Abstract:

The vane separation element is a kind of element which mainly relies on inertia to separate gas and liquid. It is widely used in the field of gas and liquid separation because of its characteristics of high throughput, high separation efficiency and low pressure drop. In this paper, the separation mechanism, structure and performance factors of the blade separation element were investigated in detail. The research progress of the separation mechanism such as droplet inertia separation, droplet impact and secondary entrainment caused by liquid film rupture in the vane flow path was discussed. The main structural characteristics of the vane-type gas-liquid separation element were summarized, and the specific effects of structural parameters such as curvature number, bending angle, spacing and hydrophobic hook on the separation performance were analyzed. By comparing the advantages and disadvantages of different existing vane structures and their application situations, the optimization direction of increasing the interception area and opening up the drainage channel of vane structures was put forward. The application status of wave-plate separation element and static rotation element was analyzed, which provides reference for application selection and optimization of vane gas-liquid separation technology. The internal effects of air velocity, pressure and inlet humidity on the performance of the corrugated plate-vane separation element were summarized. Finally, combining the separation mechanism, structure research and performance influence law, the structural design and performance optimization direction of the wave-plate separation element were summarized and prospected.

Key words: vane type separation element, separation mechanism, performance optimization, structural research
