A research group led by Hong Sang Ryong, a researcher at the Faculty of Heat Engineering, has been working hard to make further achievements since he established an energy-saving recirculation system for dust collection and ventilation that can keep clean environment at the working places in a timber mill.
The system makes it possible to reduce power assumption to the minimum by adjusting the number of ventilators and dust collectors to the operation rate of wood working machinery.
They determined reasonable working parameters of the air control valve to prevent deposit of rough wood chips in the pneumatic conveying pipe.
They also selected optimal jet time and close-down time of the pulse system in the dust collector.
As a result, they reduced the number of working ventilators and dust collectors and ensured a long working life of the bag filter, which led to high working safety and low operational cost of the dust collection and ventilation system.
