Combined pneumatic cleaning and aspiration system using vortex dust collectors

Abstract

The article discusses the main calculating methods of the dust removal systems. Calculation and design of systems for cleaning is made taking into account the technological features of the production process and operating conditions, the typical equipment designs use and the units and machines sizes minimum number use. As a rule, the dust deposited on the ceilings of the enterprise has smaller fractions than the dust removed from the nodes of the process equipment. What is important is the parameters selection of the dust collecting apparatus for the dust to be cleaned. So, to adjust the vortex dust collectors, when using the existing aspiration systems, for the dust removal purpose, it is proposed to use a probabilistic-stochastic approach to establish fractional efficiency. The vortex dust fractional collectors’ efficiency depends on the probability of trapping dust particles of a certain diameter in the areas of installations. The procedure for determining the fractional efficiency of vortex dust collectors to adjust the stationary aspiration systems for dust removal is considered.
