FIELD: heat exchange equipment, in particular, film evaporators, applicable in rectifying plants of chemical and petrochemical industries. SUBSTANCE: in the known evaporator attached to the pipe connections with a diaphragm are caps with and lower distribution chambers are connected through a downflow pipe, located in the lower distribution chamber above the opening for the downflow pipe is a diaphragm with a pipe connection attached to it that is furnished with V-shaped cut-outs, the evaporator lower chamber is furnished with a level gauge. EFFECT: enhanced efficiency and reliability of operation within a wide range of loads concerning treated liquid and secondary vapor due to a more uniform distribution of treated liquid in heat-exchange pipes. 2 dwg
