The straight through finned cyclone tube is the key component of the air filter prefilter, and is the core that determines the separation efficiency of the prefilter. Based on the working principle, de-sign theory, and mathematical model of flow field of a certain type of straight through finned cy-clone tube, this paper compares and collates bench test and field test data to form an empirical de-sign mathematical model of straight through finned cyclone tube, and programs it to form a design software. It studies the impact of design parameters on its performance such as resistance and effi-ciency, and determines the optimal value range of relevant parameters to realize accurate calcula-tion of the performance of the straight composite cyclone tube, and achieve the purpose of improv-ing the comprehensive performance of the prefilter.
