一种阳极氧化过程废酸的回用装置
摘要：
本实用新型涉及一种阳极氧化过程废酸的回用装置，属于膜技术领域。该阳极氧化过程废酸的回用装置，包括：降温槽，用于对废酸降温；预过滤器，连接于降温槽，用于对废酸进行预过滤去除大颗粒杂质；陶瓷纳滤膜，连接于预过滤器，用于对预过滤器的滤液进行分离，截留其中的Al3+；回收酸收集槽，连接于陶瓷纳滤膜，用于存储陶瓷纳滤膜的渗透侧得到的回收酸。能提高阳极氧化工艺过程中的酸使用效率，减少阳极氧化工艺中的废酸排放。
摘要（英）：

The utility model relates to a retrieval and utilization device of anodic oxidation process spent acid belongs to membrane technical field. This retrieval and utilization device of anodic oxidation process spent acid includes: cooling tank for cool down to the spent acid, prefilter connects in cooling tank for carry out the prefiltering to the spent acid and get rid of large granule impurity, thefilter membrane is received to the pottery, connects in prefilter for filtrating to prefilter is separated, holds back al3+ wherein, the recovered acid collecting vat is connected and is received thefilter membrane in the pottery for the recovered acid that the ceramic infiltration side of receiving the filter membrane of storage obtained. Can improve the sour availability factor among the anodicoxidation process, the spent acid that reduces in the anodic oxidation technology discharges.
