1. What is the filter wind speed? The filter wind speed is an important technical and economic index that reflects the ability of the bag filter to handle gas. It has a great influence on the work and performance of the bag filter.
2. Influence of wind speed on the equipment: When the filtration speed is high, the filtration area and volume can be reduced, the floor area can be reduced, and the investment can be reduced. However, the high selection of filtration wind speed will affect the dust removal efficiency, increase the difficulty of cleaning, and filter resistance. Increase, reduce the life of dust filter bag, bring the problem of increase in operation and maintenance costs. In fact, the choice of wind speed is a more complex task. It is not enough to treat the above advantages and disadvantages in isolation. Solving this problem is the most important. Important. Difficulties of wind speed to dust removal accessories: In recent years, under the increasingly stringent environmental protection requirements, it is very important to properly select the filter wind speed of the dust collector in the work of designing bag dust removal equipment.
3. Improve the impact of wind speed: Under the premise of constant air volume, increasing the filtration rate can save the filter material and improve the processing capacity of the filter material. However, after the filtration rate is increased, the resistance of the equipment increases, the energy consumption increases, and the operating cost increases. At present, if the filtration rate is too high, the dust layer accumulating 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, micro-dust will penetrate into the filter media, even through the filter, so that the outlet dust concentration increases. High filtration speeds can also result in the rapid formation of dust layers on the filter media, causing frequent cleaning, increasing the energy consumption of cleaning, and shortening the service life of filter bags.
4. What are the aspects of low wind speed?
At low filtration speeds, the pressure loss is low and the efficiency is high, but the area of the filter bag required also increases, and the volume, floor space, and investment costs of the dust collector also increase. In general, the treatment of fine or difficult to collect dust, dust gas temperature is high, the dust concentration is high and the moisture content of the flue gas is large, a lower filtration rate should be taken.
