The filter bag is the key element that determines the dust removal efficiency and working temperature of the bag filter. The cost of replacing the filter bag is also the main maintenance cost of the bag filter. Therefore, the working life of the filter bag is related to the operating condition and cost of the dust collector. Therefore, the daily maintenance and maintenance of the dust collector skeleton is very important. So how can the life of the dust removal skeleton be extended?
- The correct method of use: ensure that the filter bag of the dust collector is operating under the working conditions it adapts to. If the working conditions change, it should be immediately switched to bypass or empty to prevent adverse effects on the life of the filter bag.
- Correct dust cleaning method: During the use of the filter bag, the dust area gradually increases and the pressure difference rises. The dust should be effectively separated to keep the pressure difference between the inside and outside of the filter bag within the set range.
- Select the appropriate filter material: the filter material should be selected according to the humidity, temperature and chemical characteristics of the gas, the size, weight, shape of the particulate matter, whether it is pecked, and the dust concentration, filtration speed, cleaning method, emission concentration and bag Factors such as the working system of the dust collector are comprehensively considered. Generally, the needle jet felt is used for the pulse jet bag filter, and the woven cloth is used for the sub-chamber reverse blow bag filter or the mechanical vibration bag filter.
- Reasonable structure: It should meet the requirements of the filter and dust removal of the bag filter, and it is easy to install and reliable in sealing. Pursuing the corresponding filtration area and good filtration state, it is easy to remove dust and try to avoid wear. Reasonable coordination with related parts. If the outer filter type synthetic fiber filter bag and the frame should be loosely matched, the outer filter type glass fiber filter bag should be tightly combined with the small spacing vertical bar frame; the inner filter type filter bag should consider and set the filter bag tension.
- Superb sewing technology: the sewing size meets the design requirements, and the heat-shrinkable size is reserved according to the type of filter material and the use temperature. The stitch pitch is reasonable, without stitch skipping or thread breakage, and the stitching meets the requirements. Reasonable fit, no burr or breakage to damage the filter bag. The entire filter bag is free of defects such as small holes, yarn skipping, and fouling, and has proper packaging. It will not be damaged or damp during storage and transportation. The glass fiber filter bag should not be pressed and stored for too long, otherwise it will affect the service life.
