Description

Technical Field

[0001] The utility model relates to the technical field of waste aluminum etching solution treatment, in particular to a filter for separating phosphoric acid and acetic acid. Background Art

[0002] Waste aluminum etching liquid is the waste liquid generated after wet etching of aluminum templates in the thin film transistor liquid crystal display industry. Its main components are phosphoric acid, nitric acid, and acetic acid mixture. The waste liquid composition is generally 50-60% phosphoric acid, 5-10% acetic acid, 3-5% nitric acid, and a small amount of heavy metal impurities (AL, Mo), etc. Generally, waste aluminum etching liquid is recycled and utilized by manufacturers with relevant qualifications, and phosphoric acid and acetic acid are extracted.

[0003] However, the recycled waste aluminum etching solution may contain some insoluble impurities. If the waste aluminum etching solution containing insoluble impurities is directly transported to the equipment for separating phosphoric acid and acetic acid, these insoluble impurities will accumulate together under long-term working conditions, which will easily cause the discharge pipe of the equipment for separating phosphoric acid and acetic acid to be blocked, and it is difficult to handle, thus affecting the treatment efficiency of the waste aluminum etching solution. Therefore, we propose a filter for separating phosphoric acid and acetic acid. Utility Model Content
