摘要： In an absorbing tower including an absorption unit of relatively small diameter capable of absorption and removal by an absorbent slurry for exhaust gas purification and a tank unit of relatively large diameter for temporarily storing the absorbent slurry flowing down from the absorption unit, the tank unit and the absorption unit are joined together by a conical member. By disposing an entrance flue at the conical member, a distance from an upper portion of the conical member to a spray header is shortened, and a height of the absorbing tower can be reduced accordingly. By extending a front end of the entrance flue to the absorption unit into which droplets of the absorbent slurry fall, a high-temperature exhaust gas from a boiler, etc., that has passed through the entrance flue, is made to pass through a circumference of the conical member so that an inexpensive material can be used in the conical member.

摘要： An absorbing tower is provided in its side wall with a gas entrance for introducing a combustion exhaust gas into the absorbing tower, and an absorbing liquid is sprayed from the nozzles of a spray header into the exhaust gas introduced to rise from the gas entrance. A trough is arranged in the side wall of the absorbing tower and above the gas entrance, and a nose having a horseshoe shape in a top plan view and extending into tower is disposed in the tower side wall portion of the gas entrance other than the portion arranging the trough and at the same or at substantially the same height as the portion of the trough. The absorbing liquid, which is sprayed from the nozzle and drops along the absorbing tower wall portion, is rescattered to the center portion of the absorbing tower excepting the entrance of the absorbing tower, so that the gas-liquid contact efficiency is improved while suppressing an increase in pressure loss, thereby to prevent the drift of the gas at the tower wall portion.

摘要： An elongated absorber housing, including an inlet duct and an outlet duct, is integrally provided on an upper portion of a circulation tank. The absorber is a self-supporting structure supported by only the circulation tank. At least the furthest upstream spraying stage in a spraying zone in the inlet duct includes spray pipes provided with spray nozzles for spraying an absorbing liquid in a direction cocurrent with gas flow, and at least the furthest downstream spraying stage includes spray nozzles for spraying the absorbing liquid in a direction countercurrent to the gas flow. The absorber is an integral structure in which the upper portion of the circulation tank forms a part of the duct, whereby the absorber is self-supportable and, moreover, is of a simple structure, giving it high strength and eliminating of the need for provision of fitments for supporting the absorber.

摘要： Flue gas of boiler is introduced through gas inlet part of flue-gas desulfurization apparatus, and absorbent liquid sprayed from spray nozzle is trapped in recirculation tank. There, agitation is performed by oxidation agitator to thereby oxidize SO2 absorbed from the flue gas into gypsum. In the tank, oxidation air is fed from posterior air pipe and anterior air pipe behind and ahead of liquid propulsion by the propeller. Thus, even when the amount of oxidation air must be increased in accordance with an increase of boiler load, the oxidation efficiency can be enhanced without increasing the number of agitators. Then the apparatus with which even when the amount of oxidation air fed to the liquid trapping section is increased, highly efficient oxidation can be performed without increasing the number of agitators installed and the operating cost.

摘要： A system is provided that prevents inhibition of adsorption of Hg and other heavy metals by activated carbon or other heavy metal adsorbent due to prior adsorption of sulfur trioxide (SO3) in an exhaust gas containing SO3. As it has been found that while SO3 is adsorbed, the adsorption of SO3 precedes the adsorption of Hg and other heavy metals onto activated carbon, a basic substance injection system is disposed along an exhaust gas flow channel at an upstream side of an activated carbon injection system, thereby attaining effective removal of Hg and other heavy metals from the exhaust gas by adsorption thereof onto surface pores of the activated carbon. The SO3 concentration after removal by basic substance conversion is computed from the SO3 concentration before removal, and the activated carbon injection rate can be controlled based on the concentration after removal.

摘要： Exhaust (Flue) gas of boiler is introduced through gas inlet part (port) (2) of flue-gas desulfurization apparatus (system), and absorbent liquid sprayed from spray nozzle (5) of absorbent liquid spray section (4) is trapped (stored) in liquid trapping (recirculation tank) section (7). There, agitation is performed by means of propeller (11) of oxidation agitator (8) to thereby oxidize SO2 absorbed from the exhaust (flue) gas into gypsum. In the liquid trapping section (7), oxidation air is fed from posterior air pipe (10) and anterior air pipe (13) behind and ahead of liquid propulsion (to the rear and front of a liquid discharge) by the propeller (11). Thus, even when the amount of oxidation air must be increased in accordance with an increase of boiler load, the oxidation efficiency can be enhanced without increasing of the number of agitators. Accordingly, there can be provided a wet flue-gas desulfurization apparatus (system) and method with which even when the amount of oxidation air fed to the liquid trapping section is increased, highly efficient oxidation can be performed without increasing the number of agitators installed and the operating cost.
