摘要： A scrubbing column for flue gases and especially power plant flue gases removes sulfur oxides by absorption in a calcium containing scrubbing liquid and is surmounted by a water separator which is subdivided into sectors readily traversed by the flue gas at the head of the column and around a central plenum. The passage around these sectors, which is connected with a radially offset flue gas outlet, has a cross section progressively increasing toward this outlet.

摘要： Swirl nozzles, especially for plants with flue gas scrubbers for the physical and/or chemical purification of flue gases emanating from power plant boiler installations. The nozzles include a substantially cylindrical nozzle chamber, at least one tangential scrubber fluid inlet into the nozzle chamber, and at least one nozzle bore arranged in a nozzle chamber bottom and extending coaxially with its axis with respect to the nozzle chamber. A conduit for feeding scrubber fluid can be secured at the tangential scrubber fluid inlet, and this conduit carries the swirl nozzle apparatus. The nozzle chamber and the inlet are provided in a body made of ceramic wear material, with the respective ends of the chamber also made of ceramic wear material and connected to the body. At least one chamber bottom includes the nozzle bore. The body and the nozzle chamber bottoms are arranged between steel stress plates. At least the body can be held under pretension condition between these stress plates. One of the stress plates includes an aperture at which can follow the scrubber fluid inlet, and it is also equipped with a short connecting pipe for the conduit for feeding a scrubber fluid.

摘要： A cylindrical scrubbing column having a cylindrical water-separator head is provided with an upwardly converging partition defining a diametrically extending elongated slot which communicates between the scrubbing region of the column and the head, the slot being aligned with a radial outlet for the flue gases from the head. The slot is flanked by a pair of longitudinally-extending impingement baffle register walls which remove water from the entraining flue gas by impingement baffle separation techniques and a further wall is provided at the end of the slot turned toward the radial outlet. The walls can converge in the direction of flow of the gas upwardly and the compartments behind the walls communicate with the radial outlet. The system has reduced pressure drop without detrimental effect to the separating efficiency.

摘要： A scrubber for the desulfurization of flue gases in which the flue gas rises through the recirculated scrubbing liquid which can contain calcium compounds, has a liquid separator at the head of the column formed by a number of impingement baffle registers or units in an annular array. The gas collecting passage surrounding this array is provided with flaps or sliders as closure elements to isolate at least one segment of this passage and thereby accommodating the scrubbing to less than full gas loading.

摘要： A scrubber is provided with a grate in its sump through which oxygen is introduced to separate the oxidation zone above this grate from a reaction zone below the grate, a calcium containing additive being introduced into this reaction zone. Flue gas to be desulfurized is passed through a washing zone above the sump and there contacted with normally circulating scrubbing liquid containing the additive to absorb sulfur dioxide and sulfur trioxide. The sulfur dioxide is oxidized to sulfur trioxide and the additive induces precipitation of calcium sulfate in the sump. After a prolonged standstill, settled solids in the sump are induced into movement by drawing a portion of the sump liquid from an upper part thereof and injecting it into a lower part of the sump.

摘要： A scrubber for desulfurization of gases, in particular flue gases of a boiler furnace includes two scrubbing zones each having a plurality of spaced arrays of nozzles for washing the gas with a respective washing liquid containing sulfur compound binding additives. At the bottom portion of the scrubber, the liquid discharged from the nozzles and containing sulfur compounds forms a sump to which limestone is added. From the sump two circulation systems extend. Each circulation system includes a pump which draws off a respective washing liquid from the sump and conveys the latter to the associated one of the scrubbing zones whereby whitewash or lime milk is introduced into one of the circulation systems.

摘要： A suspension of sulfur in a scrubbing liquid is preheated with steam to a temperature above the melting point of the sulfur so that the latter spontaneously melts in the suspension which is introduced into a separating chamber in a sealed vessel. The scrubbing liquid is decanted over a weir into a second chamber while the molten sulfur is drawn out at the bottom into a third chamber. The separating chamber is maintained at a pressure and temperature, by a vapor cushion above the liquid, such that evaporation of the incoming liquid does not occur, i.e. the separation pressure is the saturation pressure of the cushion. To prevent vapor condensation on the molten sulfur, the latter is maintained at a temperature higher than that of the liquid in the adjacent separating chamber.
