Modular up-draft pressure pulse bag house

A bag house air filtration system with minimal recirculation uses new inlet airflow patterns and cleaning processes. Inlet air enters the bag house. An input plenum changes the velocity profile. Dirty inlet air is split into two plenums, and then passed through guide vanes. A clean air plenum contains a series of individual compartments with a pre-set number of filter bags that are effectively cleaned during a single cleaning cycle. Each individual compartment has a door or louver mounted above the bag openings that is opened and closed during the cleaning cycle. An automatic control system continuously senses bag house pressure drop and activates the cycle when needed. The doors open and close in a pre-set pattern to drop the dust cakes from the bags and restore air flow to normal pressures. Closing a door mounted above the bags creates a reversal of pressure that removes the dust cake.
