Abstract
A separator for separating solid particles from a hot gas stream comprises a cyclone chamber having an axial gas outlet conduit. The outlet conduit is formed by a plurality of cooling tubes defining between the tubes a plurality of passages for the gas. The outlet conduit is connected to an opening in one or both ends of the cyclone chamber. Solids are separated by centrifugal forces as the gas flows in a curved path in the cyclone chamber and by inertia forces as the gas changes direction to flow into the outlet conduit.
Claims21
A paritcle separator for separating solids and gases in a hot gas stream having solids entrained therein comprising:
- a cyclone chamber having an axis and means for guiding the hot gas stream with entrained solids about an axis;
- an inlet duct in communcation with said cyclone chamber for introducing the stream into said cyclone chamber;
- at least one outlet for said cyclone chamber for removing solids separated from the stream in the cyclone chamber;
- and
- a conduit disposed in said cyclone chamber extending generally in an axial direction and having a gas outlet, said conduit being formed by a plurality of tubes extending generally in said axial direction with said tubes adapted to receive a coolant, said tubes defining a plurality of slots therebetween providing for passage of the gas from the cyclone chamber into said conduit and through said gas outlet.
A particle separator according to claim 2 wherein said tubes are arranged to change the direction of flow of the gas flowing from said cyclone chamber through said slots into said conduit.
A particle separator for separating solids and gas in a hot gas stream having solids entrained therein comprising:
- a cyclone chamber having an axis and means for guiding the stream of hot gases with entrained solids about an axis;
- an inlet duct in communication with said cyclone chamber for introducing the stream into said cyclone chamber;
- at least one outlet from said cyclone chamber for removing the solids separated from the stream in the cyclone chamber;
- and
- means defining a conduit disposed in said cyclone chamber and having a gas outlet, said conduit means having a plurality of passages adapted to receive a coolant, said conduit means having a plurality of openings providing for passage of the gas from the cyclone chamber into said conduit in heat exchange relation with said plural passages whereby cooled gases flow through said gas outlet.
A method for separating solids and gases in a stream of hot gases and solids entrained in said hot gases comprising the steps of:
- guiding the stream in a cyclone chamber for flow about an axis to separate the solids and the gases in the stream;
- and
- diverting the flow of gases through a plurality of slots formed by tubes constituting a conduit extending generally in said axial direction;
- flowing a coolant through said tubes.
