Abstract

The invention discloses a microwave-coupled supergravity revolving bed device and application thereof. The device comprises a microwave generating device, wherein the microwave generating device can feed emitted microwaves inside a closed chamber consisting of an end cover and a shell body, and the microwaves act on reactants inside the closed chamber so as to heat the reactants and / or increase reaction rate. According to different feed-in modes, direct feed-in devices and indirect feed-in devices are present. According to the device disclosed by the invention, the rapid heating of the reactants is achieved by using the auto-heating effect of the microwaves to liquid while a supergravity revolving bed gives full play to the strengthening of mass transfer and mixing, so that the process temperature is guaranteed; and by using an electromagnetic effect of the microwaves, the reaction rate of a slow reaction process. The supergravity revolving bed can be filled with different types of fillers and can be applied to liquid-containing systems of different types such as liquid-liquid, gas-liquid, liquid-solid and gas-liquid-solid. The device has the advantages of small investment, low energy consumption, high heating speed and the like.
