Definitions

  • the invention relates to blasting methods for cleaning pipes according to The preamble of claims 1 and 3 and a device according to the preamble of claim 6, which are suitable for performing this method.
  • Blasting devices are generally used to clean surfaces with the help a mostly gaseous blasting medium, to which an abrasive blasting medium such as Sand or the like can be added. It is also known as an abrasive To use dry ice or dry snow (DE-A-195 35 557).
  • the stake of dry ice has the advantage that the ones to be cleaned and then materials to be disposed of are not increased by additional blasting media, because Dry ice evaporates after use.
  • a blasting method is known from US-A-5 664 992, which describes the closest prior art, in which the blasting nozzle first tapers and then widens again, so that acceleration of the blasting medium is reached.
  • a spindle-shaped deflector becomes common with the jet nozzle through the tube moves and directs the abrasive Abrasive on the pipe wall.
  • the object of the invention is to provide blasting methods and a blasting device create an efficient and thorough cleaning of the inner surfaces of pipes or other hollow bodies, especially with dry ice.
  • the deflector alone, ie without the nozzle moved through the pipe, the movement of the deflector must be braked, thus its speed is always lower than the flow speed of the blasting medium and the desired deflection effect is achieved.
  • This braking is done with the help of a pull rope or from the opposite Pipe end here, with the help of a rod.
  • the flow of the blasting medium can be at one end of the to be cleaned pipe arranged pressure or suction blower generated.
  • the centering of the deflection cone on the pipe axis can either be purely aerodynamic can be achieved or with the help of at least three flexible guide rods or runners that guide the deflecting cone as it moves form through the pipe.
  • the deflection cone can also be used with regard to the ability to pass through bends be flexible yourself.
  • a e.g. spherical deflector instead of the deflection cone may be provided.
  • As an abrasive dry ice is used. It is advantageous that the suspension of the deflector is not in the middle, but on the circumference of the nozzle the shock-sensitive pellets are not broken up prematurely.
  • the pressure and volume output of the pressure source is preferably based on the Blasting nozzle matched that the blasting medium at the constriction of the nozzle Speed of sound reached. Because of the Laval effect, this can be done Blasting medium then in the downstream part of the nozzle to supersonic speed accelerate so that a particularly intensive cleaning effect is achieved becomes.
  • a stationary shock wave forms at the tip of the deflection cone in the shape of a Mach cone. This shock wave probably helps keep the abrasive away from the surface of the deflection cone.
  • the device when cleaning pipes, the device has a certain degree of bendability is desirable, the holding bars and a lance carrying the jet nozzle be flexible.
  • Skids or other centering devices can be used to center the jet nozzle in the pipe be provided. When the jet nozzle is pulled through the pipe aerodynamic self-centering effects can also be used for centering the jet nozzle can be used.
  • the outer diameter of the nozzle needs itself not to be larger than the outer diameter of the deflector, so that a slim, also suitable for pipes with a small inner diameter Design is achieved.
  • the nozzle can be used as a Laval nozzle be formed with which high flow velocities of the blasting medium, if necessary, even allow supersonic flows to be achieved.
  • the additional blasting agent can be a slightly abrasive blasting agent.
  • a highly abrasive blasting agent such as blasting granulate can be added.
  • chemical agents such as descaling agents.
  • a cold gas for example cooled N 2 or the like, to the blasting medium.
  • the additional blasting media should be designed / dosed so that they have no or only bring as little waste growth as possible and no damage - e.g. due to subsequent corrosion - on the surfaces to be cleaned.
  • the additional blasting media can be added by mixing with dry ice.
  • the mixing ratio can be selected as required.
  • the additional blasting medium can also be caused by the dynamic pressure of the blasting medium (additionally) be sucked in (injection nozzle). This suction can through a branching line in the nozzle or in the line feed between dry ice input device and the jet nozzle.
  • the pressure of the blasting medium, with the help of which the additional blasting medium is fed should be similar to the pressure of the main stream or so high that a back pressure of the additional blasting agent caused by back pressure is avoided and a uniform jet of the merged blasting media and blasting media is achieved.
  • the blasting device shown in FIG. 1 has, in a manner known per se Pressure source 10, for example an air compressor, which over a flexible pressure hose 12 is connected to a jet nozzle 14.

  • the blasting medium carried in the gas jet is also radially outwards due to aerodynamic effects deflected and thus exerts its abrasive effect on the wall of the pipe 20. while only a negligible part of the carried particles comes into contact with the deflection cone 30.
  • the deflection cone 30 is with the help of three rods 36 arranged at angular intervals of 120 ° on the jet nozzle 14 held. This ensures that the tip of the deflection cone 30 is always precisely centered on the axis of the jet nozzle 14.

  • the rods 36 are designed here as round rods, which have thinner end sections 38 in corresponding axial bores 40 of the deflection cone 30 and the jet nozzle 14 engage.
  • the end portions 38 and the bores 40 can be provided with right and left hand threads so that the rods screw with the jet nozzle and the deflection cone.
  • the holes 40 of the deflection cone 30 are at the end facing the jet nozzle 14 gradually expanded and take the thicker central section of the round bars 36 on, so that a clean connection of the round rods to the deflection surface of the cone is reached.
  • the thicker middle sections of the round bars 36 meet butt against the end face of the jet nozzle 14, so that a defined distance is maintained between the jet nozzle and the deflection cone 30.
  • the arrangement can also be such that the round bars also engage in enlarged bores in the jet nozzle 14. In this The case can be the axial distance between the deflection cone 30 and Jet nozzle 14 vary continuously within certain limits, so that the Beam characteristics can be optimized.
