Maintaining the stability of the fluidized bed ensures stable operation of the magnetically stabilized fluidized bed

The design of the fluidized bed body increases the bed diameter D, which not only reduces the wall effect of the velocity distribution, but also makes the airflow velocity distribution in the bed more uniform, and can increase the ability to process dusty gas per unit time. In this design, the diameter D of the bed is 0.5m, the cross-sectional area of ​​the empty bed is about 0.2m2, and the apparent flow rate of the gas is 3m/s, so the capacity of treating the dust-containing gas per hour is higher than 2000m3 (standard cubic meters). The device has certain practical application value. Improve the design of the air distribution panel, which consists of a flower panel and a hood. In order to avoid interference with the magnetic field in the bed, the flower plate is made of 8 mm thick copper plate, the copper hood on the flower plate is arranged in an equilateral triangle, and the hood adopts a tapered side hole structure. The air distribution plate of the structure can generate a certain resistance to the airflow flowing through the air distribution plate, not only obtain a uniform airflow velocity distribution on the air distribution plate, but also improve the fluidization quality of the gas-solid two-phase in the bed, and can avoid the cause Dust accumulation leads to blockage of the inlet duct, maintaining the stability of the fluidized bed and ensuring stable operation of the magnetically stabilized fluidized bed.

The design of the particle regenerator is due to the continuous accumulation of dust in the bed. The magnetic particles in the bed will weaken the dust collection. Therefore, the particles in the bed need to be updated to achieve efficient and continuous operation of the dust removal device. . To this end, a dedicated particle regenerator has been designed. The main part is a mechanical vibrating screen. In view of the fact that the magnetic particles in the bed are in a fluidized state and have good fluid properties, a small amount of particles in the bed can be taken out and sent to the vibrating screen, and the particles adhering to the dust are continuously vibrated, the dust is peeled off, and the dust falls to the gray warehouse. The cleaned particles are sent back to the bed via compressed air for regeneration. The regeneration rate of the magnetic particles is determined by the concentration of the dust contained in the inlet and the amount of gas processed per unit time. (Finish)
