Numerical simulation and optimization of internal circulation anaerobic reactor by Fluent software
摘要
Abstract
The process of gas-liquid two-phase flow of internal circulation anaerobic (IC) reactor (25L)was simulated by Fluent software. The influence of internal circulation flow rate with different riser pipe diameters (0.006m,0.009m,0.012m,0.015m,0.018m,0.021m)and volume loading rates [8.64kgCOD/(m3·d) , 10.08kgCOD/(m3·d) , 11.52kgCOD/(m3·d) , 12.96kgCOD/(m3·d) , 14.40 kgCOD/(m3·d) , 15.84kgCOD/(m3·d)] were investigated. When volume loading rate was 11.52kgCOD/(m3·d),and riser diameter was 0.015m,a maximum internal circulation flow rate of 0.0079m3/h was observed. When riser diameter was 0.015m,and volume loading rate was 12.96 kgCOD/(m3·d) , a maximum increase amplitude of 9.28% was observed. The correlation of Y=1.0514X+0.004 between internal circulation flow rate(Y) and biogas production(X) was obtained by fitting.关键词
