Problems solved by technology
However, loaded magnetic porous media are not charged, so this technique cannot be used to separate
Moreover, charge separation requires rapping, which will cause secondary dust, and the capture of occasions containing a large amount of magnetic porous media is far from meeting the standard; in addition, the entire dust removal device requires high-voltage power transformation and rectification equipment, investment and operation The cost is higher

The invention relates to a device for recovering magnetic particles in gas by a rotating magnetic field, belonging to the field of gas-solid separation. A device for recovering magnetic particles in gas by a rotating magnetic field, the device comprising: a gas-solid separation channel; an air intake channel, the connection surface of the air intake channel and the gas-solid separation channel near the ground is a curved connection surface; the rotating magnetic field Generating device, the rotating magnetic field generating device is arranged below the air intake channel and close to the curved connection surface; the rotating magnetic field generating device includes a columnar rotating shaft, a plurality of electromagnets uniformly arranged on the surface of the rotating shaft along the circumference, for controlling the rotation Power unit and control unit for shafts, power unit for controlling electromagnets. The use of the electromagnet of the device of the present invention can prevent the magnetic medium after being adsorbed from being blocked in the flue, especially at the corner. Through the use of multi-lobed discs, especially when non-magnetic lobes are interposed between the individual lobes, the transfer collection process of the medium can be better controlled.
Description
technical field [0001] The invention relates to a device for recovering magnetic particles in gas by a rotating magnetic field, belonging to the field of gas-solid separation. Background technique [0002] Separation technology and magnetic separator have a development history of more than 50 years. With the help of magnetic field force, it can separate substances with different magnetic permeability, and it was first used in the mineral processing industry. After the invention of the industrial magnetic separator in the United States, magnetic separation began to be applied on a large scale in the form of mechanical equipment in fields other than coal desulfurization, iron removal from raw materials such as glass and cement, and kaolin purification. In recent years, the magnetic separation method is mostly used in the water treatment industry. The magnetic separation uses the magnetism of the impurity particles in the wastewater to separate. For the non-magnetic or weakly m...
