Definitions

  • the present invention relates to the technical field of water abrasive suspension blasting (WASS) and there specifically the bypass principle for generation by WASS.
  • WASS water abrasive suspension blasting
  • Water abrasive suspension blasting is used, for example used in dismantling technology under and above water.
  • Example shell jackets disassembled to avoid flying sparks to be able to remove and dispose of the explosive contained therein.
  • proven has the abrasive water suspension blasting also in the disposal of nuclear power plants, especially when disassembling the pressure vessel.
  • Other areas of application are offshore technology, as well as in the petrochemical industry, when it comes to disconnection in potentially explosive environments.
  • the devices operating on the bypass principle essentially exist from a high pressure pump, which uses water as a carrier liquid in a Main line with throttle element and parallel to a secondary line (bypass) promotes.
  • the secondary line opens into a pressure vessel in which the abrasive is located, with the liquid flow conducted in the secondary line passes through the pressure vessel, takes abrasive there and over a Line from the pressure vessel is fed back to the main line. be wearing this suspension is fed through a discharge nozzle, which has a flexible Pipe possibly several hundred meters away from the device can be arranged.
  • the amount of the Available abrasives depend on the size of the pressure vessel. If the abrasive in the pressure vessel has been used up, must the pressure vessel is filled and the water abrasive suspension blasting while be interrupted this time.
  • a generic device is known from EP 0 276 219 B1, in which only a pressure vessel is provided before the high pressure pump is filled switched off and the suspension jet is interrupted.
  • a circulation path is provided within the system, in which the abrasive together with liquid from a storage container into the pressure container and from there is pumped back to the storage container.
  • the cable duct designed by the pressure vessel so that the abrasive settles in this, whereas the liquid returns to the Storage container is guided.
  • the device-like structure of the main stream uncoupled circulation route for filling the pressure vessel is also high.
  • the fittings provided within the circulation route must be constructive be designed in such a way that their function is reflected in that inevitably deposited abrasives are not impaired.
  • the task of the present invention is based on this prior art to create a method for filling a pressure vessel with that this is simple, fast and with little device effort can be filled.
  • a corresponding device be created with which this method can be carried out, which is inexpensive the manufacture and constructively largely against abrasive deposits is protected.
  • the basic idea of the present invention is based on the prior art Technology known circulation path for filling the pressure vessel with abrasive to do without entirely and instead to provide gravity support, that does without an expensive and wear-prone pump and that into the device inexpensively by means of a small number of shut-off valves is integrable.
  • a hopper is provided, by from the abrasive contained therein by gravity into the pressure vessel arrives.
  • the filling container must therefore be arranged above the pressure container be, the abrasive via a down pipe from the lower Area of the filling container leads to the upper area of the pressure container, in the Pressure vessel arrives.
  • the abrasive to be filled can be used as such from the downwardly tapered filling container into the downpipe and then get into the pressure vessel, is convenient but also the abrasive in the filling container a carrier liquid such as Example water added to the gravity-related conveying process facilitate.
  • a stop valve in the downpipe intended to prevent the suspension or carrier liquid during normal conveying operations.
  • a corresponding shut-off valve must then also be in the drain line be provided if such is provided. It can be used as a drain line serve a part of the secondary line, which opens into the pressure vessel. It is understood that the shut-off valve is then outside the area of the secondary line must lie. This measure can reduce the number of in the pressure vessel opening lines are minimized, which is already static Reasons is an advantage.
  • the downpipe between the filling tank and pressure tank should be largely run vertically, because then the weight of the abrasive to be refilled acts in the direction of conveyance and avoids clogging of the lines can be.
  • System-related it is useful if the down pipe from The bottom of the filling container is essentially vertical and straight in the lid or the top of the pressure vessel opens. However, it can be static or it may be necessary for other reasons to relocate the place of muzzle. In these cases, care must be taken to ensure that the outlet pipe ends in the Pressure vessel as far up as possible and the outlet of the downpipe into the Filling containers are as far down as possible.
  • this secondary line as essentially vertical riser pipe formed within the pressure vessel is that at least in its mouth area in the middle with respect to the Bottom rejuvenation should be arranged.
  • shut-off valves in a row in the downpipe and have a flushing line connected between them. Then at a jam of abrasive in the downpipe first of all the filling container Closer shut-off valve are closed, after which carrier liquid via the flushing line is introduced into the system under pressure, so that at the end of the Flushing process the shut-off valve close to the pressure vessel including downpipe as well as the drain line and valve are free of abrasive.
  • shut-off valves namely the pressure vessel side Shut-off valve in the downpipe and the other valve in the drain line closed.
  • the latter valves are high pressure valves that due to its design, it is particularly susceptible to deposits of abrasive agents the valve seats.
  • the filling container is designed as an interchangeable container is particularly advantageous is because then only an empty one is replaced by a full one Filling container is to be replaced without using abrasive within the device is to be handled.
  • the device shown in the figure is used to generate a beam of Suspension of a carrier liquid, usually water, and an abrasive, for example corundum or river sand under high pressure.
  • the carrier liquid 1 is made from a container 2 or from a (not shown) Line network fed a high pressure pump 3, which is typically a Pressure between 200 and 2000 bar and more generated on the outlet side.
  • a Line 4 is the high-pressure carrier liquid 1 from the pump 3 through a check valve 5 in parallel in a main line 6 and a Branch line 7 promoted.
  • a throttle element 8 is provided in the main line, that is dimensioned and adjusted so that in addition to one in operation in the Main line 6 forming main stream leading through the secondary line 7 Side stream sets, the abrasive in a pressure vessel 10 9 records, this feeds the main stream and then as a total stream at a discharge nozzle 11 a jet emerging under high pressure Form suspension of carrier liquid 1 and abrasive 9.
  • the secondary line 10 points in the conveying direction 12 of the flowing through it In addition to a shut-off valve 13 and a safety device 14, which opens when a predetermined maximum pressure is exceeded.
  • the Branch line 7 opens into the top of the pressure vessel 10.
  • the pressure vessel 10 has an approximately conical bottom 15, over whose lowest point opens a riser 16 at a short distance, which over a line 17 is connected to the main line 6.
  • Line 17 is part of the Secondary line 7.
  • After merging the main and secondary line 6.7 then flows the suspension formed from carrier liquid 1 and abrasive 9 via a line 28 to the discharge nozzle 11.
  • the line 28 connects the in Substantially stationary part of the device with the movably arranged part Discharge nozzle 11 and can be several hundred meters long. Stationary in the sense of the invention means that the device stands still during operation, in principle, however, this is portable, for example on a vehicle or arranged in a container or support frame.
  • a filling container 18 is provided which is connected to the pressure vessel 10 via a down pipe 19.
  • the downpipe 19 is arranged essentially vertically and opens into the Top of the pressure vessel, but a short distance below the Top inside, ie below the junction of the branch line 7 in the Pressure vessel 10.
  • a high pressure shut-off valve 20 and a further shut-off valve 21 assigned to the filling container 18 is provided. Between these two check valves 20 and 21 connected in series opens a flushing line 22.
  • the filling container 18 is an interchangeable container trained and can together with the shut-off valve 21 via the clutch 23 be separated from the rest of the device to make an empty one replace full fill container 18 or the fill container for transportation purposes to remove the device.
  • the flushing line 22 is via a not shown Hose coupling connected and can therefore also from Filling container 18 are separated.
