Square venturi mixer with push-pull structure

Abstract

The invention discloses a square venturi mixer with a push-pull structure. The square venturi mixer comprises a mainstream fluid flow-in pipeline, a mainstream fluid shrinkage section, a mainstream fluid throat pipeline, a mainstream fluid diffusion section and a mainstream fluid flow-out pipeline which are communicated in sequence, as well as a side face fluid lead-in pipeline which is arranged at the upper end of the mainstream fluid throat pipeline and is communicated with the mainstream fluid throat pipeline, wherein the mainstream fluid flow-in pipeline, the mainstream fluid throat pipeline, a mainstream fluid flow-out pipeline and the fluid lead-in pipeline are square; the mainstream fluid shrinkage section and the mainstream fluid diffusion section are of quadrangular pyramid-like structures; all the mainstream fluid flow-in pipeline, the mainstream fluid shrinkage section, the mainstream fluid throat pipeline, the mainstream fluid diffusion section and the mainstream fluid flow-out pipeline comprise upper parts and lower parts; grooves are formed in the vertical wall surfaces of the upper parts and convex edges matched with the grooves in shape are formed in the vertical wall surfaces of the lower parts. The square venturi mixer with the push-pull structure is suitable for wide range flow rate proportioning of a mainstream fluid and lead-in fluid and is used for effectively improving the mixing efficiency of continuous phase liquid and diffusion phase liquid.

AI Technical Summary

Benefits of technology

This new type of valve called Ventedmixers (VIM) was developed by researchers over 20 years ago but they were limited because it had certain technical features such as high mixing efficacy or low pressure drop compared to traditional designs like those previously described. These improvements led them towards better performance in different applications where there may require more precise control over the mixture' characteristics during processing.

Problems solved by technology

This patented technical solution described by this patents describes various types of venturis that can improve their performance when mixed gases at different pressures. However, current devices have limitations such as requiring large sizes due to limited space available on both sides of these systems, difficulty controlling the volume of each component being mixed, difficulties in manufacturing precision parts, etc., making them difficult to use reliably over time without maintenance issues.
