Description

technical field [0001] The invention relates to a gravity rotating packed bed and its application, in particular to an ultrasonic coupling supergravity rotating packed bed and its application, belonging to the field of supergravity technology. Background technique [0002] High-gravity technology is considered to be a breakthrough technology that strengthens the reaction separation process limited by transfer and mixing. It is known as the "transistor of the chemical industry" and "a cross-century technology". Significance. Its core equipment is a rotating packed bed, which is a new type of equipment developed in the 1980s. It uses the centrifugal force generated by the rotation to simulate a hypergravity environment to strengthen the transfer and mixing process, which can greatly improve the efficiency of the transfer and mixing restrictions. The efficiency of the reaction and separation process significantly reduces the volume of the reaction and separation device. Early...
