Definitions

  • Method of increasing the separating action of a vortex separator for solid or liquid particles entrained in a gaseous carrier medium includes supplying particleentrained gaseous carrier medium in an axial direction and in the form of a rotational flow through an inlet located at one end of a rotationally symmetrical vortex chamber; surrounding the rotational flow with a tubularshaped vortex of a gaseous auxiliary medium coaxial with and rotating in the same rotary direction as the rotational flow; discharging the carrier medium through an outlet provided in the other end of the vortex chamber; transforming the tubular-shaped vortex at the outlet of the carrier medium into the circulatory potential flow traveling at a region adjacent the wall of the vortex chamber in a direction opposite to the axial flow direction of the carrier medium and back again at the level of the carrier medium inlet into the tubular-shaped vortex surrounding the rotation flow, so that the auxiliary medium travels in a closed circuit; removing by suction the auxiliary medium in the tubular-shaped vortex flowing

  • a potential circulatory flow is excited and maintained adjacent the walls of a rotationally symmetrical vortex chamber in such a Way that it undergoes a movement in the axial direction of the vortex chamber in addition to the circulatory movement, that axial movement being opposite to the aerosol or dust-laden gas flow flowing axially into one end of the vortex chamber.
  • a component of this potential circulatory flow is diverted toward the axis of the vortex chamber at the level of the aerosol inlet and is transformed together with the aerosol into a co-axial rotational flow circulating in the same direction as the potential circulatory flow within the potential circulatory flow.
  • the particles that are to be separated are passed radially out of the rotational flow, due to the rotation, and into a branch of the potential circulatory flow delivering them into a particle outlet surrounding the aerosol, and from there into a storage chamber, while the purified aerosol discharges from the vortex chamber through a purified-gas outlet at the other end of the vortex chamber.
  • the potential circulatory flow is produced by the additional supply of a gaseous auxiliary medium which is admitted so that it joins the aerosol flow at an acute angle to the axis of the aerosol flow and in a generally tangential direction to the wall of the vortex chamber.
  • one end of a rotationally symmetrical vortex chamber an aerosol or particle-laden gas flow admitted in an axial direction in the form of a rotational flow is surrounded by a coaxial tubular-shaped vortex or vortex tube of an auxiliary gaseous medium circulating in the same direction as that of the rotational flow as well as moving in the same axial direction.
  • a coaxial tubular-shaped vortex or vortex tube of an auxiliary gaseous medium circulating in the same direction as that of the rotational flow as well as moving in the same axial direction.
  • the auxiliary gaseous medium with the potential flow circulating in a travel direction opposite to that of the aerosol fiow and at the level of the aerosol inlet once again is transformed into the vortex tube circulating with the rotational flow in such a way that the auxiliary medium is guided in a substantially closed circuit.
  • a closed circuit of the auxiliary medium can be effected by applying suction to the auxiliary medium flowing coaxially to the aerosol in the form of a vortex tube at the level of the outlet for the purified aerosol and through an annular slot or aperture in the upper portion of the vortex chamber of the separator, an auxiliary medium is newly resupplied thereto.
  • the removal of the auxiliary medium by suction and reintroduction thereof by blowing is effected, in accordance with a further feature of our invention, by an intermediately located blower means.
  • the auxiliary medium forming the outer potential circulatory flow is removed at the level of the aerosol inlet and is newly resupplied coaxially to the aerosol inlet, both by means of suction.
  • FIG. 1 is a diagrammatic view of a theoretical vortex separator constructed in accordance with the invention
  • FIG. 2 is a diagrammatic view of a first practical embodiment of the invention wherein the removal and resupply of the auxiliary medium by suction is eifected at the outlet end of the vortex separator;
  • FIG. 3 is a diagrammatic view of another embodiment of the vortex separator according to the invention wherein suction removal and resupply of the auxiliary medium is effected at the level of the aerosol inlet;
  • FIG. 4 is a diagrammatic view of yet another embodiment of the vortex separator according to the invention wherein a portion of the auxiliary medium is supplied through nozzles located tangential to the walls of the vortex chamber and at an acute angle to the axis of the aerosol flow.
  • the solid or liquid aerosol flows into a vortex chamber 1 through an inlet 2 in the direction of the arrows 4 and is excited for example by means of a pre-twist nozzle 3, provided with suitable vanes in a conventional manner, to form a rotational flow 5 in the direction of the associated arrowheads.
  • This inner coaxial rotational flow 5 is surrounded by a tubular-shaped vortex or vortex tube 8 of a gaseous auxiliary medium.
  • This vortex tube 8 flows, as indicated by the associated arrowheads, in the same direction as the rotational flow 5 through the vortex separator and forms therewith the radially outer limiting region of the rotational flow 5.
  • the auxiliary medium after being diverted at the level of the aerosol outlet 6, flows in the form, substantially, of a potential circulating flow 9 in a direction opposite to the travel direction of the aerosol toward the aerosol inlet 12, and at the aerosol inlet is again diverted to the rotational flow 8.
  • the path of the auxiliary medium flowing in the circuit is thereby indicated by the reference numeral 10.
  • the gaseous layer surrounding the aerosol flow 5 thus constitutes a voretx tube with respect to the axial velocity thereof, the axial velocity of the vortex tube portion which is adjacent the aerosol being in the same travel direction as that of the aerosol flow whereas the axial velocity of the portion of the vortex tube located directly at the stationary wall 1 of the vortex chamber has a direction opposite to that of the aerosol flow.
  • the particles ejected from the main gas flow or aerosol thus pass into the circulating flow 10' of the auxiliary medium and become concentrated therein.
  • the particles are discharged substantially at the reversal point of the potential to rotational flow by a branch of the potential circulatory flow into a collecting chamber 11 surrounding the aerosol inlet 2.
  • FIG. 2 there is shown means for removing the auxiliary medium by suction atthe level of the aerosol outlet 6.
  • the auxiliary medium is evacuated through an annular slot or aperture 15 of the vortex separator 1 and is resupplied by means of a blower 16 through an annular slot or aperture 17. Energy lost due to friction of the auxiliary medium in the vortex separator is replaced by the blower 16.
  • Pro-twisting of the auxiliary medium when readmitted into the vortex chamber is efiected by means of guide vanes or nozzles 13 in the annular slot 17, for supplying the readmitted auxiliary medium in such a way that it joins the aerosol flow in a generally tangential direction and at an acute angle to the axis of the aerosol flow.
  • the annular slot 17, itself can have a nozzle-like construction.
  • the removal by suction of the auxiliary medium is eifected by an annular slot 18 in the wall of the vortex chamber at the level of the aerosol inlet 2.
  • a blower 16 which serves for restoring the frictional losses in the vortex chamber, the auxiliary medium is resupplied to the vortex separator through a coaxial annular slot 19 provided in a tubular member directly connected to the aerosol inlet tube 2.
  • suitable conducting vanes or nozzles 13 can be located in the annular slot 19 to provide pre-twisting of the readmitted auxiliary flow medium.
  • a portion of the auxiliary medium removed by suction through the outlet 18 is readmitted through the nozzles 20 joining the aerosol flow in a generally tangential direction and at an acute angle to the axis of the aerosol flow for exciting the potential circulatory flow in the vortex separator.
  • the aforedescribed turbulence and scaling phenomena adjacent the wall of the vortex chamber are prevented from spreading into the aerosol flow so far as the auxiliary medium, with respect to its rotation, has a greater energy than the aerosol.
  • the auxiliary medium due to the circulatory motion, exhibits no throughput or flow-through, the entire energy content thereof does not enter into the required energy consumption for the aerosol flow proper, but rather, only the energy losses of the auxiliary medium. Consequently, with the instant invention it is possible to provide efliciently an essentially greater rotation of the aerosol flow than is posible, for example, in a conventional cyclone separator.
