Animation demonstrates the working principles and characteristics of various tower equipment---sieve plate extraction tower.

Thread Content

The light phase (dispersed phase) is introduced at the bottom of the tower and dispersed through the sieve holes. It then rises in the heavy phase (continuous phase) and gathers at the bottom of the upper sieve plate to form a layer of light liquid, which is then dispersed and then aggregated. The process of dispersion is the extraction and mass transfer process. The extraction phase and raffinate phase are obtained at the top and bottom of the tower respectively. Performance characteristics: Sieve plate extraction towers are widely used in chemical production processes due to their large processing capacity, simple structure, and low cost. The flow structure of the liquid and liquid phases in the tower has an important influence on the mass transfer efficiency. At the same time, the flow structure of the continuous phase is closely related to the structure of the tower internals.
