AI Technical Summary

Technical Problem

Existing gas distributors, when used in large-diameter applications, require a large distribution space and a large number of distribution plates, making them inconvenient to use. Furthermore, they lack a specific design for the relationship between gas flow rate and distributor size, which affects the uniformity of gas distribution and reaction results.

Method used

Based on the reaction process information, design conditions are determined, distributor type is selected, and the size design of gas distributor is quantified through computational fluid dynamics simulation and experimental verification to ensure gas uniformity. Pipe-type or distribution disc type distributors are used, and the effective pressure drop ratio is calculated to judge gas uniformity. The relationship between pressure difference and orifice diameter is fitted.

Benefits of technology

The uniformity of the gas distributor was achieved through quantitative design, ensuring uniform gas distribution in the liquid and improving reaction efficiency and effectiveness.
