Ammonium sulfate saturator
Thread Content
What is the cause of backflow in the full-flow tank of the ammonium sulfate saturator?
Reply to 1# cclj: 1. Add acid, 2. Add mother liquor. 3. Add spraying points in the pre-chamber of the saturator. It is mainly to replenish fluids
It returns to the mother liquor tank, not in a full flow
An excess amount of make-up mother liquor, leaks from steam or water distribution boxes into the saturator, or failure to turn off the centrifuge rinsing water all affected the balance of the mother liquor.
There are various reasons, including controlling the liquid level – isn’t there a cyclone separator there?
Reasons: 1. Imbalance in the mother liquor level balance; pay attention to the gas temperature and the mother liquor temperature. 2. Whether the drain water valve of the water bath dust collector is in the open position. 3. Is the selection of the small mother liquor pump appropriate? 4. Is the downcomer blocked?
Reply to 6# Xiaohongchen: Does a preheater temperature of 94 degrees Celsius affect the reflux of the mother liquor?
If the temperature of the gas after the preheater is high, it will still affect the level balance of the mother liquor; it will increase the amount of mother liquor carried by the gas. Strictly speaking, this will have a slight impact on the amount of mother liquor that returns, but there is no problem as long as liquid is replenished in a timely manner. It is important to note that a high gas temperature will raise the temperature of the mother liquor, which in turn affects the growth of crystals; this results in smaller crystal particles and more nuclei. If the material is not removed in time, it can cause blockages in the pipes or downcomers of the saturator, thereby affecting production.
Used to replenish the mother liquor and adjust its acidity
Does the ammonia gas produced after ammonia evaporation enter the saturator? A high pressure in the ammonia evaporation tower causes the ammonia gas to contain water
In our workshop, the level of the liquid in the flow tank is usually below the outlet through which it overflows into the mother liquor storage tank; overflow occurs only when acid is added to prepare the mother liquor.
