SUPERVISION AND 4.0 PLANTS MANAGEMENT
There are numerous processes for the production of wood base panels and each generate different types/characteristics of pollutants which require treatment.
The so-called green area is where mills are connected to suitable bag filters for the abatement of humid pollutants, via reinforced ducts. This detail is fundamental as otherwise the system would suddenly block.
The dry area is where dry mills are connected to and it is from here that all material is pneumatically conveyed to cyclone filters. High concentrations of powders results in considerable wear, especially to curves, which are fitted with square brackets with interchangeable back, which are very thick. Complex, high-technology systems are used to detect any sparks and guarantee good reliability.
The panel pressing line generates a vapour-dust mix which is sucked up using high head grasps (for enhanced capturing effect) and sent to a water filter with venturi with a downstream pollutant collection tank.
Remaining forming/cutting/calibrating lines are sent to respective pulse jet bag filters.
Filter dust exhaust is sent via very high head volumetric blowers to storage silos, where it is reused as fuel for boilers (powders) or for panel formation (chipboard). In these specific cases, pneumatic lines are made from thick metal sheet and curves are entirely coated with ceramic material.
There is particular focus on the characteristics of treated material insofar as it is classified by 2014/34/EU as potentially explosive, class St 1.
