How does the filter bag affect filtration?
The dust collector bag is an essential component of the bag filter, and the filtrate is a key filter component. If the filtrate becomes turbid during use, it can indicate a problem with the filter bag. Let's explore some common reasons why the filter bag may cause turbid filtrate.
Filter Bag Retraction Between Filter Plates
For the filter bag to function correctly, the two sides of the dust filter bag need to be separated by the filter plate. The edge of the filter bag should be pressed against the edge of the filter plate. However, the filter bag may retract into the filter chamber due to the filter chamber expansion caused by the bag filter. As a result, the filter bag will not be effective, and the natural filtering effect will be compromised.
Filter Bag Rupture
Filter bags are woven from fibers, making them flexible and ductile. However, this also makes them susceptible to damage during the use of bag filters, especially when filtering materials with hard objects. When the filter bag is punctured, the filtrate may not be adequately filtered, leading to turbidity.
Filter Bag Mesh Number Too Small
The mesh number of the dust collector filter bag is a critical parameter. It indicates the number of filter holes in the bag filter, with smaller mesh numbers meaning larger filter holes and vice versa. During material filtration, a filter bag with a small mesh number may allow a significant amount of solids to pass through in a normal way, resulting in unclear filtrate.
Other factors such as air permeability, breaking strength, and thickness can also affect the filtration effectiveness of the filter bag. Therefore, it's crucial to choose a reliable and trustworthy filter bag manufacturer.
In conclusion, understanding the common reasons why the dust filter bag causes turbid filtrate can help in identifying and resolving problems quickly. By ensuring proper use and maintenance of the filter bag, you can prolong the life of your bag filter and maintain high-quality filtrate.
