Definitions

  • the invention relates to a method for operating a cooling chamber in a strand guide device of a continuous casting plant for casting a casting strand, in particular made of metal.
  • the invention relates to the strand guide device having a cooling device with the cooling chamber.
  • FIG. 5 shows the continuous casting system 100 disclosed there, in which a metal casting strand 13, for example, is cast with the aid of a mold 40 and is subsequently deflected horizontally with the aid of a strand guide device 10. It is also known that the casting strand that has not yet solidified, for example made of steel, has a plurality of cooling chambers 1, 1' within the strand guide device Figure 6 passes through, in which the casting strand 13 is cooled by spraying with a coolant 33 to form steam 5.
  • the steam is at least partially saturated with the coolant and is typically sucked out of the respective cooling chamber 1, 1' laterally, ie transversely to the pouring direction, with the aid of a suction device 20 individually assigned to each cooling chamber.
  • the suction device 20 has an induced draft fan 8, a suction opening 3 in a side wall of the cooling chamber 1, 1 'and a suction channel 7 connecting the suction opening and the induced draft fan 8.
  • different cooling strategies are used, i.e. different amounts of water are applied to the casting strand at different positions within the continuous casting system.
  • the amount of water applied locally depends on the desired cooling effect, on the speed of the casting strand within the strand guide device, on the cooling water temperature and/or on the temperature of the casting strand. It happens again and again that very little or even no water is applied to the lower areas of the strand guide, i.e. there is practically no cooling there. In these cases, the suction devices only suck in dry air from the cooling chambers there. Pre-cleaning of a steam-air mixture in the respective cooling chamber is not possible in this way.
  • the German disclosure document DE 10 2015 209 399 A1 discloses a device for removing exhaust air from the environment of a metal strand using a suction device.
  • the suction device is arranged on one side of the conveying section of the casting strand.
  • a fan is arranged to generate an air flow to convey the exhaust air in a blowing direction transverse to the conveyor path, as far as possible into the suction device.
  • a control device is used to adjust the delivery rate of the blower and the suction device depending on a measured speed of the metal strip.
  • the air particles of the exhaust air can be sucked out with significantly less air volume flow and therefore with significantly less energy expenditure than if the air volume flow had to be sucked in through the suction device alone.
  • the suction device is followed by an exhaust air treatment system for cleaning the exhaust air sucked in by the suction device, in particular for filtering out airborne substances from the exhaust air.
  • German patent specification discloses DE 10 2006 045 791 B4 a method and an arrangement for reducing pollutant emissions in the exhaust air of a rolling mill.
  • the method provides a condensation step in which part of the exhaust air passes from the gas phase to the liquid phase with the formation of droplets, and a particle separation step in which the droplets formed in the condensation step are separated.
  • the condensation step takes place in a condenser, which is designed as a heat exchanger.
  • parts of the exhaust air flow can be returned to the rolling mill.
  • Pre-cooled outside air can be supplied to the heat exchanger to promote the condensation step.
  • the process is primarily intended to be used in a cold rolling mill.
  • the invention is based on the object of developing a known method for operating a cooling chamber in a strand guiding device and the known strand guiding device itself in such a way that emission-relevant substances are removed from the steam-air mixture (5 ⁇ ).
  • Substances that are particularly relevant to emissions are those that are harmful to people and the environment, but also to machines, and limit values are often set for their proportions in the air.
  • the method is characterized in that the steam-air mixture is depleted using at least one separator, in particular by condensation.
  • the steam-air mixture is passed through at least one separator, which depletes the steam-air mixture in terms of its dirt and pollutant load, for example through condensation.
  • the separator is designed to cool the steam-air mixture, preferably adiabatically, and at the same time to remove moisture from it. According to the invention, this is done in that the moisture is condensed out of the sucked-in steam-air mixture using the separator.
  • the separator is also designed to significantly reduce the pollutant load in the vapor-air mixture. Pollutants such as “dust”, “fine dust” and “VOC (highly volatile organic substances)” accumulate on the condensed particles in the air during condensation and are removed together with them via a sewer and sent for appropriate post-treatment.
  • Pollutants such as “dust”, “fine dust” and “VOC (highly volatile organic substances)” accumulate on the condensed particles in the air during condensation and are removed together with them via a sewer and sent for appropriate post-treatment.
  • the separator is reduced to the “condensing” functionality described, it is also referred to as a capacitor for simplicity.
  • the separator preferably also has further functionalities for depleting pollutants in the vapor-air mixture.
  • the separator can be designed to implement only one, several or all of its functionalities described below in succession or simultaneously.
  • this depletion of pollutants succeeds so well that specified emission limit values can be safely adhered to.
  • the false air is extracted from the hall surrounding the strand guide device and is usually very heavily contaminated or contaminated, in particular with substances that are harmful to health.
  • the separator is arranged in front of the suction opening of the suction device in the cooling chamber.
  • the separator can also be installed in the suction channel of the suction device, which connects the suction opening and an induced draft fan of the suction device to one another.
  • the arrangement of the separator must ensure that the condensate is removed in the suction channel.
  • the “additional separator” is basically designed to implement the same functionalities as the separator.
  • the steam-air mixture can be additionally depleted by means of attachments and installations in front of, on or in the induced draft fan of the suction device.
  • the attachments and fixtures refer to installations, e.g. in the form of spray nozzles and/or specially positioned impeller blades of the induced draft fan, which lead to a reduction in emissions.
  • medium mainly water
  • the suction-draft blower also functions as a centrifugal separator for the pollutants in question.
  • the separator, the further separator and/or the attachments and installations each precondition the steam-air mixture extracted from the cooling chamber before it is released into the environment either via a chimney after passing through the suction-draft fan (according to the invention not favored) or is returned to the cooling chamber.
  • the reduction of the pollutant load in the steam-air mixture according to the first to fourth exemplary embodiments is also referred to as preconditioning.
  • the method according to the invention provides that additional air is supplied with the aid of a Pressure blower is blown into the cooling chamber.
  • additional air is supplied with the aid of a Pressure blower is blown into the cooling chamber.
  • the additional air supplied is therefore part of the steam-air mixture alongside the steam and the sucked-in false air.
  • the additional air supplied can either be fresh air drawn in from outside the hall in which the strand guide device is operated (1st variant) and/or air extracted from the hall (2nd variant). In the two variants, a more or less complex conditioning of the sucked in air may be required before it is fed or returned to the cooling chamber, depending in particular on its respective preload with pollutants.
  • a first possibility for conditioning the supplied air, in particular the fresh air sucked in is to change or adjust its temperature and/or its humidity in such a way that when it is mixed with the steam-air mixture already in the cooling chamber, the resulting mixture a desired target temperature and/or a desired target humidity is set.
  • Regional or seasonal weather differences change the formation of condensation in the cooling chamber.
  • a major problem here is the suction of so-called false air through unavoidable inlet and outlet openings in the cooling chamber in addition to the additional air supplied in a controlled manner. Unlike the variable, adjustable additional air, the false air is always sucked in due to the design.
  • the false air that is involuntarily sucked in is classified as containing more pollutants (mainly dust) than the additional air.
  • the false air is always part of the steam-air mixture in the cooling chamber. It would be advantageous to have a mean cooling chamber target temperature that is as constant as possible in the range of preferably 40 ° C to 60 ° C and / or a relative target air humidity of over 80%.
  • the target temperature of the resulting steam-air mixture can be set via the targeted inflow of a defined amount of additional air with a correspondingly selected temperature. Likewise, by appropriately adjusting the humidity of the additional air, the desired relative target air humidity can be set for the resulting steam-air mixture in the cooling chamber.
  • the conditioning of the additional air in the form of the air returned from the cooling chamber can be done by depleting it by adding separating agents to dissolve foreign substances from the steam-air mixture.
  • the steam is essentially generated by the coolant, mainly water, evaporating when it is applied to the still hot casting strand.
  • the coolant residues of casting powder and lubricants, e.g. B. oils and fats, which are required for the operation of certain system parts, for example for the segment rollers, get into the steam-air mixture. Due to contact with the hot casting strand and the associated evaporation process, portions of the substances mentioned can undesirably be found in the steam-air mixture.
  • separating agents provided according to the invention, So-called adsorbents, these substances can be dissolved again from the steam-air mixture and, if necessary, collected separately. Analogous conditioning can also be carried out for the additional air extracted from the hall.
  • the coolant that is used as part of said secondary cooling in the cooling chambers of the strand guide device to cool the casting strand typically consists of 100% water.
  • the dimensioning of the entire suction device i.e. H. of the induced draft fan, the suction duct and the suction opening are lower. This applies because the compressed air blower supplies large quantities of the steam-air mixture to the suction opening, which was previously, i.e. H. without the presence of the pressure fan, would have to be sucked in by the suction device alone. Reducing the size of the suction device also has the advantage that the volume flow of the steam-air mixture at the outlet of the suction device and thus the necessary power consumption of the suction device is reduced in the present invention.
  • Reducing the dimensions of the suction device also has the advantage that installation space can be saved and that assembly is made easier in tight spaces.
  • the reduced volume flow in the cooling chamber and the suction device favors the installation of the separator in front of the suction opening because the separator can be operated more effectively at low air speeds, ie with lower energy consumption.
  • the reduced volume flow from the cooling chamber advantageously also means that less false air is sucked in.
  • part of the extracted and pre-condensed steam-air mixture at the outlet of the suction device can advantageously be fed back to the cooling chamber via a first partial air return line, keyword endless filtration.
  • the remaining steam-air mixture which is released into the environment via leaks in pipes and ducts and/or ultimately via the chimney (not favored by the present invention), is reduced accordingly.
  • the invention provides that the steam-air mixture extracted from the cooling chamber is not discharged to the environment via the continued exhaust air duct via the chimney, but with a variably adjustable first partial quantity via the first partial air return line returned to the cooling chamber and fed to a conditioning device with a variably adjustable second portion.
  • the conditioning device the steam-air mixture is conditioned or prepared for reuse within the strand guide device, in particular in its cooling chamber, that is, above all, further cleaned of pollutants.
  • the processing takes place in particular by cooling, dehumidifying and/or cleaning the incoming preconditioned steam-air mixture.
  • the processing advantageously goes to such an extent that the conditioned steam-air mixture at the outlet of the conditioning device satisfies even the latest strict limit values for air pollution control.
  • the steam-air mixture conditioned in this way is intended and suitable, largely or completely, for the strand guide device, in particular their cooling chamber to be supplied again as additional air (3rd variant), so that an almost closed air circuit is created, or to be released into the hall surrounding the strand guide device.
  • the operation of the strand guide device can thus advantageously be realized at least without any environmentally harmful emissions via the chimney into the ambient air.
  • the partial air quantities are adjusted using distribution devices, e.g. distribution flaps.
  • the proportions of the individual partial air quantities can be between 0% and 100%, with the sum of the individual partial air quantities set per distribution device being 100%.
  • Figure 1 essentially shows a cross section through a cooling chamber 1 of a strand guide device 10 of a continuous casting plant, as introduced above with reference to Figures 5 and 6 was described as prior art.
  • a segment 12 of the strand guide device 10 with strand guide rollers 2 is shown in cross section, between which the casting strand 13 is guided.
