Distributor device for distributing liquid to tubes of a tube-bundle apparatus, and also tube-bundle apparatus, in particular falling-film evaporator

Abstract

A distributor device is provided for distributing liquid to tubes of a vertical tube-bundle apparatus that open out into an upper tube sheet. The distributor device includes a plurality of outlet openings that are directed downward. For improved liquid guidance, construction, and operation of the tube-bundle apparatus, the distributor device additionally includes laterally directed outlet openings. The tube-bundle apparatus includes a shell and a hood closing the shell at the top and a tube bundle arranged within the shell. The tube-bundle includes tubes opening out into an upper tube sheet and a distributor device arranged above the upper tube sheet, within the hood, for distributing liquid to the tubes.

 wherein the distributor device ( 114 ) additionally comprises laterally directed outlet openings ( 124 ) for the liquid ( 120 ).   
     
     
         2 . The distributor device ( 114 ) according to  claim 1 , wherein the laterally directed outlet openings ( 124 ) comprise a horizontal orientation. 
     
     
         3 . The distributor device ( 114 ) according to  claim 1 , wherein the distributor device ( 114 ) is constructed as a liquid collecting chamber, in particular as a cylindrical liquid collecting chamber, and/or as a bath distributor ( 122 ). 
     
     
         4 . The distributor device ( 114 ) according to  claim 1 , wherein the laterally directed outlet openings ( 124 ) are constructed as openings directly introduced into the distributor device ( 114 ), in particular as bore holes ( 126 ). 
     
     
         5 . The distributor device ( 114 ) according to  claim 1 , wherein, when liquid ( 120 ) is present within the distributor device ( 114 ), an adjacent wall, in particular the inside of a housing wall and/or of a hood ( 106 ) of a tube-bundle apparatus, is wettable with the liquid ( 120 ) via the laterally directed outlet openings ( 124 ). 
     
     
         6 . A tube-bundle apparatus ( 102 ) comprising a shell ( 104 ) and a hood ( 106 ) closing the shell ( 104 ) at the top, comprising a tube bundle ( 108 ) arranged within the shell ( 104 ), which tube bundle comprises tubes ( 112 ) opening out into an upper tube sheet ( 110 ) and comprising a distributor device ( 114 ) arranged above the upper tube sheet ( 110 ), in particular within the hood ( 106 ), for distributing liquid ( 120 ) to the tubes ( 112 ), which comprises a distributor device ( 114 ) according to any one of the preceding claims. 
     
     
         7 . The tube-bundle apparatus ( 102 ) according to  claim 6 , wherein, when liquid ( 120 ) is present within the distributor device ( 114 ), the inside of the hood ( 106 ) is wettable with the liquid ( 120 ) via the laterally directed outlet openings ( 124 ). 
     
     
         8 . The tube-bundle apparatus ( 102 ) according to  claim 6 , wherein the nominal diameter of the hood ( 106 ) corresponds to the nominal diameter of the shell ( 104 ). 
     
     
         9 . The tube-bundle apparatus ( 102 ) according to  claim 6 , wherein the tube bundle ( 108 ) extends up to the inside of the shell ( 104 ). 
     
     
         10 . The tube-bundle apparatus ( 102 ) according to  claim 6 , wherein the tube-bundle apparatus ( 102 ) is constructed as an evaporator, in particular as a falling-film evaporator ( 128 ).
