Maintenance method of dust filter bag

1. There should be a certain distance between the bottom of the dust filter bag and the ash hopper. There should be a high and low level gauge in the ash hopper. When there is too much ash in the ash hopper, the ash should be discharged in time.

　　2. Before installing the dust filter bag, the site should be clean and tidy, the dust filter bag cage blowpipe and other facilities should be placed orderly, the impurities in the dust removal equipment should be cleaned up, the installation process should be in order, and there should be no cross operations that affect the filter installation.

　　3. In order to eliminate the sparks that may appear in the flue gas, an effective preventive measure is to install a spark catcher before the flue gas enters the dust collector to remove the sparks from the flue gas.

　　4. Affected by regional climate differences, the dust collector is required to have good airtightness and heat preservation of the cabinet to prevent local cooling and condensation of the dust removal equipment.

　　5. After the dust removal bag is installed, the dust removal filter bag should be pre-sprayed with lime powder and talcum powder before the dust removal equipment starts to operate. The effectiveness of the dust bag is not only related to the quality of the dust bag itself, but also to the reasonable design of the dust collector, as well as the installation, operation and maintenance of the dust bag.

　　6. The number of vertical ribs of the dust removal framework should be reasonably matched according to the material of the filter material, and it should be smooth and flat without blemishes, with sufficient strength, verticality up to industry standards, and a good fit with the dust removal cloth bag.

7. The flower plate is flat and the inner surface of the flower plate hole is smooth. There is a large distance between the flower plate hole and the box wall and the flower plate hole to prevent the error of the flower plate and the inclination of the skeleton, resulting in the collision between the dust cloth bags and the dust removal The cloth bag is worn out.

　　 8. The pulse nozzle should be vertical, and should be concentric with the pattern hole, the error is less than 2mm.

9. The arrangement of the pulse nozzle has an important effect on the pulse cleaning of the bag filter. The pulse nozzle is a distance away from the dust bag mouth. If it is too small, the induced air flow is insufficient, and the upper bag mouth of the dust bag is easy to be damaged; when it is too large, the pulse The pressure attenuation of the air flow is too large, which is not conducive to the air flow to the bag. The specific pulse distance is related to the pulse nozzle diameter, pulse air flow parameters, and bag diameter. It is necessary to ensure that the pulse air flow and induced air volume are greater than the volume of the dust collection bag.

　　10. Airflow distribution plates should be installed for the air intake smokers of the dust collector to make the air distribution of each box relatively uniform. The position and number of the air distribution plates have a great influence on the air distribution.
