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： The gas-cleaning apparatus for a blast furnace operating under pressure using a differential-pressure washing arrangement whereby the differential-pressure washer comprises at least one annular gap with an annular-gap passage and an axially adjustable body received in the annular gap washer. The nozzle is disposed upstream of the annular-gap washer to spray the washing liquid into the gas which is accelerated through the annular gap. The position of this body is controlled in response to the gas pressure within the head of the blast furnace. The annular gap of the washer diverges in the direction of flow of the gas and the body has a complementary shape so that the gap width remains generally constant although its flow cross section increases with the diameter of the annular gap in the direction of flow of the gas.

摘要： A nonferrous metal is heated so as to produce a hot gas that is passed through an evaporative-cooler and, without saturation of the gas, is introduced into a dry-process filter where particulate material is removed. Thereafter this gas is fed to a scrubbing tower whose scrubbing liquid removes gaseous, liquid, and any remaining particulate material from the gas and exits from the tower as a scrubbing liquor. This liquor is clarified and the decantate is recirculated for use as the scrubbing liquid while the sludge is neutralized and sent back to the evaporative cooler. The neutralized sludge is flash evaporated in the evaporative cooler so as to form crystals that are removed from the system either in this cooler or at the dry filter downstream therefrom. A particle filter may be provided between the neutralizer and the evaporative cooler to remove any hard particulate material from the neutralized sludge.

摘要： Sodium carbonate is added to water used to scrub converter gases so that calcium-oxide particles in the gas react with the aqueous sodium carbonate and a thin inactive film of calcium carbonate is formed on the calcium-oxide particles, using carbon dioxide in the gas for the reaction. The coated particles are then separated from the wash water by settling and sedimentation and the wash water is recycled with the addition of more sodium carbonate and water.

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： Calcium sulfate dihydrate in large crystal form is produced by maintaining the circulation of the lime containing scrubbing solution in the desulfurization scrubbing of flue gases from a power plant boiler so that it has a residence time of 5 to 25 hours, preferably 15 hours. The crystals are moved by passing a portion of the recirculation through a thinner in which a sludge containing crystals with a mean particle size of which 90% is in excess of 100 microns is removed. This product can be dewatered and treated with sulfuric acid and steam to convert it to the alpha semihydrate and is free from sulfite.

摘要： A washer having a controlled-gap scrubber is connected to the gas outlet of a pressure blast furnace and an expansion turbine for the recovery of energy is connected downstream of the controlled-gap washer unit while a bypass is connected across the turbine. The system has operating regions A and B on a diagram in which the gas pressure is plotted along the ordinate and the volume rate of flow of gas from said blast furnace is plotted along the abscissa, the region A being defined between the turbine-insertion and the turbine-operating characteristic curves plotted on the diagram, the region B being defined between the turbine-operating characteristic curve and the corrected blast-furnace characteristic curve. The pressure in the blast furnace where the operating point is in region A while the gas traverses the turbine is controlled by varying the gap width of said control-gap washer unit in response to the pressure. The pressure in said blast furnace when the operating point is in the region B is controlled by varying the cross-section of the bypass valve, the gap of the washer being controlled in response to the differential pressure thereacross.

摘要： Dust-laden waste gases from a converter and from ancillary equipment are exhausted by respective blowers through a first and a second duct to a main and a secondary scrubbing station whence the purified gases escape through respective chimneys. The first duct is provided with two cascaded washing stages, the upstream stage being operable to throttle or block the flow of gases therethrough. An annular cowl for the interception of peripherally escaping converter gases is connected to a third duct which joins the first duct at a location between the two washing stages but is also connectable through a switching valve to the second duct. The switching valve is open in the blowing phase of the converter while a movable insert at the upstream washing stage unblocks the first duct; in the charging phase, the switching valve is closed and the insert at the upstream stage obstructs the first duct as the gases picked up by the cowl are drawn through the third duct and the downstream washing stage of the first duct for discharge through the chimney of the main scrubbing station.

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.
