System and method for recovering organic waste gas by fluidized bed

The invention discloses a system and a method for recovering organic waste gas by a fluidized bed. The system comprises a waste gas induced draft fan, a fluidization adsorption device, a desorption device, a heating device, a condensation device and a cooling storage device. The waste gas induced draft fan is used for conveying waste gas into the fluidization adsorption device; the fluidization adsorption device is used for adsorbing volatile organic pollutants in the pollution gas and enriching the volatile organic pollutants in an adsorption material, and discharging the adsorption materialwith saturated adsorption to the desorption device; the heating device is used for heating the desorption device, so that the volatile organic compounds are volatilized and discharged into the condensation device; the condensation device is used for condensing and recovering the volatile organic compounds and sending completely condensed gas into the cooling storage device; and the cooling storagedevice is used for collec
