Definitions

  • the invention relates to a method and a device for the local destruction of compact materials, such as slag approaches, masonry residues, etc. in hot thermal systems such as heat exchangers, industrial furnaces, firing systems, metallurgical melting vessels, using a disintegrating agent, which at the front end of a lance in a coolant flowing through the cooling tank is arranged and brought by holding and moving the rear end of the lance through an opening of the hot thermal plant in the immediate vicinity of the material to be destroyed and ignited by an igniter at an arbitrary time.
  • hot thermal systems such as heat exchangers, industrial furnaces, firing systems, metallurgical melting vessels
  • EP 1 067 349 A2 it is proposed in EP 1 067 349 A2 to cool the explosive means arranged at the front end of a rod during the introduction into a hot, in-service heat exchanger with a coolant.
  • the disintegrating agent is surrounded by a cooling device.
  • the coolant flows in at the front end, flows through the cooling device and flows around the disintegrating means arranged at the rear end of the cooling device and then leaves the cooling device through openings in the cover which is semipermeable at its rear end.
  • the stated object is procedurally achieved by the method according to claim 1, in particular the fact that the coolant flows into the cooling head formed as a double tube with cooling head and supply head via the lance in the supply head, through the inner tube or the inner cooling jacket to the front end of the cooling head is guided and flows past the explosives containing explosives container over and then between the inner cooling jacket and the outer tube forming the cooling head housing back to the supply head and is promoted from this from the hot thermal plant out.
  • the coolant from the cooling tank and to lead out of the hot thermal system again, the disadvantages described in the introduction with known methods are avoided, namely that the coolant remains in the hot thermal systems.
  • the coolant is expediently discharged through an outside of the lance line, the length of this line the local conditions, where the coolant must be promoted adapted.
  • the supply of the coolant to the cooling tank takes place through the hollow interior of the lance, which at its front end via a screw or plug connection with the supply head of the cooling tank and at its rear end via a clutch, such as a GK clutch, with a coolant inlet, for example a pressurized water line or a coolant pump is connected.
  • a clutch such as a GK clutch
  • the explosive is cooled by the passing coolant so that even with a longer residence time of the explosive in the hot thermal plant no spontaneous ignition of the explosive can take place and a time-consuming optimal positioning of the lance with the explosive is possible.
  • the bulk pack is not arranged around the explosives container, but only at a localized location next to the explosives container.
  • aluminum powder could also be used to increase the detonation rate.
  • the disintegrant is housed in a separate container.
  • pasty, powdery or granular disintegrating agents can be used, since the disintegrant does not come into direct contact with the coolant and can not be washed away.
  • FIG. 1 shows a ready-to-use device for explosive device according to the invention with a cooling container 1 in a sectional view, consisting essentially of the cooling head 10 and supply head 11 for cooling a disintegrating means 5 with coolant 4, the cooling container 1 having a lance 3 for positioning and Supply of the cooling tank 1 is connected at the site.
  • Coolant inlet 12 is a coolant outlet 15 which connects the coolant outlet 14 of the cooling tank 1 via the flexible coolant discharge line 16 with the arranged on the lance 3 coolant drain line 31.
  • the supply head 11 has a plurality of walls 13, 17, 18. These are from the inside to the outside of the cooling head receiving tube 13, in which the explosives container 25 is inserted, the supply pipe 17 with deferred inner cooling jacket 27 and the supply housing 13 with deferred cooling head housing 23. To stabilize the Wandurgen 13, 17, 18 with each other between thedekopfamrohr 18 and the supply pipe 17 three spacer webs 26 and to offset between the supply pipe 17 and the supply housing 13 three spacer webs 24 are arranged.
  • the blasting agent container 25 inserted into the cooling head receiving tube 18 consists of a tube with closed ends 28, 29 filled with an insulating and insulating agent 53, 54, for example sand, with the disintegrating agent 5 and the primer 51.
  • the ignition cables 52 of the primer 51 are off led out the explosives container 25 and pushed through the rear wall 19 of the cooling head receiving tube 18. From there they are through the coolant inlet opening 12 and through the cavity of the lance 3 and out of this by a screw plug 33 to an example electric ignition (the ignition device is not shown) out.
  • the explosives container 25 is located between the explosive container 25 and the inner cooling jacket 27 which is located in a packaging shell 56 granular bulk material 55.

At the closure end 28 then a small amount of insulating and insulating material 54, such as sand, filled. Now the explosive 5 is introduced with the primer 51 in the container 25, pushed by means of a loading stick to the closure end 28 and caulked to the pipe wall. The remaining cavity is filled with the insulating and insulating 53, the ignition cable 52 are led out of the container 25. The thus filled container 25 is now closed at the filling end 29 as well. Subsequently, the closed explosives container 25 is pushed into the receiving ring 18 of the supply head 11 and fixed there by frictional engagement, wherein the ignition cable 52 are led out through a hole in the rear wall 19 of the supply head 11.
  • insulating and insulating material 54 such as sand
  • the supply head 11, the rear end of the cooling container 1, is made of a stable material, such as cast steel and therefore can be used for several blasts. For this purpose, however, it is necessary that a safety distance of at least 50 mm is maintained between the disintegrating means 5 and the supply head 11, which is to be taken into account in the dimensioning of the length of the disintegrating container 25 and of the charged disintegrant quantity.
  • cooling head receiving tube 18 In addition to the cooling head receiving tube 18 are located with a larger diameter at the supply head 11, two more walls, namely the supply pipe 17, to which the inner tube or the inner cooling jacket 27 of the cooling head 10 and the supply housing 13, to which the outer tube or the cooling head housing 23 are pushed ,
