The invention discloses a plate frame type thin film distillation assembly, a system and a distillation method, which are used for increasing the disturbance of to-be-distilled feed liquid in the plate frame type thin film distillation assembly and weakening the influence of temperature polarization and concentration polarization phenomena on the distillation speed. The plate frame type thin film distillation assembly comprises a plate frame (5), a functional thin film and turbulent flow rods (6). The plate frame (5) is provided with a feeding port plate (51), a discharging port plate (52) and two opposite side plates (53), wherein the feeding port plate (51) and the discharging port plate (52) are opposite, and the two opposite side plates (53) are located between the feeding port plate (51) and the discharging port plate (52). The functional film covers the top side and the bottom side of the plate frame (5), and an area enclosed by the functional film and the plate frame (5) forms a circulation channel of
