Abstract
A filtration apparatus comprises a casing defining an inner cavity with an upper cylindrical portion and a lower hopper portion. An inlet feeds gas and solids into the inner cavity and causes movement of the solids in a downward spiral path in the casing. A solids outlet at a bottom of the lower hopper portion outlets the solids from the casing. A gas outlet exhausts gases from the casing. An annular arrangement of ports in a wall of the casing injects an other gas in the inner cavity. The ports are oriented to guide the other gas into following a partially vertical path into the inner cavity to disrupt the movement of the solids in the downward spiral path to allow a capture of the solid particles by the capturing solids. A gas source is connected to the arrangement of ports.
Claims12
A filtration apparatus for filtering solid particles from a gas, with capturing solids, comprising:
- a casing defining an inner cavity with an upper cylindrical portion, and a lower hopper portion connected to the upper cylindrical portion;
- at least one inlet in the upper cylindrical portion for feeding a flow of gas and solids into the inner cavity, the at least one inlet being positioned with respect to the casing to cause movement of the solids in a downward spiral path in the casing;
- a solids outlet at a bottom of the lower hopper portion for outletting the solids from the casing by gravity;
- a gas outlet in the upper cylindrical portion to exhaust gases from the casing;
- an annular arrangement of ports in a wall of the casing to inject an other gas into the inner cavity, the ports being oriented so as to guide the other gas into following a path at least partially vertical when entering the inner cavity to disrupt the movement of the solids in the downward spiral path to allow a capture of the solid particles by the capturing solids;
- an annular casing on an outer periphery of the casing opposite the ports, the annular casing concurrently forming with the outer periphery of the casing an annular cavity in fluid communication with the annular arrangement of the ports in the wall of the casing, the annular cavity being delimited radially outwardly by the annular casing and radially inwardly by the outer periphery of the casing;
- and
- a gas source connected to the annular casing for the injection of the other gas into the inner cavity via the annular cavity.
