摘要：引言 工程实践中，在满足分离精度的同时还要保证其处理能力，就需要采用多个微旋流器进行并联配置。因此微旋流器组并联配置是工程放大应用的必要手段。
It is common to use multiple mini-hydrocyclones in parallel arrangement for large-scale industrial applications. For two typical parallel arrangements in mini-hydrocyclone group, U-U type and Z-Z type, the characteristics of pressure drop and flow distribution were investigated and compared by using theoretical model and experiments. It is found theoretically that the value of Q3 q_R2 has great influence on the performance of both parallel arrangements, where Q and R represent the momentum and the friction effects. The performance of U-U arrangement is better if Q^3 ＋ R2 〈 0, while that of Z-Z arrangement is better if Q3 q_R2 ~0. The experimental results show that the Z-Z arrangement presents better pressure drop distribution than the U-U type for 0.05≤P〈0.10 MPa, but the flow distribution of both parallel arrangements is non-uniform under the condition. At P = 0.10 MPa, uniform pressure drop and flow distribution are found for both arrangements. For 0.10〈P≤0.15 MPa, the flow distribution of U-U arrangement is more uniform than Z-Z type. The pressure drop distribution of both arrangements has the same trend and is good.
