Description
Technical field
The utility model relates to field of metallurgy, particularly, relates to a kind of precipitation device.
Background technology
Available technology adopting acid ammonium salt precipitation technique makes poly ammonium vanadate (APV).Concrete technological process is the vanadium stoste that contains that adds ammonium sulfate to be sent into vanadium settling tank, and add the vitriol oil on a small quantity.Liquid in the vanadium settling tank is heated and stirs, and detecting simultaneously and keeping the pH value of pot liquid is 2 ~ 2.5.Then liquid is boiled to guarantee to form smoothly poly ammonium vanadate crystal.When liquid level in the tank reaches a vanadium settling tank high position, stop to contain the charging of vanadium stoste; Stop acid adding after pH adjusted to desired value.Continue to open heater block and makes pot liquid be in the state of boiling, allow poly ammonium vanadate crystal grow up and become more solid; Continue boiling time and be not less than 30min.After the stage of boiling finishes, pot liquid is left standstill, time of repose is no less than 30min.After time of repose finished, with the liquid filtering in the vanadium settling tank and storage, the precipitation operation was finished.
