Pollution-free tube-bundle separation-type permanent-magnet separating device being suitable for separating superfine magnetic particles

Abstract

The invention relates to a pollution-free tube-bundle separation-type permanent-magnet separating device being suitable for separating superfine magnetic particles, which comprises a permanent-magnet magnetic field and a separating room, wherein a plurality of separating tubes are installed inside the separating room, and magnetic conduction media such as threadlike steel wool or steel emery are installed at the outer side of each separating tube. An annular permanent magnet is fixed on a rotating shaft at the outer side of the separating room. A C-shaped permanent magnet is adopted to produce high magnetic density and gradient, the magnetic field is applied to the periphery of the tube bundle through the filled magnetic conduction substances, and the fluid is separated from the magnetic conduction substances through the separating tubes so as to prevent the fluid from corroding and polluting the steel wool and the like. The device has a simple structure, is convenient to operate, is suitable for separating the magnetic carrier or catalyst from the fluid, and is particularly suitable for separating the weak magnetic superfine particles in the fluid.

Description

technical field [0001] The invention relates to a device for separating magnetic particles in a fluid, which is mainly used in the fields of catalysis, adsorption and biological separation, and in particular to a non-polluting tube bundle isolation permanent magnetic separation device suitable for ultrafine magnetic particle separation. Background technique [0002] Magnetic separation technology is not only widely used in the sewage treatment of mineral processing, steel mills and power plants, but also for the selective separation of particle systems in the coal industry, non-metallic industry, petroleum industry, atomic energy industry, chemical industry and biotechnology. An effective solution is provided. [0003] The ultrafine magnetic carrier particles commonly used in magnetic separation technology have advantages that ordinary solid particles do not have: ultrafine particles have a large specific surface area, and can greatly speed up the reaction speed when perform...
