Definitions

  • the invention relates to an apparatus and a method for cooling a material web, in particular a printed and heated in a hot air dryer paper web in a web-fed rotary printing press, according to the preamble of claim 1 and claim 11.
  • a dryer for example a hot air dryer, in which the web by hot air from For example, about 300 ° C is dried while passing through the dryer.
  • the web After leaving the dryer, the web has a temperature of, for example, about 100 ° C and, before it is fed to a downstream folder, passed through a cooling device, for example a chill roll stand, in which they are guided by cooling rolls through which cooling fluid flows is cooled to, for example, about 20 ° C.
  • the necessary increase in temperature for example, by burning a fuel gas in a combustion chamber and / or the afterburning of the evaporated solvent from the web causes a portion of the heated and post-combusted air is energetically unused as waste heat fed to a fireplace.
  • a cooling capacity of the order of, for example, 100 kW is required for the operation of the cooling device.
  • a device for drying and cooling of freshly printed paper webs in which the required heat energy for the operation of a Absorption refrigeration system is supplied by the hot exhaust gas to a secondary combustion chamber.
  • the hot exhaust gas is first supplied to a heat exchanger, in which a part of the heat is transferred to a heating medium in a first circuit, wherein the hot medium flows through a heating coil in a digester.
  • gaseous refrigerant is expelled from a refrigerant solution, for example an ammonia solution, at elevated temperature and pressure, which is supplied in a second circuit to a condenser in which a third loop cooling coil connected to a recooler is arranged.
  • the gaseous refrigerant is liquefied by heat exchange with the circulated cooling water of the third circuit and fed in the second circuit via an expansion valve to an evaporator in which in turn a heating coil is arranged, which is connected to the cooling registers of a cooling device via a fourth circuit. Heat is transferred to the refrigerant via the heating coil in the evaporator and thus a heat transfer medium in the fourth circuit cools.
  • the low pressure refrigerant vapor passes via the second circuit to an absorber where it is absorbed in low concentration refrigerant solution.
  • a cooling coil of a fifth circuit is arranged, which dissipates the released in the absorber heat of absorption.
  • the now enriched refrigerant solution is pumped back into the digester within the second circuit by a pump at elevated pressure, while at the same time from the digester via a control valve low-refrigerant solution is supplied to the absorber.
  • This device has the disadvantage that it has a very complex structure, in particular comprises five separate heating and coolant circuits and thereby on the one hand generates high investment and operating costs and on the other has very large dimensions, so provided at cost a correspondingly large footprint must become. Furthermore, it is disadvantageous that the device for operation requires a highly volatile refrigerant, which leak in leaks of the usually closed second circuit in the pressure chamber and can lead to environmental and health damage.
  • prior art steam jet vacuum pumps are known, for example those sold by Schutte & Koerting which create a vacuum by means of high pressure steam.
  • the high-pressure steam is first supplied to a nozzle, from which it flows while reducing the pressure and simultaneously increasing the speed of the steam in a downstream of the nozzle tapered portion of the steam jet vacuum nozzle.
  • a vacuum is created at a lateral opening which communicates with the central portion.
  • the steam flows through a widening section of the steam jet vacuum nozzle, wherein the speed decreases again and the pressure of the steam increases again, so that it can escape against an external pressure from the steam jet vacuum nozzle.
  • the invention is accordingly an object of the invention to provide a device which causes the cooling of a web by a simple structure, and thereby at a cost savings while maintaining high reliability. Furthermore, it is an object of the present invention to provide a device for cooling a material web, which comprises only very few moving parts and works without chemicals, which make special demands on the construction and the operation of the device.

  • the apparatus may both have a first steam jet vacuum nozzle which generates a first negative pressure applied to the cooling medium and at least one second steam jet vacuum nozzle which generates a second negative pressure which is greater than the first negative pressure is and with which the cooling medium is applied.
  • the first steam jet vacuum nozzle can generate a pre-vacuum, from which starting at least one further Steam jet vacuum nozzle either generates the desired vacuum or again generates only an intermediate vacuum, which can be gradually reduced by further steam jet vacuum nozzles.
  • This also makes it possible, for example, advantageously, instead of an extremely powerful steam jet vacuum nozzle, to operate a plurality of lower-powered steam jet vacuum nozzles for generating a desired vacuum. Since the steam jet vacuum nozzles, as already mentioned, advantageously have small dimensions, there is also the advantage that even when using a plurality of steam jet vacuum nozzles in the apparatus for cooling a material web, there is only a relatively small overall space requirement.
  • the sub-chamber has at least two sections or at least two sub-chambers, which are connected to each other for exchanging cooling medium, wherein the sections or the sub-chambers are subjected to different sized sub-pressures.
