Abstract

The invention provides an ultrasonic microwave coupling hypergravity reaction device and system. On the one hand, the dispersing and mixing effects of the whole device can be further improved, so thatthe reaction device has extremely high dispersing and mixing effects, and gas obtained after supergravity and microwave coupling exists in liquid in a micro-nano level bubble form; on the other hand,the purpose of uniform heating can be achieved for a heating system; meanwhile, an ultrasonic feed-in unit is arranged at the bottom of a second cavity, solid-liquid or gas-liquid dispersion can be enhanced, a supergravity unit and the microwave feed-in unit are also used, the dispersity of the gas in the liquid is good, and the gas bubbles reach the micro-nano level, so that the difficulty of liquid overflowing caused by ultrasonic mechanical vibration improved, the defect that the staying time of the gas in the liquid is short due to ultrasound is overcome, and the device is especially suitable for gas-liquid, gas-liquid-solid and other multi-phase reaction systems.

Description

technical field [0001] The invention relates to the technical field of reactors. More specifically, it relates to an ultrasonic microwave coupling hypergravity reaction device and system. Background technique [0002] Multiphase reactions widely exist in petrochemical, fine chemical, environmental chemical and biochemical industries, and the core of multiphase reactions is reactors, such as fluidized beds and reactors. In a multiphase reactor, mass transfer, mixing and heat transfer between phases are important indicators to determine the performance of the reactor, which directly affect the reaction intensity, conversion rate and product quality, especially for mass transfer, which is the overall reaction control step and involves liquid phase Or the reaction process of nanometer solid phase catalyst, in the reaction process, the gas-liquid contact area and the residence time of the gas phase in the liquid phase have an important influence on the reaction effect. However,...
