Drop in the level of the stripper causes the reflux tank to become full
Thread Content
The stripping unit uses around 7 tons of steam, with a feed volume of only about 35 tons. Recently, however, the acidic water goes straight into the reflux tank as soon as it is introduced, and the liquid level in the stripping tower also drops. (The previous method involved injecting fresh water first and then treating it with steam from the tower; fresh water was used as the feed water in amounts of around 30 tons, and it passed through the reboiler at the bottom of the tower. The outlet flow rate was several tons per unit time. If the liquid level in the reflux tank rose suddenly or if the temperature at the bottom of the tower reached around 160 degrees, the amount of liquid drawn off was increased.) White crystals along with black, viscous substances were found in the filter of the purification water pump. Once the feed volume and the output volume became equal again, we started using acidic water once more. Now, the liquid level in the reflux tank is rising sharply again until it reaches full capacity. I would appreciate it if someone could tell me whether the stripping tower is blocked or if there is a problem with the amount of feed water supplied!
Your statement should be changed to: Due to too many impurities in the raw materials, the stripping tower gets clogged, or at least its operation is impaired!
I’m going to try the method from last time again; if it doesn’t work, I’ll have to prepare to stop steam stripping and proceed with feeding material into the tower
The problem is probably that the tray is clogged! Shut down to remove trays and clean them! Also, do not use fresh water, as it contains large amounts of calcium and magnesium ions; under high temperatures these ions form calcium carbonate and magnesium carbonate, which can more easily cause blockages in the trays! If using water for rinsing, it’s best to use demineralized water!
