Flumes dust bag is added with P84 fiber on the basis of glass fiber needled felt to make the felt layer more compact, and the entanglement between the fibers is strengthened, which can cope with higher filtering wind speed.

The P84 fiber has a trilobal cross section, which increases the chance of dust catching. Moreover, the special cross-sectional shape of the fiber makes most of the dust concentrated on the surface of the filter material, which is more difficult to penetrate into the filter material and block the gaps, reducing the running resistance and thus improving Filter wind speed.

The mouth of the flumesi dust removal cloth bag and the bag body are connected with a single single needle thread and two double needle threads; the bag body is sewn by a filter material crimping device with three needles and six threads, the needle pitch is 28-35 needles/10cm, and its width It is 6-9mm; the bottom material of the bag body should be turned outwards and upwards with a reinforcement layer of 100mm bottom; the side material of the reinforcement layer should be turned inward and sewn with double needles, and the three-needle stitching on the seam surface of the bag body should be vertical to the bag Mouth, without bending.

The body and bottom of the flumesi dust bag are sewn with double or three needle stitches; the bottom of the bag body and the bottom of the bag have a distance of 10-12mm; the bottom of the bag body can be upright, and the bottom of the bag has a reinforcing layer and a double bottom.

1. The pore size of the bag membrane of the film-coated Fluormes needle-punched felt dust collector is between 0.23um, and the filtration efficiency can reach more than 99.99%, and almost zero emission is achieved. After cleaning, the porosity is not changed, and the dust removal efficiency is always high.

2. When the coated dust bag is used, the pressure loss is higher than that of the ordinary dust bag, but after it is put into operation, the pressure loss changes little with the increase of the use time. The pressure loss of the ordinary dust bag will increase with the extension of the use time. getting bigger.

3. The dust can easily enter into the ordinary dust bag in use, and it accumulates more and more, until the pores are blocked, causing it to be unusable. With the use of PTFE coated dust bag, the filtered dust can be easily removed from the surface of the film, the cleaning effect is good, the cycle is long, and the cleaning pressure intensity in use is low, which improves the service life of the dust bag and can Significantly reduce the maintenance workload of the dust collector and reduce the operating cost of the product. It is laminated with woven dust bag and needle-punched filter felt to make PTFE coated dust bag, which is widely used in flue gas purification and dust removal. Governance and special recycling and other fields.

4. The coated dust bag also has good chemical stability, heat resistance and chemical corrosion resistance.
