Development of a highly efficient combined apparatus (a combination of vortex chambers with a bin) for dry dedusting of gases
Journal Title: Восточно-Европейский журнал передовых технологий - Year 2019, Vol 3, Issue 10
Abstract
<p>The use of dust collectors of a new type which combine the operation principle of centrifugal and louvre-vortex apparatuses was considered. The use of a heterogeneous reactor for gas-solid systems with two streams in a cyclone, a direct-flow cyclone with a chamber of preliminary collision of gas-dust flows, as well as improved designs of vortex chambers was considered.</p><p>A combined dust collector was presented in a form of the Rankine vortex tube in combination with a bin in which louvre-vortex devices are installed. The combined deduster under study provides an organized supply of a gas-dispersed system at adjustable hydrodynamic conditions to louvre-vortex devices used as the dedusting apparatus. It was assumed that the processes of coagulation of particles under appropriate hydrodynamic conditions as well as partial destruction of harmful gas impurities in a continuous phase will take place in the vortex tube. Thus, development of a substantiated physical model (of a design) of a combined dust collector for specified initial conditions and operability of the design were considered on the basis of theoretical and experimental provisions.</p><p>It has been established that creation of hydrodynamic conditions in centrifugal devices and pipelines is the most promising direction of increasing the degree of dedusting of a gas-dispersed flow. These conditions must ensure supply of the gas-dispersed system to the centrifugal apparatus to ensure agglomeration of fine particles.</p><p>Design of a dedusting apparatus in which intense collision of dust particles in a special chamber and their agglomeration and subsequent separation supposed to proceed in a chamber which is actually a cyclone is an expedient and effective solution. It provides the degree of purification of the gas and dust flow at a level of 98–99 % regardless of particle size.</p>
