Graduation project on flue gas treatment
Thread Content
For a 300MW coal-fired power unit, the flue gas volume calculated is 1.1 million m³/h. When desulfurization is implemented, the diameter of the packing tower is assumed to be 12m and the height of the packing layer is 6m. Is such a result normal?
Based on my personal experience, the ratio of the diameter to the height of this packed tower seems to be inappropriate. The height of a packed tower should generally be about 3 to 5 times its diameter; in this case, the proportion of the packing layer height to the overall height of the packed tower is also relatively high. Therefore, it may be necessary to recalculate the diameter and height of the packed tower, as well as the height of the packing layer, to ensure maximum flue gas treatment efficiency. Additionally, when calculating the amount of flue gas, other factors such as temperature, humidity, and wind speed must also be taken into account to obtain more accurate results. At the same time, when selecting a desulfurization process scheme, it is necessary to consider the actual circumstances, choose an appropriate process scheme, and make suitable adjustments and optimizations to it, so as to ensure an optimal balance between desulfurization efficiency and economic viability. .
This height-to-diameter ratio should be unreasonable
Thank you. I replaced the previous packed tower with a spray tower and recalculated the dimensions. The calculated tower diameter is 11m, and the height of the spray tower is 40.52m. I wonder if these dimensions are appropriate this time?
The tower diameter is related to the empty-tower gas velocity; it has little relation to the packing. Therefore, determining the gas velocity is crucial, and various factors must be taken into account. The packing height is determined based on the height calculated according to your efficiency, etc. The value you obtained is unreasonable; consequently, the calculation result is also unreasonable
