The invention discloses a fluidizing-catalyzing transfer method of making dimethyl ether out of methanol through fume heat exchange. The method comprises the steps as follows: raw material of methanol, regenerated catalyst which is cooled, and pre-lifted medium are fed into a fluidizing bed reactor for reacting under the conditions that the temperature is 150 to 500 DEG C, the pressure is 0.1 to 1.0 MPa, the liquid hourly space velocity is 0.5 to 4 hour<-1> and the weight ratio between the catalyst and the raw material is 1 to 20; the heat is removed from the circular fluidized bed reactor during the reaction process, and the reacting material and the coking catalyst are separated, wherein, the reacting material is separated to acquire the target product dimethyl ether. The coking catalyst after steam stripping is mixed directly with the regenerated fume to conduct heat exchange and coke burning regeneration. After indirect heat exchange, the regenerated catalyst and the coking catalyst are used circularly. By arranging a mixer and an optional heat exchanger for the high-temperature regenerated fume, the random regenerated catalyst and the low-temperature coking catalyst, the invention allows flexibly controlling to the temperature of the regenerated catalyst entering the reaction and the temperature of the coking catalyst entering the regenerator.
