| titleOfInvention | A kind of fly ash classification and heavy metal scale distribution analysis method and device |
| abstract | The invention belongs to the field of combustion pollutant detection, and specifically discloses a fly ash classification and heavy metal scale distribution analysis method and device. The method includes: performing preliminary screening on fly ash to obtain fly ash with a particle size of less than 100 μm; adding Fe-based dispersant to the screened fly ash, and uniformly mixing it with heated carrier gas to obtain mixed particles; The mixed particles are separated, and the mixed particles with a particle size greater than 10 μm are separated; the mixed particles with a particle size of less than 10 μm are classified to obtain the size distribution characteristics of the fly ash, and then the heavy metal content of the fly ash at all levels is analyzed to obtain the heavy metals. Scale distribution properties. The present invention utilizes Fe-based dispersant to reduce the electrostatic effect between fly ash particles, and at the same time reduces the adhesion and cohesion between particles, thereby promoting fly ash dispersion; in addition, the heated carrier gas is used to weaken the force between particles, thereby effectively improving the fly ash. Accuracy of ash classification and heavy metal scale distribution analysis. |
