Dust filter selection factors to be considered one, air volume (Q) is the air volume per unit time in dust removal equipment can purify the volume of gas volume. Units of cubic meters per hour (m3 / h) or standard cubic meters per hour (Nm3 / h). A bag filter design is the most important factor. According wind baghouse design or selection, generally can not make dust exceeds the amount of wind in the case of running, otherwise, the bag is easy to plug, shortened life expectancy, the pressure loss increased significantly, but also reduces the collection efficiency; but not The selected air volume is too large, otherwise the increase in equipment investment and floor space. Reasonable choice air volume is often the case according to the process and experience to decide. 2, the use of temperature for the baghouse, the use of temperature depends on two factors, the first is the maximum temperature of the filter, and the second is the gas temperature must be above the dew point. Currently, as a large selection of glass fiber filter media, the maximum temperature up to 280 ℃, right above this temperature gas cooling measures must be taken, right below the dew point temperature of the gas tiouine measures must be taken. On the baghouse, the use of temperature and dust removal efficiency relationship is not obvious, which is different from the electrostatic precipitator of ESP, the temperature change will affect the specific resistance and other effects of dust collection efficiency. 3, the inlet dust concentration that is the entrance of dust concentration, which is the point from the dust of the decision process, in the design or selection baghouse, it is second only to deal with air flow is another important factor. Expressed in g/m3 or g/Nm3. For the baghouse, the inlet dust concentration will directly affect the following factors: ⑴ pressure loss and the cleaning cycle. Inlet concentration, fouling the same speed on the filtering area, the pressure loss increases, the result is forced to increase the cleaning frequency. ⑵ bag and box wear. In strong abrasive dust case, the wear amount can be considered proportional to the concentration of dust. ⑶ advance whether the necessary dust. Advances in the precipitator dust is increased again before the entrance to a dust removal equipment, also known as pre-dedusting. ⑷ ash ash discharge device capabilities. Ash ash discharge capacity of the device should be able to accept all the dust discharge prevail, equal to the amount of dust inlet dust concentration multiplied by the air volume. ⑸ operation. Baghouse is divided into positive and negative two modes of operation, in order to reduce the fan wear, inlet concentration should not be a big positive pressure mode of operation. 4, the outlet dust concentration outlet dust concentration refers to the concentration of dust emissions, which means that the same way inlet dust concentration, outlet dust concentration should be sized to local environmental requirements or the user's requirements prevail, baghouse emission concentration general can reach 50 g/Nm3 less.
