large boiler dust collector

A large boiler dust collector is used to introduce dusty gas from the guide pipe into the ash hopper of each unit. Under the guidance of the ash hopper guide system, large particles of dust are separated and directly fall into the ash hopper, while the remaining dust enters the middle box filtration area with the airflow. The filtered clean gas is discharged through the filter bag, the box, the lift valve, and the exhaust pipe. As the filtration progresses, when the dust accumulation on the surface of the filter bag reaches a certain amount, the dust cleaning control device closes the lift valve and opens the electromagnetic pulse valve according to the set program.

A large boiler dust collector is a unit combination dust removal equipment with high air volume, good ash removal effect, and good operation.

Key points for installing large boiler dust collectors

⑴ Gravity settling - When the dusty gas enters the bag filter, the large and heavy dust particles settle under the action of gravity, similar to the settling chamber.

⑵ Filtering function - When the particle diameter of the dust is larger than the gap between the fibers of the filtering material or the gap between the dust on the filtering material, the dust is called the filtering effect when the airflow passes through. When the accumulation of dust on the filter material increases, this effect becomes more pronounced.

⑶ Inertial force - When the airflow passes through the filter material, it can bypass the fibers, while larger dust particles still move in the original direction under the action of inertia force, and then collide with the filter material and are captured.

⑷ Thermal motion effect - Light bodied small dust (less than 1 micron) moves with the airflow, very close to the airflow line, and can bypass fibers. However, upon collision with gas molecules undergoing thermal motion (i.e. Brownian motion), they change their original direction of motion, increasing the chances of dust coming into contact with fibers and capturing the dust. The finer the diameter of the filter fiber, the smaller the gap ratio, and the higher the capture rate, which is more conducive to dust removal.
