Waste acid recovery unit

In the process of steel pipe production, steel pipe manufacturers inevitably produce cleaning wastewater and waste acid due to process requirements. If the waste water and waste acid are directly discharged into the environment without treatment, it will cause serious environmental pollution and bad social impact; if traditional evaporation and concentration methods are used to treat waste acid or entrust a qualified third-party unit for recycling, Expenses remain high, increasing production and operating costs.

The waste acid recovery unit utilizes a new technology-frozen crystallization method to recover the waste acid produced in the production process of the enterprise. The freezing crystallization treatment of sulfuric acid pickling waste liquid is to separate the crystals of ferrous sulfate by controlling the crystallization conditions of ferrous sulfate from the waste liquid. To achieve the effect of purifying pickling waste liquid and recovering ferrous sulfate.
