摘要:

利用CFD技术对新型套管排气管型旋风分离器的性能进行了研究.在两相流的研究中采用了相间耦合的随机轨道模型.研究结果表明:该新型旋风分离器比普通型的流场的静压分布更有利于阻止灰斗内气流的返混;可排出两种不同含尘量的净化气体,内排气管排出的净化气体的含尘量较外排气管低、且随着内管直径的减小而降低,内排气管的总压降比外排气管大、且随着内管直径的增大而逐渐降低;通过改变内排气管的直径可以控制从内排气管排出气体的含尘量,便于后续分级处理.

Abstract:

The performance of the new casing exhaust pipe cyclone was studied by CFD technology. In the study of two-phase flow, a random orbital model with interphase coupling is adopted. The results show that the static pressure distribution of the flow field of the new cyclone is more conducive to preventing the backmixing of the air flow in the ash hopper than the static pressure distribution of the ordinary type flow field. Two kinds of purified gas with different dust content can be discharged, the dust content of the purified gas discharged from the inner exhaust pipe is lower than that of the outer exhaust pipe, and decreases with the decrease of the diameter of the inner pipe, and the total pressure drop of the inner exhaust pipe is larger than that of the outer exhaust pipe, and gradually decreases with the increase of the diameter of the inner pipe; By changing the diameter of the inner exhaust pipe, the dust content of the gas discharged from the inner exhaust pipe can be controlled, which is convenient for subsequent grading treatment.
