ATEX CONCEPT IN POWDER HANDLING SYSTEMS

Due to the increasingly stringent documentation and controls at an industrial level for the prevention of explosions in industrial plants, the importance of potentially explosive areas classification and preventive measures to prevent successful containment that could be generated by management have been of greater importance. incorrect use of octopuses and grain in NEUMATIC TRANSPORT SYSTEMS.

The protection of a solo system has been wrongly related to the selection of classified electrical elements in the components of a system, however, the ATEX concept goes further. The correct dimensioning of an ATEX system includes from the same classification of the surroundings where the system will be installed to define the paths to follow by an explosion in the event of an event.

An explosion event that took the lives of 14 people was what happened in Imperial Sugar in Georgia USA in 2008, where the explosion generator was a mechanical wheel that increases its temperature by generating ignition.

En muchos casos NO es posible limitar algunos de los 5 elementos del pentágono de una explosión, por lo que se debe diseñar los sistemas con los equipos y fusibles mecánicos en caso de presentarse:

La gran mayoría de productos manejados en la industria en polvo y granos son combustibles lo que genera un riesgo de explosión. Estadística de explosiones de polvo en USA en 2016

    Exothermic reaction (incl. Auto-combustion of organic matter
    Preventions for an eventual explosion must be the sum of the analysis of the area, the analysis of the risk, the appropriate selection of the components of a system and the principles of management of a possible success:
