In addition to the filter bag of the dust collector which is an important part of the bag filter, its filtrate is also one of the key filter components. In the process of using the bag filter, if you find that the filtrate is turbid, please don't hesitate, it must be a problem. So what happens to the filter bag that will cause the filtrate to become turbid?

1. The filter bag is retracted between the filter plates

In order for the filter bag to work normally during use, the two sides of the filter bag need to be relatively independent space, which requires the vigorous cooperation of the filter plate, and the edge of the filter bag is pressed against the edge of the filter plate. The filter bag is often larger than the For the filter plate, because the bag filter expands the filter chamber, the filter bag retracts into the filter chamber, so the filter bag will not play an important role, and the natural filtering effect will not be very good.

2. The rupture of the filter bag

Filter bags are woven from fibers, just like cloth, so filter bags have high flexibility and ductility. It is precisely because of this that filter bags are easily caused during the use of bag filters. Damage, especially when hard objects appear on the filtered material. When the filter bag is punctured, it will pass through the filter bag during operation, so that the filter will not have a great effect.

3. The mesh number of the filter bag is too small

The mesh number is an important parameter of the filter bag, and the size of the parameter indicates the number of filter holes in the filter bag. The smaller the mesh number, the larger the filter holes of the bag filter, on the contrary, the smaller the filter holes of the filter bag. Therefore, in the process of filtering the material, the filter bag with a small mesh will allow a lot of solids to pass through the filter bag in a normal way, which ultimately results in the liquid after the filtration is not clear.

There are more factors that the filter bags will affect filtrate like the air permeability, breaking strength, thickness etc, so it's very important to choose a good filter bag manufacturer!
