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 electrically 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 cooking.
  • an infrared ray heater comprising a box containing at least one tube emitting such rays, said box being closed towards the front by a piece of silica cloth . This screen promotes the diffusion of heat and provides protection for the electric transmitter.
  • the silica screen constitutes a re-emitter of infrared rays at wavelengths different from those of the emitters, and that this screen is permeable to the infra-red rays emitted by the latter.
  • the improvements which are the subject of the present invention aim to produce an atmospheric purifier operating at the same time as it emits infrared rays with a broad spectrum.
  • a heat-refractory support having a transparency to the infrared rays emitted by the transmitter, said support being brought to a temperature at which it emits infrared rays of longer wavelengths than those of the rays of the emitter itself.
  • the refractory support constitutes a catalytic screen making it possible to oxidize the vapors of combustible gases coming into contact with it.
  • 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 their heating 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 generator 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 disposed in a quartz envelope 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 metallic envelope, or an electroresistant 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 housing 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 with the way 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 of 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 rise in temperature of the screen 8 due to short infrared from the emitters 3 and 4 makes it possible to operate the screen 8 in true catalytic support in contact with the combustible gases and vapors contained in the atmosphere. heated. Under these conditions, these are oxidized by said support and an atmosphere purifier is thus obtained.
  • the housing 2 of the device according to the invention is associated with a conduit 12 terminating in the space 13 located behind the reflectors 5 and 6. These comprise longitudinal vents 5a, 6a connecting 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 catality support in the direction of the dotted arrows.
  • suction in line 12 so that the combustible gases and vapors contained in the heated atmosphere pass through the catality support in the direction of the dotted 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 atmosphere, heated 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. 2.
