Spray tower deodorization circulating liquid tank
Thread Content
In an odor treatment system that uses a spray tower for treatment, there is a surge tank between the circulating liquid at the bottom of the spray tower and the circulation pump. The flow rate of the circulation pump is 80 m3/h; how can the size of this surge tank be calculated based on the pump’s flow rate? Friends with experience in this area, please give some advice. Thank you!
Based on the dwell time buffer, it is generally within 10-30 MIN
Mm-hmm, so it’s really an experience value after all
This is similar to wet air cooling – one calculates the residence time of water in the tank, or does similar calculations for intermediate tanks; generally, 10-30 minutes is taken as a value. Of course, if there are special requirements in the process, this time period can be increased. The standards are merely for reference purposes; as long as the process complies with those standards, it should be based on the requirements of the process itself. Otherwise, when a new process is developed, there are no standards yet – everything is determined through experience and accumulated data
Did I misunderstand? It’s completely absurd to require 10 minutes’ worth of water for this transition tank. It’s probably just a negative pressure tank to prevent the pump from failing to start; a capacity of a few hundred liters is sufficient
