Biomass dryer/burner system

摘要

The present invention provides a biomass dryer/burner unit having an air cleaning apparatus adapted to accept emissions from unit and to convert said emissions to clean air to meet government emission standards. The air cleaning apparatus including a spray scrubber fluidly connected to the unit adapted to moisten emissions, a recirculation tank in fluid communication with a collection tank, angled baffle plates, and the collection tank further having a sensor adapted to measure contaminant levels contained within the recirculation air filtration system. If the air contained within the collection tank measures above a predetermined contaminant level, then the air contained within the collection tank is directed back into the spray scrubber. If the air contained within the collection tank is below a predetermined level, then the air is exhausted into the atmosphere. Water is further allowed to recirculate back to the spray scrubber.

主权项

1. A biomass modification system having an air filtration apparatus and recirculation system adapted to accept emissions to scrub said emissions to meet air quality standards, said air filtration apparatus comprising:
a biomass modifier, the biomass modifier operable to accept and modify biomass, the biomass modifier producing emissions; a spray scrubber fluidly connected to the biomass modifier, the spray scrubber to moisten the emissions from the biomass modifier; a collection tank having a floor contained therein allowing sediment to settle on the floor of the collection tank, the collection tank having at least one baffle plate, the baffle plate angled to encourage air flow, the at least one baffle plate mounted to the ceiling of the collection tank, the at least one baffle plate being v-shaped to facilitate air-flow through the collection tank; the collection tank having a sensor connected to a valve, the valve connected to the collection tank, the collection tank fluidly connected to the spray scrubber and an exhaust fan, the valve discharges the emissions if the contaminant level measuring sensor reads below a predetermined level through the exhaust fan, or pumping the emissions back to the spray scrubber if the contaminant level measuring sensor reads a level above a predetermined level; and a recirculation tank fluidly connected to the collection tank, the recirculation air filtration system having at least one filter, the recirculation tank in fluid communication with the spray scrubber to move water from the recirculation tank back to the spray scrubber.
