射流曝气器充氧性能研究

Study on the Oxygenation Performance of the Jet Aerator

本文分析了射流曝气器的充氧作用与理论,并进行清水充氧试验以测定其性能。试验结果表明,其氧动力转移效率和氧利用率均高于鼓风曝气法。并对射流器的安装高度和喉嘴比对氧动力转移效率的影响与喷口压力对吸气量的影响作了探讨。

In this paper, the oxygenation of the jet aerator and its machanism are discussed. The results from tests on performance (in clean water) are provided. Results show that both the efficiency of energy utilization and the efficiency of oxygen transfer are higher than those of the blower aerator. Investigations have also been made on the impacts of installing position, the ratio of cross section area of the tube to that of the nozzle (where jet is formed) on the efficiency of energy utilization, and the impact of the pressure at the nozzle on the quantity of air sucked.
