Comparison of high temperature and mechanical damage for filter bags

Comparison of causes of high temperature damage and mechanical damage of dust filter bags

1. Causes and phenomena of high temperature damage to the dust filter bag. 

Open flame sparks. Reason: There is sparks in the smoke, causing small holes to burn. Phenomenon: There are small holes on the dust bag. High temperature flue gas. Reason: The temperature of the working condition of the cloth bag exceeds the tolerance range of the cloth bag, and the heat shrinkage of the cloth bag is too large and the cloth bag is damaged. Phenomenon: Severe shrinkage or severe hardening, twist the rotten part of the cloth bag with your hands, if it breaks into powder 

2. Reasons and phenomena of mechanical damage to the dust filter bag. 

The bag mouth is damaged. Reasons: the compressed air is too high; the blowing pipe is skewed; the flower plate is deformed, etc. It is an installation quality problem. Phenomenon: The mouth is blown within 30-40 cm (from the bottom to the outside). The bag body is damaged. Reason: The size of the cloth bag and the frame do not match, and the surface finish of the dust removal frame. Phenomenon: The contact part of the bag body and the frame is damaged. The bottom of the bag is damaged. Reason: The bottom of the frame is too small or the bag is too long, and the dust removal operation is too large, causing the inside of the bag to grind; or the dust accumulation is too high to form a vortex wear bag. Phenomenon: The bottom of the bag is worn.
