Patent ID: 8206558

Claim:
A device for processing process or industrial wastewater comprising an evaporator ( 4 ) having a heating side, the evaporator ( 4 ) is operated by vapor, which is condensed on the heating side during operation, the evaporator comprising a separating device ( 8 ) and a tube bundle—heat exchanger ( 5 ) having a side for purified distillate connected to the separating device ( 8 ) for separating the distillate from a floating organic phase or free liquid components, the separating device ( 8 ) and the distillate side of the tube bundle—heat exchanger ( 5 ) located in the evaporator ( 4 ) are connected to each other without any deflections above an over flow ( 24 ) such that, in use, a liquid level in the separating device ( 8 ) and in the evaporator ( 4 ) merge with one another at the same height, the separating device ( 8 ) comprising a pressure relief valve ( 20 ) and a leveling device ( 12 ), in communication with the pressure relief valve ( 20 ), which opens the pressure relief valve ( 20 ) when the liquid falls below a set level and closes the pressure relief valve ( 20 ) when the liquid exceeds a set level.
