Device for cleaning a heat exchanger

Abstract

A heat transmitter, in particular a tube heat transmitter, for contaminated media such as, e.g., waste gas, having a gas entry opening and a gas exit opening with an entry opening for the tempering medium and an exit opening for the tempering medium as well as a cleaning device, wherein there is arranged in a circular gap of the heat transmitter, through which the contaminated waste gas passes, a rotatable cleaning spiral of the cleaning device, the external edge of which contacts at least in one section the external transmitter surface.

1 . A heat transmitter for contaminated media having:
 a gas entry opening and a gas exit opening with an entry opening for the tempering medium and an exit opening for a tempering medium and a cleaning device,   wherein the heat transmitter comprises:
 a rotatable cleaning spiral of the cleaning device, wherein:
 the rotatable cleaning spiral is arranged in a circular gap of the heat transmitter, the circular gap being configured for contaminated waste gas to pass therethrough; and 
 the external edge of the cleaning spiral contacts at least in one section an external transmitter surface. 
 
   
     
     
         2 . A heat transmitter according to  claim 1 , wherein an internal edge of the cleaning spiral contacts at least in one section an internal transmitter surface. 
     
     
         3 . A heat transmitter according to  claim 1 , wherein the cleaning spiral is motion-coupled with a drive, which is arranged at an external surface of the heat transmitter. 
     
     
         4 . A heat transmitter according to  claim 3 , wherein the cleaning spiral is connected via a drive shaft with the drive. 
     
     
         5 . A heat transmitter according to  claim 4 , wherein a through-passage of the drive shaft through a housing of the heat transmitter is hermetically sealing. 
     
     
         6 . A heat transmitter according to  claim 1 , wherein the cleaning spiral is made of a spiral-like coiled strip-like material. 
     
     
         7 . A heat transmitter according to  claim 6 , wherein the cleaning spiral is made of a material having high mechanical strength. 
     
     
         8 . A heat transmitter according to  claim 1 , wherein the cleaning spiral is provided at an internal edge and/or at an external edge thereof with a cleaning edge. 
     
     
         9 . A heat transmitter according to  claim 1 , wherein underneath the level of the cleaning spiral there is arranged a sump container for receiving contaminations. 
     
     
         10 . A heat transmitter according to  claim 1 , wherein underneath the level of the cleaning spiral there is provided a revision opening in a housing of the heat transmitter. 
     
     
         11 . A heat transmitter according to  claim 1 , wherein within the circular gap there is provided at least one distributor device for filling in a cleaning medium. 
     
     
         12 . A heat transmitter according to  claim 11 , wherein the distributor device is arranged between the gas entry opening and the gas exit opening.
