Definitions

  • a cyclone separator including a porous wall forming a primary conically shaped chamber, a pipe for directing fluid having foreign particles therein tangentially into the larger end of the primary chamber to provide a vortical whirl, a clean-fluid outlet within the chamber between the inlet pipe and the smaller end of the primary chamher, a water jacket and a liquid inlet around the porous wall to force liquid therethrough and into the primary chamber and a conically shaped extension forming a secondary chamber connected to the smaller end of the pr mary chamber.
  • the diameter of the primary chamber 18 smaller than the diameter of the secondary chamber at the junction of the two chambers.
  • This invention relates to a centrifugal separator for separating solids from a liquid suspension.
  • Centrifugal separators are generally used in the punfying of a liquid or a gas by the removal of particles entrained therein.
  • An important field of use for centrifugal separators is in the purifying of paper stock where in wood pulp fibers are suspended in the water solution, an example of this type of general application of the centrifugal separator is shown in US. Patent 2,377,524, Sampson et al. It will be understood that the principles of the present invention will find application in many fields but for convenience of disclosure of preferred embodiments thereof reference will be made to the use of a centrifugal separator for purifying paper stock.
  • the carrier fluid and the particles are to be classified into categories as follows:
  • centrifugal component among other forces acting on the entering stream.
  • This component is a function of the tangential velocity and the radius of the particular point and its action will immediately separate the c-3 fraction referred to above. This fraction will remain, during the interval of time present in the cone, in a helical path close to the wall until it is discharged at the apex of the cone.
  • the other force acting on the flow is the entrainment of the liquid created by the presence of central discharge orifice.
  • the intensity of this field depends on the size of this orifice, and it increases with decreasing of the orifice. (It is clear, then, that two units capable of identical discharge flows, pressure drop, geometric configuration, etc., the one which has a smaller discharge orifice will be superior in its final performance.)
  • the probability that a particle, which passes through this field, will be accepted is extremely high since the retention time is extremely low.
  • fresh liquid is introduced through the Wall of the cone.
  • the slowly difiusing liquid from the porous wall cleaner liberates the b fraction and entrains the same toward the center of the unit Where it will have again a chance to be accepted.
  • the early introduction of the liquid through the porous wall increases, therefore, the number of chances the particles have to be selected since the flow continuously entrains also the dubious particles contained in the fraction c-l and 0-2 close to the periphery, toward the central discharge opening.
  • the liquid layer provided through the porous wall has, therefore, two possible exits:
  • a fu ther object of the invention is provided in an improved cyclone cleancr wherein a liquid layer is introduced throu h the porous outer wall cleaner for improved effects on the objectionable action of material which is to be separated from the acceptable fraction within the cleaner to obtain a more effective and elficient cleaning operation.
  • Yet another object of the invention is the reduction of the concentration of fiber at the wall of a conical separator and thereby providing a separator capable of efficiently handling suspensions having high or low consistencres.
  • FIGURE 1 is a longitudinal sectional view of the centrifugal separator in accordance with the invention.
  • FIGURE 2 is a detailed sectional view of a portion of the centrifugal separator shown in FIGURE 1.
  • the water suspension and solid impurities are forced into the tangential input so that a vortical whirl is created along the inside wall of the conical primary chamber.
  • Input flow may be controlled by a valve 11.
  • the heavier solid particles move toward the tip 39 forming a secondary chamber and the liquid suspension, which is effected by centrifugal force to a lesser extent, is returned within the vertex of the vortical whirl to the outlet 4%.
  • the water slowly diffuses inwardly through the porous wall and entrains the acceptable fraction of the paper pulp suspension toward the center of the vortrcal whirl.
  • the rejectable particles which have not yet been removed from the suspension are also entrained so that the number of chances that have to be selected and removed is increased thereby increasing the effectiveness of the cleaning action of the cleaner.
  • the cross-sectional area of the vortical whirl is less than the cross-sectional area of the conical chamber within the chamber due to the concentration effect.
  • the effective diameter d of tip-section is greater than the diameter D of the cross-section of the porous wall 20. This enables the heavier particles to travel in a longer path which tends to keep these particles away from the central upwardly movin g vortex.
  • the apex of the tip-section 36 can also have a relatively smaller dimension, because the efiiciency of the centrifugal separator is correspondingly increased in accordance with a feature of this invention.
  • the size of the discharge orifice of a centrifugal separator is controlled by the efficiency of the separator because dilution at the boundary of the wall of the chamber causes the desirable wood pulp or fibers to move radially toward the center of the vortical whirl and thence to the outlet 40 so that the suspension at the outlet has a greater percentage of desired particles.
  • a separator due to the high consistency of the concentrated fibrous pulp at the apex outlet, must have an opening of a certain size to avoid clogging of the pulp in the outlet. This means that at higher consistency, due to a high tendency for clogging, the apex opening must be relatively larger. The increase in size of the opening is coupled with large reject flows and, therefore, lower efiiciencies due to the loss of desired fibrous pulp.
  • FIGURE 2 is a more detailed view of a portion of the porous wall 20 and a portion of the tip-section 30. It can be readily noted that a discontinuity exists between the inside of the Wall 20 and the inside of the tip-section 30 at the point at which the wall 29 joins the tip-section 30. The sudden enlargement lengthens the path of the particles thereby tending to keep the reject particles away from the central vortex so that reject particles are discouraged from becoming entrained in the upwardly moving vortex.
  • the water passing through the porous walls 29 causes the desired lighter particles to move radially toward the center of the vortex and thence become entrained in the upwardly moving central vortex; whereas, the larger tip-section 3% tends to keep the heavier undesirable particles way from the upwardly moving vortex and to continue on in a downward direction toward the apex orifice.
  • the invention involves the method and apparatus of cleaning a paper pulp suspension of foreign particles by passing the suspension into a conically shaped cyclone chamber provided with a layer oi fresh water on the wall and having a tip with the non-porous wall at the smaller end, having an opening for the removal of foreign particles.
  • the tip has a diameter less than the smaller end of the chamber by an amount equal to the layers of water on the inner wall of the chamber.
  • This arrangement permits a decrease in outlet orifice size with increased efficiency.
  • the size of this orifice controls the eificiency and a smaller size is important.
  • By decreasing the outlet orifice an increase in angular velocity is achieved. It has been found that the size of the inlet orifice can be reduced with the same pressure differential it the shell surface is lubricated as is provided in accordance with the present invention. Also, with the same pressure differential, an increase in volume can be achieved.
  • spar rat 6 I claim as my invention: directing a flow of pressurized fresh water radially into 1.
  • An elongated cyclone separator for removing from the conical path to mix with the suspension and to a fluid foreign particles suspended therein comprising, urge lighter particles toward the center of the vortex,
