Description

Technical Field

[0002] The bag filter is a dry dust filter. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag filter, the large particles and heavy dust settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified.

[0003] However, current bag dust collectors are usually equipped with an observation window for easy observation of the internal conditions. Since the dust in the bag dust collector is high, the floating dust will adhere to the inner wall of the observation window, affecting the staff's line of sight.
