Definitions

  • This invention relates to a method for removing gasifiable solid or liquid materials from a heat-withstanding carrier in a whirl-bed, and to the equipement used thereby.
  • the resulting gases reach the whirl-bed surface and then together with lighter materials which are carried along with the gases, have to be treated, possibly purified in a separating device, to prevent or at least minimize polluting the environment.
  • the invention also relates to an equipment particularly intended for the working of said method and actually in such conditions which allow a faster and more thorough cleaning of what has been called hereinbefore a heat-withstanding carrier. Actually it is in most cases a matter of metal parts which are completely coated with paint or plastic material, or which bear traces thereof. The most varied "carriers" may then also be treated in such a whirl-bed.
  • the equipment for the working of this method which makes use of a vat wherein the carriers to be treated are located in a heated whirl-bed comprised of granulate grains, has for characteristic that said granulate grains are divided into at least two layers, namely a lowermost layer inert granulate grains wherein a gas-air mixture will be blown, and above said latter layer, there is provided a layer granulate grains which form with the igniting of the gas-air mixture, the whirl-bed proper.
  • perforated pipes are present in said inert granulate grains, to let the gas-air mixture therein.
  • a detail of the invention lies in a post-combustion chamber connecting to said vat, in which chamber lines for feeding propely air open, and at least in said combustion chamber, a pilot flame is provided for igniting the gas-air mixture which escapes on the whirl-bed surface.
  • the single figure is a diagrammatic showing, partly in a vertical section, of an equipment according to the invention.
  • the equipment is comprised of a vat, shown generally in 1, with two upstanding wall 2 and a bottom wall 3.
  • the vat 1 is filled with heat-withstanding granulate grains, such as for example quartz sand or aluminum oxide or similar. This forms the whirl-bed 4 proper. Possible sizes of the material the whirl-bed proper is comprised of, lie for example between 200 and 300 microns.
  • a layer inert granulates 5 wherein at least one, but preferably a plurality of pipes 6 are present for blowing the gas-air mixture into the whirl-bed 4.
  • the layer inert granulates 5 is a layer which is mainly comprised for example of gravel, baked- clay mouldings or other fire-proof materials the sizes of which are larger than the sizes of that material which comprises the whirl-bed proper.
  • the layer inert granulates completely surrounds the pipes 6, and due to the specific weight and larger diameter of that material the inert layer is made of, said layer is never brought into motion, so that wear of said pipes is not to be expected.
  • the ideal area for flame-forming lies in that area exactly above the dashed line between the whirl-bed proper 4 and the layer inert granulates 5, while the very hot gases insure forming of the above-lying fluidized whirl-bed.
  • the inert granulate layer 5 forms a cold boundary layer relative to the whirl-bed 4.
  • said boundary layer has all the advantages of the conventional and known flashback apparatus. This results in the flame being fixed inside the whirl-bed a short distance above the inert granulate layer 5.
  • the main flame Due to the low speed of the gas-air mixture through the whirl-bed, the main flame is fixed over the whole whirl-bed surface area. Consequently the gas mixture can bring the whirl-bed faster to the required temperature (generally 650°C). This is due to the outstanding heat-transfer in the whirl-bed proper and the contact between the flame and the fluidized grains in said whirl-bed.
  • the whirl-bed temperature is adjustable by means of an automatic temperature regulator which adjusts accordingly the gas flow-rate.
  • the pyrolysis gases generated by the combustion of the paint or plastic remains present on the surface of those metal parts which have been dipped in the whirl-bed, are ignited.
  • a large number heat-withstanding carriers for example metal parts
  • the workpieces to be treated are brought from the top into the whirl-bed, with or without making use of a supporting frame ⁇ r basket. Due to the very rational whirl-bed temperature, the workpieces treated therein are not distorted and there is obtained an accurate temperature control over the whole whirl-bed volume.
  • the gasification of the material to be removed on the workpiece occurs inside the whirl-bed.
  • the pyrolysis gases rise through the whirl-bed to the surface thereof.
  • the pyrolysis gases mix in the whirl-bed with the gas-air mixture, in such a way that a homogeneous mixture of gas, air and pyrolysis gases is ignited on the whirl-bed surface.
  • a pilot flame 13 is present above said whirl-bed and during the whole operation time. Said pilot flame burns continuously, independently of the presence of pyrolysis gases.
