[0002] Magnetic filters are mainly used in petroleum, chemical industry, metallurgy, medicine, machinery, automobile and other fields to remove a large amount of iron filings, iron powder and other ferromagnetic impurities contained in various liquids, slurries and gases, and can be used for precious metal catalysts Recovery and clarification of weak magnetic medium, etc. With the rapid development of petrochemical industry, including emerging coal chemical industry, metallurgy, automobile industry and the strengthening of environmental protection, especially for the hydrogenation reaction of polyaromatic hydrocarbons in coal chemical industry; high catalytic activity Raney nickel catalyst The requirement for recycling is becoming more and more urgent. The permanent magnet separation made of traditional rare earth materials is limited by the inherent magnetic field strength and cannot be adjusted, the uniformity of the magnetic field distribution is poor, and the efficiency of filtration and separation is not high. In terms of separation effect and application range There are many limitations in the field and field. At present, the magnetic filter mainly uses permanent magnets as the filter core to remove ferromagnetic particles in the medium. However, due to the uneven distribution of the magnetic field of the permanent magnets, the filtration efficiency is not high, and the magnetic energy consumed by the electromagnetic coil It is easy to burn out when the temperature is high, the maintenance and replacement process is complicated and troublesome, and it is difficult to meet the application occasions with certain precision requirements; in addition, the magnetic filter mainly uses water as the backwash medium in the process of backwashing, and the backwashing efficiency is low. consumes a lot

[0003] Most of the electromagnetic separation devices or systems at home and abroad are used in the magnetic separation of lean iron ore. Compared with such products, the innovative structural design of the product of this project makes the uniformity of the magnetic field better and the gradient distribution under the same magnetic field strength. More reasonable; the temperature and corrosion resistance of the filter element is more prominent; the specially designed structure can use the gas-liquid backwashing process to realize the efficient cleaning of the filter residue; the automatic temperature control device is used to control the temperature rise of the electromagnetic coil. Under the changes of temperature, pressure, vibration, liquid flow and speed, the magnetic filter responds slowly and cannot keep up with the requirements of actual working conditions
