Definitions
- the present invention relates to the technical field of water abrasive suspension blasting (WASS) and there especially the bypass principle for the production from WASS.
- WASS water abrasive suspension blasting
- the water abrasive slurry jetting used in dismantling technology under and over water.
- Example bullet shells disassembled to avoid flying sparks Remove and dispose of explosives located therein.
- proven water abrasive suspension blasting has also been found in the disposal of nuclear power plants, especially when disassembling the pressure vessel.
- Further applications are the offshore technology, as well as in the field of the petrochemical industry, when it comes to disconnecting in an explosive environment.
- the devices operating on the bypass principle essentially consist of from a high-pressure pump, which water as a carrier liquid in a Main line with throttle body and parallel in a secondary line (bypass) promotes.
- the secondary line opens into a pressure vessel in which the abrasive is located, wherein the guided in the secondary line liquid flow passes through the pressure vessel, there takes along abrasive and a Line from the pressure vessel is fed back to the main line. be wearing
- This suspension is via a discharge nozzle, which has a flexible Lead, if necessary, several hundred meters away from the device can be arranged.
- the carrier liquid from a reservoir or from the water supply network usually in sufficient quantity for continuous operation of the Device is available for a long time, the amount of the Available abrasive depending on the size of the pressure vessel. If the abrasive contained in the pressure vessel is used up, must the pressure vessel is filled and the water abrasive suspension jets during be interrupted this time.
- a generic device is known in the only a pressure vessel is provided, before filling the high-pressure pump switched off and thus the suspension jet is interrupted.
- a circulation path is provided, in which the abrasive together with liquid from a reservoir into the pressure vessel and is pumped from there back to the reservoir.
- the cable implementation designed by the pressure vessel so that the abrasive in this settles, whereas the liquid again in the return to Reservoir is performed.
- the device-like construction of the main stream decoupled circulation path for filling the pressure vessel is also high.
- the valves provided within the circulation path must be constructive be designed so that they are in their function through that there too inevitably abrasive abrasives are not impaired.
- the present invention has the object to provide a method for filling a pressure vessel, with this easy, fast and with little device overhead can be filled.
- a corresponding device be created, with which this method is executable, which is inexpensive in the production and constructive largely against Abrasivstoffablagerache is protected.
- the basic idea of the present invention is based on the state of the art Kunststoffer known circulation path for filling the pressure vessel with abrasive to refrain altogether and to provide gravity support instead, which manages without an expensive and wear-prone pump and the by means of a small number of shut-off valves cost in the device is einkliederbar.
- a filling container Hopper
- the filling container must therefore be arranged above the pressure vessel be, wherein the abrasive agent via a downpipe, from the lower Area of the filling container leads to the upper area of the pressure vessel, in the Pressure vessel arrives.
- the abrasive to be filled in as such from the downwardly tapered filling container in the down pipe and then get into the pressure vessel is expediently
- the abrasive in the filling a carrier liquid such as Example water added to the gravity-induced conveying process facilitate.
- the abrasive contained in the pressure vessel at the end of the operation by Water is replaced, it is not empty when refilling with abrasive but water-filled, so it's not just the abrasive in the pressure vessel filled, but also the volume corresponding volume Water are led out. In the simplest form, this can also be done by the Downpipe itself. However, preferred is a separate line to Removal of the displaced carrier liquid provided so that when filling the Gravity-promoted mass flow of the abrasive not by the otherwise in Counter direction ascending current of the displaced carrier fluid braked becomes. So it can be essential when providing a separate drain line higher filling speeds can be achieved.
- shut-off valve in the down pipe intended.
- a corresponding shut-off valve must then also 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 then outside the area of the secondary line must lie. By this measure, the number of in the pressure vessel opening lines are minimized, which is already static Reasons is advantageous.
- the downpipe between filling tank and pressure vessel should be largely run perpendicular, because then the weight of the replenished abrasive acting in the conveying direction and blockages of the lines avoided can be. Due to the system, it is expedient if the downpipe from Bottom of the filling container in essence vertical and straight into the lid or the top of the pressure vessel opens. It can, however, be static or for other reasons be required to relocate the mouth. In these cases, make sure that the mouth of the downpipe in the Pressure vessel as far above and the mouth of the downpipe in the Filling tank as far as possible below.
- the pressure vessel on the bottom side in the manner of a Funnel, that is, to run downwards and the part of the secondary line, which directs the abrasive into the main stream to form so that this Part of the laxative branch line with small distance above the ground empties. It is particularly advantageous if this laxing secondary line as formed substantially vertical riser within the pressure vessel is that centered at least in its mouth area in relation to the Soil rejuvenation should be arranged.
- shut-off valves in the downpipe in series one behind the other and connect a purge line in between. Then you can join a jam of abrasive in the downpipe first that the filling container Closer shut-off valve are closed, after which via the purge line carrier liquid under pressure is introduced into the system, so at the end of the Rinsing the pressure vessel near the shut-off valve including down pipe as well as the drain line and valve is free of abrasive.
- shut-off valves namely the pressure tank side Shut-off valve in the downpipe and the other valve in the drain line closed.
- the latter valves are high pressure valves, the Due to the design, it is particularly susceptible to abrasive deposits the valve seats are.
- the filling container is designed as a swap body is, because then to exchange only an empty against a full Fill container is to be replaced, without that within the device with abrasive to handle.
- the device shown in the figure is used to generate a beam of a Suspension of a carrier liquid, usually water, and an abrasive, For example, corundum or river sand under high pressure.
- the carrier liquid 1 is taken from a container 2 or from a (not shown) Line network of a high-pressure pump 3, which typically has a Pressure generated between 200 and 2000 bar and more on the output side.
- a Line 4 is the high-pressure carrier fluid 1 from the pump 3 through a check valve 5 in parallel in a main line 6 and a Secondary line 7 promoted.
- a throttle body 8 is provided, that is dimensioned and adjusted so that in addition to one in operation in the Main line 6 forming a main current through the secondary line 7 leading Adjusts stream, which is located in a pressure vessel 10 Abrasivstoff 9, this feeds the main current and then as a total current at a discharge nozzle 11 exiting at high pressure jet a Suspension of carrier liquid 1 and 9 to form abrasive.
- the secondary line 10 has in the conveying direction 12 of the flowing through them Maustroms a shut-off valve 13 and a safety device 14, which opens when a predetermined maximum pressure is exceeded.
- the Secondary line 7 opens into the top of the pressure vessel 10.
- the pressure vessel 10 has an approximately tapered bottom 15, over whose lowest point at a short distance a riser 16 opens, the over a line 17 is connected to the main line 6.
- the line 17 is part of Secondary line 7.
- the suspension then formed from carrier liquid 1 and abrasive flows 9 via a line 28 to the discharge nozzle 11.
- the line 28 connects the im Substantially stationary part of the device with the movable arranged 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 transportable, for example on a vehicle or arranged in a container or support frame.
- a filling container 18 is provided, which is connected via a downpipe 19 to the pressure vessel 10.
- the downpipe 19 is arranged substantially vertically and opens in the Top of the pressure vessel, but with a small distance below the Top inside, so below the junction of the secondary line 7 in the Pressure vessel 10.
- a Hochdruckabsperrventil 20 is provided in the downpipe 19 as well another the filling container 18 associated shut-off valve 21 is provided. Between these two series-connected shut-off valves 20 and 21 opens a purge line 22.
