废酸再生处理及回收系统

　　Waste acid regeneration treatment equipment.
　　Principle: by adding sulfate crystallization distillation process, the waste acid ferrous chloride by sulfate crystallization separation, improve concentration, cooling, crystallization, separation, the mother liquor back to the system and extract the dilute acid and reuse.
　　Composition: Graphite evaporator, graphite condenser, preheater, graphite mold, crystal, liquid separator, cooling device.
　　Characteristic：
　　1, process control: the precise control of the amount of sulfuric acid, sulfuric acid will not be affected by the impact of acid pickling speed.
　　2, energy-saving aspects: liquor into the evaporator after two grade heat; the temperature of liquid to about 80 degrees, saving heat.

　　Technology advantage
　　（1） stable operation
　　（2） low operating cost
　　（3） reduction of sludge volume
　　（4） small area
　　（5） the treatment effect is good
　　（6） adjustable high
　　（7） fully automatic control
　　（8） long service life

　　Characteristic：
　　The equipment is suitable for a wide range, easy operation; large processing capacity, high cost （relative to the acid membrane recycling equipment）， according to the water quality, water requirements selection, adjustable high to avoid the waste of money. The equipment has a long service life, low maintenance rate; low energy consumption; regeneration at room temperature, the whole set of equipment can achieve zero emissions of acid recovery.
