet duct formed to rise integrally from the top of an end part of the tank. For reducing the mist concentration a mist eliminator is provided and is held upright, as a vertical partition, across the riser of the duct, with the lower end of the eliminator being extended partly into the bath of the absorbent slurry inside the tank.

摘要： Flue gas is treated for the presence of SO.sub.3, without resorting to ammonia injection, by adding a powder into the flue gas and subsequently bringing the flue gas into gas-liquid contact with an absorbing fluid, whereby the SO.sub.2 present in the flue gas is removed by absorption into the absorbing fluid. The treatment process may also include introducing the flue gas into a dust collector, whereby dust, including the powder present in the flue gas, is collected, and/or recovering heat from the flue gas by means of a heat exchanger, whereby the flue gas is cooled. A system for treating flue gas is also provided.

摘要： This invention relates to a flue gas treating process including a heat recovery step for recovering heat from flue gas by means of a heat exchanger (4) and thereby cooling the flue gas, and a subsequent absorption step for bringing the flue gas into gas-liquid contact with an absorbing fluid (D) in absorption towers (12, 13) so as to remove at least SO2 present in the flue gas by absorption into the absorbing fluid (D), which is characterized, for example, in that a powder addition step for spraying a powder collectable in the absorption step into the flue gas is provided prior to the heat recovery step. This invention makes it possible to provide a flue gas treating process in which a countermeasure against SO3 present in flue gas can be easily achieved without resorting to ammonia injection and the flue gas can further be purified without the disadvantage of causing the injected substance to remain in the treated flue gas.

摘要： This invention relates to a flue gas treating system including a desulfurization apparatus for bringing flue gas into contact with a calcium compound-containing slurry so as to cause sulfur dioxide present in the flue gas to be absorbed into the slurry, oxidizing the slurry having undergone contact with flue gas, and subjecting the oxidized slurry to solid-liquid separation so as to obtain gypsum as a by-product; a waste water treating apparatus for treating part of a first filtrate produced during solid-liquid separation of the slurry having undergone contact with flue gas in the desulfurization apparatus; and solid-liquid separation device for subjecting sludge produced in the waste water treating apparatus to solid-liquid separation independently of the slurry having undergone contact with flue gas, wherein a solid material separated from the sludge by the solid-liquid separation device is incorporated into the gypsum and all of a second filtrate produced during solid-liquid separation of the sludge by the solid-liquid separation device is introduced into the waste water treating apparatus together with part of the first filtrate. In this system, the dumping disposal of sludge produced in the waste water treating apparatus is not required and the concentration of impurities in the absorbent slurry within the desulfurization apparatus can be kept on a low level.
