    摘要： For the purposes of solving a problem due to a fly ash and HF in an exhaust gas, maintaining the activity of calcium carbonate as an absorbent, and recovering a high-purity gypsum, there is here provided a method for desulfurizing an exhaust smoke which comprises the steps of leading the exhaust gas containing the fly ash to a gas absorbing step, removing SO.sub.2 and the fly ash from the exhaust gas by the use of an absorbing solution slurry containing calcium carbonate as an absorbent in the gas absorbing step, and blowing air into the absorbing solution slurry circulating through the gas absorbing step to oxidize it and to thereby produce the gypsum, the aforesaid method being characterized by drawing a portion of the absorbing solution slurry therefrom, leading it to a magnetic field to separate and recover the fly ash from the absorbing solution slurry, and then returning, to the gas absorbing step, a portion or all of the absorbing solution slurry from which the fly ash has been separated.

    摘要： In a wet lime desulfurization of exhaust gases containing SO.sub.2 and fly ash, a method and apparatus for treating absorbent solution slurry-containing fly ash includes diverting at least a part of the absorbent solution slurry containing fly ash particles, separating the diverted absorbent solution slurry by centrifugal separation into the solid gypsum component and a liquid component of a suspension containing fine fly ash particles, adjusting the pH value of the suspension containing fine fly ash particles remaining in a filtrate to 6 to 9 by adding an alkali, supplying the pH adjusted suspension to a thickener, removing concentrated sludge from the thickener, passing overflow H.sub.2 O from the thickener to a limestone slurry tank, and passing slurry from the limestone slurry tank to the absorbent solution slurry as make-up feed. Ill effects caused by fly ash and HF in exhaust gases are avoided, the activity of CaCo.sub.3 in the absorbent slurry is maintained, and highly pure gypsum is recovered.

    摘要： A wet exhaust gas desulfurization apparatus includes a housing, an absorbing solution (3, B) stored in the lower portion of the housing, a flue (1, 2, 11, 12, 21, 25) above the surface of the absorbing solution, and a partition plate (4, 15, 25) for dividing the flue into gas inlet and outlet portions. Exhaust gas is introduced as an untreated combustion gas from a space above an absorbing solution (3) divided by a partition plate (4) into the wet exhaust gas desulfurization apparatus, the lower edge (5) of the partition plate is immersed in the solution, pressure of the exhaust gas lowers the upper level (6) of the solution on the upper side of the plate to a level (6') through which the gas passes and flows under the partition plate in contact with the solution leaving the solution on the other side of the plate and then discharges through a space above the absorbing solution on the other side of the partition plate. The plate may be raised and lowered by a rack (4') and pinion ( 4") device, and water jet devices (29) may be used to wash absorbing solution off the surfaces (27, 28) of the plate continuously or intermittently.

    摘要： A solution or slurry containing a carbonate or sulfite, or both is continuously supplied into a tightly closed vessel, while any excess of the liquid is allowed to overflow the vessel. Sulfuric acid is supplied into the vessel to maintain the pH level of the liquid in the vessel at a value not exceeding 3. Air is supplied into the vessel as a carrier gas for CO.sub.2 or SO.sub.2 or both formed by the reaction of the carbonate or sulfite or both in the liquid with the sulfuric acid. The carrier gas is collected from the vessel, and the concentration of CO.sub.2 or SO.sub.2 or both in the carrier gas is determined. The concentration of the carbonate or sulfite or both in the liquid is obtained by calculations from the concentration of CO.sub.2 or SO.sub.2 or both, the flow rate of the liquid and the flow rate of the carrier gas.

    摘要： A slurry sampling device (3) for sampling a slurry in which solid particles are dispersed has upper and lower blocks (105, 109), and a rotator (102) for collection which is rotatably held between the blocks and has a plurality of through holes (111) each having a volume corresponding to the amount of sample to be collected. The upper and lower blocks are provided with slurry conduits (101, 108) and carrier fluid conduits (107, 110) which can be communicated with the through holes so that slurry and carrier fluid can flow therethrough. Arc-shaped long grooves (113, 114) are provided on portions of the upper and lower blocks where ends of the slurry conduits (101, 108) come into contact with, or are adjacent to, the rotator, so that at least one of the through holes is thereby constantly in contact with the long grooves. In the method for sampling slurry a part of the slurry is pumped (2) from a slurry tank (1) and returned (4) to the slurry tank, and that part of the slurry is sampled intermittently by the sampling device (3) and sent to an analyzer (6) for analysis of the composition of the slurry.
