Waste Hydrochloric Acid Recycling Station
        To respond the national requisition requisition for environmental protection, while developing production, Our company investe a huge sum of money in founding the sour regeneration station which is to deal with the abolished acid of the pickle production line. Not only can this action benefit the people and protects the environment but also can make the wastes be utilized again, reduce loss, and economize national resources.
1:The recycling of abolished acid can protect the environment.
        There is a large amount of Fe2O3 and other impurity in abolished sour liquid discharged by pickling unit, it would make great pollution to the environment, if it was not recycled and entered sewer and then flowed into rivers.(1)Abolished sour liquid corrodes sewer especially the metal pipeline. (2)Enter water, it can  cause fish death, and make people and domestic animals which drink this water poison until die, etc.
2:The recycling and treating of abolished acid can regenerate acid and can be used for pickling again.
        The recycling and treating of abolished acid can greatly reduce the acid consume. Without recycling, the acid consume will be up to about 18 kilogram for each ton steel contrasting with about only 4 kilograms with having recycling.
3:Have offered the important prerequisite for improving the production capacity of pickling unit.
        The device of recycling and treating of abolished acid provides enough acid for pickling strip, which establishes the reliable material base for good quality and high output.
4:The worth secondary produces can be generated during recycling process.
        The roasting of waste liquid of pickling will generates the by product iron oxide. It is the raw materials in manufacture of magnet material and pigment, and can be used to make deoxidized iron powder in metallurgy factory or to carry on iron-smelting again in sintering plant.

  • Density of recycled hydrochloric acid :190-210g/I
  • Secondary product,  Fe2O3≥99.3%, annual output 3,000 tons.
