How to design the air volume of the boiler dust collector Whether the treatment air volume of the boiler dust collector can achieve the ideal dust removal effect, so it needs to be considered in many aspects in design, and must be correctly selected to achieve effective operation. 1. When determining the air volume of the boiler dust collector, it is generally impossible to operate the boiler dust collector in excess of the specified air volume. Otherwise, the filter bag is easily blocked, the service life is shortened, the pressure loss is greatly increased, and the dust removal efficiency is also reduced; It is also impossible to select the air volume too large, otherwise it will increase equipment investment and floor space. 2. The air volume unit is expressed by m3/min and m3/h, but it must pay attention to the location of the dust collector and the temperature of the flue gas. High-temperature gas contains a lot of water, so the air volume is not expressed by dry air but by humidity gas volume, and moisture is expressed by volume fraction. 3. Because the performance of the bag filter depends on the actual filtered wind speed of the humid air, if the treatment temperature of the boiler precipitator has been determined and the cooling of the gas is followed by the dilution method, then the treatment of the boiler precipitator at this temperature The amount of air, as well as the amount of diluted air. When calculating the required filtration area, the filtration rate is the actual filtration speed. 4. In order to adapt to the change of dust source, in the design of boiler dust collector, it is necessary to add some reserve air volume above the normal air volume, so that the bag type dust collector is designed according to the air volume. If the boiler dust collector is operated under the conditions of the specified treatment air volume and filtration speed, the pressure loss will increase greatly, the filter cloth may be clogged, the dust removal efficiency will also be reduced, and even the cause of other fault frequency rises sharply. However, if the reserve air volume is too large, the investment cost and operating cost of the boiler dust collector will increase. 5. As the temperature of the dust source changes, the air volume of the pulse dust collector also changes. However, the large amount of wind should not be estimated by the misuse of dust sources and occasional faults. 6. Once the treatment air volume is determined, the required filtration area can be determined according to the determined filtration speed. The filter speed varies greatly depending on the form of the bag filter, the type of filter cloth, and the manufacturing process. The size of the filtration rate can be consulted based on relevant data or similar production processes and is estimated based on experience.
