PULSE AIR INJECTION NOZZLE WITH DUAL COLUMNAR SLITS AND BAG FILTER DUST REMOVAL SYSTEM USING SAME

摘要

The present invention relates to a pulse air injection nozzle with dual columnar slits and a bag filter dust removal system using the same, in which the dust removal effect of a dust collector filter can be remarkably improved by introducing massive peripheral air with a small amount of compressed air, and more specifically, to a pulse air injection nozzle with dual columnar slits and a bag filter dust removal system using the same, wherein: internal horizontal columnar slits are formed inside in the upper part of an injection nozzle having an overall cylindrical shape; each of external vertical columnar slits is formed on the outer boundary of the injection nozzle; air currents injected from the internal horizontal columnar slits rapidly flow in a vertical downward direction along a curved surface whereby air pressure inside a cylinder is reduced to allow peripheral air in the upper part of the nozzle to flow into the inside of the nozzle quickly; and air currents injected from the external vertical columnar slits rapidly flow along a curved surface formed toward the inside of the cylindrical nozzle whereby air pressure around the outer side of the nozzle is reduced to allow the peripheral air to be enticed along the outer side of the nozzle, thereby increasing a flow of the overall pulse air introduced into the inside of the dust collector filter. Consequently, the invention is capable of highly improving the dust removal efficiency for removing dust attached to a surface of the dust collector filter.
