1. a kind of method that particle is stripped from particle-fluid suspended object, it includes:

  • Particulate fluid-the suspended matter is introduced into container, which includes two or more along common longitudinal centerThe coaxially arranged interior zone of line, wherein first area have the first cross-sectional area and second area is conical butt;

    Selective Separation particulate fluid-suspended matter in the first region, come provide flow in a first direction substantially withoutThe fluid section of particle and the substantially fluid free particle fraction flowed in a second direction, wherein substantially without particleThe solid concentration of fluid section is less than 5%wt solids;

    The substantially fluid free particle fraction is deposited in second area, to provide the micro- of one or more sedimentations whereinGrain;

    One or more stripping fluids are supplied from external fluid source of supply;

    One or more stripping fluids are introduced into the assignment channel being arranged in around second area;

    By one or more stripping fluids via multiple fluid lines, flowed to from the assignment channel and be arranged in restriction second areaWall outer surface on multiple holes in;

    WithOne or more stripping fluids are flowed upwardly through into second area using the hole, it, should to form fluid bed whereinParticle of the bed comprising one or more stripping fluids and one or more sedimentations,Wherein, 95%wt or higher any particle are withdrawn from second area in particulate fluid-suspended matter.
