FALLING FILM TYPE HEAT EXCHANGER

WIPO Patent Application WO/2018/189887

A1

[Problem] To provide a falling film type heat exchanger that can not only cool a high temperature fluid within a very short time while having a simple structure but also allows parts on which cooled fluid has adhered to be cleaned easily and reliably. [Solution] Provided is a falling film type heat exchanger 1 that comprises a cylindrical rectifier 12 with a bottom wherein the upper portion thereof is open to the atmosphere, a plurality of orifices 14 formed into a loop on a horizontal flat face of the rectifier 12 bottom, a heat transfer medium distribution pipe 31 hanging from the rectifier 12, and a heat exchanger 21 housing the heat transfer medium distribution pipe 31, and that causes the fluid for heat exchange dripping from the orifices 14 in a distributed manner to flow down and be distributed as a liquid film along the outer surface of the heat transfer medium distribution pipe 31 and performs crossflow, bulkhead-type heat exchange with the heat transfer medium flowing in the heat transfer medium distribution pipe 31, wherein the orifices are provided with funnel-shaped tapers.
