JET NOZZLE FOR BAGFILTER CLEANING

摘要

The present invention relates to a jet nozzle for cleaning a bag filter, which is coupled to a blow tube supplying compressed air for dedusting dust collected in the bag filter by supplying the compressed air to the bag filter. The jet nozzle for cleaning the bag filter includes: a discharge tube coupled to an outlet of a blow tube to provide dedusting airflow while discharging compressed air toward the bag filter; a cone shaped guide tube fixed to accommodate a part of the discharge tube to form a separated space with the discharge tube, guiding the compressed air discharged from the discharge tube to an inlet of the bag filter and introducing peripheral airflow of the discharge tube through the separated space to increase the flow rate of the dedusting airflow, and having a diameter getting narrowed toward the bag filter to increase flow speed of the dedusting airflow; and a discharge tube fixing piece for fixing an outer circumference surface of the discharge tube to be spaced apart from an inner circumference surface of the guide tube.
