Definitions

  • the invention relates to a device for generating a jet of dry ice particles, with a jet nozzle, a jet line for supplying a carrier gas to the jet nozzle and a supply line for liquid carbon dioxide, which opens into the jet line via a flash chamber and at the outlet of the expansion space in the beam line a cross-sectional constriction is provided.
  • the device is part of a blasting system that serves to rid large surfaces, such as the inner surfaces of pipes or boilers in industrial plants from stuck encrustations.
  • the liquid carbon dioxide is introduced from a supply line, which is formed for example by a capillary, in a relaxation space with a larger cross section, so that evaporated by the relaxation of a portion of the carbon dioxide, while another part of the carbon dioxide condenses due to the evaporative cooling to dry ice particles.
  • the relaxation space opens, preferably laterally, in a beam line, which is traversed by the carrier gas, for example compressed air or nitrogen.
  • a nozzle preferably a Laval nozzle is provided, so that the jet to high speeds, preferably at supersonic speed, is accelerated.
  • the relaxation space is formed by a pipe socket having an internal thread. This internal thread is to form disturbing edges, where the impact of the dry ice particles should form a crust of dry ice.
  • the object of the invention is to further improve this known method and the device in order to achieve an even more efficient production of dry ice particles with a high cleaning effect.
  • cross-sectional constriction is formed by a centrally and coaxially disposed in the outlet of the expansion space displacement body.
  • the relaxation room should have a certain minimum length. Due to the cross-sectional constriction according to the invention, this minimum length can be without loss of power reduce, so that a more compact and handy construction of the device is made possible.
  • the cross-sectional constriction should be at least 20% of the cross-sectional area of the expansion space.
  • the cross-sectional constriction is achieved by approximately streamlined structures, which are well flowed around by the dry ice particles and do not form a substantial impact surface for the dry ice particles.
  • a displacement body in the form of a cone, a sphere, a hemisphere or the like is provided on the center axis of the expansion space, the pointed or rounded side of which is directed upstream.
  • the outlet cross section of the expansion space is then formed by an annular gap between the wall of the expansion space and the displacement body.
  • axial bores can be provided in the displacement body.
  • the supply line for the liquid carbon dioxide and the expansion space are arranged coaxially in the interior of the jet line, so that the narrowed outlet of the expansion space is located centrally in the steel line.
  • the displacement body can protrude into this chamber or in the beam line.
  • the device shown has a jet nozzle 10, z.
  • a jet nozzle 10 As a convergent / divergent nozzle or Laval nozzle with which a beam of a carrier gas is to be generated, which has approximately sonic velocity or supersonic speed and the solid dry ice particles are added as a blasting agent.
  • the jet nozzle 10 is connected to a jet line 12, which in turn is connected to a pressure source, not shown, and is traversed by the carrier gas, for example compressed air with a pressure in the order of IMPa and a flow rate of for example 1 to 10 m 3 / min.
  • the carrier gas for example compressed air with a pressure in the order of IMPa and a flow rate of for example 1 to 10 m 3 / min.
  • liquid carbon dioxide is supplied from a high-pressure tank or cold tank, not shown.
  • the supply line 14 is formed for example as a capillary or throttled by an adjustable aperture, so that the throughput of liquid carbon dioxide, for example, in the order of 0.1 to 0.4 kg per cubic meter of carrier gas is (volume below atmospheric pressure).
  • the supply line 14 opens into a relaxation space 16 which is widened in cross-section and which is formed by the interior of a nozzle 18 which opens obliquely into the jet line 12.
  • a relaxation space 16 which is widened in cross-section and which is formed by the interior of a nozzle 18 which opens obliquely into the jet line 12.
  • part of the carbon dioxide is vaporized, and the resulting evaporative cooling condenses another part of the carbon dioxide to dry snow, that is to solid dry ice particles.
  • These dry ice particles are transported by the simultaneously formed gaseous carbon dioxide into the jet line 12 or sucked out of the expansion space 16 by the dynamic pressure of the carrier gas and are thus distributed in the carrier gas flow and finally discharged through the jet nozzle 10 at high speed onto a workpiece to be cleaned.
  • the throughput of liquid carbon dioxide and the carrier gas throughput can be regulated.
  • a conical displacement body 20 is arranged on the central axis of the nozzle 18, which is oriented coaxially to the nozzle 18 and its tip on the mouth of the supply line 14 in the Relaxation room 16 has.
  • the effluent from the expansion chamber 16 mixture of gaseous and solid carbon dioxide, possibly with certain amounts of liquid carbon dioxide is thus displaced by the displacer 20 and thus occurs only throttled in the beam line 12, since the displacement body 20 with the walls of the nozzle 18 forms a cross-sectional constriction.
  • the residence time of the dry ice particles is prolonged in the relaxation space 16 saturated with cold, gaseous carbon dioxide, so that the dry ice particles have time to grow by condensation.
  • the cross-sectional constriction produces an uneven flow profile with the flow velocity increasing from the expansion space 16 to the annular gap between the displacement body 20 and the wall of the nozzle 18. Furthermore, the cross-sectional constriction leads to a greater density at which the Trokkeneispumble are suspended in the gaseous medium. All this promotes the growth of very solid dry ice particles, which then develop a high cleaning effect due to their size and hardness.
  • the approximately streamlined shape of the conical combustion body 20 prevents that the grown dry ice particles are crushed on impact on the displacement body 20 again.
  • FIGS. 2 and 3 the displacement body 20 is shown enlarged.
  • Axial holes 22 in the displacement body 20 make it possible to optimally adjust the flow profile of the effluent from the expansion chamber 16 medium.
  • Radial lands 24 hold the body 20 in the center of the nozzle 18 and are shaped so that they form virtually no baffles for the dry ice particles.
  • FIGS. 4 to 7 show modified embodiments of the device. These examples differ from the device FIG. 1 just by a changed form of the displacement body.
  • a displacement body 26 a hemisphere whose rounded side facing the flow direction, that is to the mouth of the supply line 14.
  • a displacement body 28 is a ball.
  • FIGS. 6 and 7 show displacement body 30, 32 in the form of an ellipsoid or a spherical cap shield.
  • the displacement body 26, 28, 30 and 32 are mounted analogously to the displacement body 20 in the nozzle 18 and may optionally also have axial bores.
  • FIG. 8 shows a modified embodiment in which an ellipsoidally expanded chamber 34 is provided between the beam line 12 and the jet nozzle 10.
  • the liquid carbon dioxide supply line 14 here runs coaxially in the jet line 12 upstream of the chamber 34 and opens into the expansion space 16, which is here at the upstream end of the chamber 34 and opens axially into this chamber.
  • the outlet of the expansion space 36 is narrowed by the conical displacement body 20 in cross section.
  • this displacement body projects somewhat into the jet line 12 or into the chamber 34 and thus effects a good distribution of the dry ice particles in the widened chamber 34.
  • FIG. 9 shows an embodiment in which the nozzle 18 at its end facing the supply line 14 has a larger cross-section, downstream of which a conically tapering section 38 connects, which here forms the extent of the expansion chamber 16 and at the same time the cross-sectional constriction of this outlet.
  • the displacement body 20 is additionally provided downstream of the conically tapered portion 38.
  • the length of the cylindrical Enspannraumes 16 should, especially in small-sized devices in which the inner diameter of the beam line 12 is smaller than about 15 mm, not too small, so that the expansion chamber has a sufficient volume.
  • the diameter of the expansion space 16 is preferably greater than the diameter of the beam line 12.
  • the cross-sectional constriction at the outlet of the expansion space is typically between 20 and 50% of the cross-sectional area inside the expansion space 16.
  • the exact extent of the cross-sectional constriction is of the respective process parameters depending in particular on the pressure and flow rate of the carrier gas, the rate of liquid carbon dioxide, the temperature of the liquid carbon dioxide and the like. In general, a cross-sectional constriction of the order of 40% is appropriate.
  • the diameter of the beam line 12 may vary, for example, between 8 and 32 mm.
