Impinging stream mixing reactor with multiple groups of layered symmetric baffles

Abstract

The invention discloses an impinging stream mixing reactor with multiple groups of layered symmetric baffles, and relates to a chemical reactor. Multiple groups of material inlets of the reactor are coaxially and oppositely arranged, namely the reactor consists of multiple groups of coaxially and oppositely arranged material feeding pipes; mutually symmetric baffles perpendicular to each group of material inlets are arranged on the impinging surfaces of the material inlets; baffle plates are arranged between the material feeding pipes in each group. When the impinging stream mixing reactor works, two nozzles of each group of material feeding pipes jet materials to carry out impinging stream reaction; in the initial reaction stage, preliminary mixing is realized through axial high-turbulence dynamic impinging, and then a trend that the impinging stream outwards moves along two sides of the radial direction and leaves a central impinging stream field is generated; at the moment, by the arrangement of two symmetric baffles, the deviation trend is blocked, so that fluid flows back into a high-turbulence dynamic region to realize full reaction and mixing; furthermore, under the action of the baffle plates, the materials form cyclically reciprocating streaming, so that the retention time of the materials in an impinging region is greatly prolonged, and the working efficiency of the reactor is improved; meanwhile, the reactor is convenient to install, applicable to multiple working conditions and low in maintenance cost.

Description

technical field [0001] The invention relates to a chemical reactor, in particular to a symmetrical baffle plate impinging flow mixing reactor with multi-component layers. Background technique [0002] Impinging flow is a relatively novel technical method, which was first proposed by Elperin. Its basic idea is that two or more streams of homogeneous or heterogeneous fluids move towards each other and collide to generate a high turbulence area, which provides a good environment for strengthening heat and mass transfer. Excellent condition. The continuous phases of the two fluids collide with each other, reciprocating and oscillating, resulting in intense mixing in the impact zone, resulting in homogenization of temperature and composition. This is beneficial to increase the average push force and facilitate the transfer process. Due to its special flow structure of impinging on each other, there are wide-spectrum multi-frequency pressure fluctuations in the subsonic range in...

Problems solved by technology

[0003] At present, most impingement flow reactors used in industry are guide tubes with built-in propellers. Although the mixing efficiency has been improved, the propellers are expensive to manufacture and easy to wear

However, the impingement flow reactor formed by the jet has a small impact area and limited effective mixing capacity, which greatly limits the application of impingement flow technology in industrial production.
