Claim:
A chimney filter system ( 100 ) comprising: (a) a first filter housing ( 110 a ) adapted to be mounted atop an industrial chimney stack ( 101 ), and a third filter housing ( 110 c ) disposed atop the first filter housing ( 110 b ), the filter housings ( 110 ) allowing for gas flow from the chimney stack ( 101 ) through the filter housings ( 110 ), each filter housing ( 110 ) having a top ( 111 ) and a bottom ( 112 ); (b) a lower reservoir ( 150 ) fluidly connected to the first filter housing ( 110 a ) via a first drain pipe ( 120 a ), the first drain pipe ( 120 a ) allows water from the first filter housing 110 a to drain into the lower reservoir ( 150 ), the lower reservoir ( 150 ) functions to allow contaminants in the water to collect on a bottom surface, wherein the lower reservoir ( 150 ) is divided into a first half reservoir and second half reservoir, the first half reservoir being fluidly connected to the second half reservoir via a connection pipe ( 170 ), wherein a sectional wall ( 154 ) is disposed in the first half reservoir to separate the rust that came from the emissions/soot via the drain pipe ( 120 a ); (c) a second drain pipe ( 120 b ) fluidly connected to lower reservoir ( 150 ) via a pump ( 220 ), the pump ( 220 ) functions to pump water from the lower reservoir into the third filter housing ( 110 c ); and (d) a third drain pipe ( 120 c ) is fluidly connected to the lower reservoir ( 150 ), the third drain pipe ( 120 c ) functions to allow the contaminants collected at the bottom surface of the lower reservoir ( 150 ) to be drained; wherein a filter cover ( 310 ) is disposed in each filter housing ( 110 ) at the bottom ( 112 ) and a filter ( 320 ) is disposed in the filter cover ( 310 ) and a soaking cone ( 330 ) is disposed in the filter ( 320 ); wherein the second drain pipe ( 120 b ) is fluidly connected to a sprayer system ( 350 ) disposed at the top ( 111 ) of the third filter housing ( 110 c ) above the soaking cone ( 330 ), the sprayer system ( 350 ) functions to spray the water pumped from the reservoir ( 150 via the pump ( 220 ) into the top ( 111 ) of the third filter housing ( 110 c ); wherein the water drains from the third filter housing ( 110 c ) to the first filter housing ( 110 a ) and further back to the lower reservoir ( 150 ) via the first drain pipe ( 120 a ).
