Abstract
A particulate extraction system is disclosed, which passively removes particulates and some acids from a flue gas by forcing a series of volume and/or temperature changes on the flue gas. The system may have an interconnected series of chambers of varying cross-sectional sizes to effect the changes in volume. The system may also be uninsulated to allow the flue gas to be cooled as by radiation.
Claims12
A particulate extraction apparatus for removing contaminants from a flue gas flowing in a direction from upstream to downstream, the apparatus comprising:
- a plurality of chambers, each chamber having an inlet port, an outlet port, and at least one adjacent chamber, a first selected chamber being designated as an initial chamber to receive the flow of flue gas, a second selected chamber being designated as a final chamber to exhaust the flow of flue gas from the plurality of chambers, the chambers arranged in an ordered sequence with the initial chamber upstream from all other chambers and the final chamber downstream from all other chambers, the outlet of each chamber that is not the final chamber being in communication with the inlet of an adjacent downstream chamber.
A particulate extraction apparatus for removing contaminants from a flue gas, the apparatus comprising:
- one or more sections stacked vertically, each section containing a leftmost chamber and a rightmost chamber that do not communicate with each other, each chamber in the section having a top side, a bottom side, a port in the top side, and a port in the bottom side, the uppermost section receiving a stream of flue gas through the top side port of the leftmost chamber, the uppermost section delivering the stream of flue gas out of the top side port of the rightmost chamber;
- and
- a containment vessel supporting the stacked sections with the bottom sides of the chambers in the lowest section in direct contact with a containment vessel top side, the containment vessel top side having a first containment vessel port in communication with the bottom side port of the leftmost chamber of the lowest section, the containment vessel top side having a second containment vessel port in communication with the bottom side port of the rightmost chamber of the lowest section;
- wherein the apparatus conducts downwardly the stream of flue gas entering the top side port of the leftmost chamber of the upper section through all the leftmost chambers sequentially until the stream enters the containment vessel, horizontally from the first containment vessel port to the second containment vessel port, and thence upwardly through the rightmost chambers of each section sequentially to exit through the top side port of the rightmost chamber in the uppermost section.
