摘要： An apparatus for cleaning the exhaust gas of a high-pressure blast furnace comprises a coarse-particle separator, a prewasher and a differential-pressure annular gap washer traversed in succession by the gases. The exhaust gases can be passed through a main duct provided with an expansion turbine or through a bypass duct around the expansion turbine. The expansion turbine unit controls the back pressure at the blast furnace while a separate control circuit is provided to operate the differential-pressure washer with optimum efficiency. A quick-closing valve in the turbine-supply line and a quick-opening valve in the bypass line permits rapid switchover, a pressure-control valve in the bypass line maintains a constant backpressure at the blast furnace when the expansion turbine unit is shut down.

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： An annular gap washer for scrubbing a gas stream with a liquid, especially for the scrubbing of blast furnace gases with water such that the adjustment of the width of the annular gap controls the pressure at the head of the blast furnace, comprises the usual housing or duct with a tapering configuration and a body axially movable in this duct and with a tapering configuration so that the annular gap is formed between this body and the duct wall. According to the invention, the base angles of the body and the duct walls are different such that the gap converges in the direction of flow of the gases, thereby reducing vibrations or oscillation of the body without interfering with scrubbing efficiency.

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： Converter exhaust gases in a steel-refining plant are used for the recovery of energy, e.g. for the production of electrical energy. The steel-refining process is carried out in a closed converter maintained at a pressure of from 1 to several atmospheres gauge above ambient pressure. The converter exhaust gases at such elevated pressure is subjected to washing, preferably in the exhaust-gas stack or duct and the washed converter exhaust gases from several refining processes is stored and supplied to a gas consumer, e.g. an electrical generating plant, at a rate which is independent of the blowing period.
