Definitions

  • Explosion cleaners are carried out.
  • a textile bag is outside the space to be cleaned filled with a gas mixture and introduced into the room to be cleaned, and there brought to the explosion.
  • the entire explosive effect from the textile bag which can be ideally assumed as a ball emanates.
  • the problem here is that, although contaminants that are applied to the outside of the pipes or room interior walls and that can be achieved directly from the blasting effect, may possibly be eliminated.
  • the lines that receive the medium to be heated are often very close to each other, the blasting action can only remove a small portion of the contaminants, but often impurities that are behind the tubes between the tubes or from the blast.
  • a spherical detonation is not carried out within the combustion chamber, but a linear detonation, i. H. So a blast, in which the explosive effect is distributed over a large length.
  • a pipe, z. As a tube made of cardboard and / or copper, filled with a gas mixture and / or inside with a detonating cord, so that the desired explosive effect can be achieved by the blasting. Due to the explosion according to the invention, a shock wave is generated, which breaks off when it hits dirt to be cleaned off.
  • EP 1 226 881 discloses a method for cleaning surfaces, for example, pipes and pipe walls of steam generators or heat exchangers in process engineering, metalworking and the like thermal treatment and recovery of waste.
  • an explosive acetylene and oxygen-containing gas mixture is used.
  • the acetylene and oxygen-containing gas mixture is placed in a closed container and ignited.
  • the device has a steel tube in which a polyethylene gas bubble is arranged, which is slipped over an igniter and Gasein sleepllINA and sealed gas-tight.
  • EP 1 067 349 A2 discloses an apparatus and method for purifying slag in heat units.
  • the device proposed therein comprises an explosive device which is arranged at one end of a stem, wherein the stem serves to bring the explosive charge in the vicinity of a surface to be cleaned. To avoid premature ignition of the explosive charge in the unit, the device is equipped with a cooling device.
  • EP 0 109 351 A1 discloses a burnout element for chimney stacks, chimneys and the like having an elongate sleeve on which is applied a multi-layered roll of flammable fabric having a coating of a waxy material on each coil layer.
  • US 2,839,435 discloses a method for removing deposits in a reactor chamber by explosive means. For this purpose, several holes are drilled in the deposits, are used in the explosive charges, which are connected with fuses and connected by means of a detonation device, which is located outside the reactor chamber.
  • EP 1 275 925 A1 discloses a method and apparatus for the removal of slag by blasting, wherein a blasting means at the front end of a long lance in the immediate vicinity of the destroying Material is led.
  • a coolant is introduced into the cooling head designed as a double tube with cooling head and supply head via the lance in the supply head, so that it flows past the explosives containing explosives container.
  • WO 98/16329 discloses a cleaning, inspection and repair system for a steam generator of a nuclear power plant.
  • the system uses water jets for cleaning.
  • the system has an extendable telescopic arm or flexible arm with multiple cleaning nozzles attached.
  • the tube can be made arbitrarily long depending on the application and, as seen in the example shown, the tube has a relatively small diameter of for example 3 cm to 15 cm, so that it can also be introduced into the lanes of the heat exchanger lines within the combustion chamber ,
  • the parts such as filling head extinguishing spark plug, threaded rod, shutter etc. can be reused.
  • FIG. 3 shows an alternative embodiment. It can be seen that in the combustion chamber, a first tube is inserted, which is connected via a joint with a second tube. Through the joint, the respective angle of the second tube (detonator) can be set as desired.
  • FIG. 4 shows in the example a view for an exemplary embodiment of the invention.
  • a first tube 1 is connected to a second tube 2 via a hinge.
  • an igniter is arranged, which is connected to a detonating cord.
  • a detonating cord (and possibly an explosive gas mixture) trained and the detonating cord is connected to the detonator.
  • the first tube as well as the second tube is flowed through by a cooling medium, in the example shown, an air / water mixture.
  • the igniter is connected via a firing line to the trigger of the ignition mechanism outside the tube.
  • the cooling medium flows into the first tube and over the joint also into the second tube, so that the detonator and the detonating cord are sufficiently cooled, so that an unforeseen explosion is not triggered prematurely.
  • the outer tube 2, z. B. if this is made of cardboard, glass, metal, copper or plastic, splintered (destroyed) (as in a hand grenade) and the individual particles blown off encounter the contamination of the pipes to be cleaned within the combustion chamber. The impurities are removed here.
  • the cooling amount can be adjusted so that an unforeseen detonation is not prematurely caused.
  • the blasting pipes are dimensioned so that they also fit between the lines to be cleaned within the combustion chamber and thus contaminants can be removed from the lines, which are seen from the combustion chamber between the lines or behind them ,
