CONTROLLED PULSE AIR FILTER SYSTEM

摘要

An air filtering system and method for self-cleaning the same is provided. The system has a plurality of air filters including a first filter and at least one neighboring filter. A blower fan pulls air through the filters. A plurality of compressed air injectors are provided adjacent the filters including a first injector and at least one neighboring injector. Self-cleaning is achieved while the blower fan is running by preforming several steps including activating the first injector to force compressed air into the first filter and discharge particulate from the first filter followed by deactivating the first injector. The steps further provide reactivating the first injector and simultaneously activating the neighboring injector while the discharged particulate is airborne to provide an air shield about the first filter and force the discharged particulate away from the first filter and the neighboring filter. These steps are repeated for each filter.

主权项

1. A self-cleaning air filtering system, comprising;
a plurality of air filters including a first filter and at least one neighboring filter adjacent said first filter, a plurality of compressed air injectors including a first injector and a neighboring injector for each neighboring filter for forcing compressed air into said air filters, a programmable logic controller operably connected to said compressed air injectors to actuate said compressed air injectors and said control unit being programmed with executable instructions including activating said first injector to force compressed air into said first filter and discharge particulate from said first filter and deactivating said first injector and reactivating said first injector and simultaneously activating said at least one neighboring injector while the discharged particulate is airborne to provide an air shield about said first filter and force a portion of the discharged particulate away from said first filter and said at least one neighboring filter.
