Abstract
A comparison of the level of circular velocities and velocities of turbulent transfer in a coaxial channel and a countercurrent cylindrical cyclone is performed. Comparison of dust separation efficiency in these apparatuses is made.
Highlights
Cylindrical cyclone chambers are used as technological devices for burning, melting, drying, high-temperature reactions [1,2,3,4,5,6,7], they are used as dust concentrators in gas cleaning systems [8, 9], in installations of dust removal of air of systems of aspirations [10, 11]
Calculations of the effects of dust separation in a coaxial channel along particle trajectories have shown that efficiency decreases with decreasing distance between cylinders
In separators with tangential input and an elongated coaxial channel, the swirling flow is asymmetric, the tangential velocities are less important than the input speed and are not symmetrical, the separation of particles is effected by centrifugal forces and turbulent transfer, which plays a decisive role
Summary
Cylindrical cyclone chambers are used as technological devices for burning, melting, drying, high-temperature reactions [1,2,3,4,5,6,7], they are used as dust concentrators in gas cleaning systems [8, 9], in installations of dust removal of air of systems of aspirations [10, 11]. There is a wide variety of devices with built-in elements forming coaxial channels with constant or variable cross-sections for separating particles from a swirling gas stream: cyclones of LIOP (Leningrad Institute of Labor Protection), Institute of Siindmashcoalenrichment [9], cyclone with intermediate dust extraction [12]. In the elements of battery cyclones, there is a stabilization section of the swirling flow, which is a coaxial channel, in which the particles are “pressed” to the periphery [13]. In the cylindrical part of the cyclone with an extended dip tube, the gas makes several revolutions in the coaxial channel, the variation in the flow parameters in the circumferential direction is insignificant and, on the whole, it is believed that the aerosol motion is axisymmetric. The aim of the study is to distribute the circumferential velocities and to determine the separation efficiency for cylindrical cyclones with different coaxial channel lengths
