Effect of Air Humidification on the Pumping Efficiency of Water in a Packed Column Humidifier
Year: 2015
Type: conference-paper
Abstract: The effects of water temperature on the discharged liquid flow rate, pumping efficiency, gas holdup and slip velocity were examined for an airlift pump with a riser filled with packing. Comparing with ordinary airlift pumps operating in ordinary conditions, the humidification of contributes positively in the increase of pumped water flow rate and saving energy. In this study, for the purpose of high pumping efficiency, several water temperatures were tested for many submersion ratios and gas flow rates. The results show that the increase of water temperature causes air humidification, gas holdup and high Reynolds number. Or the pumped liquid flow rate and slip velocity increase with the gas holdup growth. Therefore, the pumping efficiency will be higher with air humidification.
