Dust filter bag is a kind of efficient dust filter material, generally take polyester short fiber or long fiber as raw material, the service life is generally 4-6 times that of glass fiber fabric, with good ventilation performance, high dust removal efficiency, and a certain acid, alkali and heat resistance, the weaving process uses multilateral flapping, improve the thickness of the fabric, elastic, dust removal effect is very good, The dust removal rate is 99.999%.
1. Use temperature
The correct selection of dust bag suitable for the corresponding dust temperature is the key to the filter bag. If the temperature is too high, the selected dust filter bag to exceed the normal use temperature, dust filter bag manufacturer filter bag light will shorten the service life, serious will burn in a short time. Therefore, when selecting the filter bag, it is necessary to determine and calculate the inlet temperature of the dust collector, and select the corresponding dust bag.
2, filter wind speed
The filter speed of the bag dust collector is too high, which is the main reason for the damage of the dust bag. In recent years, some units blindly reduce the cost of equipment, increase profits, in the design of bag dust collector, the filter wind speed is increased, the user has no obvious reaction in a short time, but greatly shorten the service life of the filter bag.
3. Product quality
In recent years, some small manufacturers use small sewing machines as processing equipment, and the processing of inferior thread as raw materials, false and true, the processing level is far behind. So that the dust bag in the use of time is not long, the phenomenon of opening, cracking, falling off the bottom. Although the bag size is slightly smaller, it can also be used, but after adsorbing the dust with a larger proportion, the bag phenomenon will appear after a period of use.
The filter bag is the heart of the bag dust collector in the process of operation. Usually, the cylindrical pulse filter bag is vertically suspended in the dust collector. The dust containing gas enters the dust collector by the air inlet and passes through the guide plate of the dust hopper, so that some large particles in the gas are separated by the action of inertia force and fall directly into the dust hopper. The dust containing gas enters the filter bag filter area of the box, most of the dust is captured on the outer surface of the filter bag, and the clean gas enters the filter bag through the filter material, and the purified gas enters the upper box through the filter bag mouth, and then is discharged by the outlet. The cage inside the filter bag is used to support the filter bag, prevent the filter bag from collapsing, and it helps to remove and redistribute the dust cake.
