Definitions

  • the present invention relates to improvements made to electric generators of infrared rays.
  • Apparatuses of the kind in question are produced either in the form of a bare filament under vacuum or not, or coated with refractory material, or in the form of a surface deposit of a electro-resistant material on an electrical insulator so that it is capable of reaching a temperature between 1000 and 2500 ° C by circulation of an electric current.
  • This generator emits infrared rays of short wavelength, that is to say of which the majority of the emission is between 0.75 and 3 microns.
  • Such electric generators are used either as electric heating, or even as industrial heating, for example to treat the coating of a support such as a paint for its baking.
  • the improvements which are the subject of the present invention aim to allow the production of an electric generator of infrared ray comprising a broad spectrum.
  • a heat-refractory support having transparency to the infrared rays emitted by the emitter, said support being brought to a temperature at which it emits infrared rays of wavelengths greater than those of the spokes of the transmitter itself.
  • the refractory support may be covered in its bulk or on the surface with an oxidation catalyst, so that if the heating of the bodies placed under the action of the generator according to the invention produces an evaporation of solvent or other flammable gas , they are oxidized at the level of the catalytic support before they heat up to the auto-ignition temperature.
  • An electric generator is therefore obtained which can operate in an explosive atmosphere and which, by oxidation of the combustible gases in contact with the catalyst, makes it possible to purify the atmosphere in question.
  • this purification operation also corresponds to the oxidation of any combustible gas found in the heated atmosphere.
  • the electric generator of infrared rays illustrated in fig. 1 essentially comprises a conventional device 1 - formed of a housing 2 in which are located two emitters of infrared rays which have been referenced 3 and 4. These emitters can be produced either by means of a tungsten filament placed in an envelope of quartz in the open air or under vacuum, either using electric lamps, or in the form of an armored electrical resistance, that is to say composed of a filament coated with magnesia in a metal casing, or an electro-resistant deposit covering an electrical insulator.
  • the emitters 3 and 4 are constituted by what is known in the art as a quartz tube capable of reaching a temperature of approximately 2,500 ° C. when it is traversed by an electric current.
  • the two transmitters are each placed in front of a reflector 5 respectively 6, of suitable shape and made of a material having the qualities necessary for reflecting the infrared rays. There is no need to describe in more detail such a device that is commercially available, whether it is single or multiple transmitters.
  • the casing 2 is protected by means of a heat refractory support assigned to the general reference 7.
  • This support is established in the form of a screen 8 of refractory material such as for example silica, alumina, zirconia, said screen being in the form of a rectangle whose dimensions correspond to that of the opening of the housing 2.
  • This screen is limited by two grids 9 which are associated with wings 10, 11 which overlap the housing 2 in the manner of a cover, as illustrated in FIG. 2.
  • the material chosen to make the screen 8 has transparency to the infrared rays emitted by the emitters-3 and 4.
  • said transmitters generate infrared rays short wavelength, that is to say between 0.75 and 3 microns (majority of the emission) which cross the screen 8 while heating it so as to very significantly increase its temperature.
  • the screen 8 is brought to a temperature of between 400 and 1000 ° C., so that it emits clean infrared radiation whose wavelengths are greater than those of the emitters 3 and 4.
  • the former penetrate the matter in question, while the latter are confined to surface action .
  • the emission of a broad spectrum allows an action in all the thickness of the matter.
  • the screen 8 is impregnated on the surface or in the mass with at least one catalyst such as platinum, paladium, nickel, iron, etc. or mixtures of these metals.
  • at least one catalyst such as platinum, paladium, nickel, iron, etc. or mixtures of these metals.
  • the device is slightly modified and in particular the housing 2 is associated with a conduit 12 terminating in the space 13 located at the rear of the reflectors 5 and 6. These include longitudinal outlets 5a, 6a putting in communication the space 13 and the compartments determined between each deflector and the screen 8.
  • the purifier can operate by natural convection, that is to say by simple contact of combustible gases with the catalytic screen or by forced convection as has been shown, that is to say by suction in line 12 so that the combustible gases and vapors contained in the heated atmosphere pass through the catalytic support in the direction of the dashed arrows.
  • suction in line 12 so that the combustible gases and vapors contained in the heated atmosphere pass through the catalytic support in the direction of the dashed arrows.
  • We can also reverse the flow with the same objective, but by obtaining improved cooling (of the) or sources of infrared rays.
  • the gases or vapors are sucked with the air contained in the heated atmosphere and sent under pressure to the device in order to cross the screen from the inside to the outside in the direction of the arrows in solid lines in fig . 4.
