CEMENT DUST TREATMENT SYSTEM
* Treatment procedure:
- Dust generated during the production process is collected into the suction cup placed on top of the equipment. Exhaust fans on the pipe will draw and guide dust into the cyclon to separate dust from the air. Air mixed with dust enters the device by the method of tangent to the cylinder and the circular rotation moves downwards, when encountered the airflow is pushed back up to the vortex movement in the inner cylinder and continues to switch to the device. filter cloth bag.
- The movement of the air stream in the cyclon of dust particles under centrifugal force hits the wall of the tank, loses its inertia and falls.
- In the filter bag, the remaining air and dust cloth will go through the filter cloth, dust particles larger than the gaps between the fabric fibers will be retained on the surface, the smaller particles will stick on The fiber surface of the filter material is subject to collision, gravitation and electrostatic attraction, and the resulting dust layer gradually thickens to form an inert filter film that can hold most of the fine particles.
- After a while, the dust layer will be very thick, causing the resistance of the film to be too large, we have to stop and proceed to remove the dust on the fabric surface. The gas after being filtered through cloth bag filters is drawn through the chimney and discharged into the environment according to QCVN 19: 2009 / BTNMT..
