Abstract EN
The grading separation of coal ash can not only increase its economic value but also decrease its pollution to environment.
Based on the jet-attracting flow technology and the gas-solid two-phase flow theory, the force and motion of coal ash particles in airflow were studied firstly.
Focused on single coal ash particle, Matlab software was used to simulate the force conditions and separation parameters of various diameter coal ash particles in airflow.
Fluent software was used to simulate the nozzle fluidization domain shape and to determine optimal jet flux.
According to the theoretical results, a coal ash collecting and grading system was developed.
Using the separation efficiency as the evaluation index, the optimal experiment parameters of jet flux, attracting flux, and separation time were obtained.
At last, the calculated results and experimental results of coal ash particles median diameter from the first grading separation exit under various attracting fluxes were compared.
The reasons that could cause the errors were discussed.
This study has significant practical meaning and application value on coal ash collecting and grading separation.
