    Abstract: Provided are a device and a method for efficiently producing a polyester by using 1,4-butanediol as a starting material. The device for producing a polyester includes: a preparation tank (4) for starting material slurry; a storage tank (6) for starting material slurry; an esterification reactor (9); an initial polycondensation reactor (11); a middle polycondensation reactor (13); and a final polycondensation reactor (15). An exhaust system for each of the initial, middle, and final polycondensation reactors includes a wet condenser (17, 23, or 31) using a liquid containing 1,4-butanediol as a coolant; and a hot well (22, 30, or 38) connected to the corresponding wet condenser. Herein, process scattered substances scattering with exhaust are collected, and hydrolyzed in the hot well, so as to be returned to the esterification step. This allows the polyester to be efficiently produced.
