AI Technical Summary
⚠Technical Problem
The existing 316L stainless steel acid leaching reactor is prone to leakage after long-term use, posing a safety hazard. It also has a short service life and cannot effectively handle the acid addition reaction of the slurry.
⚗Method used
A double-layer protective structure, consisting of a first acid-resistant mud layer, a fiberglass layer, and an acid-resistant brick layer, is installed inside the reactor to enhance the reactor's acid resistance. Combined with an automatic drain valve and stirring rod design, this ensures safety and durability.
🎯Benefits of technology
This extended the service life of the reactor to one and a half years, prevented leakage, improved production efficiency, and reduced safety risks.
