The invention discloses a low-temperature plate type economizer, which belongs to the technical field of boiler flue gas recovery equipment and comprises two first connecting plates arranged in parallel, a second connecting plate and a third connecting plate are symmetrically and fixedly connected between the two first connecting plates, and a plurality of cooling plates are fixedly connected between the second connecting plate and the third connecting plate at equal intervals. A driving mechanism is arranged in the second connecting plate, the driving mechanism is in transmission connection with a cleaning mechanism, the cleaning mechanism comprises a cleaning plate in transmission connection with the driving mechanism, the cleaning plate is in sliding connection with the cooling plate, a circulating mechanism is arranged in the third connecting plate, and the circulating mechanism communicates with the cooling plate. By arranging the cooling plate, heat in flue gas is recycled, and meanwhile, the cleaning p
