Selection of flow rate for the circulation pump associated with the exhaust gas spray scrubber tower
Thread Content
Let’s discuss how the flow rate of the circulation pump used in the exhaust gas spray scrubber tower is determined.
It mainly depends on the amount of components in the exhaust gas that need to be removed or absorbed, taken together with the absorption efficiency of the cleaning medium
Is there a simpler way? If calculated that way, there are too many parameters that need to be checked
The tower diameter is calculated based on the air volume. By combining the spray density, it is possible to calculate the spray volume, that is, the circulation volume. Spray volume = Spray density × π × (tower diameter^2) × 0.25. If there are empirical data available for the spray density, it can be used directly; otherwise, it is necessary to determine whether the spray density is appropriate by conducting a flooding calculation, in order to establish the final spray density
Spray density – it’s something that needs to be understood: P
In past projects related to the stripping of wastewater with high ammonia nitrogen levels, it was understood that the gas-liquid ratio is a crucial parameter. In the operation of spray absorption, which is the opposite of stripping, can the gas-liquid ratio also serve as an important parameter for determining the flow rate of the liquid pump?
The gas-liquid ratio is also an important parameter
