Patent attributes
A method of cleaning exhaust gasses, including first placing a plurality of filtration modules into a housing to define a filtration bed, then weighing the filtration bed to determine an unladen weight, filling the filtration bed with filter media to define a laden filtration bed, and weighing the laden filtration bed prior to exposure to exhaust gas. Next, calculating the weight of the filtration media prior to exposure to exhaust gas to determine an initial weight of the filtration media, directing exhaust gas through an inlet into a housing, directing exhaust gas from the inlet through the filtration bed, removing particulates and chemicals from the exhaust gas to define a cleaned gas, and directing the cleaned gas through an outlet. While cleaning the gas, periodically measuring the weight of the filtration bed and calculating the weight gain of the filtration media. When the weight gain of the filtration media exceeds a predetermined value, defining the filtration media as spent media and emptying each respective module of spent media into a container to yield a plurality of respective empty modules and a filled container.
