Pipeline type gas-liquid two-phase flow mixer

Abstract

The invention relates to the technical field of gas-liquid mixing, in particular to a pipeline type gas-liquid two-phase flow mixer which is characterized in that a main body of the pipeline type gas-liquid two-phase flow mixer is of an annular column structure, two ends of the pipeline type gas-liquid two-phase flow mixer are provided with a water inlet connector and a water outlet connector, and an intercepting pore plate, a plurality of intercepting pore extension pipes, a plurality of impact cavities and a set of impact cavity supports are arranged in an internal cylindrical water passing channel. Water flow is accelerated through the intercepting pore extension pipes and then jetted into an impact cavity, strong convection is formed in the impact cavity, the gas-liquid contact time is prolonged, the gas-liquid mass transfer efficiency is improved, gas-liquid sufficient mixing can be achieved in a short-distance pipeline, and the gas-liquid two-phase flow pipeline mixing device is particularly suitable for the gas-liquid two-phase flow pipeline mixing situation with the small gas-liquid ratio, the limited space, the small pipe diameter and the low flow.

Description

technical field [0001] The invention relates to the technical field of gas-liquid mixing, in particular to a pipeline type gas-liquid two-phase flow mixer. Background technique [0002] Gas-liquid mixed mass transfer is a very important process requirement for chemical industry, environmental protection, medicine and other industrial fields. Convective contact towers such as packed towers and sieve tray towers are very effective gas-liquid mixing equipment. However, in some fields, such as medical injection, micro-reactors, small instruments, etc., due to the very small installation space, pipe diameter and water flow rate, it is impossible to use the above-mentioned large-scale equipment for gas-liquid mixing and dissolution. [0003] For the above situation, in the prior art, the way of pipeline static mixer or jet is mostly used for mixing and mass transfer. Due to the large difference in density between gas and liquid, when using a pipeline static mixer to achieve the ...

AI Technical Summary

Problems solved by technology

Due to the large difference in density between gas and liquid, when using a pipeline static mixer to achieve the ideal mixing effect, a very high flow rate is required, which makes the local resistance of the mixer huge; at the same time, due to the existence of a large number of micro-void structures, it is easy to cause blockage. It is clogged and difficult to clean; while the mixing effect of the jet is concentrated in the vortex area before and after the throat, the gas-liquid contact mixing time is too short, and the bubble size is large, so the mixing effect is not good
