The eight common faults of pulse bag dust collectors and their handling methods:
Bag damage: Bag damage is one of the common faults of the pulse bag dust collector. It is mainly caused by wear, corrosion, high-temperature damage or improper dust removal. The solution is to regularly check the condition of the bags and replace the damaged ones in time. Optimize the dust removal parameters to avoid excessive dust removal that may cause bag damage. Select high-quality, wear-resistant (based on actual reports) (based on actual reports), and corrosion-resistant (based on actual reports) (based on actual reports) bag materials to extend the service life of the bags.
2. Pulse valve failure: The pulse valve fails to function properly or operates abnormally, resulting in poor dust removal effect and affecting the dust removal efficiency. Check whether the power supply, air source and solenoid valve of the pulse valve are operating normally. Remove impurities and moisture from the air path. Replace the damaged diaphragm or solenoid valve. Regularly inspect the working condition of the pulse valve to ensure its smooth operation and good performance.
3. Airway blockage: Airway blockage hinders the smooth flow of the dust removal air, thereby affecting the dust removal efficiency. Check if there are any foreign objects or accumulated dust in the airway pipes and clean them up. For the easily blocked areas, set up inspection ports and conduct regular maintenance.
4. Abnormal increase in pressure difference: The pressure difference between the inlet and outlet of the dust collector has increased abnormally. This may be caused by clogged filter bags, insufficient air volume, or system leakage. Strengthen the management of the bag dust removal system to prevent filter bag blockage. Check and adjust the air volume of the fan to ensure it meets the dust removal requirements. Check the sealing performance of the system and promptly address any leakage points.
5. Fan malfunction: If the fan vibrates, makes loud noises or has insufficient airflow, it will affect the dust removal efficiency. Check whether the bearings and the motor are damaged and replace them in time. Clean the inlet and outlet of the fan to ensure smooth airflow.
6. Excessive ash accumulation in the ash hopper: Excessive ash accumulation in the ash hopper hinders the ash discharge process and may even cause equipment blockage. Optimize the ash discharge plan, ensure timely handling of the accumulated ash in the ash hopper. Check whether the ash discharge device is operating normally and promptly clean or replace faulty components.
Control system failure: The control system is abnormal or unable to control the equipment, which affects the normal operation of the dust collector. Check if the sensors and line connections are normal, and eliminate hardware faults. Check if the control program is incorrect or needs to be updated, and debug or upgrade the software.
8. Condensation on filter bags: Condensation forms on the surface of the filter bags, resulting in reduced dust removal efficiency and damage to the bags. Analyze the causes of condensation, such as low flue gas temperature, high humidity, or insufficient insulation of the dust collector.
