How to avoid air dust filter bag damage

A. The number of vertical ribs of the filter bag cage should be reasonably matched according to the raw materials of the filter material, and the lubrication should be flat without blemishes, with sufficient strength, straightness up to the industry standard, and good coordination with the filter bag.

B. The flower plate is flat, the inner surface of the tube sheet hole is lubricated, and the tube sheet hole is separated from the box wall and the tube sheet hole with a large interval to avoid the error of the tube sheet and the skew of the bag cage, which will lead to the collision between the filter bags and the filter bag. Bags are worn.

C. The pulse nozzle should be straight and should be concentric with the diamater of the tube sheet, and the error should be less than 2mm.

D. The arrangement of the pulse nozzle has an important influence on the pulse cleaning of the bag filter. The pulse nozzle is separated from the mouth of the filter bag. If it is too small, the induced air flow will be insufficient, and the upper bag mouth of the filter bag will be easily damaged; if it is too large, the pulse The pressure attenuation of the airflow is too large, which is not conducive to the movement of the airflow into the bag. The detailed pulse interval is related to the diameter of the pulse nozzle, the parameters of the pulse air flow, and the diameter of the bag. It is necessary to ensure that the pulse air flow and the induced air volume are greater than the volume of the filter bag.

E. The air distribution board should be set for the air intake smoker of the dust collector, so that the air distribution of each box is relatively uniform. The position and number of the air distribution board have a great influence on the air distribution.

F. There should be a certain interval between the bottom of the 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 unloaded in time.

Dust Filter Bags are widely used in steel, cement, chemical industry, power plants, road construction, metallurgy, food processing, etc.
