Abstract

The invention relates to a filter module having a module housing and at least one filter element. The filter module has at least one inlet opening, at least one filtrate outlet and a module housing at least one joint line.

What is claimed is:  
     
         1 . A filter module, comprising a module housing ( 2 ) and at least one filter element ( 1 . 1 ); 
 with the module housing ( 2 ) comprising a basic body ( 2 . 2 ) with at least one filtrate discharge ( 2 . 2 . 1   2 . 2 . 2 ) and two face sides ( 2 . 1 );    with at least one filter element ( 1 . 1 ) being disposed in the module housing ( 2 ), characterized in that the basic body ( 2 . 2 ) of the module housing ( 2 ) is arranged in several parts, with the individual parts being mounted to each other so that at least one partial joint is formed.    
     
     
         2 . A filter module as claimed in  claim 1 , characterized in that the at least one filter element is arranged as a tube membrane which is disposed between the two face sides ( 2 . 1 ) of the module housing ( 2 ).  
     
     
         3 . A filter module as claimed in one of the claims  1  or  2 , characterized in that the partial joint is arranged as a radial joint.  
     
     
         4 . A filter module as claimed in  claim 3 , characterized in that the parts of the basic body ( 2 . 2 ) are mutually connected by means of a radial flange ( 11 ).  
     
     
         5 . A filter module as claimed in  claim 4 , characterized in that the inner space of the module housing ( 2 ) is sealed from the ambient environment at the flanged connection ( 11 ).  
     
     
         6 . A filter module as claimed in one of the claims  4  or  5 , characterized in that the parts of the basic body ( 2 . 2 ) are connected to the radial flange ( 11 ) by means of a screwed connection.  
     
     
         7 . A filter module as claimed in one of the  claims 1  to  6 , characterized in that top plates ( 3 ) are arranged at the axial ends of the filter module.  
     
     
         8 . A filter module as claimed in  claim 7 , characterized in that the top plates ( 3 ) are connected with the module housing ( 2 ) in a leak-proof or gas-tight manner  
     
     
         9 . A filter module as claimed in one of the  claims 7  to  8 , characterized in that the top plates ( 3 ) are fastened to the module housing ( 2 ) by means of a screwed connection.  
     
     
         10 . A filter module as claimed in one of the  claims 1  to  8 , characterized in that the medium-conducting surfaces of the module housing ( 2 ) are coated.  
     
     
         11 . A filter module as claimed in  claim 10 , characterized in that the coating comprises one or several of the materials of chloropolyvinyl chloride (CPVC), polypropylene, polyvinylidene fluoride (PVDF), Hastelloy or titanium.  
     
     
         12 . A filter module as claimed in one of the  claims 1  to  11 , characterized in that the medium-conducting surface of the module is polished.  
     
     
         13 . A filter module as claimed in one of the  claims 1  to  12 , characterized in that the medium-conducting surface of the module housing ( 2 ) is plated preferably with platinum.  
     
     
         14 . A filter module as claimed in one of the  claims 1  to  13 , characterized in that at least one filter element ( 1 . 1 ) is arranged in an axially symmetrical manner in the module housing ( 2 ).  
     
     
         15 . A filter module as claimed in one of the  claims 1  to  14 , characterized in that the at least one filter element ( 1 . 1 ) is sealed off at its ends against the module housing ( 2 ) or the top plate ( 3 ).  
     
     
         16 . A method for applying a coating onto the surfaces of the module housing ( 2 ) of a filter module as claimed in one of the  claims 2  to  15 , characterized in that 
 at first the components of the filter module housing ( 2 ), comprising at least two-part basic body ( 2 . 2 ) and two face sides ( 2 . 1 ) with bores for guiding through the filter elements ( 1 . 1 , 1 . 2 , 1 . 3 ) arranged as a tube membrane are coated individually:  
 thereafter the components of the module housing ( 2 ), which means at least the parts of the basic body ( 2 . 2 ), are joined to each other:  
 thereafter the at least one filter element ( 1 . 1 , 1 . 2 , 1 . 3 ) is inserted into the module housing ( 2 ) in such a way that the at least one filter element projects on both sides beyond the face sides ( 2 . 1 ) of the module housing ( 2 );  
 thereafter the at least one filter element ( 1 . 1   1 . 2 , 1 . 3 ) is fixed by means of at least one top plate ( 3 ) to the face sides ( 2 . 1 ) of the module housing ( 2 ) and is sealed oft by means of sealing elements ( 4 ) against the inner space of the filter module housing ( 2 ).  
 
     
     
         17 . A method as claimed in  claim 16 , characterized in that the connection of the parts of parts of the basic body ( 2 . 2 ) of the module housing ( 2 ) occurs by means of a radial flanged joint ( 11 ).
