Problems solved by technology

They are only used for reaction or separation alone, which brings a lot of trouble to the operation, and the magnetic field used is usually an electromagnetic field, the magnetic field strength is weak, and the equipment cost is high; the integration of reaction and separation is conducive to scaling up and reducing operating costs. It is one of the important directions of chemical industry development at present; there is no report on the integration of ultrafine magnetic particles for reaction and continuous separation

Embodiment

[0043] When magnets a, c, f, h are close to the surface of the reactor, magnets b, d, e, g leave the surface of the reactor, and the magnetic particles gather at the corresponding positions where magnets a, c, f, h are close to the wall of the reactor ; When magnets a, c, f, h leave the surface of the reactor, magnets b, d, e, g are close to the surface of the reactor. b, d, e, and g are gathered at the positions close to the reactor surface, such continuous reciprocating motion makes the magnetic particles form a wave motion in the rectangular reactor surface, refer to Figure 2 and image 3 . Therefore, the magnetic particles form a wave motion in the device and achieve the effect of stirring and dispersing. There is a certain residence time, and physical and chemical reactions can be carried out. Under the action of the magnetic field force on the rotating rollers 2 and 8 (the two shafts on the rotating rollers 2 and 8 drive the semicircular magnetic rings on it to rotate i...

Abstract

The integral catalyst reaction and continuous separation apparatus includes inclined cuboid reactor of magnetic conducting material; two magnet combinations near the upper and lower surfaces of the reactor separately and with magnets capable of moving up and down; feeder connected to the upper end of the reactor and discharge pipe connected to the discharge port in the lower end of the reactor and with one baffle suspended over the discharge pipe; granular regenerator connected between the discharge pipe and the feeder; and two rotating rollers with opposite rotation directions and with annular magnetic roller comprising two hemi-ring magnets installed. Inside the apparatus, superfine magnetic grains can form wave motion to reach stirring effect for simultaneous reaction and separation.

Description

technical field [0001] The invention relates to a device for the reaction and separation of magnetic particles in liquid / gas phase fluids, which is mainly used in the fields of catalysis, adsorption and biological separation, and in particular to an integration of ultrafine magnetic particles in fluids for catalytic reaction and continuous separation device. Background technique [0002] Ultrafine magnetic particles have the advantages that ordinary solid particles do not have: ultrafine particles have a large specific surface area, which can greatly speed up the reaction speed when performing physical and chemical reactions; in addition, particles with superparamagnetic characteristics Under certain conditions, the particles exhibit good magnetism. When the external magnetic field is removed, the remanence of the particles is zero. According to this characteristic, the superparamagnetic particles can be conveniently located, separated, and recover...
