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： A flue gas treating system for removing sulfur dioxide and dust present in flue gas by gas-liquid contact with an absorbing fluid and has an inlet side absorption tower of the liquid column type and an outlet side absorption tower of the liquid column type, each of which has a uniform cross-section over the area of gas-liquid contact, and the cross-section of flue gas in the inlet side absorption tower is smaller than the cross section of flue gas in the outlet side absorption tower. The inlet side absorption tower is constructed in the form of a parallel-flow absorption tower wherein the flue gas flows downward for favorable collection of dust and absorption of sulfur dioxide. The outlet side absorption tower is constructed in the form of a counter-flow adsorption tower wherein the flue gas flows upward for favorable absorption of sulfur dioxide. The absorbing fluid within a tank is injected upward from a plurality of spray pipes.
