Wear of dust filter bag is the main type of reverse failure of bag filter. After the hole is broken due to the back damage of other bag filters, the airflow erosion caused by dust will lead to additional wear. Wear is closely related to structural design, air distribution and back soot blowing of bag filter. Today, the filter bag manufacturer will explain to you where PPS filter bags are usually damaged.

Which part of PPS filter bag is easy to break?

There are five reasons for wear of PPS filter bag, including dust removal at bag mouth, bag body, bag lower part, bag bottom and bag inside, wear of components and its influencing factors. When the damage flows out from the inside, the vertical tendons of the frame (also called dust removal bones) come into contact, and the desoldering or corrosion of the vertical tendons of the frame may prevent the filter bag and PPS filter bag from exerting pressure or blowing excessively, or blowing frequently, and folding and breaking at the contact position between the filter and the frame.

These wear problems can be solved by replacing the fixed frame or adjusting the injection device. The wear on the outer side of the lower part of the PPS filter bag moves upwards by about 30 cm from the bottom of the PPS filter bag, with one side worn and the lower part seriously worn, which gradually decreases. Local sewing thread has no worn position, and the strength of sewing thread is better. This kind of wear is caused by deformation of fire plate, small hole distance, cage deformation and too long PPS filter bag.
