Hycontrol's Hyvent dust collector and filter unit has been designed to vent silos during the filling process without allowing the valuable powdered product to escape. Filtration occurs during both the conveying period and the air surge at the end of the cycle. The filter is self-maintaining, returning powder into the silo via an automatic reverse-jet pulse cleaning system which utilises compressed air.
This silo filter unit features the latest technology in conical-shaped filter design. This patented cone shape provides outstanding cleaning efficiency while enabling maximum airflow through the unit and has the added benefit of an increased life for the cartridges. They offer many advantages over traditional cylindrical cartridges or bag filters. Hyvent provides a compact design, higher filtration efficiency and superior dust pre-separation. The tapered shape increases separation; this results in reduced up-stream air velocities, increased pre-separation and lower dust re-entrainment. This bin vent filter unit is built for safe and simple maintenance and has a rugged weatherproof construction.
Hyvent has been designed to the latest guidance from the Mineral Products Association (MPA) and to meet HSE guidelines on preventing over-pressuring storage silos during deliveries. It complies fully with environmental emission standards and can filter all types of powders. Hyvent forms an integral component of Hycontrol's advanced SHIELD Lite silo protection system, providing the ultimate defence against the dangers of overfilling and over-pressurisation in powder silos for products including cement, ash, ready mix concrete, lime, fly ash, GGBS and more.
The conical cartridges utilised in the Hyvent dust collectors offer many advantages over traditional cylindrical cartridge or bag filters due to their compact design, higher filtration efficiency and superior pre-separation of dust. The tapered shape allows increasing separation from top to bottom between the filter elements inside the unit resulting in reduced upstream air velocities, increased pre-separation and lower dust re-entrainment. In addition, the tapered inner core of the filter element enhances the effectiveness of the compressed air jet and gives a more even clean over the length of the cartridge.
This unique design means that 82% of the area at the inlet chamber of the filter unit is free, as opposed to a typical 59% when using cylindrical elements. In addition, lower upward air velocities at this point mean an increase of dust separation. These features mean the filters have a longer functional life and offer a higher consistency of performance.
