AI Technical Summary

Technical Problem

In polysilicon production, compressor oil may have excessive acid value due to silane gas contamination, leading to bearing wear and equipment damage. Existing detection methods are outdated and cannot be adjusted in a timely manner, affecting production continuity and increasing maintenance costs.

Method used

An acid value detector and an acid neutralizer pump are integrated into the DCS control system to form an online adjustment system. Through oil-water separation and vacuum oil filtration, the acid value of the oil is detected and neutralized in real time, ensuring the timely circulation of lubricating oil.

Benefits of technology

It enables timely adjustment of the acid value of compressor lubricating oil, ensuring the stability of compressor operation, reducing equipment maintenance costs and oil consumption, and improving the degree of automation.
