Title:
LOCAL HOOD EXHAUST PRESSURE DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/129786
Kind Code:
A1
Abstract:
The present invention relates to a local hood exhaust pressure device. Horizontal suction fans are disposed at one end of an exhaust hood, along the length of each side of the hood in the vertical and longitudinal directions. Polluted stagnant air around the end of the hood that has not been exhausted is exhausted, and does not spread inside due to the air layer that is an air jet. The air in the spread angle of the airstream of an air jet discharged from each side surface of a lower heat source system by the suction fan is pushed at an inclined surface angle inside the hood by the suctioned discharge air. All of the fans are jointly operated at the same time such that the air is discharged rapidly by a guide collar for airstream attraction in the hood, and thus the polluted air is pushed and drawn.
