AI Technical Summary

Technical Problem

After the single crystal furnace has been running for a long time, the volatiles in the filter canister have not been completely burned, which has led to damage to the filter bag, increased equipment maintenance costs, and the risk of explosion. At the same time, oxides have entered the vacuum pump chamber, causing the pump to overheat or jam, affecting production.

Method used

A rapid stirring oxidation reaction device for volatiles in a filter can is designed. By setting stirring blades and a secondary oxidation mechanism inside the filter can, the stirring blades are rotated using a servo motor and a cylinder. Combined with the oxygen supply from the secondary oxidation mechanism, the volatiles are fully combusted, preventing damage to the filter bag and oxides from entering the vacuum pump.

Benefits of technology

It achieves complete combustion of volatiles, avoids damage to filter bags and vacuum pumps, improves production safety and equipment lifespan, and reduces maintenance costs.
