Detailed Product Description: | A large amount of an acidic solution of metal surface treatment process. When the acid in the metal reaches a certain concentration, the treatment effect due to reach the technical requirements, the acid needs to be reconstituted and replacement. In this process, a large amount of waste acid is produced. These waste acid because it contains a higher concentration of the acid and metal ions, causing a threat to the environment, the need for treatment, recycling waste acid lotion main methods: heating evaporation method, specialty resins exchange and diffusion dialysis membrane three. Heating evaporation method with high energy prices have gone up, and the economic cost has been inconsistent, with technological development, the resin exchange and diffusion dialysis membrane technology molding. Diffusion dialysis method has been commercialized in Germany, into a few years, some domestic manufacturers in a small amount of pre-production, the device maximum processing capacity of 5M3 / d, due to the small amount of processing, short membrane life, easy to aging damage, excessive cost and other reasons, to limit industrial production use. ? Resin exchange method is to wash through the purification of waste acid recovery equipment, filler block acid ions are adsorbed metal ions penetrate with liquid filler layer, acid and metal impurity separation, with the same amount of water flushed through the liquid on the packing acid radical so as to obtain substantially equal to the concentration of the spent acid wash acid regeneration, the acid liquid can be re-configured to use. Flowthrough recycled according to the nature of impurities. I. Features: 1. Hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid, hydrofluoric acid and mixed acid are effective purified recycled. 2 purified and high acid concentration, recycling to reduce production costs. 3 acid, metal salts separated from metal conducive to recycling. 4 After purification of waste acid lotion treatment recovery equipment, to achieve zero discharge of wastewater. 5 clean production, energy conservation, environmental protection equipment. 6 full automation, fine for simple, save on labor costs. Second, the technical parameters: 1 single equipment capacity 5-30M3 / d. 2 acid recovery was more than 85-95% 3 working voltage 380V, 50HZ three, in particular: 1. Packing is the core technology of purification recycling equipment, according to the enterprise needs to be explored experimental waste acid lotion, small scale, choose the best separation Purification of filler. 2 conducted a pilot to determine the recovery and purification of process parameters, determine the product parameters according to the test data, design and manufacturing. 3 if the company intends to implement zero discharge of wastewater, the need to increase other processing equipment. |
