Problems solved by technology

[0005] First, in terms of strengthening the initial dispersion, the total amount of 24 tributary streams is very high, which produces a severe dilution effect on the main stream, which is very unfavorable for the rapid liquid-liquid reaction process
[0006] Second, in terms of intensified macroscopic mixing, the frequency of the 24 tributaries hitting the main flow cannot be determined due to the difficulty in grasping the rapid liquid-liquid reaction rate. In each impact cycle, there are three different times: mixing→reaction→intermittent During the reaction process, the reactant concentration fluctuates greatly, the reaction time and reactor space utilization rate are very low, resulting in a low coating rate
[0007] Third, in terms of strengthening the secondary rotation, since the flow section of the main channel is a regular rectangular flow channel of 1mm×5mm, the streamline of the secondary rotation is not good, and there is a dead angle in the mixture of strengthening mesoscopic and microscopic
[0008] In conclusion, the efficacy of the above two reactors in enhancing multiscale mixing still needs to be further enhanced

Abstract

The invention provides a supergravity-continuous micro impinging stream reactor based on the eight-trigram diagram principle. The supergravity-continuous micro impinging stream reactor comprises a main flow channel and 24 branch flow channel outlets corresponding to 24 branch flow channels; the main flow channel comprises 24 semicircular flow channels which butt joint sequentially and are arranged along the straight line direction and the radiuses of which are equal or change from small to large; the 24 branch flow channel outlets are respectively positioned in the inner sides of the 24 semicircular flow channels, and the circulation cross sections of the 24 branch flow channel outlets are circles with equal radiuses and the circle centers of the circles are coincided with the respective corresponding semicircular flow channels; the branch flow channel outlets and the corresponding semicircular flow channels are communicated via fan-shaped slits; the circle centers of the fan-shaped slits are coincided with the circle centers of the branch flow channel outlets; the widths of the fan-shaped slits are determined by guaranteeing that the initial velocity is greater than 1m / s when branch streams run into the main stream. According to the invention, the multi-scale mixing in the liquid-liquid reaction process can be intensified by utilizing the impinging of the high-frequency reversed supergravity field and a continuous ultrathin liquid membrane.

Description

technical field [0001] The invention relates to the technical field of chemical reaction engineering, in particular to a high-gravity-continuous micro-impingement flow reactor based on the Bagua diagram principle. Background technique [0002] Fuxi is the humanistic ancestor of the Chinese nation. "Taiping Yulan" once described that "Fuxi sits on the square altar, listens to the eight winds, and draws the eight trigrams." The Bagua diagram reveals two ways of rotating motion: the first one is to always rotate in one direction, which is called one rotation, and rotating equipment such as wheels, propellers, and motors are all one-time rotating equipment. The second is that when turning to 180 degrees on the basis of the first one, the rotation direction suddenly changes by 180 degrees, from clockwise to counterclockwise, or on the contrary, it is called secondary rotation, and secondary rotation equipment is very rare . In addition, the Bagua diagram also contains two small...
