OXYGEN SUPPLY PERFORMANCE OF GAS-INDUCING AGITATOR SYSTEM FOR AUTOTHERMAL THERMOPHILIC AEROBIC DIGESTION PROCESS

Department of Bioscience and Biotechnology, Kyushu University, Fukuoka 819-0395, Japan

摘要

摘要: 将曝气搅拌一体式自吸式曝气搅拌装置应用于自热式高温好氧消化（45~65 ℃）系统，并与传统曝气搅拌分离式的盘式涡轮搅拌装置进行对比，系统考察了2种曝气搅拌装置的供氧性能与经济可行性。结果表明：自吸式曝气搅拌装置适用于搅拌速度为500~1100 r/min，过低或过高的搅拌速度都会影响系统的供氧能力；当搅拌速度为900 r/min，曝气量为0.5 L/min（通气率）时，盘式涡轮搅拌装置的K_Lα值为108.01 h^-1，低于同条件下的自吸式曝气搅拌装置。盘式涡轮搅拌装置在相同曝气条件下，50 ℃时的K_Lα值高于30 ℃时。在1000 r/min转速下，为实现相同的K_Lα值，自吸式曝气搅拌装置的电能消耗约为盘式涡轮搅拌装置的1/3。

Abstract: Gas-inducing agitator system and disk turbine agitator system were applied to autothermal thermophilic aerobic digestion system; this study compared the oxygen supply performance and economic feasibility of these two agitator systems. The research showed that the gas-inducing agitator system was suitable for a stirring rate of 500~1100 r/min, a lower or higher stirring rate would affect the oxygen supply performance; with a stirring rate of 900 r/min and air flowrate of 0.5 L/min (by volume), the K_Lα value of the disk turbine agitator system was 108.01 h^-1, lower than that of gas-inducing agitator system of 124.52 h^-1; disk turbine agitator system under the same stirring rate and air flowrate, K_Lα value at 50 ℃ was greater than that of 30 ℃. To achieve the same K_Lα value under 1000 r/min, the power consumption of the gas-inducing agitator system was about 1/3 of that of the disk turbine agitator system.
