A multi-component layered symmetrical baffle impinging flow mixing reactor

Abstract

A multi-component layered symmetrical baffle-type impinging flow mixing reactor, which relates to a chemical reactor, wherein multiple sets of feed ports of the reactor are coaxially opposed, that is, the reactor is a plurality of sets of coaxially opposed feed materials The impact surface of each group of material inlets is provided with baffles perpendicular to the inlet and mutually symmetrical, and baffles are provided between each group of feeding pipes; when the invention works, the two nozzles of each group of feeding pipes eject The material undergoes an impingement flow reaction. The high turbulent impact in the axial direction at the initial stage of the reaction achieves preliminary mixing, and then it tends to move outward along both sides of the radial direction and leave the center to impinge on the flow field. At this time, the setting of the two symmetrical baffles prevents this deviation tendency, so that the fluid flows back to the high turbulence area to achieve sufficient reaction and mixing. And under the action of the baffle, the material forms a reciprocating flow, which greatly increases the residence time of the material in the impact area, thereby improving the working efficiency of the reactor, and the reactor is easy to install and is suitable for various working conditions , low maintenance costs.

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.
