 | Replacement of activated carbon ① vacuum gauge; ② three-way ball valve; (3) feeding port; (4) discharge port;
Specific replacement process:
1. Close the two butterfly valves on the solvent column (butterfly valve ② and butterfly valve ③ in 10.2);
2. Check whether ① (vacuum gauge) is under normal pressure. If it is under vacuum state, supplement air to normal pressure through ② (three-way ball valve)
3. Open ③ (feeding port) and ④ (discharging port);
4. Activated carbon flows out from ④ (discharge port); Tighten the clamp after cleaning;
5. Pour clean and dry activated carbon from ③ (feeding port); After installation, tighten the clamp;
6. Through the operation of ② (three-way ball valve), vacuum the solvent column and replenish air for three times.
7. Repeat 5.11.2 to flow the circulating gas through the solvent column. |
Electrical specification | AC220V 6KW*2 |
Preparation and inspection before use | 1. Prepare sufficient high purity working gas (please refer to Table 1 for gas specifications)

Operation precautions | 1. Personnel shall not use the glove box without training;
2. Prohibit the use of materials that can poison the regeneration catalyst, such as: sulfhydryl compounds, etc.
3. Do not use volatile solvents that will damage plexiglass, such as acetone, without permission;
4. Before using volatile solvent, contact the person in charge to unload the water probe;
5. Open the activated carbon circulation system when using volatile solvent;
6. When using the glove box, do not have long nails, do not wear sharp objects (such as watches, jewelry, etc.); |
