A ferrosilicon foundry operates a warehouse to store different grades
of finished products before their truck shipments. During material transfer operations to
and from storage, large amounts of dust are suspended in the air.
The dust clouds formed then dramatically reduce the visibility in the
warehouse, which creates health and safety risks to workers and sometimes force the
temporary shutdown of operations in the warehouse while the cloud dissipates.
- Identify the techniques and technologies of ventilation / dust collector
applicable to the warehouse to solve the problem of visibility.
Size the required equipment to ensure an optimal operation and secure system.
Four ventilation and dust collector techniques were evaluated during this study to address
the problem of visibility in the warehouse. For each configuration of the ventilation /
dust collector system, the various equipment components of the warehouse ventilation/dust
collector network have been dimensionned in a preliminary study (ducts, fan, dust collector
system, fire & explosion prevention system, instrumentation, etc.).
Finally, an estimate of the acquisition and installation
costs of each configuration was made to identify the method and configuration that, in
terms of cost and longevity, is the best solution for this application.
At the end of this study, the combination of a push and
pull ventilation system and a multi-cyclone was determined, in terms of cost and
robustness, as the configuration suited for this application. Preliminary dimensioning of
ventilation equipment, dust collector and fire & explosion prevention corresponding to this
configuration has also been realized.
