SHANDONG gas flow grinding briefly reasons why the bag dust collector dust removal is low.
Shandong airflow mill Briefly, the reason why the bag dust collector dust removal is low
The bag dust collector is a more mature product in the market, and the manufacturer skill of the production bag dust collector is uneven, some manufacturers have produced because of the immature skills. Many manufacturers have produced The dust collector dust removal power does not achieve any satisfaction. Regarding the dust removal system, a good product will also be disturbed by certain elements under certain elements. According to our multi-year dust collector production, the dust collector is summarized in the dust collector plan.
The primary impact elements are:
First, dust properties. The dust removal power of the bag dust collector is directly related to the heavy, severe, shape, electrostatic effects, and dust concentration of dust particles. According to Dongguan environmental experts, there is a high dust removal power with a large weight, large weight, irregular shape and electrostatic effect.
Second, dust bag performance. Filter cloth performance has a large impact on dust removal power and resistance. The filter cloth data should have the following conditions:
1, can obstruct the fiber dust passage, the hole in the fabric latitude is small, while the latitude and latitude line itself is fine to add the useful area of the sieve filter;
2, the fluffy hair of the fabric It is necessary to have a long and elastic, which make it masks the hole and has a certain intensity;
3. In order to facilitate the use of reverse airflow finishing, the fluffy fluffs of the fabric are connected to the air touch.
Third, the lower the filtering speed, the less the filter speed is, the more the particles are small and the porosity is large and the porosity is large, the more the dust granules are captured, and the filter is too high, and the dust granules are added. The penetration of the filtration is lowered by the filtering power. Of course, the penetration phenomenon can also be defeated by a suitable filter material. In addition, some filter materials, the filter speed changes in the scale, and the dust removal power is almost unaffected.
Fourth, the filter material is affected by the dust filter in the bag type dust collector, there is no dust layer on the new filter material. At this time, the capture dust can be low. As the filter powder process is carried out, the dust layer is gradually composed. The dust removal power is improved. When the dust layer is completely composed, the filtration power can reach 99%, regarding less than 1 μm dust grain, there is a good capture action.
Fifth, leakage and resistance: Theoretically calculates the dust removal power of 99%, but the measurement is not met, the primary is the influence of leakage and resistance, the lower the drainage, the better the dust; Resistance is a must to affect dust removal electrostatic precipitator, often emptying the filter bag, cutting resistance, and progressive dust removal. The dust mask should be as close as possible to the head, so that the dust is simpler into the cover, add dust, and cuts no discharge pollution.
