Definitions

  • the invention relates to a device for the steel industry and a method for operating this device. To put it more precisely, it is about the operation of a pyrometallurgical treatment vessel for treating molten metal on the one hand under vacuum and on the other hand under atmospheric pressure.
  • the German Offenlegungsschrift DE 2 239 578 discloses a gas collection hood for collecting hot off-gases from a bottom blown oxy-steel converter vessel.
  • the hood has an adjusting ring that can be raised or lowered in order to be able to set an air gap between the converter mouth and the hood to a selectable value.
  • the hood is connected via a water-cooled flue or exhaust pipe to a first venturi scrubber for extinguishing and pre-cleaning the hot process exhaust gas.
  • An exhaust fan is installed downstream of the Venturi scrubber for exhausting the process off-gases from the converter. The characteristics of the exhaust fan can be adjusted within a wide range.
  • the pressure or the negative pressure in the converter can be variably adjusted as desired.
  • fresh air is sucked into the converter through the open air gap, which leads to post-combustion of the process exhaust gas and increases the required suction volume.
  • dusty exhaust gas can escape through the open air gap, which then either flows into the surrounding hall or has to be extracted through additional hoods.
  • EP 1 431 404 A1 also a device and a method for treating molten metal in a converter, alternatively either with an attached vacuum hood during vacuum operation or under atmospheric pressure.
  • the process gas from the converter is first routed through a gas cooler and then through a dust filter with the help of an exhaust gas line from the vacuum hood, before it then runs through a vacuum pump before it is discharged through a chimney into the ambient air.
  • the US patent U.S. 4,190,237A discloses a pyrometallurgical treatment vessel for treating a melt, the treatment vessel is housed in a gas-tight manner in a pressure vessel which is connected gas-tight to an exhaust hood and exhaust pipe for the treatment vessel.
  • An exhaust diverter is provided in the exhaust pipe for directing the exhaust gas selectively to a chimney when the CO content of the exhaust gas is low, or to a gas storage tank when the CO content in the exhaust gas is high.
  • the invention is based on the object of further developing a known device for treating molten metal and a known method for operating the device under atmospheric pressure such that the same device can alternatively also be operated under vacuum and that the total treatment time for both operating modes is shortened and the dust or Process gas emissions into the environment are reduced or prevented during the entire treatment time.
  • hood is placed gas-tight as a vacuum hood on the treatment vessel; that the exhaust pipe leads from the vacuum hood; that a vacuum pump is provided in the exhaust line for generating the vacuum under the vacuum hood in the pyrometallurgical treatment vessel; that the exhaust diverter - viewed in the direction of flow of the exhaust gas - is installed in the exhaust pipe before the vacuum pump; and that the exhaust diverter is designed to divert the process gases either through the vacuum pump for treating the molten metal in the pyrometallurgical treatment vessel under vacuum or through the suction fan.
  • pyrometallurgical treatment vessel means in particular a converter.
  • the vacuum hood is placed on the pyrometallurgical treatment vessel in a gas-tight manner not only during vacuum operation, but also during operation of the pyrometallurgical treatment vessel under atmospheric pressure. This ensures that no process gases, in particular no dust and no flue gas, can escape from the pyrometallurgical treatment vessel into the environment during the two operating modes and in the meantime or during a change between these two operating modes. There is no time delay when changing the two operating modes (atmosphere-vacuum) by changing the vacuum hood and suction hood, as was sometimes necessary in the prior art.
  • no additional hood is required because of the hood that may be permanently attached to prevent any process gas escaping during the two operating modes suck off.
  • the amount of waste gas is reduced compared to the prior art because there is no post-combustion with the ambient air behind the mouth of the pyrometallurgical treatment vessel.
  • the vacuum seal between the vacuum hood and the pyrometallurgical treatment vessel does not need to be separately protected during atmospheric treatment.
  • the fact that the vacuum hood and the pyrometallurgical treatment vessel form a closed system according to the invention effectively prevents dust-containing swells from escaping through an existing or open air gap between the pyrometallurgical treatment vessel and the hood and thus contamination of the pyrometallurgical treatment vessel and the hood.
  • the vacuum pump is designed to lower the air pressure in the pyrometallurgical treatment vessel for treating the melt under vacuum to below 300 mbar, preferably at least temporarily to below 50 mbar.
  • the pressure difference of the exhaust fan is much lower; if at all, it is only slightly below atmospheric pressure.
  • the exhaust fan absorbs the process gases - comparable to an extractor hood over a stove - under atmospheric pressure and forwards them to the chimney or the gas extraction device.
  • the entire exhaust gas path from the pyrometallurgical treatment vessel to the chimney or to the gas extraction device is essentially under atmospheric pressure during atmospheric pressure operation.
  • the claimed device there is only one exhaust gas line, which leads the process exhaust gas from the pyrometallurgical treatment vessel to the exhaust gas diverter according to the invention, from where the process gas is then routed either through the vacuum pump or through the exhaust fan.
  • An exhaust gas cooler and/or an exhaust gas filter can be arranged in front of the exhaust gas diverter be. Both the exhaust gas cooler and the exhaust gas filter are optionally advantageously used for both operating modes.
  • an oxygen lance is also possible in the device according to the invention for both operating modes if the oxygen lance is sealed with a vacuum-tight seal relative to the vacuum hood through which it is immersed in the pyrometallurgical treatment vessel.
  • Material can be added batchwise or continuously via a material feed device, but the material feed device must be sealed off from the interior of the pyrometallurgical treatment vessel by a vacuum lock. Because the hood no longer has to be moved or changed, the housing of the hoods, ie the so-called doghouse, can be made smaller or more space-saving than in the prior art.
  • a gas extraction device can be connected downstream of the vacuum pump or the exhaust gas fan, as a result of which the CO 2 balance is improved. The provision of the gas extraction device makes sense because the process gas sucked out of the pyrometallurgical treatment vessel contains carbon monoxide CO.
  • the above object of the invention is further achieved by a method for operating the device.
  • the advantages of this method correspond to the advantages mentioned above in relation to the device.
  • the figure shows the device 100 according to the invention. It essentially comprises a pyrometallurgical treatment vessel 110 with an airtight hood 120 for treating molten metal.
  • a material feeder 125 can be seen for feeding feedstock or additives into the pyrometallurgical treatment vessel.
  • the device or the pyrometallurgical treatment vessel can be operated either in a vacuum operation mode or in an atmospheric pressure operation mode.
  • the material feed device 125 is sealed at the point where it enters the pyrometallurgical treatment vessel 110 or the hood 120, so that in the case of vacuum operation no extraneous air can be sucked in through this inlet opening.
  • Floor nozzles 115 can be provided in the bottom area of the pyrometallurgical treatment vessel and/or an oxygen lance 118 can be provided, which can be guided through the hood into the interior of the pyrometallurgical treatment vessel.
  • the oxygen lance may also have to be sealed airtight or vacuum-tight against the hood in the area where it enters the vacuum hood 120 .
  • the process gases from the pyrometallurgical treatment vessel 110 are discharged from the pyrometallurgical treatment vessel 110 in the direction of the arrow via an exhaust gas line 130 which is typically connected to the hood 120 .
  • the process gas preferably first passes through a gas cooler 140 and an exhaust gas filter 150.
  • an exhaust gas diverter 135 is connected downstream of the filter 150 for selectively diverting the process gas either through a vacuum pump 160 for said vacuum operation or through an exhaust fan 170 for said atmospheric pressure operation .
  • the outputs of the vacuum pump and the exhaust fan 170 can turn to one Exhaust line brought together and a chimney 180 and / or a gas extraction device 190 are fed.
