Heat exchanger and method for demisting

Abstract

The heat exchanger includes a case with at least a case inlet and at least a case outlet. A separation structure located within the case defines a first section and a second section. A bundle of tubes or other means for transferring heat is housed within the first section. The first section has the case inlet and the second section has the case outlet and a liquid drainage. The heat exchanger also has channels having longitudinal axes directed towards a side of the case.

1 . A heat exchanger comprising a case with at least a case inlet and at least a case outlet, a separation structure located within the case defining a first section and a second section, a bundle of tubes or other means for heat transfer housed within the first section, wherein the first section has the case inlet and the second section has the case outlet and liquid drainage, and at least a channel having a longitudinal axis directed towards a side of the case. 
     
     
         2 . The heat exchanger of  claim 1 , further comprising two channels having longitudinal axes directed towards opposite sides of the case. 
     
     
         3 . The heat exchanger of  claim 1 , wherein the separation structure includes at least a wall extending from the top of the case and at least a diverter at the bottom of the case, the at least a diverter defining the at least a channel. 
     
     
         4 . The heat exchanger of  claim 3 , wherein the diverter has a wedge shape. 
     
     
         5 . The heat exchanger of  claim 1 , wherein the case outlet is provided at the top of the case and is adjacent the separation structure. 
     
     
         6 . The heat exchanger of  claim 1 , wherein the liquid drainage is provided at the bottom of the case and is adjacent the separation structure. 
     
     
         7 . The heat exchanger of  claim 1 , further comprising a second liquid drainage at the first sector. 
     
     
         8 . The heat exchanger of  claim 7 , wherein the second liquid drainage is provided at the bottom of the case and is adjacent the separation structure. 
     
     
         9 . The heat exchanger of  claim 1 , wherein the at least a channel has substantially constant cross section. 
     
     
         10 . The heat exchanger of  claim 1 , wherein the longitudinal axis of the at least a channel defines an angle between 5-35 degree with the side of the case. 
     
     
         11 . A method for demisting a gas passing through a heat exchanger,
 the heat exchanger including a case with at least a case inlet and at least a case outlet, a separation structure located within the case defining a first section and a second section, a bundle of tubes or other means for heat transfer housed within the first section, wherein the first section has the case inlet and the second section has the case outlet and a liquid drainage, the heat exchanger including at least a channel for directing a gas passing from the first section into the second section, wherein the heat exchanger has at least a channel having a longitudinal axis directed towards a side of the case, the method comprising directing through the at least a channel the gas passing from the first section into the second section towards the side of the case.
