Design parameters of cyclone plate gas scrubbing cooling towers
Thread Content
The existing waste incinerator burns flue gas at a temperature of around 300°C, with a flue gas flow rate of 15,000 m3/h. It is planned to use a swirl plate tower with alkaline lime water spray to cool the gas and absorb the harmful acidic gases present in it. May I ask how many layers of swirl plates are appropriate to install in the entire tower? What should be the empty-tower gas velocity and gas-liquid contact time for the flue gas? Additionally, what values should be chosen for the dosage of lime-alkaline water (liquid-to-gas ratio) and the spraying density? It is capable of achieving the process objectives of cooling the flue gas to 50–70°C and effectively absorbing and removing harmful acidic gases from the flue gas. Thank you all for your help and advice.
Can the swirl plate meet the resistance drop requirements? We have a low-resistance spray tray that should be considered.

The single-layer pressure drop ranges from 200 Pa to 300 Pa, making it highly suitable for conditions with a small volume of liquid and a large volume of gas when it comes to absorption
For cooling water vapor, could you recommend a cooling spray tower?
