Gravity precipitator is a commonly used gravity precipitator with the same airflow direction as the dust settling direction. The difference between this gravity precipitator and inertial precipitator is that the former does not have airflow blades, and the dust removal force is mainly gravity.
Vertical airflow gravity precipitator has two structural forms. One is that the direction of the dust-laden airflow at the inlet is opposite to the direction of gravity sedimentation of the dust particles, and the other is that the direction of the dust-laden airflow at the inlet is the same as the direction of gravity sedimentation of the dust particles. Since the particle sedimentation is in the same direction as the airflow, the gravity dust collector has a fast sedimentation process and easy separation.
The vertical airflow precipitator is essentially a wind sorter, which can remove particles whose sedimentation speed is greater than the airflow rise speed. After the airflow enters the dust collector, due to the change of direction of the airflow, large particles settle around the inclined bottom and fall down the top pipe.
In general, when the velocity of this type of dust collector is 1.5 ~ 2m / s, it can remove 200 ~ 400µm dust particles.
