The invention provides a microwave coupling supergravity reaction system for continuous production of porous materials. According to the microwave coupling supergravity reaction system, a supergravityreactor, a microwave feeder, a first high-shear pump, a second high-shear pump and a filter are arranged, supergravity technology and high-shear technology are combined, and by means of shear force and centrifugal force of the high-shear pumps, materials meet the homogenizing process requirements under the action of high-speed shearing and friction extrusion; with the help of the rapid microscopic premixing characteristic of the supergravity reactor, the nucleation process is carried out in a microscopic uniform environment; the premixing and reaction temperature is accurately controlled through heating by means of microwave technology, and further the microwave coupling supergravity reaction system capable of realizing continuous production is formed through cooperation of the above instruments, the mass transfer rate and the heat transfer rate are accurately controlled, and the problems of large production particles and non-uniform particle size distribution caused by non-uniform mixing and non-uniform reaction temperature of porous materials are solved; the premixing stage and the crystallization stage are carried out in a same reactor, so that the occupied area of equipment issaved, and the operation process is simplified.
