Title: Apparatus and method for improved pulse-jet cleaning of industrial filters

Abstract: An improved apparatus and method for pulse-jet cleaning of filter bags in a baghouse using pulsed, high-pressure/low-volume, intermediate-pressure/intermediate-volume, or low-pressure/high-volume pulsed air flow. Rotation of one pipe relative to another pipe about a shared longitudinal axis causes apertures in the pipes to align intermittently. When the apertures are aligned, pressurized air is fed, through a pulse valve, into the inner tube of the two and flows out of the nested pulse pipe arrangement in a short, energetic pulse. The pulse is directed down into a filter bag arranged below the pulse pipe to pulse-clean the filter bag.
