摘要： PROBLEM TO BE SOLVED: To prevent the deposition of solid substances at the outlet of an absorption tower without increasing the height of the absorption tower. SOLUTION: At the bottom of an outlet section 50 of an absorption tower for absorbing and removing soot and dust or sulfur oxides contained in a combustion flue gas of a boiler, etc., with an absorbent liquid comprising an absorbent slurry containing limestone, lime, or the like, a downward inclined part is formed along a gas flow 51 in the outlet section 50. When a mist 60 containing solid substances falling down on the bottom becomes an absorption tower outlet drain 52 and returns to the absorption tower 4, the direction of the gas flow 51 and that of the absorption tower outlet drain flow 53 are the same, facilitating the flow of the drain 52 and thus making the deposition of solid substances on the bottom of the outlet section 50 difficult. Since the inclined part of the bottom of the outlet section 50 is downward inclined along the gas flow 51, the absorption tower 4 is not required to be high in height.

摘要： PROBLEM TO BE SOLVED: To obtain the stable operation of a desulturizing device by accelerating the oxidation and neutralization reaction of an absorbent solution and preventing the settling of the solid such as gypsum by eliminating the dead space of slurry agitation at a rectangular liquid reservoir. SOLUTION: The flow for sweeping the absorbent solution to the direction from a slurry agitator 11 to a discharge piping 12 of a circulation pump 6 is generated and moreover the solution is made to flow to the circulation pump 6 direction by the draw-in force resulted from the suction of the solution by the circulation pump 6 by arranging the slurry agitator 11 at the position at which the sweeping direction of the absorbent solution from the agitator 11 is placed oppositly to a discharge piping 12 of the circulation pump at the liquid reservoir 7 provided at the lower part of a absorption tower body 1 having a rectangular horizontal section. Therefore, a dwelling part of the solution is hardly caused at the liquid reservoir 7, especially bottom part, and the solid matter such as gypsum is hardly caused. In such a way, the pH of the absorbent solution becomes liable to recover since the retention time of the limestone supplied to the liquid reservoir 7 at the liquid reservoir 7 is increased.

摘要： PROBLEM TO BE SOLVED: To provide an economical flue gas treating equipment by using only one drain tank with a heat exchanger. SOLUTION: This processor comprises a GGH heat recovery unit 4 for recovering the heat of exhaust gas discharged from a burner, a desulphurization unit for removing SOx in the exhaust gas at the outlet of the GGH heat recovery unit 4, an SGH 50 for heating the exhaust gas at the outlet of the desulphurization unit with steam and a GGH reheating unit 8 for reheating the exhaust gas at the outlet of the desulphurization unit, wherein these components are sequentially arranged on an exhaust gas channel. The processor further comprises heat transfer tubes 11 and 12 respectively provided in the GGH heat recovery unit 4 and the GGH reheating unit 8 which tubes are communicated with each other, and heating medium circulation lines 13-1 and 13-2 provided with a heating-medium heater 17 for heating the heating medium therein with steam. In this case, drain from the heating-medium heater 17 is pressurized by a heating-medium heater drain recovery pump 57 and is led to an SGH drain tank 54 provided with a heat exchanger through a heating-medium heater drain recovery tank 56. As a result, it is possible to omit the installation of the heating- medium heater drain recovery tank with an expensive heat exchanger.

摘要： PROBLEM TO BE SOLVED: To establish a method for removing dust by maintaining heat transfer performance of a gas-gas heater(GGH) heat transfer tube group constant at the time of starting steel ball scattering and suppressing rise of smoke soot concentration in primary GGH. SOLUTION: A heat transfer tube group 5 of a gas-gas heater(GGH) heat recovering unit is divided into a plurality of blocks, a steel ball scattering time per one block is formed in an A pattern of a short time and the other pattern is formed in a B pattern of a long time to sequentially control to scatter the balls in one block of the divided blocks. The balls are scattered from above the group 5 disposed at an exhaust gas channel of a combustion equipment outlet of a boiler by this combination to remove smoke soots. The soots adhered to all areas of the group 5 are roughly removed in the A pattern, and the balls are scattered in an important manner in each block by the B pattern to remove the dusts, thereby suppressing rise of the soot concentration in the gas of a GGH rear stream side at the time of starting scattering of the balls. Since the soot amount adhered to the entire area of the group 5 can be reduced by the roughly removing by the A pattern scattering, pressure loss can be decreased, and heat transfer performance can be stabilized.

摘要： PURPOSE: To provide an economical wet flue gas desulfurizer and a desufurizing method in which by replenishment using various waste water or the like for making up for a shortage of water of a liquid absorbent, desulfurizing performance is not lowered. CONSTITUTION: It is necessary that the concentration of dissolved oxygen in a liquid absorbent in a circulating tank 6 delivered from a liquid absorbent pump 5 to a desulfurizing column body 1 is heightened. But, when the oil content in the makeup water in the liquid absorbent increases, the concentration of dissolved oxygen is lowered to adversely affect desulfurizing performance, so the oil content in waste water F which is makeup water is removed in advance. Or, since the oil content concentration and the dissolved oxygen concentration in the liquid absorbent are correlated to each other, the feed quantity of the waste water F contg. the oil content which is makeup water is restricted based on the measured value of the dissolved oxygen concentration of the liquid absorbent (by a dissolved oxygen concentration meter 18), allowing the desulfurizing performance to be increased.
