Fluidized electric separation device

Abstract

The invention discloses a fluidized electric separation device which comprises a fluidized electric separation device body, a high-pressure power supply and an air supply system. An air chamber of the fluidized electric separation device body is connected with the air supply system through a pipe. The fluidized electric separation device body comprises a fluidized bed, an air distributor, the air chamber, a feeding inlet and a discharging outlet. The feeding inlet and the discharging outlet are formed in the two ends of the fluidized bed respectively. A material distribution plate is arranged in the discharging outlet in the horizontal direction. Electrode plates are arranged on the inner walls of the two sides of the fluidized bed. the inner sides of the two electrode plates or the inner side of one electrode plate are / is exposed or provided with an insulating partition, and the electrode plates are connected with the positive pole and the negative pole of the high-voltage power supply respectively; or one side of each electrode plate is connected with the power supply, and the other side of each electrode plate is connected with the ground. A friction bar set is arranged in the fluidized bed in the axial direction. Powder material is in full friction with friction bars in the fluidized bed and the electrode plates or the insulating partition to be fully charged, or the powder material is in conduction sensing with the friction bars in the fluidized bed and the electrode plates or the insulating partition to be fully charged. The electric charging requirement in the separation process is met, the material charging effect is good, separation efficiency is high, the process is simple, energy consumption is low, and the device is simple.

Description

technical field [0001] The invention belongs to the technical field of dry separation of solid materials, and in particular relates to a fluidized electric separation device. Background technique [0002] Powder is a solid in a special form, and the generation of static electricity conforms to the basic principle of a double electric layer. During the frictional electrification process of powder, there is also a process in which the charge is released through the wall of the device, the wall of the pipe, the tooling, the equipment and even the atmosphere. [0003] There are many factors that affect the static electricity generated by powder materials in the process of motion friction, such as the properties of powder materials, including their chemical composition, particle size, deformation state, and surface geometric characteristics; chemical structure, conductivity of the wall material in contact with the material; contact The size of the surface, the contact time, the ...
