AI Technical Summary

Technical Problem

In the existing trichlorosilane production process, hydrogen bubbles generated when metallic sodium and trichlorosilane are mixed in a solvent form foam, which reduces the effective volume of the reactor, makes stirring difficult and reduces efficiency, and causes material entrainment and loss.

Method used

A stirrer for trichlorosilane production is used, which drives the stirring paddle through a geared motor, detects the bubble height by combining an RF admittance switch and controls the lifting stroke of the cylinder, adjusts the position of the defoaming and dispersing disc, and uses strong shear force to quickly break up the bubbles, thereby improving the mixing efficiency.

Benefits of technology

It effectively breaks up air bubbles, improves production efficiency, ensures product quality, prevents material entrainment and loss, and enhances the operational stability and safety of the mixer.
