Definitions

  • the present invention relates to a device blowing and suction unit incorporating a energy exchange between the two flows.
  • Hot air dryers blow on the surface of the moving tape to achieve both energy and mass transfers. Charged supply air moisture is then removed by a suction means.
  • Infrared dryers deliver energy by radiation. Mass transfer is carried out by a blowing parallel to the surface of the strip in scroll. The blown air charged with humidity is then evacuated by means of suction.
  • the purpose of the present invention is to provide a combined blowing and suction device which reduces the volume of flows in circulation while when working at high blowing temperatures.
  • the invention is based in particular on the convective-radiative device described in the request for European patent n ° 98 402 768.0.
  • This device puts precisely the supply air flows and suction such as air flow temperature suctioned is greater than that of the blown flows.
  • the original contiguous arrangement of the blowing means and suction offers the possibility of achieving a useful energy transfer between blowing flows and suction.
  • the drying device is characterized in that it includes means for perform an energy exchange between the flows of blowing and suction, either by heat exchange, either by mass exchange.
  • the air dryers shown in the attached figures are, for example, part of the installation for drying a strip of paper such as described in the European patent application No. 98 402 768.0 in the name of the Claimant.
  • This installation includes a succession of air dryers and radiant burners gas.
  • Each drying device involves flows supply and suction air. Due in particular to the presence of radiant burners between the devices air drying the suction flow temperature is higher than the temperature of the blowing flow.
  • each device for drying includes means for performing an exchange energy between the blowing and suction flows.
  • the above means are suitable for perform a heat exchange between the flows of blowing and suction.
  • the drying device includes a compartment for air supply 1 having an inlet 2 and an outlet 3 supply air.
  • This blowing compartment 1 is adjacent to two air intake compartments 4 each comprising (see Figure 2) an entry air intake 5 adjacent to the air outlet 3 of blowing the blowing compartment 1.
  • the air blowing compartment 1 is separated from each suction compartment 4 by a wall 6 having a crenellated or corrugated profile for promote heat exchange between the air flow passing through the blowing compartment 1 and the flow air passing through the suction compartments 4.
  • the compartment of blowing consists of a series of tubes 10, 10a, 10b whose wall 11 has to promote the heat exchange of the fins 12 projecting at inside the suction compartments 4.
  • the two suction compartments 4 are arranged symmetrically on either side of the compartment blowing.
  • the tubes supply air 10a extend along a plane inclined by compared to the vertical side walls 13 of the two suction compartments 4.
  • This arrangement increases the surface tubes 10a which promotes heat exchange.
  • blowing tubes 10a, 10b have upstream of their blowing air outlet 3, a duct 14, 15 shaped to suck in air through venturi effect to mix this air with the one that is blown at the outlet of the blowing tubes 10a, 10b.
  • the mixture between the suction and blowing could also be done by a means suitable mechanical.
  • the temperature of the suction stream is higher than the temperature of the blowing flow.
  • the energy exchanges between flows suction and blowing effect reheat the air which is blown on the paper strip 16, which increases the drying efficiency.
