Definitions

  • the present invention relates to an installation for drying a moving web material, in particular paper.
  • the document US 6,088,930 discloses a convection and radiation system for the heat treatment of a strip which moves opposite gas infrared radiant elements and elements blowing hot air onto this strip.
  • the system comprises a succession of blowing elements separated from each other by at least one gas infrared radiant element.
  • Each blowing element comprises on each side a suction element extending close to a gas infrared radiant element.
  • the document WO 2005/085729 describes a system resulting in reduced consumption of mechanical energy and reduced loss of thermal energy, reduced investment and operating costs, and requiring less space.
  • This drying installation is characterized by the fact that the suction, and possibly blowing, devices of the system mass transfer devices comprise at least one suction device, and possibly a blowing device, installed opposite the bandwidth with respect to corresponding suction and blowing ducts which extend at least in the transverse direction of the bandwidth, and arranged to suck and/or blow said combustion products so as to optimize the vector averages.
  • the vectors represent the respective trajectories of the different jets of combustion products sucked and/or blown.
  • the present invention aims to improve the operation of the installations described above.
  • the present invention aims to provide an installation for drying a moving strip material, which is more environmentally friendly.
  • the present invention aims to provide an installation for drying a moving strip material, having a lower ecological impact.
  • the installation also comprises a device for treating the combustion products, the treatment device comprising an oxidation and/or reduction catalyst, and being mounted on or downstream of said extraction pipe in order to treat respectively the carbon monoxide and/or the nitrogen oxides contained in the combustion products.
  • the treatment device comprising an oxidation and/or reduction catalyst, and being mounted on or downstream of said extraction pipe in order to treat respectively the carbon monoxide and/or the nitrogen oxides contained in the combustion products.
  • the catalyst may comprise, for example, a catalyst for the oxidation of carbon monoxide to carbon dioxide and/or a catalyst for the reduction of nitrogen oxides NOx to nitrogen N2.
  • the treatment device allows the gases released by the installation to be treated, in order to limit the quantity of carbon monoxide and/or nitrogen oxides present there.
  • the installation includes in particular a regulation means configured to regulate the temperature of the catalyst to a temperature greater than or equal to 130°C, preferably greater than or equal to 150°C, and more preferably greater than or equal to 200°C, or even 300°C or 400°C.
  • the installation is configured to operate the treatment device at its optimal temperature conditions. More specifically, the installation is configured to operate the treatment device at a temperature that allows for high efficiency throughout the operation of the installation.
  • the regulating means is configured to heat the catalyst to a temperature greater than or equal to 130°C, preferably greater than or equal to 150°C, and more preferably greater than or equal to 200°C, or even 300°C or 400°C, and/or the regulating means is configured to maintain the catalyst at a temperature greater than or equal to 130°C, preferably greater than or equal to 150°C, and more preferably greater than or equal to 200°C, or even 300°C or 400°C.
  • the installation is configured to operate the catalyst under its optimal temperature conditions, so as to obtain a high efficiency of the oxidation and/or reduction reaction, throughout the operation of the installation.
  • Heating the catalyst to very high temperatures, in particular 300°C or 400°C, can also make it possible to obtain, at the outlet of the treatment device, the same efficiency but with fewer precious metals in the catalyst than for a treatment device operating at a lower temperature.
  • the regulating means comprises a heating element, such as an electrical element and/or a heat exchanger and/or an inductive means, configured to supply heat to the catalyst.
  • a heating element such as an electrical element and/or a heat exchanger and/or an inductive means, configured to supply heat to the catalyst.
  • the electrical or inductive heating means for example a heating resistor or a coil, makes it possible to obtain a rapid and controlled increase in the temperature of the catalyst.
  • Such an electrical or inductive heating means is particularly suitable during periods of transient operation of the installation, for example at start-up, during which the combustion products to be treated may have a temperature lower than that desired for the operation of the treatment device.
  • the inductive heating means is particularly advantageous for concentrating, by choice of material and/or geometry, the transfer of energy to locations on the catalyst where the thermal energy will be most useful.
  • the heat exchanger can be used to reuse calories available elsewhere, in particular in the installation, to increase the temperature of the catalyst, while limiting the energy consumption, in particular electricity, of the installation.
  • the regulation means comprises control means configured to control the radiating or heating elements, and/or the gas flow circulation system and/or the treatment device, in order to regulate the temperature of the catalyst.
  • the control means may in particular be configured to control valves, flaps, etc., in particular in the system of circulation of gas flows, or even the supply, power, distribution, etc., of radiating or heating elements.
  • the regulating means comprises at least one carbon monoxide and/or nitrogen oxide sensor mounted upstream or downstream of the catalyst and configured to respectively measure the quantity of carbon monoxide and/or nitrogen oxides contained in the combustion products upstream and/or downstream of the catalyst.
  • the regulating means may comprise a carbon monoxide sensor, and possibly nitrogen oxides, mounted upstream of the catalyst, and a carbon monoxide sensor, and possibly nitrogen oxides, mounted downstream of the catalyst.
  • Carbon monoxide and nitrogen oxide sensors are used to determine the quantities of carbon monoxide and nitrogen oxides present in the combustion products to be treated and feeding the treatment device. Such sensors also make it possible to determine the effectiveness of the treatment device in oxidizing carbon monoxide or reducing nitrogen oxides. For example, such sensors can identify normal or abnormal wear of the treatment device, or an anomaly or even a drift in the operation of the treatment device.
  • the regulation means is configured to trigger an alert when the quantity of carbon monoxide and/or nitrogen oxides contained in the combustion products downstream of the catalyst is greater than a defined threshold.
  • the regulation means is configured to maintain the catalyst at a temperature greater than or equal to 130°C, preferably greater than or equal to 150°C, and more preferably greater than or equal to 200°C, or even 300°C or 400°C, when the quantity of carbon monoxide and/or nitrogen oxides contained in the combustion products upstream of the catalyst is greater than a defined threshold.
  • the installation includes means for adding fresh air, for example into the gas or gas mixture supplying the radiant or heating elements and/or into the combustion products.
  • the installation also comprises means for adding fresh air, configured in particular to modify the quantity of fresh air present in the combustion products, and control means configured to control said means for adding fresh air.
  • the addition of fresh air may be carried out upstream of the combustion, for example in the gas or gas mixture supplying the radiant or heating elements, or downstream of the combustion, for example in the combustion products formed by the radiant or heating elements.
  • the means for adding fresh air may be a controlled valve modifying the composition of the gas, or gas mixture, supplying the radiant or heating elements, or may comprise a valve mounted on the extraction pipe and/or a cooling air inlet in the installation.
  • the installation according to the present invention comprises means for adding fresh air to the gas, or gas mixture, supplying the radiating or heating elements, and control means controlling the quantity of fresh air added to the gas supplying the radiating or heating elements as a function of the temperature or the composition of the combustion products entering the oxidation and possibly reduction catalyst.
  • the amount of air in the gases supplying the radiant or heating elements is generally greater than that required by the stoichiometry of the combustion reaction, in order to ensure complete combustion. However, if the amount of carbon monoxide in the combustion products is low, this indicates that complete combustion is taking place: it is then possible to reduce the amount of fresh air supplying the radiant or heating elements, provided that the amount of carbon monoxide in the combustion products remains low.
  • the installation also comprises means for determining the temperature of the catalyst, for example a temperature sensor mounted upstream of the catalyst, for example in the extraction pipe.
  • the regulation means may comprise said means for determining the temperature of the catalyst.
  • the installation also comprises means for adding fresh air to the combustion products and/or to the gas supplying the radiant or heating elements, a temperature sensor mounted in the extraction pipe, upstream of the catalyst, and control means monitoring the quantity of fresh air added to the combustion products and/or to the gas supplying the radiant or heating elements.
  • the means for adding fresh air comprise a controlled valve mounted on the extraction pipe, and configured to adjust the quantity of fresh air mixed with the combustion products.
  • the valve control adjusts the amount of fresh air added to the combustion products, thereby changing their temperature. This adjusts the temperature of the combustion products just before they enter the catalyst.
  • the regulating means comprises said control means.
  • the control means may comprise manual control means.
  • the catalyst comprises a metallic or ceramic honeycomb support, with at least one portion coated with one or more precious metals and/or with a means for injecting a reducing agent, for example ammonia.
  • a reducing agent for example ammonia.
  • Such supports make it possible to obtain very high active surfaces for a defined volume, which makes it possible to obtain higher yields.
  • the installation also includes a catalyst cleaning device.
  • the unclogging device is intended to eliminate any accumulation of residues within the catalyst that may block certain channels for the gas to be treated. In order to maintain the efficiency of the catalyst, the unclogging device can be used at regular intervals or when the pressure drop across the catalyst exceeds a defined threshold, in order to restore its nominal performance.
  • the catalyst unclogging device is a device for circulating a pressurized fluid, for example compressed air, through the catalyst.
  • Compressed air can be used to unclog the catalyst.
  • the sudden injection of compressed air into the inlet gases creates a sudden overpressure at the catalyst inlet, which can break up the accumulations of residue and evacuate them with the rest of the treated gases. This results in a catalyst operating as intended.
  • FIG. 1 schematically illustrates an example of a drying installation 1 for the continuous drying of a moving web material 2 according to the invention.
  • the web material 2 moves in the direction indicated by the arrow 4 through the drying installation 1.
  • the regulation means 22 can be configured to allow a rapid modification of the temperature of the catalyst 20 when it is outside said nominal temperature range, and/or to allow the temperature of the catalyst 20 to be maintained when it is within said nominal temperature range.
  • the regulation means 22 may comprise a heating element 24, such as an electrical element and/or a heat exchanger, for example mounted in or in contact with the catalyst support 20, in order to heat the latter when its temperature is too low, in particular during the start-up phases of the installation 1.
  • the heating element 24 is thus used temporarily, in order to bring the catalyst to its nominal operating conditions until it can remain there independently.
  • the heat exchanger can be advantageously used to recover the calories released elsewhere in the installation and to supply them to the catalyst in order to heat it without increasing the energy consumption of the installation.
  • the regulating means 22 can also regulate the temperature of the combustion products feeding the catalyst 20, so that they have a temperature included in the nominal temperature range of the catalyst 20, so as to put or maintain the catalyst 20 in its nominal temperature range.
  • the use of the unclogging device 30 can in particular be controlled as a function of the operating time of the catalyst 20, for example with an unclogging procedure planned every 20, 30 or 50 hours of operation of the catalyst 20.
  • the unclogging device 30 can be controlled as a function of the evolution of the pressure drop between the inlet and the outlet of the catalyst 20, for example when such a pressure drop exceeds a defined threshold or increases, for a defined time, by a defined value.
  • the treatment device is configured to operate for as long as possible in its nominal zone, including during transient periods, in particular start-up.
  • prolonged operation is ensured thanks to the unclogging device which makes it possible to maintain the catalyst capable of treating the combustion products conveyed by the extraction pipe.
