ABSTRACT:
The invention relates to an apparatus for heat exchange between two liquids without solid matters contained in the liquids. The apparatus comprises a pressure vessel which is divided into a plurality of compartments, each compartment comprising an inner space having an open end and an outer annular space. A baffle having a closed upper end is provided around the upper portion of each inner space with an annular slit between the baffle and the wall of the inner space. The baffle extends to a level below the upper end of the inner space. Injection nozzles for the heat-receiving liquid are provided in the upper portion of the outer space of each compartment, and an outlet pipe is connected to the lower end of the outer space. Inlet and outlet pipes for the heat-delivering liquid are connected to the upper and lower ends respectively of the inner space. The inner and outer spaces respectively are connected in series, and the heat-delivering and heat-receiving liquids are fed in countercurrent with respect to each other. The heat-delivering liquid generates vapor that passes downwards through the annular slit between the inner space and the baffle and then upwards to meet droplets of the heat-receiving liquid from the nozzles.
