Pulse air injection nozzle with dual columnar slits and bag filter dust removal system using same

Abstract

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.

Description

technical field [0001] The invention relates to a cleaning system for a filter dust collector corresponding to the dust collection technology in the technical field of air pollution control. Among various dust collection technologies such as electric dust collection technology, filter dust collection technology, centrifugal dust collection technology and dust washing and dust collection technology, the present invention belongs to the filter dust collection technology that uses a dust collection filter to remove dust contained in process gas . A dust collector that uses filter dust collection technology is called a filter dust collector. The filter dust collector includes a process gas inflow unit, a dust hopper, a dust removal transport and storage unit, a dust collection filter unit, a cleaning unit, a process gas discharge unit and a blower, wherein the present invention corresponds to the cleaning unit. Cleaning in filter dust collection technology means that the dust th...

However, image 3 A disadvantage of the double annular groove nozzle shown in is that the effect of drawing air around the nozzle top into the nozzle is reduced because the injection through the inner groove 404 does not follow along the curved surface but is directed directly to the vertical underside, And the suction effect of the surrounding air is reduced, because the injection through the outer groove 404 is not carried out along the curved surface but along the vertical slope of the lower guide 402

A disadvantage of the double annular groove nozzle 400 is also that it has an external shape that is difficult to connect to the injection tube 405
