Description

{Coanda jet injecting structure for dust collector pulsing}

The present invention relates to a Coanda jet spraying structure for dust collection facility.

The filter bag of the dust collector which is applied to the industrial facilities such as factories and the filter bag of the dust collecting facility is provided with foreign matter such as dust. In order to remove such foreign matter, pulsing which blows strong pressure air in the reverse direction should be performed.

For such pulsing, a Coanda injector is applied as in the conventional patent No. 10-0584101.

The Coanda injector allows the outside air to be sucked into the pulsing object, such as the filter bag, by the coanda effect due to the reverse air blown through the pipe during pulsing.

However, in cases where the height of the dust collector is low, it is often the case that the coanda injector can not be applied. In this case, pulsing to the dust collector is not possible.
