Flow Type

Gas-liquid screen, a novel liquid-gas two-phase flow type, is applied in a scrubber for WFGD. According to the characters of the flow type, heat transfer experiments have been conducted to study the temperature distribution of flue gas in the tower and find the relation between heat transfer coefficient, flue gas and liquid velocity. The results show that whether in concurrent or countercurrent tower the heat transfer coefficient will increase with L/G decreasing at a fixed gas velocity. The optimum position of heat transfer is at the top of the Gas-liquid screen. So multilayer ‘Gas-liquid screen’ could to be arranged to optimize the effect of heat transfer and reduce the industry cost. The formulas of the relation between heat transfer coefficient, flue gas and liquid velocity are gained. These can provide strong foundation for the engineers and the further mass transfer experimental study.
