Operation Essentials of Cyclone Dust Collector


The cyclone dust collector completes the dust removal process by rotating the dust-containing air in the cylinder body, so its operation and maintenance management are much more important than other mechanical dust collectors. The operation of cyclone dust collector includes starting, running and stopping, and the maintenance work is mainly the analysis, prevention and elimination of common faults.

1. Check before starting

1.1 Check whether each individual cyclone has been installed and is ready for starting. Start only when there is no problem.

1.2 Check the air tightness of the joint of each cyclone installation: check the air tightness of the joint of the dust collector (group) and the flue, the joint of the dust collector and the ash hopper, the ash hopper and the ash discharging device and the ash conveying device. To ensure that there is no enough to affect the performance of the cyclone dust leakage, gas leakage phenomenon.

1.3 After the check is completed, close the baffle valve to avoid overloading of the fan. Start the fan, no abnormal phenomenon, and gradually open the baffle to make the dust collector (group) pass the specified amount of dust containing gas.

2. Operation precautions

2.1 Pay attention to the change of wear parts. The most easily worn part of the cyclone dust collector is the inner wall of the outer cylinder that collides with the high-speed dusty gas.

2.2 Pay attention to check the change of gas humidity, when the gas humidity is reduced (caused by system operation or furnace shutdown), it is easy to cause dust adhesion, blockage and corrosion.

2.3 Pay attention to the change of pressure difference and smoke emission. Due to wear and corrosion, the cyclone dust collector perforates and causes dust emission, so the efficiency decreases, the smoke color deteriorates, and the pressure difference changes.

2.4 Pay attention to check the air tightness of each connecting part of the cyclone, and check the change of the gas flow rate and dust collection concentration of each unit cyclone.

3. Parking

In order to prevent the adhesion or corrosion of dust, after the system stops running, the cyclone dust collector should continue to run for a period of time until the air is replaced in the device before the operation of the dust collector can be stopped. In order to ensure the normal operation and technical performance of the cyclone, the following checks must be carried out when the cyclone is shut down:

3.1 Eliminate the dust attached to the inner cylinder, outer cylinder and blade, and remove the dust in the ash bucket;

3.2 Repair the perforation caused by wear and corrosion, and smooth the repair;

3.3 Check the air tightness of the combined parts and replace the seals if necessary.
