Connecting piece of a transport line

Abstract

A tempered connecting piece is provided for transporting a viscous fluid, and includes an excess pressure release component, which separates the inside of the connecting piece from a discharge line and is fixed to an outer edge on the discharge line. The excess pressure release component is designed to release the discharge line in the event of predetermined excess pressure and a mixing element, which thoroughly mixes a fluid flow in the region of the excess pressure release component, is arranged in the inside of the connecting piece.

1 . A temperature-regulated connecting piece for transporting a viscous fluid, comprising: an excess pressure release component, which separates an interior of the connecting piece from a discharge line and is fixed with an outer edge to the discharge line the excess pressure release component is provided to free the discharge line in the presence of a preset excess pressure; and a mixing element is provided in the interior of the connecting piece; said mixing element thoroughly mixing a fluid flow in the region of the excess pressure release component. 
     
     
         2 . The connecting piece according to  claim 1 , characterised in that the excess pressure release component is set back from the interior of the connecting piece. 
     
     
         3 . The connecting piece according to  claim 1 , characterised in that the excess pressure release component is a bursting element, preferably a bursting disc, or an excess pressure valve. 
     
     
         4 . The connecting piece according to  claim 1 , characterised in that, in the presence of excess pressure, the excess pressure release component frees a large area, at least 70%, of its area facing the interior of the connecting piece. 
     
     
         5 . The connecting piece according to  claim 1 , characterised in that the connecting piece can be temperature-regulated by means of thermal insulation of the connecting piece and/or by means of heating or cooling elements. 
     
     
         6 . The connecting piece according to  claim 1 , characterised in that it comprises a bore for sampling fluid from the interior of the connecting piece before the excess pressure release component, preferably immediately before the excess pressure release component. 
     
     
         7 . The connecting piece according to  claim 1 , characterised in that it has a bore for accommodating a temperature and/or pressure sensor, preferably immediately before the bursting disc, wherein the bore is optionally suitable at the same time for sampling fluid from the interior of the connecting piece. 
     
     
         8 . The connecting piece according to  claim 6 , characterised in that the bore is a closable valve. 
     
     
         9 . The connecting piece according to  claim 1 , characterised in that the excess pressure release component is a bursting element, and a cutting element, preferably a bursting spike or a blade, is positioned in the discharge line in such a way that, in the presence of excess pressure in the connecting piece, the bursting element is pressed against the cutting element and thus bursts open. 
     
     
         10 . The connecting piece according to  claim 1 , characterised in that the excess pressure release component is a bursting element which is curved centrally, preferably curved convex or concave in the direction of the interior of the connecting piece. 
     
     
         11 . The connecting piece according to  claim 1 , characterised in that at least one heat carrier channel is provided in the region of the excess pressure release component. 
     
     
         12 . The connecting piece according to  claim 1 , characterised in that the excess pressure release component is clamped, preferably flange-mounted, in a holding fixture in the inner wall of the discharge line. 
     
     
         13 . A method for transporting a viscous fluid through a heat exchanger line, which includes a connecting piece according to  claim 1 . 
     
     
         14 . The method according to  claim 13 , characterised in that the viscous fluid is thermally unstable. 
     
     
         15 . The method according to  claim 13 , characterised in that the viscous fluid is a cellulose solution.
