Performance of cylindrical-conical cyclones with different geometrical configurations

Abstract

The present work is a continuation of a study of the influence of geometric characteristics on the performance of reverse-flow cylindrical-conical cyclones. After studying the behavior of the pressure drop in previous work (Arnosti et al., 1998), here performance in terms of collection efficiency in the removal of particulate material is addressed. The independent variables considered in this study were inlet gas velocity (three velocities) and the following dimensions of the cyclone: the cylindrical section (three heights) and internal height of the gas exit duct (three heights). The tests were performed using an 3³ experimental design. Analysis of the results for overall efficiency was carried out using response surfaces and the statistical parameters were estimated from linear regression

Analysis of the efficiency of purification of gas flows in a centrifugal filter

“…In the method [7], an attempt is made to consider the features of flows in the device, wall friction, multifractionality and input concentration of solids on the characteristics of the particulate collection in cyclone devices. The work [8] proposes a statistical correlation for evaluating fractional efficiency, which is satisfactory agreed with experimental data for cyclones of different geometry.…”

Investigation on particulate matter and gas motion processes in the advanced multi-channel cyclone-separator with secondary gas inlets

“…Muschelknautz,and Trefz [15] attempts to take into account the singularities of the flow adjustment device, the friction of the walls, multi-fractionality and the concentration of particulate matter entering collection devises of the cyclone. The paper [16] proposes a statistical correlation of assessing fractional effectiveness satisfactorily compatible with experimental data on the cyclones of different geometry.…”

Mathematical modeling of cleaning dust-laden gas flows in the cyclone dust collector

“…В [8] запропонована статистична кореляція для оцінки пофракційної ефективності, що задовільно узгоджується з експериментальними даними для циклонів різної геометрії. Тут також відмічено, що рівняння для пофракційної ефективності [9], широко відоме в літературі, не може бути рекомендовано для низьких величин конструктивного фактору К та випадків оцінки ефективності циклонів при великих змінах в їх конструкціях.…”
