    摘要： An exhaust gas desulfurization system includes a spray pipe which is provided with a plurality of nozzles in the lengthwise direction and whose one end is closed and arranged horizontally in an absorption tower through which the exhaust gas passes vertically. Absorbent slurry is fed from the other end of the spray pipe and is injected upward from the nozzles, by which absorbent slurry is brought into contact with the exhaust gas to perform treatment in the absorption tower. The flow passage on the closed end side of the pipe is present in a shape such that the flow passage cross-sectional area decreases toward the closed end.

    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 is related to a wet gas process which would not require a spray pump, and which would allow the absorption liquid to be recovered smoothly even if the flow velocity of the gases entrained to the liquid should decrease. A wet gas processing apparatus in which the absorption liquid collected in the first liquid storage tank is sprayed in a specified direction (which may be upward, horizontal or downward) by a discharge unit consisting of spray nozzles (14) or the like in the absorption tower. The sprayed liquid is brought into contact with the exhaust gases which are conducted into the tower, and the targeted components of the gases are absorbed and removed. This processing apparatus is distinguished by the following. The first liquid storage tank for the absorption liquid comprises a pressure tank (11) which generates a pressurized gas in the space above the surface of the collected liquid (11a). The increased pressure of the pressurized gas is employed to spray the liquid collected in the pressurized tank from the spray nozzle unit in the absorption tower. This apparatus is further distinguished as the following. This invention has overflow ports which generate a virtually horizontal overflow or source flow. The absorption liquid propelled by the overflow ports makes orthogonal contact with the flow of exhaust gases, which results in both atomization of the liquid and liquid-vapor contact.

    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.
