Abstract
A nozzle for a filter cleaning system has a stub portion having an inlet opening and an outlet opening, and a splitter portion positioned downstream of the stub portion. The splitter portion has deflector surfaces arranged to direct the airflow exiting the stub portion outlet in 3 or more different/separate airstreams each of which airstreams are directed inclined axially outwardly from the axial direction of the airflow exiting the stub portion outlet opening. The various parameters of the splitter nozzle portion can be tailored to provide required jet shape and entrainment characteristics. A beneficial feature of the nozzle designs is that jet entrainment and recombination of flows can be specified for different shaped filters.
