In cryogenic air separation, the liquid level in the middle of the air cooling tower does not rise; instead, it shows a downward trend. If water is added, the resistance of the air cooling tower increases, and the liquid level still does not rise. To reduce the liquid level in the middle, it is necessary to first lower the resistance. Then lower the liquid level, close the drain valve, and the liquid level in the middle will rise quickly. Half an hour later

In cryogenic air separation, the liquid level in the middle of the air cooling tower does not rise; instead, it shows a downward trend. If water is added, the resistance of the air cooling tower increases, and the liquid level still does not rise. To reduce the liquid level in the middle, it is necessary to first lower the resistance. Then lower the liquid level, close the drain valve, and the liquid level in the middle will rise quickly. Half an hour later, the resistance increases; the liquid level starts to drop, or it doesn’t increase at all
It’s about the liquid level in the middle of the tank; the level isn’t at its lowest point. Instead, it is the pressure difference of the tower that decreases first. Then lower the liquid level
Check whether the circulating water is dirty and blocked, preventing air from rising and water from flowing downward
