Top forms and is higher by open compartment 10-350 millimeters, covers entire opened type compartment（1）Top air water is atomized density wave, the density
Wave divergence principal direction is in train opened type compartment（1）Top is run to lower part, and air water atomization density wave, which both enclosed, coalings
Coal dust is from train opened type compartment in the process（1）The path of open topped diffusion And Movement, but have accumulated new dedusting energy along
The density wave divergence principal direction constantly dedusting repeatedly.
