Definitions
- the invention relates to a pipeline for conveying liquefied gas, in particular on so-called LNG tankers, so tankers for the transport of liquefied natural gas.
- ERDC / CRREL TR-08-14 describes that it is well known to cut off ice on the pipes and fittings with hammers. In order to avoid the damage occurring and the great effort required for this purpose, it has been proposed to surround the components located on the ship deck with plastic plates and to defrost them in some form by vibration. This technology has been found unsatisfactory. The invention is therefore based on the object to prevent the formation of ice on the pipes and to facilitate ice removal.
- the vibrating tube surrounds the pipe provided with a cold insulation for the transport of liquefied gas at a distance, so that a cavity is formed.
- the vibration tube itself can ice. It is freed from the ice by the vibration.
- the only in each case partially formed vibration pipes are connected together according to claim 1 by means of a sliding connection, which may be formed according to claim 3 as a vibrating pipe connector shell.
- the tube is supported in the region of the sliding connection by means of a bearing on the ground.
- a reliable vibration transmission from the vibrator to the vibration tube is ensured by the measures according to claim 5.
- Fig. 4 is a cross section through the pipeline adjacent to a
- FIG. 7 shows a detail corresponding to VII from FIG. 6,
- FIG. 8 shows a cross section through the detail VII in FIG. 7 corresponding to the section line VIII-VIII in FIG. 7, FIG.
- Fig. 9 is a plan view of a pipe with a pipe bend
- Fig. 10 is a plan view of a pipe with a pipe branch branch
- Fig. 11 shows a pipe with a fitting in side longitudinal view.
- a LNG pipe laid on a deck 1 of a ship or other subsoil comprises an LNG pipe 2 with a cold insulation 3 made of insulating material, which generates a heat flow from outside into the pipe 2 should prevent.
- the abbreviation LNG pipe 2 is used below for a pipe in which liquid Natural gas is promoted.
- LNG stands for Liquid Natural Gas.
- the LNG tube 2 sheathed with the cold insulation 3 is in turn surrounded by a protective tube or sheath designed as a vibration tube 4, which - as can be seen, for example, in FIGS.
- the vibration tubes 4 are formed by half-shells 6, 7 consisting of sheet metal, which are connected to each other by means of a flange connection 8, as can be seen in FIG. 4.
- the half-shells 6, 7 Since the half-shells 6, 7 have a finite length, they are each connected to one another by means of a pipe-section-shaped vibrating pipe connector shell 9, in which the individual sections of the vibrating pipe 4 formed by interconnected half-shells 6, 7 are sealed in the manner of a sliding bearing are guided, as shown in FIG. 3 can be removed.
- the vibrating pipe connector shells 9 in turn consist of connector half-shells 9a, 9b, which are interconnected by means of flange connections 9c.
- a bearing 10 is arranged for the coated with a cold insulation 3 LNG pipe 2, the lower half of the bearing shell 11 and its upper half bearing shell 12 with a
- Sheet metal jacket 3 surround a covered cold insulation 3 and are connected to each other by means of a flange 10a.
- the lower bearing half-shell 11 is slidably supported on the deck 1 by means of a bearing shoe 13.
- the bearing shoe 13 passes through a lower opening 14 in the connector shell 9, where an ice water drain 15 is provided, as shown in FIG. 2 can be removed.
- the half-shells 6, 7 and the half-rings 16, 17 are - as can be seen in particular from FIG. 7 - connected to one another in a common flange connection 19.
- the vibrator ring 18 designed as a commercial pneumatic vibrator vibrator 21 is arranged, which is fixedly mounted on a support plate 22, which in turn is in fixed vibration connection with the upper half ring 17 of the vibrator ring s 18. Vibrations of the vibrator 21 are thus transmitted to the vibrator ring 18.
- the vibrator 21 is surrounded by a vibrator housing 23 as a protective housing.
- the compressed air supply of the vibrator 21 via a compressed air main line 24, which is arranged in the cavity 5 and is guided through the entire pipeline.
- a compressed air connection line 25 leads to each vibrator 21.
- An exhaust air line 26 in turn leads out of the vibrator 21 into the open air.
- the vibrator ring 18, namely the lower half-ring 16 is supported on the deck 1 via a bearing 28 consisting of rubber buffers 27, the rubber bumps 27 in turn being supported on an underside. support the lower support plate 29 which is attached to the lower half-ring 16 of the vibrator ring 18.
- a vibration unit 30 is formed, which is substantially the corresponding portion of the vibration tube 4, the vibrator 21 with vibrator ring 18th and the associated details.
- Such a vibration unit 30 is supported via the vibrator ring 18 and the bearing 28 at its center.
- a bearing 10 of the LNG pipe 2 is provided on one side of the pipe bend 31.
- the sheathing of the LNG tube 10 by a corresponding to the pipe bend 31 curved vibration tube 32 is formed at its ends as a respective sliding bearing 33, 34, so as in the area of the vibrating tube connecting shells 9.
- the arrangement is such that the vibrators 21 with vibrator rings 18 are arranged on the straight-line pipe sections immediately adjacent to the two ends 35, 36 of the curved vibration pipe 32.
- the LNG pipe 1 has a pipe branch 37, a so-called T-piece, then the corresponding pipe branch vibration pipe 38 at all three ends 39, 40, 41 in principle like a sliding bearing 42, 43, 44 formed. Adjacent to all three ends 39, 40, 41 vibrator rings 18 are arranged with vibrators 21 in the vibrating tube 4 and in the two branching vibrating tubes 4a and 4b.
- the branch pipe vibration pipe 38 is supported by a bearing 10 in the region of its end 39 adjacent to the LNG pipe 2. If - as shown in FIG.
- a valve 45 so a valve or a slider is arranged at both ends of the fitting 45 surrounding insulating housing 46 each have a valve-vibration tube 47, 48 are provided , which receive the adjacent vibrating tube 4 in the manner of sliding bearings 49, 50.
- Both fitting vibration pipes 47, 48 are each supported by means of bearings 10 on the deck 1.
- vibrator rings 18 Adjacent to the ends 51, 52 of the valve-vibration pipes 47, 48 4 vibrator rings 18 are provided with vibrators 21 on the opening into them vibration pipes, so that the hollow insulating housing 46 can be set in vibration.
- the insulating housing 46 has a removable cover 53.
- the vibration tube 4 and possibly the curved vibration tube 32, or possibly the branch pipe 37 and the pipe branch vibrating pipe 38 and possibly the insulating housing 46 are set in vibration by the on ice is removed and removed.
