Definitions

  • the invention relates to a membrane module for a membrane separation plant of the type specified in the preamble of claim 1. Both a micro or ultrafiltration system and a reverse osmosis system can be considered as membrane separation systems.
  • the pressure tubes of membrane modules are either made of metal or plastic, which may have glass fiber reinforcement.
  • the connections for the raw water supply on the one hand and for the permeate and concentrate or residual water discharge on the other must be attached to the ends of the pressure pipes. This is usually done with the aid of connecting bodies which are inserted into the pipe end and which have threaded bores or line bushings for the connection of liquid lines and adapter pieces for connection to the membrane element arranged inside the pressure pipe.
  • Tubes made of glass fiber reinforced plastic are suitable for this purpose, which are produced, for example, by winding a strand of glass fiber impregnated with a hardening synthetic resin on a winding mandrel.
  • a tube can be made more or less thick-walled and can thus be adapted to the requirements for pressure resistance.
  • the connection technology common with metal pipes can no longer be used with these thin-walled GRP pipes, since this does not provide sufficient sealing in the area of the connection body.
  • reinforcement sleeves are used there, which are fastened, for example with the aid of a threaded or claw coupling, to the outside of the pipe end in the region of the connecting body.
  • the reinforcement sleeve has the task of fixing the diameter of the pressure pipe in the connection area so that tightness is ensured.
  • a counterpart must be attached to the GRP pressure pipe, for example a threaded ring for a screw connection or a claw ring for a claw coupling.
  • the prefabricated GRP pipe must be mechanically prepared on the surface, ie in particular to be ground and roughened to produce the exact fit. This manufacturing process requires several
  • the invention has for its object to improve the membrane module of the type specified in the introduction, that despite the use of a relatively thin-walled pressure tube, preferably made of glass fiber reinforced plastic, there is the possibility of an immediate pressure-tight attachment of the connection bodies without the aid of sleeves and the like.
  • the solution according to the invention is based on the idea that a reliable connection of the connecting body requires, at least at the ends of the pressure pipe, a dimensionally stable part which already contains the precautions required for the attachment, such as internal thread or locking grooves.
  • an annular insert part is positively integrated into the pressure pipe ends in the course of the manufacture of the pressure pipe.
  • annular insert is arranged on the inside of the pressure pipe ends for the pressure-tight reception of the connector body, which is overlapped on its outer surface by the plastic sleeve of the pressure pipe and is connected flatly to the latter.
  • the insert can be designed, for example, as a precision turned part made of plastic or metal or as an injection molded part.
  • the plastic sleeve of the pressure tube consists of glass fiber strands or strips soaked with a hardened synthetic resin, which are wound spirally and in multiple layers to form a cylinder and enclose the inserts at the pressure tube ends to form an annular thickening.
  • the preformed annular inserts are expediently pushed onto a winding mandrel and fixed there at a distance from one another which corresponds approximately to the length of the pressure pipe to be produced.
  • the glass fiber strand or the glass fiber ribbon is wound onto the outer surface of the inserts in the course of being wound onto the winding mandrel, forming a flat, form-fitting connection.
  • an adhesion promoter can be applied to the preferably roughened outer surface of the insert parts or provided with anchoring ribs or knobs before winding up the glass fiber strand.
  • the pressure pipe system according to the invention can be used in reverse osmosis, nanofiltration, ultrafiltration and microfiltration. It is suitable for the installation of the commercially available winding elements with different lengths and diameters and allows different fastening options for the connection bodies. A lateral arrangement of the connections on the high-pressure side for the feed water supply and the residual water or concentrate discharge can also be provided.
  • the pressure pipes are corrosion-resistant and save material and can be manufactured inexpensively.
  • Fig. 1 to 4 different embodiments of the closure and connection end of a membrane module in an axially sectioned view.
  • the membrane modules shown in the drawing are intended for use in membrane separation systems for water treatment.
  • the membrane module essentially consists of a cylindrical pressure tube 10, a winding membrane element 12 arranged inside the pressure tube 10 and one each pressure-tight in the open ends of the pressure tube 10
  • the pressure tube 10 contains a thin-walled sleeve 16 made of glass fiber reinforced plastic, the ends of which are reinforced by an insert 18.
  • the insert 18 is expediently a precision turned part made of plastic or metal, which has all the precautions, such as internal threads or internal grooves, for a reliable connection to the connecting body (14).
  • the two inserts 18 are first slid onto a cylindrical winding mandrel (not shown) and fixed to it at a distance from one another corresponding to the length of the pressure tube 10.
  • the mandrel diameter corresponds to the inside width of the pressure pipe 10 to be produced.
  • a winding is then placed on the rotating mandrel a curable synthetic resin impregnated glass fiber strand wound up in multiple layers in a close-lying spiral, so that a closed envelope 16 is formed.
  • the glass fiber strand is also wound onto the inserts 18 rotated with the winding mandrel, so that there is a positive and adhesive surface connection between the sheath 16 and inserts 18.
  • a chemical bonding agent can also be applied to the outer surface of the inserts before winding up the glass fiber strand.
  • a tube 10 consisting of several glass fiber layers is gradually created, which can be removed from the mandrel together with the now integrated insert parts 18 after the synthetic resin has hardened.
  • differently designed inserts 18 can be integrated in the pressure pipe ends without changing the manufacturing process or the tools to be used (FIGS. 1 to 4).
  • FIGS. 1 and 2 are relatively elongated insert ropes 18 with an internal thread 20, which are intended for receiving connecting bodies 14 provided with a corresponding external thread 22.
  • the pressure pipes according to FIGS. 3 and 4 are equipped with relatively short inserts 18 which are convexly curved on the outer surface and which have an inner groove 24 for receiving a snap ring 26 for the form-fitting holding of the connecting body 14 in the pressure pipe end.
  • the inserts 18 have a tapering rear end 30 in all exemplary embodiments, which ends on the outer surface of the inserts via a concavely curved region 32 into a larger convex Section 34 merges.
  • connection body 14 is sealed off from the pressure pipe 10, for example, by means of sealing rings 36, 38 acting axially (FIG. 2) or radially (FIG. 3).
  • the connection bodies are equipped with one (FIG. 3) or with two (FIGS. 2 and 4) bores 40, 42, 44 or line bushings for the connection of liquid lines.
  • the bore 40 'for the line connection is guided radially through the insert 18 and the plastic sleeve 16, while the connection body 14 as such has no bore or bushing.
  • the inlet end of a membrane module is shown with only one connection 40, 40 'for the raw water supply, while in FIGS. 2 and 4 the outlet end of the membrane module is shown with a central permeate connection 44 and an eccentric concentrate connection 42 .
  • the raw water connection 40, 40 'on one side and the concentrate connection 42 on the other side are each connected to an annular chamber 46 arranged between the connection body 18 and the membrane element 12, while the permeate connection 44 on the outlet side via the connection piece 48 with the permeate collecting tube of the membrane element communicates.
  • the stub 48 of the permeate collecting tube projecting on both sides is overlapped in a pressure-tight manner by an adapter piece 50 which, in the exemplary embodiments shown, is an integral part of the connecting body 18.
  • the adapter pieces 50 thus form a stable holder for the membrane element 12 and ensure its centered alignment within the pressure tube 10.
  • the adapter piece 50 additionally has the function of a closure cap for the permeate collecting tube which is open on both sides, while on the outlet side the adapter piece 50 provides a connection between Permeate collecting pipe and permeate connection 44 are made.
