NUMERICAL MODELING OF DUST EMISSION AREA INFLUENCE ON AIR POLLUTION IN A LABORATORY CRUSHING ROOM
Abstract
With three units of laboratory equipment (jaw and roller crushers, as well as rotary ore divider) operating simultaneously, numerical modeling research was performed to examine the effect of dust emission area on air pollution in a laboratory crushing room. The modeling was performed in a three-dimensional setting using the COMSOL program. The room ventilation process was modelled based on a previously developed two-stage methodological approach: calculation of aerodynamic parameters in the incompressible fluid approximation using the standard (??-??)-turbulence model, as well as solving the convection-diffusion equation taking into account the dust settling rate. The model basic parameters were recorded: the dimensions and location of the laboratory equipment, as well as the supply and exhaust ventilation ducts; the duration of laboratory equipment operation 1 h; the deaeration rate provided by the use of a VR 300-45-4 fan; the design dust intensity generated from the upper horizontal surface of the equipment. The dust emission area was varied by reducing one side and keeping the other unchanged. The maximum and average dust concentration in the crushing room was analyzed, as well as the spatial distribution of pollution depending on the dust emission area.
