AI Technical Summary
In the current production of vinyl acetate, polymerization inhibitors need to be added to prevent polymerization reactions, but existing mixing equipment requires large investments, consumes a lot of energy, and has high maintenance costs.
The mixing tube assembly, consisting of a Venturi mechanism, refining components, and helical blades, utilizes the Venturi effect and helical flow structure to achieve forced mixing of vinyl acetate and polymerization inhibitor, reducing mixing dead zones and improving dispersion and uniformity.
This method achieves efficient mixing of vinyl acetate and reagents without relying on large-scale mixing equipment, reducing equipment investment and energy consumption, and lowering production, storage, and transportation costs.
