Definitions

  • This invention relates to a filter module. More particularly, this invention relates to a filter module having a module housing, and at least one filter element. Even more particularly, this invention relates to a filter module having at least on inlet opening, at least one filtrate outlet and the module housing having at least one joint line.
  • Filter modules are known from process technology. They are used in many ways.
  • U.S. Pat. No. 4,368,119 shows an apparatus for filtering a liquid, for example.
  • U.S. Pat. No. 4,849,104 shows another apparatus filter module.
  • Especially filter modules which work according to the membrane separation method are used in the treatment of water, in desalination of sea water and briny water, in the foodstuff industry, in the pharmaceutical and electric industries to separate a component from a liquid or a gas.
  • Filter modules comprise a number of rod-like filter elements when configured according to the principle of tube modules which are arranged parallel with respect to each other. Groups of such filter elements are usually combined and clamped at the ends by means of tops in the module housing.
  • the tops extend perpendicular to the rods and are provided with a number of bores corresponding to the number of filter elements.
  • the internal space of the filter elements is sealed off at the ends with respect to the internal space of the module housing.
  • the medium to be filtered is introduced into the filter elements, the permeate passes through the membrane layer of the filter elements and the residue remains in the filter element or is discharged again via an outlet.
  • the invention is therefore based on the object of providing an embodiment of the filter module in which the application of a surface coating can occur in a simple manner and in a high-quality fashion. Furthermore, the invention is to provide a method in which the application or renewal of the surface coating occurs in a quick, cost-effective and high-quality way. This object is achieved by the features of the independent claims.
  • FIG. 1 shows a filter module in an embodiment with a radial flange
  • FIG. 2 shows a sectional view of the zone of a filter module at the end of the housing.
  • the filter module housing is configured in accordance with the invention with one or several partial joints, especially one or several partial radial joints.
  • a coating preferably one or several of the materials of chloropolyvinyl chloride (CPVC), polypropylene, polyvinylidene fluoride (PVDF), Hastelloy or titanium, no longer needs to be made through the small bores (according to the diameters of the filter elements) at the face sides of the module housing, but instead can simply occur through the considerably larger internal diameter of the module housing when the partial joint is opened.
  • This is especially advantageous when coating the internal face surfaces of the module housing, because the coating no longer occurs “around the corner” in this case, but in a virtually frontal fashion.
  • an arrangement with several radial flanges is appropriate, so that the surfaces to be coated are easy to reach and are not situated too far inwardly.
  • any other machining of the interior surfaces of the filter module such as polishing or plating (with platinum for example) is made much easier or even possible in the first place as compared with previously known methods.
  • the module housing parts are mutually connected in the zone of the flanges by means of a screwed connection and advantageously sealed off against the ambient environment with a sealing ring, for example.
  • the top plates can also be screwed onto the module housing and be sealed off.
  • the present invention provides a method for applying a coating onto the surface of the filter module housing.
  • the individual parts of the filter module housing are advantageously coated at first and then joined together. The precise procedure shall be explained below by reference to the enclosed drawings.
  • FIG. 1 shows a filter module in an embodiment with a radial flange
  • FIG. 2 shows a sectional view of the zone of a filter module at the end of the housing.
  • the filter module as shown in FIG. 1 has a number of filter elements 1 . 1 , 1 . 2 , 1 . 3 .
  • the rod-like filter elements have a cylindrical shape and a circular cross section, with each filter element being penetrated by a plurality of channels 1 . 1 . 1 .
  • the filter module further has a housing 2 in which the filter elements 1 . 1 , 1 . 2 , 1 . 3 are arranged in parallel.
  • the face sides 2 . 1 of the housing are provided with bores into which the filter elements 1 . 1 , 1 . 2 , 1 . 3 are fitted. At their ends the filter elements 1 . 1 , 1 . 2 , 1 .
  • the basic body 2 . 2 of the housing 2 is provided with a circular cross section and comprises the two filter outlets 2 . 2 . 1 , 2 . 2 . 2 and a conical connection piece 3 . 4 . each at its ends.
  • the so-called permeate passes through the membranes into the internal space of the housing 2 which encloses the filter elements 1 . 1 , 1 . 2 , 1 . 3 and exits through the filter outlets 2 . 2 . 1 and 2 . 2 . 2 (arrows 9 ).
  • the surface of the filter module housing 2 and the top 3 is coated, which is indicated here by the line 10 . Due to a radial partial joint which is arranged in this case in the form of a radial flange 11 , the entire surface 10 can be coated in accordance with the invention in a simple and high-quality fashion, which is not possible in an arrangement without a radial partial joint in particular for the internal surfaces 10 . 1 of the face sides 2 . 1 .
  • FIG. 2 shows a sectional view of the face-side area of the filter module housing.
  • the main parts 2 . 2 of the filter module housing 2 are coated at first along the line 10 which is shown in the dot-dash line.
  • the coating can preferably be made from the end which is opposite of the face side 2 . 1 through the opening with the interior diameter of the main part of the module housing 2 . 2 .
  • the coating of the zones 10 . 1 at the face side 2 . 1 of the module housing is also possible in a simple way and in a high-quality fashion.
  • CPVC chloropolyvinyl chloride
  • PVDF polyvinylidene fluoride
  • Hastelloy or titanium can be used as possible coating materials.
  • the main parts 2 . 2 of the filter module 2 are mounted on each other. In this embodiment the screwed connections of the flange 11 are tightened.
  • the filter elements 1 . 1 , 1 . 2 , 1 . 3 are inserted into the joined main parts 2 . 2 of the module housing 2 in such a way that their ends project at both sides beyond the face sides 2 . 1 of the module housing.
  • the sealing elements 4 and the top plates 3 are mounted at the face sides 2 . 1 of the module housing 2 . In this embodiment this occurs by means of a screwed connection.
  • This method can be used in accordance with the invention not only for the first mounting of the filter modules but is also preferably suitable for repairing damage to the coating surface, e.g. by wear and tear during operation.
  • a further advantage is the favorable possibility of inspecting the surface.
  • Advantages of the invention are further that also the cleaning of the module housing is facilitated and the exchange of individual main parts ( 2 . 2 ) of the filter module housing is possible in the case of damage.
