Magnetic separation, method and apparatus

摘要

An apparatus and a method are described for separating magnetizable particles from a fluid in which they are suspended. The apparatus comprises a separating chamber having an inlet and an outlet for permitting fluid to enter and leave the separating chamber, a matrix of a plurality of ferromagnetic filaments arranged substantially parallel to one another and to the general direction of flow of fluid through the matrix and disposed in the separating chamber, magnet means for establishing a high intensity magnetic field in the separating chamber perpendicular to the general direction of flow of the fluid through the matrix, and removal means for removing magnetizable particles attracted to the matrix within the separating chamber. The method comprises establishing a high intensity magnetic field in a matrix of a plurality of ferromagnetic filaments arranged substantially parallel to one another and perpendicular to the direction of the magnetic field and passing fluid containing magnetizable particles through the matrix generally in the direction of alignment of the filaments and removing magnetizable particles retained on the matrix.
