The spray-type saturator does not consume water
Thread Content
The liquid level in the mother liquor tank does not drop; it decreases by at most 600 mm. No water is added, only acid is added, yet there is still no sign of any consumption of the mother liquor. The gas temperature after the preheater is 65~75°C, and the gas temperature after the saturator is 43~47°C. The ammonium sulfate crystals are small, with the acidity controlled between 3 and 4. The saturator resistance is 6000. Could an expert please explain where the water comes from?
6000 resistance is a bit high, isn’t it?~~
Maintain the mother liquor temperature between 50 and 55 degrees. Check for any leaks in the gas preheater, the water supply valves of the saturator, the cooling water for the mechanical seals of various pumps, the water supply valve of the centrifuge, as well as the wash water valves
6000 Pascals of resistance is too high; we use a spray-type saturator, and its resistance is around 2000 Pascals； The temperature of the mother liquor is a bit low; it should be kept between 50°C and 60°C
