1, what is the filter wind speed: The filter wind speed is an important technical and economic indicator that reflects the gas processing capacity of the bag dust collector, which has a great impact on the work and performance of the bag dust collector.
2, the impact of wind speed on the equipment: when the filter wind speed is high, the filter area and volume can be reduced, the footprint can be reduced, and the investment can be reduced. However, the selection of filter wind speed is high, which will affect the dust removal efficiency, increase the difficulty of cleaning, increase the filtration resistance, reduce the service life of the dust filter bag, and bring about the problem of increased operation and maintenance costs. In fact, the selection of wind speed is a more complex work, looking at the advantages and disadvantages of the operation in isolation is not enough, to solve this problem is the most important. The problem of wind speed on dust removal accessories: In recent years, in the case of more and more stringent environmental protection requirements, in the design of bag dust removal equipment, the filter wind speed of the filter filter reasonably selected has become very heavy.
3, improve the impact of wind speed: under the premise of the same air volume, improve the filtration speed can save filter material, improve the processing capacity of filter material. However, after the filtration speed increases, the equipment resistance increases, the energy consumption increases, and the operating cost increases. At present, the filtration speed is too high, the dust layer accumulated on the filter bag will be compacted, and the filtration resistance will increase. Due to the large pressure difference between the two sides of the filter bag, fine dust will penetrate into the filter material, and even through the filter material, so that the dust concentration at the outlet will increase. High filtration wind speed will also lead to the rapid formation of a dust layer on the filter material, causing too frequent cleaning, increasing the cleaning energy consumption, and shortening the service life of the filter bag.
4, the impact of low wind speed: at low filtration speed, less pressure loss, high efficiency, but the required filter bag area is also increased, the volume of the dust collector, land area, investment costs should also increase. Generally speaking, when dealing with fine or difficult to capture dust, high dust gas temperature, large dust concentration and large humidity content of flue gas, a lower filtration rate is appropriate.1, what is the filter wind speed: The filter wind speed is an important technical and economic indicator that reflects the gas processing capacity of the bag dust collector, which has a great impact on the work and performance of the bag dust collector.
