Patent ID: 7938872

Claim:
Separating device for separating particles ( 4 ) from a gas stream ( 2 ) in which the gas stream ( 2 ) by means of a guiding device is caused to rotate and the liquid or solid particles ( 4 ) to be separated are removable by a particle outlet, wherein the separating device ( 1 ) comprises: a housing pipe ( 5 ) with a guiding device ( 3 ) and an immersion pipe ( 6 ) arranged in alignment with the flow direction of the gas stream ( 2 ) in the housing pipe ( 5 ), wherein the immersion pipe is provided on the exterior with a spiral ( 7 ) for a directed removal of the particles ( 4 ) separated by rotation to a housing opening ( 8 ) as a particle outlet, wherein the spiral ( 7 ) is formed on an upstream facing face of a cylindrical wall portion of said immersion pipe ( 6 ), said cylindrical wall portion received into and abutting an interior wall of said housing pipe ( 5 ), wherein a conically inwardly tapered end of said immersion pipe has a central outlet ( 9 ) for discharge of the purified gas stream ( 2 ) through an interior passage of said immersion pipe, wherein said immersion pipe ( 6 ) between with the spiral ( 7 ) and said central outlet ( 9 ) tapers conically inwardly and projects into the housing pipe ( 5 ), a conically tapered end of said immersion pipe ( 6 ) having a central outlet ( 9 ) for the purified gas stream ( 2 ).
