Description

  The present invention relates to a technology capable of carrying out an RO module using a reverse osmosis (hereinafter referred to as RO) membrane for seawater desalination to a destination by a barge ship while avoiding a load during transportation.

  In desertified areas, seawater desalination facilities are installed. The assembly of the existing desalination equipment involves manufacturing parts such as RO modules, frames, piping, equipment, etc. at the factory, loading these parts on a barge ship and transporting them to the site. In the construction on site, a RO module is placed at a predetermined position using a large lifting machine, and piping is connected to form a desalination apparatus.

  Here, a barge ship does not have a propulsion device itself as a marine transport ship such as a heavy object, and is navigated by a towing boat or a push boat. These barges include a general-purpose type that makes it possible to load any cargo by flattening the loading deck, and those that design the loading deck and hold structure according to the type of cargo (patents) Reference 1). In addition, a configuration and a method for transporting and unloading a load loaded on such a barge ship are also disclosed (see Patent Document 2).

  By the way, the RO module is formed by connecting a plurality of RO units to each other in a factory. In a recent desalination apparatus, the RO module is increased in size, and an extra-large lifting machine is required when carrying in and out of the barge. In some desalination facilities, a large RO module is integrated into the site.

The pore size is about 1 to 2 nm. is there. The RO unit 12 has a reverse osmosis membrane cell (not shown) built in, an inlet (not shown) for introducing filtered water into the cell (not shown), and an output for outputting filtered water from the cell (not shown). A casing 14 having an outlet (not shown) and a discharge port (not shown) for discharging concentrated water from a cell (not shown) is fixed to a frame 16, and further, an introduction port (not shown), an output port ( A pipe (not shown) is connected to an outlet (not shown) and a discharge port (not shown).

  The RO module 10 is an assembly of RO units 12 in an array. In this embodiment, 16 RO units 12 are stacked in an array of 4 rows and 4 columns to form an RO module 10. In the RO module 10, each piping (not shown) extending from the introduction port (not shown) of each RO unit 12, every piping (not shown) extending from the output port (not shown), and from the discharge port (not shown). Each extended pipe (not shown) is connected to a branch pipe (not shown) by welding or clamping (flange connection) so as to be parallel to each other, and adjacent frames 16 are connected by welding or the like.

  As shown in FIG. 1, the barge ship 20 does not have power itself, and is a ship towed by a ship 18 or the like in a state where cargo (RO unit 12 or the like) is loaded. In the barge 20, the deck 22 is formed flat, the RO unit 12 is placed on the deck 22, and the RO module 10 is assembled. Moreover, in order to improve working efficiency, the RO units 12 are arranged in the order in which they are assembled.

  Further, the barges 20 are connected in a plurality of stages in the traveling direction (Y direction), and the adjacent barges 20 are connected by a rope or the like during transportation. On the deck 22 of each barge 20, rails 24 (FIG. 1A and FIG. 1B) on which wheels 36 constituting a later-described portal crane 28 run and wheels 60 constituting a hood 52 run. Rails 26 (not shown in FIG. 1, refer to FIGS. 3 and 4) are laid. The rails 24 and 26 are laid and extended in the Y direction at both ends of each barge ship 20 in the X direction. In this case, the rail 24 used for the portal crane 28 is laid inside the rail 26 used for the hood 52. When the RO module 10 is assembled, the adjacent barges 20 are brought into direct contact with each other, and the ends of the rails 24 and 26 of each barge 20 are connected to the ends of the rails 24 and 26 of the adjacent barge 20 respectively. Rails 24 and 26 are connected in a straight line in the Y direction on a plurality of barges 20 (deck 22) connected in multiple stages. As a result, the portal crane 28 and the hood 52 can move in the Y direction across the barge 20 connected to other stages.

  FIG. 3 shows a schematic diagram of the portal crane of the present embodiment, FIG. 3 (a) is a front view, and FIG. 3 (b) is a side view. The portal crane 28 assembles the RO module 10 by lifting the RO unit 12. The portal crane 28 is arranged at the same interval as the width of the rail 24 when viewed from the Y direction, has a wheel 36 at the lower end, and connects the two legs 30 and the two legs 30 that can be adjusted in height. The beam unit 48 extends in the horizontal direction (X direction), and the crane unit 50 is connected to the beam unit 48 and is slidable in the longitudinal direction (X direction) and can lift the RO unit 12. Here, between the leg part 30 and the beam part 48, the crane part 50 shall acquire the rigidity which can endure enough even if it lifts RO unit 12. FIG. The length of the beam portion 48 (the width of the rail 24) is slightly smaller than the width of the barge 20 in the X-axis direction, and the RO unit loaded when the portal crane 28 moves in the Y direction. 12 is not interfered.

  The leg portion 30 is provided with a support column 32 that constitutes the upper portion and a vertical adjustment mechanism 34 that constitutes the lower portion and adjusts the height direction of the leg portion 30. The vertical adjustment mechanism 34 has a hollow prism (which may be a cylinder) structure having a wheel 36 at the lower end and an opening at the upper end, and is arranged in the Y-axis direction with the longitudinal direction oriented in the vertical direction (Z direction). The lower member 38, a first connecting member 40 having a longitudinal direction in the Y direction and connecting the two lower members 38, and a cross-section having a shape following the opening of the lower member 38, can be inserted into the lower member 38, respectively. Two upper members 42, a second connecting member 44 having a longitudinal direction in the Y direction and connecting the upper member 42 and supporting the support column 32, and a second connecting member fixed to the first connecting member And a jack 46 for lifting 44. Therefore, the height position of the 2nd connection member 44, the upper member 42 connected to this, and the support | pillar 32 can be adjusted by adjusting the feeding amount of the jack 46. FIG.

  The lower member 38 is provided with a plurality of bolt holes 38a, and the upper member 42 also corresponds to the change in the relative position with the lower member 38 and is arranged in the height direction so as to communicate with the bolt holes 38a of the lower member 38. Bolt holes (not shown). Therefore, the height of the portal crane 28 (Z direction) can be adjusted by adjusting the height with the jack 46 and then inserting a bolt (not shown) into the bolt hole 38a and tightening the bolt. The height position is fixed. The height of the portal crane 28 is adjusted to be lower than that of the hood 52 described later in both cases of transportation and assembly. When the RO unit 12 is transported, the RO unit 12 is lowered using the vertical adjustment mechanism 34 so as to have the same height as the RO unit 12. Further, when the RO module 10 is assembled, the crane unit 50 is raised using the vertical adjustment mechanism 34 so that the lower end of the crane unit 50 is higher than the upper end of the RO module (including the height of the pedestal described later).

  The wheels 36 are arranged so that they can run on the rails 24. As a result, the entire portal crane 28 can be moved in the Y direction along the rail 24. Further, since the lower member 38 is fixed at a certain interval in the Y direction in the vertical adjustment mechanism 34, the stability of the portal crane 28 in the Y direction can be improved.

  4A and 4B are schematic views when the hood of the present embodiment is expanded and contracted. FIG. 4A shows an extended state and FIG. 4B shows a folded state. FIG. 5 shows a schematic diagram when the height of the hood of this embodiment is changed. FIG. 5A shows a case where the height is lowered, and FIG. 5B shows a case where the height is raised.

  The hood 52 is mounted on the barge ship 20 and has a bellows structure that can expand and contract in the Z direction, and forms an internal space 54 that includes the RO unit 12 and the RO module 10 loaded on the barge ship 20. . The hood 52 has a reverse U-shaped shape having the same width as the width of the rail 26 when viewed from the Y direction, a plurality of frames 56 arranged side by side in the Y direction, a non-woven fabric, and the like. The inner space 54 is formed by being connected to each frame 56 so as to cover the whole 56, and a hood cloth 58 having a bellows structure that can expand and contract in the Y direction is provided. A wheel 60 is provided at the lower end of the frame 56 and can travel on the rail 26. Since the rail 26 is connected in a straight line on the barge ship 20 (deck 22) connected in multiple stages like the rail 24, the hood 52 moves across the barge ship 20 connected in multiple stages through the rail 26. Can do.

  A horizontal bar 62 having a telescope structure that has a longitudinal direction in the Y direction and can be expanded and contracted in the longitudinal direction is attached to the frame 56. Both ends of the horizontal bar 62 are fixed at predetermined height positions of the frames 56 at both ends in the Y direction. On the other hand, a ring (not shown) through which the horizontal bar 62 is inserted at a predetermined height is attached to the frames 56 other than the frames 56 at both ends in the Y direction, and these frames 56 are inserted into the rings (not shown). The support in the Y direction is made by the rod 62. Further, the horizontal bar 62 is fixed at the two height positions of the frame 56 by the fixing method described above. As a result, the stability of the frame 56 in the Y direction is improved, and the horizontal bar 62 can be contracted at the same time as the frame 56 and the hood cloth 58 are folded in the Y direction.

  In addition, for example, the portion sandwiched between the second horizontal bars 62 in the second stage from the height direction of each frame 56 is telescopic structure that can be expanded and contracted in the height direction (Z direction) like the horizontal bars 62 described above. (Not shown). Therefore, when the interval between the plurality of frames 56 and the hood cloth 58 are fully extended in the Y direction, the hood cloth 58 can be easily folded in the height direction as shown in FIG. Can be lowered. If the strength of each frame 56 is insufficient due to the telescope structure described above, support rods (not shown) are placed between the two horizontal bars 62 at predetermined intervals in the Y direction when the RO module 10 is assembled. The horizontal bars 62 may be connected and fixed by interposing them.

  Further, an air conditioner (not shown) is provided inside the hood 52, and the internal space 54 formed by the hood 52 can be maintained at a constant temperature. An air conditioner (not shown) is attached to the hood 52 and is movable with the movement of the hood 52. In the present embodiment, it is sufficient that the length of the hood 52 in the Y direction has a dimension about the length of the one barge ship 20 in the Y direction. The other barge ship 20 is covered with, for example, a sheet (not shown) that covers the entire barge ship 20 or the entire loaded RO unit 12, and an internal space 54 formed by the hood 52 and an internal space formed by the sheet (not shown). By providing a flexible duct (not shown) that connects to 55, the temperature of the RO unit 12 loaded on the barge ship 20 without the hood 52 can be adjusted. It is desirable that the temperature of the RO unit 12 be adjusted so that it does not exceed 40 degrees during transportation and assembly. Thereby, the physicochemical change of the polymer fiber of the membrane material can be suppressed, and the deterioration of the performance of the RO unit 12 can be suppressed.

  Thus, since the RO module 10 is assembled after the barge ship 20 is called at another port of the transport destination, it is possible to carry it out to the transport destination while avoiding a load on the RO module 10. Moreover, since it can transport in the state which maintained the appropriate temperature of RO unit 12, it becomes possible to suppress degradation of the performance of RO unit 12.

  FIG. 6 shows a schematic diagram when the RO module is carried out in the present embodiment. The assembly of the RO module 10 is performed on a pedestal (not shown) that is arranged on the deck 22 and has the same size as the lower surface of the RO module 10 in plan view. The pedestal (not shown) can insert the conveyance carriage 64 by jacking up a first gap (not shown) into which a jack (not shown) for lifting the RO module 10 can be inserted together with the pedestal (not shown). It has a possible second gap (not shown).

  The transport carriage 64 can travel between the barge ship (on the deck 22) and the berthing destination of the barge ship 20 (is capable of self-propelling), and carries the RO module 10 out of the barge ship 20. Further, a bridge (not shown) through which the transport carriage 64 can cross is hung between the barge ship 20 and the berthing destination. Therefore, after assembling the RO module 10 on a pedestal (not shown), a jack (not shown) is inserted into the first gap (not shown) and the RO module 10 is jacked up together with the pedestal (not shown). The conveyance carriage 64 is inserted into the formed second gap (not shown), the jack (not shown) is removed, the pedestal (not shown) and the RO module 10 are placed on the conveyance carriage 64, and the bridge (not shown) is interposed. Thus, the RO module 10 can be carried out to the pier. In addition, in order to make conveyance by the conveyance truck 64 easy in the harbor of a docking destination, you may provide the track | truck 66 for conveyance trucks which the conveyance carriage 64 drive | works.

  FIG. 7 shows a flowchart of the assembly procedure of the RO module of the present embodiment. The assembly procedure of the RO module of this embodiment will be described. The RO module assembling method of this embodiment is an assembling method of the RO module 10 that assembles the RO module 10 by using a plurality of RO units 12, and is a portal crane 28 that lifts the RO unit 12 in contact with one port. A plurality of RO units 12 are loaded on a barge ship 20 mounted with a slab, the barge ship 20 is towed to another port, the RO unit 12 is lifted by the portal crane 28, and the RO module 10 is mounted on the barge ship. 20 to assemble. The plurality of RO units 12 loaded on the barge ship 20 are covered with a hood 52 provided on the barge ship 20, and an internal space formed by the hood 52 and including the plurality of RO units 12. 54 temperature adjustment is performed.

  Further, the plurality of RO units 12 are arranged on the barge ship 20 in the order in which the RO modules 10 are assembled, and when the barge ship 20 is towed, the height of the portal crane 28 and the height of the hood 52 are determined. The hood 52 is adjusted to be lower than that when the RO module 10 is assembled, and the hood 52 is formed to be movable and extendable in the direction in which the RO units 12 are arranged. The plurality of RO modules 10 are sequentially exposed from the internal space 54 by moving or folding the hood 52.

  Then, the barge ship 20 is connected in a plurality of stages in the direction of traveling with the assembly of the RO module 10 of the portal crane 28, and the portal crane 28 and the hood 52 are moved onto the next barge ship 20. After that, the barge ship 20 from which the RO module 10 has been unloaded is separated from the next-stage barge ship 20.

  First, the RO unit 12 is manufactured at the factory. Then, the RO unit 12 is transported to the harbor and loaded on the barge ship 20, and the loaded RO unit 20 is covered with a hood 52 to adjust the temperature. At this time, the RO unit 12 on the barge ship 20 without the hood 52 is covered with, for example, a sheet (not shown) that covers the entire barge ship 20, and an internal space 54 formed by the hood 52 and an interior formed by the sheet (not shown). The space 55 is connected by a flexible duct (not shown). The hood 52 is folded in the height direction in order to reduce the internal space 54 formed by the hood 52, and the gate crane 28 is folded in the height direction so as not to interfere with the folded hood 52. In this state, the barges 20 are connected in a row with a rope or the like, and the barges 20 are towed by the ship 18 and are transported by sea to a destination port (a port near the installation site). Thus, by reducing the volume of the internal space 54 formed by the hood 52 during transportation, the volume for temperature adjustment can be reduced, and the power used for temperature adjustment can be reduced.

  Next, when arriving at the destination port, the barge ship 20 that has towed the barge ship 20 or another ship is pushed in the berthing direction, and the barge ship 20 with the hood 52 and the portal crane 28 mounted thereon. Bring to the berthing destination. The adjacent barges 20 are brought into contact with each other, and rails 24 and 26 provided for each barge 20 are connected in a straight line. On the other hand, the hood 52 and the portal crane 28 are raised to a height position for assembling the RO module 10, and the RO unit 12 on the barge 20 that has berthed is lifted by the portal crane 28 and placed on the deck 22. The RO module 10 is assembled (in the internal space 54) on the pedestal (not shown).

  After assembling the RO module 10, the hood 52 is contracted in the Y direction (offshore side) to expose the RO module 10 from the internal space 54. Then, a jack (not shown) is inserted into the pedestal (not shown), the RO module 10 is lifted together with the pedestal (not shown), and the transport carriage 64 is inserted under the pedestal (not shown). Remove the jack (not shown) from the pedestal (not shown) and place the RO module 10 together with the pedestal (not shown) on the transport carriage 64 and through the bridge (not shown) hung between the dock and the barge 20 10 is carried out and moved to the installation site of the desalination facility at the pier. By using such a transport carriage 64, the RO module 10 can be efficiently transported to the installation site of the desalination facility.

  Next, the hood 52 and the portal crane 28 are moved from the barge ship 20 where the RO unit 12 is emptied to the next barge ship 20 via the rails 26 and 24, respectively, and the barge where the RO unit 12 is emptied. The ship 20 is removed from the berthing destination and the next-stage barge ship 20 is berthed. Thereby, since the barge ship 20 which RO module 10 assembles can be berthed, RO module 10 can be carried out efficiently.

  Then, the sheet (not shown) covering the next-stage barge ship 20 is removed, and the hood 52 is expanded again in the Y direction, so that the internal space 54 covering the RO unit 12 and the portal crane 28 on the next-stage barge ship 20 is formed. Form again. Alternatively, the hood 52 is not spread all at once in the Y direction, and the sheet (not shown) is gradually peeled off as the RO module 10 is assembled, and the hood 52 is gradually spread in the Y direction correspondingly, or the sheet (not shown) is expanded. It may be moved in the peeling direction. Then, the RO module 10 is assembled and carried out at the next barge 20. Thereafter, the process is repeated until the assembly and unloading of the last stage barge 20 are completed.

  Therefore, even when the RO module 10 is assembled, the temperature of the RO module 10 immediately before being unloaded from the barge ship 20 and the RO unit 12 before being assembled are adjusted, and only the RO module 10 to be unloaded is exposed to the outside. Therefore, deterioration of the performance of the RO module 10 can be suppressed with high accuracy, and the volume of the internal space 54 formed by the hood 52 (including the internal space formed by the sheet) can be reduced as the RO module 1 is carried out. Therefore, the power used for temperature adjustment can be reduced even when the RO module 10 is assembled and carried out.

  The present invention can be used as a barge ship, an RO module assembly system, and an RO module assembly method capable of transporting the RO module to a transport destination at low cost without applying a load to the RO module.
