Separation Performance and Structure Optimization of a Novel Corrugated Plate Separator

Abstract

In order to improve the performance of the wet dust removal corrugated plate separator of continuous shearer, a new corrugated plate structure is proposed in this paper. The numerical simulation of air and droplet two-phase flow in the corrugated plate was carried out by using the computational fluid dynamics method. The influence of different structural parameters on the demisting efficiency and pressure loss of the corrugated plate was studied. The results show that the corrugated plate spacing has the greatest influence on the overall performance. Combined with the orthogonal test method, the performance prediction and optimization model of the corrugated plate mist eliminator are determined. A new hybrid multiobjective dragonfly algorithm is proposed to maximize the demisting efficiency and minimize the pressure drop. The multiobjective decision process of the corrugated plate structure parameters is carried out, and the optimal geometric structure of the demister is determined. This study provides a valuable reference for improving the demisting efficiency and the reducing energy consumption of the corrugated plate demister, which is of great significance for wet dust removal in mines.
