Title: Heat recuperator for processing plant - uses extra heat exchanger to transfer heat between discharge and return flows for dipping bath
Inventor: DIETRICH ROLF DIPL PHYS
IPC: F28D21/00
Filed: 1980-05-06
Abstract: The heat is recovered from the hot water discharged from the bath, in which the components are dipped and adds it to the return flow. The discharged hot water passes through a heat exchanger before passing through the usual cooling stage which precedes a desalination stage. After leaving this stage, the water which is now cool is passed through the heat exchanger, so as to receive heat from the water at its maximum temp. The return flow can then be passed through the usual heater for return to the bath. Due to the heat received from the heat exchanger, less heat is then required from the heater.
