Daily use and maintenance of filter cartridge dust collector

Daily use and maintenance of filter cartridge dust collector

A filter cartridge dust collector is composed of a filter cartridge as the filtering element or a dust collector using pulse blowing. If there are frequent problems during use, it is somewhat related to our daily maintenance work. Next, the editor will introduce the daily use and maintenance of the filter cartridge dust collector.

1. Inspection of electrical control components

Electronic control components: significantly different from other parts of the filter cartridge dust collector. The electronic control components do not need to work regularly, but we recommend using the interval time of the dust collector for inspection and maintenance to confirm their good performance. The inspection of overall components such as solenoid valves can be carried out by replacement.

2. Tightness inspection of filter cartridge dust collector

When there is water vapor such as small puddles or rust spots inside the filter box, it is caused by water vapor or leakage from the outside.

The problem with water vapor is caused by the condensation of hot flue gas due to low operating temperatures. If water vapor is caused by leakage, the box of the filter cartridge dust collector should be cleaned first, and then the leakage should be blocked. Sealed welding can be used. However, before welding, the filter element must be removed or covered to prevent fatal damage to the filter element caused by welding sparks.

3. Pneumatic valve inspection

Pneumatic valve inspection: can be determined based on its daily operating status. If the pneumatic valve does not work, check whether the pneumatic and electrical connections are normal. If the connection is correct, check if the solenoid valve is damaged. If damaged, replace the solenoid valve immediately. If the action is incorrect, first check if the intake and exhaust pipes are connected in reverse. If the connections are reversed, please replace them. If the solenoid valve operates abnormally after replacement, check whether the solenoid valve is damaged.

4. Filter chamber and filter cartridge

Regularly inspect the filter chamber and filter cartridge for dust, water vapor, or rust spots. When these problems occur, it means that the filter element is damaged or the operation process is incorrect. During use, the emission concentration at the exhaust port should be observed in a timely manner. If there is fly ash emission, the damage of the dust removal filter element and the sealing of the filter chamber should be checked in a timely manner, and the air leakage holes should be blocked. If any of the above situations occur, the dust filter element should be replaced immediately.

5. Inspection of maintenance doors

The leakage of maintenance doors is usually caused by incorrect fastening or gasket problems. Correctly fasten the maintenance door, replace the aging and deformed gasket, and solve the leakage problem of the maintenance door.

6. Diaphragm valve inspection

The faults of diaphragm valves are generally divided into opening and closing faults. Among them, the opening fault may be due to the continuous operation of the diaphragm valve, excessive accumulation of internal impurities, and severe wear of the diaphragm. The continuous leakage sound of the diaphragm valve can detect the cause of the malfunction.

After identifying the cause of the malfunction, first turn off the pressure system device, then remove the diaphragm valve cover, check for debris at the diaphragm seal, whether the diaphragm is damaged, and whether the spring is intact. The closing fault of the diaphragm valve can be determined by the sound of the valve. When the valve does not operate or the solenoid valve partially operates but the valve does not operate, it indicates that there is a problem with the solenoid valve or controller and it needs to be replaced.
