Abstract
The present invention relates to a pulse-jet cleaning device for filter with a self-oscillating nozzle, in which a tube sheet of the filter is provided with a filtration unit thereon, with a cleaning gas chamber above the tube sheet and a dust-containing gas chamber under the tube sheet; and the pulse-jet cleaning device includes an ejector and a back-flushing pipeline, with one end of the back-flushing pipeline connected to a back-flushing gas tank through a pulse back-flushing valve, the other end of the back-flushing pipeline being provided with a self-oscillating nozzle corresponding to the top portion of the ejector; and the self-oscillating nozzle includes a hollow cylindrical self-oscillating chamber, which has a gas inlet at an upper end connected to the back-flushing pipeline and a gas outlet at a lower end.
