Abstract

The invention belongs to the technical field of devices for intensifying liquid and liquid quick micro mixing reaction, in particular relates to an impinging stream structure and an impinging stream and rotary material packed bed device, and solves the problem that the conventional impinging stream structure is not ideal and nonuniform in mixing effect. The impinging stream structure comprises a main feed pipe and a sleeve which are different in pipe diameter, wherein a plurality of main feed pipe discharge holes are formed in one side, near the sleeve, of the discharging section of the main feed pipe; the bottom of the sleeve corresponds to the discharging section of the main feed pipe; a plurality of sleeve discharge holes in one-one correspondence to the main feed pipe discharge holes in an up and down manner are coaxially formed in the bottom of the sleeve. According to the impinging stream and rotary material packed bed device, the impinging stream structure is arranged in a cavity of a rotor of the rotary material packed bed and is arranged in the axial direction of the rotor. the impinging stream structure and the impinging stream and rotary material packed bed have the advantages that fed feed in different amounts can be uniformly mixed, the reaction is quick, the reaction time is short, and the momentum loss is less, and are particularly suitable for quick reaction of batch feed feeding in different amounts in industry and the reaction system with the certain viscosity character.

Description

technical field [0001] The invention belongs to the technical field of enhanced liquid-liquid rapid microcosmic mixing reaction device, in particular to an impact flow structure and an impact flow-rotating packed bed device. Background technique [0002] Currently, impinging flow structures for liquid-liquid reactions are mainly submerged circulating impinging flow and impinging flow-rotating packed bed devices. However, there are still some deficiencies in the submerged circulating impingement flow. First of all, since the motor shaft on which the propeller is installed is a cantilever structure, if the shaft is longer or rotates faster, it is easy to cause vibration of the propeller and the motor shaft. Secondly, the motor shaft on which the propeller is installed needs to be installed with a shaft seal structure on the reactor wall, which increases the manufacturing cost of the reactor, and the shaft seal structure is easily damaged during long-term operation, which affe...
