<p>An improved apparatus and method for pulse-jet cleaning of filter bags (14) in a baghouse (12) using pulsed, high-pressure/low-volume, intermediate-pressure/intermediate-volume, or low-pressure/high-volume pulsed air flow. Relative movement between a first tubular member (302) and a second member (304) causes apertures (340, 342) in the members to align intermittently. When the apertures are aligned, pressurized air is fed, through a pulse valve or from a combustion chamber, into the tubular first member (302) and flows out of the aligned apertures in a short, energetic pulse. The pulse is directed down into a filter bag (14) arranged below the pulse pipe (300) to pulse-clean the filter bag or into another pulse pipe (380) arranged above a filter bag.</p> |
