CONTROL METHOD OF AIR FLOW SEPARATION AT SUCTION PASSAGE INLETS

摘要

FIELD: ventilation.SUBSTANCE: control method of air flow separation at the suction passage inlet consists in action on the flow of a shield installed at the passage inlet perpendicular to its axis and a mechanical screen with a central hole, which is located before the suction passage on one axis and perpendicular to the passage axis.EFFECT: increasing resistance of the air entering suction holes, reducing consumption of the air supplied to them, which can be useful for reduction of volume of the air entering through leakages to aspiration hoods or to open transport passages.4 cl, 2 dwg
