Experimental and numerical studies in elaboration the multi-cyclone with filter cells to processing of flue-gases of coal-fired and incineration power plants

Abstract

Currently, in various industries for both sanitary and technological treatment of heterogeneous flows, as a rule, several devices are used that consistently provide the coarse and fine stages of gas clean up. For example, to prevent the penetration of mechanical (solid and liquid) impurities to the measurement instruments, regulation, control and automation at compressor stations of gas transmission systems the gas cleaning units are setup. They consist of two types of apparatus - cyclone dust collectors and filters. Similar gas cleaning devices are at booster compressor stations of TPPs. In this paper, we consider the effectiveness of using a multi-cyclone apparatus for such purposes, the elements of which combine both stages of cleanup. The problem of finding the optimal arrangement in the apparatus of cyclone elements with tangential inlet branch pipe is solved. A numerical model of the multi-cyclone is created and several variants of the arrangement of elements are considered. The most effective arrangement was determined taking into account the total hydraulic resistance of the apparatus and the trajectories of the motion of suspended particles.
