Introduction
A special pickling acid regeneration system is the natural completion to a full hot dip galvanizing plant. Thanks to the use of regeneration systems we can positively impact the environment while elevating the production performance in the plant.
Great savings in disposal costs are the main advantage of installing an acid regeneration system in the plant. Any modern hot dip galvanizing installation should include this specific system, which saves money and improves surface quality. In addition, the great reduction in environmental impact can help the galvanizer in gaining important credits for specific public or private tenders where sustainability is a plus.
Principle:
by sulfate crystallization and distillation process, the ferrous chloride in waste acid will be separated through sulfuric acid crystallization, increasing concentration, cooling, crystallization, separation. Then the mother liquid is back to the system, and the dilute acid which are extracted can be reused.
Composition:
- Graphite evaporator,
- graphite condenser,
- preheater,
- graphite crystallizer,
- crystal - liquid separator,
- cooling device.
Characteristic:
1, process control: precisely control the amount of sulfuric acid, will not cause excessive sulfuric acid to affect the pickling speed .
2, energy-saving: after two-stage heat exchange before the mother liquid enters the evaporator, the temperature of mother liquid reaches about 80 degrees, saving heat.
Technology advantage
(1) stable operation
(2) low operating cost
(3) reduction of sludge volume
(4) cover a small area
(5) good processing effect
(6) good adjustability
(7) fully automatic control
(8) long service life
Characteristic:
- The equipment is suitable for a wide range, easy operation;
- large processing capacity, cost-effctive.
- Customer can choose the model according to the requirement of water quality and water volume.
- Because of good adjustability, it can avoid wasting money.
- The equipment is with a longer service life, low maintenance rate;
- wasted acid regeneration is processed at room temperature, lower energy consumption;
- the complete set of waste acid regeneration equipment can achieve zero emission.
