Cycloneair Flow Field Simulation And Particle Characteristics (Pm10.0, Pm2.5) Analysis
Journal Title: PARIPEX-Indian Journal of Research - Year 2015, Vol 4, Issue 5
Abstract
In real life, a good mathematical model calculations and with the appropriate simulation equations by computer fast computing power, its accuracy is pretty amazing. The development of modern science and engineering, all the innovation and invention, were intended to improve the living standards of our humanity. Since we could not avoid the dust generated in the environment, the dust collector was the life of a very important tool for dusting. How to improve this little helper, increasing further enhance the efficiency of the dust collector,was the main objective of this study.This research were bothexploratory and confirmatory studies at the same time.This study simulated cyclone air flow field, mining groups A and B to do experimental design Two experimental groups the biggest difference were that the way was the wind A group tangentially into the annular inner dust collector. Group B was the way into the wind, a non-tangential direction into the ring inside of dust collector. Respectively, inlet position of both groups(A and B) were with low, medium and high into the air to do different trials comparing. CFD software package was a powerful computing capabilities. its dynamic equations of fluid mechanics, was a self to do know how rational, logical judgment of engineering objects. After each group different attempt,simulation results showed that: (1) the way of the wind cut flush to the surface, regardless of the position in the low, which medium or high position, the resulting vortex, were smooth on the way of the wind cut flush to the surface in a non-person. (2) the way of the wind did not cut flush to the surface, regardless of the position in the low, which medium or high position, vortex generated by all the way of the wind into the ring true to cut flush to the surface of those. (3) at a fixed speed, the less were rotating scroll smoothly, the lessthe amounts of dust falling. The more vortex rotations were not smooth, the more the amounts of dust falling.After the actual operation of large cyclone separation, under the electron microscope SEM could be found that: (4) SiCparticleswerescreened to Separate out different sizes. (5)For further,This study analyzedthe changes betweenPM10.0 and PM2.5 particle. Conclusions, (6) The waysofthe windinto cyclone and a non-tangential direction into the annular internal dust collector, were dust collector with turbulent eddies of internal rotation mainly toproduce the highest position.It was that the outlet had the greatest amount of dust and dust had the best performance.
